Abstract: Quality of life (QOL) at the end of life often declines in relation to various determinants, yet the role of social determinants, including social capital, in end-of-life care is frequently overlooked. This study aims to examine the association between social determinants and QOL in the last year of life and to test the mediating role of social capital in the relationship between social determinants and QOL among older adults with multimorbidity (MM). We used secondary data from the National Health and Aging Trends Study (NHATS) in Rounds 10 and 11, involving 3,085 adults aged 65 and older. The final analysis comprised 230 participants. Multiple linear regression was conducted to assess the associations between social determinants and QOL, and path analysis was used to evaluate the mediating effect of social capital. The regression model showed that social capital was positively and significantly associated with QOL (β = 0.378, 95% CI [0.099, 0.657], SE = 0.139), as were mental conditions (β = 0.614, 95% CI [0.167, 1.062], SE = 0.194). The mediation analysis demonstrated that social capital functioned as a complementary mediator, partially mediating the relationship between mental conditions and QOL in the last year of life. These findings underscore the potential role of social capital in enhancing QOL at the end of life, particularly through its influence on mental health. The study highlights the need for healthcare practices and policies that promote social support systems and community-based care for older adults with MM. By addressing social capital, end-of-life care could be improved, resulting in better overall well-being for individuals facing the last stages of life.
