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.
