On Feb. 5, 2015, six doctors from UPHE with expertise in the affect of air pollution on pregnancy presented a 75 minute seminar at the Salt Lake City main library. You can listen to it here.
Air pollution causes morphologic changes in the placenta, narrowing blood vessels, and inhibiting blood transfer to the fetus.
Pregnant women exposed to more air pollution have multiple clinical adverse pregnancy outcomes including:
- Higher blood pressure
- Higher rates of pre-eclampsia
- Intrauterine growth retardation
- Still births
- Higher rates of gestational diabetes
- Premature births
- Premature rupture of membranes
- Low birth weight syndrome
- Neonates with smaller head circumference.
- Certain types of birth defects
Intrauterine inflammation, a significant risk factor for premature birth, is increased with air pollution exposure during pregnancy and even prior to conception.
Hourly increases in air pollution at the beginning of labor is associated with higher rates of premature birth
