To analyze the spatial distribution of the prevalence of leisure-time physical activity (LTPA) in a Brazilian urban area and its association with the characteristics of the physical and social environments.
A cross-sectional study conducted with data from the Surveillance System for Risk and Protective Factors for Chronic Diseases from the years 2008-2010, in Belo Horizonte, state of Minas Gerais, Brazil. The outcome was the practice of LTPA and the independent variables were residential and population density, the density of places for physical activity, homicide rates, average family income, and health vulnerability index. The spatial scanning technique was employed to identify clusters with a high prevalence of PA at leisure time. The Mann-Whitney test was used to compare variables inside and outside the cluster.
The sample included 5,779 participants, 33.3% (SE = 0.73) of whom reported sufficient PA during leisure time. We identified a significant cluster of a high prevalence of LTPA. After adjustments, the cluster presented a radius of 3,041.99 meters and 603 individuals, and 293 (48.6%) of them reported sufficient LTPA. The probability of performing sufficient LTPA in the cluster was 27% higher (PR = 1.27; p = 0.002) than in the coverage areas of primary healthcare units outside the cluster. There was a higher density of places for LTPA practice, higher population and residential density, and higher family income in the cluster.
The results evidenced a cluster of high prevalence of LTPA in a privileged physical and socioeconomic environment in Belo Horizonte, even after adjustments, demonstrating that reducing inequalities can increase LTPA.
分析巴西某城市休闲体力活动（LTPA）流行率的空间分布及其与物理和社会环境特征的关系。
本横断面研究使用了来自巴西米纳斯吉拉斯州贝洛奥里藏特市 2008-2010 年慢性病风险和保护因素监测系统的数据。结果是 LTPA 的实践，而独立变量是居住和人口密度、体育活动场所密度、凶杀率、平均家庭收入和健康脆弱性指数。采用空间扫描技术识别休闲时间 PA 高流行率的聚类。采用曼-惠特尼检验比较聚类内和聚类外的变量。
该样本包括 5779 名参与者，其中 33.3%（SE=0.73）报告了足够的休闲时间 PA。我们发现了一个高流行率的 LTPA 显著聚类。调整后，聚类半径为 3041.99 米，有 603 人，其中 293 人（48.6%）报告了足够的 LTPA。在聚类中进行足够的 LTPA 的概率高 27%（PR=1.27；p=0.002），而在聚类外的初级保健单位覆盖区域则低 27%。在聚类中，有更多的 LTPA 实践场所、更高的人口和居住密度以及更高的家庭收入。
结果表明，在贝洛奥里藏特，即使在调整后，仍然存在一个高流行率的 LTPA 聚类，这是一个优越的物理和社会经济环境，表明减少不平等可以增加 LTPA。
