对花垣县苗族人群乙型肝炎表面抗原携带情况作抽样调查用反向间接血凝(RPHA)法检测2027人的HBsAg,阳性者482人,携带率为20.81%。不同年龄的携带率差异无显著性(X~2=16.52 df=12p>0.05)。男性阳性率为25.73％,女性阳性率为16.43%(X~2=26.46 df=1 P<0.01),差异极显著。苗族人群HBsAg携带率为21.27％,经统计学处理,苗、汉、土家族之间无显著性差异(X~2=1.02df=3 P>0.05)。以农民携带率高(20.82％),最低为幼儿(4.81％)。
A case-by-case survey on the carrier of Hepatitis B surface antigen in Miao people in Huayuan County was carried out. Reverse transacting hemagglutination (RPHA) was used to detect 2027 HBsAg positive patients, 482 of whom were positive. The carrying rate was 20.81%. There was no significant difference in the carrying rates at different ages (X ~ 2 = 16.52 df = 12p> 0.05). The positive rate of males was 25.73%, the positive rate of females was 16.43% (X ~ 2 = 26.46 df = 1 P <0.01). The difference was significant. The carrying rate of HBsAg in Miao population was 21.27%. There was no significant difference between the Miao, Han and Tujia families (X 2 = 1.02df = 3 P> 0.05) after statistical analysis. To farmers carrying rate is high (20.82%), the minimum for young children (4.81%).
