Rationale: Food allergy has been rising in developing countries especially in cities with modernized life style. Here we reported the prevalence and characteristics of parent-reported food allergies among young children in Bangkok, one of the biggest cities in Thailand.

Methods: A cross-sectional questionnaire survey was conducted in 17 nursery and kindergartens in Bangkok. The questionnaires were answered by parents and validated by telephone interview.   

Results:

Of the 857 participants, 78% were males, age ranged from 1-7 years (mean± SD = 4.55±1.60 years). The prevalence of parent-reported ever having food allergies was 11.3%. Cow’s milk was reported as the most common cause of allergic reaction with 40% of food allergic infants were allergic to cow’s milk. Percentage of other foods causing allergic reaction were: egg 27%, wheat 9%, shellfish 9%, peanut 1.8%, fish 1.8%. The most common reported symptoms were urticaria and eczema. On logistic regression, factors independently associated with parent-reported food allergies were personal history of doctor diagnosed, atopic dermatitis (crude OR 3.65, 95% CI: 1.95-6.84; p < 0.001) and urticaria (crude OR 3.26, 95% CI: 1.29-8.26; p 0.002). Parental history of allergic diseases was not associated with parent report food allergy.

Conclusions:

Prevalence of parent report food allergy in our study was comparable to western countries.  Cow’s milk and egg are the two most common causes of food allergy in this age group.
