New research from Curtin University reveals that exposure to outdoor air pollution and extreme temperatures during pregnancy may increase the risk of prolonged pregnancies, offering fresh insights into the effects of climate change on maternal health.
The study, which analyzed nearly 400,000 births in Western Australia, found that higher exposure to fine particulate air pollution (PM2.5) and biothermal stress a combination of temperature, humidity, wind speed, and human physiology was linked to pregnancies lasting beyond 41 weeks.
Dr. Sylvester Dodzi Nyadanu, the study’s lead author from Curtin’s School of Population Health, explained that while preterm births have been studied extensively, this is the first research to explore the impact of environmental factors on prolonged pregnancies.
“Prolonged pregnancy can pose serious risks for both mothers and babies, such as the need for medical interventions, increased chances of stillbirth, birth complications, child mortality, and early behavioral or emotional problems,” Dr. Nyadanu said.
The study found that the risk was especially high for first-time mothers, women over 35, those living in urban areas, and those with complicated pregnancies. Dr. Nyadanu highlighted how climate-related stressors can disrupt maternal endocrine and inflammatory activities late in pregnancy, potentially leading to longer gestation.
With climate change driving more extreme weather events and deteriorating air quality, Dr. Nyadanu urged healthcare providers, policymakers, and vulnerable groups to consider these environmental factors when assessing pregnancy risks. He emphasized the importance of better air quality regulations and public health initiatives to protect pregnant women and children from climate-related health issues.
