This study conducted during 1999-2002 is concentrated on the young people in rural Mwanza Region, northern Tanzania, on the southern shore of Lake Victoria. The area is occupied mostly by Sukuma and smaller ethnic groups, all of whom speak Swahili. Only 7 percent of Tanzania's school-age population was enrolled in secondary education... The vast majority of young women was sexually active and in relations--fleeting as they may have been--with men who supplied gifts or direct payment for sex. Only 12 percent of 15-19-year-old women reported ever having used contraceptive methods, mostly condoms. Plummer and Wight (both, UK Medical Research Council) suggest that (illegal) abortion was practiced widely. Counseling and behavior modification were most active in the realm of sexually transmitted infections. Many villagers in this study believed "real" AIDS was sexually transmitted, but also believed that a separate AIDS-mimicking illness was caused by witchcraft. Restrictive norms, rather than the threat of HIV infection, constrained sexual activity. The inclusion of detailed case studies makes this study personal and supplies depth. There is a Swahili and Sukuma glossary. Summing Up: Recommended. Graduate students, faculty, professionals.
