Perinatal research and the Tooth Fairy
How much did you get per tooth from the Tooth Fairy? How much do your children or grandchildren receive each time they lose a baby tooth? In my family the Tooth Fairy seems to be more than keeping with inflation. Has she ever been caught in the act of swapping cash for enamel in your home? Has she every slipped up one night but managed to resurrect her credibility the following night by doubling the reward? And, by the way, what does the Tooth Fairy do with all those teeth, and who’s funding her nocturnal switcheroos?
A recent study from the Center for Genomic Medicine at the Massachusetts General Hospital in Boston may provide an answer to at least one of those questions. It turns out some researchers have been collecting baby teeth in hopes of assessing prenatal and perinatal stress in infants.
Not surprisingly, teeth are like trees, preserving a history of the environment in their growth rings. The Boston researchers hypothesized that the thickness of one particular growth line referred to as the neonatal line (NNL) might reflect prenatal and immediate postnatal environmental stress. Using data and naturally shed teeth collected in an English longitudinal study, the authors discovered that the teeth of children whose mothers had a long history of severe depression or other psychiatric problems and children of mothers who at 32 weeks’ gestation experienced anxiety and/or depression were more likely to have thicker NNLs. On the other hand, the teeth of children whose mothers had received “significant social support” in the immediate postnatal period exhibited thinner NNLs.
Based on anecdotal observations, I think most of us already suspected that the children whose mothers had significant psychiatric illness began life with a challenge, but it is nice to know that we may now have a tool to document one small bit of evidence of the structural damage that occurred during this period of stress. Of course, the prior owners of these baby teeth won’t benefit from the findings in this study; however, the evidence that social support during the critical perinatal period can ameliorate the damage might stimulate more robust prenatal programs for mother and infants at risk in the future.
It will be interesting to see if this investigative tool becomes more widely used to determine the degree to which a variety of potential perinatal stressors are manifesting themselves in structural change in newborns. For example, collecting baby teeth from neonatal ICU graduates may answer some questions about how certain environmental conditions such as sound, vibration, bright light, and temperature may result in long-term damage to the infants. Most of us suspect that skin-to-skin contact with mother and kangaroo care are beneficial. A study that includes a survey of NNLs might go a long way toward supporting our suspicions.
I can even imagine that a deep retrospective study of NNLs in baby teeth collected over the last 100 years might demonstrate the effect of phenomena such as wars, natural disasters, forced migration, and pandemics, to name a few.
It may be time to put out a nationwide call to all Tooth Fairies both active and retired to dig deep in their top bureau drawers. Those little bits of long-forgotten enamel may hold the answers to a plethora of unanswered questions about those critical months surrounding the birth of a child.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Enriched infant formula offers no academic benefit later: Study
Infants who are given nutrient- or supplement-enriched formula milk do not later have higher academic scores as adolescents than those fed with standard formula, a study published online in the BMJ suggests.
One goal of modifying infant formula has been to make long-term cognitive outcomes similar to those for breast-fed infants, the authors noted. Rates for breastfeeding beyond 6 weeks are low in many parts of the world and more than 60% of babies worldwide under the age of 6 months are given formula to replace or supplement breast milk, the paper states.
So far, research has been inconclusive on benefits, though enhancements continue to be added and claims have been made as to their benefits on cognition in advertising. Long-term trials are difficult as researchers move on and participants are lost to follow-up.
In a new study, however, researchers led by Maximiliane L. Verfürden, MsC, with the University College of London’s Great Ormond Street Institute of Child Health, linked data from seven dormant, randomized, controlled infant formula trials to participants’ performance later as adolescents in the United Kingdom on mandatory national school math and English exams at ages 11 and 16 and found no difference in scores.
They followed 1,763 adolescents who had been participants in the formula trials, which were conducted between 1993 and 2001, and were able to link 91.2% (1,607) to academic records.
They found “no benefit of the infant formula modifications on cognitive outcomes.”
Three types of formula studied
In this study, the researchers discuss three widely available types of modified infant formulas that have been promoted as benefiting cognitive development: formula enriched with nutrients; formula supplemented with long-chain polyunsaturated fatty acids (LCPUFAs); and follow-on formula fortified with iron.
In one supplement group the academic results were worse than for those given standard formula. At age 11, children who had been given the LCPUFA-enhanced formula scored lower in both English and math.
“Given the potential associations between the source of LCPUFAs and adverse cognitive outcomes, long-term follow-up of trials testing infant formulas from other sources of LCPUFAs is recommended,” the authors wrote.
Nutrients can harm, editorialist says
Charlotte Wright, BM BCH, MSc, a pediatrician and epidemiologist with the Glasgow Royal Hospital for Children in Glasgow, who was not part of the study, coauthored an editorial that accompanied the article in the BMJ.
Dr. Wright and nutritionist Ada L. Gargia, PhD, at the University of Glasgow, wrote that nutrients in some formula enhancements can harm and that infant milk trials often have been poorly conducted.
The editorialists point to a large systematic review of formula milk trials published this year in the BMJ by Helfer et al. that found that most were funded by industry.
“Helfer and colleagues’ review found that 80% of studies were at high risk of bias, mainly because of selective reporting, with 92% of abstracts mentioning positive findings, despite only 42% of trials finding statistically significant differences in a stated primary outcome,” they wrote.
Dr. Wright, who runs a specialist feeding clinic for children, said in an interview that the study is valuable in that it has follow-up “to an age when adult cognition can be robustly assessed.”
She noted that the authors say additives that have been shown to be harmful are still routinely added.
“There is now evidence that adding LCPUFAs results in lower cognition and that giving extra iron to healthy children increases their risk of infection and may even slow their growth,” she said.
But advertisements to the contrary are quickly found in an Internet search, she said, even if no specific claims are made for them.
She gave an example of an advertisement for a commonly used enhanced formula, which reads: “Our formulation contains our highest levels of DHA (Omega 3 LCPs) and is enriched with iron to support normal cognitive development.”
The formula studies were done more than 20 years ago, but Dr. Wright said that does not downplay their relevance.
The basic formulation of the formulas hasn’t changed much, she said, and the additives are still present.
This work was supported by the Economic and Social Research Council UCL, Bloomsbury and East London Doctoral Training Partnership and a Great Ormond Street Hospital Charity Research grant. Full disclosures for all authors are available with the full text of the paper. Dr. Wright and Dr. Garcia declared no relevant financial relationships.

Stress, depression during pregnancy can harm child
New evidence points to the importance of helping mothers with their mental health during pregnancy.
Researchers from the National Institutes of Health in Bethesda, Md., have found that feelings of stress or depression while pregnant are linked to changes in the placenta where the child is growing. The findings, published in Epigenomics, show these changes could alter gene activity.
