目的了解西安市服务行业从从业人员乙肝表面抗原(HBsAg)携带状况。方法2006—2008年对服务行业从业人员进行健康检查,HBsAg采用酶联免疫吸附试验(ELISA)法检测,对HBsAg阳性结果进行分析。结果2006—2008年共检查397385人,HBsAg总阳性率为1.3%,阳性率略有下降。男性阳性率为1.74%,女性为1.04%,男性显著高于女性(χ2=355.74,P<0.01)。其他服务行业阳性率高于餐饮、食品饮料加工及公共娱乐场所(χ2=457.07,P<0.01);其他服务行业人员阳性率高于一二线工作人员(χ2=383.68,P<0.01);20～30岁年龄组阳性率为1.65%,高于其他年龄组;45岁以上年龄组阳性率最低,仅为0.64%(χ2=355.40,P<0.01)。各月份HBsAg阳性检出率呈散在状态。结论该市3年的服务行业从业人员HBsAg携带状况调查数据对控制乙肝传播措施的制定与实施有重要意义。
Objective To understand the carrying status of hepatitis B surface antigen (HBsAg) from practitioners in Xi’an service industry. Methods From 2006 to 2008, health workers in the service industry were inspected. HBsAg was detected by enzyme-linked immunosorbent assay (ELISA), and HBsAg positive results were analyzed. Results A total of 397 385 people were examined in 2006-2008. The total positive rate of HBsAg was 1.3%, the positive rate decreased slightly. The positive rate was 1.74% for males and 1.04% for females, significantly higher in males than in females (χ2 = 355.74, P <0.01). The positive rates of other service industries were higher than that of catering, food and beverage processing and public places of entertainment (χ2 = 457.07, P <0.01); the positive rates of other service workers were higher than those of first and second line workers (χ2 = 383.68, P <0.01) The positive rate in the 30-year-old group was 1.65%, which was higher than that in other age groups. The positive rate in the group over 45 years old was the lowest, only 0.64% (χ2 = 355.40, P <0.01). The positive rate of HBsAg in each month was scattered. Conclusion The survey data on the carrying status of HBsAg among service workers in the city for three years are of great significance for the formulation and implementation of measures to control the spread of hepatitis B virus.
