摘　　要：目的了解西安地区饮食和公共场所从业人员HBsAg阳性率、HBsAg动态变化与乙型肝炎(乙肝)报告发病率动态的相关性。方法采用1994—2003年饮食、公共场所从业人员健康体检HBsAg检验结果和周期疫情报告数据,进行统计分析。结果1994—2003年,共进行体检342630人,HBsAg总阳性率为3.79%。10年间HBsAg阳性率波动在2.94%～4.28%间(χ2=34.38,P<0·01),各月份HBsAg阳性率比较,χ2=34.26,P<0·01;各季度HBsAg阳性率比较,χ2=68.58,P<0·01,差异均有统计学意义。HBsAg阳性检出率与乙肝报告发病率,经相关性分析,相关系数rs以季度最高(rs=0.8000),其次为年度(rs=0.7409)和月份(rs=0.1503)。结论HBsAg阳性率和报告发病率动态变化有较明显的相关性,可能通过对HBsAg阳性率的分析,较好地判定报告发病率动态变化。[ Objective] To learn the dynamic correlation between the positive rate of HBsAg and the reported morbidity of hepatitis B among the working staff in catering industry and public places. [ Methods] The result of the HBsAg detection and the periodical epidemic report of the catering industry and public places during 1994 -2003 were statistically analyzed. [ Results] A total of 342630 persons were examined during 1994 - 2003, the total positive rate was 3.79% ; the positive rate of HBsAg during the ten years fluctuated between 2.94% and 4.28% （ P 〈 0. 011 ; significant difference was found between different months and quarters （ P 〈 0.01 ; P 〈 0. 1 ） ; the correlative analysis of the positive rate of HBsAg and hepatitis B report morbidity indicted that the correlative coefficient rs was the highest in seasons （ rs = 0. 8000 ）, then annual （ rs = 0. 7409 ） and months （ rs = 0. 1503 ）. [ Conclusion] The positive rate of HBsAg is proved to have obvious correlation with the reported morbidity changes; the dynamic changes of the morbidity can be finely estimated through analyzing the positive rate of HBsAg.
