The GATEKEEPER Study, a randomized controlled trial, assessed the impact of dietetic counseling combined with digital tools on hemodynamic markers in 954 Greek adults aged ≥55 with cardiometabolic risk. Over 3 months, all groups showed improvements, with the Platform + Devices group achieving a significant increase in physical activity (94.62 MET-min/week) and a notable reduction in pulse pressure (-3.90 mmHg) compared to Standard Care.
Key findings
- Waist circumference decreased by -6.29 cm in Standard Care, -4.92 cm in Platform, and -4.69 cm in Platform + Devices.
- Systolic blood pressure declined by -4.84 to -7.15 mmHg across all groups.
- The Platform + Devices group had a greater increase in physical activity of 94.62 MET-min/week.
- Weight loss was associated with lower odds of hypertension (OR 0.4) and greater likelihood of hypertension reversal (OR 3.6).
Why it matters
This study highlights the importance of dietary lifestyle interventions in managing cardiometabolic risk factors, particularly hypertension. While digital tools may enhance engagement, weight loss remains a critical factor in improving hemodynamic outcomes.
