Abstract

The frequency of Australian antigen carriers (HBsAg) was studied in three samples from northeastern Brazil. In sample A there were 1000 women from Tsylla Balbino Maternity in Salvador; in sample B there were 1,512 blood donors from Salvador, and in sample C there were 930 blood donors from Aracaju. In sample A, B and C the observed frequency of carriers (HBsAg) was 1.20%, 1.58% and 2.04% respectively. These differences were not significant (x22 = 2.2; p greater than 0.25). There was no association between the carrier state and sex, age, ABO and Rh blood groups, Chagas' disease and rural origin. However, the frequency of carriers (HBsAg) increases from White to Black, as follows: Whites = 0.5%; Mulattoes = 1.91%, and Black = 1.96% (x22 = 7.91; p less than 0.02).

巴西东北部混合人群HBsAg与种族的关系

研究了巴西东北部3份样本中澳大利亚抗原携带者(HBsAg)的频率。在样本A中，有1000名妇女来自萨尔瓦多的Tsylla Balbino产科;样本B中有1512名献血者来自萨尔瓦多，样本C中有930名献血者来自阿拉卡朱。A、B、C样本HBsAg阳性率分别为1.20%、1.58%、2.04%。这些差异不显著(x22 = 2.2;P > 0.25)。携带者的状态与性别、年龄、ABO和Rh血型、恰加斯病和农村血统没有关联。然而，从白人到黑人，携带者(HBsAg)的频率增加，如下:白人= 0.5%;黑白混血儿= 1.91%，黑人= 1.96% (x22 = 7.91;P < 0.02)。
