How Does Neighborhood Engagement Affect the Association of Living Alone with Mental Disorder Risks in Older People?
Abstract Background: Social isolation has been increasingly recognized as a strong risk factor for health-related outcomes, yet, there is limited knowledge about the pathways linking living alone to later life psychological disorders. This study examines the influence of living alone on older people’s psychological disorders and explores the protective role of neighborhood engagement such as social participation and physical activity. Methods: We used cross-sectional data from a 2016/2017 Aging, Health, Psychological Wellbeing and Health-seeking Behavior Survey involving nationally representative sample of 1200 adults aged 50+ years in Ghana. The study focused on a latent measure of Kessler Psychological Distress Scale (K10) and on the General Practice Physical Activity Scale. Ordinary Least Squares models assessed the effect of living alone interactively with neighborhood characteristics on the indicator of mental disorder. Results: The results showed that living alone was independent predictor of poor mental disorder in the overall sample, among females, urban dwellers and all age groups. However, physical activity and social participation significantly buffered against these associations. In the stratified analysis, physical activity moderated the association for males, rural-dwellers and those 65+ years whilst social participation modified the association for females, urban-dwellers and those 50-64 years. Conclusions: Neighborhood characteristics strongly attenuate the positive association of living alone with mental disorders. These findings may inform intervention initiatives targeted at improving mental health of older people living alone.
