Improving Insulin Resistance and Energy Metabolism Through Sleep Extension in Adolescents

University of Colorado, Denver10 enrolled

Overview

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.

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.

Conditions

Sleep Diabetes Mellitus, Type 2

Interventions

Extended Sleep InterventionBEHAVIORAL

Participants will receive an Extended Sleep Intervention (ES). Participants will be prescribed a sleep schedule that allows them to obtain approximately 1.5 h more time in bed compared to their typical sleep. Prescribed bedtimes and wake times will be determined collaboratively through discussion with participants and parents.
