McCabe said African-American women are the most likely to have premature babies. Native Americans and Hispanics also have higher rates than whites and Asian-Americans.
"It’s an issue of access to prenatal care, preconception care and chronic conditions in that population," McCabe said.
McCabe added that a group of Somali immigrants in Ohio does not have the same high rates of preterm births. The March of Dimes is studying that group to see what the differences are.
