“Even though the absolute risk is small and the contribution of shift work to coronary heart disease is modest, it is important to note that this is a modifiable risk factor, and changing shift schedules may have an impact on the prevention of coronary heart disease.” These are all critical factors when thinking how to prevent coronary heart disease. However, even after controlling for these risk factors, we still saw an increased risk of coronary heart disease associated with rotating shift work,” said lead author Celine Vetter, an HMS instructor in medicine and a chronobiologist at Brigham and Women’s. “There are a number of known risk factors for coronary heart disease, such as smoking, poor diet, lack of physical activity and elevated body mass index. In a new study from Brigham and Women’s Hospital and Harvard Medical School published in the April 26 issue of JAMA, researchers found that women who work more than 10 years of rotating night shift work had a 15 to 18 percent increased risk of developing coronary heart disease, the most common type of heart disease, as compared with women who did not work rotating night shifts. Heart disease is the leading cause of death in the United States. ![]()
