“…Nevertheless, studies that explore the underlying mechanism (mediators) between self-reported and capacity-based mobility outcomes are scarce. To the best of our knowledge, this study is the first to examine the relationship between several self-reported (LEFS, Mänty Preclinical Limitation Scale, LSQ) and capacity-based mobility (SPPB, 6MWT, 10mWT) outcomes in a developing context while exploring the mediating factors chosen from comprehensive mobility determinants ( Kalu et al, 2022a , 2022b , 2023 ). We found the correlation between self-reported (LEFS and Mänty Preclinical Limitation scale) and capacity-based (SPPB and 6MWT) mobility measures ranged from poor to fair, in the expected direction.…”

“…We proceeded with caution in interpreting this finding, as there are inherent problems with cross-sectional mediation analysis ( Fairchild & McDaniel, 2017 ). Nevertheless, age is a well-established predictor of mobility outcomes (self-reported and capacity-based) and could explain why it partially mediates the association ( Kalu et al, 2023 ; Nicolson et al, 2021 ). Moreso, age-related physiological (for example, reduced muscle mass or power), mechanical, such as joint articular degeneration due to “wear’ and “tear” and psych-cognitive changes unfold simultaneously with mobility decline among older adults could provide another plausible reason for age mediating role in the association between self-reported and capacity-based mobility outcomes ( Freiberger et al, 2020 ).…”

“…These differing correlations highlight the need for studies in different contexts, especially in developing countries with a population of predominantly different cultures and races. A scoping review identified that in general, Whites had faster gait speed, higher life space scores, or access to transportation and amenities promoting mobility than Blacks and Hispanics, and these differences could be due to the accumulated exposure to adverse health events and disadvantages that Blacks and Hispanics face across their life course ( Kalu et al, 2023 ). Similarly, Whites have been found to overestimate their physical activity level compared to Blacks ( Bazargan-Hejazi et al, 2017 ).…”

Background and Objectives Although the association between self-reported and capacity-based mobility outcomes is prominently researched, the pathways through which self-reported measures affect capacity-based measures remains poorly understood. Therefore, our study examines the association between self-reported and capacity-based mobility measures and explores which mobility determinants mediate the association in Nigerian community-dwelling older adults. Research Design and Methods This cross-sectional study included 169 older adults [mean age (SD) = 67.7 (7.0)]. Capacity-based mobility outcomes included the Short Physical Performance Battery (SPPB), the 6-Minute Walk Test(6MWT), and the 10-Meter Walk Test(10mWT), while the self-reported mobility outcomes included the Lower Extremity Functional Scale (LEFS), the Life Space Questionnaire(LSQ), and the Mänty Preclinical Mobility Scale(inability to walk 2km, 0.5km or climb a flight of stairs). Spearman's correlations were conducted to examine the relationship between self-reported and capacity-based mobility measures, while structural equation modelling was used to determine the mediators. Results The correlation between SPPB and LEFS (rho = 0.284), inability to walk 2km (rho = -0.244), and 0.5km (rho = -0.251) were fair, while the correlation between SPPB and inability to climb a flight of stairs (rho = -0.190) was poor. Similarly, correlations between 6MWT and the LEFS (rho = 0.286), inability to walk 2 km (rho = -0.269), and 0.5km (rho = -0.303) were fair. The 6WMT was poorly correlated with inability to climb one flight of stairs (rho = -0.233). The LSQ was not correlated with SPPB or 10mWT. Age was the only significant mediator, while the number of chronic conditions and cognitive status were not. Discussion and Implications The correlation between self-reported and capacity-based mobility outcomes in older adults in Nigeria is lower than those in developed countries. Our analysis provides a foundation to explore mobility determinants that could be predictive mediators for mobility outcomes, making meaningful contributions to explaining mobility complexities.
