Understanding the Relationship between Neighbourhood Built Environment and Older Adults' Health from the Perspective of Housing Differentiation

Studies have revealed an association between the built environment and the health of older adults. However, few studies distinguish between the objective and perceived built environments and explore their associations with older adults' health, especially when considering housing differentiation. Drawing on a survey of 426 older adults in ten residential neighbourhoods in Dongfeng Township, Beijing, this study employed structural equation modelling and the Kruskal-Wallis test to analyse the relationship between the built environment of different housing types and older adults' health. The findings revealed that the objective and perceived environments were significantly associated with older adults' health, with physical activity and social interactions as mediating factors. The perceived built environment mediates the relationship between the objective built environment and older adults' health. Moreover, it was observed that the relationship between the built environment and older adults' health varied depending on housing type, which is a crucial reflection of spatial non-stationary in the relationship between health and environment. Therefore, the varying impacts of different housing types on older adults' health should not be overlooked when developing planning and other policies for aging-friendly cities.
