体质指数与冠心病血脂关系的对照研究

A control study on the relationship between body mass index and coronary heart disease or its blood lipids level

目的:探讨冠心病患者的体质指数(BMI)与血脂异常的关系。方法:采用病例对照研究方法,以83对(1: 1)冠心病患者和健康人为对象,测量身高、体重,并计算BMI;测定血清总胆固醇(TC)、甘油三酯(TG)、低密 度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)含量。结果:冠心病组BMI平均值明显大于对照组(t =2．36,P<0．05),冠心病组超重和肥胖的检出率明显高于对照组(74．39％:34．94％,x2=24．85,P<0．01);超 重和肥胖与冠心病密切相关(OR=2．63)。冠心病组血脂异常的检出率也明显高于对照组(x2=24．85,P<0．01);冠 心病与正常对照组合并计算BMI与TC、TG、LDL-C呈正相关(r=0.688、0.406、0.243,P<0.01、0.01、0.05)。 结论:BMI与冠心病高血脂症密切相关。

Objective： To explore the relationship between body mass index （BMI） and coronary heart disease （CHD） or its blood lipids level, Methods： The height, weight and serum level of TC, TG, LDL-C, HDL-C were measured in 83 CHD patients and 83 controls without any clinical appearance of cardiovascular or cerebrovascular diseases. Results ： The detectable rate of overweight or obesity was significantly higher in CHD group than that in control group. Overweight or obesity correlated positively with CHD （OR=2. 63）. The detectable rate of lipids disorder was significantly higher in CHD group than that in control group, and its lipids disorder increased with BMI. BMI correlated positively with TC, TG, LDL-C （r=0. 688, 0. 406, 0. 243）. Conclusion： BMI correlated positively with CHD or its levels of TC, TG, LDL-C.
