2020 Annual Report
Objectives
Objective: Examine the acute effects of sedentary behaviors on energy metabolism and cardiometabolic health in Latino adolescents, after adjusting diet.
Approach
Researchers will utilize whole-room calorimetry to examine the effects of an acute bout of sedentary behaviors on cardiometabolic outcomes (glucose, insulin, lipids, arterial stiffness) and energy metabolism (energy expenditure, substrate utilization) in Latino adolescents (12-16 years old) with obesity (BMI% '95th) as compared to non-Latino white adolecents (12-16 years old) with obesity (BMI% '95th). Findings from this study will increase our understanding of the contributions of sedentary behaviors to the development of cardiometabolic diseases in high-risk youth. This information will inform future behavioral interventions aimed at reducing sedentariness to reduce disease risk and address health disparities in Latino youth.
Progress Report
For Objective 1, our research project has been submitted to the Institutional Review Board. Research personnel have been hired and will be trained to conduct and coordinate all research activities for this study. This training will include the protection of human subjects, careful handling of sensitive data, and policies and procedures, which have been revised due to the COVID-19 pandemic. Training will also address learning, developing, and implementing recruitment strategies, consenting, and participant intake. Using the study protocol, research personnel will learn to conduct data collection activities including measuring anthropometrics, arterial stiffness, and assisting staff with providing participant supervision in the calorimeter and collecting blood draws to assess cardiometabolic risk factors. Lastly, the training will include data entry and preliminary descriptive analysis.
