Effect of Continuous Wearable Biometric Monitoring on Weight Loss and Metabolic Outcomes in Adults Undergoing Obesity Treatment: A Sensor-Mediated Adaptive Randomized Controlled Trial in Bariatric and Metabolic Intervention (SMART-BMI)
Jeff Reeves
Summary
The goal of this clinical trial is to learn if a smart ring that tracks health signals can help adults lose weight and improve their health during obesity treatment. The study includes adults who are having weight-loss surgery or starting weight-loss medication. The Oura Ring tracks signals like sleep, heart rate, and activity. In this study, the care team can see this information and use it to guide each person's care. The main questions it aims to answer are: Do people lose more weight when their care team uses the ring's information? Does using the ring's information improve health measures like blood sugar and blood pressure? The study has two parts. In the first part, everyone wears the ring while the study team makes sure the ring's information can be collected and used. In the second part, the study places participants into one of two groups by chance, like flipping a coin. One group's care team uses the ring's information. The other group's care team does not. Researchers will compare the two groups to see if the ring's information helps. Participants will: Wear the Oura Ring during the study Go to their regular clinic visits Answer survey questions about their health and quality of life
Description
This study addresses a specific gap in the evidence for consumer wearable devices in obesity care. Prior trials that supplied wearable devices without integrating the resulting data into clinical decision-making have generally not improved weight outcomes. This trial is therefore designed to test not the device in isolation, but whether care teams acting on continuous biometric data achieve better outcomes than standard care. The trial uses a two-phase adaptive design at a single academic medical center. Two treatment cohorts are enrolled in parallel throughout: adults undergoing metabolic an…
