Purpose
This study aimed to investigate the distinct yet interconnected aspects of social isolation, namely living alone and loneliness, and their individual and combined effects on predicting health-related quality of life (HRQoL).
Methods
A comprehensive analysis, encompassing both cross-sectional and longitudinal approaches, was conducted using a nationally representative sample of 5644 community-dwelling adults aged 55 and older from the Healthy Aging Longitudinal Study in Taiwan (HALST).
Results
Baseline data revealed that 9% of the sample reported living alone, while 10.3% reported experiencing loneliness, with 2.5% reporting both living alone and feeling lonely. Regression analyses consistently demonstrated that loneliness was significantly associated with concurrent and subsequent lower physical (PCS) and mental (MCS) component of HRQoL. Conversely, additional analyses indicated that living alone could indirectly exacerbate the adverse effects of loneliness or contribute to prolonged feelings of loneliness, subsequently predicting lower HRQoL after 3.2 year.
Conclusion
In terms of practical implications, interventions and policies aiming to enhance HRQoL in older adults should give particular attention to those who report feelings of loneliness, especially individuals living alone.
