[目的]研究探讨共用剃刀等危险因素与乙型肝炎传播的关系。[方法]对282名单纯HBsAg检测为阳性的献血者及564名阴性献血者进行病例对照研究,应用多因素条件Logistic回归模型分析与感染丙肝有关的因素,并对危险因素的人群归因危险度(PAR)进行估计。[结果]筛选出8个与感染乙肝有关的因素,使用共用剃刀、手术史、针灸史、10年前注射史、乙肝家族史、纹身、牙科史、穿耳环孔等因素增加感染的危险性,其危险度(OR)分别是:10.1235、2.5892、8.5870、8.4407、3.4377、5.5253、2.3673、3.1369,人群归因危险度分别是:49.22%,13.93%,17.23%,77.21%,16.60%,10.16%,26.21%,20.77%。8项危险因素总的人群归因危险度为96.81%。[结论]共用剃刀以及可能导致血液接触的器具是乙型肝炎传播的危险因素。
[Objective] To study the relationship between risk factors such as sharing razor and hepatitis B transmission. [Methods] A total of 282 blood donors who were tested positive for HBsAg and 564 negative donors were enrolled in the case-control study. Multivariate conditional logistic regression model was used to analyze the factors associated with hepatitis C infection. The risk attribution risk (PAR) estimate. [Results] Eight factors related to hepatitis B infection were screened, and the risk of infection was increased by using the common razor, operation history, acupuncture history, injection history 10 years ago, family history of hepatitis B, tattoo, dental history, The risk (OR) was 10.1235,2.5892,8.5870,8.4407,3.4377,5.5253,2.3673,3.1369 respectively. The risk attributable to the population was 49.22%, 13.93%, 17.23%, 77.21%, 16.60% and 10.16%, respectively. , 26.21%, 20.77%. The risk of attribution to the eight risk factors was 96.81%. [Conclusion] Common razors and instruments that may cause blood contact are risk factors of hepatitis B transmission.
