Researchers have discovered a new danger for pregnant women: fetuses may struggle to breathe even in the womb.

In the later stages of pregnancy, the environment surrounding the expectant mother plays a crucial role in the health of her newborn. A recent study has revealed a significant link between air pollution exposure during the last month of pregnancy and an increased likelihood of hospitalization in the neonatal intensive care unit, as reported by HealthDay.

The research, led by Dr. Johan V.A. Fiore, a researcher at the University of Buffalo, meticulously analyzed birth records from 2018 and satellite data on air pollution across the United States. The findings, published in the journal Scientific Reports, indicate that even a slight rise in pollutant levels in the air during the final month of pregnancy can substantially heighten the risk of complications for newborns.

Specifically, the study found that increased exposure to nitrogen dioxide (NO2), a byproduct of fossil fuel combustion in vehicles and power plants, is associated with a 30-35% increase in the likelihood of neonatal intensive care unit hospitalization. Similarly, exposure to fine particulate matter (PM2.5), found in vehicle exhaust and wildfire smoke, was linked to an 11-22% increased risk of hospitalization in the intensive care unit. These microscopic pollutants can penetrate deep into the respiratory system, potentially crossing the placenta and impacting fetal development.

Dr. Fiore emphasized the critical nature of the final weeks of pregnancy, stating: "Our findings indicate the serious impact of air pollution in the last weeks of pregnancy — a time of increased vulnerability for the fetus." Scientists recommend that expectant mothers minimize exposure to polluted environments, especially during this sensitive period.

Although the study did not establish a direct causal relationship, it urged authorities to recognize the importance of continuous efforts to improve air quality. Dr. Fiore noted: "Our results highlight the urgent need to reduce air pollution and enhance its quality." Such measures could play a vital role in safeguarding the health of mothers and newborns from serious consequences.

Previous studies have linked prenatal exposure to air pollution with various adverse outcomes, including congenital defects, preterm births, and altered fetal growth. This research adds to the growing body of evidence, underscoring the tangible risks associated with environmental pollution during pregnancy.
