The design is a cross-sectional study, which used the baseline assessment of CLSA.
A total of 29,569 participants from the CLSA were included after excluding those 1) lacking walking speed data and/or 2) diagnosed with dementia or AD. Participants were categorized by age groups and MCR diagnosis. Intra-group comparisons were completed using the unpaired t-test or Chi square test. Multiple logistic regressions were also performed to examine the association between MCR and depressive symptomatology, while adjusting for multiple variables.
