Sleep Medicine

Will the weight reduction success with glucagon-like peptide-1 (GLP-1) agonists translate into strong reductions in obstructive sleep apnea (OSA)? Will those potential OSA benefits obviate the need in many for continuous positive airway pressure (CPAP)? Experts are voicing high hopes while citing important health equity concerns and reluctance to de-emphasize lifestyle remedies.

“I think it’s a game changer for helping people who are overweight or obese,” Samuel T. Kuna, MD, chief of sleep medicine at the Corporal Michael J. Crescenz VA Medical Center in Philadelphia, said in an interview with CHEST Physician. “I think we’re just starting out on a very exciting new era. We finally have quite effective treatments for this population.” Dr. Kuna’s Sleep AHEAD (Action for Health in Diabetes) 2021 study (doi: 10.1164/rccm.201912-2511OC) found that participants with OSA and type 2 diabetes mellitus receiving intensive lifestyle interventions for weight loss had reduced OSA severity at 10 years, and that OSA remission at 10 years was more common with intensive lifestyle intervention than with diabetes support and education.

Potential for OSA impact

In a JAMA Network Open/Pulmonary Medicine article on a 2022 study (doi: 10.1001/jamanetworkopen.2022.8212) conducted among 89 Spanish male adults with moderate to severe OSA and body mass index of 25 or greater, participants received CPAP therapy with or without 8 weeks of weight loss and lifestyle intervention. The primary endpoint of apnea-hypopnea index at 6 months showed the intervention to yield “clinically meaningful and sustainable improvements in OSA.”

Dr. Kuna stated, “I don’t think these [weight loss] agents eliminate the importance of behavioral modification, of changing diet, of reducing highly processed foods and maintaining a healthy lifestyle.” He acknowledged, however, that behavioral endeavors have been in general disappointing with respect to patients’ ability to achieve weight loss. “These medicines really open up a new strategy to help patients do that,” he added.

Significant impact on OSA and CPAP

“Obesity is a risk factor for sleep apnea,” stated Saadia A. Faiz, MD, FCCP, professor, Department of Pulmonary Medicine, University of Texas MD Anderson Cancer Center, Houston, “so with increased use of these GLP-1 agents for weight reduction, we would anticipate a significant impact on both OSA severity and need for CPAP.” Speaking in a CHEST Physician interview and referring to the Kuna et al. study, she stated, “Since cessation of the drug can lead to rebound weight gain, the emphasis on healthy eating and exercise is crucial to management.” Dr. Faiz said further, “It’s important to note that there are other weight-independent mechanisms for OSA, including upper airway anatomy, mechanisms that modulate upper airway stability, chemoreceptor sensitivity, visceral adiposity, neuroendocrine control, sleep quality, and other aspects of OSA pathophysiology yet to be discovered.”

Cost an obstacle for some

“For many insurances, criteria for coverage include obesity and prediabetes based on HbA1c. For some not meeting requirements, they will have to pay out of pocket,” Dr. Faiz said. She pointed to a Respirology (doi: 10.1111/resp.14545) commentary in which Garun S. Hamilton, MBBS, PhD, and Bradley A. Edwards, PhD, underscored the nearly 1 billion people worldwide with OSA, most of whom are overweight or obese. “GLP-1 agonists are so effective that they have become a worldwide phenomenon. The high cost of the medications combined with the high prevalence of OSA means that there is no way that universal healthcare funding schemes can afford these medications, unless strict criteria are in place to prioritize those who can gain subsidized access and/or a duration of use limit is in place,” they stated. “This will no doubt exacerbate inequities in healthcare access and outcome between those from lower versus higher socioeconomic populations, as the attributable benefit from GLP-1 agonists is likely to be dependent on a patient’s ability to afford them.”
 

Beyond health equity concerns

The evidence for clinically relevant reductions in weight and resultant lowering of other adverse risk factors supports a wide embrace of Ozempic-type drugs. Standing alongside, however, are the cautionary pleas of nutrition/lifestyle-focused health advocates. They urge that prescriptions for nonpharmacological strategies that promote better sleep, healthier food choices, and more exercise need sharper highlighting and strong incentivizing.

Dr. Faiz said, “The availability and consumption of ultra-processed foods can impact food intake and weight. Specifically, in a small study of 20 inpatient adults admitted to the NIH Clinical Center randomized to either ultra-processed or unprocessed diets for 14 days, increased caloric intake and weight gain were found in the ultra-processed cohort.” In the study Dr. Faiz cited (doi: 10.1016/j.cmet.2019.05.008), meals were matched for calories, energy density, macronutrients, sugar, sodium, and fiber. Subjects were instructed to consume as much or as little as desired. Analysis showed a 4-pound weight difference between groups within 2 weeks: The ultra-processed cohort had taken in an extra 500 calories a day and had gained weight (0.9 ± 0.3 kg [P = .009]) and body fat while the unprocessed food group lost weight (0.9 ± 0.3 kg [P = .007]) and body fat.

“Thus, the type of foods we opt for can also have significant impact,” Dr. Faiz stated.

Dr. Faiz and Dr. Kuna said they had no conflicts of interest to disclose.

