Abstract:
Objective:To examine the prevalence of allergic diseases in schoolaged children from Shanghai and to explore related factors so as to produce epidemiological data regarding allergic diseases in children.
Methods:Multistage cluster sampling was used to carry out the study in Shanghai from April to June 2019. A total of 10 686 children aged 7-12 years from 17 primary schools participated in the survey. The International Study of Asthma and Allergies in Childhood (ISAAC)Scale was used to evaluate allergic diseases. Multivariate Logistic regression analysis was performed to analyze the related factors.
Results:The overall prevalence of allergic diseases among schoolaged children in Shanghai was 47.0%. A higher prevalence was observed among boys (50.4% vs 43.3% in girls, χ2=54.44, P<0.01). Common allergic diseases included asthma (13.9%), allergic rhinitis (18.2%), and atopic dermatitis (34.3%). The Logistic regression analysis showed that the common risk factors of asthma, allergic rhinitis and atopic dermatitis included the following:male gender (OR=1.52,1.44,1.22); mother has a bachelors degree or above (OR=1.26,1.77,1.84); family history of allergic diseases (OR=2.87,4.24,2.57); only child (OR=1.16,1.28,1.22); curtain cleaning frequency <1 time/month (OR=1.41,1.79,1.77); room not cleaned daily (OR=1.14,1.18,1.20); and dust exposure frequency ≥1 time/month (OR=1.45,1.56,1.42), all P<0.05. These three types of allergic diseases were also associated with unique risk factors that dependent on socialenvironmentalbehavioral factors.
Conclusion:Compared with previous data, the prevalence of allergic diseases among schoolaged children in Shanghai increased significantly in 2019. The related influencing factors involve multiple variables including demographics, environmental exposure and behavior, which warrant further exploration.
