Epidemiological studies demonstrate a beneficial effect of physical activity (PA) on various biological health outcomes associated with diabetes; however, these studies have been limited by the use of self-report measures of PA. To provide the most accurate association between PA and health among adults with diabetes, the purpose of this study was to examine the association between accelerometer-assessed PA and numerous biological markers associated with diabetes. Data from the 2003-2006 National Health and Nutrition Examination Survey were used. Adult participants with diabetes were included in the present study and wore an ActiGraph 7164 accelerometer. Light and moderate-to-vigorous PA (MVPA) intensity was determined from accelerometer-derived estimates. Various biological measures, such as triglycerides and C-reactive protein, were measured from a blood sample. Results showed that both light-intensity and MVPA were inversely associated with several biological health outcomes. Additionally, active adults were less likely to have multiple cardiovascular disease risk factors. Findings also differed by age and gender, suggesting that PA interventions may need to consider the influence that age and gender may have on the efficacy of physical activity interventions.
