Digital intervention promoting physical activity among obese people (DIPPAO) randomised controlled trial: study...

Area of Science:

• Obesity and diabetes research
• Digital health interventions
• Behavioral science in health

Background:

• Physical inactivity and sedentary behaviors are key factors in obesity and type 2 diabetes mellitus (T2DM).
• Current physical activity (PA) programs often fail to sustain patient engagement long-term.
• Novel approaches are needed to improve adherence to PA interventions.

Purpose of the Study:

• To evaluate the effectiveness of a gamified, group-based digital intervention (Kiplin) for increasing physical activity in obese patients with T2DM.
• To compare the Kiplin intervention against a standard supervised PA program.
• To explore psychological mediators and conduct a cost-utility analysis.

Main Methods:

• A two-arm parallel randomized controlled trial (RCT) involving 50 patients.
• A 3-month intervention period with a 6-month follow-up.
• Primary outcome: change in daily step count; secondary outcomes: accelerometer data, self-reported PA, body composition, physical capacities, psychological mediators, and cost-utility.

Main Results:

• Data collection is ongoing; primary outcome is daily step count change.
• Exploration of psychological mediators like motivation and social identity.
• Cost-utility analysis to compare economic efficiency.

Conclusions:

• The Kiplin intervention aims to provide a sustainable and engaging solution for increasing physical activity in obese patients with T2DM.
• Findings will inform app development and clinical practice.
• Results will be disseminated through publications and conferences.
