GS burden (0 to \u22654) and specific comorbidities were examined against overall IC impairment and its five domains (locomotion, cognition, sensory, vitality, psychological). Adjusted prevalence ratios (PR) were estimated using multivariable modified Poisson regression models. Sensitivity analyses accounted for frailty, disability, and conceptual overlap between exposure and outcome domains, and the exclusion of severe end-stage deficits.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Overall, 69.6% of participants had \u22651 GS. IC impairment prevalence increased progressively with GS burden, from 35.6% (0 GS) to 84.7% (\u22654 GS). Compared to those with 0 GS, participants with \u22654 GS had a substantially higher prevalence of overall IC impairment (PR = 2.00; 95% CI: 1.76\u20132.27), locomotion difficulties (PR = 6.52), and psychological problems (PR = 6.68; all\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt; 0.001). Individually, delirium symptoms showed the strongest association with cognitive (PR = 4.09) and overall IC impairment (PR = 1.48). Specific dyadic GS combinations (e.g., anxiety paired with chronic constipation) remained independently associated with IC impairment even after adjusting for the total concurrent GS burden. Sensitivity analyses confirmed that cumulative GS associations remained stable after adjusting for physical vulnerability (\u22654 GS PR = 1.73) and excluding severe deficits. No significant interactions were observed by age, sex, or region.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In community-dwelling older adults with self-reported physician-diagnosed CHD, a higher GS burden is strongly and independently associated with IC impairment, reflecting a functional continuum from early capacity declines to advanced physical vulnerability. This graded relationship persists even when accounting for physical vulnerability, highlighting the critical value of identifying high-risk GS clusters to proactively manage IC.<\/jats:p>\n
