摘　　要：目的了解山东省儿童蛲虫感染现状及变化趋势,为调整和制订蛲虫病防控策略提供科学依据。方法2016-2020年,在山东省以县为单位设立51个土源性线虫病监测点,对3~9岁儿童采用改良加藤厚涂片法和透明胶纸肛拭法检测蛲虫感染,对检测结果进行描述性分析。结果2016-2020年,山东省在51个土源性线虫病监测点累计检测5060名3~9岁儿童,蛲虫感染率为2.23%,逐年感染率分别为3.99%(26/651)、1.70%(14/824)、0.96%(8/837)、2.90%(45/1552)和1.67%(20/1196),差异有统计学意义(χ^(2)=21.455,P<0.01)。鲁中、鲁东、鲁南和鲁北地区儿童蛲虫感染率分别为1.25%(15/1198)、1.85%(14/755)、3.18%(84/2640)和0(0/467),差异有统计学意义(χ^(2)=27.326,P<0.01);男、女童蛲虫感染率分别为1.98%(56/2831)和2.56%(57/2229),差异无统计学意义(χ^(2)=1.916,P>0.05);不同年龄儿童蛲虫感染率差异有统计学意义(χ^(2)=16.448,P<0.05),其中6岁儿童感染率最高(3.18%,25/786)、3岁儿童感染率最低(0.75%,6/800)。结论2016-2020年山东省3~9岁儿童蛲虫感染率整体维持在中等水平,在省内存在地区分布差异,需采取综合性防治措施加以控制。Objective To investigate the prevalence and changing trend of Enterobius vermicularis infections among children in Shandong Province,so as to provide the scientific evidence for the adjustment and development of the enterobiasis control strategy.Methods Soil-borne nematodiasis surveillance sites were assigned in 51 counties(districts,cities)in Shandong Province from 2016 to 2020,and the E.vermicularis infections were detected using a modified Kato-Katz technique and the cello phane tape method among children at ages of 3 to 9 years living in these surveillance sites.The epidemiological profiles of E.vermicularis-infected children were descriptively analyzed.Results A total of 5060 children at ages of 3 to 9 years were detected in 51 soil-borne nematodiasis surveillance sites in Shandong Province from 2016 to 2020,and the overall prevalence of E.vemicularis infections was 2.23%.The annual prevalence of E.vermicularis infections was 3.99%(26/651),1.70%(14/824),0.96%(8/837),2.90%(45/1552)and 1.67%(20/1196)from 2016 to 2020,respectively,with a significant difference detected among years(χ^(2)=21.455,P<0.01).The prevalence of E.vermicularis infections-was 1.25%(15/1198),1.85%(14/755),3.18%(84/2640)and 0(0/467)among children from central,eastern,southern and northern Shandong Province(χ^(2)=27.326,P<0.01).In addition,there was no significant difference in the prevalence of E.vennicularis infections between male(1.98%,56/2831)and female children(2.56%,57/2229)(χ^(2)=1.916,P>0.05);however,there was age-specific prevalence of E.vermicularis infec tions among children(χ^(2)=16.448,P<0.05),with the greatest prevalence detected among children at ages of 6 years(3.18%,25/786),and the lowest prevalence seen among children at ages of 3 years(0.75%,6/800).Conclusions The prevalence of E.vermicularis infections remained at a medium level among children at ages of 3 to 9 years in Shandong Province from 2016 to2020,with region-specific prevalence found across the province.An integrated strategy is required for enterobiasis cont
