摘　　要：目的了解湖南省涟源市人体肠道寄生虫病感染状况及其影响因素,为制订合理的寄生虫病防治措施提供参考依据。方法按照《湖南省人体重要寄生虫病现状调查实施细则》的要求和方法,分层整群抽取4个乡镇进行人体重点寄生虫感染情况调查,采用改良加藤法检查虫卵。结果共调查1 133人,感染者53人,总感染率为4.68%,蛔虫是主要感染虫种;年龄、性别肠道寄生虫感染率差异无统计学意义;农业人口(χ2=8.493,P=0.004)、学历较低(χ2=9.20,P=0.01)、饮用井水或河水(χ2=7.98,P=0.02)、便后不洗手(χ2=6.50,P=0.04)及未使用无害化厕所(χ2=4.11,P=0.04)是人体肠道寄生虫感染的危险因素。结论蛔虫是当地人体肠道寄生虫感染的主要虫种。应加强针对低学历、卫生习惯/卫生设施较差的重点人群、重点地区的寄生虫病的综合防治工作。Objective To investigate the status of human parasitic infections and the influencing factors in Lianyuan,Hunan Province,and to provide reference for rational developing prevention and treatment measures of parasitic diseases. Methods According to the Implementation Regulations for Survey on Current Status of Human Important Parasitic Diseases,investigations about the status of human important parasitic infections were performed among residents of 4 towns in Lianyuan,Hunan Province.The Kato-Katz method was used to detect parasite eggs. Results Investigations were performed on 1,133 residents,with a total parasitic infection rate of 4.68%（53/1,133）,and the main parasite species is ascarid.No statistically significant diffidence was found in the parasitic infection rate among different age-groups and between different genders.Single factor analysis indicated that farming population（χ2=8.493,P=0.004）,lower educational level（χ2=9.20,P=0.01）,non-purified water drinking（χ2=7.98,P=0.02）,seldom washing hands after a bowel movement（χ2=6.50,P=0.04） and without harmless toilet（χ2=4.11,P=0.04） were the risk factors for parasitic infections. Conclusions The main parasite species is ascaris among people in Lianyuan.More attention should be paid to implementing comprehensive prevention and treatment measures among people with lower educational backgrounds,poor hygienic habits and poor sanitary facilities.
