Social engagement and cognitive health in a population-based study of older men and women in rural South Africa
We investigated how patterns of social engagement and cognitive health in theHAALSI population-based study of over 5000 individuals aged ≥ 40 years in rural South Africafit with three existing theories of how social engagement and cognitive function areinterconnected in older age. We found that respondents with lower cognitive function hadsmaller, denser social networks that were more local and more kin-based than their peers.Lower cognitive function was associated with receipt of less social support in general, but thisdifference was stronger for emotional and informational than for financial and physicalsupport. These patterns suggest that cognitively impaired older adults in this setting rely ontheir core social networks for support, and that theories developed in higher-income andhigher-education settings may also apply elsewhere in the world.
