目的了解广东省清远市清城区儿童蛲虫感染及分布现状,为防治蛲虫病提供科学依据。方法采用分层随机抽样的方法,抽取26所幼儿园,采用透明胶纸肛拭法检查蛲虫卵,建立Excel数据库并进行统计分析。结果共检查6 109人,检出蛲虫感染者354人,感染率为5.79%。以幼儿园为单位感染率最高的达16.90%(24/142)。男童感染率为5.77%(193/3 347),女童感染率为5.83%(161/2762),不同性别儿童蛲虫感染率差异无统计学意义(χ2=0.01,P=0.917);大、中、小班儿童蛲虫感染率分别为8.25%(221/2678)、5.27%(107/2030)和1.86%(26/1401),差异有统计学意义(χ2=70.47,P<0.05)。市中心区、市郊及乡镇幼儿园儿童蛲虫的感染率分别为1.86%(53/2843),9.30%(165/1774)和9.12%(136/1492),差异有统计学意义(χ2=150.55,P<0.05)。大、中、小规模托幼机构儿童的蛲虫感染率分别为3.68%(87/2366)、6.25%(161/2578)和9.10%(106/1165),差异有统计学意义(χ2=43.69,P<0.05)。结论广东省清远县清城区幼儿园儿童蛲虫感染率较低,但病例分布不平衡,今后防控重点应放在乡镇和城区一些环境条件和卫生设施较差的幼儿园,采取综合防治措施,降低蛲虫感染率。
Objective To understand the prevalence and distribution of pinworm infection in Qingcheng District, Qingyuan City, Guangdong Province, and to provide a scientific basis for the prevention and control of enterobiasis. Methods Taken stratified random sampling method, 26 kindergartens were taken, and the ovum eggs were examined by the transparent adhesive tape anal swab method. The Excel database was established and analyzed statistically. Results A total of 6 109 people were examined, and 354 people with pinworm infection were detected. The infection rate was 5.79%. In kindergarten, the highest infection rate was 16.90% (24/142). The infection rate of boys was 5.77% (193/3 347) and that of girls was 5.83% (161/2762). There was no significant difference in the prevalence of pinworm among children of different sex (χ2 = 0.01, P = 0.917) The prevalence rates of pinworm in middle and small class children were 8.25% (221/2678), 5.27% (107/2030) and 1.86% (26/1401), respectively. The difference was statistically significant (χ2 = 70.47, P <0.05). The prevalence of pinworm infection was 1.86% (53/2843), 9.30% (165/1774) and 9.12% (136/1492) respectively in urban centers, suburbs and township kindergartens, with significant differences (χ2 = 150.55, P <0.05). The prevalence rates of pinworm infection were 3.68% (87/2366), 6.25% (161/2578) and 9.10% (106/1165) respectively in children from large, medium and small nurseries, the difference was statistically significant (χ2 = 43.69 , P <0.05). Conclusions The prevalence of pinworm in kindergartens of Qingcheng District, Qingyuan District, Guangdong Province is relatively low, but the distribution of cases is not balanced. In the future, the focus of prevention and control should be placed on kindergartens with poor environmental conditions and sanitation facilities in villages and towns, and comprehensive prevention and control measures should be taken to reduce them Worm infection rate.
