Working more than 45 work hours per week for at least 10 years may be an independent risk factor for CVD.

“ This research is a heads-up for hard working people. If you must, want to or just enjoy working more than 45 hours a week, counteract the risk factor by exercise, good consistent diet habits, stress control, good interpersonal relationships, mindfulness, good sleep habits and a regular lifestyle, not having wild variations in your weeks. This risk applies to most physicians in patient care; it is unavoidable. Their skills and knowledge are so needed, they have a strong reason to work excessively.” Bill Chesnut, MD.

Working long hours may be linked to higher risk of heart disease, study suggests

The New York Times (3/10, Bakalar) “Well” blog reports that research suggests “the more hours you work, the greater your risk for heart disease.” Investigators “found that for each additional hour of work per week over ten years, there was a 1 percent increase in the risk for heart disease.” The findings were published in the Journal of Occupational and Environmental Medicine. _________________Ama 3.10.1

Dose–Response Relation Between Work Hours and Cardiovascular Disease Risk: Findings From the Panel Study of Income Dynamics                 Conway, Sadie H. PhD; Pompeii, Lisa A. PhD; Roberts, Robert E. PhD; Follis, Jack L. PhD; Gimeno, David PhD

Objectives: The aim of this study was to examine the presence of a dose–response relationship between work hours and incident cardiovascular disease (CVD) in a representative sample of U.S. workers.

Methods: A retrospective cohort study of 1926 individuals from the Panel Study of Income Dynamics (1986 to 2011) employed for at least 10 years. Restricted cubic spline regression was used to estimate the dose–response relationship of work hours with CVD.

Results: A dose–response relationship was observed in which an average workweek of 46 hours or more for at least 10 years was associated with an increased risk of CVD. Compared with working 45 hours per week, working an additional 10 hours per week or more for at least 10 years increased CVD risk by at least 16%.

Conclusion: Working more than 45 work hours per week for at least 10 years may be an independent risk factor for CVD.
