目的：阐明云南山区血吸虫病流行与社会经济因素的关系。方法：通过云南４个山区自然村居民的问卷调查资料，对影响血吸虫病流行的有关社会经济因素作单因素及ｌｏｇｉｓｔｉｃ多元回归分析。结果：女性血吸虫病病史率显著高于男性，文化程度、经济收入高者的病史率显著低于文化程度和经济收入低者，防护意识强者病史率低，经常换工的人群病史率亦高。有病史人群接触疫水及野粪的频率均显著高于无病史人群。ｌｏｇｉｓｔｉｃ多元回归分析结果显示，换工、接触沟渠水、菜园地排野粪、生活用沟水和水稻田劳动是影响病史率高低的重要因素；文化程度、经济收入、家畜及使用泉水也是影响病史率的危险因素。结论：云南大山区血吸虫病的流行显然受当地社会经济因素及独特的行为习惯的影响。
Objective: To elucidate the relationship between schistosomiasis prevalence and socioeconomic factors in mountainous areas of Yunnan. Methods: According to the questionnaire survey data of 4 natural villages in mountainous areas in Yunnan Province, single factor and logistic multiple regression analysis were conducted on the socio-economic factors affecting the prevalence of schistosomiasis. Results: The prevalence rate of female schistosomiasis was significantly higher than that of male, with the educational level and economic income being significantly lower than those with lower education level and economic income. . The frequency of exposure to epidemic water and wild feces of people with history was significantly higher than those without history of illness. Logistic multivariate regression analysis showed that labor, exposure to ditch water, sewer dung, life ditches and paddy fields were the important factors influencing the morbidity and mortality rate; educational level, economic income, livestock and the use of spring water also affected the history Rate of risk factors. Conclusion: The prevalence of schistosomiasis in Dashan District of Yunnan Province is obviously affected by the local socio-economic factors and unique behavioral habits.
