Lowe J, et al. - The purpose of this research was to investigate if the increased respiratory symptoms associated with altered fetal growth and infant weight gain were mediated by early factors. The antenatal and postnatal growth rates were discovered to be crucial for future respiratory health in preterm-born children. Their effects could be mediated via modifiable factors. An improvement could be achieved in the outcomes by minimizing exposure to environmental pollutants, especially maternal tobacco smoking.
