Abstract

Food allergy affects 8% of preschool children, but factors responsible for food allergy in children are poorly understood. Use of antacid medication may be a contributing factor. The purpose of this study was to determine if parent-reported antacid medication use was associated with higher prevalence of food allergy in atopic children. In this cross-sectional study, parents of children with atopic diseases completed a questionnaire relating to a history of treatment with antacid medication and food allergy. Charts were independently reviewed for food-specific IgE and/or skin-prick test results. Food allergy was defined as a reaction to a food consistent with the anaphylaxis consensus statement and either an elevated food-specific IgE or a positive food skin-prick test. One hundred four questionnaires were completed. Mean age of the participating children was 7.0 ± 4.3 years (range, 5 months to 18 years of age). Forty-seven (45%) individuals were reported to have taken an antacid medication in the past. History of taking antacid medication was associated with an increased prevalence (57% (27)/47 versus 32% (18)/57) and higher prevalence of food allergy of having food allergy (aPR, 1.7 [1.1-2.5]). Mean peanut food-specific IgE was higher in those with a history of taking antacid medication (11.0 ± 5.0 versus 2.0 ± 5.5.; p = 0.01). History of treatment with antacid medication is associated with an increased prevalence of having food allergy.
