Among women, those who had never married were twice as likely to age optimally compared to married respondents who became widowed or divorced during the study period. Married women did not differ significantly from never-married women with respect to optimal aging.

"Little is known about the relationship between marital trajectories in old age and successful aging. Our goal was to see whether different marital trajectories were associated with physical health and well-being, and whether these relationships varied for men and women," says first author Mabel Ho, a recent doctoral graduate at the University of Toronto's Factor-Inwentash Faculty of Social Work (FIFSW) and the Institute of Life Course and Aging. The researchers defined optimal aging as freedom from any serious physical, cognitive, mental, or emotional conditions that prevent daily activities, as well as high levels of self-reported happiness, good physical health, and mental health.
