Ozone Exposure During Pregnancy and Risk of Gestational Hypertension or Preeclampsia in China

Abstract

Results of this study showed an association between increased gestational hypertension risk and O3 exposure during the first trimester. Furthermore, gestational weeks 1 to 9 were identified as the window of susceptibility for O3 exposure and elevated gestational hypertension risk. Sustainable O3 control is needed to reduce the disease burden of gestational hypertension.
