To analyze the perceived availability of public open space (POS) in the neighborhood for physical activity (PA) over the years and its association to practice of leisure-time physical activity (LTPA) among Brazilian adult population.
Data from the surveillance system of risk and protection factors for chronic diseases by telephone survey (Vigitel) from 2011 to 2015 were analyzed (n = 247,548). Prais-Winsten regression was used to investigate the trend of the perceived availability of POS, and Poisson regression to analyze its association to the LTPA.
The perceived availability of POS in the neighborhood for PA remained fairly stable, from 73.4% in 2011 to 74.0% in 2015. The perception of this availability positively associated with the sufficient practice of LTPA (≥ 150 min/week) (RP = 1.27; p < 0.05), and with the practice of different types, weekly frequency and daily duration of the activities.
In addition to the building and maintenance of POS, the proximity and physical accessibility of the population must be guaranteed, so that those spaces are perceived as a favorable environment for the practice of LTPA.
分析多年来社区内公共开放空间（POS）对身体活动（PA）的感知可用性及其与巴西成年人群休闲时间身体活动（LTPA）实践的关系。
分析了 2011 年至 2015 年通过电话调查（Vigitel）进行的慢性病风险和保护因素监测系统的数据（n=247548）。采用 Prais-Winsten 回归分析 POS 感知可用性的趋势，采用泊松回归分析其与 LTPA 的关系。
社区内 PA 的 POS 感知可用性相对稳定，从 2011 年的 73.4%稳定到 2015 年的 74.0%。对这种可用性的感知与充足的 LTPA 实践（≥150 分钟/周）（RP=1.27；p<0.05）以及不同类型、每周频率和活动每日持续时间的实践呈正相关。
除了建设和维护 POS 外，还必须保证人口的接近度和身体可达性，以便这些空间被视为进行 LTPA 的有利环境。
