目的了解劳务人员上岗前乙肝表面抗原(HBs Ag)携带情况及影响因素,为进一步完善乙肝防控措施提供依据。方法采集上岗前体检劳务人员10 980人静脉血样,采用酶联免疫吸附法(ELASA)测定HBs Ag,按年份、年龄和性别进行分析。结果 10 980名劳务人员中HBs Ag总阳性率15.32%(1 682/10 980),其中男性阳性率为15.89%(733/4 611),女性阳性率为14.90%(949/6 369),各年龄组间以30~39岁年龄组阳性率最高,为16.48%(543/3294)。结论近年来乙型肝炎防控工作成效明显,人群中HBs Ag携带者呈逐年减少趋势,但仍处于较高水平。应扩大健康教育面,大力提倡良好卫生习惯,加强成人乙肝疫苗接种,强化免疫屏障。
Objective To understand the situation of HBsAg carriers and the influencing factors before serving in the labors, and to provide basis for further improvement of hepatitis B control measures. Methods A total of 10 980 venous blood samples were collected from pre-job medical workers before the job. ELISA was used to detect HBs Ag by ELASA, and analyzed by year, age and gender. Results The positive rate of HBs Ag in 10 980 laborers was 15.32% (1 682/10 980), the positive rate was 15.89% (733/4 611) in male and 14.90% (949/6 369) in female The highest positive rate was between age groups of 30-39 years, 16.48% (543/3294). Conclusion The prevention and control of hepatitis B has achieved remarkable results in recent years. The carriers of HBsAg in the population showed a decreasing trend year by year, but still at a relatively high level. Should expand the health education, vigorously promote good health habits, strengthen adult hepatitis B vaccination, strengthen the immune barrier.
