为了解本地区戊型肝炎（ＨＥ）流行特征及危险因素，于１９９４年３～１２月对３８５例急性散发性病毒性肝炎进行血清学分型。结果：甲型肝炎１９１例（４９．６１％），乙型肝炎１０４例（２７．０１％），丙型肝炎２０例（５．１９％），ＨＥ３４例（８．８０％），未能分型２２例（５．７２％）。ＨＥ男∶女为６．５∶１，发病平均年龄３８．５岁；临床特点：起病急，病程短，预后好；３例ＨＥ孕妇中，１例发生死胎。将１９９３～１９９４年确诊的７０例ＨＥ病人作病例组，按性别年龄配比选７０例非肝炎病人作对照，进行配比病例对照研究，经单因素和多因素条件ｌｏｇｉｓｔｉｃ回归分析表明：在外用餐史（ＯＲ２．０１，９５％ＣＬ１．２８～３．１５），肝炎接触史（ＯＲ６．０４，９５％ＣＬ１．２４～２９．２９），不洁饮食史（ＯＲ２．１６，９５％ＣＬ２．０５～２．２６），３个因素为本病的主要危险因素。
To understand the epidemiological characteristics and risk factors of hepatitis E (HE) in the region, 385 cases of acute sporadic viral hepatitis were serotyped from March to December 1994. Results: 191 cases of hepatitis A (49.61%), 104 cases of hepatitis B (27.01%), 20 cases of hepatitis C (5.19%) and 34 cases of HE (8.80% Type 22 cases (5.72%). HE male: female 6.5: 1, the average age of onset of 38.5 years old; clinical features: acute onset, short course, good prognosis; 3 cases of HE pregnant women, 1 case of stillbirth. 70 cases of HE patients diagnosed from 1993 to 1994 were selected as the case group and 70 cases of non-hepatitis patients were selected as the control by sex age-matched to carry out comparative case-control study. The single-factor and multi-factor conditional logistic regression analysis showed that: (OR2.01,95% CL1.28 ~ 3.15), hepatitis history (OR6.04,95% CL1.24-29.29), unclean diet history (OR2.16,95% CL2.05 ~ 2.26), three factors are the main risk factors for this disease.
