Research Project: Acute Effects of Sedentary Behaviors on Cardiometabolic Risk in Latino Youth

Location: Children's Nutrition Research Center

Project Number: 3092-51000-063-003-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Apr 8, 2020
End Date: Sep 30, 2023

(1) Examine the acute effects of sedentary behaviors on energy metabolism and cardiometabolic health in Latino adolescents, after adjusting diet. (2. NEW) To assess the feasibility and acceptability of a digital cooking intervention among low-income parents of 6-11 year-old children.

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. Researchers will use the Healthy Cooking Index to create a tailored, digital cooking intervention with the goal of improving cooking practices among low-income parents and, in turn, increasing the diet quality of their children. The primary objective of this study is to develop and test a digital cooking intervention in low-income parents of 6-11 year-old children in a single arm, prospective feasibility trial. Intervention development will be informed by qualitative formative research.
