Social Support, Health Behaviors, Self-Esteem, and Successful Aging in a Sub-Saharan African Sample of Older Adults: Test of a Sequential Mediation Model.

Background and Objectives: Previous research demonstrates that social support facilitates successful aging across all cultures. However, the factors that potentially mediate the link between social support and successful aging remain unclear. This study examined whether a healthy lifestyle and self-esteem mediate the association between social support and successful aging. It was hypothesized that the relationship between social support (family, friends, and significant other) and successful aging would be serially mediated by both healthy lifestyle and self-esteem. Research Design and Methods: Participants were 479 Nigerian retirees (53.4% female) aged 60 to 90 years ( Results: Controlling for age and sex, family support, significant other support, friends support, healthy lifestyle, and self-esteem were directly associated with successful aging. The association between family support and successful aging was mediated by healthy lifestyle; and this was also seen for friends' support and significant other support. The sequential path from social support to successful aging through healthy lifestyle, and then via improved self-esteem, was significant for family support and significant other support, but not friends support. Discussion and Implications: Findings suggest that middle-aged to older adults who have strong support from their families and significant others may be more likely to engage in healthy behaviors and, in turn, experience higher levels of self-esteem, thereby aging well.
