Michigan Weight Navigation Program (MiWeigh) Study

University of Michigan500 enrolled

Overview

The main purpose of this study is to determine whether people who participate in MiWeigh lose more weight than people who receive information about weight loss strategies and programs. The researchers also want to learn what parts of the program do and do not work and why. If the program is effective, the researchers want to learn how other health care systems could offer this program. The overarching aim of the MiWeigh Study is to better help patients prevent, manage, or reverse obesity-related chronic conditions.

Interventions

MiWeighBEHAVIORAL

Participants will complete a baseline assessment that includes a survey, blood draw, and body measurements. Participants will be given access to a website with information on weight-loss options and have at least one visit with a doctor that has special training in obesity medicine. Prior to this visit, clinical pre-surveys and additional laboratory blood tests will be completed. During this visit, the doctor will work with the participant to develop an individualized weight-loss treatment plan. Additionally, participants will report weight weekly via text and receive periodic supportive messages via the health portal or phone call.

Enhanced Usual Care (EUC)BEHAVIORAL

Participants will complete assessments at baseline and 12 months that include a survey, blood draw, and body measurements, plus a survey at 6 months. Once randomized, participants will be given access to a website with information on weight-loss options and advised to see their primary care provider if a participant wishes to discuss the options.
