Changes in HIV/AIDS/STI knowledge, attitudes, and behaviours among the youth in Port Loko, Sierra Leone.

Sierra Leone suffered from 11 years of civil war (1991-2002) resulting in tens of thousands of deaths and mutilations and massive population displacement. In 2001, ARC International, Sierra Leone, conducted a baseline survey of 244 female youth and 293 male youth on knowledge, attitudes, and behaviours around HIV/AIDS and STIs in Port Loko. In 2003, following 2 years of HIV prevention activities, a comparable post-intervention survey of 250 female and 299 male youth was performed.
