Summary

This trial will test whether a weight-loss program with peer support is more effective than a self-directed program.

Who is the study for?
This trial is for adults aged 21-75 with obesity (BMI of 30-50) who are getting care at participating practices. It's not for those with uncontrolled high blood pressure, recent heart issues, certain severe diseases, or on specific medications like antipsychotics or weight loss drugs. People who can't consent, follow the study plan, or might move away soon can't join.
What is being tested?
The study is testing if a weight management program in primary care guided by peer coaches helps people lose more weight compared to managing their own weight without such support. Participants will be randomly assigned to one of these two approaches.
What are the potential side effects?
Since this trial involves lifestyle interventions rather than medication, side effects may include typical reactions to diet changes and increased physical activity such as muscle soreness, fatigue, and possible nutritional deficiencies if not monitored properly.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Peer coach treatmentExperimental Treatment1 Intervention
Participants randomly assigned to this arm will receive a combination of in-person, group-based behavioral weight loss sessions plus individual, telephone contacts. Groups and phone calls will be facilitated by a peer coach interventionist. Similar to the self-directed condition, participants will receive written and pre-recorded intervention materials (i.e., DVDs, online videos). They will also have continued contact with their physician for routine medical care.
Group II: Self-directed treatmentActive Control1 Intervention
Participants randomly assigned to this arm will receive written and pre-recorded behavioral weight loss intervention materials (i.e., DVDs, online videos), and they will be instructed to work through the materials independently at their own pace. They will have continued physician contact as needed for routine medical care.
