The purpose of this study was to examine associations between street connectivity and road traffic speed and neighborhood residents' use of parks and park-based physical activity.
Cross-sectional.
Kansas City, Missouri.
Participants were 893 adults from randomly selected households.
Both self-reported park use and park-based physical activity were dichotomized as some versus none. Intersection density was calculated around each participant, and network analysis was used to determine whether participants had to travel on or cross a road with traffic speed greater than 35 miles per hour (mph) to reach the closest park.
Multilevel logistic regression examined the association between intersection density and traffic speed wit park use and park-based physical activity.
Compared to those in the lowest intersection density quartile, participants in the third and fourth quartiles were more likely to use parks and to engage in physical activity in parks (odds ratio [OR] = 1.76-2.34; all p < .05). Likewise, compared to those who had a high-speed road on their way to the closest park, participants with slower traffic routes to parks were more likely to use the parks (OR = 1.47; 95% confidence interval [CI] = 1.05-1.92).
In addition to park proximity and the design of park features, ensuring direct and safe access to parks through street network design and traffic speed reduction strategies may be key to facilitating park-related physical activity.
本研究旨在探讨街道连通性、道路交通速度与邻里居民对公园的使用以及基于公园的体育活动之间的关联。
横断面研究。
密苏里州堪萨斯城。
参与者为来自随机抽取家庭的893名成年人。
自我报告的公园使用情况和基于公园的体育活动均分为“有”和“无”两类。计算每个参与者周围的交叉路口密度，并使用网络分析来确定参与者到达最近公园时是否必须在交通速度大于每小时35英里（mph）的道路上行驶或穿过该道路。
多水平逻辑回归分析检验交叉路口密度和交通速度与公园使用及基于公园的体育活动之间的关联。
与交叉路口密度最低四分位数组的参与者相比，第三和第四四分位数组的参与者更有可能使用公园并在公园内进行体育活动（比值比[OR]=1.76 - 2.34；所有p < 0.05）。同样，与前往最近公园途中有高速道路的参与者相比，前往公园交通路线较慢的参与者更有可能使用公园（OR = 1.47；95%置信区间[CI]=1.05 - 1.92）。
除了公园的距离和公园设施的设计外，通过街道网络设计和降低交通速度策略确保直接、安全地进入公园可能是促进与公园相关体育活动的关键。
