During 1986-1987, 480 employees of the Tel-Aviv Medical Center were screened for hepatitis B virus (HBV) markers as a preliminary step in a vaccination campaign. One hundred and seventeen (24.4%) had evidence of previous infection, including nine (1.9%) carriers. The effect of potential risk factors on seropositivity was evaluated by multiple logistic regression analysis, which enabled assessment of the individual contribution of each risk factor under the specific environmental conditions. The following risk factors were found to influence seropositivity: origin from Third World countries as opposed to the Western World, employment as sanitary workers, age over 40 years, and history of accidental needle punctures. In the heterogeneous Israeli population, hospital workers had a relatively high prevalence of HBV markers, probably resulting from occupational exposure.
1986年至1987年期间，作为疫苗接种运动的初步步骤，对特拉维夫医疗中心的480名员工进行了乙肝病毒（HBV）标志物筛查。117人（24.4%）有既往感染证据，其中9人（1.9%）为携带者。通过多因素逻辑回归分析评估潜在风险因素对血清学阳性的影响，该分析能够评估在特定环境条件下每个风险因素的个体贡献。发现以下风险因素会影响血清学阳性：来自第三世界国家而非西方世界、从事卫生工作、年龄超过40岁以及有意外针刺史。在异质性的以色列人群中，医院工作人员的HBV标志物患病率相对较高，可能是由于职业暴露所致。
