Abstract:
[Objective] To identify the environmental factors of diarrhea in Sichuan rural areas during summer, and to provide basis and support for intervention measures.
[Methods] During July to August 2011, information on demographic characteristics, drinking water, types of lavatory, and diarrhea incidences were collected from 4 995 households of 1 040 administrative villages of 52 counties by stratified and random sampling. Stata 12.0 was used for logistic regression analysis.
[Results] Diarrhea occurred in 7.95% of the households investigated. The results of multivariate logistic regression analysis indicated that obtaining drinking water from ditch/pond/canal/river (OR=1.535, P=0.028), drinking unboiled water (OR=1.738, P=0.005) or purified water (OR=1.434, P=0.001), and vectors in living environment (OR=1.260, P=0.049) were the risk factors of diarrhea.
[Conclusion] The main impact factors of summer diarrhea in the rural areas of Sichuan Province are drinking water in ditch/pond/canal/river, drinking unboiled water or purified water, and vectors in living environment.
