Abstract: Objective　To investigate the prevalence and influencing factors of Enterobius vermicularis infections among children in Fanxian County, Henan Province in 2019, so as to provide insights into the management of enterobiasis. Methods　Five kindergartens were selected in urban and rural areas of Fanxian County, Henan Province using the stratified sampling method in 2019, and a census of E. vermicularis infections was performed among all children in the kindergartens. E. vermicularis eggs were detected using adhesive and scotch cellophane⁃tape anal swab methods, and the basic characteristics of children and their families, health habits and the kindergartens’ information were investigated with questionnaires. Logistic regression analysis was used to investigate the risk factors and protective factors of pinworm infection in children. Results　A total of 671 children were tested, and the mean prevalence of E. vermicularis infections was 15.50% (104/671). The prevalence of E. vermicularis infections was higher among children in rural kindergartens (28.13%, 72/256) than in urban kindergartens (7.71%, 32/415) ([χ2] = 50.380, P < 0.01), and greater in private kindergartens (32.26%, 60/186) than in public kindergartens (9.07%, 44/485) ([χ2] = 55.183, P < 0.01). There was no gender⁃specific prevalence of E. vermicularis infections among children ([χ2] = 1.442, P > 0.05), and the prevalence of E. vermicularis infections presented a tendency towards a rise with age ([χ2] trend = 8.373, P < 0.05) and school grade ([χ2] trend = 30.274，P < 0.05). Logistic regression analysis identified rural kindergartens and high grades as risk factors, and separate washing of children’s and adults’ cloths, frequent bathing and frequent dinnerware disinfection in kindergartens as protective factors for E. vermicularis infections among children. In addition, there was no significant difference in the detection of E. vermicularis infections among children by using adhesive (73.08%, 76/104) and scotch cellophane⁃tape anal swab methods (56.73%, 59/104) ([χ2] = 3.959, P > 0.05). Conclusions　The prevalence of E. vermicularis infection is high among children in Fanxian Country, Henan Province. Health education and surveillance of enterobiasis are required to be intensified among children in rural kindergartens and senior grades and their parents and teachers.

摘要： 目的　调查河南省范县儿童蛲虫感染状况并分析影响因素，为蛲虫病防治提供参考。方法　2019年在河南省范县城镇和农村进行分层抽样，共抽取5所幼儿园。对全体在园儿童采用胶贴肛拭和胶带纸肛拭两种方法进行镜检普查蛲虫卵，同时采用问卷调查收集儿童及其家庭成员基本情况、卫生习惯和幼儿园情况，应用logistic回归分析调查儿童蛲虫感染的危险因素和保护因素。结果　共调查671名儿童，平均蛲虫感染率为15.50%（104/671）。农村幼儿园儿童蛲虫感染率为28.13%（72/256），显著高于城镇幼儿园的7.71%（32/415）（[χ2] = 50.380，P < 0.01）；私立幼儿园儿童蛲虫感染率为32.26%（60/186），显著高于公立幼儿园的9.07%（44/485）（[χ2] = 55.183，P < 0.01）；不同性别儿童蛲虫感染率差异无统计学意义（[χ2] = 1.442，P > 0.05），且蛲虫感染率随儿童年龄增大和年级增高均呈上升趋势（[χ2]趋势 = 8.373、30.274，P均< 0.05）。logistic回归分析发现，农村幼儿园和就读年级高是儿童蛲虫感染的危险因素，成人儿童衣服分开洗、儿童勤洗澡和幼儿园餐具勤消毒是保护因素。胶贴肛拭法检测儿童蛲虫感染率为73.08%（76/104），与胶带纸肛拭法检测结果（56.73%, 59/104）差异无统计学意义（[χ2] = 3.959，P > 0.05）。结论　河南省范县儿童蛲虫感染率较高，应加强农村幼儿园和年级较高儿童及其家长和老师等重点人群蛲虫病健康教育和监测。