Stress and depression are not uncommon among expectant women, with depression affecting an estimated 1 in 10 pregnancies, according to the American College of Obstetricians and Gynecologists.
And current evidence already suggests that depression during pregnancy can negatively affect a child later in life. For instance, one study found that depression during pregnancy was linked to behavioral and emotional disorders during childhood, and another found that it raised the risk of depression at age 18.
To investigate stress and depression during pregnancy, the NIH investigators evaluated 301 pregnant women from 12 clinics in the United States who had taken part in an earlier clinical study. The group was ethnically diverse, with 34% identifying as Hispanic, 26% as non-Hispanic White, 24% as non-Hispanic Black, and 17% as Asian or Pacific Islander.
At the start of the study, the women were asked to complete questionnaires routinely used to screen for stress and depression. They completed the questionnaire five more times during their pregnancies. Shortly after each woman gave birth, researchers took tissue samples from the placenta and analyzed the genetics.
The purpose of studying the placenta, according to lead researcher Markos Tesfaye, MD, a postdoctoral fellow at the NIH, is that chemical changes can regulate whether a nearby gene can be activated.
There is evidence that chemical modifications in the placenta can lead to changes in fetal tissues, such as the brain, he said. And the placenta is known for making neurotransmitters, which are needed for fetal brain development.
The team found 16 areas where changes to the exterior of placental DNA were linked to depression in the second or third trimester. They also found two areas where these changes were associated with stress in the third trimester.
“Maternal depression leaves signals in the placenta at genes critical for fetal brain programming,” said study author Fasil Tekola-Ayele, PhD, from the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development.
Two of the chemical changes linked to depression were near genes that are known to be involved with fetal brain development and neurologic and psychiatric illnesses.
“The findings illustrate that the developing fetus is sensitive to the mother›s condition during pregnancy, including maternal symptoms of low mood and perceived stress,” said Thalia K. Robakis, MD, from the women’s mental health program at Icahn School of Medicine at Mount Sinai, New York, who was not involved in the study.
But Dr. Robakis cautioned that no clinical outcomes were measured among the babies born, meaning that the study could not document any effects of maternal depression and stress on fetal development. Rather, the work contributes to figuring out what mechanisms are involved.
“Pregnant women should continue to focus on optimizing their own physical and mental health,” Dr. Robakis said. “And they should know that a happy, healthy mother is the most important factor supporting the development of a happy, healthy baby.”

You’ve been uneasy about the mother’s boyfriend: This may be why
The first patient of the afternoon is a 4-month-old in for his health maintenance visit. You’ve known his 20-year-old mother since she was a toddler. This infant has a 2-year-old sister. Also in the exam room is a young man you don’t recognize whom the mother introduces as Jason, her new boyfriend. He never makes eye contact and despite your best efforts you can’t get him to engage.
At the child’s next visit you are relieved to see the 6-month-old is alive and well and learn that your former patient and her two children have moved back in with her parents and Jason is no longer in the picture.
You don’t have to have been doing pediatrics very long to have learned that a “family” that includes an infant and a young adult male who is probably not the father is an environment in which the infant’s health and well-being is at significant risk. It is a situation in which child abuse even to the point of infanticide should be waving a red flag in your face.
Infanticide occurs in many animal species including our own. As abhorrent we may find the act, it occurs often enough to be, if not normal, at least not unexpected in certain circumstances. Theories abound as to what advantage the act of infanticide might convey to the success of a species. However, little if anything is known about any possible mechanisms that would allow it to occur.
Recently, a professor of molecular and cellular biology at Harvard University discovered a specific set of neurons in the mouse brain that controls aggressive behavior toward infants (Biological triggers for infant abuse, by Juan Siliezar, The Harvard Gazette, Sept 27, 2021). This same set of neurons also appears to trigger avoidance and neglect behaviors as well.
Research in other animal species has found that these antiparental behaviors occur in both virgins and sexually mature males who are strangers to the group. Interestingly, the behaviors switch off once individuals have their own offspring or have had the opportunity to familiarize themselves with infants. Not surprisingly, other studies have found that in some species environmental stress such as food shortage or threats of predation have triggered females to attack or ignore their offspring.
I think it is safe to assume a similar collection of neurons controlling aggressive behavior also exists in humans. One can imagine some well-read defense attorney dredging up this study and claiming that because his client had not yet fathered a child of his own that it was his nervous system’s normal response that made him toss his girlfriend’s baby against the wall.
The lead author of the study intends to study this collection of neurons in more depth to discover more about the process. It is conceivable that with more information her initial findings may help in the development of treatment and specific prevention strategies. Until that happens, we must rely on our intuition and keep our antennae tuned and alert for high-risk scenarios like the one I described at the opening of this letter.
We are left with leaning heavily on our community social work networks to keep close tabs on these high-risk families, offering both financial and emotional support. Parenting classes may be helpful, but some of this research leads me to suspect that immersing these young parents-to-be in hands-on child care situations might provide the best protection we can offer.

He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

The first patient of the afternoon is a 4-month-old in for his health maintenance visit. You’ve known his 20-year-old mother since she was a toddler. This infant has a 2-year-old sister. Also in the exam room is a young man you don’t recognize whom the mother introduces as Jason, her new boyfriend. He never makes eye contact and despite your best efforts you can’t get him to engage.
At the child’s next visit you are relieved to see the 6-month-old is alive and well and learn that your former patient and her two children have moved back in with her parents and Jason is no longer in the picture.
You don’t have to have been doing pediatrics very long to have learned that a “family” that includes an infant and a young adult male who is probably not the father is an environment in which the infant’s health and well-being is at significant risk. It is a situation in which child abuse even to the point of infanticide should be waving a red flag in your face.
Infanticide occurs in many animal species including our own. As abhorrent we may find the act, it occurs often enough to be, if not normal, at least not unexpected in certain circumstances. Theories abound as to what advantage the act of infanticide might convey to the success of a species. However, little if anything is known about any possible mechanisms that would allow it to occur.
Recently, a professor of molecular and cellular biology at Harvard University discovered a specific set of neurons in the mouse brain that controls aggressive behavior toward infants (Biological triggers for infant abuse, by Juan Siliezar, The Harvard Gazette, Sept 27, 2021). This same set of neurons also appears to trigger avoidance and neglect behaviors as well.
Research in other animal species has found that these antiparental behaviors occur in both virgins and sexually mature males who are strangers to the group. Interestingly, the behaviors switch off once individuals have their own offspring or have had the opportunity to familiarize themselves with infants. Not surprisingly, other studies have found that in some species environmental stress such as food shortage or threats of predation have triggered females to attack or ignore their offspring.
