目的了解昭平县在校中小学生的HBsAg感染情况,为乙型肝炎的防控提供科学的依据。方法用酶联免疫法(ELISA法)对所采集的血样进行HBsAg项目测定,结果判断按试剂说明书进行。结果共对43 217名在校中小学生进行检测,HBsAg阳性率为2.55%,其中男生阳性率为3.11%,女生阳性率为1.95%,男生与女生的阳性率差别有统计学意义(χ2=62.68,P<0.01),中学生阳性率为4.48%,小学生阳性率为1.34%,中学生和小学生的阳性率差别有统计学意义(χ2=441.6,P<0.01),乡镇学生阳性率为3.14%,县直学生阳性率为0.76%,乡镇学生与县直学生的阳性率比较有统计学意义(χ2=487.0,P<0.01)。结论昭平县在校中小学生HBsAg感染水平是比较低的,但还必须认识到乙型肝炎的危害性,要加强乙肝防控知识的宣传,正确注射乙肝疫苗是预防乙肝感染的重要手段。
Objective To understand HBsAg infection among primary and secondary school students in Zhaoping County and provide a scientific basis for the prevention and control of hepatitis B. Methods Enzyme - linked immunosorbent assay (ELISA) was used to measure the HBsAg of the collected blood samples. The results were judged according to the instructions of the reagent. Results A total of 43 217 primary and secondary school students were tested. The positive rate of HBsAg was 2.55%. The positive rate of boys was 3.11%, the positive rate of girls was 1.95%, the positive rate of boys and girls was statistically different (χ2 = 62.68 , P <0.01). The positive rate of middle school students was 4.48%, the positive rate of primary school students was 1.34%, the positive rate of middle school students and primary school students was statistically different (χ2 = 441.6, P <0.01), the positive rate of township students was 3.14% The positive rate of straight students was 0.76%. The positive rates of township students and county students were statistically significant (χ2 = 487.0, P <0.01). Conclusion The level of HBsAg infection among primary and secondary school students in Zhaoping County is relatively low. However, it is still necessary to recognize the harmfulness of hepatitis B and to promote the publicity of hepatitis B prevention and control knowledge. Proper injection of hepatitis B vaccine is an important means to prevent hepatitis B infection.
