摘要
本文对饮水卫生已普及的农村,以人群为基础进行1∶2配比病例对照研究,共选入195病例,在配合条件 Logistic 回归模型中采用各项因素多水平分析法探讨同一地区不同季节腹泻病的危险因素。结果表明,冬春季有4个危险因素,而夏季增至9个因素。归纳为用水卫生(用河水洗菜、洗碗、洗抹布及刷牙),个人卫生(饭前便后不洗手),饮食卫生(剩菜不置于碗橱和食前不回锅),餐室有蝇等。说明同一地区不同季节本病危险因素不同,夏季多于冬春季。控制本病对策不能仅限于饮水卫生,还要重视用水卫生、个人和家庭卫生以及饮食卫生。
In this paper a population-based 1:2 matched study of 195 pairs on diarrhoeal disease was conducted in rural areas that have been impr- oved in water sanitation.Multiple conditional logistic regression technique with the discrete variables under study taking multiple was used in data analysis to compare the risk factors on different seasons in the same region.It was showed that diarrhoea was significantly assoc- iated with lack of handwashing after defecation, cleaning wiper with surface water,using wiper to clean the bowls and chopsticks and lack of cleaning cupboard in winter and spring seasons. In summer the risk factors increased in 9 fact- ors.There were lack of handwashing before dinner and after defecation;cleaning vegetable, wiper,dinner things and teeth with surface water;leftovers absence to lay up in the cupb- oard and cook again before dinner;presence flies in dinning room.These results suggest the importance of the health education programe to prevent the incidence of the disease while the water sanitation has been performed in such areas.
