A new analysis from the U.S. Centers for Disease Control and Prevention finds that in 2010, the percentage of middle schools teaching about HIV, other sexually transmitted diseases, and pregnancy prevention was significantly lower in 11 states than it was two years earlier.
The findings come from a CDC analysis of 2008 and 2010 data for schools in 45 states.
The study also found that the percentage of schools teaching several condom-related topics in a required sexuality education course in grades 9, 10, 11, or 12 was significantly lower in eight states and higher in three.
The CDC said the findings indicate that schools made little progress in increasing the number of specific topics covered in sexuality education courses between 2008 and 2010.
