Body composition (BC) assessment can supply accurate information for in-hospital nutritional evaluation. The aim of this study was to explore in the literature how the studies assessed BC, for what purpose, and investigate the role of BC findings in COVID-19 hospitalized patients' outcomes.
A scoping review was conducted according to the methodology available on the Joanna Briggs Institute website. We used the PCC acronym for the systematic search (population: adults with COVID-19, concept: assessment of BC, context: hospital setting) and performed it on PubMed, Scopus, and the Web of Science on 16 September 2022. Eligibility criteria consisted of the utilization of BC assessment tools in COVID-19 patients. Studies in which BC was solely measured with anthropometry (perimeters and skinfolds) were excluded. No language restriction was applied.
Fifty-five studies were eligible for the review. Out of the 55 studies, 36 used computed tomography (CT), 13 used bioelectrical impedance (BIA), and 6 used ultrasound (US). No studies with D3-creatinine, 24 h urine excretion, dual-energy X-ray absorptiometry, or magnetic resonance were retrieved. BC was mainly assessed to test associations with adverse outcomes such as disease severity and mortality.
Studies assessing BC in hospitalized patients with COVID-19 used mainly CT and BIA and associated the parameters with severity and mortality. There is little evidence of BC being assessed by other methods, as well as studies on BC changes during hospitalization.
身体成分（BC）评估可为住院患者的营养评估提供准确信息。本研究的目的是在文献中探讨各项研究如何评估身体成分、评估目的是什么，并调查身体成分评估结果在新冠肺炎住院患者预后中的作用。
根据乔安娜·布里格斯研究所网站上提供的方法进行了一项范围综述。我们使用PCC首字母缩写进行系统检索（人群：新冠肺炎成年患者，概念：身体成分评估，背景：医院环境），并于2022年9月16日在PubMed、Scopus和科学网上进行了检索。纳入标准包括在新冠肺炎患者中使用身体成分评估工具。仅通过人体测量学（周长和皮褶厚度）测量身体成分的研究被排除。不设语言限制。
55项研究符合综述要求。在这55项研究中，36项使用了计算机断层扫描（CT），13项使用了生物电阻抗分析（BIA），6项使用了超声（US）。未检索到使用3-肌酐、24小时尿排泄、双能X线吸收法或磁共振成像的研究。身体成分主要用于评估与疾病严重程度和死亡率等不良后果的相关性。
评估新冠肺炎住院患者身体成分的研究主要使用CT和BIA，并将这些参数与疾病严重程度和死亡率相关联。几乎没有证据表明身体成分是通过其他方法评估的，也缺乏关于住院期间身体成分变化的研究。
