目的研究献血者感染乙肝病毒(HBV)的相关危险因素。方法对203名单纯HBsAg阳性的献血者及406名所有血液检测项目均阴性的献血者进行对照研究,应用多因素条件Logistic回归模型分析与HBV感染有关的因素,并对危险因素的人群归因危险度(PAR)进行估计。结果筛选出5项与感染HBV有关的因素,研究发现使用共用剃刀、乙肝家族史、内窥镜检查史、牙科治疗史、未注射乙肝疫苗可以增加乙肝感染的危险性,其危险度(OR)分别是:4.010 2、2.808 2、5.815 7、1.758 3、4.044 4,人群归因危险度分别是:43.39%,5.50%,1.75%,13.46%,29.91%。5项危险因素总的人群归因危险度为66.78%。结论使用共用剃刀、乙肝家族史、内窥镜检查史、牙科治疗史、未注射乙肝疫苗是HBV感染的危险因素。
Objective To study the related risk factors of hepatitis B virus (HBV) infection in blood donors. Methods A total of 203 blood donors with HBsAg positive and 406 blood donors with negative blood tests were compared. Multivariate conditional logistic regression analysis was used to analyze the factors associated with HBV infection, and the risk of at-risk population Degree (PAR) is estimated. Results Five factors related to HBV infection were screened out. The study found that the risk of hepatitis B infection could be increased by using the common razor, family history of hepatitis B, history of endoscopy, history of dental treatment and non-injection of hepatitis B vaccine. The risk (OR) Respectively: 4.010 2,2.808 2,5.815 7,1.758 3,4.044 4, the risk attributable to the population are: 43.39%, 5.50%, 1.75%, 13.46%, 29.91%. The total risk of five risk factors attributable to the risk of 66.78%. Conclusion The common razor, family history of hepatitis B, history of endoscopy, history of dental treatment and non-injection of hepatitis B vaccine are risk factors for HBV infection.
