Sleep duration affects risk for ulcerative colitis

Bethesda, MD (Oct. 21, 2014) — If you are not getting the recommended seven-to-eight hours of sleep each night, you may be at increased risk of developing ulcerative colitis, according to a new study1 in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association.

"Both short and long durations of sleep have important health implications and are associated with increased overall mortality, cardiovascular disease and cancer," said lead study author Ashwin N. Ananthakrishnan, MD, MPH, Massachusetts General Hospital. "Our findings indicate that ulcerative colitis may potentially be added to this list. We found that less than six hours of sleep per day and more than nine hours of sleep per day are each associated with an increased risk of ulcerative colitis."

In a previous study2, also published in Clinical Gastroenterology and Hepatology last year, Ananthakrishnan and colleagues had reported that poor sleep quality, even while in remission, resulted in a two fold increase in risk of Crohn's disease flares at six months. "All these data together support a growing recognition of the impact of sleep disruption on the immune system, and the need for providers to frequently inquire about sleep duration and quality as an important parameter of health in patients with inflammatory bowel diseases," said Dr. Ananthakrishnan.