I think it is safe to assume a similar collection of neurons controlling aggressive behavior also exists in humans. One can imagine some well-read defense attorney dredging up this study and claiming that because his client had not yet fathered a child of his own that it was his nervous system’s normal response that made him toss his girlfriend’s baby against the wall.
The lead author of the study intends to study this collection of neurons in more depth to discover more about the process. It is conceivable that with more information her initial findings may help in the development of treatment and specific prevention strategies. Until that happens, we must rely on our intuition and keep our antennae tuned and alert for high-risk scenarios like the one I described at the opening of this letter.
We are left with leaning heavily on our community social work networks to keep close tabs on these high-risk families, offering both financial and emotional support. Parenting classes may be helpful, but some of this research leads me to suspect that immersing these young parents-to-be in hands-on child care situations might provide the best protection we can offer.

Maternal SSRI use linked to more encephalopathy in newborns, risk still small
, although the overall risk remains extremely low, a new study finds.
The findings were presented in a poster at the 50th annual meeting of the Child Neurology Society.
“Our work showed that neonates exposed to SSRI in utero had higher risks of neonatal encephalopathy even when adjusting for confounders such as maternal mental health disorders and age. SSRIs could cause side effects such as encephalopathy in neonates, and these risks need to be balanced carefully with the potential benefits of treatment to the mother,” study lead author Marie Cornet, MD, a neonatology fellow with Benioff Children’s Hospital at the University of California, San Francisco, said in an interview.
According to Dr. Cornet, “we know that SSRI exposure in utero is associated with increased risks of respiratory distress at birth, need for positive-pressure ventilation, and an abnormal neurologic exam.” The researchers launched the new study to determine if the estimated 4%-8% of pregnant women who take SSRIs may be putting their newborns at greater risk of NE.
The researchers retrospectively tracked 305,426 infants who were born in the Kaiser Permanente Northern California health system (≥35 weeks) from 2011 to 2019. The mothers had an average age of 31 years, and approximately 34.7% were White, 34.7% of unknown race, 23.3% Asian, and 6.2% Black.
The researchers defined NE as a “5-minute APGAR score <7 and abnormal level of consciousness, activity, tone, or reflexes.”
A total of 8,024 infants (2.6%) had mothers who used SSRIs in the third trimester, and 510 (0.17%) were determined to have had NE.
After adjustment for maternal depression or anxiety, maternal age, race, and hospital, exposed neonates had 2.7 times higher odds of NE (odds ratio, 2.7).
Each 25 mg per day increase in the dose of SSRIs, as equalized to doses of sertraline (Zoloft), was linked to a significant 31% increase in the odds of developing NE (OR, 1.31).
The study doesn’t examine the benefits of SSRI treatment in pregnancy. Those taking SSRIs were much more likely to have depression during pregnancy (76.5% vs. 13.5%) and anxiety (56.7% vs. 6.9%), compared with those who did not take the drug.
The possible connection between SSRIs and NE is unclear. “SSRIs may contribute to NE by a withdrawal mechanism or by a toxicity mechanism. It is also possible that SSRIs themselves are not responsible for encephalopathy, or that the severity of maternal mental health is itself responsible for increased neonatal encephalopathy,” Dr. Cornet said. “However, we believe we adjusted our results thoroughly for that. Furthermore, in this cohort, neonates born from mothers with untreated depression were not at higher risk of encephalopathy than neonates born to mothers without depression.”
She added: “When infants have acidosis or require prolonged resuscitation after birth, they get treated with therapeutic hypothermia. This invasive treatment was shown to decrease mortality and morbidity in neonates with hypoxic-ischemic encephalopathy. However, therapeutic hypothermia may not be helpful in infants with encephalopathy due to other causes than acute hypoxia-ischemia, such as infection, inflammation, genetic conditions, or exposure to toxins. In the case of SSRIs, our results show that, while neonates often have encephalopathy, this encephalopathy is often mild and self-resolved. We did not see a statistically significant increase in acidosis or treatment with therapeutic hypothermia.”
In the future neurologists should consider SSRI use as a potential cause in cases of NE, Dr. Cornet said. “If there are no signs of hypoxic-ischemic encephalopathy – no evidence of acidosis, acute perinatal event – treatment with therapeutic hypothermia may not be indicated.”
Dr. Cornet said more research is in the works. “Studying the long-term side effect of SSRIs on neonatal brain development and injury is essential,” she said. “We plan to compare brain injury in neonates exposed and unexposed to SSRIs and examine long-term outcomes to assess if the effect of SSRI exposure is transient or has a lasting impact.”
This study was funded by the Thrasher Early Career Research Grant and by the Newborn Brain Research Innovation Award at UCSF. The authors have no relevant disclosures.

COVID-19 vaccines in pregnancy may protect baby, too
Women who receive COVID-19 vaccines during pregnancy pass antibodies to their babies, which could protect newborns from the disease, research has shown.
Researchers with New York University Langone Health conducted a study that included pregnant women who had received at least one dose of an mRNA COVID-19 vaccine (Pfizer/BioNTech or Moderna) by June 4.
All neonates had antibodies to the spike protein at high titers, the researchers found.
Unlike similar prior studies, the researchers also looked for antibodies to the nucleocapsid protein, which would have indicated the presence of antibodies from natural COVID-19 infection. They did not detect antibodies to the nucleocapsid protein, and the lack of these antibodies suggests that the antibodies to the spike protein resulted from vaccination and not from prior infection, the researchers said.
The participants had a median time from completion of the vaccine series to delivery of 13 weeks. The study was published online in the American Journal of Obstetrics & Gynecology MFM.
“The presence of these anti-spike antibodies in the cord blood should, at least in theory, offer these newborns some degree of protection,” said study investigator Ashley S. Roman, MD, director of the division of maternal-fetal medicine at NYU Langone Health. “While the primary rationale for vaccination during pregnancy is to keep moms healthy and keep moms out of the hospital, the outstanding question to us was whether there is any fetal or neonatal benefit conferred by receiving the vaccine during pregnancy.”
Questions remain about the degree and durability of protection for newborns from these antibodies. An ongoing study, MOMI-VAX, aims to systematically measure antibody levels in mothers who receive COVID-19 vaccines during pregnancy and in their babies over time.
The present study contributes welcome preliminary evidence suggesting a benefit to infants, said Emily Adhikari, MD, of the University of Texas Southwestern Medical Center in Dallas, who was not involved in the study.
Still, “the main concern and our priority as obstetricians is to vaccinate pregnant women to protect them from severe or critical illness,” she said.
