There's been little progress in recent years in boosting the number of American secondary schools that teach students how to prevent pregnancy and protect themselves against HIV and other sexually transmitted diseases (STDs).
That's the finding from researchers at the U.S. Centers for Disease Control and Prevention who analyzed 2008 and 2010 data from 45 states taking part in biennial surveys of school health practices.
The surveys assessed the percentage of schools in each state that teach specific topics related to HIV, STD and pregnancy prevention. The topics differ in middle schools and high schools, but generally include basic information on the transmission and diagnosis of HIV and other STDs, as well as pregnancy risk reduction. Condom use is one of the topics that's covered only in high schools, the CDC said.
