Diet Quality Indices and Their Correlation with Glycemic Status and Lipid Profile in Patients with Type 2 Diabetes

BACKGROUND: The study aimed to determine the correlation between different diet quality indices and glycemic status and lipid profile in patients with diabetes. METHODS: This study was carried out on 235 patients with type 2 diabetes referred to Martyr Motahari Diabetes Clinic of Shiraz city so as to investigate the relationship between glycemic status and lipid profile and the diet quality using Healthy Eating Index (HEI-2010), phytochemical index (PI), and Diet Quality Index-International (DQI_I). RESULTS: A positive correlation was indicated between the serum levels of LDL-C and HEI-2010 scores (p=0.026). Furthermore, there was a positive correlation between the patients' age and scores of PI (p=0.006) and between PI and DQI_I (p < 0.001). There was no significant relationship between the scores for all three indicators and biochemical parameters. CONCLUSION: The results of this study indicated that there was a significant correlation between the serum LDL-C levels and the HEI-2010 scores. Moreover, the age of the patients had a direct correlation with the PI scores.
