Comment on 'Green Space, health inequality, and pregnancy'

摘要

We read with great interest a recent Environment International article—Green Space, health inequality, and pregnancy—which explores the relationship between greenness around a mother's home, proximity to green space, and pregnancy outcomes in Barcelona (Dadvand et al., in press). The authors were clearly unaware of a similar study that we recently published on urban-tree cover, proximity to green space, and pregnancy outcomes in Portland, Oregon (Donovan et al., 2011). When we conducted our study, we didn't know about the parallel research being conducted in Spain. Unfortunately, this mutual ignorance meant that neither research team had the opportunity to interpret their results in light of the other's findings. The purpose of this correspondence is to briefly compare and contrast the methods and results of the two studies.
