西安市急性病毒性庚型肝炎危险因素的病例对照研究

A CASE-CONTROL STUDY ON THE ETIOLOGICAL FACTORS OF HGV

为了探讨庚型肝炎的危险因素，调查了西安市五家医院的急性散发性病毒性庚型肝炎患者１７例以及按年龄、性别等齐同原则配比的医院对照６８例，进行１∶４配比病例对照研究。结果发现：无论是单因素分析还是多因素条件Ｌｏｇｉｓｔｉｃ回归分析，输血史、住院史都是庚型肝炎重要的危险因素。手术史也可能与庚型肝炎感染有关，而肝炎接触史、不洁饮食史、注射史、针灸史等因素则未发现与庚型肝炎的传播有关。

To investigate the etiological factors of Hepatitis G, a case-control study including 17 cases and 68 controls which were 1∶4 matched on sex,age, occupation and educational degree was carried out.The results from single factor analysis and multi-factorial conditional logistic regression analysis both showed that factors as transfusion of blood,history of hospitalization were the risk factors for HGV infection. The history of surgical operation also might be related to HGV infection.But contact with hepatitis patient,injection or eating unclean foods were not found to have relations with HGV infection.
