Diactive-1: Scaled-up Personalized mHealth Program for Youth With Type 1 Diabetes

Condition(s) studied

Investigational drug(s) / intervention(s)

Diactive-1: Participants will engage in a 12-week resistance exercise program with the goal of maintaining at least 3 sessions per week, with 3-6 exercises per session (≈13-33 minutes). Participants will be able to choose among three training formats, traditional resistance training, Tabata/high-intensity intervals, or circuit training, and may perform the sessions individually or in pairs, depending on preference and feasibility at the center. The training intervention will comprise 3-4 sets of 6-12 repetitions and will consist of a combination of exercises for the upper body, lower body, and core, using primarily the participants' own body weight. The load and intensity of the exercise will be adjusted according to the number of repetitions and the difficulty/progression of the selected exercises. A mobile application (Diactive-1) will be used to deliver, monitor, and record the sessions.

Study summary

The Diactive-1 project aims to establish the Diactive-1 mobile application as a clinical tool for managing type 1 diabetes in children and adolescents in several hospitals from Spain. The successful implementation of the app in new healthcare centers nationwide represents a key step toward the development of a comprehensive and scalable program. This approach seeks not only to optimize current patient care but also to democratize access to an innovative, evidence-based intervention that supports daily diabetes management.

In this new phase, the project will integrate the application into routine clinical care for patients with type 1 diabetes through the use of a simple handgrip strength measurement. A dedicated web platform (www.diactive.es) is being developed to allow clinicians to enter basic patient data, including handgrip strength, sex, and email address. Based on this information, the system will automatically generate a personalized download link for the Diactive-1 app, accompanied by tailored guidance and an initial fitness level classification (low, medium, or high) according to European reference values.

This process will define each user's baseline fitness level and facilitate the use of Diactive-1 as an integrated and individualized disease management tool. The ultimate goal is to strengthen clinical decision-making, improve patient engagement, and extend the benefits of digital health to a broader pediatric population living with type 1 diabetes.
