In stressful jobs, depression risk rises with hours worked, study in new doctors finds

The more hours someone works each week in a stressful job, the more their risk of depression rises, a study in new doctors finds. Working 90 or more hours a week was associated with changes in depression symptom scores three times larger than the change in depression symptoms among those working 40 to 45 hours a week. A higher percentage of those who worked a large number of hours had scores high enough to qualify for a diagnosis of moderate to severe depression.
