摘要:
目的 了解四川省农村夏季发生腹泻的环境影响因素, 为制订干预措施提供依据和支持。 方法 2011 年7-8 月, 采用分层随机方法, 抽取四川省52 个县1 040 个行政村, 共4 995 户家庭作为随机样本。收集户主基本情况、家庭饮水状况、厕所类型及腹泻发病情况, 并用Stata 12.0 进行logistic 回归分析。 结果 腹泻发病户比例达7.95%。多因素logistic 回归分析结果显示, 饮用沟/塘/渠/河水(OR=1.535, P=0.028), 饮用未煮沸的水(OR=1.738, P=0.005)、桶装纯净水(OR=1.434, P=0.001), 生活环境中存在病媒生物(OR=1.260, P=0.049)等均为腹泻发病的危险因素。 结论 四川省农村2011 年夏季腹泻的主要影响因素为饮用沟/塘/渠/河水, 饮用未煮沸的水、桶装纯净水, 生活环境中存在病媒生物等。 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.
