Prevalence and distribution patterns of allergens among children with asthma and asthma-like symptoms in Shanghai, China.

ABSTRACT: OBJECTIVE:We aimed to identify the prevalence and distribution patterns of allergens among Chinese children with asthma/asthma-like symptoms (ALS). METHODS:A total of 3479 children with asthma/ALS were enrolled. Skin prick test (SPT) was used to test the allergen-specific IgE. We analysed allergens prevalence and distribution, and its relationship with demographic characteristics. RESULTS:Aeroallergens prevalence was higher than that of food allergens (p < 10- 4). Boys had higher aeroallergens prevalence than that in girls (p < 10- 4). Significant difference of aeroallergens prevalence among cases with different parental allergy history was observed (p < 10- 4). Age was positively associated with aeroallergens prevalence before the age of 11.5 (P < 10- 4), particularly before the age of 2.
