土源性线虫感染家庭聚集性分析

ANALYSIS OF SOIL-BORNE NEMATHELMINTH INFECTIONS CLUSTERING IN FAMILIES

本文目的在于探讨中国农村土源性线虫感染的家庭聚集性及其与社会经济文化因素的关系。其方法是通过安徽省望江县一个村的问卷调查、专题座谈会、深入访谈、实地观察及３年粪便检查，对土源性线虫感染的家庭聚集性作Ｇ检验，并对影响土源性线虫感染的主要社会因素作单因素分析。结果：蛔虫感染和钩虫感染有家庭聚集性，鞭虫感染无家庭聚集性。蛔虫感染与家庭卫生状况显著相关．卫生状况差者的相对危险度是卫生状况好者的６．８８倍。钩虫感染女性高于男性，似与女性在桑地耕作较多有关，而钩虫感染在０—１０岁年龄组和１１—２０岁年龄组为高，似与这两个年龄组赤脚下地较普遍有关。防治土源性线虫感染的根本措施是改善家庭卫生状况和建立良好的卫生习惯。

The objective of the study is to explore the family clustering of soil-borne nemathelminth and its relationship with social-economic,cultural factors in rural China. For this purpose,a house-visiting investigation with a questionnaire concerning social-economic factors,subject group discussions,in-depth interviews,direct observations and three-year stool examinations were conducted in a village in Anhui Province. G-test on clustering in families and single factor analysis on the relationship between social factors and soil-borne nemathelminth infections were used. The results showed that there were household clustering of Ascaris and hookworm infections but no household clustering. in Trichuris infection. The rate of Ascaris infection was higher in inhabitants with poor general family sanitation. The odds ratio(OR)was 6. 88 for inhabitants with poor sanitation, 1. 0 for inhabitants with good sanitation. Hookworm infection rate in female was higher than that in male,which was perhaps due to more work in the mulberry field for women. Hookworm infection rates were also high in age group of 0-10 and 11-20 years old,which perhaps due to barefoot walking habit for young people. The authorS suggested that there was certain relationship between soil-borne nemathelminth transmission and social-economic factors. General family sanitation improvement and health education are the basic measures for soil-borne nemathelminth control program.
