The Impact of Living Arrangements on Depressive Symptoms by Gender Among Community-Dwelling Older Adults in Japan

This study examines the relationship between living arrangements and depressive symptoms among community-dwelling older adults in Japan, with a particular focus on gender differences. A cross-sectional survey was conducted in Ayase City, Kanagawa Prefecture, using mailed questionnaires, and the analysis was conducted on data from 1409 participants aged 65 and older. Logistic regression analysis was performed to assess the associations between living arrangements, social networks, social participation, and depressive symptoms, adjusting for sociodemographic and health-related factors. The findings indicate that older adults living alone and those co-residing with their children are particularly vulnerable. Those living alone were more likely to be women aged 75 and older, with economic difficulties, and exhibited higher rates of depressive symptoms and care needs. Similarly, older adults living with their children had a higher prevalence of depressive symptoms and care requirements despite experiencing fewer economic hardships. This group was also characterized by lower educational attainment. Additionally, gender-specific factors were identified in the relationship between social relationships, including living arrangements, and depressive symptoms. These results underscore the necessity of interventions that consider both living arrangements and gender-specific social factors to mitigate mental health risks among older adults.
