Vigorous physical activity, exercise and a brisk walking pace can lower the risk for incident type 2 diabetes in adults; whereas increased sedentary behavior and television watching time can increase the risk, according to recent study findings.
Joshua J. Joseph,
MD, clinical and research fellow at Johns Hopkins University School of Medicine in Baltimore, and colleagues analyzed data from 5,829 adults participating in the Multi-Ethnic Study of Atherosclerosis (MESA), a population-based study of four racial groups without diagnosed cardiovascular disease or diabetes at baseline (mean age, 62 years; 54% women; 42% white; 12% Chinese; 26% black; 21% Hispanic). Participants completed a Typical Week Physical Activity Survey to assess baseline moderate, vigorous and exercise-specific physical activity, and metabolic equivalents of task-hours per week and sedentary behaviors (television watching, reading; hours/day). Incident diabetes was assessed in five in-person examinations between 2002 and 2012. Researchers used Cox proportional hazard models to estimate HRs.
