目的了解中国公共服务场所从业人员乙肝表面抗原(HBsAg)阳性率情况,为制定预防策略提供依据。结果不同年份HBsAg阳性率比较有统计学意义差异(χ2=30195,P<0.01),其中2002年最高,为9.57%;2010年最低,为2.75%。不同行业HBsAg阳性率比较有统计学意义差异(χ2=925.6,P<0.01),公共服务行业HBsAg阳性率高于食品行业。各地区HBsAg阳性率比较有统计学意义差异(χ2=50918,P<0.01),华南地区阳性率最高,华北地区阳性率最低。男女HBsAg阳性率有统计学意义差异(χ2=4951.6,P<0.01)。各年龄段阳性率比较有统计学意义差异(χ2=2118.3,P<0.01),其中<20岁组阳性率最高,为5.23%;≥50岁组阳性率最低,为3.25%。结论加强公共场所的日常管理监测,提高该行业从业人员HepB接种率,重点是男性小年龄组从业人员的HepB接种率,提高全人群防病意识,改变不良的行为习惯,是目前预防乙肝的重要举措。
Objective To understand the prevalence of hepatitis B surface antigen (HBsAg) in Chinese public service establishments and provide the basis for the prevention strategy. Results The positive rates of HBsAg in different years were statistically different (χ2 = 30195, P <0.01), of which the highest in 2002 was 9.57% and the lowest in 2010 was 2.75%. HBsAg positive rate in different industries was statistically significant difference (χ2 = 925.6, P <0.01), the public service industry HBsAg positive rate higher than the food industry. The positive rate of HBsAg in each region was statistically significant difference (χ2 = 50918, P <0.01), the highest positive rate in southern China, the lowest positive rate in northern China. The positive rate of HBsAg between men and women was statistically significant (χ2 = 4951.6, P <0.01). The positive rate of each age group was statistically significant difference (χ2 = 2118.3, P <0.01), <20 years old group was the highest positive rate of 5.23%; ≥ 50-year-old group the lowest positive rate was 3.25%. Conclusion It is important to prevent Hepatitis B (HBV) currently by strengthening the routine management and monitoring of public places and increasing the HepB vaccination rate of practitioners in this industry. The emphasis is on the HepB vaccination rate of practitioners in the younger age group, improving awareness of disease prevention among the whole population and changing bad habits. Move.
