目的了解广州市越秀区食品及公共场所从业人员HBV感染状况,为乙型肝炎防治工作提供相关对策。方法对2009年在广州市越秀区疾病预防控制中心体检的食品及公共场所从业人员进行HBsAg及HBeAg检测,检测方法采用酶联免疫法。结果共检测68556名食品及公共场所从业人员,检出HBsAg阳性3694例,阳性率为5.39%,其中男性HBsAg阳性率为6.64%(2179/32835),女性阳性率为4.24%(1515/35721),差异有统计学意义(P<0.01)。检出HBeAg阳性1787例,阳性率为2.61%,其中男性阳性率为3.52%(1156/32835),女性阳性率为1.77%(631/35721),差异有统计学意义(P<0.01)。HBsAg与HBeAg阳性率均为16～19岁年龄组最高,分别为7.32%、5.52%,不同年龄组的HBsAg阳性率和HBeAg阳性率差异均有统计学意义(均P<0.01)。结论广州市越秀区食品及公共场所从业人员HBV感染状况处于一般水平。建议采取健康教育与健康促进等措施逐步降低HBsAg携带率。
Objective To understand the status of HBV infection in food and public places in Yuexiu District of Guangzhou City and to provide relevant countermeasures for the prevention and treatment of hepatitis B. Methods HBsAg and HBeAg were detected in food and public places in 2009 in Yuexiu District of Guangzhou Center for Disease Control and Prevention by enzyme-linked immunosorbent assay. Results A total of 68556 HBsAg-positive patients were detected in 36,556 HBsAg-positive patients with a positive rate of 5.39%. The positive rate of HBsAg in male was 6.64% (2179/32835) and the positive rate in female was 4.24% (1515/35721) , The difference was statistically significant (P <0.01). The positive rate of HBeAg was detected in 1787 cases (2.61%). The positive rate was 3.52% (1156/32835) in male and 1.77% (631/35721) in female. The difference was statistically significant (P <0.01). The positive rates of HBsAg and HBeAg were highest in the age group of 16-19 years old, which were 7.32% and 5.52% respectively. There were significant differences in HBsAg positive rate and HBeAg positive rate among different age groups (all P <0.01). Conclusion The prevalence of HBV infection in food and public places in Yuexiu District of Guangzhou City is in the general level. Proposed to take health education and health promotion and other measures to gradually reduce the carrier rate of HBsAg.
