Environmental noise pollution and risk of preeclampsia

Highlights: • Noise exposure is a risk factor for cardiovascular disease in adult populations. • We studied the association between noise and preeclampsia in pregnancy. • Exposure to environmental noise was associated with a greater risk of preeclampsia. • The associations were stronger for severe and early onset preeclampsia. • Environmental noise may be a novel risk factor for preeclampsia in pregnant women. Environmental noise exposure is associated with a greater risk of hypertension, but the link with preeclampsia, a hypertensive disorder of pregnancy, is unclear.
