Improving Insulin Resistance and Energy Metabolism Through Sleep Extension in Adolescents

Not Applicable

Completed

• Conditions: Sleep; Diabetes Mellitus, Type 2

• Registration Number: NCT03814512
• Lead Sponsor: University of Colorado, Denver

Brief Summary

The investigators propose to deliver a 4-week sleep extension intervention to adolescents to evaluate feasibility of the protocol and obtain preliminary data on intra-individual changes in metabolic parameters induced by sleep extension.

Detailed Description

The specific aims of this feasibility study are to 1) examine the feasibility of recruitment and retention of adolescents with overweight/obesity, pre-diabetes, and inadequate sleep into a sleep extension intervention; 2) assess adherence of a sleep extension intervention to increase total sleep time in adolescents with overweight/obesity, pre-diabetes, and inadequate sleep; 3) determine estimates of mean and variability of potential intervention outcomes including metabolomic, body composition, and substrate oxidation. The investigators propose to deliver a 4-week sleep extension intervention to adolescents to evaluate feasibility of the protocol and obtain preliminary data on intra-individual changes in metabolic parameters induced by sleep extension.

This proposal is the first step to demonstrate feasibility in delivering the intervention in a research setting, measure the effect of the intervention on changing sleep duration, and examine changes in obesity-related IR metabolites that would lead to improved IR in an adolescent population with pre-diabetes. The long-term goal is to disseminate an effective and feasible T2D prevention program that can be sustainably implemented in clinical weight management settings.
