This study aimed to define CC cutoffs for detecting low muscle mass in older adults, using appendicular lean mass (ALM) from dual\u2010energy x\u2010ray absorptiometry (DXA) as the reference, stratified by sex and age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 254 adults \u226560 years of age were recruited from two outpatient clinics at the Reference Center for Older Adults of the Federal University of Minas Gerais. Participants underwent comprehensive geriatric assessments and DXA scans. CC was measured on the left leg. Low muscle mass was defined using the ALM index, and cutoff points were determined through receiver operating characteristic (ROC) curves. The participants were categorized through self\u2010reported ethnicity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Most participants were female (63.0%), with a mean age of 81.4\u2009\u00b1\u20098.2 years. The most commonly identified race was White (49.4%), followed by mixed race (43.8%) and Black (6.8%). For men, the CC cutoff was 35.0\u2009cm (AUC\u2009=\u20090.90; sensitivity\u2009=\u200990.2%, specificity\u2009=\u200972.6%), with no differences across age groups. For women aged 60\u201384, the cutoff was 34.0\u2009cm (AUC\u2009=\u20090.74; sensitivity = 77.1%, specificity\u2009=\u200960.8%), and for those \u226585 years of age, the cutoff was 32.0\u2009cm (AUC\u2009=\u20090.74; sensitivity\u2009=\u200986.8%, specificity\u2009=\u200958.3%).