Results from a preliminary clinical trial demonstrated the obesity drug, tirzepatide, effectively treated obstructive sleep apnea (OSA), according to information sent to investors of the pharmaceutical company, Eli Lilly.

Indiana-based Eli Lilly sells tirzepatide under the brand name Zepbound, which was approved by the FDA in November to treat overweight and obesity. Tirzepatide is also marketed under the name Mounjaro to treat diabetes, and it’s among the same class of drugs as other well-known weight loss and diabetes drugs like Ozempic and Wegovy.

The newly announced results came from a pair of studies that followed people with moderate to severe OSA who also had obesity. People in the study took tirzepatide, which is given by injection, for one year. One study evaluated people who were using CPAP during sleep, and another study included people who didn’t use the device. People in both studies taking tirzepatide had significant reductions in sleep events and also lost about 20% of body weight. About 70% of people in the studies were men.

The findings have not yet been published in a peer-reviewed medical journal, and the preliminary results were announced by Eli Lilly because of reporting requirements related to information that could affect stock prices. The company indicated that detailed results will be presented at a conference of the American Diabetes Association in June and will be submitted to a peer-reviewed journal for consideration of publication. The company also plans to submit the information to the FDA for approval consideration mid-year, the investor news release stated.

People in the study taking tirzepatide on average experienced 63% fewer instances of reduced oxygen due to breathing changes, or events when breathing entirely stopped, Eli Lilly reported.

A sleep expert from Washington University in St. Louis told The New York Times the initial findings were extremely positive and noted that tirzepatide works to treat the underlying cause of sleep apnea, rather than current treatments that just address symptoms.

Tirzepatide “is a great alternative for people who are obese and can’t use CPAP or are on CPAP and want to improve the effect,” Eric Landsness, MD, PhD, told The New York Times. 

Eli Lilly indicated the most commonly reported adverse events in the studies were diarrhea, nausea, vomiting, and constipation.

An estimated 39 million people have OSA and about 33 million people use CPAP machines, according to The National Council on Aging. The condition has been increasingly diagnosed in recent years and becomes more likely to affect people as they get older.

TOPLINE:

Less than 7 hours of sleep per night is common in individuals with type 1 diabetes (T1D) but is tied to poor cardiometabolic health, particularly in adolescents.

METHODOLOGY:

• Sleep is recognized as an important factor in diabetes assessment and treatment by the 2023 American Diabetes Association’s Standards of Medical Care in Diabetes, but it is unclear whether sleep may improve health outcomes across the lifespan in patients with T1D.
• This secondary analysis of the BCQR-T1D crossover trial investigated the link between sleep and cardiometabolic health in 42 adults (age, 19-60 years) and 42 adolescents (age, 12-18 years) with T1D.
• Participants had T1D duration greater than 9 months and received bromocriptine quick-release (BCQR) therapy or placebo for 4 weeks and then switched between the treatments in a separate 4-week period.
• They underwent laboratory testing and anthropometric measurements. Also, continuous glucose monitoring data were collected for a week during each treatment phase along with an accompanying insulin dosing diary.
• Participants were required to wear an actigraphy monitor on the wrist of their nondominant hand for 7 days during each treatment phase to estimate sleep duration.

TAKEAWAY:

• Most adolescents (62%) and adults (74%) with T1D reported less than 7 hours of sleep at baseline.
• Participants with insufficient sleep versus those without insufficient sleep (< 7 vs > 7 hours) had a larger waist circumference and higher mean body mass index, systolic blood pressure, and pulse pressure, as well as lower estimated insulin sensitivity and brachial artery distensibility (P < .05 for all).
• When stratified by age, only adolescents with T1D with insufficient sleep had significant differences in most health outcomes by sleep duration status, except that adults with less than 7 hours of sleep had higher pulse pressure than those with more than 7 hours of sleep.
• Compared with placebo, BCQR slightly improved sleeping parameters in adolescents by delaying their time of waking up and prolonging their time in bed.

IN PRACTICE:

“Sleep may be an important and novel target for improving health in individuals with T1D, particularly when initiated in adolescence or early in diabetes,” the authors wrote.

SOURCE:

Stacey L. Simon, PhD, and Janet K. Snell-Bergeon, PhD, University of Colorado Anschutz Medical Campus, Aurora, led this study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study lacked polysomnography or melatonin assessment to quantify circadian rhythms and subjective sleep quality ratings. It also had no objective measurement of the timing of the daily pills of BCQR, which, when taken in the morning, are hypothesized to reset the circadian rhythm for hypothalamic dopamine and serotonin. The recommended sleep duration of 8 hours for adolescents was not used as the cutoff value due to too few participants who qualified. Also, this study›s findings may be affected by the fact that participants were recruited throughout the year, while adolescents show different sleeping patterns during the academic year compared with school breaks.

DISCLOSURES:

This work was supported by a JDRF grant. Two authors declared receiving equipment, honoraria for lectures, and support for conference travel, which were all unrelated to this study.

Use of a mandibular advancement device (MAD) proved non-inferior to guideline-recommended continuous positive airway pressure (CPAP) to reduce blood pressure in patients with hypertension and obstructive sleep apnea (OSA), in a randomized trial.

