目的了解新疆6~12岁学生包虫病流行病学现状,为制定学生包虫病防治策略提供流行病学资料。方法采用分层抽样的方法对新疆94个县(市)学生进行抽样调查,用ELISA方法测定学生血清包虫Ig G抗体。结果共检查6~12岁学生169 435人,血清Ig G抗体检测阳性者6 145人,平均包虫Ig G抗体阳性率为3.63%,其中男性3.47%(3 053人),女性3.80%(3 092人);不同年龄组中11岁年龄组阳性率最高为3.81%,与平均阳性率之间差异无统计学意义(χ2=2.570,P>0.05);不同族别中学生血清Ig G抗体阳性率之间差异有统计学意义(χ2=958.291,P<0.01),其中维吾尔族学生阳性率最高为5.19%,显著高于平均阳性率(χ2=323.208,P<0.01)。结论新疆包虫病流行区6~12岁学生血清Ig G抗体阳性率仍处于一个相对较高的感染水平,尤其是少数民族学生阳性率高于汉族学生,应加强对学生包虫病防治知识的宣传教育力度,制定相应的预防措施控制包虫病的流行。
Objective To understand the epidemiological status of echinococcosis among students aged 6 ~ 12 in Xinjiang and provide epidemiological data for the development of strategies for preventing and treating echinococcosis in students. Methods By stratified sampling method, 94 counties (cities) in Xinjiang were sampled and Ig G antibodies of hydatid cysts were detected by ELISA. Results A total of 169 435 students aged 6-12 years were examined, 6 145 were positive for serum Ig G antibody, and the average positive rate of IgG antibody was 3.63% (3. 05%) in males and 3.80% (3.80%) in females 092). The highest positive rate was 3.81% in the age group of 11 years among different age groups, with no significant difference from the average positive rate (χ2 = 2.570, P> 0.05). The positive rate of Ig G antibody in different ethnic groups (Χ2 = 958.291, P <0.01). The highest positive rate of Uygur students was 5.19%, which was significantly higher than the average positive rate (χ2 = 323.208, P <0.01). Conclusion The positive rate of Ig G antibody in 6 ~ 12-year-old students in endemic areas of echinococcosis in Xinjiang is still at a relatively high infection level, especially the positive rate of ethnic minority students is higher than that of Han students, so it is necessary to strengthen the knowledge about the prevention and treatment of student hydatid disease Publicity and education efforts to develop appropriate preventive measures to control the prevalence of hydatid disease.
