Sacropenic Obesity

Background: Sarcopenic obesity (SO) affects 10% of older adults increased to 23% of those 75+, raising health risks and health cost. Objectives: We will evaluate the effects of the EatWelLog App-based intervention on SO status (primary outcome), and nutritional and exercise parameters (secondary outcomes) by enhancing self-management and sustaining diet adherence among the m-Health group using the App versus the control group. Following verification of the intervention's effectiveness, we will analyse its cost-effectiveness. Design and subjects: Randomized controlled trial with 212 older people with SO. Interventions: The m-Health group will receive an 8-week supervised nutrition and exercise programme, incorporating the EatWelLog App for dietary management during and after the supervised programme. The control group will receive the same programme without the App. Main outcome measures and analysis: The primary outcome is SO status evaluated using handgrip strength, muscle mass, body fat mass, and physical performance. Secondary outcomes include nutritional status, quality of life and exercise adherence. The App intervention's costeffectiveness will be analysed. Expected results: The m-Health group should demonstrate greater, more sustained improvements in SO and secondary outcomes compared to the control group at Week 8, and at the 3-, 6-, 9-, and 12-month follow-ups. Clinical significance: The EatWelLog App could provide customized support, enhance dietary adherence, and improve long-term outcomes, offering a novel, economical approach to SO management.
