In-Womb Air Pollution Exposure May Up Blood Pressure in Childhood

Pollution may affect fetal growth and increase future risks for high blood pressure, as per the study.

Exposure of babies to high levels of air pollution in the womb may increase the risk of elevated blood pressure in childhood, according to a new study.

Fine particulate matter of 2.5 microns or less (PM2.5) is a form of air pollution produced by motor vehicles and the burning of oil, coal and biomass. It has been shown to enter the circulatory system and negatively affect human health.

The findings suggest that children exposed to higher levels of ambient fine-particulate pollution in the womb during the third trimester were 61% more likely to have elevated systolic in childhood compared to those exposed to the lowest level.
