To assess the effects of HIV/AIDS and sexuality education on young people's sexual behavior; a comprehensive literature review was commissioned by the Office of Intervention Development and Support within the World Health Organization's Global Programme on AIDS. Fifty-two reports were reviewed. Of 47 studies that evaluated interventions, 25 reported that HP//AIDS and sexuality education neither increased nor decreased sexual activity and attendant rates ofpregnancy and STDs. Seventeen reported that HIV and/or sexuality education delayed the onset of sexual activity, reduced the number of sexual partners, or reduced unplanned pregnancy and STD rates. Only three studies found increases in sexual behavior associated with sexuality education. Hence, little evidence was found to support the contention that sex and/or HIV education promote promiscuity. The interpretative value of this research often was compromised, however, because of inadequacies in study design, analytic techniques, outcome indicators, and reporting of statistics.
Uganda is one of only two countries in the world that has successfully reversed the course of its HIV epidemic. There remains much controversy about how Uganda's HIV prevalence declined in the 1990s. This article describes the prevention programs and activities that were implemented in Uganda during critical years in its HIV epidemic, 1987 to 1994. Multiple resources were aggregated to fuel HV pre-
Inquiry into the determinants of risk-related sexual behavior is important for the development of interventions to reduce the incidence of new cases of human immunodeficiency virus infection. Recent social and behavioral research has revealed much about the individual and social factors influencing risk-taking. Findings from these studies have been important in the development of new educational and community-based interventions for communities at risk in the developed and developing worlds.
To determine the prevalence of Mycobacterium tuberculosis infection and the incidence of tuberculosis in HIV-infected and uninfected urban Rwandan women, 460 HIV-positive and 998 HIV-negative childbearing women were recruited from pediatric and prenatal care clinics and were enrolled in a prospective study in 1988 and followed for 2 yr. Tuberculin testing was administered 12 to 18 months after enrollment. Fifty-three percent of HIV-negative women had positive tuberculin tests (induration > or = 10 mm), with higher rates among older women and among women who had received BCG vaccine. Only 21% of HIV-positive women had positive tuberculin tests, with no relationship to BCG vaccine. Follow-up was available for 93% of subjects. Tuberculosis was diagnosed in 20 HIV-positive women and in two HIV-negative women. Features associated with an increased risk of tuberculosis among HIV-positive women included: age > or = 30, body mass index in the lowest quartile, low income, erythrocyte sedimentation rate > 75, positive tuberculin test, and chronic cough, chronic fever, and weight loss. Among Rwandan women who are infected with HIV, approximately half of those who are infected with M. tuberculosis do not have positive tuberculin tests. The rate ratio for development of tuberculosis among HIV-positive women was 22 (95% CI, 5 to 92). New algorithms are needed to improve the early detection of tuberculosis among HIV-positive patients in Africa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
