Men who spend most of the day sitting might be increasing their chance of colorectal cancer, a researcher said.
In a pooled analysis of participants from two phase III clinical trials, men who were largely sedentary had an increased risk of recurring adenomatous polyps, according to Christine Sardo Molmenti, PhD, ofColumbia University Mailman School of Public Health in New York City.
On the other hand, there was no link between recurrence and sedentary behavior among women, Sardo Molmenti told reporters at the American Association for Cancer Research prevention conference in National Harbor, Md.
The clinical implication, she told MedPage Today, is that "clinicians should be encouraging patients to move, to stand, or really to do anything but stay in a sitting position for a large portion of time."
"There's a lot of value for these light, household activities, where you're not completely at rest, but you're not breaking a sweat to work out," she said.
The report comes the same week that European researchers also targeted sedentary behavior as a player in the development of metabolic syndrome and cardiovascular disease.
Doctors have tended to focus on the benefits of activity, rather than the risks of inactivity, commented Paul Limburg, MD, of the Mayo Clinic in Rochester, Minn., who was not part of the study but who moderated a press conference at which some details were presented.
