Detailed Description
This is a 3-arm cluster randomized controlled study that compares a trained lay provided weight loss program vs. the same program plus community-based weight management strategies vs. general cancer prevention education on weight loss and other clinical outcomes (primary outcomes) and healthy behaviors, and psychosocial functioning (secondary outcomes).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Weight Loss Only Group-based behavioral weight loss intervention designed to reach clinically significant weight loss (~5-10% of baseline weight). |
Behavioral: Weight Loss Only
24- month weight loss program (year 1: weekly in person meetings for 6 months, followed by 2 meetings per month for 3 months, then monthly for 3 months; year 2: monthly phone calls)
|
| Experimental: Weight Loss Plus Group-based behavioral weight loss intervention designed to reach clinically significant weight loss (~5-10% of baseline weight) plus community-level strategies to support healthy weight. Strategies are based on CDC's recommended community strategies and are developed by local contractors. They include expanded farmers markets/gardens, improvement to walking trails, etc. |
Behavioral: Weight Loss Plus
Participants will attend in-person weekly sessions (about 1.5 hours each) for 6 months and then twice a month for 3 months and monthly for 3 months. Sessions focus on behavioral techniques supporting healthy diet (including calorie restriction for weight loss) and achieving recommended amounts of physical activity per week. During 1-year weight loss maintenance, participants receive monthly motivational phone calls.
|
| Active Comparator: Control Educational materials and optional participation in community-wide cancer awareness activities. |
Behavioral: Control
Participants receive quarterly newsletters containing generic cancer prevention messages and participate in community-wide cancer awareness educational sessions.
