Association Between Body Mass Index and Cognitive Function
| Cognitive Domain | Continuous BMI | BMI Categorya | |||
|---|---|---|---|---|---|
| β | OR (95% CI) | Normal | Overweight | Obesity | |
| Memory | .04* | .96 (.94–.98)** | .06 (.03) | .08 (.02) | .11 (.02) |
| Speed-Attention | .02 | .97 (.94–.99)** | .05 (.03) | .13 (.02)* | .08 (.02) |
| Visuospatial Ability | .02 | .99 (.97–1.01) | .12 (.03) | .13 (.02) | .14 (.02) |
| Language | .01 | .98 (.96–1.00) | 17.41 (.26) | 17.09 (.20) | 17.49 (.18) |
| Numeric Ability | −.04* | 1.00 (.98–1.02) | 526.14 (1.20) | 524.23 (.90) | 523.31 (.83) |
Note. N=2,593. Analytic ns range from 2,272 (Numeric Reasoning) to 2,569 (Memory and Language) due to missing data. BMI=body mass index. OR=odds ratio. CI=confidence interval. Analyses control for age, sex, race, Latinx ethnicity, and education.
a
N=2,249 due to complete data on all cognitive measures and exclusion of participants in the underweight BMI category (n=23). Results were similar if these participants were included.
