低血糖指数膳食对代谢综合征患者体重指数、腰臀比值及内脏脂肪的影响

目的研究低血糖指数（GI）膳食对代谢综合征（MS）患者体重指数（BMI）、腰臀围比值（W/H）和内脏脂肪的影响。方法选取BMI≥25 kg/m2的MS患者296例,进行为期8周的低GI膳食的标准化的营养干预,观察干预前后BMI、W/H、VFA及非酒精性脂肪肝（NAFLD）的变化情况,采用SPSS 15.0软件包进行统计分析。结果干预后BMI、W/H下降,VFA减少,NAFLD的严重程度改善,与干预前对比,P均〈0.01,有统计学意义。结论在控制总能量的基础上,采用低GI膳食的标准化营养干预能有效改善MS患者的BMI、W/H、内脏脂肪积聚及NAFLD。

Effect of low glycemic index diet on body mass index, waist/hip ratio and visceral fat in metabolic syndrome patients

Objective To study the effect of low glycemic index diets on body mass index （BMI）, waist/hip ratio （W/H） and visceral fat in the metabolic syndrome （MS） patients. Methods 296 MS patients whose BMI≥ 25 kg/m^2 were selected to carry out the nutrition intervention with a low glycemic index diet for eight weeks. The alterations of BMI, W/H, visceral fat area （VFA） and nonalcoholic fatty liver disease （NAFLD） were observed, and the data was statistically analyzed using SPSS15.0 package. Results BMI,W/H and VFA were decreased, and fatty liver was improved significantly after intervention with the low glycemic index diet （P〈0. 01）. Conclusion Low glycemic index diets based on controlling total energy have effects on the improvement of BMI,W/H,visceral fat and NAFLD in MS patients.
