Objective: To evaluate sedentary behaviors among older adults in residential care homes and explore potential mechanisms leading to sedentary behaviors based on the Capability, Opportunity, and Motivation to Behavior (COM-B) model. Design: Cross-sectional study. Setting and Participants: We collected data from 329 residents who lived in 11 residential care homes in China. Method: We collected self-reported survey data on resident demographics, sedentary behavior, activities of daily living (ADLs), social support, exercise self-efficacy, and depressive symptoms. Mean and standard deviation were used to describe the sedentary behavior of older adults in care homes. We drew on the COM-B model and constructed a structural equation model to assess the interrelationships of ADLs, social support, exercise self-efficacy, depressive symptoms, and sedentary behavior. Result: The average daily sedentary time of older adults in our sample was 11.4 hours (SD = 2.6). Social support not only directly influenced sedentary behavior of older adults in care homes (β = 0.042; P = .039; 95% CI, −0.054 to −0.031]), but also indirectly through exercise self-efficacy (β = 0.003; P < .001; 95% CI, −0.023 to −0.011]) and depressive symptoms (β = 0.003; P < .001; 95% CI, −0.018 to −0.006) affected sedentary behaviors. ADLs indirectly affected sedentary behaviors through exercise self-efficacy (β = 0.029; P < .001; 95% CI, −0.220 to −0.107) and depressive symptoms (β = 0.099; P < .001; 95% CI, −0.161 to −0.053). Conclusions and Implications: The high levels of sedentary behaviors among our sample of residents warrant awareness among long-term care staff and managers. Potential strategies for reducing sedentary behaviors include promoting social support, enhancing exercise self-efficacy, and managing depressive symptoms. © 2025
