Overview: As of 2005, Kenya had one of the largest HIV-infected populations in the world—approximately 7 percent of Kenyans were infected. To test the impact of information on teenagers’ sexual decisions, a “Relative Risk Information Campaign” was conducted in 71 schools to give students information about the distribution of HIV infection rates by age and gender groups and discuss the role of cross-generational sex in the spread of HIV. The information led to a significant reduction in unwanted teenage childbearing with older partners, suggesting a decrease in unprotected sex with older partners.
Findings: As a result of this intervention, the incidence of childbearing was reduced by 28 percent (from 5.4 percent of girls getting pregnant within a year, to 3.9 percent). This suggests that the intervention reduced the likelihood that girls engage in unsafe sex. Specifically, the intervention seems to have reduced unsafe cross-generational sex: the rate of childbearing with men five or more years older fell by 61 percent, with no offsetting increase in childbearing with adolescent partners.
