这项研究探讨了智能成长和传统设计社区中儿童的绿色暴露与自由生活身体活动行为之间的关系。归一化植被指数 (NDVI) 用于量化儿童 (n=208) 在 30 秒历元加速计和 GPS 数据点处的绿化暴露。具有用于解决空间自相关的核密度平滑项的广义线性混合模型适合分析住宅区活动数据。排除家庭和学校时间的活动，一项时代水平的分析发现，短暂的绿色暴露与同时进行中度至剧烈体力活动（MVPA）的可能性呈正相关。对于精明增长的居民来说，这种关联更为强烈，他们在接触绿色植物的时间增加 10% 至 90% 时，获得 MVPA 的几率增加了 39%（OR=1.39，95% CI 1.36-1.44）。一项受试者水平分析发现，每天接触绿色空间超过 20 分钟（>90%）的儿童的每日 MVPA 率是每日接触绿色空间几乎为零的儿童的近 5 倍（95% CI 3.09-7.20）。
This study examined relationships between greenness exposure and free-living physical activity behavior of children in smart growth and conventionally designed communities. Normalized Difference Vegetation Index (NDVI) was used to quantify children’s (n=208) greenness exposure at 30-second epoch accelerometer and GPS data points. A generalized linear mixed model with a kernel density smoothing term for addressing spatial autocorrelation was fit to analyze residential neighborhood activity data. Excluding activity at home and school-time, an epoch-level analysis found momentary greenness exposure was positively associated with the likelihood of contemporaneous moderate-to-vigorous physical activity (MVPA). This association was stronger for smart growth residents who experienced a 39% increase in odds of MVPA for a 10th to 90th percentile increase in exposure to greenness (OR=1.39, 95% CI 1.36–1.44). A subject-level analysis found children who experienced >20 minutes of daily exposure to greener spaces (>90th percentile) engaged in nearly 5 times the daily rate of MVPA of children with nearly zero daily exposure to greener spaces (95% CI 3.09–7.20).
