内蒙古自治区人群蛔虫和蛲虫感染的家庭聚集性分析

FAMILY CLUSTERING ANALYSIS ON ASCARIS AND ENTEROBIUS INFECTIONS IN INNER MONGOLIA

用二项分布配合χ２检验方法对７９０４个家庭、３０７１３人进行统计分析。结果表明，本区人群感染最重的蛔虫和蛲虫均有家庭聚集性（经χ２检验，Ｐ＜０．００１）。全区人群蛔虫和蛲虫家庭聚集率分别为５２．０％和２３．６％。不同家庭内人群的蛔虫感染率随家庭人口数增加而升高。人群的蛲虫感染率与家庭人口数无关。不同地理景观带人群的蛔虫和蛲虫感染均有明显的家庭聚集性。这些特征对今后内蒙古地区寄生虫病防治工作提供了科学依据。

A family clustering analysis on Ascaris lumbricoides and Enterobius vermicularis infections was performed in Inner Mongolia covering 30 713 residents from 7 904 families, by using binomial distribution and χ 2 test for significance reckoning. Family clustering rates of 52.0% and 23.6% were displayed respectively for Ascaris and Enterobius infections. Population oriented calculation showed a tendency of increase of infection rate with the upgrading of family members for A. lumbricoides , but not for E. vermicularis .