Although most individuals infected with SARS-CoV-2 recover, a significant portion of pregnant women get seriously sick, Dr. Adhikari said. “With this recent Delta surge, we are seeing more pregnant patients who are sicker,” said Dr. Adhikari, who has published research from one hospital describing this trend.
When weighing whether patients should receive COVID-19 vaccines in pregnancy, the risks from infection have outweighed any risk from vaccination to such an extent that there is “not a comparison to make,” Dr. Adhikari said. “The risks of the infection are so much higher.
“For me, it is a matter of making sure that my patient understands that we have really good safety data on these vaccines and there is no reason to think that a pregnant person would be harmed by them. On the contrary, the benefit is to protect and maybe even save your life,” Dr. Adhikari said. “And now we have more evidence that the fetus may also benefit.”
The rationale for vaccinations during pregnancy can vary, Dr. Roman said. Flu shots in pregnancy mainly are intended to protect the mother, though they confer protection for newborns as well. With the whooping cough vaccine given in the third trimester, however, the primary aim is to protect the baby from whooping cough in the first months of life, Dr. Roman said.
“I think it is really important for pregnant women to understand that antibodies crossing the placenta is a good thing,” she added.
As patients who already have received COVID-19 vaccines become pregnant and may become eligible for a booster dose, Dr. Adhikari will offer it, she said, though she has confidence in the protection provided by the initial immune response.

COVID-19 linked to baby bust in high-income countries
In an assessment of the pandemic’s early effects, Arnstein Aassve, PhD, and colleagues found a significant COVID-19–related decline in crude birth rates (CBRs) in 7 of 22 high-income countries, particularly in Southwestern Europe.
Dr. Aassve, an economist at the Carlo F. Dondena Center for Research on Social Dynamics and Public Policy at the Università Commerciale Luigi Bocconi, Milan, and colleagues report the results in an article published online August 30 in the Proceedings of the National Academy of Sciences.
Defining the start of the COVID-19 pandemic as February 2020, the study identifies strong declines in Italy (-9.1%), Hungary (-8.5%), Spain (-8.4%), and Portugal (-6.6%) beyond those predicted by past trends. In the United States, CBRs fell by 7.1% relative to 2019 for births occurring in Nov. and Dec. 2020 following conceptions in February and March of that year.
Significant declines in CBR also occurred in Belgium, Austria, and Singapore.
A year-to-year comparison of the mean for monthly CBRs per 1,000 population before and during the pandemic suggests a negative difference for all countries studied except for Denmark, Finland, Germany, and the Netherlands, Dr. Aassve and colleagues write. These findings may have policy implications for childcare, housing, and the labor market.
The Milan researchers compared monthly vital statistics data on live births from the international Human Fertility Database for the period of Jan. 2016 to March 2021. These figures reflect conceptions carried to term between April 2015 and June 2020. The 22 countries in the analysis represent 37% of the total reported COVID-19 cases and 34% of deaths worldwide.
The study findings align with surveys on “fertility intentions” collected early in the first COVID-19 wave in Germany, France, Spain, and the United Kingdom. These surveys indicated that 73% of people who were planning pregnancies in 2020 either decided to delay the pregnancy or they abandoned their plans.
“The popular media speculated that the lockdown would lead to a baby boom, as couples spent more time together,” Dr. Aassve told this news organization. “There’s very little evidence of this when you look to previous disasters and shocks, and the first data suggest more of an immediate collapse than a boom. But as you also see from the paper, the collapse is not seen everywhere.” Other current studies suggest the fertility drop is immediate but temporary, says Dr. Aassve, who is also a professor of demography.
Interestingly, Dr. Aassve and colleagues found that CBRs were relatively stable in Northern Europe. The authors point to supportive social and family policies in that region that might have reduced the effect of the pandemic on births. “These factors are likely to affect CBRs in the subsequent pandemic waves,” they write. They call for future studies to assess the full population implications of the pandemic, the moderating impact of policy interventions, and the nexus between short- and long-run effects in relation to the various waves of the COVID-19 pandemic.
Rebounds
Some regions have already reported a rebound from the COVID-19 fertility trough. Molly J. Stout, MD, director of maternal fetal medicine at the University of Michigan, Ann Arbor, and colleagues used electronic medical records to predict a surge in births after the initial decline.
“The surge we’ve seen at the end of this summer is exceeding the usual annual birth rate, as predicted,” she said in an interview. “But I think there’ll be a return to normal after this transient escalation. I don’t think birth rates will stay elevated above the normal because the birth surge is a temporary response to an event, although there will likely be regional differences.”
Looking ahead, Dr. Stout, who was not involved in Dr. Aassve’s analysis, is not certain how a fourth pandemic wave might ultimately modify a couple’s overall family size. But the toll the health crisis has taken on working women who have been forced to withdraw from the economy because of a lack of childcare points to a societal need that should be addressed.
According to Philip N. Cohen, PhD, a professor of sociology at the University of Maryland, College Park, who’s been tracking fertility trends since the onset of the COVID-19 emergency, the pandemic has combined a health crisis with an economic crisis, along with “the additional factor of social distancing and isolation, which all contributed to the decline in birth rates. Some people changed their plans to hold off on having children, while others didn’t get pregnant because they weren’t socializing and meeting people as much.”
Dr. Cohen, who was not involved in the study by Dr. Aassve and associates, said his provisional data show that although in many places, birth rates have rebounded more or less to prepandemic levels after a nadir around Jan. 2021, some areas of the United States still show substantially lower rates, including California, Hawaii, and Oregon.
As to the duration of the pandemic effect, Dr. Aassve cautions that his group’s estimates refer to the first wave only. “We then have the second, third, and currently the fourth wave. We can’t be sure about the impact of these waves on fertility since the data are not there yet, but I’d be surprised if they didn’t continue to have an impact on fertility rates,” he said.
Dr. Cohen agreed: “Some people who delayed childbearing will make up the delay. However, whenever there’s a delay, there’s inevitably some portion of the decline that’s not recouped.”
As for the wider effect across the world, Dr. Aassve said his team’s figures derive from high-income countries where data are readily available. For middle- and low-income countries, fewer data exist, and the quality of those data is not as good.
The lessons from this and other upheavals teach us that unforeseen shocks almost always have a negative impact on fertility, says Dr. Aassve. “[B]ut these effects may be separate from existing declining trends. The issue here is that those overall declining trends may be driven by other factors. In contrast, the shock of the pandemic is short-lived, and we may return to normal rather quickly. But if the pandemic also impacts other societal structures, such as the occupational and industrial sectors, then the pandemic might exacerbate the negative trend.”

