Abstract

In research investigating built environment (BE) influences on physical activity (PA), inconsistent neighborhood definitions may contribute to inconsistent findings. Using data from the National Longitudinal Study of Adolescent Health (Wave I; 1994-95), we compared associations between moderate-vigorous PA (MVPA) and PA facility counts and street connectivity measures (intersection density and link:node ratio) within 1, 3, 5, and 8.05 km of each respondent's residence (Euclidean neighborhood buffers). BE-MVPA associations varied by BE characteristic, urbanicity, and sex. PA facilities within 3 km buffers and intersection density within 1 km buffers exhibited the most consistent associations with MVPA. Policy recommendations and corresponding research should address potential differences in relevant neighborhood areas across environment feature and population subgroup.

摘要

在研究建筑环境(BE)对身体活动(PA)的影响时,不一致的邻里定义可能导致研究结果不一致。本研究使用来自青少年健康纵向研究(Wave I;1994-1995 年)的数据,我们比较了在受访者居住处(欧几里得邻里缓冲区) 1、3、5 和 8.05 公里范围内,中高强度身体活动(MVPA)与 PA 设施数量和街道连通性指标(交叉口密度和链路:节点比)之间的关联。BE-MVPA 关联因 BE 特征、城市性和性别而异。3 公里缓冲区范围内的 PA 设施和 1 公里缓冲区范围内的交叉口密度与 MVPA 关联最为密切。政策建议和相应的研究应该针对不同环境特征和人口亚组的相关邻里区域的潜在差异。
