Abstract:

Objective To understand the infection status of Enterobius vermicularis of children aged 3-12 years and its influ?
encing factors in Chongqing City. Methods One rural county and 1 urban county were selected as investigation areas. The chil?
dren aged 3-12 years of 5 towns from 5 different directions of each county were investigated. About 150 children were investigated
every town. The Enterobius vermicularis eggs of children were detectedbytheadhesivecellophane anal swabmethod.Thechildren’s
parent education levels and personal circumstances of sanitation were investigated by the questionnaire survey. Results
Among 1 592 children investigated，the total infection rate of Enterobius vermicularis was 6.85%. The infection rates of boys and
girls were 6.29% and 7.40%，respectively. The infection rates of rural and urban areas were 12.13% and 2.14%，respectively. The
infection rate in children aged 5-7 years was the highest（13.56%）among all the child aged groups. There were significant differ?
ences for the infection rates of Enterobius vermicularis among children of different aged groups，different areas，different education
levels and occupations of parents，washing hand before meal or not，washing hand after WC or not，different classroom grounds，
and lodging or not（P＜0.01 or P＜0.05）. The multivariate logistic analysis indicated that aged group，different areas，classroom
ground and lodging children were independent risk factors for Enterobius vermicularis infection. Conclusions The infection rate

摘要：

目的了解重庆市3～12岁儿童蛲虫感染情况，并分析其影响因素。方法选择重庆市城区和农村各1个区作为调查点，分别按东、西、南、北、中抽取1个乡（镇、街道），每个乡（镇、街道）抽取150名3～12岁儿童作为调查对象。采用圆底试管透明胶纸肛拭法，定性检查蛲虫卵。同时对其个人卫生情况、父母文化程度等因素进行问卷调查。结果1 592名儿童蛲虫感染率为6.85%，其中男、女性感染率分别为6.29%、7.40%；城区和农村感染率分别为2.14%、12.13%；以5～7岁组感染率最高，为13.56%。不同年龄、地区、父母文化程度和职业、饭前便后是否洗手、教室地面、是否寄托等因素的儿童蛲虫感染率比较，差异均有统计学意义（P＜0.01或P＜0.05）。多因素logistic回归分析显示，年龄、地区、教室地面、儿童寄托情况这4个因素是儿童蛲虫感染的危险因素。结论重庆市农村儿童蛲虫感染率高于城市，低年龄段、寄托、农村地区、教室环境较差的儿童应作为防治重点对象。
