Too much work doubles depression risk
Washington, Jan 31: People who work 11 or more hours a day are more than two
times likely to go through major depression compared to those working seven to
eight hours a day, a new study has warned.
The researchers, led by Marianna Virtanen of the Finnish Institute of
Occupational Health and University College London, followed about 2000 middle
aged British civil servants and found a robust association between overtime work
and depression.
This correlation was not affected when the analysis was adjusted for various
possible confounders, including socio-demographics, lifestyle, and work-related
factors.
There have been a number of previous studies on the subject, with varying
results, but the researchers emphasize that it is hard to compare results across
these studies because the cut-off for “overtime” work has not been standardized.
“Although occasionally working overtime may have benefits for the individual and
society, it is important to recognize that working excessive hours is also
associated with an increased risk of major depression,” said Dr Virtanen.
The study was recently published in the online journal PLoS ONE.
