Air Pollution During Pregnancy Linked to Increased Postpartum Depression Risk
2025-03-28
A new study reveals a significant link between exposure to high levels of nitrogen dioxide (NO2) and PM10 particulate matter during pregnancy and an increased risk of postpartum depression. Researchers at the University of California followed 361 low-income Hispanic/Latina women in Los Angeles for three years. Women exposed to high levels of NO2 or PM10 during their second trimester were nearly four times more likely to develop postpartum depression compared to those with lower exposure. The study highlights the importance of reducing air pollution exposure during pregnancy, especially during the second trimester, and underscores the need for mitigating traffic emissions.
