A new study based on an analysis of the residents of Turin, Italy, a city of over 900,000, reveals that walkable access to public transit and urban services benefits mental health, particularly for women and seniors.

An elderly Asian women asked if she could join me due to the limited seating, and we soon struck up some small talk. She lived nearby in her 47-year-old son's home, and she told me of all the transit—bus, light rail, and streetcar lines near her home, particularly which ones took her to Japantown. She called the buses her "limousines" because they would drop her off right in front of her home.
Along comes this study published in the International Journal of Environmental Research and Public Health that completely validates everything she said. Access to multiple transit lines and living within walking distance to a vibrant business district appears to be contributing to this senior's mental (as well as physical) health.
"For the study, a group of Italy-based researchers gathered long-term data on Turin residents," writes Eric Jaffe, CityLab’s New York bureau chief...."Of the environmental factors, density and transit access proved “protective” of mental health, especially for women (of all ages) and older people (age 50 to 64)."
These populations were prescribed fewer antidepressant drugs when they lived in places reached more quickly by bus or train, in places with taller average building heights, compared with counterparts in more remote or sparse areas. That connection held up even when social factors were taken into account.
A look through Planetizen posts tagged 'mental health' shows no lack of articles showing a nexus with green spaces or trees, yet the Turin study showed no such connection "between mental health and public green space," writes Jaffe. "That’s surprising considering the vast evidence supporting this link." [See 'related' below.]
Conclusion from the study's abstract:
Therefore, this research suggests that good accessibility to public transport, as well as a dense urban structure (versus sprawl), could contribute to reduced risk of depression, especially for women and elderly, by increasing opportunities to move around and have an active social life.
