Methods Thirty-three cities were chosen according to China's geological and demographic distribution.Randomly cluster sampling method was used to choose a community within each city as the sample region,the mothers of children were interviewed and conducted face-to-face questionnaire survey. Results The overall prevalence rate reported from parents for urban 0 to 24 months old was 40.9%(95%CI:40.1%~41.6%),the prevalence rate was 12.3%(95%CI:11.7%~13.0%);among prevalent allergic symptoms,the one with the highest rate was rash and pruritus(62.1%),the second and third highest were symptoms of eyes and nose and gastrointestinal symptoms,accounting for 7.6% and 6.9% respectively;The prevalence rate peaked among infants 4 to 6 months old,prevalence rate dropped sharply among infants older than 6 months(P<0.05).The prevalence rate for boys was higher than that of girls(P<0.05). Conclusions The prevalence rate of allergic diseases in Chinese infants and toddlers is approaching the level of developed countries and regions,signifying the importance of primary prevention for infantile allergic diseases.This study provides data for monitoring the trendy of infantile allergies as well as carrying out allergy screening and prevention.
