정황
상세 설명
Rationale: An estimated 400,000 individuals in the Netherlands are living with undiagnosed type 2 diabetes (T2D), in addition to 1.1 million diagnosed cases. Unhealthy lifestyle behaviours are a major contributing factor. Intensive lifestyle interventions and Continuous Glucose Monitoring (CGM) have demonstrated effectiveness in improving health behaviour and glycaemic control. Digital health technologies, including personalised digital interventions and virtual coaching enable continuous, scalable and context-specific support, thereby facilitating sustained behaviour change and improved self-management. Remote lifestyle interventions are therefore promising and may enhance self-management and glycaemic control, reduce medicine use and delay the development of comorbidities and diabetes-related complications. This study evaluates a remote, personalised lifestyle program combining online group sessions, peer support, CGM use, and a virtual AI lifestyle coach for individuals living with T2D.
Objective: The objective of this study is to evaluate the added value of CGM, biofeedback and a virtual AI lifestyle coach providing personalised, data-driven support within a first prototype of a remote lifestyle intervention for adults with T2D. Specifically, this pilot randomized controlled trial aims to assess the incremental effects of CGM, biofeedback and AI supported personalised coaching, informed by glucose data, demographics, behaviour, goals and preferences on health behaviours and glycaemic control over a 12-month period with two follow-up measurements.
Study design: This three-arm parallel-group randomized controlled trial includes:
- A lifestyle program consisting of online group sessions and a peer support community.
- The same lifestyle program supplemented with a virtual AI lifestyle coach.
- The AI-supported program with four times CGM use.
Study population: Adults (n=160) with T2D (HbA1c ≥53 mmol/mol) without glucose lowering medication (except Metformin), both men and women from all ethnic backgrounds.
Intervention: Participants complete an online baseline questionnaire and a brief in-app intake prior to randomization. All participants attend online group sessions and may engage with peers via the online community. The AI lifestyle coach uses the baseline data to have personalised coaching conversations with the participant throughout the intervention. In the third arm, real-time CGM data are additionally integrated into the AI-driven personalisation process.
Main study parameters/endpoints: The primary outcome is change in HbA1c from baseline to 12 months. Secondary outcomes include changes in physiological (e.g. body weight), clinical (e.g. time in range), behavioural (e.g. dietary intake), and psychological (e.g. quality of life) outcomes.

활성 비교기: Arm 1
Lifestyle program (control group)
|
Participants are asked to work on improving their lifestyle.
They have access to an online community throughout the study, where they can get in touch with other participants within their research-arm.
Participants are also asked to attend twelve online group sessions, during which a lifestyle coach will explain more about nutrition, physical activity, sleep, stress, social aspects, challenges and setbacks, and long-term maintenance.

|
실험적: Arm 2
Lifestyle program + coach
|
Idem to arm one, supplemented with a virtual AI lifestyle coach.
The AI lifestyle coach can process all the information about the participant that was provided at baseline.
This information is compiled into a participant profile, which the AI lifestyle coach uses to initiate personalised conversations with the participant.
During these conversations, the AI lifestyle coach supports the participant through a structured coaching cycle of three phases: preparation (reflecting on what matters and co-creating a personalised plan), coaching (day-to-day support to work on the plan), and evaluation (reviewing progress and adjusting or renewing the plan).
The coach draws on an evidence-based knowledge base of lifestyle interventions to recommend appropriate, evidence-informed actions.
The use of the AI lifestyle coach is an additional topic to the online group sessions.
|
|
실험적: Arm 3
Lifestyle program + coach + CGM
|
Idem to arm two, but participants are also asked to wear an CGM four times for two consecutive weeks.
The glucose values information collected by the CGM is used by the AI lifestyle coach to make conversations with the participant even more personalized.
The use of CGMs is an additional topic to the online group sessions.
