Assessing daily food allergy self-management among adolescents using a 24-hour recall interview.

backgroundSevere food allergic reactions can be life-threatening or fatal and are experienced by up to 40% of children with food allergies, with adolescents at greatest risk. There are no comprehensive measures to assess food allergy management behaviors that could prevent allergic reactions.

objectiveTo describe food allergy self-management behaviors as reported by adolescents on a 24-hour recall measure and identify related factors.

methodsAdolescents aged 10 to 14 years with immunoglobulin E-mediated food allergy completed the Food Allergy Management 24-Hour Recall as an interview. Participants answered questions on each food they ate on the previous day and food allergy self-management behaviors.

resultsParticipants were a diverse sample (28% White) of 101 adolescents (mean age = 11.80 years; 53% male sex). Most meals and snacks (76%) were observed by adults. Epinephrine autoinjectors (EAIs) were reportedly available for almost all meals and snacks (93%). Almost all foods had been eaten before (95%) and were verified as allergen free (92%). Furthermore, 35% of the time, past experience with the food was the only method used to verify safety. Child age, number of food allergies, or time since allergic reaction was not related to self-management behavior. EAI availability and ingredient verification were most common at home and in school; adult observation was least likely in the home.

conclusionAdolescents reported that EAIs were frequently available, but they relied on past experience with food to determine safety. Appropriate assessment of food safety should be a primary intervention target. The Food Allergy Management 24-Hour Recall may be a useful tool to assess and track food allergy self-management.
