摘　　要：目的了解山东省烟台市人体重点寄生虫的感染状况, 为制定防治策略和措施提供科学依据。方法根据《全国人体重点寄生虫病现状调查方案》和实施细则, 于2015 - 2019年采取分层整群随机抽样方法, 从烟台市抽取10个县(市、区)的39个自然村作为调查点。调查对象为各调查点居民, 每个调查点人数不少于200人。采用改良加藤厚涂片法(一粪二检)检测肠道蠕虫虫卵;直接涂片法检测肠道原虫滋养体或包囊;3 ~ 9岁儿童加做透明胶纸肛拭法检测蛲虫。采用SPSS 18.0软件进行统计分析, 组间感染率比较采用χ^(2)检验或Fisher确切概率法, 检验水准α = 0.05。结果 2015 - 2019年共调查8 507人, 肠道寄生虫总感染率为1.75%(149/8 507), 未检出原虫, 共检出4种肠道蠕虫, 分别为鞭虫(1.41%, 120/8 507)、蛔虫(0.16%, 14/ 8 507)、蛲虫(0.14%, 12/8 507)、钩虫(0.07%, 6/8 507)。149例蠕虫感染者中, 混合感染者3例, 占2.01%, 均为鞭蛔混合感染。透明胶纸肛拭法检测儿童578名, 儿童蛲虫感染率为1.90%(11/578)。2015 - 2019年肠道寄生虫感染率先上升后下降, 不同年份间比较, 差异有统计学意义(χ^(2) = 469.38, P<0.05)。男性、女性的感染率分别为1.72%(70/4 071)、1.78%(79/4 436), 二者比较差异无统计学意义(χ^(2) = 0.05, P > 0.05)。不同年龄组人群肠道寄生虫感染率比较, 差异有统计学意义(χ^(2) = 23.34, P<0.05);其中≥80岁组最高, 为2.84%(8/282)。不同职业者肠道寄生虫感染率比较, 差异有统计学意义(χ^(2) = 41.71, P<0.05);其中农民感染率最高, 为2.58%(113/ 4 388)。不同文化程度者肠道寄生虫感染率比较, 差异有统计学意义(χ^(2) = 51.91, P<0.05);其中文盲感染率最高, 为4.98%(16/321)。10个县(市、区)中除莱山区外, 均检出寄生虫感染, 感染率最高的为海阳市(10.18%, 102/1 002), 其余县(市、区)均低于1.20%;不同地区感染率比较, 差异有统计学意义(χ^(2) = 43Objective To understand the infection status of key human parasites in Yantai City,Shandong Province,and to provide scientific basis for establishing strategy for prevention and control of the disease.Methods According to the"National Investigation Plan of Human Parasitic Infection Status"and implementation rules,stratified cluster random sampling method was adopted to select 39 survey sites in 10 counties(cities,districts)of Yantai City from 2015 to 2019.The respondents were residents in each survey site,with no less than 200 people in each survey site.The modified garten thick smear method(one fecal two test)and the direct smear method were respectively used to detect the eggs of intestinal worms and the trophozoites or cysts of intestinal protozoa.Besides,the transparent adhesive paper anal swab was used to detect pinworms in children aged 3-9 years.SPSS 18.0 software was used for statistical analysis.Comparison between infection rates was analyzed byχ^(2)test or Fisher's exact probability test with 0.05 of test level.Results A total of 8507 people were investigated from 2015 to 2019.The total infection rate of intestinal parasites was 1.75%(149/8507),and no protozoa was detected.A total of 4 species of intestinal worms were detected,including 1.41%(120/8507)of whipworm,0.16%(14/8507)of ascaris,0.14%(12/8507)of pinworm and 0.07%(6/8507)of hookworm.Among 149 cases of worm infection,3 cases were ascaris and whipworm mixed infection,accounting for 2.01%.The infection rate of pinworm was 1.90%(11/578)in 578 children aged 3-9 years detected by transparent adhesive paper anal swab.From 2015 to 2019,the incidence of intestinal parasites infection first increased and then decreased,the difference was statistically significant(χ^(2)=469.38,P<0.05).The infection rates of male and female were 1.72%(70/4071)and 1.78%(79/4436),respectively,with no significant difference between them(χ^(2)=0.05,P>0.05).There was a significant difference of intestinal parasites infection rate in different age groups(χ^(2)=23.34,P<0.05).T
