Résumé
In 2014, the Hazelwood coal mine fire was an unprecedented event that resulted in a six-week period of poor air quality in the Latrobe Valley in regional Australia. We aimed to determine whether maternal exposure to fine particulate matter in coal mine fire smoke was associated with selected obstetric complications, including gestational diabetes mellitus, hypertensive disorders of pregnancy and abnormal placentation. We defined a complete cohort of pregnant women with births >20 weeks in the Latrobe Valley from March 1, 2012-Dec 31, 2015 utilising administrative perinatal data. Average and peak fine particulate matter (PM 3612 singleton pregnancies were included in the analysis; 766 were exposed to the smoke event. Average maternal PM this is the first study to examine obstetric complications relating to a discrete smoke event. These findings may guide the public health response to future similar events.

BACKGROUND
In 2014, the Hazelwood coal mine fire was an unprecedented event that resulted in a six-week period of poor air quality in the Latrobe Valley in regional Australia. We aimed to determine whether maternal exposure to fine particulate matter in coal mine fire smoke was associated with selected obstetric complications, including gestational diabetes mellitus, hypertensive disorders of pregnancy and abnormal placentation.
METHODS
We defined a complete cohort of pregnant women with births >20 weeks in the Latrobe Valley from March 1, 2012-Dec 31, 2015 utilising administrative perinatal data. Average and peak fine particulate matter (PM
RESULTS
3612 singleton pregnancies were included in the analysis; 766 were exposed to the smoke event. Average maternal PM
CONCLUSION
this is the first study to examine obstetric complications relating to a discrete smoke event. These findings may guide the public health response to future similar events.
