Exercise cuts CV and all-cause mortality in diabetes
In patients with diabetes mellitus, even moderate levels of regular exercise can reduce risk of death by up to 38%, according to a newly published study that combines prospective cohort data with a meta-analysis of 12 previous studies [1].
The new study is published online August 6, 2012 in the Archives of Internal Medicine.
The authors, led by Diewertje Sluik (German Institute of Human Nutrition Potsdam-Rehbrücke, Nuthetal, Germany), note that physical activity has long been considered a cornerstone of diabetes management. However, they write, “Several prospective cohort studies have found that higher physical-activity levels were associated with reduced CVD and total mortality rates, but conclusive high-level evidence is lacking.”
Therefore, the researchers conducted a prospective cohort study of 5859 patients with diabetes who had been enrolled from 1992 to 2000 in the ongoing European Prospective Investigation Into Cancer and Nutrition Study (EPIC). Participants ranged in age from 35 to 70 years.
“No information was available to distinguish type 1 and 2 diabetes mellitus,” the authors write. “To be considered diabetic, a self-reported diagnosis at baseline had to be confirmed by at least one additional information source.”
