WASHINGTON: British white collar workers who spent 11 hours or more at work each day faced double the risk of depression as those who worked seven eight hours a day, said a study available on Wednesday.
The research, in print in the open access science journal PLoS ONE, follow more than 2,100 civil servants who had no previous depressive episodes or psychological risk factors for an average of nearly six years.
Those who worked long days were 2.3 to 2.5 era more likely to have a major depressive episode, said the study led by Marianna Virtanen of the Finnish organization of professional Health and University College London.
The link remained the same even at what time researchers made adjustments for factors such as alcohol and drug use, social support or lack thereof, and strain at work.
motionless the total number of depressive cases was only 66, or a rate of 3.1 percent, less ordinary than the five percent rate seen in the general population.
Although infrequently working overtime may have reimbursement for the person and society, it is important to recognize that working extreme hours is also associated with an increased risk of major depression, said Virtanen.
The study did not draw conclusions about why the link exists, but said it might be related to factor that were not studied such as labor family conflicts, prolonged increase in stress hormone levels and difficulty unwinding after work.
Also, since the study was limited to British civil servants, a larger inhabitants sample would be needed to determine if the link exists among blue collar workers or private sector employees, its authors said.
