Abstract

Objective: To evaluate the association between gestational age and green areas, urban built areas, and the concentration of particulate matter 2.5 (PM2.5) in the city of São Paulo, analyzing the irregular distribution of these areas and pollution levels above the recommended level.

Methods: The study population consisted of a cohort of live births from 2012, and data from the Live Birth Information System (Sinasc) of the city of São Paulo were used. Using satellite images and supervised classification, the distribution and quantity of green areas and built areas in the city of São Paulo was obtained, as well as the concentrations of PM2.5. Logistic regressions were used to obtain possible associations.

Results: The results of the study show that a lower percentage of green areas is significantly associated with a higher chance of preterm births. A higher building density was positively associated with the odds ratio for preterm birth. We did not find any significant associations between air pollution (PM2.5) and preterm births.

Conclusions: The results of this study show that greener areas are less associated with preterm births when compared with less green areas.

土地覆盖和空气污染对早产风险的影响。

目的评估圣保罗市胎龄与绿化区、城市建筑区和颗粒物2.5（PM2.5）浓度之间的关系，分析这些区域的不规则分布和高于建议水平的污染程度：研究对象包括2012年出生的活产婴儿，数据来自圣保罗市的活产婴儿信息系统（Sinasc）。通过卫星图像和监督分类，获得了圣保罗市绿地和建筑区的分布和数量，以及PM2.5的浓度。使用逻辑回归法得出可能的关联：研究结果表明，绿地比例越低，早产几率越高。较高的建筑密度与早产几率呈正相关。我们没有发现空气污染（PM2.5）与早产之间有任何明显的关联：这项研究的结果表明，与绿化较少的地区相比，绿化较多的地区与早产的关系较小。
