Official title: Digital Intervention to Improve Diet Quality in Adolescents With Overweight or Obesity

Status Not yet recruiting

Clinical Trial Summary

The goal of this clinical trial is to compare the effectiveness of a mobile health intervention in adolescents (14-17 years) with overweight or obesity. The main question[s] it aims to answer are: 1) is a digital-based diet quality intervention for adolescents with overweight or obesity feasible and 2) is there preliminary effectiveness in improving diet quality? Participants will: 1. Complete three-day 24-hour dietary recalls 2. Collect urine samples 3. Wear a continuous glucose monitor, sleep tracker, and physical activity tracker Researchers will compare control and intervention groups to see if diet quality and meal timing traits improve as assessed by 24-hour dietary recalls, a novel urine biomarker, and continuous glucose monitoring (CGM).

Clinical Trial Description

Background: Improving diet quality is an essential component for the treatment of adolescent obesity. Pediatric providers are recommended to incorporate nutrition recommendations as part of adolescent obesity treatment, but time and knowledge are barriers. Digital-based interventions have been shown to improve fruit and vegetable intake in adolescents. However, it is unknown if a digital-based diet quality intervention is feasible or effective for adolescents with overweight or obesity. Objectives: (primary and important secondary objectives) The overarching objective of this pilot study is to demonstrate if a digital-based diet quality intervention for adolescents with overweight or obesity is feasible and if there is preliminary effectiveness that diet quality and meal timing traits improves as assessed by 24-hr dietary recalls, a novel urine biomarker, and continuous glucose monitoring (CGM). Study Design: A two-arm pilot randomized controlled trial (RCT) falling under the preparation phase of the Multiphase Optimization Strategy (MOST) framework. Setting/Participants: This is a single site study. Adolescents (N=14, aged 14-17 years) at risk for diet quality that is low or in need of improvement (Healthy Eating Index (HEI) < 80) and with a history of having overweight or obesity (body mass index (BMI) between the 85th and 99th percentile on at least two occasions six months apart in the medical record in the last five years) will be invited to participate. Clinical measurements will be acquired at the Children's Hospital of Philadelphia (CHOP). Diet, urine, blood glucose, physical activity, and sleep data collection will take place in the home setting. Study Interventions and Measures: Adolescents and their parents will be randomized to receive a) usual care or b) a nutrition intervention with personal goals, meal timing, nutrition skills, and home food environment intervention components. The content for each component will be delivered through text messaging. Three 24-hr dietary recalls and the first morning urine void on two separate occasions will be collected at baseline and follow-up. HEI-2020 scores will be calculated and change in HEI-2020 will be the primary outcome. The urine Na:K will be quantified and change in Na:K will be the secondary outcome. ;
