Remote Technology Reduces Waist Circumference in Rehabilitation

In a randomized mixed-methods trial published in J Med Internet Res (2026), 59 cardiac rehabilitees (mean age 60; 81% male) were assigned to conventional rehabilitation with or without added remote technology and followed for 12 months. The experimental group showed a greater waist circumference reduction of 2.5 cm at 0–6 months (P=.007), though no independent predictors emerged for 0–12 months. Qualitative themes indicated goal-oriented monitoring in the technology group versus unstable weight management in controls.
