Underrecognized impact: how food allergies affect child feeding behavior

Published online September 24, 2024

Food allergies (FA) are a significant chronic health issue affecting approximately 5.6 million children in the United States. Managing FA involves strict dietary restrictions and preparedness for allergic reactions, which can adversely impact growth and psychosocial development. Children with FA often experience unique challenges that contribute to feeding problems, such as food aversions, picky eating, and disruptions in the parent-child feeding relationship. These difficulties can further complicate FA management and affect the overall well-being of both children and their families. Despite these challenges, the connection between FA and feeding issues remains underexplored.

An article by Park et al., published in The Journal of Allergy and Clinical Immunology: In Practice, examined the prevalence and nature of feeding problems in children with IgE-mediated FA and/or pediatric feeding disorder (PFD). The study also explored factors associated with feeding problems in children with FA, providing valuable insights into potential risk factors and underlying mechanisms. Using survey data from 352 parents of children aged 6 months to 7 years, the study compared children with FA (n=50), PFD (n=235), or both (n=67), to healthy peers matched by age, gender, race, and socio-economic status. Parents reported their children's feeding issues using the Pediatric Eating Assessment Tool (PediEAT), a reliable instrument for assessing feeding problems. The matching process ensured fair comparisons between groups, and statistical analyses were conducted to assess feeding problems and identify factors linked to feeding difficulties in children with FA.

The study found that children with FA had significantly higher feeding problems compared to healthy peers. Children with PFD had even more severe feeding difficulties, regardless of the presence of comorbid FA. Factors contributing to increased feeding problems in children with FA included older age, non-White race, increased medical comorbidities, and limited dietary variety. These findings underscore the importance of routine screening and multidisciplinary interventions for children with FA to address feeding and growth concerns. The results emphasize the complex relationship between FA and feeding difficulties, highlighting the need for comprehensive care that considers the many factors influencing feeding behavior in children with FA.
