ABSTRACT This article presents the results of a systematic review of the effectiveness and economic efficiency of individual-, group-, and community-level behavioral interventions intended to reduce the risk of acquiring sexually transmitted HIV in adult men who have sex with men (MSM). These results form the basis for recommendations by the Task Force on Community Preventive Services on the use of these interventions. Sexual risk behavior and condom use were the outcomes used to assess effectiveness. Intervention effectiveness on biological outcomes could not be assessed because too few studies of adequate quality have been published. The evidence found in our review shows that individual-level, group-level, and community-level HIV behavioral interventions are effective in reducing the odds of unprotected anal intercourse (range 27% to 43% decrease) and increasing the odds of condom use for the group-level approach (by 81%). The Task Force concluded that the findings are applicable to MSM aged 20 years or older, across a range of settings and populations, assuming that interventions are appropriately adapted to the needs and characteristics of the MSM population of interest. Based on findings from economic evaluation studies, the Task Force also concluded that group- and community-level HIV behavioral interventions for adult MSM are not only cost effective but also result in actual cost savings. Additional information about other effects, barriers to implementation, and research gaps is provided in this paper. The recommendations based on these systematic reviews are expected to serve the needs of researchers, planners, and other public health decision makers.

    ABSTRACT: The current study was conducted to examine the impact of mixing genders in HIV prevention intervention groups targeted toward HIV positive men and women. Men (N=310) and women (N=126) participated in a randomized clinical trial testing a behavioral risk reduction/ medication adherence intervention versus a general health control condition administered to small mixed gender groups. Gender composition of groups was examined in relation to participant group attendance and group satisfaction measures through correlations and logistic regression. Significant regression models were found for men in the risk reduction condition and for women in the general health condition, however, regression models were not significant for women in the risk reduction condition and men in the general health condition. The findings indicate that mixing genders in risk reduction interventions for men and women living with HIV/AIDS has no negative impact on women's group satisfaction and may positively impact men's group satisfaction. This calls into question the assumption that gender sensitive material will always make individuals uncomfortable within mixed gender groups. In practice, mixed gender intervention groups can be a helpful option for delivering programs to diverse populations especially when resources are limited within community-based services providers and AIDS service organizations. Although more thorough investigation is needed about the consequences and possible benefits of mixing genders within HIV prevention intervention groups, this study supports the idea that mixing genders may be a viable option, in practice, without sacrificing the integrity of the intervention.

    ABSTRACT: Background: Nationally, HIV incidence is rising rapidly among young (18–24 years old) men who have sex with men (YMSM). Knowledge of safer sex generally enhances self-efficacy for safer sex, an important predictor of safer-sex behaviors. Recent findings suggest that a strong negative social emotion (i.e., shame) increases YMSM’s sexual risk-taking. Unchangeable shame (e.g., desire for other men) might undermine (moderate) the link between knowledge and self-efficacy or between self-efficacy and unprotected anal intercourse (UAI): this may be less likely for changeable shame (e.g., shame about risky sexual behavior). Aim: To test the hypotheses that shame (i.e., sexual desire shame), but not shame about behavior (i.e., sexual behavior shame), will be positively related to UAI and will moderate the relationship between knowledge and self-efficacy and/or self-efficacy and UAI among YMSM. Method: In an online national study, 1177 young adult (18–24 years old) MSM reported one or more acts of UAI in the past 90 days with a casual partner. Eligible MSM filled out a survey in which they provided information about their knowledge of safer sex, self-efficacy for safer sex, reported levels of shame, and reported past 90-day UAI. Results: Sexual desire shame was negatively correlated with knowledge and self-efficacy and positively correlated with UAI, the pattern reversed for sexual behavior shame. Sexual desire shame significantly lowered the knowledge to self-efficacy and the self-efficacy to UAI links. Sexual behavior shame also reduced the link from knowledge to self-efficacy, but not the self-efficacy to UAI link. Conclusion: The present study shows that there are different types of shame that may produce different effects with different implications for health behavior. Sexual desire shame may better reflect an emotion that is activated prior to risky behavior (e.g., when men reflect upon or feel desire for another man). Sexual behavior shame, on the other hand, better reflects what has already happened, thus, those higher in knowledge, efficacy, and therefore, safer sex are least likely to experience shame behavior.

    ABSTRACT: The Avahan intervention promotes consistent (100%) condom use amongst men who have sex with men in southern India. We assessed how condom use varies with intervention exposure for men who have sex with men in Bangalore. Self-reported condom use and intervention exposure data were derived from a cross-sectional survey. Consistent condom use and condom use at last sex act with all, main, and casual male sex partners were assessed. Binary and continuous variables reflecting intervention exposure (including contact(s) with intervention staff, receiving condoms and seeing condom demonstrations) were used. Multivariable logistic regression was employed to assess the relationship between condom use with each type of partner and each exposure variable independently, controlling for socio-demographic and behavioural factors associated with condom use or intervention exposure. Condom use with all partners was higher among those who had ever been contacted by, received condoms from, or seen a condom demonstration by intervention staff (adjusted odds ratio >2, p < 0.02 for all). Consistent condom use with all types of partner increased with the number of condom demonstrations seen in the last month (adjusted odds ratio = 2.1 per demonstration, p < 0.025), while condom use at last sex act with a casual (but not main) partner increased with the number of condoms received from the intervention (adjusted odds ratio = 1.4 per condom, p = 0.04). Direct contact with Avahan program staff is associated with increased reported condom use among men who have sex with men in Bangalore. Reported consistent condom use and condom use at last sex act are associated with contacts involving demonstrations of correct condom use, and with receiving condoms, respectively.
