The Study of Relationship Between Drinking and Fatty Liver In Railway Workers

[目的]研究铁路职工饮酒习惯与脂肪肝患病率的关系。[方法]采用病例对照研究方法,对共调查304例经B超诊断的脂肪肝患者及540人对照组,用SAS（6.12）软件对资料进行χ^2检验。[结果]饮啤酒和白酒者患脂肪肝的相对危险度较很少饮酒者分别增加1.092倍和2.098倍,饮酒34次/周和每天饮酒者患脂肪肝的相对危险度较很少饮酒者分别增加1.329倍和3.329倍,饮酒等级（g/日×年）〉600者患脂肪肝的相对危险度较〈600者增加了57.4%。[结论]饮酒习惯与脂肪肝的发生率有显著相关性。
