Attributes of the neighborhood-built environment are associated with self-reported physical activity, but only a few studies have concentrated on device-measured physical activity in Latin America. This study examines the associations of perceived neighborhood-built environment attributes, device-measured sedentary time, and light-intensity and moderate-to-vigorous physical activity in adults from 8 Latin American countries.
Data from Estudio Latinoamericano de Nutrición y Salud adult study, an observational multicountry study (N=2,478), were analyzed in 2020. Data were collected between 2014 and 2015. Perceived neighborhood-built environment attributes were measured using the Neighbourhood Environment Walkability Survey. Sedentary time, light-intensity physical activity, and moderate-to-vigorous physical activity data were collected using accelerometers.
No associations between perceived neighborhood-built environment attributes and sedentary time were found. Positive perceptions of walking/cycling facilities (β=6.50, 95% CI=2.12, 10.39) were associated with more light-intensity physical activity. Perceptions of better aesthetics (Argentina) and better walking/cycling facilities (Brazil and Ecuador) were positively associated with light-intensity physical activity. Land use mix-diversity (β=0.14, 95% CI=0.03, 0.25), walking/cycling facilities (β=0.16, 95% CI=0.05, 0.27), aesthetics (β=0.16, 95% CI=0.02, 0.30), and safety from traffic (β=0.18, 95% CI=0.05, 0.24) were positively associated with moderate-to-vigorous physical activity. Land use mix-diversity, street connectivity, and safety from traffic were positively associated with moderate-to-vigorous physical activity in Venezuela.
These findings have implications for policy recommendations, which can guide policies to promote physical activity in the region. Land use mix-diversity, walking/cycling facilities, aesthetics, and safety from traffic can maintain or increase the levels of light-intensity and moderate-to-vigorous physical activity among Latin American adults.
社区建成环境的属性与自我报告的身体活动相关，但在拉丁美洲，仅有少数研究关注通过设备测量的身体活动。本研究调查了来自8个拉丁美洲国家的成年人对社区建成环境属性的认知、通过设备测量的久坐时间、轻度身体活动以及中等到剧烈身体活动之间的关联。
对拉丁美洲营养与健康成人研究（一项观察性多国研究，N = 2478）2020年的数据进行分析。数据收集于2014年至2015年期间。使用社区环境可步行性调查来测量对社区建成环境属性的认知。使用加速度计收集久坐时间、轻度身体活动以及中等到剧烈身体活动的数据。
未发现对社区建成环境属性的认知与久坐时间之间存在关联。对步行/骑行设施的积极认知（β = 6.50，95%置信区间 = 2.12，10.39）与更多的轻度身体活动相关。对更好的美学（阿根廷）以及更好的步行/骑行设施（巴西和厄瓜多尔）的认知与轻度身体活动呈正相关。土地利用混合多样性（β = 0.14，95%置信区间 = 0.03，0.25）、步行/骑行设施（β = 0.16，95%置信区间 = 0.05，0.27）、美学（β = 0.16，95%置信区间 = 0.02，0.30）以及交通安全（β = 0.18，95%置信区间 = 0.05，0.24）与中等到剧烈身体活动呈正相关。在委内瑞拉，土地利用混合多样性、街道连通性以及交通安全与中等到剧烈身体活动呈正相关。
这些发现对政策建议具有启示意义，可为该地区促进身体活动的政策提供指导。土地利用混合多样性、步行/骑行设施、美学以及交通安全可维持或提高拉丁美洲成年人的轻度身体活动以及中等到剧烈身体活动水平。
