摘　　要：目的观察常州市肠道线虫病低度流行区干预措施的效果,探索有效的肠道线虫病防控措施。方法选择常州市武进区、金坛市、天宁区3个(市)区居民为监测对象,采用改良加藤法检测肠道线虫,透明胶纸肛拭法检测蛲虫,成本-效果分析法分析肠道线虫病防控的投入与效果。结果共调查26 966人,发现肠道线虫感染者99例,感染率为0.37%。本地人口感染率为0.31%(63/20 267),流动人口感染率为0.55%(37/6 699),前者低于后者(P<0.01);城区人口感染率为0.29%(44/15 328),农村人口感染率为0.47%(55/11 638),前者低于后者(P<0.05)。采用不同干预措施,肠道线虫感染率每下降1%所需成本分别为武进区159.42元/万人、金坛市19.33元/万人、天宁区16.71元/万人。金坛市投入的成本低于武进区,但感染率下降却高于武进区。结论外来流动人口以及偏远农村人口仍是常州市肠道线虫病防控的重点对象。肠道线虫病低度流行区可采取重点人群服药结合基本健康教育的干预措施以降低肠道线虫感染率。Objective To evaluate the effect of control interventions for intestinal nematodiasis in areas with low prevalence,so as to explore the effective measures for the control of intestinal nematode infections in Changzhou City,Jiangsu Province,Chi na.Methods The residents in Wujin,Jintan,Tianning districts were selected as monitor subjects and the infections of intestinal nematodes were investigated with Kato-Katz technique or the transparent tape anal swab method.The results were analyzed statisti cally and the cost-effectiveness was also analyzed.Results A total of 26 966 people were investigated and the total infection rate of intestinal nematodes was 0.37%（99/26 966）.The infection rates of the local residents and floating population were 0.31%（63/20 267）and 0.55%（37/6 699）,respectively,and the former was lower the latter（P 0.01）;the infection rates of urban res idents and rural residents were 0.29%（44/15 328）and 0.47%（55/11 638）,respectively,and the former was lower than the latter（P 0.05）.The 3 jurisdictions used different interventions,and the costs of 1% infection rate drop were 15.9 yuan/thousand peo ple in Wujin District,1.9 yuan/thousand people in Jintan District,and 1.7 yuan/thousand people in Tianning District.The cost in Jintan was lower than that in Wujin,but the infection rate drop in Jintan was more than that in Wujin.Conclusion The floating population as well as the rural residents is still the focus and difficulty of the intestinal nematodiasis control.The deworming and health education are the main interventions in the key population.
