目的研究农村饮用水和环境卫生与介水传染病的相关性,为介水传染病的防治提供依据。方法对2006—2007年“中国农村饮用水与环境卫生现状调查”收集的农村饮用水和环境卫生数据与近两周介水传染病发病数据进行Spearman等级相关和多元线性回归分析。结果相关分析表明感染性腹泻发病率与集中式供水覆盖率、水样合格率、垃圾不随意丢弃率、厨房卫生良好率呈负相关(P<0.05);回归分析结果表明感染性腹泻发病率随着集中式供水覆盖率的增加而下降。结论改善的饮用水和环境卫生对控制和减少介水传染病的发生有重要意义。
Objective To study the correlation between drinking water and sanitation in rural areas and waterborne infectious diseases and provide the basis for the prevention and treatment of waterborne infectious diseases. Methods Spearman rank correlation and multivariate linear regression analysis were conducted on the data of rural drinking water and sanitation collected in 2006-2007 and the survey data of the status of drinking water and sanitation in rural China and the incidence of waterborne infectious diseases in recent two weeks. Results Correlation analysis showed that the incidence of infectious diarrhea was negatively correlated with the concentration of water supply coverage rate, the qualified rate of water samples, the random discard rate of garbage and the good rate of kitchen hygiene (P <0.05). The regression analysis showed that the incidence of infectious diarrhea With the increase of centralized water supply coverage decreased. Conclusion Improved drinking water and sanitation are of great importance for controlling and reducing the incidence of water-borne diseases.
