Key Determinants of Physical and Psychological Health-Related Quality of Life Over Time Among Midlife and Older LGBTQ and Sexual and Gender-Diverse Caregivers.

Abstract

Prior research has shown informal caregiving among older adults can negatively affect the caregiver's physical and psychological health. However, little is known about protective and risk factors associated with the health-related quality of life (HRQOL) of lesbian, gay, bisexual, transgender, and queer (LGBTQ) caregivers. Informed by the Health Equity Promotion Model and Caregiver Stress Process Model and utilizing longitudinal data from Aging with Pride: National Health, Aging, and Sexuality/Gender Study, this analysis examined modifiable risk and protective factors associated with psychological and physical HRQOL over time among 754 LGBTQ caregivers aged 50-98. Psychological and physical HRQOL declined over a 3-year period. After controlling for background characteristics, mastery, social support, socialization, LGBTQ community engagement, and physical activity were positively associated with psychological HRQOL while day-to-day discrimination, identity stigma, and insufficient food intake were negatively associated. Steeper declines were observed for older and with no physical activity. Mastery, social support, socialization, and physical activity were positively associated with physical HRQOL while day-to-day discrimination and insufficient food intake were negatively associated. Steeper declines were found for those with high mastery and no physical activity. Although generalized factors including mastery, socialization, and social support are protective for HRQOL among LGBTQ caregivers, factors including day-to-day discrimination and identity stigma are more unique to historically disadvantaged populations and should be considered in future research and practice. Caregiving interventions incorporating physical activity are promising given its buffering effect for decreased physical and psychological HRQOL over time.
