Pollution exposure linked to smaller newborns

Exposure to air pollution during pregnancy has been linked to smaller newborns.

US scientists have found a link between pollution exposure during early pregnancy and low birthweight newborns.

The researchers say that mums exposed to air pollution – tiny airborne particles PM2.5 and PM10, and to nitrogen dioxide – were significantly more likely to have lighter babies.

They say that the link was even stronger for women who reported higher levels of stress during pregnancy, and those living in neighbourhoods with high levels of environmental pollution.

The study is an observational study so cannot directly prove that air pollution causes lower birthweight babies. However, the researchers suggest that based on these findings, it’s sensible to protect pregnant women from air pollution as much as possible.
