Thus, in this study, we aimed to compare the concordance in diagnosing respiratory sarcopenia based on the maximal respiratory pressure (MRP) and peak expiratory flow rate (PEFR), which are specific indicators of respiratory\u2010muscle strength, in a community\u2010dwelling older adult population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In the Otassha Study conducted in 2023, 499 community\u2010dwelling adults aged &gt;65\u2009years in Itabashi Ward (184 men and 315 women) were evaluated for MRP, PEFR, walking speed, grip strength, and appendicular skeletal muscle mass (ASM). We determined two respiratory\u2010sarcopenia models using low skeletal muscle mass and low MRP\/PEFR (both &lt;80% for predicted values). Pearson correlation coefficients were used to compare each measurement; the agreement between respiratory sarcopenia diagnosed using low MRP and PEFR was evaluated using kappa coefficients (\u03ba).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>PEFR was correlated with MRP (maximal expiratory pressure: <jats:italic>r<\/jats:italic>\u2009=\u20090.415; maximal inspiratory pressure: <jats:italic>r<\/jats:italic>\u2009=\u20090.380; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01, respectively). A moderate level of agreement was found between respiratory sarcopenia diagnosed using MRP and that diagnosed using PEFR (\u03ba\u2009=\u20090.597, match rate\u2009=\u200987.2%), suggesting a fair consistency level between the methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Although PEFR had a moderate correlation with MRP, the concordance of respiratory sarcopenia diagnosed using the two methods was moderate, suggesting that the two approaches are partially interchangeable and are complementary.
