Abstract
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 (PM2.5) was assigned to residential address at delivery using a chemical transport model. Maternal, meteorological and temporal variables were included in final log-binomial regression models.
Results: 3612 singleton pregnancies were included in the analysis; 766 were exposed to the smoke event. Average maternal PM2.5 exposure was 4.4 μg/m3 (SD 7.7; IQR 2.12). Average peak PM2.5 exposure was 44.9 μg/m3 (SD 57.1; IQR 35.0). An interquartile range increase in peak PM2.5 was associated with a 16% increased likelihood of gestational diabetes mellitus (95%CI 1.09, 1.22; <0.0001). Whereas, an interquartile range increase in average PM2.5 was associated with a 7% increased likelihood of gestational diabetes mellitus (95%CI 1.03, 1.10; <0.0001). Second trimester exposure was of critical importance. No association for hypertensive disorders or abnormal placentation was observed.
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.
