Impact of Volunteer Peer-Led Intervention for Weight Control in Primary Care (KL2)
The specific objective of this research proposal is to determine the short-term efficacy of a primary care-based weight control intervention in which successful volunteer peers deliver a group-based program.
The purpose of the study is to conduct a pilot randomized controlled trial (RCT) of a successful volunteer peer-led weight control program compared to a control condition to determine intervention efficacy at 3 months. Six peer leaders from 2 primary care clinics will be recruited and trained to conduct the intervention. Overweight and obese patients (n=80) will be recruited (randomized by individual) to determine weight loss at 3 months (primary outcome). The program consists of 12 weekly weight loss sessions led by a successful volunteer peer leader using an adaptation of the Diabetes Prevention Program to help participants lose weight.
Study Overview
Detailed Description
The intervention will consist of 12 weekly one-hour weight loss sessions led by successful volunteer peers. The initial weight loss session will be conducted by the peer leaders with oversight by the PI. This session will serve to introduce the program and give an overview of program. The remaining sessions, conducted by co-peer leaders, will utilize an adaptation of the Diabetes Prevention Program. This adaptation allows for use in a group setting and facilitation by a lay individual.
Control Condition: Participants in the control condition will be given written information at the baseline visit from the NIH website "Aim for a Healthy Weight" to provide a basic understanding of weight loss and access to basic online resources. We expect that use of the website may result in some weight loss. However, similar information-only interventions have had a very small effect, which is accounted for in the sample size calculation.

Intervention / Treatment |
---|---|
NO_INTERVENTION: Control
Participants in the control condition will be given written information at the baseline visit from the NIH website "Aim for a Healthy Weight" to provide a basic understanding of weight loss and access to basic online resources, but will not participate in group weight loss sessions with peer leaders.

EXPERIMENTAL: Weight Loss Groups
Participants in this arm will receive peer-led facilitation within groups using an adaptation of the Diabetes Prevention Program.
|
The intervention will consist of 12 weekly one-hour weight loss sessions led by successful volunteer peers.
Participants are provided with a modified version of the Diabetes Prevention Program manual and are mentored by peer leaders at weight loss sessions.
