Dallas leads the nation in the percentage of teen births that aren't the mother's first delivery, a nonpartisan national research group finds in a new report.
Dallas had the highest percentage of teen births that are repeat births - 28 percent - among 73 major U.S. cities in 2006, the latest year for which city-level data are available.
Texas has the highest repeat rate of any state - 23 percent of teen births. And five of the 15 worst-ranked cities are in Texas, according to the group Child Trends, in a report to be released Wednesday.
"That's not where we want to be, for sure," said Sarah Wheat, a spokeswoman for Planned Parenthood in Austin.
Texas had the highest repeat rate of any state for the sixth consecutive year.