In an assessment of the pandemic’s early effects, Arnstein Aassve, PhD, and colleagues found a significant COVID-19–related decline in crude birth rates (CBRs) in 7 of 22 high-income countries, particularly in Southwestern Europe.
Dr. Aassve, an economist at the Carlo F. Dondena Center for Research on Social Dynamics and Public Policy at the Università Commerciale Luigi Bocconi, Milan, and colleagues report the results in an article published online August 30 in the Proceedings of the National Academy of Sciences.
Defining the start of the COVID-19 pandemic as February 2020, the study identifies strong declines in Italy (-9.1%), Hungary (-8.5%), Spain (-8.4%), and Portugal (-6.6%) beyond those predicted by past trends. In the United States, CBRs fell by 7.1% relative to 2019 for births occurring in Nov. and Dec. 2020 following conceptions in February and March of that year.
Significant declines in CBR also occurred in Belgium, Austria, and Singapore.
A year-to-year comparison of the mean for monthly CBRs per 1,000 population before and during the pandemic suggests a negative difference for all countries studied except for Denmark, Finland, Germany, and the Netherlands, Dr. Aassve and colleagues write. These findings may have policy implications for childcare, housing, and the labor market.
The Milan researchers compared monthly vital statistics data on live births from the international Human Fertility Database for the period of Jan. 2016 to March 2021. These figures reflect conceptions carried to term between April 2015 and June 2020. The 22 countries in the analysis represent 37% of the total reported COVID-19 cases and 34% of deaths worldwide.
The study findings align with surveys on “fertility intentions” collected early in the first COVID-19 wave in Germany, France, Spain, and the United Kingdom. These surveys indicated that 73% of people who were planning pregnancies in 2020 either decided to delay the pregnancy or they abandoned their plans.
“The popular media speculated that the lockdown would lead to a baby boom, as couples spent more time together,” Dr. Aassve told this news organization. “There’s very little evidence of this when you look to previous disasters and shocks, and the first data suggest more of an immediate collapse than a boom. But as you also see from the paper, the collapse is not seen everywhere.” Other current studies suggest the fertility drop is immediate but temporary, says Dr. Aassve, who is also a professor of demography.
Interestingly, Dr. Aassve and colleagues found that CBRs were relatively stable in Northern Europe. The authors point to supportive social and family policies in that region that might have reduced the effect of the pandemic on births. “These factors are likely to affect CBRs in the subsequent pandemic waves,” they write. They call for future studies to assess the full population implications of the pandemic, the moderating impact of policy interventions, and the nexus between short- and long-run effects in relation to the various waves of the COVID-19 pandemic.
Rebounds
Some regions have already reported a rebound from the COVID-19 fertility trough. Molly J. Stout, MD, director of maternal fetal medicine at the University of Michigan, Ann Arbor, and colleagues used electronic medical records to predict a surge in births after the initial decline.
“The surge we’ve seen at the end of this summer is exceeding the usual annual birth rate, as predicted,” she said in an interview. “But I think there’ll be a return to normal after this transient escalation. I don’t think birth rates will stay elevated above the normal because the birth surge is a temporary response to an event, although there will likely be regional differences.”
Looking ahead, Dr. Stout, who was not involved in Dr. Aassve’s analysis, is not certain how a fourth pandemic wave might ultimately modify a couple’s overall family size. But the toll the health crisis has taken on working women who have been forced to withdraw from the economy because of a lack of childcare points to a societal need that should be addressed.

‘Reassuring’ findings for second-generation antipsychotics during pregnancy
Second-generation antipsychotics (SGAs) taken by pregnant women are linked to a low rate of adverse effects in their children, new research suggests.
Data from a large registry study of almost 2,000 women showed that 2.5% of the live births in a group that had been exposed to antipsychotics had confirmed major malformations compared with 2% of the live births in a non-exposed group. This translated into an estimated odds ratio of 1.5 for major malformations.
“The 2.5% absolute risk for major malformations is consistent with the estimates of the Centers for Disease Control and Prevention’s national baseline rate of major malformations in the general population,” lead author Adele Viguera, MD, MPH, director of research for women’s mental health, Cleveland Clinic Neurological Institute, told this news organization.
“Our results are reassuring and suggest that second-generation antipsychotics, as a class, do not substantially increase the risk of major malformations,” Dr. Viguera said.
The findings were published online August 3 in the Journal of Clinical Psychiatry.
Safety data scarce
Despite the increasing use of SGAs to treat a “spectrum of psychiatric disorders,” relatively little data are available on the reproductive safety of these agents, Dr. Viguera said.
The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) was established in 2008 to determine risk for major malformation among infants exposed to these medications during the first trimester, relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity.
The NPRAA follows pregnant women (aged 18 to 45 years) with psychiatric illness who are exposed or unexposed to SGAs during pregnancy. Participants are recruited through nationwide provider referral, self-referral, and advertisement through the Massachusetts General Hospital Center for Women’s Mental Health website.
Specific data collected are shown in the following table.
Since publication of the first results in 2015, the sample size for the trial has increased – and the absolute and relative risk for major malformations observed in the study population are “more precise,” the investigators note. The current study presented updated previous findings.
Demographic differences
Of the 1,906 women who enrolled as of April 2020, 1,311 (mean age, 32.6 years; 81.3% White) completed the study and were eligible for inclusion in the analysis.
Although the groups had a virtually identical mean age, fewer women in the exposure group were married compared with those in the non-exposure group (77% vs. 90%, respectively) and fewer had a college education (71.2% vs. 87.8%). There was also a higher percentage of first-trimester cigarette smokers in the exposure group (18.4% vs. 5.1%).
On the other hand, more women in the non-exposure group used alcohol than in the exposure group (28.6% vs. 21.4%, respectively).
The most frequent psychiatric disorder in the exposure group was bipolar disorder (63.9%), followed by major depression (12.9%), anxiety (5.8%), and schizophrenia (4.5%). Only 11.4% of women in the non-exposure group were diagnosed with bipolar disorder, whereas 34.1% were diagnosed with major depression, 31.3% with anxiety, and none with schizophrenia.
Notably, a large percentage of women in both groups had a history of postpartum depression and/or psychosis (41.4% and 35.5%, respectively).
The most frequently used SGAs in the exposure group were quetiapine (Seroquel), aripiprazole (Abilify), and lurasidone (Latuda).
Participants in the exposure group had a higher age at initial onset of primary psychiatric diagnosis and a lower proportion of lifetime illness compared with those in the non-exposure group.
Major clinical implication?
Among 640 live births in the exposure group, which included 17 twin pregnancies and 1 triplet pregnancy, 2.5% reported major malformations. Among 704 live births in the control group, which included 14 twin pregnancies, 1.99% reported major malformations.
