Beyond Proximity and Towards Equity: A Multidimensional View of Urban Greenspace Access.

Park access is primarily conceived of as a question of proximity. We sought to develop a multidimensional tool based on a broad theory of green space access to better understand objective and subjective factors that capture varying dimensions of urban green space access that may be associated with its use. Methods: We conducted a cross-sectional study in two communities bordering a large park in Baltimore City, Maryland. We randomly selected households for an in-person survey conducted between April to September 2019. Our primary outcome was self-reported number of park visits over the last 30 days. The main independent variables conceptualized park access based on Penchansky and Thomas' theory of access. Results: Based on 87 respondents, living within a 10-minute walk was not associated with park use. Park use was associated with the perception that there were park events that individuals could participate in (adjusted IRR 6.83 [95% CI 2.57, 18.2]) and feeling safe in the park during the day (adjusted IRR 6.26 [95% CI 2.18, 18.0]). Those who reported that living near the park was affordable reported fewer park visits (adjusted IRR 0.53 [95% CI 0.32, 0.86]). Conclusions: Physical proximity was not significantly associated with green space use, but perceptions of safety, programming, and neighborhood affordability were. Our findings highlight the importance of subjective factors as part of a broader theory of park access.
