Abstract

Bioelectrical impedance analysis (BIA) is a non-invasive method used to assess body composition and estimate metabolic age (MA). However, the clinical significance of BIA-estimated MA remains poorly understood. We explored the associations of MA with chronological age (CA), multimorbidity, and physical frailty (PF) in falls clinic attendees. Participants aged ≥50 years were assessed for multimorbidity using the Cumulative Illness Rating Scale-Geriatric, PF using the SHARE Frailty Instrument for Primary Care, and underwent BIA. Among 107 participants (mean age 69.8 years, 57% women), MA showed a moderate correlation with CA (r=0.62, p<0.001). On bivariate analysis, participants with MA>CA were younger, had higher multimorbidity, and were frailer compared to those with MA

生物阻抗-估计代谢年龄在跌倒诊所：与多病和身体虚弱的关系。

生物电阻抗分析（BIA）是一种用于评估身体成分和估计代谢年龄（MA）的非侵入性方法。然而，bia估计的MA的临床意义仍然知之甚少。我们探讨了MA与跌倒临床参与者的实足年龄（CA）、多病和身体虚弱（PF）的关系。年龄≥50岁的参与者使用累积疾病评定量表-老年性评估多病性，使用SHARE初级保健虚弱量表评估PF，并接受BIA。在107名参与者中（平均年龄69.8岁，57%为女性），MA与CA表现出中度相关性（r=0.62），与MA患者相比，pCA更年轻，有更高的多病性，并且更脆弱
