While teen births have declined over the past 20 years, nearly one in five teen births is a repeat birth, according to a report released yesterday by the Centers for Disease Control and Prevention. More than 365,000 teens, aged 15 to 19, gave birth in 2010, and about 18% of those were repeat births – a second or more pregnancy resulting in a live birth before the age of 20. “Teen birth rates in the United States have declined to a record low, which is good news,” said CDC Director Tom Frieden, M.D. “But rates are still far too high. Repeat births can negatively impact the mother’s education and job opportunities as well as the health of the next generation. Teens, parents, health care providers, and others need to do much more to reduce unintended pregnancies.” The report says that repeat teen births decreased by more than 6% between 2007 and 2010, and there are substantial differences based on race, ethnicity and geography.
