Abstract Background Extensive research has shown that the COVID-19 pandemic dramatically impacted the daily mobility of older adults. However, very little attention has been paid to the role of individual and built environmental factors in decline in older adults’ daily mobility during the pandemic. Methods Based on a cohort survey of 741 older adults in Hong Kong, we conducted a one-way ANOVA to explore the differences in determinants (individual or environmental factors) of older adults’ daily mobility between before and during the COVID-19 pandemic. Further, multilevel linear regression was performed to examine how individual characteristics and built environment factors are associated with changes in older adults’ daily mobility during the pandemic. Results Results show that the duration of active travel declined from 174.72 to 76.92 min per week, and that the public transport use frequency decreased from an average of 6.14 to 3.96 trips per week during the COVID-19 pandemic (before the rollout of vaccination programme). We also found residential density (p < 0.05) and the number of bus stop was negatively associated with the decline in their active travel (p < 0.01), while a higher destination mix was associated with more significant decrease in active travel (p < 0.01). A higher availability of recreational facilities in neighbourhoods was associated with a greater decrease in public transport use (p < 0.05). In addition, those who were older or having depressive symptoms, which are considered a vulnerable group, were negatively associated with decrease in their mobility (p < 0.001). Conclusions Maintaining mobility and social interactions are crucial for older adults’ health during the COVID-19 pandemic. This study found that individual and environmental factors differentially affected older adults’ active travel and public transport use during the pandemic. Our findings contribute to understanding the COVID-19 impact on daily mobility in older adults and support more effective active travel promotion policies in the post-pandemic future.
