Kyoto, Japan – Working long hours in a high-demand job increases the risk of developing depression, a new study from the Kyoto University School of Public Health concludes.

Researchers analyzed four surveys of more than 200 clerical workers – conducted in the late 1990s and early 2000s – who were asked how many hours they worked per week, how demanding their job was, and about their well-being. Employees who worked at least 60 hours a week and reported “usually” having too much work to do were at a higher risk of depression, according to the study. This risk increased over time.

The risk of a major depressive disorder could be reduced through targeted mental health measures, including a change in a worker’s hours or job demands, the study authors suggested.

The study was published in the August issue of the Journal of Occupational and Environmental Medicine.
