目的:探讨肥胖与冠心病的相关性。方法:随机整样选取体检人员中175例男性冠心病患者(冠心病组)及175例健康男性(对照组),应用生理电阻抗分析法(bioelectrical impedance analysis,BIA)进行人体成分测定,并对测定结果进行统计分析。结果:(1)冠心病组与对照组的人体成份组成比较,体脂肪(BF)、体脂百分数(BF%)、腰臀脂肪比(WHR)在冠心病组明显升高(P<0.05),下肢非脂肪物质(LBM)明显下降(P<0.05);(2)以BF%作为标准,冠心病组的肥胖率明显高于对照组(P<0.01);(3)多因素逐步回归分析显示,冠心病与BF%、WHR、下肢LBM具有显著的回归效果,且WHR的偏回归系数最大。结论:肥胖是冠心病的危险因素之一,在冠心病的发病中起着重要作用。冠心病与肥胖,特别是中央型肥胖关系密切。
Objective: To investigate the correlation between obesity and coronary heart disease. Methods: One hundred and seventy-five subjects with CHD (coronary heart disease) and 175 healthy men (control group) were enrolled in the random sample. The body composition was measured by bioelectrical impedance analysis (BIA) Measurement results for statistical analysis. Results: (1) Compared with the control group, body fat composition (BF), body fat percentage (BF%) and waist hip fat ratio (WHR) were significantly increased in CHD group (P <0.05); (2) Obesity rate in coronary heart disease group was significantly higher than that in control group (P <0.01) with BF% as the standard; (3) Multi-factor stepwise regression analysis Show, coronary heart disease and BF%, WHR, lower limb LBM has a significant regression effect, and WHR partial regression coefficient maximum. Conclusion: Obesity is one of the risk factors of coronary heart disease and plays an important role in the pathogenesis of coronary heart disease. Coronary heart disease and obesity, especially central obesity are closely related.
