强化复合膳食纤维饮食对单纯性肥胖者体重和血脂的影响

目的探讨强化复合膳食纤维饮食对单纯性肥胖者体重和血脂的影响。方法将68例单纯性肥胖者随机分为强化膳食纤维组(34例)和对照组(34例),两组从基线期开始给予相同模式的饮食,强化膳食纤维组每日额外给予16g复合膳食纤维制剂随餐服用,而对照组给予16g外观和性状相似的小麦粉,8周后观察两组患者体重和血脂的变化情况。结果 8周后,强化膳食纤维组的体重、体重指数、腰围、总胆固醇和低密度脂蛋白胆固醇的水平均较基线期和对照组明显降低(P0.05),高密度脂蛋白胆固醇和甘油三酯的水平差异无统计学意义(P0.05);而在对照组中,各项观察指标前后比较差异均无统计学意义(P0.05)。结论强化复合膳食纤维饮食可降低单纯性肥胖者的体重、总胆固醇和低密度脂蛋白胆固醇。

Effect of Enhanced Diet with Compound Dietary Fiber on Body Weight and Blood Lipid Level of Simple Obese Patients

Objective To investigate the effect of enhanced diet with compound dietary fiber on body weight and blood lipid level of simple obese patients. Methods 68 simple obesity patients were randomly divided into dietary fiber - fortified group （ n = 34） and the control group （n = 34）. The dietary fiberfortified group was given 16g compound dietary fiber supplement with meals daily, and the control group was given 16g wheat flour whose appearance was similar to compound dietary fiber supplement. The changes of body weight and lipid level of the subjects in each group were measured 8 weeks later. Results Compared with the baseline data and the control group, the dietary fiber-fortified group had significantly decreased body weight, body mass index, waist circumference, total cholesterol and lowdensity lipoprotein cholesterol （ P〈 0. 05）, but there was no significant change in high -density lipoprotein cholesterol and triglyceride （ P〉 0.05）. All the variables in the control group had no significant change before and after the intervention （P 〉 0. 05 ）. Conclusion Enhanced diet with compound dietary fiber may decrease the body weight, total cholesterol and low - density lipoprotein cholesterol in simple obesity patients.
