Prevalence and Impact of Food Allergies Among Jordanian Schoolchildren: A Comprehensive Analysis of Parent-Reported...

Background: Food allergies, characterized by immune reactions to food proteins, have emerged as an increasing global concern, impacting over 10% of the population. This study investigates the prevalence of food allergies among schoolchildren aged 5-14 years in northern and central Jordan. Methods: A randomized cross-sectional online questionnaire was administered to students aged 5-14 years residing in the central and northern regions of Jordan. Parents of these students (n = 1629) completed the questionnaire, which comprised information on demographics, dietary habits, food allergies, and allergy history. Results: The parent-reported food allergies exhibited a prevalence of 11.5% (95% confidence interval = 10-13%). Of these reported allergies, 10.1% (95% CI = 8.6-11.7%) were classified as convincing, while only 5.7% (95% CI = 4.5-6.8%) received a formal diagnosis from a healthcare professional. The most commonly reported allergens included eggs (17.8%), cow's milk (15.8%), peanuts (14.5%), and strawberries (13.8%). The majority of children (67.1%) had a single reported allergen, while 15.8% had two, and 17.2% had more than two allergens identified. Food allergies were significantly more prevalent among children with comorbid atopic conditions and those with a family history of allergies. Additionally, regional variations were observed, with high prevalence rates in metropolitan regions. Conclusion: This study emphasizes the significance of considering persuasive food allergy (FA) data in addition to parent-reported information. The findings highlight the considerable burden of food allergies and their relationship with other atopic disorders. Comprehensive management strategies and further research to elucidate the underlying causes of food allergies are necessary.
