Cancer, Weight Loss
Conditions
Brief summary
This study tests evidence-based strategies for weight loss among overweight and obesity cancer survivors and family members in rural Alabama.
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).
Interventions
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)
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.
Participants receive quarterly newsletters containing generic cancer prevention messages and participate in community-wide cancer awareness educational sessions.
