Sociodemographic, clinical, and behavioral data were collected. Body mass (kg), height (m), and calf circumference (CC) (cm) were measured. SMM was also obtained through an anthropometric equation. Agreement analysis was performed. Receiver operating characteristic curve analysis, sensitivity, and specificity were calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 135 women were analyzed (55\u2009\u00b1\u200911.3\u2009years). The sample was predominantly nonwhite (69.7%), with \u2264\u20096\u2009months since diagnosis (81.5%), insufficiently active (59.3%), and with invasive breast carcinoma (70.4%). The Bland\u2013Altman test showed satisfactory agreement between SMM obtained by the anthropometric equation and the reference method (DXA) for adults and older women.