The estimated OR for major malformations comparing exposed and unexposed infants was 1.48 (95% confidence interval, 0.625-3.517).
The authors note that their findings were consistent with one of the largest studies to date, which included a nationwide sample of more than 1 million women. Its results showed that, among infants exposed to SGAs versus those who were not exposed, the estimated risk ratio after adjusting for psychiatric conditions was 1.05 (95% CI, 0.96-1.16).
Additionally, “a hallmark of a teratogen is that it tends to cause a specific type or pattern of malformations, and we found no preponderance of one single type of major malformation or specific pattern of malformations among the exposed and unexposed groups,” Dr. Viguera said
“A major clinical implication of these findings is that for women with major mood and/or psychotic disorders, treatment with an atypical antipsychotic during pregnancy may be the most prudent clinical decision, much as continued treatment is recommended for pregnant women with other serious and chronic medical conditions, such as epilepsy,” she added.
The concept of ‘satisficing’
Commenting on the study, Vivien Burt, MD, PhD, founder and director/consultant of the Women’s Life Center at the Resnick University of California, Los Angeles (UCLA) Neuropsychiatric Hospital, called the findings “reassuring.”
The results “support the conclusion that in pregnant women with serious psychiatric illnesses, the use of SGAs is often a better option than avoiding these medications and exposing both the women and their offspring to the adverse consequences of maternal mental illness,” she said.
An accompanying editorial co-authored by Dr. Burt and colleague Sonya Rasminsky, MD, introduced the concept of “satisficing” – a term coined by Herbert Simon, a behavioral economist and Nobel Laureate. “Satisficing” is a “decision-making strategy that aims for a satisfactory (‘good enough’) outcome rather than a perfect one.”
The concept applies to decision-making beyond the field of economics “and is critical to how physicians help patients make decisions when they are faced with multiple treatment options,” said Dr. Burt, a professor emeritus of psychiatry at UCLA.
“The goal of ‘satisficing’ is to plan for the most satisfactory outcome, knowing that there are always unknowns, so in an uncertain world, clinicians should carefully help their patients make decisions that will allow them to achieve an outcome they can best live with,” she noted.
The investigators note that their findings may not be generalizable to the larger population of women taking SGAs, given that their participants were “overwhelmingly White, married, and well-educated women.”
They add that enrollment into the NPRAA registry is ongoing and larger sample sizes will “further narrow the confidence interval around the risk estimates and allow for adjustment of likely sources of confounding.”
The NPRAA is supported by Alkermes, Johnson & Johnson/Janssen Pharmaceuticals, Otsuka America Pharmaceutical, Sunovion Pharmaceuticals, SAGE Therapeutics, Teva Pharmaceuticals, and Aurobindo Pharma. Past sponsors of the NPRAA are listed in the original paper. Dr. Viguera receives research support from the NPRAA, Alkermes Biopharmaceuticals, Aurobindo Pharma, Janssen Pharmaceuticals, Otsuka Pharmaceutical, Sunovion Pharmaceuticals, Teva Pharmaceuticals, and SAGE Therapeutics and receives adviser/consulting fees from Up-to-Date. Dr. Burt has been a consultant/speaker for Sage Therapeutics. Dr. Rasminsky has disclosed no relevant financial relationships.

Additionally, “a hallmark of a teratogen is that it tends to cause a specific type or pattern of malformations, and we found no preponderance of one single type of major malformation or specific pattern of malformations among the exposed and unexposed groups,” Dr. Viguera said
“A major clinical implication of these findings is that for women with major mood and/or psychotic disorders, treatment with an atypical antipsychotic during pregnancy may be the most prudent clinical decision, much as continued treatment is recommended for pregnant women with other serious and chronic medical conditions, such as epilepsy,” she added.
The concept of ‘satisficing’
Commenting on the study, Vivien Burt, MD, PhD, founder and director/consultant of the Women’s Life Center at the Resnick University of California, Los Angeles (UCLA) Neuropsychiatric Hospital, called the findings “reassuring.”
The results “support the conclusion that in pregnant women with serious psychiatric illnesses, the use of SGAs is often a better option than avoiding these medications and exposing both the women and their offspring to the adverse consequences of maternal mental illness,” she said.
An accompanying editorial co-authored by Dr. Burt and colleague Sonya Rasminsky, MD, introduced the concept of “satisficing” – a term coined by Herbert Simon, a behavioral economist and Nobel Laureate. “Satisficing” is a “decision-making strategy that aims for a satisfactory (‘good enough’) outcome rather than a perfect one.”
The concept applies to decision-making beyond the field of economics “and is critical to how physicians help patients make decisions when they are faced with multiple treatment options,” said Dr. Burt, a professor emeritus of psychiatry at UCLA.
“The goal of ‘satisficing’ is to plan for the most satisfactory outcome, knowing that there are always unknowns, so in an uncertain world, clinicians should carefully help their patients make decisions that will allow them to achieve an outcome they can best live with,” she noted.
The investigators note that their findings may not be generalizable to the larger population of women taking SGAs, given that their participants were “overwhelmingly White, married, and well-educated women.”
They add that enrollment into the NPRAA registry is ongoing and larger sample sizes will “further narrow the confidence interval around the risk estimates and allow for adjustment of likely sources of confounding.”

Febrile infant guideline allows wiggle room on hospital admission, testing
The long-anticipated American Academy of Pediatrics guidelines for the treatment of well-appearing febrile infants have arrived, and key points include updated guidance for cerebrospinal fluid testing and urine cultures, according to Robert Pantell, MD, and Kenneth Roberts, MD, who presented the guidelines at the virtual Pediatric Hospital Medicine annual conference.
The AAP guideline was published in the August 2021 issue of Pediatrics. The guideline includes 21 key action statements and 40 total recommendations, and describes separate management algorithms for three age groups: infants aged 8-21 days, 22-28 days, and 29-60 days.
Dr. Roberts, of the University of North Carolina at Chapel Hill, and Dr. Pantell, of the University of California, San Francisco, emphasized that all pediatricians should read the full guideline, but they offered an overview of some of the notable points.
Some changes that drove the development of evidence-based guideline included changes in technology, such as the increased use of procalcitonin, the development of large research networks for studies of sufficient size, and a need to reduce the costs of unnecessary care and unnecessary trauma for infants, Dr. Roberts said. Use of data from large networks such as the Pediatric Emergency Care Applied Research Network provided enough evidence to support dividing the aged 8- to 60-day population into three groups.
