- Abstract
Objectives: 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. Design: Cross-sectional study. Location: Macapá, Brazil. Participants: community-dwelling elderly ≥ 60 years old (n=383), both sexes. Measures: 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. Results: 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). Conclusions: 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.
