VA|PREVENTION: Randomized Controlled Trial of a Person-Centred Digital Intervention to Prevent Diabetes in High-Risk Adults
Sponsor:

Egas Moniz - Higher Education Cooperative, CRL

Brief Summary:

The goal of this clinical trial is to help prevent the development of type 2 diabetes (T2D) in adults who are at risk. The study will test a digital intervention called VA\|PREVENTION, a web application designed to support and promote healthy behaviour changes known has T2D risk factors, such as physical activity, diet, and sedentary behaviuor. The main questions this study will explore are:• Is the VA\|PREVENTION web app, which includes a virtual human coach, effective in preventing type 2 diabetes?• Can the VA\|PREVENTION web app be successfully implemented in real-world settings?• Is the VA\|PREVENTION web app cost-effective?• Is it safe for participants to use?To answer these questions, the study team will compare the VA\|PREVENTION web app to an openly available guidebook that provides standard information about preventing type 2 diabetes.Participants will complete the following activities: * Participants will be randomly assigned to one of two groups: one group will use the VA\|PREVENTION app, while the other group will have access to an openly accessible guidebook on T2D prevention. * Participants will be in the study for 10 months. * Participants will be assessed at the start of the study (baseline), and again at 4 months and 10 months. * Assessments will include body measurements (such as weight, height, and waist circumference), physical activity levels, and responses to questionnaires.

Detailed Description:

T2D risk adults will be invited by nurses and community pharmacists, leveraging their trusted roles within the healthcare system. Recruitment activities will prioritize fair treatment and respect for informed consent. Only participants fully capable of understanding the informed consent terms will be included in the study. Potential participants will receive detailed information about the study's purpose, procedures, potential risks, and benefits. After providing time for questions and discussion, written informed consent will be obtained. Following consent, participants will undergo screening to confirm eligibility according to predefined inclusion and exclusion criteria. Those meeting all eligibility criteria will proceed to the baseline visit (T0), during which initial assessments will be conducted. After the baseline assessment, participants will be randomized into one of the study groups. Following randomization, the assigned intervention will be initiated, with subsequent visits scheduled at 4 months (T1) and 10 months (T2) for data collection.Upon obtaining informed consent, participants will undergo screening to verify eligibility according to predefined inclusion and exclusion criteria. Those who meet all criteria will proceed to the baseline visit (T0), where initial assessments will be conducted. Following this, participants will be randomly assigned to one of the study groups. The assigned intervention will then be initiated, with subsequent visits scheduled at 4 months (T1) and 10 months (T2) for data collection. At these timepoints, waist circumference, the primary endpoint, as well as data on anthropometric measurements (heigh and weight), diabetes risk (FINDRISC score), dietary adherence (through MEDAS questionnaire), physical activity (through accelerometry measurements), and health resources utilization will be collected.
