Older women living only with husbands face most depression, Japan study finds

Older women in Japan who live only with their husband can expect to spend a larger share of their remaining life with depression than women in any other living arrangement, according to a study by researchers at Sophia University and Nihon University that was publicised on Wednesday, 11 November 2026. Among women aged 65 and over, those living only with a spouse were expected to spend 25.0% of their remaining years with depression, compared with 16.3% for women living with other family members. For men, the pattern was the opposite: those living alone fared worst.

Most research on loneliness in old age has focused on people who live alone, and the authors note that earlier work concentrated on that risk. This study adds a different warning: for older women, living as a couple is not automatically protective. The study does not explain why women in couple-only homes fared worst, and the authors' data do not test reasons such as caregiving load. What the numbers do show is a group of older women whose risk would be missed if attention went only to people living alone.

For men, the findings fit the more familiar picture: older men living alone were the most exposed to depression. The gender split matters for anyone planning support for older people. A single approach, such as only checking on those who live alone, would miss many women at risk.

Japan's ageing pattern is relevant beyond Japan. The authors describe a country where fewer older people live with their adult children and more live alone or only with a spouse. The Japanese data cannot be applied directly to India or other countries, but they raise a question families and health workers anywhere can ask when older parents live as a couple on their own: how is the older woman in the home doing, not just her husband?

Peepals calculation: The gap between the two groups of women is 8.7 percentage points (25.0 − 16.3). Put another way, women living only with a spouse were expected to spend about 1.5 times as large a share of their remaining years with depression as women living with other family (25.0 ÷ 16.3 ≈ 1.53). If a woman had 20 years of life left, 25% would mean about 5 years with depression, against about 3.3 years at 16.3%. Our calculation from the reported figures.

Short-term: The findings give doctors, counsellors and families a reason to ask older women in couple-only homes about low mood, not only those who live alone.

Long-term: As more older people live alone or only with a spouse, health systems may need support that reaches both groups, including older wives, not only those who live alone.

Who is affected: Older women living with their husbands, older men living alone, their families, and the health and social workers who support them.
