Efforts to prevent teen pregnancies appear to be paying off. Fewer adolescent girls in the United States are giving birth, a trend the CDC has linked with a decline in preterm birth rates.

Nationally, preterm births have declined by 8.4%, from 10.4% of live births in 2007 to 9.5% in 2014, according to a recent CDC analysis. Although women of all ages had fewer premature babies during those years, a 39.5% decline in teen births and an 11.7% decrease in births to women aged 20 to 24 years had the biggest impact on the overall reduction in preterm births. An increase in births to mothers aged 30 years or older didn’t affect the overall decrease in preterm births.
