Association between adherence to MIND diet and general and abdominal obesity: a cross-sectional study

Abstract

Background: Recently, a new eating pattern called as "Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND)" has been coined. Emerging studies are examining this dietary pattern with chronic conditions. We aimed to investigate the association between the MIND diet score and general and central obesity among adults. Methods: This cross-sectional study was conducted in a framework of the Study on the Epidemiology of Psychological Alimentary Health and Nutrition (SEPAHAN). Dietary information was collected using a validated self-administered 106item Willett-format dish-based semi-quantitative food frequency questionnaire (DS-FFQ) in 6724 adults. Adherence to the MIND diet was examined based on components suggested in this eating pattern. Anthropometrics data were collected using a validated self-reported questionnaire. General obesity was defined as body mass index ≥30 kg/m 2 , and abdominal obesity as waist circumference > 102 cm for men and > 88 cm for women. Results: Mean age, BMI and WC in the study population was 36.8 ± 8.08 y, 24.9 ± 3.8 kg/m 2 and 83.7 ± 16.02 cm, respectively. Overall, 9.5% of subjects were generally obese and 24.4 were abdominally obese. Examining the whole study population, we found no significant association between the MIND diet score and odds of general obesity, either before (ORs for comparing T3 vs. T1: 1.03; 95% CI: 0.83, 1.27; P-trend = 0.74) or after controlling for potential confounders (ORs for T3 vs. T1: 0.91; 95% CI: 0.67, 1.25; P-trend = 0.58). This was also the case for men and women when analyzed separately. We also failed to find any significant association between the MIND diet score and odds of abdominal obesity after controlling for potential confounders in the whole study population (ORs for T3 vs. T1: 1.00, 95% CI: 0.79, 1.27; P-trend = 0.87). However, women with the greatest adherence to the MIND diet were 19% less likely to be abdominally obese than those with the lowest adherence in crude model (OR = 0.81; 95% CIs: 0.67, 0.98; P-trend = 0.03). This association disappeared after controlling for potential confounders (OR = 0.87; 95% CIs: 0.66, 1.14; P-trend = 0.55). Conclusion: No significant association was observed between adherence to the MIND diet and odds of general and central obesity.

Associations between adherence to MIND diet and metabolic syndrome and general and abdominal obesity: a cross-sectional study

“…Another meta-analysis showed that adherence to the DASH diet significantly decreases body weight (about-1.42 kg in 8-24 weeks), BMI, and WC, especially along with energy-restricted diets [26]. In contrast, Aminianfar et al [27] found no significant association between adherence to the MIND diet and odds of general and central obesity in both men and women. However, they did not include olive oil in the score and their sample size was lower.…”

“…There are limited studies on the relationship between the MIND diet and obesity. Aminianfar et al [14] found no significant association between adherence to the MIND diet and general and central obesity in a sample of Iranian adults live in Isfahan. However, the relationship between the MIND diet and MetS has not been assessed.…”

“…Moreover, in brainunhealthy food groups, we advocated scores of 1, 0.5, and 0 to individuals of the lowest, middle, and the highest tertiles, in order. Finally, the total MIND diet score was obtained by summing up the scores of these food items and ranged from 0 to 13 [19].…”

Adherence to the MIND diet and the risk of cardiovascular disease in adults: a cohort study

“…The MIND diet and CVD risk factors have been studied in a few studies. 20,21 The Framingham Offspring Cohort, on 2512 participants, indicated a significant positive association between the MIND diet and left ventricular mass (LVM) in females. On the contrary, an inverse association between the MIND diet and global circumferential strain (GCS) among subjects, aged >66 years was reported.…”

“…19 The relationship between the MIND diet and CVD risk factors was investigated in two cross-sectional studies, but no indication of a link was found. 20,21 However, it has yet to be determined whether the MIND diet is associated with the lower incidence of CVD.…”