The investigator-initiated CRESCENT trial showed that at 6 months, the MAD group had a reduction of 2.5 mm Hg in 24-hour mean arterial blood pressure vs no change in the CPAP group, for a nonsignificant between-group difference of 1.6 mm Hg. 

“These findings suggest that MAD could be considered an alternative to CPAP for optimizing blood pressure control in OSA patients with hypertension and high cardiovascular risk,” the researchers conclude. 

“Looking at the totality of evidence available in the literature, it is still reasonable to say that CPAP is the first-line treatment until we have more data on the MAD,” said Ronald Lee Chi-Hang, MD, professor of medicine at Yong Loo Lin School of Medicine, National University of Singapore, who presented the results.

“However, for patients who truly cannot tolerate or accept using a CPAP, we should be more open-minded in looking for an alternative therapy such as a MAD, which based on our study, numerically had a better blood pressure reduction in patients compared with a CPAP,” said Dr. Chi-Hang, who is also a senior consultant in the Department of Cardiology at Singapore’s National University Heart Centre. 

The results were presented April 6 at the American College of Cardiology Scientific Sessions 2024 and published online simultaneously in the Journal of the American College of Cardiology

OSA is increasingly recognized as “an underdiagnosed and modifiable cause of hypertension,” the researchers note in their report. “Patients with OSA develop recurrent collapse of the upper airway during sleep, resulting in hypoxemia, sympathetic hyperactivity, and BP surges.” 

Current guidelines recommend screening and treatment of OSA in patients with hypertension, and CPAP is considered first-line therapy, they note. 

“Despite being effective, unfortunately, many patients decline to use a CPAP or find it challenging to stick to the therapy,” Dr. Chi-Hang said, particularly those without daytime sleepiness. 

MADs are oral appliances that work by advancing the mandible about 5 to 10 mm during sleep, he said. They provide an alternative to OSA patients and have been shown to improve daytime sleepiness and quality of life, “and in general, is better accepted and tolerated than CPAP.” 

However, early studies are small, with short follow up, included patients with and without hypertension, and didn’t specify BP reduction as the primary outcome. 

The CRESCENT trial was an investigator-initiated, randomized, non-inferiority trial that aimed to compare the relative effectiveness of MAD vs CPAP in reducing 24-hour ambulatory blood pressure in patients with moderate-to-severe OSA, hypertension and high cardiovascular risk. The prespecified margin for non-inferiority was 1.5 mm Hg. 

A total of 321 participants were recruited at three public hospitals for polysomnography. All were older than age 40 years, had hypertension, and were at increased cardiovascular risk. Of these, 220 with moderate-to-severe OSA, defined as an apnea–hypopnea index (AHI) of ≥ 15 events/hour, were randomly assigned to either MAD or CPAP treatment. 

The primary outcome was the difference between the 24-hour mean arterial BP at baseline and 6 months. The median age was 61 years, most patients (85.5%) were male, and all were Chinese. All had essential hypertension and were on one or more antihypertensive medications. Hypertension was relatively well controlled at baseline.

At 6 months, 24-hour mean arterial BP decreased by 2.5 mm Hg in the MAD group (P = .003) compared to no change from baseline in the CPAP group (P = .374). 

The between-group difference was -1.6 mm Hg (95% CI, -3.51 to 0.24, non-inferiority P < .001). 

There was a larger between-group reduction in all secondary ambulatory BP parameters in the MAD versus the CPAP group, with the most pronounced effects seen in the asleep BP parameters. 

Both the MAD and CPAP significantly improved daytime sleepiness, with no between-group differences (P =.384). There were no between-group differences in cardiovascular biomarkers. 

During the presentation, panel discussant Julie B. Damp, MD, associate professor of medicine at Vanderbilt Health in Nashville, Tennessee, called CRESCENT “a really interesting study, and I think it has a lot of information to add [regarding] what we know about this comparison in the literature, because this is a big study and it also followed these patients for longer than we’ve seen in some of the previous studies.”

Dr. Damp asked, however, about how these results might be extrapolated to other populations, since the vast majority of participants were male. 

Dr. Chi-Hang pointed out that most OSA studies include mostly male patients, but noted that particularly in Asian culture, female patients may be more conservative in seeking treatment for problems with snoring, poor quality of sleep, or extensive daytime sleepiness. “Therefore, lots of times, even in clinical practice, we see that over 80 or 90% of patients are male patients,” he said. 

Dr. Damp followed up by asking about the differential effectiveness of CPAP vs MAD. “Just in thinking about these two therapies, there is some evidence that the mandibular devices are potentially less effective on some of the sleep apnea-specific measures, so how much of this do you think is an issue of a better vs a not better treatment as opposed to an issue truly of compliance and what patients are able to tolerate?”

Dr. Chi-Hang agreed that in terms of reducing the AHI, CPAP is more effective than MAD. “In fact, in our data, the residual AHI was 10 for the MAD group and 2 for the CPAP group. Clearly, CPAP is more effective,” he said. “But the problem we are facing in this area is the value of AHI as an index is being questioned.” 

