Characteristics of the neighborhood built environment are associated with physical activity (PA). However, few studies with representative samples have examined environmental correlates of domain-specific PA in Latin America. We examined the associations of the perceived neighborhood built environment with domain-specific PA in a large sample of adults from eight Latin American countries.
This study examined data from 8185 adults (aged 18-65 years) from eight Latin American countries. The Neighbourhood Environment Walkability Survey - Abbreviated (NEWS-A) scale was used to assess perceptions of land use mix-diversity, land use mix-access, street connectivity, walking/cycling facilities, aesthetics, safety from traffic, and safety from crime. Perceived proximity from home to public open spaces (metropolitan parks, playgrounds, public squares) and to shopping centers was also measured. Transport-related and leisure-time PA were assessed using the long form of the International Physical Activity Questionnaire. Both logistic and linear regression models were estimated on pooled data.
Perceptions of higher land use mix-access (OR: 1.40; 95% CI: 1.22,1.61), the existence of many alternative routes in the neighbourhood (1.12; 1.04,1.20), slow speed of traffic (1.19; 1.03,1.35) and few drivers exceeding the speed limits (1.09; 1.03,1.15) were associated with greater odds of reporting at least 10 min/week of transport-related PA. Perceptions of higher levels of land use mix-diversity, better aesthetics and greater safety from crime, the presence of crosswalks and pedestrian signals, and greater proximity of shopping centers were associated with more min/week of transport-related PA. Perceptions of higher land use mix-diversity (1.12; 1.05,1.20), higher land use mix-access (1.27; 1.13,1.43), more walking/cycling facilities (1.18; 1.09,1.28), and better aesthetics (1.10; 1.02,1.18) were associated with greater odds of engaging in at least 10 min/week of leisure-time PA versus none. Perceptions of higher land use mix-diversity were associated with more min/week of leisure PA.
Different perceived neighborhood built environment characteristics were associated with domain-specific PA among adults from Latin America countries. Interventions designed to modify perceptions of the neighbourhood built environment might influence initiation or maintenance of domain-specific PA.

邻里环境的特点与身体活动（PA）有关。然而，很少有具有代表性样本的研究调查了拉丁美洲特定领域 PA 的环境相关性。我们在来自八个拉丁美洲国家的大量成年人样本中研究了对感知邻里环境与特定领域 PA 的关联。
本研究分析了来自八个拉丁美洲国家的 8185 名成年人（18-65 岁）的数据。使用邻里环境步行性调查-简化版（NEWS-A）量表评估对土地利用混合多样性、土地利用混合可达性、街道连通性、步行/自行车设施、美观、交通安全性和犯罪安全性的看法。还测量了从家到公共开放空间（城市公园、游乐场、公共广场）和购物中心的感知接近度。使用国际体力活动问卷的长式评估与交通相关和休闲时间 PA。在汇总数据上估计了逻辑和线性回归模型。
感知更高的土地利用混合可达性（OR：1.40；95%CI：1.22，1.61）、邻里中有许多替代路线（1.12；1.04，1.20）、交通速度较慢（1.19；1.03，1.35）和很少有司机超速（1.09；1.03，1.15）与报告至少 10 分钟/周交通相关 PA 的几率更高相关。感知更高水平的土地利用混合多样性、更好的美观和更高的犯罪安全性、人行横道和行人信号的存在以及与购物中心的更大接近度与更多的交通相关 PA 周数相关。感知更高的土地利用混合多样性（1.12；1.05，1.20）、更高的土地利用混合可达性（1.27；1.13，1.43）、更多的步行/自行车设施（1.18；1.09，1.28）和更好的美观（1.10；1.02，1.18）与进行至少 10 分钟/周的休闲时间 PA 的几率更高相关，而不是没有。感知更高的土地利用混合多样性与更多的休闲时间 PA 周数相关。
不同的感知邻里环境特征与来自拉丁美洲国家的成年人特定领域 PA 相关。旨在改变邻里环境感知的干预措施可能会影响特定领域 PA 的开始或维持。
