Abstract:
Objective To compare the differences in the incidence of adverse pregnancy outcome in different area,and confirm if the incidence of adverse pregnancy outcomes is closely associated with air pollution.Methods A cross-sectional study was conducted in the central urban area and the rural-urban area of Xi'an through a questionnaire survey conducted among the local reproductive women selected through multistage stratified random sampling during 2010-2013,all the reproductive women surveyed were in pregnancy or had definite pregnancy outcomes.Results The annual average of SO2 concentration in the central urban area was 38-54 μg/m3,higher than that in the rural-urban area (29-43 μg/m3).The annual average NO2 concentration in the central urban area was 29-87 μg/m3,higher than that in the rural-urban area (22-42 μg/m3).The incidence of birth defects was higher in the central urban area than in the rural-urban area (2.1％ vs.1.0％),the difference was significant (P＜0.05).After adjusting for confounding factors,logistic regression analysis showed the incidence of birth defects in the central urban area was still significantly higher than that in the rural-urban area,the difference was significant (P＜0.05).Conclusion The incidence of adverse pregnancy was closely associated with the level of air pollution.