AHI considers only the number of events, without taking into account the duration or the depth of the apnea, he said. “AHI is simply not an ideal index to document the disease severity,” or the impact on cardiovascular outcomes. 
 

A Tailored Approach

In an editorial accompanying the JACC publication, Michele Emdin, MD, PhD, Francesco Gentile, MD, and Alberto Giannoni, MD, PhD, all from the Health Science Interdisciplinary Center, Scuola Superiore Sant’ Anna, and Fondazione Toscana Gabriele Monasterio, in Pisa, Italy, commend the researchers for designing and conducting “such a pragmatic and informative trial, which confirms and extends previous findings.” 

They also discuss the compliance vs effectiveness issue, pointing out that although CPAP appeared to be more effective in reducing apnea burden, there was higher adherence to MAD — with 57% using the device 6 or more hours per night, vs 23% for CPAP — which might have offset the greater reduction in apnea burden and resulted in the reduction in blood pressure seen in the trial. 

“Addressing poor adherence to OSA treatments seems therefore necessary, particularly in the case of less symptomatic patients, who often have a lower perception of the related risks,” they write. 

“Currently, a tailored approach seems reasonable, based on updated evidence, considering: a) the differential effects of CPAP or MAD on OSA, blood pressure; b) the treatment feasibility; c) the individual baseline demographic and clinical characteristics, including the presence of resistant hypertension; and d) compliance with the therapeutic tool and patient’s preferences,” the editorialists conclude. 

The study was funded by the Singapore Ministry of Health. The authors and editorialists report no relevant financial relationships.

Use of a mandibular advancement device (MAD) proved non-inferior to guideline-recommended continuous positive airway pressure (CPAP) to reduce blood pressure in patients with hypertension and obstructive sleep apnea (OSA), in a randomized trial.

The investigator-initiated CRESCENT trial showed that at 6 months, the MAD group had a reduction of 2.5 mm Hg in 24-hour mean arterial blood pressure vs no change in the CPAP group, for a nonsignificant between-group difference of 1.6 mm Hg. 

“These findings suggest that MAD could be considered an alternative to CPAP for optimizing blood pressure control in OSA patients with hypertension and high cardiovascular risk,” the researchers conclude.

TOPLINE:

Over time, exercising at least twice a week is associated with significantly fewer insomnia symptoms and better sleep duration, new research shows.

METHODOLOGY:

• The study included 4339 adults aged 39-67 years (48% men) from 21 centers in nine countries participating in the third follow-up to the European Community Respiratory Health Survey (ECRHS III).
• Participants responded to questions about physical activity, insomnia symptoms, sleep duration, and daytime sleepiness at 10-year follow-up.
• Being “physically active” was defined as exercising with a frequency of at least twice a week for ≥ 1 hour per week.
• The main outcome measures were insomnia, sleep time, and daytime sleepiness in relation to physical activity.

TAKEAWAY:

• From baseline to follow-up, 37% of participants were persistently inactive, 25% were persistently active, 20% became inactive, and 18% became active.
• After adjustment for age, sex, body mass index, smoking history, and study center, persistently active participants were less likely to report difficulties with sleep initiation (adjusted odds ratio [aOR], 0.60; 95% CI, 0.45-0.78), with short sleep duration of ≤ 6 hours/night (aOR, 0.71; 95% CI, 0.59-0.85) and long sleep of ≥ 9 hours/night (aOR, 0.53; 95% CI, 0.33-0.84), compared with persistently nonactive subjects.
• Those who were persistently active were 22% less likely to report any symptoms of insomnia, 40% less likely to report two symptoms, and 37% less likely to report three symptoms.
• Daytime sleepiness and difficulties maintaining sleep were found to be unrelated to physical activity status.

IN PRACTICE:

“This study has a long follow-up period (10 years) and indicates strongly that consistency in physical activity might be an important factor in optimizing sleep duration and reducing the symptoms of insomnia,” the authors wrote.

SOURCE:

Erla Björnsdóttir, of the Department of Psychology, Reykjavik University, Reykjavik, Iceland, was the co-senior author and corresponding author of the study. It was published online on March 25 in BMJ Open.

LIMITATIONS:

It’s unclear whether individuals who were active at both timepoints had been continuously physically active throughout the study period or only at those two timepoints. Sleep variables were available only at follow-up and were all subjectively reported, meaning the associations between physical activity and sleep may not be longitudinal. Residual confounders (eg, mental health and musculoskeletal disorders or chronic pain) that can influence both sleep and exercise were not explored.

DISCLOSURES:

Financial support for ECRHS III was provided by the National Health and Medical Research Council (Australia); Antwerp South, Antwerp City: Research Foundation Flanders (Belgium); Estonian Ministry of Education (Estonia); and other international agencies. Additional sources of funding were listed on the original paper. The authors reported no relevant financial relationships.

As your patient’s scheduled bedtime is approaching, they begin to worry another restless night is looming. Could magnesium oil spray actually help them sleep? Some — even doctors — are sharing testimonials about how this simple tactic transformed their sleep quality. Experts suggest some sleep improvement is possible, though it does not negate the need for treatment, and should not be used in patients with cardiovascular disease.

