Teen pregnancy rates in the U.S. rose for the time in more than a decade, according to a new report by the Guttmacher Institute.

The report by the Planned Parenthood think tank shows 7 percent of all teenage girls got pregnant in 2006. Also, the overall teen pregnancy rate was up 3 percent. It is the first time in over 10 years that the rate actually increased.

The rate of teen abortions also rose 1 percent from 2005 to 2006.

"It is a tragedy that after a decade of progress in reducing the rate of teenage pregnancy we are witnessing a substantial increase in the number of teens who are getting pregnant," the Planned Parenthood officials said in a prepared statement.

The study's finding were based on data from National Center for Health Statistics of the U.S. Department of Health and Human Services, the Guttmacher Institute, the U.S. Centers for Disease Control and Prevention and the Population Estimates Program of the U.S. Bureau of the Census in collaboration with NCHS.
