目的了解我国城市餐饮从业人员HBV-M常见模式构成,为制定防制策略提供依据。方法HBsAg初筛阳性者采用酶联免疫吸附方法检测HBV-M,应用文献系统综述方法分析模式构成。结果2000～2007年11城市体检722 909人,HBsAg阳性率为6.00%。阳性率最高为沿海地区,其次为南方城市和北方城市,城市间差异极显著。HBsAg阳性率分布南方多于北方,东部多于西部。抗-HBs阳性率明显低于全国调查水平,最高为北方城市,其次为南方城市和沿海地区,地区间比较均有显著差异。HBV-M不同地区间差异显著(P≤0.001)。差异最大的为沿海城市,其次为南方城市和北方城市。结论首次揭示城市餐饮从业人员HBsAg阳性率为6.00%和感染模式构成,提示应强化乙肝疫苗接种,对控制传播、制定防制策略有重要意义。
Objective To understand the composition of common patterns of HBV-M in urban catering industry in our country and provide evidence for the development of control strategies. Methods HBV-M was detected by enzyme-linked immunosorbent assay (ELISA) in primary screening HBsAg positive patients. Results From 2000 to 2007, the city’s physical examination was 722,909 and the positive rate of HBsAg was 6.00%. The highest positive rate was in coastal areas, followed by southern cities and northern cities, with significant differences among cities. HBsAg positive rate distribution more than the north south, east than the west. The positive rate of anti-HBs was significantly lower than the national survey level, the highest for the northern cities, followed by the southern cities and coastal areas, between the regions were significantly different. HBV-M significant differences between different regions (P≤0.001). The biggest differences are coastal cities, followed by southern cities and northern cities. Conclusion It is the first time to reveal that the positive rate of HBsAg in urban catering workers is 6.00% and the mode of infection constitutes, suggesting that hepatitis B vaccination should be intensified, which is of great significance for controlling transmission and making prevention and control strategies.
