Preterm Births, 2019

Preterm birth and low birthweight can be associated with developmental and physical challenges for newborns that can have lasting effects on their health and well-being. Nationally, more than 10 percent of births were considered preterm in 2019. Not all mothers have equal access to prenatal care and pregnancy supports, which—in some cases—can help prevent preterm births. Structural racism in the health care field can drive differences in access to prenatal care across racial and ethnic groups. Experiencing racism and associated trauma can also directly affect health outcomes and drive inequities across groups. The table below presents data disaggregated by race and ethnicity to help us identify inequities and work toward solutions that promote equity.

Home Visiting as Part of the Solution. Home visiting is associated with lower likelihood of preterm birth among participating mothers compared to nonparticipating mothers. Home visitors help expectant mothers access prenatal care and encourage healthy behaviors during pregnancy, which can help support full-term pregnancy.
