This pilot 2-arm randomized controlled trial tested a 15-week telephone-based weight loss intervention in 40 rural Ohio residents with overweight or obesity.
This pilot 2-arm randomized controlled trial enrolled 40 rural Ohio residents with overweight or obesity (27 intervention, 13 active control) using 2:1 randomization. However, adherence to the intervention was only 48%, as only 13 of 27 participants attended at least 12 of 15 sessions, falling below the 75% pre-defined threshold. The sample was predominantly female and all participants were White, limiting generalizability. The COVID-19 pandemic presented recruitment and retention challenges, contributing to low adherence and a 31.7% no-show rate at baseline. Dropout remained under 20%, supporting feasibility for a future efficacy trial.
