应用多水平模型分析成都市农村改厕的影响因素

目的了解成都市农村改厕的影响因素。方法于2011年7～8月，采用整群随机抽样的方法在成都市9个开展农村改厕项目县内抽取1134户已改厕农户展开调查，拟合二分类反应变量的两水平logistic回归模型，比较不同特征农户的无害化卫生厕所建设情况，探讨影响农村改厕进程的因素。结果低年龄、教育程度高、家庭儿童数增加、家庭无外出务工人员、卫生行为习惯好、卫生知识得分高等农户有更好的改厕倾向（P〈0.05）。结论改厕劳动力的缺乏、受教育程度较低以及不良的卫生习惯等都对改厕工作的进程带来不利影响。

Objective To explore the influencing factors which affect the process of latrine improvement. Methods From July to August in 2011, 1134 families were studied in 9 project counties where the latrines had been rebuilt. Fitting two-level logistic regression model was used to compare the construction of sanitary latrines among different characteristic groups and explored the factors that affected the process of latrine improvement in rural areas. Results The influencing factors showed that the families had higher intention to improve latrine （P〈0.05）. Those families had such related characteristics as followed, younger members, higher educational levels, more children, without migrant workers, better health habits, higher health knowledge scores.
