Objectives: More frequent engagement in social activity is often associated with better physical health outcomes. Yet, less is known about whether engagement in a greater variety of social activities such as a mix of volunteering and attending club meetings (social activity variety) is important for health. The current study assessed whether social activity variety relates to mortality risk after adjusting for social activity frequency, non-social activity frequency and variety, and sociodemographic covariates, and how this relationship varies depending on age.
Method: Using data from the Health and Retirement Study (HRS), we included 5,017 adults aged 51 and older who completed questions about social activity participation in 2008 and whose mortality status was recorded up to 2019. We also examined whether age moderated the relationship between social activity variety and mortality risk.
Results: Cox proportional hazard model analyses revealed that those with higher activity variety in social activities were more likely to survive over the following 11 years than those with low social activity variety. Moreover, age moderation indicated that the association between social activity variety with mortality risk was stronger among the oldest adults.
Discussion: Findings suggest that a greater variety of social activities is linked to mortality risk even after adjusting for social activity frequency, non-social activities, and health status across adulthood.
