Association between body mass index (BMI) and clinical dementia rating (CDR) categories, excluding participants with cancer and current smokers (n = 575).

Reference: CDR 0 (without dementia).

CDR 0.5 (questionable dementia), CDR 1 (mild dementia), CDR 2 (moderate dementia), and CDR 3 (severe dementia).

Model 1: linear regression model, adjusted for age, sex, race, and education.

Model 2: linear regression model, adjusted for age, sex, race, education, hypertension, diabetes, coronary artery disease, heart failure, dyslipidemia, physical inactivity, and alcohol use.
