    Abstract:
    Seroepidemiological investigations on the hepatitis B virus infection were carried out among populations of seven nationalities that could represent the main categories by the language system. The HBsAg prevalence, after sex- and age-adjustment, was 15.3% in Han in contrast, that was 26.2% in Tibetan and 24.0% in Yao, being significantly higher (P < 0.001); and on the other hand, 7.0% in Li and 5.3% in Uygur, being significantly lower than that in Han (P < 0.001). The age peaks of HBsAg prevalence in Uygur and Li declined much earlier than others. HBeAg was not detected in women during childbearing age. The ratios of anti-HBs/HBsAg were between 1.61 and 2.06 in general while they were only 0.82 in Tibetan and 1.09 in Yao.