The guideline applies to well-appearing term infants aged 8-60 days and at least 37 weeks’ gestation, with fever of 38° C (100.4° F) or higher in the past 24 hours in the home or clinical setting. The decision to exclude infants in the first week of life from the guideline was because at this age, infants “are sufficiently different in rates and types of illness, including early-onset bacterial infection,” according to the authors.
Dr. Roberts emphasized that the guidelines apply to “well-appearing infants,” which is not always obvious. “If a clinician is not confident an infant is well appearing, the clinical practice guideline should not be applied,” he said.
The guideline also includes a visual algorithm for each age group.
Dr. Pantell summarized the key action statements for the three age groups, and encouraged pediatricians to review the visual algorithms and footnotes available in the full text of the guideline.
The guideline includes seven key action statements for each of the three age groups. Four of these address evaluations, using urine, blood culture, inflammatory markers (IM), and cerebrospinal fluid (CSF). One action statement focuses on initial treatment, and two on management: hospital admission versus monitoring at home, and treatment cessation.
Infants aged 8-21 days
The key action statements for well-appearing infants aged 8-21 days are similar to what clinicians likely would do for ill-appearing infants, the authors noted, based in part on the challenge of assessing an infant this age as “well appearing,” because they don’t yet have the ability to interact with the clinician.
For the 8- to 21-day group, the first two key actions are to obtain a urine specimen and blood culture, Dr. Pantell said. Also, clinicians “should” obtain a CSF for analysis and culture. “We recognize that the ability to get CSF quickly is a challenge,” he added. However, for the 8- to 21-day age group, a new feature is that these infants may be discharged if the CSF is negative. Evaluation in this youngest group states that clinicians “may assess inflammatory markers” including height of fever, absolute neutrophil count, C-reactive protein, and procalcitonin.
Treatment of infants in the 8- to 21-day group “should” include parenteral antimicrobial therapy, according to the guideline, and these infants “should” be actively monitored in the hospital by nurses and staff experienced in neonatal care, Dr. Pantell said. The guideline also includes a key action statement to stop antimicrobials at 24-36 hours if cultures are negative, but to treat identified organisms.
Infants aged 22-28 days
In both the 22- to 28-day-old and 29- to 60-day-old groups, the guideline offers opportunities for less testing and treatment, such as avoiding a lumbar puncture, and fewer hospitalizations. The development of a separate guideline for the 22- to 28-day group is something new, said Dr. Pantell. The guideline states that clinicians should obtain urine specimens and blood culture, and should assess IM in this group. Further key action statements note that clinicians “should obtain a CSF if any IM is positive,” but “may” obtain CSF if the infant is hospitalized, if blood and urine cultures have been obtained, and if none of the IMs are abnormal.
As with younger patients, those with a negative CSF can go home, he said. As for treatment, clinicians “should” administer parenteral antimicrobial therapy to infants managed at home even if they have a negative CSF and urinalysis (UA), and no abnormal inflammatory markers Other points for management of infants in this age group at home include verbal teaching and written instructions for caregivers, plans for a re-evaluation at home in 24 hours, and a plan for communication and access to emergency care in case of a change in clinical status, Dr. Pantell explained. The guideline states that infants “should” be hospitalized if CSF is either not obtained or not interpretable, which leaves room for clinical judgment and individual circumstances. Antimicrobials “should” be discontinued in this group once all cultures are negative after 24-36 hours and no other infection requires treatment.
Infants aged 29-60 days
For the 29- to 60-day group, there are some differences, the main one is the recommendation of blood cultures in this group, said Dr. Pantell. “We are seeing a lot of UTIs [urinary tract infections], and we would like those treated.” However, clinicians need not obtain a CSF if other IMs are normal, but may do so if any IM is abnormal. Antimicrobial therapy may include ceftriaxone or cephalexin for UTIs, or vancomycin for bacteremia.
Although antimicrobial therapy is an option for UTIs and bacterial meningitis, clinicians “need not” use antimicrobials if CSF is normal, if UA is negative, and if no IMs are abnormal, Dr. Pantell added. Overall, further management of infants in this oldest age group should focus on discharge to home in the absence of abnormal findings, but hospitalization in the presence of abnormal CSF, IMs, or other concerns.
During a question-and-answer session, Dr. Roberts said that, while rectal temperature is preferable, any method is acceptable as a starting point for applying the guideline. Importantly, the guideline still leaves room for clinical judgment. “We hope this will change some thinking as far as whether one model fits all,” he noted. The authors tried to temper the word “should” with the word “may” when possible, so clinicians can say: “I’m going to individualize my decision to the infant in front of me.”
Ultimately, the guideline is meant as a guide, and not an absolute standard of care, the authors said. The language of the key action statements includes the words “should, may, need not” in place of “must, must not.” The guideline recommends factoring family values and preferences into any treatment decisions. “Variations, taking into account individual circumstances, may be appropriate.”
The guideline received no outside funding. The authors had no financial conflicts to disclose.

Does early delivery for FGR affect school outcomes?
Iatrogenic delivery for suspected fetal growth restriction (FGR) may be associated with an increased likelihood of poorer school outcomes among infants born severely small for gestational age, a study of children in Australia suggests.
reported in JAMA.
“It raises the question: in our efforts to improve outcomes in babies that are small, are we potentially doing more harm than good?” said Robert M. Silver, MD, of the department of obstetrics and gynecology at the University of Utah, Salt Lake City, who was not involved in the study. “I think that is a very important question to ask.”
However, “we can’t make that conclusion based on this one study,” he said in an interview. It could be that, in cases where severely small infants were delivered early, there may have been testing that indicated acute risks, and these infants may have tended to be sicker overall. “It may have been that if those babies weren’t delivered, they would have suffered a stillbirth or major brain injury,” Dr. Silver said. “It is really important that we acknowledge that we shouldn’t change our clinical practice” based on this one study.”
At the same time, the study underscores questions and challenges that surround the definition, identification, and management of suspected FGR, Dr. Silver said.
The study authors described their research as exploratory. In a related editorial Dr. Silver and Nathan R. Blue, MD said the findings should be considered hypothesis generating.
For the study, Roshan John Selvaratnam, BMedSc(Hons), a researcher affiliated with Monash University, Melbourne, and colleagues analyzed data from 181,902 children with developmental outcomes and 425,717 children with educational outcomes in Australia. They included children born at 32 weeks’ or more gestation between 2003 and 2013.
Severely small infants delivered early for suspected FGR had an average gestation of 37.9 weeks, whereas those not suspected of having FGR had an average gestation of 39.4 weeks.
