Abstract

Introduction: With a rapidly ageing population, sarcopenic obesity, defined as decreased muscle mass and function combined with increased body fat, is a complex health problem. Although sarcopenic obesity contributes to a decline in physical function and exacerbates frailty in older adults, evidence from clinical trials about the effect of exercise and nutrition on this complex syndrome in Chinese older adults is lacking.

Methods And Analysis: We devised a study protocol for a single-blind randomised controlled trial. Sarcopenia is described as age-related decline in muscle mass plus low muscle strength and/or low physical performance. Obesity is defined as a percentage of body fat above the 60th centile. Ninety-two eligible participants will be randomly assigned to a control group, nutrition group, exercise group and nutrition plus exercise group to receive an 8-week intervention and 12-week follow-up. The primary outcomes will be the change in short physical performance battery scores, grip strength and 6 m usual gait speed. The secondary outcomes will include basic activities of daily living scores, instrumental activity daily living scores, body composition and body anthropometric indexes. For all main analyses, the principle of intention-to-treat will be used.

Ethics And Dissemination: This study was approved by the medical ethics committee of Zhejiang Hospital on 25 November 2015. The study will present data targeting the clinical effects of nutrition and exercise on physical function and body composition in a Chinese older population with sarcopenic obesity. The results will help to provide important clinical evidence of the role of complex non-pharmaceutical interventions for sarcopenic obese older people. The findings of this study will be submitted to peer-reviewed medical journals for publication and presented at relevant academic conferences.
