Sarcopenia is a geriatric syndrome, which affects the functional status and mobility of individuals.
To identify the prevalence of sarcopenia and undernutrition, and to assess the association between sarcopenia and mobility, and sarcopenia and basic activities of daily living (ADL) in a group of elderly women.
A cross-sectional study was performed in patients attending a geriatric service at a government hospital in Mexico City. Sarcopenia was identified applying Baumgartner's equation by obtaining skeletal muscle mass index (SMI) and undernutrition was diagnosed using mini-nutritional assessment instrument (MNA). The SENECA questionnaire and Katz index were used to evaluate mobility and ADL, respectively.
lineal regression models were constructed fitting SMI as a dependent variable and SENECA, and ADL scores as independent variables, adjusted for age.
90 women with a mean age of 78.2 (± 6.8) were studied. Undernutrition was identified in 15.5% of the patients. The prevalence of sarcopenia was 41.1%. Patients with sarcopenia presented a high prevalence of undernutrition (p < 0.001). Sarcopenia was associated with difficulty in climbing stairs (OR = 2.63, p = 0.03), adjusted for age. The mobility score was associated with sarcopenia, in the group without sarcopenia the mean score was 16.3, and with sarcopenia it was 18.3, (p = 0.04). Regarding ADL, 64.9% of the patients with intermediate independence and dependence had sarcopenia, while 35.1% with total independence presented sarcopenia (p < 0.001).
The elder women with sarcopenia had a higher prevalence of undernutrition. Sarcopenia was associated with difficulties in mobility, particularly difficulties in climbing stairs.
肌肉减少症是一种老年综合征，会影响个体的功能状态和活动能力。
确定一组老年女性中肌肉减少症和营养不良的患病率，并评估肌肉减少症与活动能力之间的关联，以及肌肉减少症与日常生活基本活动（ADL）之间的关联。
在墨西哥城一家政府医院的老年科就诊患者中进行了一项横断面研究。通过获取骨骼肌质量指数（SMI）应用鲍姆加特纳方程来确定肌肉减少症，并使用微型营养评定量表（MNA）诊断营养不良。分别使用SENECA问卷和Katz指数评估活动能力和ADL。
构建线性回归模型，将SMI作为因变量，SENECA和ADL评分作为自变量，并根据年龄进行调整。
研究了90名平均年龄为78.2（±6.8）岁的女性。15.5%的患者被确定为营养不良。肌肉减少症的患病率为41.1%。肌肉减少症患者中营养不良的患病率较高（p<0.001）。经年龄调整后，肌肉减少症与爬楼梯困难相关（OR=2.63，p=0.03）。在无肌肉减少症组中活动能力评分的平均值为16.3，有肌肉减少症组为18.3，活动能力评分与肌肉减少症相关（p=0.04）。关于ADL，中度独立和依赖的患者中有64.9%患有肌肉减少症，而完全独立的患者中有35.1%患有肌肉减少症（p<0.001）。
患有肌肉减少症的老年女性营养不良的患病率较高。肌肉减少症与活动能力困难相关，尤其是爬楼梯困难。
