Exposure to PM2.5 May Be Associated with Adverse Birth Outcomes: Study Finds
Advertisement
For pregnant women, exposure to fine particulate air pollution (PM2.5) was associated with altered immune responses that can lead to adverse birth outcomes, according to a new study led by Harvard T.H. Chan School of Public Health. The study was published in Science Advances.
Key points from the study are:
Exposure to PM2.5 was associated with higher levels of inflammation among pregnant women, potentially leading to adverse birth outcomes.
Study examined PM2.5 and maternal and fetal health on a single-cell level, using an innovative technology to detect how pollution modified the DNA within individual cells.
Findings provide new understanding of the biological pathways through which air pollution affects pregnancy and birth outcomes, and further highlight the importance of policy and clinical interventions to limit air pollution exposure for pregnant women.
