摘要

Objective To investigate the infection status of pre-school children in Xinxiang city.Methods The method of adhesive cellophane anal swab with round-bottom tube was used to detect the eggs.A total of 994 samples were collected at 7∶30-9∶30 a.m.in 5 kindergartens (3 in suburb,2 in urban) which were chosen at random.Eggs data were collected,the infection rates were calculated and x2 analysis was used for the infection rate comparing.Results The total pinworm infection rate was 4.93％ (49/994).The pinworm infection rate was 4.71％ (25/531) for boys,and 5.18％ (24/463) for girls with no significant difference.The pinworm infection rate of the children in 2-3 years old group was 3.17％(17/536) and 6.99％ (32/458) in 4-6 years old group with significant difference (x2=7.71,P ＜ 0.05).The pinworm infection rate was 5.77％(14/387) in suburb and 3.62％(35/607) in urban with no significant difference.Conclusion The pinworm infection rate of pre-school children in Xinxiang City now is lower than the average level of China.And the pinworm infection rate is closely related with the children ages.%目的 了解新乡市学龄前儿童蛲虫感染情况,为蛲虫病防治提供依据. 方法 随机抽取新乡市城区2所、郊区3所幼儿园,采用透明胶纸肛拭法于上午7:30～9:30对994名学龄前儿童进行蛲虫感染情况调查,以检获虫卵者为阳性,计算感染率,感染率的比较采用x2分析. 结果 受检儿童蛲虫总感染率为4.93％(49/994).男童感染率为4.71％(25/531),女童感染率为5.18％ (24/463),二者差异无统计学意义;2～3岁组感染率为3.17％(17/536),4～6岁组感染率为6.99％ (32/458),二者差异有统计学意义(x2=7.71,P＜0.05);郊区感染率为5.77％(14/387),城区感染率为3.62％(35/607),二者差异无统计学意义. 结论 新乡市学龄前儿童的蛲虫感染率为4.93％,儿童蛲虫感染率与年龄有关.
