采用酶联免疫吸附试验（ＥＬＩＳＡ）法，对田阳县参加健康体检的９９２０名饮食服务行业人员，进行乙型肝炎表面抗原（ＨＢｓＡｇ）、乙型肝炎ｅ抗原（ＨＢｅＡｇ）、血清谷丙转氨酶（ＡＬＴ）、麝香草酚（ＴＴＴ）的检测，结果表明ＨＢｓＡｇ和ＨＢｅＡｇ阳性率分别为１２．９８％和２．８４％；ＡＬＴ和ＴＴＴ异常率为２．６４％，ＨＢｓＡｇ检出率１９９２年最高，１９９５年最低（χ２＝５．８１，Ｐ＞０．０５）；ＨＢｅＡｇ阳性检出率１９９５年最高，１９９３年最低（χ２＝１１．２３，Ｐ＜０．０５），比较有显著性差异；ＴＴＴ、ＡＬＴ异常率１９９２年最低，１９９４年最高（χ２＝４．６２，Ｐ＞０．０５）；城乡ＨＢｓＡｇ、ＨＢｅＡｇ感染率无差异；１８～２７岁感染率最高，４６～６５岁最低；男性感染率比女性高（χ２＝５．４２，Ｐ＞０．０５）。
Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of HBsAg, HBeAg, ALT (ALT) in 9920 food service workers who participated in the health examination in Tianyang County. ) And thymol (TTT). The positive rates of HBsAg and HBeAg were 12.98% and 2.84% respectively. The abnormal rates of ALT and TTT were 2.64% (Χ2 = 5.81, P> 0.05). The positive rate of HBeAg was highest in 1995 and lowest in 1993 (χ2 = 11.23, P <0.05) The ALT abnormal rate was the lowest in 1992 and the highest in 1994 (χ2 = 4.62, P> 0.05). There was no difference in the prevalence of HBsAg and HBeAg between urban and rural areas, the highest infection rate was found between 18 and 27 years old, and the lowest was 46-65 years old. Female high (χ2 = 5.42, P> 0.05).