Take Daniel Barrett, MD, a board-certified plastic surgeon and owner of Barrett Plastic Surgery in Beverly Hills, as an example. He decided to test whether magnesium oil could indeed give him a sleepy sensation and shared his experience. Dr. Barrett sprayed magnesium oil on his feet — until they felt “slippery and wet,” he said — and put his socks back on. (He said magnesium is absorbed more easily through the skin. Putting it on the skin helps this mineral get into the lymphatics and circulatory system, offering a way to get a higher concentration of magnesium in the bloodstream. The pores on the feet are also said to be the largest on the body, making them an ideal place for absorption.) 

“My central nervous system had calmed down a bit — it’s similar to what I feel when I take oral magnesium as well. It took about 15 minutes to feel the effect,” Dr. Barrett said.

Research shows that magnesium blocks N-methyl-D-aspartate (a receptor that can hinder sleep) and stimulates gamma-aminobutyric acid (a receptor that can promote good sleep), said Dennis Auckley, MD, director of MetroHealth’s Center for Sleep Medicine. And studies looking at the effects of oral magnesium have shown that taking it may be linked to better self-reported sleep quality and less daytime sleepiness, he said. But traditional magnesium supplements taken orally can sometimes come with side effects in your gut, so putting magnesium on the skin could help to avoid this. 

Magnesium oil on the feet could also help with certain sleep disturbances, such as nocturnal leg cramps and restless legs syndrome, said Sam Kashani, MD, a sleep medicine specialist and assistant clinical professor at UCLA Medical School. (Nocturnal leg cramps – one of the most common secondary factors of insomnia and sleep disturbances in older adults – includes sudden, painful contractions in the lower leg muscles while sleeping. Restless legs syndrome, on the other hand, is like nocturnal leg cramps, but minus the painful contractions, said Dr. Kashani.) 

“Magnesium is a mineral that does have some benefit with regard to reducing the muscle tightness and promoting a little bit more of relaxation of the muscles,” Dr. Kashani said. “This [magnesium oil on your soles] could be beneficial for these types of sleep problems.” 

Still, sleep medicine experts stressed that putting magnesium oil on your feet should not be viewed a cure-all for sleep troubles. 

“High-quality scientific evidence supporting magnesium as a sleep remedy is severely limited,” said Emerson Wickwire, PhD, an American Academy of Sleep Medicine spokesperson and section head of sleep medicine at the University of Maryland Medical School. “Certainly, magnesium is not supported as a treatment for sleep disorders.” 

If your patients plan to use magnesium oil on their feet to help them sleep, make sure they carefully follow the directions to make sure they are taking the proper dosage. Most importantly, patients with a history of cardiovascular complications, or issues with the heart and blood vessels should consult their doctor. 

“Magnesium is an electrolyte that has multiple roles and functions in the body, including within our cardiovascular system,” Dr. Kashani said. “So, if you are somebody who has heart troubles, you definitely want to talk to your primary doctor about any kind of supplements that you are taking, including magnesium.”

As your patient’s scheduled bedtime is approaching, they begin to worry another restless night is looming. Could magnesium oil spray actually help them sleep? Some — even doctors — are sharing testimonials about how this simple tactic transformed their sleep quality. Experts suggest some sleep improvement is possible, though it does not negate the need for treatment, and should not be used in patients with cardiovascular disease.

Take Daniel Barrett, MD, a board-certified plastic surgeon and owner of Barrett Plastic Surgery in Beverly Hills, as an example. He decided to test whether magnesium oil could indeed give him a sleepy sensation and shared his experience. Dr. Barrett sprayed magnesium oil on his feet — until they felt “slippery and wet,” he said — and put his socks back on. (He said magnesium is absorbed more easily through the skin. Putting it on the skin helps this mineral get into the lymphatics and circulatory system, offering a way to get a higher concentration of magnesium in the bloodstream. The pores on the feet are also said to be the largest on the body, making them an ideal place for absorption.) 

“My central nervous system had calmed down a bit — it’s similar to what I feel when I take oral magnesium as well. It took about 15 minutes to feel the effect,” Dr. Barrett said.

Research shows that magnesium blocks N-methyl-D-aspartate (a receptor that can hinder sleep) and stimulates gamma-aminobutyric acid (a receptor that can promote good sleep), said Dennis Auckley, MD, director of MetroHealth’s Center for Sleep Medicine. And studies looking at the effects of oral magnesium have shown that taking it may be linked to better self-reported sleep quality and less daytime sleepiness, he said. But traditional magnesium supplements taken orally can sometimes come with side effects in your gut, so putting magnesium on the skin could help to avoid this. 

Magnesium oil on the feet could also help with certain sleep disturbances, such as nocturnal leg cramps and restless legs syndrome, said Sam Kashani, MD, a sleep medicine specialist and assistant clinical professor at UCLA Medical School. (Nocturnal leg cramps – one of the most common secondary factors of insomnia and sleep disturbances in older adults – includes sudden, painful contractions in the lower leg muscles while sleeping. Restless legs syndrome, on the other hand, is like nocturnal leg cramps, but minus the painful contractions, said Dr. Kashani.) 

