Abstract
We investigated whether functional social support-the degree to which one perceives support is available when needed-is associated with executive function, a key cognitive domain for everyday functioning and adaptation to change. Analyses (n = 23,491) utilized cross-sectional data from the Comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA), a population-based study of community-dwelling adults aged 45-85years. Executive function was assessed by neurocognitive battery. Perceived social support was measured using the 19-item Medical Outcomes Study-Social Support Survey. Logistic regression models were adjusted for sociodemographic, health, and social covariates. Positive social interactions as well as affectionate and emotional/informational functional social support were positively associated with executive function. Social support plays an important role in cognitive health. Diversifying social programming beyond tangible social support to target other subtypes of support may help preserve executive function in middle-aged and older adults.
