A new study powered by Centralive and published in Midwifery evaluates the SLIM intervention—a combination of a smart Oura ring, a food diary mobile app, a scale, motivational interviewing, and goal-setting—designed to support healthy lifestyle habits in pregnant women with overweight.
Key Takeaways
- Self-efficacy in eating and physical activity remained consistently high, with no significant changes over time.
- However, participants who stayed within recommended gestational weight gain were significantly more successful in postpartum weight loss.
- A long-term follow-up was essential to capture meaningful behavioral trends and outcomes over time.
At Centralive, we help research teams run complex, longitudinal health interventions with real-time data collection, monitoring, and feedback—all from one connected platform.
By supporting every phase of digital health research, we make it easier to turn insights into impact.
