山西省昔阳县乙型肝炎感染标志的血清学研究

对山西省昔阳县471人检测HBsAg、抗-HBs、抗-HBc三项HBV感染标志,其阳性率分别为10.19%、34.61%和19.11%,HBV总感染率为52.65%,表明昔阳县为乙型肝炎高发地区。HBsAg、抗-HBs阳性率和HBV感染率年龄分布呈一特殊模式:均随年龄增长而上升,至30岁年龄组为高峰,后HBsAg阳性率随年龄增长而下降;而抗-HBs阳性率和HBV感染率略有下降,到50岁年龄组又升至一个高峰。HBsAg阳性率农民显著高于干部,HBV感染率也以农民为最高(59.55%)。食品从业人员由于受历次检查的筛选,HBV感染率最低(37.50%);男女性别HBV感染机会相同。分析三项HBV感染标志的传染源作用和HBV感染情况,为制订乙型肝炎防治重点提供了科学依据。

Serological Study about the Infection of Hepatitis B in Xiyang County, Shanxi Provincial Abstract

Authors examined HBsAg, anti-HBs and anti-HBc of 471 people in Xiyang, Shanxi. The positive rate is 10.19%, 34.61% and 19.11% respectively. The total infection rate of HBV is 52.65%. It indicates that Xiyang county is highly infectious area of HB. The age distribution of positive rate of HBsAg, anti-HBs, and the infection rate of HBV present special model: i.e. goes up along with age's growing, up to 30 years old, it gets the high peak. After 30 years old, the positive rate of HBsAg is going down along with the age's growing, the positive rate of anti-HBs and the infection rate of HBV go down a little. The group of 50 years old has a high peak again. The positive rate of HBsAg of peasant is remarkable higher than cadre's. The infection rate of HBV of peasant is the highest, it is 59.55%. The infection rate of HBV of the people who work in food units is lowest, because they are examined regularly. The infection of man and woman is same.
