Associations of maternal exposure to fine particulate matter with preterm and early-term birth in high-risk pregnant women.

ABSTRACT:

Background

Environmental pollution is a risk factor for adverse birth outcomes, especially preterm birth (PTB) and early-term birth (ETB). It has been revealed that exposure to fine particulate matter (PM_2.5) during pregnancy increase the prevalence of PTB. However, the relationship between PM_2.5 exposure and ETB has not been elucidated. In high-risk pregnancies, whether PM_2.5 exposure will bring higher risk of PTB and ETB than in normal pregnancies is still unclear, and the susceptible exposure window is obscure. Therefore, it is worthy of assessing the risk on PTB and ETB and identifying the susceptible exposure windows of PM_2.5 exposure in high-risk pregnant women.
