Chronic pain was assessed through self-report and defined as pain persisting for \u22653 months. IC was evaluated across locomotor, vitality, cognitive, psychological, and sensory domains with validated tools. Logistic regression was used to examine the association between chronic pain and IC decline status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 820 participants were analyzed. Chronic pain prevalence was 75.3, and 87.0% were classified as having IC decline status. Locomotor and vitality were the most affected domains. Chronic pain was strongly associated with IC decline status (adjusted OR = 4.77, 95% CI: 3.04\u20137.49). Age \u226580 years increased the risk of IC decline status, while polypharmacy (\u22655 medications) showed a protective effect. No significant interactions were found between chronic pain and age or polypharmacy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Chronic pain was highly prevalent and independently associated with IC decline status in older patients with chronic diseases. Locomotor and vitality were the most vulnerable domains.
