Access to public open space is important to increase leisure-time walking (LTW) in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares) and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey ( = 3145). LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m) from the geographic coordinates of the adults' residential addresses using a geographic information system. We used multilevel logistic regression taking account of clustering by census tracts and households, and with adjustment for social, demographics, and health characteristics. The main results showed that the presence of at least two recreational destinations within a 500-m buffer of participants' homes were associated with an increased odds of LTW compared with no destinations present (OR = 1.65; 95% CI 1.09-2.55). No associations were found for destinations further away. These results support actions outlined in the new urban plan for Sao Paulo city and could be used to highlight the importance access to a mix of public open spaces to promote physical activity in megacities of middle-income countries.
在高收入国家，公共开放空间对于增加休闲步行（LTW）十分重要，但在中等收入国家，相关证据却很少。我们进行了一项横断面分析，以研究参与圣保罗健康调查的成年人（n = 3145）住所附近不同公共开放空间（公园、自行车道和广场）的存在情况以及这些休闲目的地的组合与休闲步行之间的关系。休闲步行通过问卷调查进行评估。我们使用地理信息系统从成年人居住地址的地理坐标划定缓冲区（500米、1000米和1500米）。我们采用多水平逻辑回归分析，考虑到普查区和家庭的聚类情况，并对社会、人口统计学和健康特征进行了调整。主要结果显示，与住所500米缓冲区内没有休闲目的地相比，至少有两个休闲目的地与休闲步行几率增加相关（OR = 1.65；95%CI 1.09 - 2.55）。距离更远的目的地未发现有相关性。这些结果支持了圣保罗市新城市规划中概述的行动，并可用于强调获取多种公共开放空间对于促进中等收入国家大城市体育活动的重要性。
