Data from the MIND diet trial showed meaningful weight loss and cognitive improvement over 3 years. This analysis tests whether the MIND diet’s cognitive effects vary by baseline BMI. Using a linear mixed-effect model and annual change in global cognition from 12 neurocognitive tests, participants (N=604) average 70.4 years old.

In the current study, we examined whether the effect of the MIND diet intervention on cognition differs across people with different body mass index (BMI) at enrollment. The MIND trial enrolled older adults without cognitive impairment but with a family history of dementia, BMI>25, and a suboptimal diet. A linear mixed-effect model was used to examine if BMI modified the effect of MIND on cognition, specifically annual change in a global cognition score derived from a battery of 12 neurocognitive tests. Participants (N = 604) were, on average, 70.4 years old, 65.5% female, and with a BMI of 33.9 kg/m2 at baseline. In a multivariable-adjusted model, there was a significant interaction between intervention x BMI x time (p= .011); as such, among individuals with BMI>35 kg/m2 (n = 213), those within the MIND diet group showed a slower rate of decline in global cognition by 0.040 (SE = 0.017, p=.018) standardized units per year when compared to people in the control diet group. In people with BMI\u003C 35, there were no differences between the MIND diet and the control group in global cognition. Future work should examine underlying mechanisms that explain the cognitive benefits of the MIND diet among people with obesity.","cbCaiiWlusZKNynB","https://ap.wps.com/l/cbCaiiWlusZKNynB","pdf",1134474,"English","# Intervention and rationale\n## Study design and participants\n# Cognitive outcomes and analysis\n## BMI interaction results\n# Implications and future work","[{\"question\":\"What question does the study address about the MIND diet?\",\"answer\":\"Whether the effect of the MIND diet intervention on cognition differs across participants with different baseline BMI at enrollment.\"},{\"question\":\"How was cognitive change measured in this study?\",\"answer\":\"Global cognition change was assessed annually using a score derived from a battery of 12 neurocognitive tests.\"},{\"question\":\"What did the study find for participants with BMI greater than 35?\",\"answer\":\"Among individuals with BMI\\u003e35 kg/m2, the MIND diet group showed a slower rate of decline in global cognition compared with the control diet group.\"}]","EFFECT OF THE MIND DIET INTERVENTION ON COGNITION IN OLDER ADULTS WITH CLASS 2 AND 3 OBESITY | PDF",1790643804]
