摘要

背景和目的：相位角（Phase angle，PhA）是生物电阻抗分析（BIA）的一个原始变量，是肌肉结构和质量的一项指标，可能在营养状况评估中发挥潜在作用。本系统性综述旨在评估中风患者的基线 PhA 及其在住院期间的变化；PhA 与患者临床特征、合并症、营养状况或肌肉疏松症以及临床结果的关系：根据 PRISMA 检查表，对截至 2024 年 6 月 14 日的电子数据库（PubMed、Scopus 和 Web of Science）进行了系统研究。采用 PECOS 策略，"P"（患者）= 脑卒中患者，"E"（暴露）= 最低 PhA 值，"C"（对比）= 与最大 PhA 值对比，"O"（结果）= 营养和临床结果，"S"（研究设计）= 所有研究类型。方法学质量采用观察性队列和横断面研究质量评估工具（NIH）进行评估：结果：18 篇论文符合纳入标准，偏倚风险较低。在中风患者中，有证据表明 PhA 与营养不良、肌肉疏松症和肌肉疏松性肥胖以及身体功能有关。此外，Phan值低的患者住院时间更长，炎症程度更高，尿路感染和医院获得性肺炎的发病率也更高：结论：部分论文虽然没有得出结论，但表明在急性和亚急性脑卒中患者中，PhA 与营养不良和身体功能差呈反比关系。PhA 可以作为健康状况和疾病进展的标志。PhA 可能有助于对营养状况进行更全面的评估，以用于诊断和实施治疗。

Bioelectrical impedance analysis (BIA) phase angle in stroke patients: A systematic review

Background and aims

Phase angle (PhA), a raw variable of bioelectrical impedance analysis (BIA), is an index of muscle structure and quality and might have a potential role in the evaluation of nutritional status.

The aim of this systematic review was to evaluate in stroke patients: baseline PhA and its changes during hospital stay; the association of PhA with clinical features of patients, comorbidities, nutritional status or sarcopenia, and clinical outcomes.

Methods

Systematic research on electronic databases (PubMed, Scopus, and Web of Science) up to June 14th, 2024 was performed according to PRISMA checklist.

Using PECOS strategy, “P” (patients) = stroke patients, “E” (exposure) = lowest PhA values, “C” (comparison) = versus greatest PhA values, “O” (outcome) = nutritional and clinical outcomes, and “S” (study design) = all study types.

Methodological quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies (NIH).

Results

Eighteen papers met the inclusion criteria, with a low risk of bias. In stroke patients, evidence suggests that PhA was associated with malnutrition, sarcopenia and sarcopenic obesity, as well as with physical function. In addition, patients with low PhA had a longer hospital stay, higher inflammatory status and higher incidence of urinary tract infections and hospital-acquired pneumonia.

Conclusions

Selected papers, although not conclusive, show that in acute and subacute stroke patients PhA was inversely associated with malnutrition and poor physical function. PhA could be a marker of health status and disease progression. PhA may be useful in a more comprehensive evaluation of nutritional status to be used for diagnosis and implementing therapy.
