Abstract:
Objective To estimate the prevalence of childhood atopic dermatitis (AD) in Changning District of Shanghai as well as its associated risk factors.
Methods A cross-sectional study was conducted in 2 457 children aged 6-12 years old in a community of Changning District.Questionnaires were distributed asking about children's general information and residential environment and the prevalence of AD.The data were analyzed by univariate and multivariate logistic regressions.
Results The total cumulative prevalence of AD was 11.8%.Younger age,family history of allergic diseasesodds ratio (OR),2.35;95% confidence interval (CI),1.77-3.12,mothers lived in newly decorated homes (NDH)(within 6 months after decoration)1 year before or during pregnancy (1.73,1.25-2.40),children lived in NDH (1.77,1.32-2.38),laminated/wood/carpeting floors (1.62,1.02-2.57),mold in homes (1.72,1.17-2.60),children passive smoking (1.64,1.16-2.33),and use of natural gas/coal gas only for cooking (1.73,1.07-2.81) were independent risk factors for children's AD.
