PURPOSE OF THE STUDY: This study examined whether the social environment moderates the relationship between the APOE e4 allele and cognitive functioning.
DESIGN AND METHODS: The Aging, Demographics, and Memory Study (ADAMS) data and multinomial logistic regression models were used to investigate these relationships for a nationally representative sample of U.S. adults aged 70 and older (n = 779).
RESULTS: Living alone (relative risk ratio [RRR] = 5.814; p = .000) and self-reported loneliness (RRR = 1.928, p = .049) were associated with a greater risk of cognitive difficulty. Living arrangements, perceived social support, and loneliness were found to moderate the relationship between the APOE e4 allele and cognitive function.
IMPLICATIONS: The results support the need to consider the social context when examining cognitive well-being in later life. These findings also indicate a need for the development of policies and services that promote a rich social environment.
