Sarcopenic obesity, or the loss of muscle mass and function associated with excess adiposity, is a largely untreatable medical condition associated with diminished quality of life and increased risk of mortality. To date, it remains somewhat paradoxical and mechanistically undefined as to why a subset of adults with obesity develop muscular decline, an anabolic stimulus generally associated with retention of lean mass. Here, we review evidence surrounding the definition, etiology, and treatment of sarcopenic obesity with an emphasis on emerging regulatory nodes with therapeutic potential. We review the available clinical evidence largely focused on diet, lifestyle, and behavioral interventions to improve quality of life in patients with sarcopenic obesity. Based upon available evidence, relieving consequences of energy burden, such as oxidative stress, myosteatosis, and/or mitochondrial dysfunction, is a promising area for therapeutic development in the treatment and management of sarcopenic obesity.
肌肉减少性肥胖,或与过多脂肪相关的肌肉质量和功能丧失,是一种尚未得到充分治疗的医学病症,与生活质量下降和死亡率增加有关。迄今为止,为什么肥胖的成年人中有一部分会出现肌肉衰退,这在某种程度上仍然是矛盾的,而且其机制尚未确定,而肌肉衰退通常与瘦体重的保留有关。在这里,我们回顾了与肌肉减少性肥胖的定义、病因和治疗相关的证据,重点介绍了具有治疗潜力的新兴调节节点。我们主要回顾了现有的临床证据,这些证据主要集中在改善饮食、生活方式和行为干预方面,以提高肌肉减少性肥胖患者的生活质量。根据现有证据,缓解能量负担的后果,如氧化应激、肌内脂肪增多和/或线粒体功能障碍,是治疗和管理肌肉减少性肥胖的一个有前途的治疗开发领域。
