Park proximity and multiple health outcomes: Findings from the United States and Australia
Methods: Data were collected in Kansas City, Missouri (n=891) and Melbourne, Australia (females only, n=1830). For both locations, ArcGIS10 was used to calculate three measures of proximity (distance to the closest park, number of parks, and total park area) within a 1-mile network distance of residence and participants were categorized as low, medium, or high. Health data were collected via mail surveys and participants were classified by level of PA (meets vs. does not meet recommendations), sedentary behavior (0-2 hours vs. >2 hours/day), and weight status (healthy vs. overweight/obese). Multilevel logistic regression analyses explored associations between each park proximity measure and health outcome controlling for demographic characteristics.
Results: In the U.S., a high amount of park area was associated with lower odds of high sedentary behavior among females (OR=0.42,CI=0.20-0.88). In Australian women, low distance to a park was associated with greater odds of meeting PA recommendations (OR=1.39,CI=1.06-1.82) and having a high number of parks was related to lower odds of being overweight/obese (OR=0.72,CI=0.57-0.92).
Conclusion/Discussion: These findings across diverse contexts worldwide lend increased credibility to policy and environmental actions to increase access to parks to promote PA and community health.

Qualified on the content I am responsible for because: I am a doctoral candidate in the Arnold School of Public Health at the University of South Carolina. My research focuses on how built environment attributes and community design promote healthy eating and active living, especially among youth. I have been a project manager on several research studies and co-authored numerous manuscripts, abstracts, and grants. Additionally, I have instructed physical activity and public health-related courses at the collegiate level.
