Effects of Multi-day Interruptions in Sitting on Type 2 Diabetes-relevant Outcomes in Children

Summary

The overall objective of this in-lab randomized controlled trial is to test the efficacy of multi-day interruptions in sedentary behavior vs. single bouts of sustained exercise on metabolic, cognitive, affective, and cardiac autonomic nervous system responses in children with overweight and obesity who are at risk for type 2 diabetes. The use of continuous glucose monitoring will provide insight into the daily and cumulative metabolic effects of each condition that have thus far not been studied. In-lab studies demonstrating sustained efficacy of this approach in ameliorating negative effects of sedentary behaviors in children are necessary for the optimization of field-based interventions. Given the lack of success of interventions to prevent obesity-related diseases and increasing rates of type 2 diabetes in children and its related healthcare costs, this study addresses a critical public health need by testing of novel intervention strategies to reduce obesity-related diseases in children with overweight and obesity.
