营养素摄入量与高脂血症的关系

目的探索各类营养素摄入量与高胆固醇血症、高甘油三酯血症之间的关系。方法用现况调查结合病例对照研究的方法，随机抽取271名调查对象，按血脂检测结果分为病例组和对照组。用食物模型和流行病学问卷调查表的方法，调查研究对象1年中各种食物摄人量，按食物成分表换算成17类营养素的摄入量，比较病例组和对照组间各类营养素摄入量的差异。结果单因素检验结果显示，病例组每天能量、蛋白质、碳水化合物及粗纤维的摄入量（分别为13193KJ，111．91g，606．31g，10．53g）大于对照组（分别为10904．77KJ，97．23g，427．80g，8．75g），单不饱和脂肪酸的摄入量低于对照组（分别为10．28g和13．97g）。因子分析结果显示，高胆固醇血症病例能量因子得分高于对照组；高甘油三酯血症病例能量因子得分高于对照组，脂肪因子得分低于对照组。结论能量摄入过多是高胆固醇血症和高甘油三酯血症发病的危险因素，不饱和脂肪酸摄入不足是高甘油三酯血症发病的危险因素。

The Relationship between Nutrient Intake and Hyperlipidemia

Objective To identify the relationship between nutrient intake and hyperlipidemia and hyper tfiglyceridemia. Methods 271 samples were randomly selected and divided into case and control groups according to the result of blood detection of lipoprotein.The quantity of nutrients intake in the previous one year was estimated by using the food models, and the matrix calculation, statistic methods were administrated in comparison of the nutrient intake difference between case and control groups. Results The nonparametric test showed that file daily intake of capacity, protein, carbohydrate and pachy - fiber in case group was higher than that of control group and the intake of monounsaturated fatty acid was lower than that of control group. The result of factor analysis showed that the factor score of capacity factor in hypercholesterolemia and hyper triglyceridemia cases was higher than that of control group, and the factor scores of fat factor in hypertriglyceridemia were lower than that of control group. Conclusion Excessive intake of calorie was risk factor of hypereholesterolemia and hyper triglyceridemia, while deficiency of unsaturated fatty acid intake was another risk factor of hyper triglyceridemia.
