Synchronous vs Asynchronous Remotely Delivered Lifestyle Interventions

A Non-Inferiority Trial Comparing Synchronous and Asynchronous Remotely Delivered Lifestyle Interventions

Sponsor

328 participants

Study Type

INTERVENTIONAL

Conditions

Obesity

Summary

The goal of this clinical trial is to learn if a group-based digital weight loss program that is delivered asynchronously (via an online platform) is as effective as one that is delivered synchronously (via weekly videoconference meetings). In the asynchronous condition, participants can engage with their group any time 24/7. In the synchronous condition, participants can engage with their group once a week at a videoconference meeting. The main questions it aims to answer are: Will participants in each condition lose about the same amount of weight? Will the participants in the asynchronous condition participate more than those in the synchronous condition? Will the participants in the asynchronous condition feel more connected to each other than those in the synchronous condition? Will the asynchronous condition cost less to deliver per pound lost than the synchronous condition? Participants will: Receive a digital weight loss program that lasts 1 year and then volunteer participants will be selected to lead the group for 1 year following the program, a phase called the "peer-led weight loss maintenance phase." Complete study assessments at baseline, 6, 12, 18, and 24 months.

Plain Language Summary

Simplified for easier understanding

This study compares two formats of a digital group-based weight loss program: one where participants meet weekly via videoconference (synchronous) and one where they can interact with their group anytime via an online platform (asynchronous). Researchers want to know whether the more flexible asynchronous approach produces similar initial weight loss but better long-term maintenance, greater engagement, and lower cost than scheduled meetings. Eligible participants are adults with a BMI of 27–45 who have a smartphone, home internet with a smart scale, and use Facebook actively at least 5 days per week; those who are pregnant, have had bariatric surgery, or are currently taking weight-affecting medications are excluded. Participation involves joining a 1-year digital weight loss program followed by a 1-year peer-led maintenance phase, with weight and behavioral assessments at 6, 12, 18, and 24 months. This summary was prepared using AI to help patients understand the study in plain language.

Interventions

BEHAVIORALAsynchronous Remote Lifestyle Intervention

A 1 year lifestyle intervention based on the Diabetes Prevention Program to be delivered asynchronously via a private Facebook group led by a professional weight loss counselor. In the subsequent year, a Peer-Led Maintenance Phase will occur in which a participant volunteer will lead the group after receiving a brief training.
