为了探索病毒性肝炎多重感染的危险因素 ,对 6 3例病毒性肝炎多重感染的患者以 1∶1配对进行病例对照研究 ,危险因素的确立采用单因素配对 χ2 分析和多因素条件回归分析方法。结果 :单因素分析显示家庭成员既往肝炎史 (OR =6 )、输血及血制品应用史 (OR =38)、肝炎接触史 (OR =6 ) 3个因素与病毒性肝炎多重感染有关。多因素分析显示肝炎接触史有统计学显著性意义 (OR =13 0 )。结论 :肝炎接触史是本地区病毒性肝炎多重感染的主要危险因素
In order to explore the risk factors of multiple viral hepatitis infection, a case-control study was conducted on 63 patients with multiple viral hepatitis infection by 1: 1 pairing. The risk factors were established by one-way pairedχ 2 analysis and multivariate conditional regression analysis. Results: Univariate analysis showed that family members had previous history of hepatitis (OR = 6), history of blood transfusion and application of blood products (OR = 38), history of hepatitis exposure (OR = 6) and viral hepatitis multiple infection. Multivariate analysis showed that the history of hepatitis exposure was statistically significant (OR = 130). Conclusions: Hepatitis exposure history is a major risk factor for multiple viral infections in this region
