·clinical-trialsA completed randomised controlled trial from Charles University has evaluated whether a just-in-time adaptive mHealth intervention — delivered via general practice using the HealthReact platform and Fitbit wearables — can increase daily step counts in patients with prediabetes or type 2 diabetes. With 343 participants across 20 Czech general practices, the trial offers a scalable model of technology-enabled physical activity support that primary care clinicians worldwide should watch closely as results emerge.
