目的了解专科学校新生乙肝病毒感染情况,为做好学校乙肝预防控制工作提供理论依据。方法对我市某专科学校2006~2007年1 955名入校新生进行乙肝五项指标检测,并进行统计学分析。结果入校新生HBsAg阳性率为9.46%,男生感染率(10.58%)高于女生(7.8%),有统计学意义;城镇学生阳性率(7.2%)显著低于乡村学生(11.22%)。抗-HBs阳性率为38.25%,其中男生38.95%,其间有统计学意义,女生37.2%,男女间无统计学意义;城镇学生46.52%,乡村学生31.75%(χ2=44.74,P<0.01),乙肝五项指标均阴性者达52.3%。结论该校新生乙肝病毒感染率仍处于较高水平,对这一特殊群体应加强管理,同时开展好易感人群乙肝疫苗预防接种工作。
Objective To understand the situation of hepatitis B virus infection among neonatal college students and to provide a theoretical basis for the prevention and control of hepatitis B in school. Methods The enrollment of 1 955 freshmen from a college in our city from 2006 to 2007 was tested for five indexes of hepatitis B, and statistical analysis was made. Results The positive rate of HBsAg was 9.46% and the prevalence of male students was 10.58% (7.8%). The positive rate of urban students was significantly lower than that of rural students (11.22%). The positive rate of anti-HBs was 38.25%, of which 38.95% were boys. There was a statistically significant difference between the two groups (37.2% for girls and 46.52% for boys and 31.5% for rural students (χ2 = 44.74, P <0.01) Five indicators of hepatitis B were negative 52.3%. Conclusion The hepatitis B virus infection rate of freshmen in this school is still at a high level, so we should strengthen the management of this special group, and carry out vaccination of hepatitis B vaccine in susceptible population at the same time.
