Abstract:

Objective To study the risk factors of schistosomiasis related to household economic condition and individual behavior in marshland and lake regions, so as to provide evidences for schistosomiasis control. Methods Six villages were sampled with the stratified cluster sampling method, 2 339 villagers from 1 247 households were surveyed by a questionnaire and meanwhile their sera were assayed for schistosomiasis by IHA. The Logistic regression was used to analyze the relationship between the results of serological examinations and risk factors. Results The Logistic regression model fitted well (R2 =0.598 4) and it indicated that there existed a regressive relationship between the antibody positive rate and the endemic situation of village, family economic status, age, education level and infection history of schistosomiasis. Conclusion Suitable measures should be made in according to the local economic situation, endemic type and population to control the transmission of schistosomiasis effectively.

摘要：

目的 研究湖沼型流行区血吸虫病的家庭和个人行为影响因素， 为血防工作提供参考。 方法 采用分层整群随机抽样的方法抽取6个村， 开展问卷调查的同时对调查对象采用间接血凝试验进行血吸虫病血清学检测。应用多因素Lo? gistic回归分析血吸虫病血清学结果与相关变量的关系。 结果 共调查1 247户2 339人。Logitic回归模型拟合较好 （R2 = 0.598 4）， 模型提示不同流行程度的村、 家庭经济状况、 村民年龄、 文化程度及血吸虫感染史与日本血吸虫病抗体阳性率有回归关系。 结论 为有效控制血吸虫病疫情， 应结合当地经济发展， 针对不同流行区、 不同防治人群采取适宜的防治措施。
