The GATEKEEPER study evaluated the impact of dietetic counseling combined with digital tools on obesity-related outcomes in adults aged 55 and older at high risk for metabolic syndrome. This 3-month randomized controlled trial involved 984 participants and found that while waist circumference decreased in all groups, the addition of digital tools did not significantly enhance metabolic outcomes compared to standard care alone.
Key findings
- Waist circumference decreased by -6.29 cm in standard care, -4.92 cm in platform, and -4.69 cm in platform + devices groups.
- The platform group had a mean difference of -1.38 cm in waist circumference compared to standard care.
- Physical activity increased by +55.52 MET-min/week in the platform + devices group.
Why it matters
Understanding the effectiveness of dietetic counseling and digital tools can help clinicians design better interventions for older adults at risk for metabolic syndrome, potentially improving patient outcomes in obesity management.
