Maintaining mobility is essential for healthy aging. A recently proposed unified framework conceptualizes mobility through three facets: actual mobility, perceived mobility, and locomotor capacity. Identifying determinants of each facet is important for understanding mobility and informing tailored mobility-focused interventions. This is particularly relevant for (pre-)frail older adults, who are especially vulnerable to mobility decline. The aim of this study was to examine associations of the three mobility facets with intrinsic capacity (IC) domains and environmental factors in this population. This cross-sectional study used baseline data from 385 (pre-)frail community-dwelling older participants (81.2 ± 5.9 years, 73.5% women) of the randomized controlled PromeTheus trial. Actual mobility was assessed with the Life-Space Assessment, perceived mobility with the function component of the Late-Life Function prospectively registered on March 11, 2021.
