A cross-sectional survey was conducted by using a questionnaire among grade 3 to 5 students in a school in Xuhui Districtï¼ Shanghaiï¼ in September 2013 and 2020ï¼ respectively. The questionnaire collected variables including living environmentï¼ daily habitsï¼ family history of respiratory and allergic diseasesï¼ and incidence of these diseases in children.

Logistic regression was conducted to determine the influencing factors.ResultsA total of 1 398 valid questionnaires were collected ï¼705 in 2013 and 693 in 2020ï¼. Compared with 2013ï¼ annual average concentrations of PM2.5ï¼ PM10ï¼ O3ï¼ SO2ï¼ and NO2 in 2020 significantly decreased. The prevalence of bronchial asthmaï¼ bronchitisï¼ persistent cough and persistent expectoration in 2013 were significantly higher than those in 2020 ï¼P<0.05ï¼ in Xuhui District. Multivariate analysis showed that severe air pollutionï¼ boysï¼ parents with asthma or allergyï¼ parents with higher educational levelsï¼ and more allergens in household were the risk factors associated with the incidence of bronchial asthmaï¼ bronchitisï¼ allergic rhinitis and atopic eczema ï¼P<0.05ï¼. Parents with allergy historyï¼ high smoking frequency of family memberï¼ and more allergens in household were the risk factors associated with the incidence of persistent cough and persistent expectoration ï¼P<0.05ï¼.ConclusionTo 2013ï¼2020 air pollution in Shanghai has been mitigated and prevalence of bronchial asthma and bronchitis of children has decreased.
