东莞市桥头镇7种职业人群HBsAg流行情况分析

Epidemic Situation of HBsAg among 7 Types of Occupational Populations in Qiaotou County of Dongguan City

目的探讨HBsAg阳性与不同职业人群的关系，为进一步防治乙型肝炎提供依据。方法选取在东莞市桥头镇生活、工作和学习2a以上，2004年参加预防性和职业性体检的7种不同职业的5800人的HBV血清学检测结果进行统计分析。结果职业人群中HBsAg阳性率为13．84％；7种不同职业人群中，HBsAg阳性率较高的为接触生产性粉尘的工人（21．45％）和接触有机溶剂的人群（18．95％），在校师生最低（6．30％）；HBsAs阳性率男性高于女性（x^2=24．838，P〈0．001）；年龄分布以20．29岁组HBsAg阳性率最高（15．48％），0—9岁组最低（3．64％）；HBsAg阳性者HBV感染模式有9种，以“大三阳”最多（37．73％）；其次为“小三阳”（36．49％）。结论桥头镇7种职业人群HBsAg阳性率高，且感染情况复杂，应进一步加强乙肝防治工作，特别是要加强高危人群的健康监护和行为干预。

[ Objective] To investigate the correlation between HBsAg positive and different occupational populations and provide basis for hepatitis B prevention. [Methods] HBV serological examination was conducted on 5 800 people of 7 different occupations who had been living in Qiaotou County for over 2 years, statistic analysis was made on the result. [Results] The total HBsAg positive rate was 13.84% ; higher HBsAg positive rates were among dust- exposed workers （21.45%） and organic solvent- exposed population （ 18.95% ）, while that of the teachers and students were the lowest （6.30%）. HBsAg positive rate of males was higher than that of females （x^2 = 24. 838, P 〈 0.001）. According to the age distribution, HBsAg positive rate was the highest among the group of 20 to 29 （ 15.48 %） and the lowest among the group of 0 to 9 （3.64% ）. There were nine types of HBV infection models among positive HBsAg carriers, among which HBsAg, HBeAg,HBcAb occupied 37.73% in the first place and HBsAg,HBeAb, HBcAb occupied 36.49 % the second. [Conclusion] The HBsAg positive rate among the 7 different occupational populations was rather high and complicated, which requires more solid preventive work, health supervision and interference.
