Description
Yuhong Hu and colleagues track mood across pregnancy against air pollution exposure in a 2026 cohort study. Low mood in pregnancy follows varied paths. Dirty air has been tied to depression risk, yet little was known about whether exposure before or early in pregnancy steers which path a woman follows. The team followed 542 mostly low-income Hispanic and Latina participants in the MADRES cohort, scoring mood in each trimester and estimating home exposure to fine particles, coarse particles, nitrogen dioxide and ozone.
Four mood paths emerged, from steady low symptoms in 43.4 percent to moderate-to-high symptoms in 7.4 percent. Higher early-pregnancy nitrogen dioxide raised the relative risk of the worst path versus the steadiest path by 3.82 times, with smaller rises for fine and coarse particles. The link is observational, but it points to cleaner air in early pregnancy as one more lever for protecting maternal mood.
