PURPOSE:
As climate change accelerates the frequency and intensity of wildfires worldwide, pregnant people are being increasingly exposed to hazardous smoke and air pollution. This presentation explores the complex and growing body of evidence linking wildfire smoke exposure during pregnancy to adverse health outcomes for both pregnant patients and their fetuses. We will discuss the composition of wildfire smoke, its absorption by pregnant patients, and its ability to cross the placenta. Global epidemiological data demonstrate a consistent association between wildfire exposure and heightened risks of preterm birth, hypertensive disorders of pregnancy, placental abruption, congenital anomalies, and neonatal respiratory compromise. We will also highlight recent research connecting in-utero exposure to long-term neurodevelopmental effects and an increased incidence of postpartum depression. Inequities in exposure and protective resources, such as access to masks, air purifiers and the ability to evacuate, exacerbate vulnerability among marginalized populations.

DISCUSSION:
Midwives are uniquely positioned to educate patients, stakeholders, legislators and healthcare providers about the risks of wildfire exposure and ways to mitigate these risks. This presentation will offer actionable, low-tech interventions to mitigate risk, guidance for patient counseling, and a call to incorporate climate literacy into reproductive health education and practice.

EVIDENCE WHERE RELEVANT:
Please see references in the attached Powerpoint Presentation.

KEY MESSAGE:
Wildfire smoke, intensified by climate change, poses serious risks to pregnant individuals and their fetuses, including increased rates of preterm birth, hypertensive disorders, low birth weight, and postpartum depression. These risks are not equally distributed—socioeconomic and racial disparities amplify exposure and reduce access to protective measures. Midwives must recognize pregnancy as a key vulnerability in climate-related health and take actionable steps to reduce exposure, counsel patients, and advocate for systemic change.
