NCT01850550

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Percent Change in Weight

    We will assess our participants to evaluate the percent change in weight over the 12 week period of the study using a scale.

    12 weeks after initial consent

Secondary Outcomes (4)

  • BMI

    12 weeks after initial consent

  • Blood Pressure

    12 weeks after initial consent

  • Physical Activity

    12 weeks after initial consent

  • Dietary Intake

    12 weeks after initial consent

Study Arms (2)

Control

NO INTERVENTION

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.

Weight Loss Groups

EXPERIMENTAL

Participants in this arm will receive peer-led facilitation within groups using an adaptation of the Diabetes Prevention Program.

Behavioral: Weight loss Groups

Interventions

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.
