Physical performance is a key early indicator of frailty and disability, and balance disorders impair the ability to carry out daily living activities. This study aimed to determine whether sociodemographic factors modify the association between physical performance and balance disorders among older adults in Peru.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A cross\u2010sectional analytical study was conducted using secondary data from two cohorts: the CEMENA Frailty Study (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20091896) and the ANDES\u2010FRAIL Study (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009453). After excluding participants with incomplete data, 2200 older adults aged \u2265\u200960 years were analyzed. Physical performance was measured using the Short Physical Performance Battery (SPPB), and balance disorders were assessed with the functional reach test (FRT). Crude and adjusted Poisson regression models stratified by sociodemographic variables were performed, adjusting for multimorbidity and functional dependence.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the participants, 52.09% had impaired physical performance, and 44.05% exhibited balance disorders. Impaired physical performance was significantly associated with balance disorders. Associations were observed among individuals aged \u2265\u200980\u2009years (PR: 2.72; 95% CI: 2.23\u20133.32), men (PR: 2.59; 95% CI: 2.22\u20133.04), those with &lt;\u200911\u2009years of education (PR: 2.43; 95% CI: 2.00\u20132.95), and coastal residents (PR: 2.63; 95% CI: 2.32\u20132.99).