“Magnesium is a mineral that does have some benefit with regard to reducing the muscle tightness and promoting a little bit more of relaxation of the muscles,” Dr. Kashani said. “This [magnesium oil on your soles] could be beneficial for these types of sleep problems.” 

Still, sleep medicine experts stressed that putting magnesium oil on your feet should not be viewed a cure-all for sleep troubles. 

“High-quality scientific evidence supporting magnesium as a sleep remedy is severely limited,” said Emerson Wickwire, PhD, an American Academy of Sleep Medicine spokesperson and section head of sleep medicine at the University of Maryland Medical School. “Certainly, magnesium is not supported as a treatment for sleep disorders.” 

If your patients plan to use magnesium oil on their feet to help them sleep, make sure they carefully follow the directions to make sure they are taking the proper dosage. Most importantly, patients with a history of cardiovascular complications, or issues with the heart and blood vessels should consult their doctor.

TOPLINE:

Long naps of an hour or more, naps in the morning, or regular siestas may increase blood glucose levels in older people with type 2 diabetes (T2D).

METHODOLOGY:

• Napping is common in China and other cultures and may play a role in cardiometabolic health, but previous studies on the relationship between napping and glycemic control in T2D have reported conflicting results.
• In a cross-sectional study, the researchers assessed 226 individuals with T2D (median age, 67 years; about half women; mostly retired) from two community healthcare centers in China between May 2023 and July 2023.
• Using questionnaires, the participants were evaluated for A1c levels, as well as frequency, duration (shorter or longer than 1 hour), timing, and type of napping behavior (restorative for lack of sleep vs appetitive by habit or for enjoyment).
• Multivariate analysis controlled for age, sex, body mass index, T2D treatment regimen, diabetes duration, cognitive impairment, depression, night sleep duration, and insomnia symptoms.

TAKEAWAY:

• Among 180 participants who reported napping, 61 (33.9%) took long naps of 60 minutes and more, 162 (90%) reported afternoon napping, and 131 (72.8%) displayed appetitive napping.
• Restorative napping was linked to lower A1c levels than appetitive napping (β, −0.176; P = 0.028).
• Napping frequency was not associated with A1c levels.

IN PRACTICE:

“In clinical practice, healthcare professionals may offer tips about napping, eg, taking a nap less than an hour, taking a nap in the afternoon instead of in the morning, avoiding appetitive napping,” the authors concluded.

SOURCE:

The study, from corresponding author Bingqian Zhu, PhD, of the Shanghai Jiao Tong University School of Nursing, Shanghai, was published in Frontiers in Endocrinology.

LIMITATIONS:

The participants were older individuals, mostly retired, who may have had less need for restorative napping and more time for appetitive napping, limiting generalizability. The sample size may have been too small to find a link to napping frequency. Self-reported data could introduce recall bias. Only A1c levels were used as a measure of glycemic control.

DISCLOSURES:

The study was supported by the National Natural Science Foundation of China and other sources. The authors declared no potential conflict of interest.

Symptoms of sleep apnea, including snorting, gasping, or paused breathing during sleep, are associated with a significantly greater risk for problems with cognitive and memory problems, results from a large study showed.

Data from a representative sample of US adults show that those who reported sleep apnea symptoms were about 50% more likely to also report cognitive issues versus their counterparts without such symptoms.

“For clinicians, these findings suggest a potential benefit of considering sleep apnea as a possible contributing or exacerbating factor in individuals experiencing memory or cognitive problems. This could prompt further evaluation for sleep apnea, particularly in at-risk individuals,” said study investigator Dominique Low, MD, MPH, Department of Neurology, Boston Medical Center.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

Need to Raise Awareness

The findings are based on 4257 adults who participated in the 2017-2018 National Health and Nutrition Examination Survey and completed questionnaires covering sleep, memory, cognition, and decision-making abilities.

Those who reported snorting, gasping, or breathing pauses during sleep were categorized as experiencing sleep apnea symptoms. Those who reported memory trouble, periods of confusion, difficulty concentrating, or decision-making problems were classified as having memory or cognitive symptoms.

Overall, 1079 participants reported symptoms of sleep apnea. Compared with people without sleep apnea, those with symptoms were more likely to have cognitive problems (33% vs 20%) and have greater odds of having memory or cognitive symptoms, even after adjusting for age, gender, race, and education (adjusted odds ratio, 2.02; P < .001).

“While the study did not establish a cause-and-effect relationship, the findings suggest the importance of raising awareness about the potential link between sleep and cognitive function. Early identification and treatment may improve overall health and potentially lead to a better quality of life,” Dr. Low said.

Limitations of the study include self-reported data on sleep apnea symptoms and cognitive issues sourced from one survey.
 

Consistent Data

Reached for comment, Matthew Pase, PhD, with the Turner Institute for Brain and Mental Health, Monash University, Melbourne, Australia, said the results are similar to earlier work that found a link between obstructive sleep apnea and cognition.

For example, in a recent study, the presence of mild to severe OSA, identified using overnight polysomnography in five community-based cohorts with more than 5900 adults, was associated with poorer cognitive test performance, Dr. Pase said.

