1989年3～9月,应用反向被动血凝(RPHA)法对县城内3所小学和距县城30公里的3所农村小学2492名学生检测了乙型肝炎表面抗原(HBsAg),阳性率为3.17％(79/2492),城镇和农村小学生HBsAg阳性率分别为3.24％(69/2130)和2.76％(10/362),7～10岁和11～14岁HBsAg阳性率分别为3.45％(49/14.17)和2.79％(30/1075)。城镇与农村。不同年龄HBsAg阳性率均无显著差异(x~2=0.2-0.9、P>0.05)。男生和女生的HBsAg阳性率分别为4.2％(54/1303)和2..％(25/1189),男生HBsAg阳性率显著高于女生(x~2=8.44,P<0.01),此结果与方金泉报告的结果一
From March to September 1989, 2492 students from 3 primary schools in the county seat and 3 rural primary schools 30 km from the county were tested positive for hepatitis B surface antigen (HBsAg) using reverse passive hemagglutination (RPHA) 3.17% (79/2492). The positive rates of HBsAg in urban and rural primary school students were 3.24% (69/2130) and 2.76% (10/362) respectively. The positive rates of HBsAg in 7-10 years old and 11-14 years old were 3.45% 49 / 14.17) and 2.79% (30/1075). Town and countryside. There was no significant difference in the positive rates of HBsAg between different ages (x ~ 2 = 0.2-0.9, P> 0.05). The positive rates of HBsAg in boys and girls were 4.2% (54/1303) and 2% (25/1189), respectively. The positive rate of HBsAg in boys was significantly higher than that in girls (x ~ 2 = 8.44, P <0.01) Fang Jinquan results of the report one
