Objective: To determine whether the Alternate Healthy Eating Index 2010 (AHEI-2010) provides a more accurate assessment of dietary quality than the Healthy Eating Index 2010 (HEI-2010) in relation to type 2 diabetes (T2DM).
Methods: This study used a representative sample of U.S. adults 20+ years of age (n = 4097) in the 2007-2010 National Health and Nutrition Examination Survey (NHANES). Total HEI-2010 and the AHEI-2010 scores were used to measure dietary quality and were calculated using data from the first 24-hour dietary recall. Health markers evaluated include anthropometrics, blood pressure, lipid and inflammatory markers, and presence of co-morbid diseases. Least Squares Means were computed to determine differences across diabetes status for total and sub-component HEI-2010 and AHEI-2010 scores, and to determine differences across total HEI-2010 and AHEI-2010 quartiles for health markers. Covariate-adjusted logistic regression was used to examine the association between total HEI-2010 and AHEI-2010 scores and diabetes status.
Results: Overall, HEI-2010 (mean total score = 47.3 ± 0.4) and AHEI-2010 (mean total score = 38.2 ± 0.4) both indicate that U.S. adults need improvement in dietary pattern. However, individuals with the highest total HEI-2010 and AHEI-2010 scores in the sample had significantly better health marker values compared to those with the lowest scores (p < 0.01).Diabetics showed higher HEI-2010 and AHEI-2010 scores compared to prediabetics and nondiabetics but did not have better health markers. There were significant differences in some of the sub-component HEI-2010 and AHEI-2010 scores across T2DM status (p < 0.01). For HEI-2010 component scores, diabetics had highest scores for total protein foods and empty calories. For AHEI-2010 component scores, diabetics had the highest scores for sugar-sweetened beverages and fruit juice, sodium, and lowest scores for alcohol and red and/or processed meats. However, results suggest that neither total HEI-2010 nor AHEI-2010 scores were significant predictors of T2DM (p> 0.05).
Conclusion: Neither total HEI-2010 nor AHEI-2010 scores performed better in terms of their relationship with diabetes status. The HEI-2010 and AHEI-2010 were not developed specifically for use in assessing dietary quality in diabetics. Future research is needed to improve the assessment of dietary quality among individuals with T2DM.
