Rossner et al. (2011) studied associations between the levels of 8-oxodG in placental DNA, exposure to air pollutants during pregnancy, genetic polymorphisms in 94 selected genes, and pregnancy outcomes in 891 newborns who were born between the years 1994–1998. Levels of 8-oxodG in placental DNA were associated with the risk of IUGR as well as LBW. Newborn's sex, gestational age, maternal smoking, and genetic polymorphisms in the promoter region of the MBL2 gene were associated with LBW incidence.
