摘要:  于2011年6~8月采用分层整群随机抽样方法,随机抽取西宁市5个调查点,对3周岁以上的常住人口共4 589人进行调查,采用改良加藤氏厚涂片法检查人体肠道土源性线感染情况,透明胶纸肛拭法检查12岁以下儿童蛲虫感染情况。调查结果显示,人体土源性线虫总感染率为3.0%(136/4 589),其中农村最高,为3.8%(123/3 284)。以蛔虫感染为主,其中15~20岁年龄组蛔虫感染率(1.5%,4/264)明显低于60~70岁年龄组(6.9%,23/335)、70岁以上年龄组(5.3%,6/114)和10~15岁年龄组(5.1%,19/372)(P<0.05);学龄前儿童蛔虫感染率(9.5%,12/127)显著高于其他职业人群(P<0.05);不同性别、民族和文化程度人群的感染率差异均无统计学意义(P>0.05)。12岁以下儿童蛲虫感染率仅为0.5%(2/437),出现在城郊地区。

Abstract: Five fields were selected from Xining City by stratified cluster sampling method for the survey. 4 589 people above 3 years old were examined for nematode infections using Kato-Katz method and children under 12 years old were detected for pinworm infection using transparent tape method from June to August in 2011. The results showed that the total nematode infection rate was 3.0% (136/4 589) with the highest of 3.8% (123/3 284) in rural area. The major species was Ascaris lumbricoides, and the infection rate in 15-20 age group was 1.5%  (4/264), which was significantly lower than that of the age groups of 60-70 (6.9%, 23/335), above 70 (5.3%, 6/114) and of 10-15 (5.1%, 19/372)(P<0.05). The prevalence of A. lumbricoides among the preschool children(9.5%, 12/127) was statistically higher than those in other occupation groups (P<0.05), and the infection rate showed no statistical significance by gender, ethnic and degree of education (P>0.05). Pinworm infection in children under 12 years old was only 0.5% (2/437).
