Sex differences in the effecTs of brEaking uP sedentary behavior on vascUlar function in Type 2 Diabetes (STEP UP T2D)
Type 2 diabetes (T2D) confers a high risk of cardiovascular disease (CVD), particularly among older adults who tend to be physically inactive. Most studies that have examined the effects of changing sedentary behavior (SB) have focused on young healthy males and prioritized glycemic outcomes. We will look at the effect of 3 different ways of breaking up sitting: 1) 4 hours of prolonged SB, 2) 4 hours of SB broken up by 5 minutes of self-paced walking every hour, and 3) 4 hours of SB with one 20-minute bout of self-paced walking. In addition to examining the overall effects of each condition, differences between men and women will be evaluated.

The TrialNet Natural History Study of the Development of Type 1 Diabetes
TrialNet is an international research group dedicated to the study, prevention, and early treatment of Type 1 diabetes. Type 1 diabetes is now understood as a disease that develops over time in stages. Stage 1 starts with the appearance of having two or more autoantibodies. This is followed by Stage 2, which is the development of abnormal blood glucose levels. Stage 3 is the clinical diagnosis of Type 1 diabetes. This study will help us learn more about how Type 1 diabetes occurs through the screening of diabetes-related autoantibodies and monitoring individuals who have tested positive for these autoantibodies.
