Study links PM2.5 pollution with millions of preterm births globally

20 Feb 2017   Air Quality

A new study, led by a team from The Stockholm Environment Institute (SEI) at the University of York, has found that in 2010, about 2.7 million preterm births globally—or 18% of all pre-term births—were associated with outdoor exposure to fine particulate matter (PM 2.5 ).The open-access study is published in the journal Environment International. There are many known risk factors for preterm birth—from the mother’s age, to illness, to poverty and other social factors. Recent research has suggested that exposure to air pollution could also be a risk factor. The researchers combined national, population-weighted, annual average ambient PM 2.5 concentration, preterm birth rate and number of livebirths to calculate the number of PM 2.5 -associated preterm births in 2010 for 183 countries. Uncertainty was quantified using Monte-Carlo simulations, and analyses were undertaken […]
