The Asia-Oceania consensus: Definitions and diagnostic criteria for sarcopenic obesity

The aim of this study was to develop consensus definitions and diagnostic criteria for sarcopenic obesity tailored to Asia-Oceania populations, a condition characterized by reduced skeletal muscle mass and function with excess adipose tissue.

Experts from various fields formed a working group under the Asia-Oceania Association for the Study of Obesity (AOASO) and the International Association of Gerontology and Geriatrics Asia/Oceania Region (IAGG-AOR). The group convened four meetings, employing the Delphi technique to achieve consensus on diagnostic criteria and management strategies for sarcopenic obesity.

The consensus defines sarcopenic obesity with a 3-step algorithm, including screening, diagnosis, and intervention. The screening criteria included BMI and waist circumference for obesity and calf circumference, the SARC-F, and the Finger Ring test for sarcopenia. The diagnostic criteria for sarcopenia include assessments of muscle mass (using dual-energy X-ray absorptiometry or bioelectrical impedance analysis), muscle strength (handgrip strength), and physical performance (gait speed, Short Physical Performance Battery, or the 5-Times Sit-to-Stand Test). Central obesity is the main concern for the diagnosis of obesity. The working group recommends a combination of dietary consultations, increased physical activity, resistance training, and the potential use of oral nutritional supplements and medications for managing sarcopenic obesity. The primary objective is to increase skeletal muscle mass and reduce adipose tissue mass.

The established criteria facilitate early recognition and management of sarcopenic obesity, highlighting the need for tailored interventions. Future research should focus on the long-term outcomes of these interventions and the development of pharmacological treatments.
