Working Long Hours Associated With Increased Risk of Stroke
People who work long hours are at higher risk of experiencing stress, poor work-life balance, tiredness, and lack of attentiveness. Now a new study has found that working long hours may also increase the risk of stroke.
For their study, the researchers used data from the CONSTANCES study, a population-based study that included 143,592 participants. The participants filled out a questionnaire at the beginning of the study that included information on age, smoking, and working hours. Information on cardiovascular risk factors and previous occurrence of stroke were obtained through a medical interview. The researchers defined long working hours as 10 or more hours daily for at least 50 days per year.
The researchers found that 29% of the participants reported working long hours and 10% reported working long hours for 10 years or more. Participants who reported working long hours had a 29% greater risk of stroke compared to those who did not. Those who reported working long hours for 10 years or more had a 45% increased risk of stroke. This association was stronger for people under the age of 50.
The study was conducted by researchers from Paris Hospital, Versailles and Angers University and the French National Institute of Health and Medical Research. It was published online ahead of print on June 20, 2019 in the journal Stroke.
