A campaign launched last week by Population Service International is taking aim at cross-generational sex in Uganda in order to fight the spread of HIV to girls and women. HIV infection rates are four times as high among young women aged 15 to 24, a phenomenon health officials believe is because so many have sexual relationships with men at least 10 years their senior.

The program, which is set to take place in universities and about 50 of Uganda's secondary schools, will put an emphasis on empowering women to combat traditional practices that put them at risk for HIV and pregnancy. According to one study, 50 percent of Ugandan girls surveyed said that having cross-generational sex was normal, while 20 percent said they had done it.
