The rate at which teenage girls in the United States are having babies has risen for a second year in a row, government statistics show, putting one of the nation's most successful social and public health campaigns in jeopardy.
Teen births in the District, Maryland and Virginia mirror the national trend, the numbers show, and local health experts say they are alarmed by the shift.
Nationally, the birthrate among 15-to-19-year-olds rose 1.4 percent from 2006 to 2007, continuing a climb that began a year earlier. The rate jumped 3.4 percent from 2005 to 2006, reversing what had been a 14-year decline.
Although researchers will have to wait at least another year to see whether a clear trend emerges, the two consecutive increases signal that the long national campaign to reduce teen pregnancies may have stalled or even reversed.
"We've now had two years of increases," said Stephanie J. Ventura of the National Center for Health Statistics, which issued the report yesterday. "We may have reached a tipping point. It's hard to know where it's going to go from here."
The reasons for the increase remain unclear, although experts speculated that it could be a result of growing complacency about AIDS and teen pregnancy, among other factors. The rise may also reflect a broader trend that affects all age groups, because birthrates have also increased among women in their 20s, 30s and 40s and older unmarried women.