“These and other results underscore the importance of healthy sleep for optimal brain health. Future research is needed to test if treating OSA and other sleep disorders can reduce the risk of cognitive impairment,” Dr. Pase said.

Yet, in its latest statement on the topic, the US Preventive Services Task Force concluded there remains insufficient evidence to weigh the balance of benefits and harms of screening for OSA among asymptomatic adults and those with unrecognized symptoms.

The study had no specific funding. Dr. Low and Dr. Pase had no relevant disclosures.

For Courtney Stinson, ensuring her daughter’s comfort is a constant battle against the challenges of congenital myopathy. At 9 years old, she relies on a ventilator to breathe, has multiple respiratory treatments daily, and is under the constant care of rotating skilled caregivers. Last year alone, she endured 36 doctor appointments.

To ease her daughter’s struggles with sleep, and after consulting a pediatrician, Ms. Stinson turned to melatonin, a hormone naturally produced by the body to manage sleep. She gave her daughter a low dose of melatonin and saw significant improvement in her ability to settle down, especially when her mind raced.

“She would have such a hard time sleeping when everything is swirling in her head,” said Ms. Stinson, a mother of two who lives in Milan, Michigan. “It’s really been helpful when her brain is moving 100 miles an hour.”

Melatonin is sold without a prescription as a sleep aid in the form of a supplement. For some parents, especially those whose children have complex needs, melatonin can be a valuable resource — but the rise in melatonin across otherwise healthy populations has had its consequences, too, according to pediatric sleep experts. 

Recent data from the CDC illustrates one of these drawbacks: a significant surge in accidental melatonin ingestion among young children over the past 2 decades.

Between 2012 and 2021, poison center calls related to pediatric melatonin exposures skyrocketed by 530%, while emergency department visits for unsupervised melatonin ingestion by infants and young children surged by 420% from 2009 to 2020, according to the CDC report.

Between 2019 and 2022, an estimated 10,930 emergency room visits were linked to 295 cases of children under the age of 6 ingesting melatonin. These incidents accounted for 7.1% of all emergency department visits for medication exposures in this age group, according to the report.

The share of U.S. adults using melatonin increased from 0.4% during 1999 to 2000 to 2.1% during 2017 to 2018.

Doctors say the escalating number of melatonin-related incidents underscores the need for increased awareness and safety measures to protect young children from unintentional overdose, which can cause nausea, vomiting, diarrhea, dizziness, and confusion.

“I do think there is a safe way to use it in certain children, but it should only be used under the guidance of a physician,” said Laura Sterni, MD, director of the Johns Hopkins Pediatric Sleep Center. “There are dangers to using it without that guidance.”
 

Almost 1 in 5 Children Use Melatonin 

Nearly 1 in 5 school-age children and preteens take melatonin for sleep, according to research published last year in JAMA Pediatrics, which also found that 18% of children between 5 and 9 take the supplement.

The American Academy of Sleep Medicine issued a warning in 2022 advising parents to approach the sleep aid with caution. 

“While melatonin can be useful in treating certain sleep-wake disorders, like jet lag, there is much less evidence it can help healthy children or adults fall asleep faster,” M. Adeel Rishi, MD, vice chair of the Academy of Sleep Medicine’s Public Safety Committee, warned on the academy’s site. “Instead of turning to melatonin, parents should work on encouraging their children to develop good sleep habits, like setting a regular bedtime and wake time, having a bedtime routine, and limiting screen time as bedtime approaches.”
 

What’s the Best Way to Give Kids Melatonin?

Melatonin has been found to work well for children with attention deficit hyperactive disorder (ADHD), autism spectrum disorder, or other conditions like blindness that can hinder the development of a normal circadian rhythm. 

But beyond consulting a pediatrician, caregivers whose children are otherwise healthy should consider trying other approaches to sleep disruption first, Dr. Sterni said, and things like proper sleep hygiene and anxiety should be addressed first. 

“Most sleep problems in children really should be managed with behavioral therapy alone,” she said. “To first pull out a medication to treat that I think is the wrong approach.”

Sterni also recommends starting with the lowest dose possible, which is 0.5 milligrams, with the help of pediatrician. It should be taken 1 to 2 hours before bedtime and 2 hours after their last meal, she said. 

But she notes that because melatonin is sold as a supplement and is not regulated by the FDA, it is impossible to know the exact amount in each dose.

According to JAMA, out of 25 supplements of melatonin, most of the products contained up to 50% more melatonin than what was listed.
 

Dangers of Keeping It Within Reach 

One of the biggest dangers for children is that melatonin is often sold in the form of gummies or chewable tablets — things that appeal to children, said Jenna Wheeler, MD, a pediatric critical care doctor at Orlando Health Arnold Palmer Hospital for Children. 

Because it is sold as a supplement, there are no child-safe packaging requirements. 

“From a critical care standpoint, just remember to keep it up high, not on the nightstand or in a drawer,” Dr. Wheeler said. “A child may eat the whole bottle, thinking, ‘This is just like fruits snacks.’ ”

She noted that the amount people need is often lower than what they buy at the store, and that regardless of whether it is used in proper amounts, it is not meant to be a long-term supplement — for adults or for children.

