Abstract
OBJECTIVES
To explore associations among cognition, frailty, and obesity in older adults.
DESIGN
Descriptive, secondary analysis of baseline data from two related lifestyle intervention trials.
SETTING
Clinical study open to civilian population through the Center for Translational Research on Inflammatory Diseases at the Veterans Affairs Medical Center in Houston, TX.
PARTICIPANTS
One hundred eight community-dwelling adults with obesity, aged 65 or older, recruited consecutively from two lifestyle intervention trials.
MEASUREMENTS
Cognition was assessed using Composite Age-Adjusted Scale Score from the National Institutes of Health Toolbox Cognition Battery: Obesity was assessed by body mass index (BMI) and also by truncal fat mas via dual energy x-ray absorptiometry. Frailty was assessed using the Physical Performance Test.
RESULTS
A significant linear regression model for cognition revealed frailty as the strongest predictor, followed by sex, and then truncal fat (R2=0.340, p<0.001).
CONCLUSION
Cognition among community-dwelling older adults with obese BMI may worsen with greater truncal fat mass. Frailty appears to be an important predictor of cognitive performance in this population.
