Building upon earlier work that has examined the impact of air pollution on pregnancy, Kyung Sung, Dr. Sherin Devaskar and Dr. Carla Janzen, along with Dr. Beate Ritz (not pictured), will study how exposure to pollution affects the placenta.

The National Institutes of Health has awarded UCLA a $4.2 million grant to study how environmental pollution negatively affects how the placenta develops in pregnant women, ultimately contributing to poor pregnancy outcomes.
Dr. Sherin Devaskar, the Mattel Executive Endowed Chair of the department of pediatrics at Mattel Children’s Hospital UCLA, will lead a team of researchers that will build upon earlier work that has examined the impact of air pollution on pregnancy.
The placenta is a critical organ that shuttles blood, oxygen, and nutrients from mother to fetus and clears harmful waste like carbon dioxide. It also produces hormones to help sustain the pregnancy and regulate the immune system so that mother and fetus can coexist. Many problems of pregnancy — such as preeclampsia, preterm birth, and even stillbirth — can occur because of problems with the placenta.

“The placenta has always been the forgotten organ due to its transient existence but, despite that temporary role, it is a critical organ that connects mother and child,” Devaskar said. “It is also the starting point in determining the health of a child.”
The early stages of pregnancy are a particularly vulnerable time because the fetus is developing and a mother’s exposure to air pollution may alter the way that the placenta forms and how it functions throughout the rest of pregnancy. “Any alterations in either the structure or function of the placenta will interfere with the health and well-being of mother and child,” Devaskar said.

Previous studies at UCLA have shown that exposure to significant air pollution from traffic, air toxins from industry, or other environmental toxins can result in poor birth outcomes, including premature birth and intra-uterine growth restriction, which have both been investigated previously by this team of researchers. These conditions are strongly correlated with infant morbidity and in addition, can lead to a host of adult diseases that range from diabetes and obesity and coronary artery disease, to cognitive disabilities and cancer.
Understanding the mechanism of environmental pollution on the placenta will help clinicians recognize placental insufficiency early on, and allow for preventive and therapeutic strategies before detrimental consequences occur, Devaskar said. The study, she noted, could help ensure safe and healthy pregnancies for women.
