相位角被认为是评估老年人营养状况的有用、无创且客观的指标。然而，还没有研究根据性别分析老年患者营养状况与相位角之间的关系。本研究的目的是阐明相位角与营养不良之间的关系，并根据性别计算老年住院患者营养不良与相位角的临界点。这项研究是一项回顾性横断面研究。参与者为康复单位的老年住院患者，从病历中收集住院1周内的数据。我们收集了人口统计、相位角和老年营养风险指数的数据。使用 InBody S10 测量相位角。为了确认相位角是否是预测营养不良的重要因素，我们进行了二元逻辑回归分析。此外，为了确定老年住院患者营养不良的分界点，我们使用了受试者工作特征（ROC）曲线。参与者包括 59 名男性（平均年龄 76.5 岁）和 101 名女性（平均年龄 78.8 岁）。统计分析结果显示，无论是男性还是女性住院患者，相位角都是与营养不良相关的重要因素。我们的研究结果表明，男性患者的分界点为 4.03 度（敏感性为 87.0%，特异性为 75.9%），女性患者的分界点为 3.65 度（敏感性为 78.6%，特异性为 60.5%），可用于预测营养不良。这项研究的结果表明，相位角可作为预测老年住院患者营养状况的指标。
Phase angle has been suggested as a useful, noninvasive, and objective index to evaluate the nutritional status of older people. However, there are no studies analyzing the relationship between nutritional status and phase angle in older patients, according to sex. The aim of this study was to clarify the relationship between phase angle and malnutrition, and to calculate cut-off points of malnutrition with phase angle in older inpatients, according to sex. This study was a retrospective cross-sectional study. Participants were older inpatients of a rehabilitation unit, and data within 1 week of hospitalization were collected from the medical records. We collected data of demographics, phase angle, and the Geriatric Nutritional Risk Index. Phase angle was measured with InBody S10. To confirm whether phase angle is an important factor in predicting malnutrition, we conducted binary logistic regression analysis. In addition, to determine the cut-off points of malnutrition in older inpatients, we used the receiver operator characteristic (ROC) curve. Participants included 59 men (mean age 76.5 years) and 101 women (mean age 78.8 years). As a result of statistical analysis, phase angle was an important factor related to malnutrition in both male and female inpatients. Our findings showed that cut-off points of 4.03 degrees (sensitivity; 87.0%, specificity; 75.9%) in male patients and 3.65 degrees (sensitivity; 78.6%, specificity; 60.5%) in female patients could be used to predict malnutrition. The results of this study suggest that phase angle may be useful as an indicator to predict the nutritional status of older inpatients.
