[目的]了解包头市某高校2007级新生中乙型肝炎病毒(HBV)的感染状况,为今后的防治工作提供依据。[方法]采用ELISA法检测包头市某高校2007级1333名新生血清中HBV的5项血清标志物。同时,对来自于城市和农村学生的HBV感染情况进行比较。[结果]1333名学生中,HBsAg阳性率为6.45%,男生为8.63%,女生为5.10%,男女生之间有统计学差异(χ2=6.48,P﹤0.05);城市HBsAg阳性率4.70%,农村HBsAg阳性率7.62%,城乡学生间有统计学差异(χ2=4.50,P﹤0.05);HBsAg阳性的5种模式中,以大三阳和小三阳为主,分别占31.39%和47.67%。[结论]高校应大力开展学生HBV感染调查工作,对新生及时补种和接种乙肝疫苗,加强对乙肝相关知识的宣传,防止乙肝在校园传播。

[Method] Five serological markers of HBV in 1333 newborn serum of 2007 college in Baotou city were detected by ELISA. At the same time, HBV infection from urban and rural students was compared. [Results] Among 1333 students, the positive rate of HBsAg was 6.45%, male was 8.63%, female was 5.10%, there was a significant difference between male and female students (χ2 = 6.48, P <0.05) The positive rate of HBsAg in rural areas was 7.62%, there was a significant difference between urban and rural students (χ2 = 4.50, P <0.05). Among the five HBsAg positive modes, the positive rates were 31.39% and 47.67% respectively. [Conclusion] Colleges and universities should vigorously carry out investigation of HBV infection among students, promptly replant and inoculate newborn hepatitis B vaccine, strengthen the publicity of relevant knowledge of hepatitis B and prevent the spread of hepatitis B on campus.
