This study explored the associations between the perceived walkability of neighborhood environment, walking time, and functional mobility by community-dwelling older adults in Hong Kong SAR, China. Seventy community-dwelling older adults (Mean age = 78.00 ± 7.40 years) participated in this study. Their perceived walkability of neighborhood environment was evaluated by the Chinese abbreviated version of Neighborhood Environment Walkability Survey (NEWS-A) and their walking time within a week was self-reported. The 10-Meter Walk Test and Tinetti Performance-Oriented Mobility Assessment (POMA) were used to assess the functional mobility of the participants, regarding their gait speed, balance, and gait performance, respectively. Results suggest that the perceived walkability of neighborhood environment (Aesthetics subscale) positively associated with the gait speed (rs =.35, p =.003), scores of the POMA-Balance (rs =.389, p =.001) and POMA-Gait (rs =.343, p =.004). This exploratory analysis augmented our contemporary understanding that older adults who could walk faster and with better balance and gait performance are associated with more positive perceived walkability of their neighborhood environment. It provides useful insight that could inform future high-impact investigations. [ABSTRACT FROM AUTHOR]

Background: Walking for transport can contribute to the accrual of health-enhancing levels of physical activity in elders. Identifying destinations and environmental conditions that facilitate this type of walking has public health significance. However, most findings are limited to Western, low-density locations, while a larger proportion of the global population resides in ultra-dense Asian metropolises. We investigated relationships of within-neighborhood objectively-measured destination categories and environmental attributes with walking for transport in 484 elders from an ultra-dense metropolis (Hong Kong). Methods: We estimated relationships of diversity (number of different types) and prevalence of within-neighborhood destination categories (environmental audits of 400 m buffers surrounding residential addresses) with transport-related walking (interviewer-administered questionnaire) in 484 Chinese-speaking elders able to walk unassisted and living in 32 neighborhoods stratified by socio-economic status and transport-related walkability. We examined the moderating effects of safety and pedestrian infrastructure-related neighborhood attributes on destination-walking associations. Results: Participants reported on average 569 and 254 min/week of overall and within-neighborhood walking for transport, respectively. The prevalence of public transit points and diversity of recreational destinations were positively related to overall walking for transport. The presence of a health clinic/service and place of worship, higher diversity in recreational destinations, and greater prevalence of non-food retails and services, food/grocery stores, and restaurants in the neighborhood were predictive of more within-neighborhood walking for transport. Neighborhood safety-related aspects moderated the relationship of overall walking for transport with the prevalence of public transit points, this being positive only in safe locations. Similar moderating effects of safety-related attributes were observed for the relationships of within-neighborhood walking for transport with diversity of recreational and entertainment destinations. Pedestrian-infrastructure attributes acted as moderators of associations of within-neighborhood walking for transport with prevalence of commercial destination categories. Composite destinations indices consisting of destination categories related to the specific measures of walking were positively associated with walking for transport. Conclusions: The availability of both non-commercial and commercial destinations may promote within-neighborhood walking for transport, while recreational facilities and public transit points may facilitate overall walking for transport. However, destination-rich areas need to also provide adequate levels of personal safety and a physically-unchallenging pedestrian network. [ABSTRACT FROM AUTHOR]
