Allergy to food might be linked to anxiety in children: Study

Washington: Are you one of those who have anxiety problems? Your allergy to food items might be one of the reasons for it.

According to a new study, children with a food allergy had a significantly higher prevalence of childhood anxiety.

Food allergies were not associated with symptoms of childhood depression or with symptoms of anxiety or depression among their caregivers.

The team studied 80 pediatric patients aged 4 to12 years, eight years old on average, with and without food allergy and their caregivers from urban pediatric outpatient clinics in the Bronx, New York.

They controlled for an asthma diagnosis in the children, as anxiety and mood disorders are more prevalent among youth with asthma and especially more common in low socioeconomic minority children.

Among the children with a food allergy, 57 percent reported having symptoms of anxiety compared to 48 percent of children without a food allergy. Approximately 48 percent of the children had symptoms of depression with or without a food allergy.

“Management of food allergy can be expensive both in terms of food shopping, meal preparation, and the cost of epinephrine auto-injectors, which expire annually. These demands could result in higher levels of anxiety for those with fewer financial resources and further heighten anxiety symptoms in children and their caregivers,” said Renee Goodwin, PhD, in the Department of Epidemiology at the Mailman School of Public Health and lead author.

The results suggest that food allergy is particularly linked to elevated social anxiety and fear of social rejection and humiliation.

Dr. Goodwin, noted, “There are a number of possible explanations for the relationship found between food allergy diagnosis and increased social anxiety issues in this sample of pediatric patients. Management of a potentially life-threatening condition may be anxiety provoking, and some children may experience increased social anxiety about being “different” from other children depending on their age and how food allergy is managed by adults in a particular setting.”

The researchers also point out a possible explanation for not finding a link between food allergy and depression in children.

The sample was young, and the mean age of onset for depression is significantly later than anxiety.

“It would be worthwhile to examine these relationships among older adolescents and young adults with food allergy who are at the peak of risk for depression onset, especially because early anxiety is associated with increased risk for subsequent onset of depression,” said Jonathan Feldman, PhD, professor of Psychology at Ferkauf Graduate School of Psychology, Yeshiva University.

Dr. Goodwin concluded by saying, “”With the high prevalence of food allergies today, education in schools remains a priority. Given the strong association between food allergy and social anxiety in children future investigations on the food allergy-mental health relationship are also warranted in clinical, school, and community-based settings which could aid in the development of interventions.”
