目的了解近年来鹰潭市青少年乙肝病毒的感染状况及动态变化,为防制工作提供依据。方法以酶联免疫吸附试验(ELISA)法,检测2007—2010年鹰潭市大中专院校新招收学生共3 550名的乙肝5项指标,并对检测结果进行分析。结果 2007—2010年HBsAg阳性率分别为18.05%、14.11%、13.41%、7.20%,平均阳性率为13.10%,男女生阳性率分别为14.90%、11.99%,城乡学生阳性率分别为10.17%、13.74%,大专、中专新生阳性率分别为13.50%、12.23%,465名HBsAg阳性学生中HBeAg阳性占57.41%。结论近几年鹰潭市大中专院校新生乙肝感染率虽然总体呈逐年下降趋势,但是感染率还是偏高,防治工作不可松懈,其中以农村生源、男生为乙肝重点感染人群,需重点防治。
Objective To understand the status and dynamic changes of hepatitis B virus infection in adolescents in Yingtan in recent years and provide basis for prevention and control work. Methods Enzyme-linked immunosorbent assay (ELISA) was used to detect 5 indicators of hepatitis B in newly recruited students in Yingtan City from 2007 to 2010, and the results were analyzed. Results The positive rates of HBsAg between 2007 and 2010 were respectively 18.05%, 14.11%, 13.41% and 7.20%, with the average positive rate of 13.10%. The positive rates of male and female were 14.90% and 11.99% respectively. The positive rates of HBsAg in urban and rural areas were 10.17% 13.74%. The positive rates of junior college and secondary technical freshmen were 13.50% and 12.23% respectively. The positive rate of HBeAg in 465 HBsAg positive students was 57.41%. Conclusions In recent years, the infection rate of hepatitis B in new college students in Yingtan City has been declining year by year, but the infection rate is still high and prevention and control work can not be slack off. Among them, rural students and hepatitis B are the major male infectious diseases.
