Interventions to modify sexual risk behaviors for preventing HIV infection in men who have sex with men

摘要: Background MSM remain at great risk for HIV infection. Program planners and policy makers need descriptions of interventions quantitative estimates intervention effects to make informed decisions concerning prevention efforts. Objectives 1. To locate describe outcome studies evaluating the behavioral social targeting MSM. 2. summarize effectiveness these among 3. stratify results by characteristics participants. 4. identify gaps indicate future research, policy, practice needs. Search strategy We searched electronic databases (MedLine, PsycInfo, etc.); several current journals (e.g., AIDS, AIDS Behavior, Education Prevention, American Journal Public Health, Acquired Immune Deficiency Syndromes, manuscripts submitted researchers; bibliographies relevant articles; other published reviews, unpublished reports from 1988 through 1997. Selection criteria Studies were considered in scope if they examined reduce or STD transmission. reviewed relevance (measurement least one a list biologic outcomes, e.g., unprotected sex incidence infections) methodologic rigor (randomized controlled trials certain strong quasi-experimental designs with comparison groups). Data collection analysis As June 1998 we had identified 13 eligible studies. Twelve (7 small group interventions, 3 community-level 2 individual level interventions) reported on sex. Because few condom use (3 studies), number partners without regard (4 (1 study which no infections occurred) do not address outcomes this time. present those analyses can be performed Cochrane RevMan software, followed more complete that permit inclusion studies, adjustment baseline conditions, calculation effect sizes wider variety statistics an F-statistic one-way ANOVA), simultaneous meta-analysis continuous dichotomous (Johnson 2002b). translate summary reduction behavior based background prevalence Finally provide stratified content (interpersonal skills addressed not), format (community vs individual) mean age participants (23 31 vs. 32 36). Main A measure reducing was favorable (odds ratio = 0.73) statistically significant (CI, 0.60 0.88), corresponding 23% proportion men engaging Effects homogeneous but slightly served populations their 20s rather than 30s, promoted interpersonal skills. Reviewer's conclusions These demonstrate promote Yet given epidemiology Pattern I countries, rigorous population is striking. Many evaluations efforts are needed ascertain confidence specific components, characteristics, features.
