A cross‐sectional, population‐based study on the prevalence of food allergies among children in two different socio‐economic regions of Vietnam

Abstract

The prevalence of FA in Vietnamese children seems to be higher than previously reported from other Asian countries. Crustacean is the predominant allergy-inducing food among participating preschool children in Vietnam. The variation of reported food allergen sources across different socio-economic locations could imply different eating habits or the participation of indoor and outdoor allergen exposure.
