评估加拿大成年人的社区步行适宜性（基于地理信息系统 (GIS) 衍生的街道连通性、土地利用组合、人口密度和步行分数）与自我报告的实用步行和加速计评估的每日步数之间的关联。对作为加拿大健康措施调查（2007-2009 年）一部分收集的数据进行横断面分析。位于加拿大大西洋省、魁北克省、安大略省、大草原省和不列颠哥伦比亚省的家庭社区（围绕参与者邮政编码质心的 500 米多边形街道网络缓冲区）。 5605 人参与了调查。 3727 名成年人（≥ 18 岁）完成了计算机辅助访谈并参加了流动诊所评估。分析基于那些拥有完整暴露、结果和协变量数据的人 (n=2949)。 GIS 衍生的步行性（基于土地利用组合、街道连通性和人口密度）；步行得分。自我报告功利性步行；加速度计评估的每日步数。没有观察到邻里步行能力和每日步数之间存在重要关系。然而，报告更多功利性步行的参与者积累了更多步数（<1 小时/周：6613步/天，95% CI 6251至6975；1至5 小时/周：6768步/天，95% CI 6420至7117；≥6 小时/周：7391步/天，95% CI 6972至 7811）。出于功利目的，步行能力与每周步行≥1 小时的几率之间存在正相关关系（例如，GIS 衍生步行能力的 Q4 与 Q1：OR=1.66，95% CI 1.31 至 2.11；Q3 与 Q1：OR=1.41，95% CI 1.14 至 1.76；Q2 与 Q1：OR=1.13，95% CI 0.91 至 1.39），与年龄、性别、体重指数、已婚/普通法状况、家庭年收入、家中有孩子、移民身份、情绪障碍、健康状况、吸烟者和季节无关。与预期相反，居住在更适合步行的加拿大社区与更多的步行总量并没有关系。然而，功利性步行和每日步数是相关的，步行能力与功利性步行呈正相关。
To estimate the associations of neighbourhood walkability (based on Geographic Information System (GIS)-derived measures of street connectivity, land use mix, and population density and the Walk Score) with self-reported utilitarian walking and accelerometer-assessed daily steps in Canadian adults. A cross-sectional analysis of data collected as part of the Canadian Health Measures Survey (2007–2009). Home neighbourhoods (500 m polygonal street network buffers around the centroid of the participant's postal code) located in Atlantic Canada, Québec, Ontario, the Prairies and British Columbia. 5605 individuals participated in the survey. 3727 adults (≥18 years) completed a computer-assisted interview and attended a mobile clinic assessment. Analyses were based on those who had complete exposure, outcome and covariate data (n=2949). GIS-derived walkability (based on land use mix, street connectivity and population density); Walk Score. Self-reported utilitarian walking; accelerometer-assessed daily steps. No important relationship was observed between neighbourhood walkability and daily steps. Participants who reported more utilitarian walking, however, accumulated more steps (<1 h/week: 6613 steps/day, 95% CI 6251 to 6975; 1 to 5 h/week: 6768 steps/day, 95% CI 6420 to 7117; ≥6 h/week: 7391 steps/day, 95% CI 6972 to 7811). There was a positive graded association between walkability and odds of walking ≥1 h/week for utilitarian purposes (eg, Q4 vs Q1 of GIS-derived walkability: OR=1.66, 95% CI 1.31 to 2.11; Q3 vs Q1: OR=1.41, 95% CI 1.14 to 1.76; Q2 vs Q1: OR=1.13, 95% CI 0.91 to 1.39) independent of age, sex, body mass index, married/common law status, annual household income, having children in the household, immigrant status, mood disorder, perceived health, ever smoker and season. Contrary to expectations, living in more walkable Canadian neighbourhoods was not associated with more total walking. Utilitarian walking and daily steps were, however, correlated and walkability demonstrated a positive graded relationship with utilitarian walking.
