Establishing an optimal diagnostic criterion for respiratory sarcopenia using peak expiratory flow rate

Background The skeletal muscle changes as aging progresses, causing sarcopenia in the older adult population, which affects the respiratory muscles’ mass, strength, and function. The optimal cut-off point of peak expiratory flow rate (PEFR) for respiratory sarcopenia (RS) diagnosis in accordance wit...

Description
Summary:Background The skeletal muscle changes as aging progresses, causing sarcopenia in the older adult population, which affects the respiratory muscles’ mass, strength, and function. The optimal cut-off point of peak expiratory flow rate (PEFR) for respiratory sarcopenia (RS) diagnosis in accordance with sarcopenia identification is needed. Aim To establish an optimal cut-off point of PEFR for RS diagnosis in community-dwelling Asian older women. Methods Sarcopenia diagnostic indicators were evaluated according to the Asian Working Group for Sarcopenia 2019 (AWGS) criteria. The respiratory parameters composed of respiratory muscle strength and respiratory function were evaluated by assessing maximal inspiratory pressure (MIP), percent predicted forced vital capacity (Pred FVC), and PEFR. Results A total of 325 community-dwelling older women were included in this study. PEFR was negatively associated with RS (OR: 0.440; 95% CI: 0.344–0.564). The area under the curve (AUC) of PEFR was 0.772 ( p
