背景：绿色空间与改善身心健康有关；然而，关于绿地对怀孕影响的现有证据很少。目的：我们调查了周围绿色度与出生体重、头围和分娩孕龄之间的关联。方法：本研究基于来自四个西班牙出生队列（阿斯图里亚斯、吉普斯夸、萨瓦德尔和巴伦西亚）的 2,393 名单胎活产婴儿，这些出生队列位于伊比利亚半岛两个气候和植被模式不同的地区（2003-2008 年）。我们将周围绿度定义为 2007 年每个母亲居住地周围 100 m、250 m 和 500 m 缓冲区内基于卫星的归一化植被指数 (NDVI)（Landsat 4-5 TM 数据，分辨率为 30 m × 30 m）的平均值。使用对潜在混杂因素和随机队列效应进行调整的单独线性混合模型来估计周围绿化度增加 1 个四分位距时出生体重、头围和胎龄的变化。结果：较高的周围绿化度与出生体重和头围的增加相关[调整后的回归系数（95%置信区间）为44.2克（20.2克，68.2克）和1.7毫米（0.5毫米，2.9毫米），500米缓冲区内平均NDVI的四分位数范围增加]，但与胎龄无关。这些发现对于缓冲区大小的选择和周围绿化数据采集的季节以及分析仅限于足月出生的情况来说是强有力的。分层分析表明，受教育程度较低的母亲的孩子之间的关联性更强，这表明周围的绿化带来的好处更大。结论：我们的研究结果表明，周围的绿色对胎儿生长的测量有有益的影响，但对妊娠长度没有影响。
Background: Green spaces have been associated with improved physical and mental health; however, the available evidence on the impact of green spaces on pregnancy is scarce. Objectives: We investigated the association between surrounding greenness and birth weight, head circumference, and gestational age at delivery. Methods: This study was based on 2,393 singleton live births from four Spanish birth cohorts (Asturias, Gipuzkoa, Sabadell, and Valencia) located in two regions of the Iberian Peninsula with distinct climates and vegetation patterns (2003–2008). We defined surrounding greenness as average of satellite-based Normalized Difference Vegetation Index (NDVI) (Landsat 4–5 TM data at 30 m × 30 m resolution) during 2007 in buffers of 100 m, 250 m, and 500 m around each maternal place of residence. Separate linear mixed models with adjustment for potential confounders and a random cohort effect were used to estimate the change in birth weight, head circumference, and gestational age for 1-interquartile range increase in surrounding greenness. Results: Higher surrounding greenness was associated with increases in birth weight and head circumference [adjusted regression coefficients (95% confidence interval) of 44.2 g (20.2 g, 68.2 g) and 1.7 mm (0.5 mm, 2.9 mm) for an interquartile range increase in average NDVI within a 500-m buffer] but not gestational age. These findings were robust against the choice of the buffer size and the season of data acquisition for surrounding greenness, and when the analysis was limited to term births. Stratified analyses indicated stronger associations among children of mothers with lower education, suggesting greater benefits from surrounding greenness. Conclusions: Our findings suggest a beneficial impact of surrounding greenness on measures of fetal growth but not pregnancy length.
