Wide spectrum of feeding problems poses challenge for clinicians

SAN FRANCISCO – Clinicians are likely to encounter diverse feeding problems in daily practice that will challenge their diagnostic and treatment acumen, Dr. Irene Chatoor told attendees of the annual meeting of the American Academy of Pediatrics.

These problems run the gamut from the most prevalent but least serious picky eating, to the least prevalent but most serious feeding disorders, she noted. Correspondingly, management will range from simple reassurance of parents to more intensive behavioral and medical interventions.

Assessment

Regardless of their apparent severity, all feeding problems brought to clinicians’ attention can be a source of anxiety for parents and should be carefully evaluated, recommended Dr. Chatoor, who is a professor of psychiatry and pediatrics at George Washington University, and vice chair of the departments of psychiatry and behavioral sciences at Children’s National Medical Center, both in Washington.

“When you assess a feeding problem, you have to look at both the mother and father, and the child,” she advised. The parents are evaluated for their feeding style, while the child is evaluated for three feeding problems: limited appetite, selective intake, and fear of feeding (Pediatrics. 2015;135[2]:344-53).

Clinicians must be alert for organic red flags, such as dysphagia, aspiration, and vomiting, and for behavioral red flags, such as food fixation, abrupt cessation of feeding after a trigger event, and anticipatory gagging. An overarching red flag is failure to thrive.

Sometimes, a child will have both an organic condition and a behavioral feeding disorder at the same time. “It’s very important that you don’t think one excludes the other,” she cautioned.

Diagnosis

“To delineate milder feeding difficulties from feeding disorders, there must be some form of impairment caused by the feeding problem,” Dr. Chatoor commented. “Why is this important? For two reasons. One is for the insurance companies, because they don’t pay unless there is a disorder. And then there is research: you cannot do research unless you clearly define what you are studying.”

Children are considered to have impairment if they have weight loss or growth faltering, considerable nutritional deficiency, or a marked interference with psychosocial functioning.

“When we diagnose feeding problems, it is best done with a multidisciplinary team,” Dr. Chatoor maintained. “I have learned many years ago that I’m not effective in helping parents deal with the feeding disorder if they are still in the back of their mind worried that the child has something organically wrong and that’s why the child does not want to eat.”

Accordingly, various team members perform a medical examination, a nutritional assessment, an oral motor and sensory evaluation, and a psychiatric or psychological assessment to identify the root cause or causes of the problem.

When it comes to behavioral etiologies, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) now groups all feeding and eating disorders together in one section, reflecting the fact that disorders starting early in life can and often do track into adolescence and adulthood, according to Dr. Chatoor.

The manual also features a new diagnosis, avoidant/restrictive food intake disorder (ARFID). Key criteria include the presence of an eating or feeding disturbance that cannot be better explained by lack of available food, culturally sanctioned practices, or a concurrent medical condition or another mental disorder.

The child must have a persistent failure to meet appropriate nutritional and/or energy needs, associated with any of four findings: significant weight loss or failure to achieve expected weight gain or growth, significant nutritional deficiencies, dependence on enteral feeding or oral nutritional supplements, and marked interference with psychosocial functioning.

“You need to have at least one but often you have a combination of nutritional and emotional impairment in the same child,” she commented.

ARFID and its treatment

There are three subtypes of ARFID having different features, treatments, and prognosis, although they all share in common food refusal, according to Dr. Chatoor.

The first subtype – apparent lack of interest in eating or food – emerges by 3 years of age, most often during the transition to self-feeding between 9 and 18 months. Affected children refuse to eat an adequate amount of food for at least 1 month, rarely communicate hunger, lack interest in food, and prefer to play or talk. They typically present with growth deficiency.

“If you have a child who refuses to eat, it generates anxiety in the mother. The mother does things she would not normally do with the child who is eating well. She starts to distract, to cajole, to sometimes even force-feed the child,” Dr. Chatoor explained. “And the more she engages in these behaviors, the more resistant the child becomes. So they become trapped in this vicious cycle.”

Treatment is aimed at removing this conflict with three approaches: explaining to parents the infant’s special temperament (notably, high arousal and difficulty turning off excitement); addressing their background, including any eating issues of their own, and difficulty with setting limits; and providing specific feeding guidelines and a time-out procedure.

The guidelines stress regular feeding, withholding of all snacks, keeping the child at the table for 20 to 30 minutes, and not using any distractions or pressure. Also, importantly, the parents should have dinner with their child. “I always tell the parents what is good for the child is good for you. It’s good for your whole family,” she said. “If they have other children, these rules apply to everybody. Young children learn to eat by watching their parents eating.”

With early and consistent use of these interventions, about two-thirds of children outgrow this eating/feeding disturbance by mid-childhood, according to Dr. Chatoor.

Children with the second subtype of ARFID – avoidance based on the sensory characteristics of food – consistently refuse to eat certain foods having specific tastes, textures, temperatures, smells, and/or appearances. Onset occurs during the toddler years, when a new or different food is introduced.

“Not only do they refuse the same foods that were aversive, but they also generalize it. So these children are afraid to try other foods and they may end up limiting food groups – they don’t eat any vegetables and some of them don’t eat any meats,” she explained. “They are a challenge because this always causes a nutritional deficiency and they also have problems socially as they get older.”

Treatment varies by age, with gradual desensitization for infants and parent modeling of eating new foods for toddlers. A multifaceted approach is used for preschoolers, combining modeling, giving foods attractive shapes and names, having the child participate in food preparation, and using focused play therapy, such as feeding dolls who are “brave” and try new foods.

Clinicians can explain to affected school-aged children that they are “supertasters,” having more taste buds and therefore experiencing food more intensely, and that they can help their taste buds not react so strongly by starting to eat small amounts of new foods and gradually increasing over time. Parents can let the child make a list of 10 foods they would like to eat, and award them points for “courage” for every bite of a new food they try.

Prognosis of this type of ARFID varies, according to Dr. Chatoor. “Through gradual exposure, young children can expand the variety of foods they eat,” she elaborated. However, “some children become very rigid and brand sensitive in regard to the food they are willing to eat and begin to experience social problems during mid-childhood and adolescence. Some children grow up eating a limited diet, but finding ways to compensate nutritionally and socially.”

Children with the third subtype of ARFID – concern about aversive consequences of eating – have an acute onset of consistent food refusal at any age, from infancy onward, after experiencing a traumatic event or repeated traumatic insults to the oropharynx or gastrointestinal tract that trigger distress in the child. These children often have comorbidities such as gastroesophageal reflux, eosinophilic gastroenteritis, or anxiety disorder.

“Treatment involves gradual desensitization to feared objects: the highchair, bib, bottle, or spoon,” Dr. Chatoor explained. “It also involves training of the mother in behavioral techniques to feed the child in spite of the child’s fear and distress.”

Any underlying medical condition causing pain or distress should be treated. Additional measures may include, for example, use of a graduated approach, starting with liquids and progressing to purees, if the child fears solid foods, and prescribing anxiolytic medication in cases of severe anxiety.

Dr. Chatoor disclosed that she has lectured internationally at conferences on feeding disorders that were organized by Abbott Nutrition International and that the company provided a research grant for a study on feeding.
