156例健康人群多烯不饱和脂肪酸水平与血脂的关系

The relationship between the levels of polyunsaturated fatty acid and the blood lipid in 156 healthy persons

目的了解我国多烯不饱和脂肪酸(PUFA)的水平状况,并进一步了解PUFA与血脂的相关性。方法健康人群体检156例血标本,采用国际通用的方法进行PUFA检测,同时对体重指数、血脂水平等进行检测。结果ω-3PUFA水平偏低,但ω-6PUFA/ω-3PUFA比值在属合理范围,ω-3PUFA与三酰甘油呈负相关,与高密度脂蛋白胆固醇(HDL-C)呈正相关。二十碳五烯脂肪酸和二十二碳六烯脂肪酸分别与三酰甘油呈负相关,与HDL-C呈正相关。结论ω-3PUFA可调节血脂,降低三酰甘油的水平,对人体健康具有重要作用。

Objective To study the level of polyunsaturated fatty acid（PUFA）,and its correlation with lipid and other factors in blood.Methods the level of PUFA and blood lipid was detected in 156 healthy persons,the blood samples were tested by combined thin-layer and gas liquid chromatographic analysis.Results The level of ω-3PUFA fatty acid was lower in this group,the ratio ω-6 PUFA/ω-3PUFA was within reasonable zone.There were strong inverse correlations between the ω-3 PUFA and the triglyceride,and strong positive correlation between the ω-3 PUFA and HDL.EPA and DHA were inversely correlated with triglyceride,and positively correlated with HDL.Conclusions The ω-3 PUFA can modify the levels of blood lipid,and lowers down the triglyceride,thus may benefit human health.
