Non-pharmacological treatment strategies for anthropometric, physical capacity and physiological indicators among sarcopenic obesity patients: a systematic review of rigorous randomized controlled trials

Age Ageing. 2024 Nov 28;53(12):afae278. doi: 10.1093/ageing/afae278.

Abstract

Objectives: To investigate the effects of non-pharmacological treatments on sarcopenic obesity (SO).

Methods: A search for randomized controlled trials (RCTs) on SO was conducted in PubMed, Web of Science, CINAHL, CENTRAL, SPORTDiscus, CNKI, Wanfang and VIP. A meta-analysis was conducted using random-effects models for MDs.

Results: The meta-analysis on 21 RCTs showed that exercise improved PBF (MD: -1.67%, p < .01, I2 = 35%), grip strength (MD: 2.2 kg, p = .03, I2 = 61%), GS (MD: 0.08 m/s, p = .02, I2 = 0%), TCR (MD: 2.22 repetitions, p < .01, I2 = 0%), TUG (MD: -1.48 s, p < .01, I2 = 61%), UE strength (MD: 1.88 kg/kg, p < .01, I2 = 0%) and LE strength (MD: 2.19 kg/kg, p < .01, I2 = 0%). Nutritional interventions improved grip strength (MD: 1.52 kg, p < .01, I2 = 0%). Combine interventions improved PBF (MD: -1.97%, p < .01, I2 = 38%), ASMM (MD: 0.4 kg, p < .01, I2 = 6%), grip strength (MD: 1.83 kg, p < .01, I2 = 38%) and GS (MD: 0.04 m/s, p < .01, I2 = 0%). Combined interventions were more effective than nutrition alone for reducing PBF (MD: -0.8%, p = .05, I2 = 0%).

Conclusion: The effects of exercise and nutrition interventions on SO are limited individually, especially regarding muscle mass, but their combination can yield optimal results. Additionally, physical therapy also demonstrated some potential.
