Marital Satisfaction, Gender, and Active Social Engagement in Older Adults: Longitudinal Evidence From South Korea

Objectives: This study investigated the longitudinal association between marital satisfaction and active social engagement among older adults, while also considering potential gender differences in these associations. Methods: Seven waves of data from the Korean Longitudinal Study of Aging from 2006 to 2019 were utilized (N = 2,568, aged 65 or older). Fixed-effects Poisson regression models were employed to account for unobserved individual-level confounders. To capture active social engagement comprehensively, multiple activity types including social interaction, physical activity, travel activity, and volunteer activity were considered. An interaction model was used to examine potential gender differences. Results: The results of this study suggested that an individual's marital satisfaction is associated with an increase in their active social engagement. A one-standard deviation increase in marital satisfaction was associated with a 1.9%, 2.9%, 5.8%, and 18.1% higher incidence rate of engagement in social interaction, physical activity, travel activity, and volunteer activity, respectively, after accounting for individual-specific factors. The associations for social interaction and travel activity were largely driven by older men. In contrast, the associations for physical activity and volunteer activity were similar for older men and older women. Discussion: Marital satisfaction plays a crucial role in fostering active social engagement among older adults. Interventions designed to address social and financial obstacles within marital relationships among older adults could effectively improve their health and well-being by promoting various types of activities. The impact of these interventions may differ based on gender and the specific types of activities involved.
