某地区中小学生HBsAg检出状况分析

Analysis on the detection results of HBsAg in middle and primary school students in an area

目的了解某地区中、小学生乙型肝炎表面抗原（HRsAg）检出状况，为乙型肝炎的预防控制工作提供依据。方法采用酶联免疫吸附试验（ELISA）对全区7280名中、小学生进行HBsAg检测，并进行流行病学分析。结果该区中、小学生HBsAg总检出率为7．01％；4～7岁学生检出率为3．04％，8～11岁学生检出率6．90％，12～15岁学生检出率8．72％，三组比较，差异有高度显著性（X^2=22．88，P〈0．01）；男生检出率为7．27％，女生检出率为6．70％，两组差异无显著性（F=0．09，P〉0．05）；城区学生检出率为5．92％，农村学生检出率为8．05％，两组差异有高度显著性（X^2=12．08，P〈0．01）。结论该区农村中、小学生HBsAg检出率较高，加强农村中、小学生乙型肝炎防治工作是当前疾病预防控制工作的重点之一。

Objective To evaluate the detection results of HBsAg in middle and primary school students in an area, so as to provide basis for the prevention and control of hepatitis B. Methods HBsAg was detected among 7 280 middle and primary school students by ELISA, and epidemiological analysis was made. Results The total detection rate of HBsAg was 7. 01%, the detection rate in students between 4～7, 8～11, 12～15 years old was 3. 04%, 6. 90% and 8. 72% respectively, there was significant difference among three groups （X^2 = 22. 88, P〈 0. 01） ; the detection rate in male and female students was 7. 27% and 6. 70% respectively, there was no obvious difference between two groups （X^2 = 0. 09, P〉0. 05）; the detection rate in urban and rural area students was 5. 92% and 8. 05% respectively, there was significant difference between two groups （X^2 = 12. 08, P〈0. 01）. Conclusion The detection rate of HBsAg in rural students is higher, the prevention and control of hepatitis B in rural middle and primary school students is important.
