Premature birth rate in U.S. increases for second year

For the second year in a row, the rate of preterm birth in the United States has increased. The premature birth rate went up from 9.6 percent of births in 2015 to 9.8 percent in 2016, giving the U.S. a “C” on the March of Dimes 2017 Premature Birth Report Card. The report card also shows that across the U.S., black women are 49 percent more likely to deliver preterm compared to white women. American Indian/Alaska Native women are 18 percent more likely to deliver preterm compared to white women.

More than 380,000 babies are born prematurely in the U.S. each year. An additional 8,000 babies were born prematurely in 2016 due to the increase in the preterm birth rate. Premature babies may have more health problems or need to stay in the hospital longer than babies born on time. Some of these babies also face long-term health effects, like problems that affect the brain, lungs, hearing or vision.

The Premature Birth Report Card provides rates and grades for all 50 states, plus the District of Columbia and Puerto Rico. Preterm birth rates worsened in 43 states, the District of Columbia and Puerto Rico. The rates stayed the same in three states (AL, AZ, WA), and improved in only four states (NE, NH, PA, WY).

  • Four states earned an “A” on the 2017 Premature Birth Report Card;
  • 13 states received a “B”;
  • 18 states got a “C”;
  • 11 states and the District of Columbia got a “D”;
  • 4 states and Puerto Rico received an “F.”

Among the 100 cities in the U.S. with the greatest number of births (latest data is for 2015), Irvine, California had the lowest rate of preterm birth (5.8 percent), and Cleveland, Ohio had the highest preterm birth rate (14.9 percent).

This year’s Report Card also includes a preterm birth disparity ratio. This measures the disparities in preterm birth rates across racial/ethnic groups in a geographic area. The disparity ratio shows that the differences in preterm birth rates among racial/ethnic groups are getting worse nationally and no state has shown improvement since the measurements started being recorded in 2010-2012.

There is no single cause of premature birth and therefore there is no simple solution. However, things like expanding research, increasing education, strengthening advocacy, and improving clinical care and community programs can all help. The March of Dimes continues to work towards giving every mom the opportunity to have a healthy pregnancy and every baby the chance to survive and thrive.
