This news is based on the following article: Hehua Z, Qing C, Shanyan G, Qijun W, Yuhong Z. The impact of prenatal exposure to air pollution on childhood wheezing and asthma: a systematic review. Environmental Research 2017 ; 159 : 519–530. doi : 10.1016/j.envres.2017.08.038
The current epidemiologic literature suggests an association between prenatal exposure to certain pollutants (nitrogen dioxide, PM10, and sulfur dioxide) and the development of asthma in childhood. Further high quality studies are needed to supplement the literature. The authors of this article underline the need for more harmonized methods.
