目的了解日常生活、卫生习惯对学龄前儿童肠道线虫感染率的影响。方法于2006年4~6月对杭州市区14所幼儿园共1932名3~6岁儿童进行肠道线虫感染的调查,采用生理盐水直接涂片法和饱和盐水浮聚法粪便检查蛔虫卵、钩虫卵和鞭虫卵,透明胶纸肛拭法检查蛲虫卵。并通过问卷表调查了所有受检儿童的生活、卫生习惯。结果受检者中肠道线虫总感染率为12.89%,其中蛲虫占4.35%,蛔虫8.07%,鞭虫0.62%,钩虫0.31%。没有每天洗身换裤、平时嗜咬指甲、家中养宠物的儿童线虫感染率比较高,差异有统计学意义(P<0.05);而儿童每天是否刷牙与线虫感染率差异无统计学意义(P>0.05)。结论良好的生活、卫生习惯有助于降低学龄前儿童肠道线虫的感染率。
Objective To understand the influence of daily life and health habits on the intestinal nematode infection rate in preschool children. Methods A total of 1932 children aged 3-6 years old from 14 kindergartens in Hangzhou city were investigated for intestinal nematode infection from April to June in 2006. The ascaris eggs were examined by normal saline smear and saturated saline flooding method. Egg and whip egg, transparent adhesive tape anal swab test oviposit. And through the questionnaire survey all the children tested living, health habits. Results The total infection rate of midgut nematodes in subjects was 12.89%. Among them, the incidence of pinworm was 4.35%, roundworm 8.07%, whipworm 0.62% and hookworm 0.31%. There is no daily wash and change of pants, nocturnal nail biting, the number of children living with pets at home nematode infection rate is relatively high, the difference was statistically significant (P <0.05); and children’s daily brushing and nematode infection rate difference was not statistically significant (P > 0.05).
