Protecting pregnant women from air pollution may improve the birth weight of their babies, a new study suggests. This is especially important for stressed-out mothers who live in neighborhoods burdened by poor air quality. A mother-to-be’s exposure to both air pollution and psychological stress during early to mid-pregnancy can disrupt delicate fetal growth, according to the study authors. “Although air pollution has a harmful effect on many different populations, our study identified the effects on expectant mothers who are already most vulnerable,” said study co-author Zhongzheng Niu. “The addition of high perceived stress is another factor contributing to this issue. We already know air pollution is linked to low birth weight and future disease risk. Protecting pregnant women from these risks would ultimately protect future generations,” added Niu, a postdoctoral scholar and research associate at the University of Southern California (USC) Keck School of Medicine. Having a low birth weight increases an infant’s risks of other health issues, including breathing problems, bleeding in the brain, jaundice, infections and even death. It may also increase long-term disease risks, such as diabetes, heart disease, high blood pressure, intellectual and developmental disabilities, and obesity, the research team noted in a university news release. For the study, the researchers analyzed the issue using data from 628 predominantly low-income Hispanic women who were pregnant between 2015 and 2021. The women… read on > read on >
