Environmental pollution and risk of preterm birth
There is an association between environmental pollution and preterm births and a new study explored the effect of different types of pollution in a large cohort of pregnant women.
Environmental pollution exposure during pregnancy has been identified as a risk factor for preterm birth, also known as premature birth. Many studies have shown that prenatal exposure to air pollution, contaminated water, pesticides and other environmental toxins can increase the risk of a preterm birth.
This study analysed 53,843 births in Fresno County, California, an area with high levels of environmental pollution and a high rate of preterm births. The risk of preterm birth was associated with exposure to high levels of pollution including polluted drinking water and the association was stronger in areas of low socioeconomic status.
