The reported prevalence of food allergy among school-aged children in Bahrain

Abstract

Allergic diseases have been continuously studied and monitored, while the topic of food allergy (FA) lags with only a few prevalence studies conducted in certain countries. The main aim of this study was to estimate the prevalence of FA in school-aged children in the Kingdom of Bahrain. A cross-sectional design was used on a randomized sample of school-aged children in Bahrain. An electronic questionnaire inquiring about demographic data and history of FA and its details was administered through school administrations between October and December 2020. Data was obtained from 1370 participants, comprising 822 males and 548 females. The prevalence of a reported history of FA in school-aged children in Bahrain was calculated as 15.5%. Furthermore, 9.9% of children reported a current FA. The most common experienced symptoms were skin symptoms followed by gastrointestinal symptoms. Moreover, 7% of children reported experiencing anaphylaxis, low blood pressure, or shock. This research concluded that the reported prevalence of FA history among school-aged children in Bahrain was higher than that observed in other studies estimating at 15.5%, with 9.9% persisting up to the time of the study. The most common single food allergen was found to be egg. The findings of this study provide a baseline for future larger studies to obtain more in-depth results.
