closeLong work hour and depression possibly mediated by short/insufficient sleep?
Posted by akisan67 on 28 Mar 2012 at 16:11 GMT
First of all, I congrat your study for a through well done! One thing that authors may worth looking at is the potential effect of short/insufficient sleep combined with work hours causing depression. It is often the case that long wok hours cause short sleep leading to poor sleep. I believe that the main factor that caused MDE was an indirect effect of long work hours leading to insufficiant sleep (J Clin Psychiat 2011 72 605-614).

Thank you for the positive feedback. You are correct, the evidence shows that people who work long hours more often have short sleeping hours and sleep disturbances. The paper you cite hypothesises that the association may be dependent on whether long hours affects the quality/quantity of sleep. Indeed, sleep disturbances are an integral feature of depression. It would be important to examine in larger longitudinal datasets whether maintaining good sleep would protect employees who work long hours from developing depression.