“Like with anything that’s out there, it’s all about how it’s used,” Dr. Wheeler said. “The problem is when kids get into it accidentally or when it’s not used appropriately.”

“Like with anything that’s out there, it’s all about how it’s used,” Dr. Wheeler said. “The problem is when kids get into it accidentally or when it’s not used appropriately.”

For Courtney Stinson, ensuring her daughter’s comfort is a constant battle against the challenges of congenital myopathy. At 9 years old, she relies on a ventilator to breathe, has multiple respiratory treatments daily, and is under the constant care of rotating skilled caregivers. Last year alone, she endured 36 doctor appointments.

To ease her daughter’s struggles with sleep, and after consulting a pediatrician, Ms. Stinson turned to melatonin, a hormone naturally produced by the body to manage sleep. She gave her daughter a low dose of melatonin and saw significant improvement in her ability to settle down, especially when her mind raced.

“She would have such a hard time sleeping when everything is swirling in her head,” said Ms. Stinson, a mother of two who lives in Milan, Michigan. “It’s really been helpful when her brain is moving 100 miles an hour.”

Melatonin is sold without a prescription as a sleep aid in the form of a supplement. For some parents, especially those whose children have complex needs, melatonin can be a valuable resource — but the rise in melatonin across otherwise healthy populations has had its consequences, too, according to pediatric sleep experts. 

Recent data from the CDC illustrates one of these drawbacks: a significant surge in accidental melatonin ingestion among young children over the past 2 decades.

Between 2012 and 2021, poison center calls related to pediatric melatonin exposures skyrocketed by 530%, while emergency department visits for unsupervised melatonin ingestion by infants and young children surged by 420% from 2009 to 2020, according to the CDC report.

Between 2019 and 2022, an estimated 10,930 emergency room visits were linked to 295 cases of children under the age of 6 ingesting melatonin. These incidents accounted for 7.1% of all emergency department visits for medication exposures in this age group, according to the report.

The share of U.S. adults using melatonin increased from 0.4% during 1999 to 2000 to 2.1% during 2017 to 2018.

Doctors say the escalating number of melatonin-related incidents underscores the need for increased awareness and safety measures to protect young children from unintentional overdose, which can cause nausea, vomiting, diarrhea, dizziness, and confusion.

“I do think there is a safe way to use it in certain children, but it should only be used under the guidance of a physician,” said Laura Sterni, MD, director of the Johns Hopkins Pediatric Sleep Center. “There are dangers to using it without that guidance.”
 

Almost 1 in 5 Children Use Melatonin 

Nearly 1 in 5 school-age children and preteens take melatonin for sleep, according to research published last year in JAMA Pediatrics, which also found that 18% of children between 5 and 9 take the supplement.

The American Academy of Sleep Medicine issued a warning in 2022 advising parents to approach the sleep aid with caution. 

“While melatonin can be useful in treating certain sleep-wake disorders, like jet lag, there is much less evidence it can help healthy children or adults fall asleep faster,” M. Adeel Rishi, MD, vice chair of the Academy of Sleep Medicine’s Public Safety Committee, warned on the academy’s site. “Instead of turning to melatonin, parents should work on encouraging their children to develop good sleep habits, like setting a regular bedtime and wake time, having a bedtime routine, and limiting screen time as bedtime approaches.”
 

What’s the Best Way to Give Kids Melatonin?

Melatonin has been found to work well for children with attention deficit hyperactive disorder (ADHD), autism spectrum disorder, or other conditions like blindness that can hinder the development of a normal circadian rhythm. 

But beyond consulting a pediatrician, caregivers whose children are otherwise healthy should consider trying other approaches to sleep disruption first, Dr. Sterni said, and things like proper sleep hygiene and anxiety should be addressed first. 

“Most sleep problems in children really should be managed with behavioral therapy alone,” she said. “To first pull out a medication to treat that I think is the wrong approach.”

Sterni also recommends starting with the lowest dose possible, which is 0.5 milligrams, with the help of pediatrician. It should be taken 1 to 2 hours before bedtime and 2 hours after their last meal, she said. 

But she notes that because melatonin is sold as a supplement and is not regulated by the FDA, it is impossible to know the exact amount in each dose.

According to JAMA, out of 25 supplements of melatonin, most of the products contained up to 50% more melatonin than what was listed.
 

Dangers of Keeping It Within Reach 

One of the biggest dangers for children is that melatonin is often sold in the form of gummies or chewable tablets — things that appeal to children, said Jenna Wheeler, MD, a pediatric critical care doctor at Orlando Health Arnold Palmer Hospital for Children. 

Because it is sold as a supplement, there are no child-safe packaging requirements. 

“From a critical care standpoint, just remember to keep it up high, not on the nightstand or in a drawer,” Dr. Wheeler said. “A child may eat the whole bottle, thinking, ‘This is just like fruits snacks.’ ”

She noted that the amount people need is often lower than what they buy at the store, and that regardless of whether it is used in proper amounts, it is not meant to be a long-term supplement — for adults or for children.
