mHealth Intervention to Prevent Type 2 Diabetes Mellitus (Phase II Study)

The PREDIABETEXT project will involve five WorkPackages (WP). In WP1-4 we will develop and pilot-test the different components of the intervention (WP1 will develop the brief text messages targeted to patients; WP2 will adapt our existing technology system to deliver the messages; WP3 will develop an educational intervention targeted to Primary Healthcare workers, and; WP4 will pilot-test and optimise both interventions). In WP5 we will conduct a phase II, six-month, three-arm, cluster randomised, clinical trial with 42 primary care workers and 420 patients at risk of T2DM (HbA1c from 6% to 6.4% or fasting plasma glucose 110-125mg/dl, or both) registered in Primary Care centres from Mallorca. Patients will be allocated to a control (usual care) group, intervention A (patient messaging intervention), or intervention B (patient messaging intervention plus online education to their primary healthcare workers). The primary outcome will be HbA1c. Secondary outcomes will include additional clinical outcomes, and physiological, behavioural and psychological outcomes.
