社区的可步行性会影响身体活动。我们评估了Walk Score®用于评估社区可步行性的有效性，该评估基于社区可步行性的GIS（客观）指标，地址来自四个美国大都市区，具有几个街道网络缓冲距离（即，400米、800米和1,600米）。地址数据来自基督教青年会-哈佛大学课后食品和健身项目，肥胖预防干预涉及5-11岁的儿童和他们的家庭参加基督教青年会管理的，位于美国四个地理位置不同的大都市地区的课后计划（n = 733）。GIS数据被用来衡量多个目标指标的邻里步行。步行得分也获得了参与者的住宅地址。步行得分和地理信息系统邻里步行能力指标之间的斯皮尔曼相关性进行了计算，以及斯皮尔曼相关性占空间自相关。步行得分与地理信息系统的街区步行能力指标如零售点密度和交叉口密度之间存在许多显着的中度相关性（p < 0.05）。大小不同的地理信息系统指标的邻里步行。相关性一般随着空间尺度的增大而增强，并且存在一些地理差异。Walk Score®是免费的，可供公共卫生研究人员和从业人员公开使用。我们的研究结果表明，步行评分是评估社区步行能力某些方面的有效措施，特别是在1600米的缓冲区。因此，我们的研究证实并扩展了先前研究结果的普遍性，证明步行评分是在多个地理位置和多个空间尺度上估计邻里步行能力的有效措施。
Neighborhood walkability can influence physical activity. We evaluated the validity of Walk Score® for assessing neighborhood walkability based on GIS (objective) indicators of neighborhood walkability with addresses from four US metropolitan areas with several street network buffer distances (i.e., 400-, 800-, and 1,600-meters). Address data come from the YMCA-Harvard After School Food and Fitness Project, an obesity prevention intervention involving children aged 5–11 years and their families participating in YMCA-administered, after-school programs located in four geographically diverse metropolitan areas in the US (n = 733). GIS data were used to measure multiple objective indicators of neighborhood walkability. Walk Scores were also obtained for the participant’s residential addresses. Spearman correlations between Walk Scores and the GIS neighborhood walkability indicators were calculated as well as Spearman correlations accounting for spatial autocorrelation. There were many significant moderate correlations between Walk Scores and the GIS neighborhood walkability indicators such as density of retail destinations and intersection density (p < 0.05). The magnitude varied by the GIS indicator of neighborhood walkability. Correlations generally became stronger with a larger spatial scale, and there were some geographic differences. Walk Score® is free and publicly available for public health researchers and practitioners. Results from our study suggest that Walk Score® is a valid measure of estimating certain aspects of neighborhood walkability, particularly at the 1600-meter buffer. As such, our study confirms and extends the generalizability of previous findings demonstrating that Walk Score is a valid measure of estimating neighborhood walkability in multiple geographic locations and at multiple spatial scales.
