Life Satisfaction Domains Among Older Adults: Patterns by Age, Gender, and Living Arrangement.

This study examined age-related differences in total and domain-specific life satisfaction among older adults, stratified by gender and living arrangement. Cross-sectional data from 13,488 adults aged ≥65 years were analyzed across five domains: health, community environment, interpersonal relationships, society, and social roles. Using T-scores based on the 65-69 group, linear regression assessed associations between age and life satisfaction. Among men living with others, older age was linked to higher total life satisfaction and greater satisfaction with interpersonal relationships and social roles. No significant associations were found for men living alone, suggesting a different trajectory from typical psychological adaptation. Women living with others showed positive age-related trends across all domains. Women living alone also demonstrated significant increases in community environment, interpersonal relationships, and social roles, indicating that age-related improvements were present regardless of living arrangement.
