[目的]了解天津市红桥区食品行业、公共场所行业从业人员HBsAg、HBeAg携带情况,更好地为食品和公共场所的卫生监督提供依据。[方法]2006～2009年在天津市红桥区卫生防病站进行健康体检的食品、公共场所从业人员,每人空腹静脉采血5～10ml,分离血清,采用酶联免疫吸附试验(ELISA)检测HBsAg、HBeAg。[结果]2006～2009年共检测食品和公共场所从业人员89715人,HBsAg阳性检出率为3.02%,HBsAg、HBeAg双阳性检出率为1.05%。年度之间有显著性差异,2009年HBsAg、HBeAg阳性率均比2006～2008年的HBsAg、HBeAg阳性率有所降低(χ2=18.719,P﹤0.01;χ2=19.031,P﹤0.01);2009年各年龄组HBsAg阳性率差别无统计学意义(χ2=6.962,P=0.138),而各年龄组HBeAg阳性率随年龄增长而下降(χ2=80.830,P=0.000)。[结论]天津市红桥区食品、公共场所从业人员HBsAg阳性率为3.02%,远远低于全国平均水平(9.78%),建议加强食品及公共场所的卫生监督的力度,做好宣传教育及岗前卫生知识培训和健康体检工作,重点监督和保护17～30岁人群,并对易感人群进行乙肝疫苗接种。
[Objective] To understand the situation of HBsAg and HBeAg carried by employees in food industry and public places in Hongqiao District of Tianjin and to provide the basis for health supervision of food and public places. [Methods] From 2006 to 2009, employees in food and public places who took health examination in Sanitary and Anti-disease Station of Tianjin Hongqiao District took 5 ~ 10ml of blood per person from the fasting venous blood separately. The serum was detected by enzyme-linked immunosorbent assay (ELISA) HBsAg, HBeAg. [Results] There were 89,715 employees in food and public places from 2006 to 2009, the positive rate of HBsAg was 3.02%, and the positive rate of HBsAg and HBeAg was 1.05%. There was a significant difference between the year and 2009, HBsAg, HBeAg positive rate than in 2006 ~ 2008 HBsAg, HBeAg positive rate decreased (χ2 = 18.719, P <0.01; χ2 = 19.031, P <0.01); 2009 There was no significant difference in the positive rate of HBsAg in all age groups (χ2 = 6.962, P = 0.138), while the positive rate of HBeAg in all age groups decreased with age (χ2 = 80.830, P = 0.000). [Conclusion] The HBsAg positive rate of employees in food and public places in Hongqiao District of Tianjin was 3.02%, far lower than the national average (9.78%). It is suggested to strengthen the hygiene supervision of food and public places, to do well in publicity and education Pre-job health knowledge training and health examination, focusing on monitoring and protection of 17 to 30-year-old population, and susceptible populations for hepatitis B vaccination.
