The aim of this study was to investigate the ability of diet quality indices in predicting obesity and abdominal obesity in a population in nutrition transition.
This study explored the association of the Mediterranean Diet Scale (MDS), Healthy Eating Index-2005 (HEI-2005), and Diet Quality Index-International (DQI-I) with body mass index (BMI) and waist circumference (WC) in a cross-sectional study after 6.7 years of follow-up in the Tehran Lipid and Glucose Study (TLGS) population.
Out of 192 subjects who had BMI < 25kg/m(2) and of 283 subjects who were free of abdominal obesity at baseline, 39.6% developed overweight and obesity and 43.1% developed abdominal obesity, respectively during 6.7 years of follow-up in the study population. In cross-sectional analysis, after adjusting for age, sex, energy intake, physical activity and smoking status, multivariate analysis of covariance did not show any significant results regarding the relation of the diet quality indices, BMI and WC. According to follow-up analysis, none of the indices had significant associations with BMI and WC after adjustments for confounders and baseline values of BMI and WC.
Adherence to MDS, HEI-2005, and DQI-I could not predict BMI and WC in Iranian participants after 6.7 years of follow-up.
本研究旨在探讨膳食质量指数在营养转型人群中预测肥胖和腹型肥胖的能力。
本研究在经过 6.7 年随访的德黑兰血脂和血糖研究（TLGS）人群中，探讨了地中海饮食量表（MDS）、健康饮食指数-2005（HEI-2005）和饮食质量指数-国际（DQI-I）与体重指数（BMI）和腰围（WC）的相关性。
在基线时 BMI<25kg/m²的 192 名受试者和无腹型肥胖的 283 名受试者中，分别有 39.6%和 43.1%在研究人群中随访 6.7 年后发展为超重和肥胖以及腹型肥胖。在横断面分析中，调整年龄、性别、能量摄入、体力活动和吸烟状况后，多变量协方差分析显示膳食质量指数与 BMI 和 WC 之间没有显著关系。根据随访分析，在调整混杂因素和 BMI 和 WC 的基线值后，这些指数与 BMI 和 WC 均无显著相关性。
在经过 6.7 年的随访后，MDS、HEI-2005 和 DQI-I 的依从性并不能预测伊朗参与者的 BMI 和 WC。
