老年人脂肪肝与冠心病危险因素的相关性

Correlation between non-alcoholic fatty liver and coronary risk factors in elderly men

目的探讨老年人脂肪肝与冠心病危险因素之间的关系。方法调查920例老年男性,分析其脂肪肝与年龄、体质指数(BMI)、平均血压、谷丙转氨酶、总胆固醇、甘油三酯、空腹血糖、吸烟和饮酒之间的关系,并对脂肪肝、肥胖与高血压、高胆固醇血症、高甘油三酯血症、糖尿病之间的关系进行多元回归分析。结果920例老年男性非肥胖(BMI<28kg/m2)与肥胖(BMI≥28kg/m2)者脂肪肝的患病率(分别为111%和409%)比较,差异有显著性(P<005)。脂肪肝的患病率与高甘油三酯血症呈显著正相关(OR=3491,P<001),与高胆固醇血症、糖尿病呈正相关(OR=1539、1585,均为P<005)。当将肥胖和脂肪肝分别与冠心病的危险因素进行相关分析,在脂肪肝组中冠心病危险因素除高血压外OR值均高于肥胖组。结论在男性老年人群中,脂肪肝与冠心病的危险因素有相关性。

Objective To determine the association between fatty liver and coronary risk fcators in elderly men. Methods A cross-sectional study of 920 elderly men with or without fatty liver and obesity was performed in 2002. Age, body mass index (BMI), GPT, cholesterol, triglyceridemia, fast glucose, mean blood pressure, smoking and drinking consumption were analyzed. Results The prevalence of fatty liver was 11.1% in the non-obese participants (BMI<28 kg/ m^2 ) and 40.9% in the obese participants (BMI≥28 kg/m^2 ) (P<0.05). In elderly men, fatty liver was significantly (OR=3.491,P<0.01) related to hypertriglyceridemia, hypercholesterolemia and diabetes mellitus glucose (DM). Fatty liver had higher odds ratio for hypercholesterolemia, hypertriglyceridemia and DM than obesity except hypertention(OR=1.539, 1.585,all P<0.05). Conclusions Fatty liver is associated with coronary risk factors in elderly men.
