Long office hours may increase risk of heart disease

Employees pulling long hours at the office could be increasing the risk of contracting heart disease, a new study suggests.

The findings, published in the March edition of the Journal of Occupational and Environmental Medicine, suggest that the chances of full-time workers getting a cardiovascular disease (CVD) increase by one per cent for every additional hour worked a week , over a minimum of ten years.
 
The long-term study of 1900 full – and part-time workers found that 43 per cent had been diagnosed with a CVD-related problem such as angina, high blood pressure or coronary heart disease. 
 

Employees working 55 hours a week are 16% more at risk of CVD

Full-time workers were five per cent more likely to suffer from a CVD illness than part-time staff and those who had been diagnosed worked an average of 1.5 hours a week more than those who did not.
 
Beginning at 46 hours, increasing work hours were progressively associated with a higher risk of CVD. Compared to people who average 45 hours per week for ten years or longer, overall CVD risk was increased by 16 per cent for those who worked 55 hours per week and by 35 per cent for those who worked 60 hours per week.
 
This study provides specific evidence on long work hours and an increase in the risk of CVD prevention efforts.
