Sharing Digital Self-Monitoring Data With Others to Enhance Long-Term Weight Loss
Sharing Digital Self-Monitoring Data With Others to Enhance Long-Term Weight Loss: A Randomized Trial Using a Factorial Design
Source: ClinicalTrials.gov · Last updated 7 Oct 2026
Brief summary (registry, in English)
Adults attempting weight loss through lifestyle modification (LM) typically find maintenance of behavior change difficult. Outcomes might be improved if participants are provided with sustained sources of accountability and support and ongoing opportunities to reflect with others on goal progress. This study proposes that sharing digital data with other parties has the potential to improve long-term weight loss. The proposed study will enroll adults ("index participants") (N = 321) with overweight/obesity in a 24-month LM program and instruct them to use digital tools for self-monitoring of weight, physical activity, and eating on a daily basis.
