Abstract: Objective To investigate the prevalence of urticaria among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 5 main districts of Nanjing City.Results The number of valid questionnaires was 13 610,accounting for 92.8％ of total respondents.Among the 13 610 respondents,1 116 were diagnosed as urticaria,including 565 boys and 551 girls,with the total prevalence rate being 8.54％.No significant difference was observed in the prevalence rate of urticaria between boys and girls (8.49％ vs.8.60％,x2 =0.04,P =0.832) or among children of different age groups (x2 =1.84,P =0.17).The prevalence of urticaria increased with age,and positively correlated with parents' educational level (rs =0.96,P =0.000).Children born in urban areas showed higher prevalence of urticaria than those in rural areas (8.79％ vs.5.56％,x2 =13.98,P =0.000).Conclusions The prevalence of urticaria has increased among children aged 2-6 years in recent years.More studies should be carried out to investigate into the pathogenesis and relevant factors of urticaria,so as to facilitate its prevention and treatment.