Among infants who were severely small for gestational age, those delivered early for suspected FGR were more likely to be in the bottom 10th percentile on at least two developmental domains when they started school, compared with those not suspected of having FGR (16.2% vs. 12.7%; adjusted odds ratio, 1.36). They also were more likely to have low test scores in subsequent years. In grade 7, for example, the adjusted odds ratio for scoring below the national minimum standard on at least two educational domains was 1.33 (13.4% vs. 10.5%).
The researchers defined severely small for gestational age as birth weight below the third percentile. Among infants with normal growth, defined as birth weight at the 10th percentile or greater, school outcomes did not significantly differ between those with early delivery for suspected FGR and those not suspected of having FGR. Approximately 8% of the infants with normal growth had poor developmental outcomes.
The study authors described the dilemma that clinicians face with suspected FGR: “Either intervene early to prevent a small risk of stillbirth but potentially cause immediate and lifelong harm to the child or accept the increasing risk of stillbirth associated with prolonging the pregnancy to avoid more common neonatal and longer-term morbidities.”
It could be that severely small infants with suspected FGR in the study were “more compromised than those not suspected of having FGR,” which might explain the outcomes, Mr. Selvaratnam and coauthors wrote.
Another more plausible explanation is that “iatrogenic prematurity was harmful,” they said.
The researchers were unable to adjust for many factors that may influence academic success, including smoking and alcohol use during pregnancy, maternal body mass index, and breastfeeding, they noted. They also lacked information about the etiology for FGR and whether children had genetic abnormalities.
The study also does not take into account neonatal, infant, and childhood complications, Dr. Silver and Dr. Blue wrote in their editorial. “Nonetheless, these data are a welcome contribution given the knowledge gaps with regard to the optimal obstetric management of FGR.”
The establishment of a diagnostic standard for FGR is needed to properly investigate ways to improve risk stratification, diagnosis, and management, Dr. Silver and Dr. Blue added.
“What we have to do is get better at predicting which babies are at very high risk for continuing the pregnancy and which babies are at low risk for continuing the pregnancy so that we can better decide which babies would benefit from slightly early delivery,” Dr. Silver said.
Improved detection and management of FGR may be on the horizon. “Our ability to image the placental function has gotten a lot better, and I think that is really going to help us,” Dr. Silver said. Studies that aim to further improve the ability to assess whether babies are getting adequate blood flow during pregnancy are ongoing, which could further help doctors evaluate risks.
The study investigators and Dr. Silver had no conflict of interest disclosures. Dr. Blue disclosed grants from Samsung Medison and personal fees from Elsevier. The study was supported by a grant from the Australian government’s National Health and Medical Research Council Program, and Mr. Selvaratnam is supported by scholarships from an Australian government research training program and the National Centre of Research Excellence in Stillbirth.

Silver, MD, of the department of obstetrics and gynecology at the University of Utah, Salt Lake City, who was not involved in the study. “I think that is a very important question to ask.”
However, “we can’t make that conclusion based on this one study,” he said in an interview. It could be that, in cases where severely small infants were delivered early, there may have been testing that indicated acute risks, and these infants may have tended to be sicker overall. “It may have been that if those babies weren’t delivered, they would have suffered a stillbirth or major brain injury,” Dr. Silver said. “It is really important that we acknowledge that we shouldn’t change our clinical practice” based on this one study.”
At the same time, the study underscores questions and challenges that surround the definition, identification, and management of suspected FGR, Dr. Silver said.
The study authors described their research as exploratory. In a related editorial Dr. Silver and Nathan R. Blue, MD said the findings should be considered hypothesis generating.
For the study, Roshan John Selvaratnam, BMedSc(Hons), a researcher affiliated with Monash University, Melbourne, and colleagues analyzed data from 181,902 children with developmental outcomes and 425,717 children with educational outcomes in Australia. They included children born at 32 weeks’ or more gestation between 2003 and 2013.
Severely small infants delivered early for suspected FGR had an average gestation of 37.9 weeks, whereas those not suspected of having FGR had an average gestation of 39.4 weeks.
Among infants who were severely small for gestational age, those delivered early for suspected FGR were more likely to be in the bottom 10th percentile on at least two developmental domains when they started school, compared with those not suspected of having FGR (16.2% vs. 12.7%; adjusted odds ratio, 1.36). They also were more likely to have low test scores in subsequent years. In grade 7, for example, the adjusted odds ratio for scoring below the national minimum standard on at least two educational domains was 1.33 (13.4% vs. 10.5%).
The researchers defined severely small for gestational age as birth weight below the third percentile. Among infants with normal growth, defined as birth weight at the 10th percentile or greater, school outcomes did not significantly differ between those with early delivery for suspected FGR and those not suspected of having FGR. Approximately 8% of the infants with normal growth had poor developmental outcomes.
The study authors described the dilemma that clinicians face with suspected FGR: “Either intervene early to prevent a small risk of stillbirth but potentially cause immediate and lifelong harm to the child or accept the increasing risk of stillbirth associated with prolonging the pregnancy to avoid more common neonatal and longer-term morbidities.”
It could be that severely small infants with suspected FGR in the study were “more compromised than those not suspected of having FGR,” which might explain the outcomes, Mr. Selvaratnam and coauthors wrote.
Another more plausible explanation is that “iatrogenic prematurity was harmful,” they said.
The researchers were unable to adjust for many factors that may influence academic success, including smoking and alcohol use during pregnancy, maternal body mass index, and breastfeeding, they noted. They also lacked information about the etiology for FGR and whether children had genetic abnormalities.
The study also does not take into account neonatal, infant, and childhood complications, Dr. Silver and Dr. Blue wrote in their editorial. “Nonetheless, these data are a welcome contribution given the knowledge gaps with regard to the optimal obstetric management of FGR.”
The establishment of a diagnostic standard for FGR is needed to properly investigate ways to improve risk stratification, diagnosis, and management, Dr. Silver and Dr. Blue added.
“What we have to do is get better at predicting which babies are at very high risk for continuing the pregnancy and which babies are at low risk for continuing the pregnancy so that we can better decide which babies would benefit from slightly early delivery,” Dr. Silver said.
Improved detection and management of FGR may be on the horizon. “Our ability to image the placental function has gotten a lot better, and I think that is really going to help us,” Dr. Silver said. Studies that aim to further improve the ability to assess whether babies are getting adequate blood flow during pregnancy are ongoing, which could further help doctors evaluate risks.
The study investigators and Dr. Silver had no conflict of interest disclosures. Dr. Blue disclosed grants from Samsung Medison and personal fees from Elsevier. The study was supported by a grant from the Australian government’s National Health and Medical Research Council Program, and Mr. Selvaratnam is supported by scholarships from an Australian government research training program and the National Centre of Research Excellence in Stillbirth.
