[目的]了解龙岩市人体肠道寄生虫病感染现状,为制定防治对策提供科学依据。[方法]采用分层整群随机抽样方法确定调查点,粪便检查采用改良加藤厚涂片法(Kato-Katz)、蛲虫卵检查采用透明胶纸拭肛法,用Excel建立数据库,用EpiInfo 2000统计分析。[结果]检测5县(市)5乡(镇)24个村6岁以上人群粪便样本共10 056人份,感染率6.6%,其中蛔虫、钩虫、鞭虫感染率分别为1.9%、4.5%、0.5%。感染2种肠道寄生虫32例,复合感染率0.3%,感染人群中轻度感染占87.0%,旱作区人群感染率13.2%,水田种植区人群感染率5.0%。不同性别、职业、年龄、文化程度及不同耕作区人群感染率差异有显著意义,女性人群、儿童、老年人及旱作区居民感染率高于其他人群。儿童蛲虫感染率11.4%(257/2 256)。[结论]龙岩市人体肠道寄生虫感染率比1992年(78.6%)已下降91.7%。
[Objective] To understand the status of human intestinal parasitic infection in Longyan City and provide a scientific basis for making prevention and control measures. [Methods] Stratified cluster random sampling method was used to determine the investigation points. The faeces were examined by Kato-Katz method. The ovipositor was examined with a transparent adhesive tape. The database was created by Excel. EpiInfo 2000 Statistical Analysis. [Results] A total of 10 056 stool samples were collected from 6 villages and 5 villages (5 townships) in 5 counties (cities) and the infection rate was 6.6%. The infection rates of roundworm, hookworm and whipworm were 1.9%, 4.5% , 0.5%. Infected two kinds of intestinal parasites in 32 cases, the composite infection rate was 0.3%, mild infection in infected population accounted for 87.0%, dryland population infection rate of 13.2%, paddy field population infection rate of 5.0%. The differences of infection rates among different sexes, occupations, ages, educational levels and different farming areas are significant. The prevalence of infection among female, children, elderly and dryland residents is higher than that among other groups. The prevalence of pinworm infection in children was 11.4% (257/2 256). [Conclusion] The infection rate of human intestinal parasites in Longyan City has dropped by 91.7% over that of 1992 (78.6%).
