Sarcopenia, a common syndrome in older individuals, is characterized by a progressive loss of muscle mass and muscle strength. Although data exist on the prevalence of sarcopenia in community-dwelling older individuals and nursing home residents, there has been no systematic research in hospitalized older patients according to newly developed criteria.
Cross-sectional study design.
Acute geriatric ward of a general hospital.
Geriatric inpatients.
Hand grip strength was measured with the Jamar dynamometer, skeletal muscle index was calculated from raw data obtained from the bioelectrical impedance analysis, and physical function was assessed with the Short Physical Performance Battery. Sarcopenia was defined according to the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP).
This study involved 198 patients from a geriatric acute ward. Mean age was 82.8 ± 5.9 years and 70.2% (n = 139) of the study participants were women. Thirteen patients (6.6%) were defined as sarcopenic and 37 (18.7%) were defined as severely sarcopenic. In a group comparison, patients with sarcopenia had a poorer nutritional status. In a binary logistic regression analysis, only body mass index was associated with sarcopenia, whereas gender, age, length of stay, cognitive function, and self-care capacity were not.
The prevalence of sarcopenia in geriatric hospitalized patients is high and does not differ from those of other older individuals. Nutritional status is associated with sarcopenia. The predictive value of sarcopenia regarding outcome for older individuals still requires evaluation.
肌少症是一种常见于老年人的综合征，其特征是肌肉质量和肌肉力量逐渐丧失。虽然社区居住的老年人和养老院居民的肌少症患病率数据已经存在，但根据新制定的标准，对住院老年人患者还没有进行系统的研究。
横断面研究设计。
一家综合医院的急性老年病房。
老年住院患者。
使用 Jamar 握力计测量握力，从生物电阻抗分析获得的原始数据中计算骨骼肌指数，并用简短体能状况测试评估身体功能。肌少症根据欧洲老年人肌少症工作组（EWGSOP）的标准定义。
这项研究涉及来自老年急性病房的 198 名患者。平均年龄为 82.8 ± 5.9 岁，70.2%（n = 139）的研究参与者为女性。13 名患者（6.6%）被定义为肌少症患者，37 名（18.7%）被定义为严重肌少症患者。在组间比较中，肌少症患者的营养状况较差。在二元逻辑回归分析中，只有体重指数与肌少症相关，而性别、年龄、住院时间、认知功能和自理能力则与肌少症无关。
老年住院患者的肌少症患病率较高，与其他老年人没有差异。营养状况与肌少症有关。肌少症对老年人预后的预测价值仍需评估。
