Prenatal greenness exposure and the decreased risk of low birthweight and small for gestational age: modification and mediation effects of air pollution

This study provided national evidence for greater health benefits of greenness in alleviating LBW and SGA risks among pregnant women being exposed to higher PM_2.5 and O₃ pollution levels. Reduced PM_2.5 and O₃ may partially mediate the association of greenspace exposure with fetal growth.
