As traditional multigenerational households have become less common, increasing numbers of older adults are living alone or with only their spouses. Over the last few decades, Japan has been experiencing two major demographic changes: a rapidly aging population and a shift in how older adults live. These changes have important implications for health and well-being in later life, as living arrangements can shape social support, companionship and caregiving responsibilities.
Living alone is often associated with social isolation and depression. However, the mental health implications of other living arrangements remain to be explored. Living with family members may offer companionship and support, but it may also come with the burden of caregiving responsibilities. At the same time, these experiences may differ between men and women. How are living arrangements associated with the number of remaining years older adults can expect to live with and without depression?
To address this question, associate professor Yuka Minagawa of the Faculty of Liberal Arts at Sophia University, Japan, and professor Yasuhiko Saito of the College of Economics at Nihon University, Japan, examined the relationship between older adults' living arrangements and depression in a study published in the Journal of Aging and Health on Sept. 9, 2026.
Minagawa explains, "Living arrangements among older adults in Japan have changed substantially over the past few decades, with declining percentages of intergenerational co-residence and increasing numbers of older adults living alone or with their spouse only." While previous research has focused on health risks associated with living alone, less is known about how other household arrangements shape older people's mental well-being.
Drawing on 10 years of data collected between 1999 and 2009 from the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA), the researchers used a statistical method known as multistate life table analysis and estimated the expected number and proportion of remaining years spent with and without depression among adults aged 65 and older. They compared three living arrangements—living alone, living only with a spouse and living with other family members—and examined differences between men and women.
The findings revealed distinct gender differences. At age 65, men living alone were expected to spend 24.7% of their remaining lives with depression, compared with 13.1% among men living with other family members. Among women, the greatest proportion was observed among those living only with a spouse, at 25.0%. By comparison, women living with other family members were expected to spend 16.3% of their remaining lives with depression. These estimates highlight that living alone is not the only arrangement associated with less favorable depression-related outcomes in later life.
The study findings have implications for policies and support programs aimed at promoting mental well-being among older adults. While social connection and access to mental health services may be particularly important for men living alone, support should also address the needs of women living with their spouses. One possible consideration is the burden of family caregiving, which may affect women's well-being.
"Our study highlights the importance of gender-sensitive approaches to promoting mental well-being in later life. Living alone is often associated with social isolation and poor mental health, but living with a spouse may also be detrimental, especially among women. This point suggests how women shoulder the burden of family caregiving at advanced ages at the expense of their own well-being. Support programs should therefore extend beyond older adults living alone to include those in other living arrangements, with particular attention to gender differences," explains Minagawa.
In the longer term, recognizing that mental health risks vary by gender and living arrangement could help policymakers develop more targeted, gender-sensitive interventions. Promoting mental well-being in later life requires ensuring that support reflects the different circumstances in which older adults age.
