To compare the obtained and expected values of pulmonary function variables between sarcopenic and non-sarcopenic elderly; verify the association between the pulmonary function and the indicators and diagnosis of sarcopenia; and establish cut-off points for pulmonary function variables to predict sarcopenia.
Cross-sectional study.
Macapá, Brazil.
community-dwelling elderly ≥ 60 years old (n=383), both sexes.
Were evaluated according to variables of pulmonary function (spirometry) and sarcopenia, according to the EWGSOP consensus. The association between pulmonary function and sarcopenia was performed using logistic regression and cut-off points established from the ROC Curve.
The prevalence of sarcopenia was 12.53% (n = 48). Sarcopenic individuals had significantly lower mean values for FVC, FEV1, FEF25-75% and PEF than non-sarcopenic. After adjustment, spirometric variables were inversely associated with sarcopenia (the increase by one unit of liter in FVC, FEV1 and FEF25-75% decreased the probability of sarcopenia by 59%, 67% and 39%, respectively), and the majority of these variables with the muscular strength indicator. Cut-off points, for elderly men and women, were discriminant criteria for the presence of sarcopenia: FVC (≤2.52 L and ≤1.82 L), FEV1 (≤2.1 L and ≤1.39 L), PEF (≤3.45 L/s and ≤2.93 L/s) and FEF5-75% (≤1.97 L/s and ≤1.74 L/s).
There was loss of pulmonary function in sarcopenic elderly patients and an inverse association with the diagnosis of sarcopenia and its indicators. Cut-off points of pulmonary function variables can be used as a useful tool to discriminate sarcopenia.
比较肌少症和非肌少症老年人的肺功能变量的实测值和预期值；验证肺功能与肌少症指标和诊断之间的关系；并建立肺功能变量的截断值来预测肌少症。
横断面研究。
巴西马卡帕。
≥ 60 岁的社区居住老年人（n=383），男女不限。
根据肺功能（肺活量测定法）和肌少症的变量进行评估，符合 EWGSOP 共识。使用逻辑回归和 ROC 曲线建立截断值来评估肺功能与肌少症之间的关系。
肌少症的患病率为 12.53%（n=48）。与非肌少症者相比，肌少症患者的 FVC、FEV1、FEF25-75%和 PEF 的平均值明显较低。调整后，肺活量测定变量与肌少症呈负相关（FVC、FEV1 和 FEF25-75%每增加一个单位，肌少症的可能性分别降低 59%、67%和 39%），且大多数与肌肉力量指标相关。对于老年男性和女性，截断值是存在肌少症的判别标准：FVC（≤2.52 L 和≤1.82 L）、FEV1（≤2.1 L 和≤1.39 L）、PEF（≤3.45 L/s 和≤2.93 L/s）和 FEF5-75%（≤1.97 L/s 和≤1.74 L/s）。
肌少症老年患者存在肺功能下降，与肌少症及其指标的诊断呈负相关。肺功能变量的截断值可作为鉴别肌少症的有用工具。
