Resumen:
Objectives: The aim of this study was to evaluate the independent association of the dietary inflammatory index (DII (R)) score with overweight and obesity in Brazilian participants of the Cohort of Universities of Minas Gerais (CUME project). Methods: This was a cross-sectional study consisting of 3,151 graduates and postgraduates (2197 women) with a mean (SD) age of 36.3 y (+/- 9.4 y). Sociodemographic characteristics, lifestyle, and anthropometric data were assessed via online self-reported questionnaire. Additionally, a validated food frequency questionnaire with 144 food items was used to generate energy-adjusted DII (E-DII (TM)) scores, which evaluated the inflammatory potential of the diet. Results: The prevalence of overweight and obesity were 28.2% and 11%, respectively. Participants in the highest E-DII quartile (most proinflammatory diet) were more likely to be smokers former smokers; sedentary; and consumers of red and ultra-processed meats, fats and oils (excluding olive oil), bottled fruit juices and soft drinks, sugars, sweets, and higher overall caloric intake, compared with the first quartile of E-DII. Both men and women in the fourth E-DII quartile had the highest prevalence of overweight and obesity (prevalence ratio [PR], 1.35; 95% confidence interval [CI], 1.14-1.59 and PR, 1.97; 95% CI, 1.20-3.22, respectively, in men; PR, 1.38; 95% CI, 1.17 to 1.65 and PR, 1.95; 95% CI, 1.31-2.90, respectively, in women). Conclusion: The most proinflammatory dietary pattern was associated with a higher prevalence of overweight and obesity and other unhealthy lifestyles including being sedentary, smoking, and consuming a obesogenic diet.
