目的探讨以色列特拉维夫市39132例单胎新生儿的出生体重、低出生体重（LBW）、极低出生体重（VLBW）、胎龄、早产（PTD）和极早产（VPTD）等妊娠结局与周围绿地的关系。在2000-2006年期间。根据OpenStreetMap构建的数据，将周围绿化度定义为250 m缓冲区内基于卫星的归一化植被指数（NDVI）的平均值，将与主要绿色空间的接近度定义为距离主要绿色空间（5000 m（2））边界300 m缓冲区内的居住地。线性回归（出生体重和胎龄）和logistic回归模型结果四分位距绿度增加1个，出生体重增加有统计学意义，四分位距绿度增加1个，出生体重增加有统计学意义（19.2 g，95% CI 13.3 - 25.1）和LBW风险降低（OR 0.84，95% CI 0.78 - 0.90）。极低出生体重的结果与此相同，但无统计学显著性。总的来说，未发现胎龄、PTD和VPTD之间存在相关性。研究结果是一致的，不同的缓冲区和绿色空间的大小和较强的协会之间观察到较低的社会经济地位。结论本研究证实了一些以前的研究表明，产妇接近绿色空间和出生体重之间的关联的结果。VLBW与VPTD的关系尚需进一步研究，这是以前从未研究过的。
Objective The objective of this study was to evaluate the associations between proximity to green spaces and surrounding greenness and pregnancy outcomes, such as birth weight, low birth weight (LBW), very LBW (VLBW), gestational age, preterm deliveries (PTD) and very PTD (VPTD).Methods This study was based on 39 132 singleton live births from a registry birth cohort in Tel Aviv, Israel, during 2000-2006. Surrounding greenness was defined as the average of satellite-based Normalised Difference Vegetation Index (NDVI) in 250 m buffers and proximity to major green spaces was defined as residence within a buffer of 300 m from boundaries of a major green space (5000 m(2)), based on data constructed from OpenStreetMap. Linear regression (for birth weight and gestational age) and logistic regressions models (for LBW, VLBW, PTD and VPTD) were used with adjustment for relevant covariates.Results An increase in 1 interquartile range greenness was associated with a statistically significant increase in birth weight (19.2 g 95% CI 13.3 to 25.1) and decreased risk of LBW (OR 0.84, 95% CI 0.78 to 0.90). Results for VLBW were in the same direction but were not statistically significant. In general, no associations were found for gestational age, PTD and VPTD. The findings were consistent with different buffer and green space sizes and stronger associations were observed among those of lower socioeconomic status.Conclusions This study confirms the results of a few previous studies demonstrating an association between maternal proximity to green spaces and birth weight. Further investigation is needed into the associations with VLBW and VPTD, which has never been studied before.
