摘要
目的:了解学生人群乙肝病毒携带情况。方法:采用随机抽样的方法,对3个年度、3个区域的小学生、初中学生共计9338人进行HBsAg检测。结果:1997年、2002年、2007年学生人群HBsAg阳性率分别为6.90%、4.57%、3.30%,年度间学生HBsAg阳性率差异有高度显著性(2χ=44.43,P<0.01);县城、东部农村、西部农村学生人群HBsAg阳性率分别为2.98%、3.99%、7.80%,区域间学生HBsAg阳性率差异有高度显著性(2χ=86.28,P<0.01);检测小学校学生和初中学校学生HBsAg阳性率分别为3.53%、6.32%,两者差异有高度显著性(2χ=38.7,P<0.01)。结论:检测3个年度、10年来学生人群HBsAg阳性率呈下降趋势;县城学生HBsAg阳性率低于东部、西部农村学生;初中学校学生HBsAg阳性率高于小学校学生。
Objective ：To investigate the presence of hepatitis B virus in our county＇s student population. Methods： HBsAg was tested among a total of randomly sampled 9338 primary and junior middle school students from three different areas in 3 years. Results：The positive rates of HBsAg among the students in the years of 1997, 2002 and 2007 were respectively 6. 90%, 4.57% and 3.30. The differences between the years showing a high significance level （χ^2 =44. 43, P 〈0. 01 ） ;its positive rates among the students from the county seat and rural areas in the east and west of the county were 2. 98%, 3.99% and 7.80% , indicating a high significance level between the regions（χ^2= 38.7, P 〈0.01 ）. The positive rates of 3. 53% and 6. 32% between the primary student group and the middle school student group also pointed to a high level of significance （χ^2 = 38.7, P 〈0. 01 ）. Conclusion ：The tests conducted in three different years show that over the past ten years the positive incidence of HBsAg has declined and that the incidence is lower among students in the county seat than among those in rural areas and higher among junior high school students than among primary school students.
