Abstract: BACKGROUND: The aim of this study was to examine the association between dietary quality measured by inflammatory potential of a diet and Alternative Healthy Eating Index-2010 (AHEI-2010), and obesity-related metabolic risks in a representative sample of Iranian obese adults. METHOD: This cross-sectional study was conducted on 300 obese adults. Dietary intake was assessed using a validated 168-item semi-quantitative food frequency questionnaire (FFQ). Diet quality was measured using AHEI-2010 and Empirical Dietary Inflammatory Pattern (EDIP) scores. RESULTS: Those in the upper quartile of AHEI-2010 were associated with lower serum level of triglycerides (TG), and higher body mass index (BMI), compared to participants in the lower quartile. Those in the higher quartile of EDIP score were associated with higher serum level of TG. Greater adherence to AHEI-2010 had 70% lower odds of high fasting blood glucose (FBG), compared with those in the first quartile [Q4 vs Q1: OR, 0.3 (95% CI: 0.1–0.8), p trend = 0.02] Those in the highest quartile of EDIP score had a 60% higher odds of high diastolic blood pressure, compared with those in the lowest quartile [Q4 vs Q1: OR, 2.4 (95% CI: 1.1–5.5), p trend = 0.05] after controlling for potential covariates. CONCLUSIONS: High diet quality incorporating more anti-inflammatory diet may have a potential benefit in reducing obesity-related metabolic risks.
