Brief Summary:
The purpose of this study is to examine whether a primary care weight management intervention delivered by peer coaches produces greater weight loss than a self-directed program without peer coach support.

Arm Intervention/treatment
Active Comparator: Self-directed treatment
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.
Behavioral: weight loss intervention - self directed
Experimental: Peer coach treatment
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.
Behavioral: weight loss intervention - peer coach

Primary Outcome Measures :
  1. body weight [ Time Frame: 6, 12, and 18 months ]
    change in body weight (kg) from baseline to follow-up assessments

Secondary Outcome Measures :
  1. physical activity [ Time Frame: 6, 12, and 18 months ]
    Self-reported physical activity assessed via the Paffenbarger Physical Activity Questionnaire (PPAQ).

  2. treatment adherence [ Time Frame: 6, 12, and 18 months ]
    Treatment adherence will be assessed by the number of treatment sessions and phone calls completed.

  3. treatment burden [ Time Frame: 6, 12, and 18 months ]
    Behavioral burden of treatment will be assessed with self-report questionnaires including items about the perceived burden of behavioral targets such as self-monitoring, dietary changes, maintaining physical activity, and the impact of treatment on social relationships.

  4. treatment satisfaction [ Time Frame: 6, 12, and 18 months ]
    Participants will complete self-report items assessing their attitudes and satisfaction regarding the weight loss intervention and weight loss achieved.

  5. side effects [ Time Frame: 6, 12, and 18 months ]
    Symptom checklist including minor (e.g., constipation, dry mouth) and more severe events (e.g., cardiovascular events) will be administered to assess potential adverse side effects associated with treatment.

  6. quality of life [ Time Frame: 6, 12, and 18 months ]
    Quality of life will be assessed through the validated Short-Form 12 (SF-12), which provides measures of health-related quality of life for physical and mental health.

  7. physical and social functioning [ Time Frame: 6, 12, and 18 months ]
    Items from the Patient Reported Outcome Measurement Information System (PROMIS) will be administered, including the 8-item short forms for physical and social functioning.

  8. mood [ Time Frame: 6, 12, and 18 months ]
    The Patient Health Questionnaire-8 (PHQ-8), a validated self-report measure of depressive symptoms experienced over the past two weeks, will be administered.

  9. healthcare utilization [ Time Frame: 6, 12, and 18 months ]
    Self-reported utilization of health care services (hospitalizations, ER/physician office visits, prescription drugs, etc.) and out-of-pocket costs will be collected.

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description: With the documented permission of the IRB, the PI may develop a transportable de-identified database, codebook, and mechanism by which data can be shared with qualified investigators. Interested investigators will be asked to complete a standardized request form stating the specific aims of the analyses, the analytic plan, available resources for completing the proposed project, proposed timeline, and goals (i.e., manuscripts, presentations, and/or grant applications). The PI and research team will review these requests to determine whether the proposed analyses constitute an innovative and significant exploration of the data, whether the proposed team has sufficient resources to complete the request, and whether data will be adequately protected and managed. If any of these issues are problematic, the PI and research team will attempt to negotiate a fair resolution with the interested investigators and NIH program staff.
