冠心病病人的饮食行为与血脂和脂质过氧化关系的研究

Relationship between unhealthy dietary behavior and blood lipids and lipid peroxides in coronary heart disease patients

用病例－对照研究方法，以９７对（１１）冠心病患者和健康人作为研究对象。分别进行体格测量、膳食史及饮食行为调查，并测定血清总胆固醇（ＴＣ）、甘油三脂（ＴＧ）、高密度脂蛋白胆固醇（ＨＤＬ－Ｃ）、低密度脂蛋白胆固醇（ＬＤＬ－Ｃ）和脂质过氧化物（ＬＰＯ）。结果表明，冠心病患者ＴＣ，ＴＧ，ＬＤＬ－Ｃ和ＬＰＯ的水平都明显高于对照组，冠心病组的不良饮食行为也明显多于对照组（χ２＝５５．８１，Ｐ＜０．０１），表明不良饮食行为是引起血脂增高和脂质过氧化物增多的重要因素。而且不良饮食行为较多的人群发生冠心病的危险度增大（ＯＲ＝３．８８）。

The effects of unhealthy dietary behavior on blood lipids(TC,TG,HDL C,LDL C)and lipid peroxides(LPO) and the occurrence of coronary heart disease(CHD) were measured in 97 CHD patients and 97 controls without any clinical appearance of cardiovascular or cerebrovascular diseases.The results showed that the serum level of TC,TG,HDL C,LDL C and LPO were significantly higher in CHD group than control group.More unhealthy dietary behavior was observed in CHD group than in control group.The odds ratio of the population with more than 3 items of unhealthy dietary behavior was 3 88.The results of this study suggested that unhealthy dietary behavior might play an important role in increasing the risk of CHD.
