目的了解不同民族大学生乙型肝炎病毒感染情况,为乙肝的预防和治疗提供科学依据。方法以中南民族大学2007级4015名新生和2008级5006名新生作为调查对象;采用酶联免疫吸附法(ELISA)检测乙肝5项,并进行统计学分析。结果2007,2008年的整体HBsAg阳性率为4.59%,男性阳性率为6.22%,明显高于女生的3.11%(P<0.01);壮族(10.29%)、畲族(9.13%)和瑶族(8.04%)学生的HBsAg阳性率较汉族(4.5%)学生约高1倍,差异有统计学意义(壮族、畲族与汉族间P<0.01,瑶族与汉族间P<0.05)。回族(2.97%)、满族(1.61%)学生的HBsAg阳性率较汉族(4.5%)学生低,差异有统计学意义(P<0.05)。结论乙型肝炎病毒感染率在不同民族学生之间存在较大的差异,提示不同民族学生的不同卫生和生活环境条件可能与乙肝病毒的感染率相关。
Objective To understand the prevalence of hepatitis B virus among college students of different nationalities and provide a scientific basis for the prevention and treatment of hepatitis B. Methods 4015 freshmen of 2007 and 5006 freshmen of 2008 from South Central University for Nationalities were enrolled in this study. Five items of hepatitis B were detected by enzyme-linked immunosorbent assay (ELISA) and analyzed statistically. Results The overall positive rate of HBsAg in 2007 and 2008 was 4.59% and the positive rate was 6.22% in male and 3.11% in female (P <0.01) ) Were higher than Han students (4.5%), the difference was statistically significant (P <0.01 for Zhuang, Shezu and Han, and P <0.05 for Yao and Han). The positive rates of HBsAg in Hui (2.97%) and Manchu (1.61%) students were lower than those in Han (4.5%) students (P <0.05). Conclusion The prevalence of hepatitis B virus infection in different ethnic groups is quite different, suggesting that different health and living conditions may be related to the infection rate of hepatitis B virus.
