Efficacy of HIV/STI behavioral interventions for heterosexual African American men in the United States: a meta-analysis
Henny KD , Crepaz N , Lyles CM , Marshall KJ , Aupont LW , Jacobs ED , Liau A , Rama S , Kay LS , Willis LA , Charania MR . AIDS Behav 2012 16 (5) 1092-114 This meta-analysis estimates the overall efficacy of HIV prevention interventions to reduce HIV sexual risk behaviors and sexually transmitted infections (STIs) among heterosexual African American men. A comprehensive search of the literature published during 1988-2008 yielded 44 relevant studies. Interventions significantly reduced HIV sexual risk behaviors and STIs. The stratified analysis for HIV sexual risk behaviors indicated that interventions were efficacious for studies specifically targeting African American men and men with incarceration history. In addition, interventions that had provision/referral of medical services, male facilitators, shorter follow-up periods, or emphasized the importance of protecting family and significant others were associated with reductions in HIV sexual risk behaviors. Meta-regression analyses indicated that the most robust intervention component is the provision/referral of medical services. Findings indicate that HIV interventions for heterosexual African American men might be more efficacious if they incorporated a range of health care services rather than HIV/STI-related services alone. |
Prevalence of unprotected anal intercourse among HIV-diagnosed MSM in the United States: a meta-analysis
Crepaz N , Marks G , Liau A , Mullins MM , Aupont LW , Marshall KJ , Jacobs ED , Wolitski RJ , Hiv Aids Prevention Research Synthesis Team . AIDS 2009 23 (13) 1617-29 OBJECTIVE: To integrate the empirical findings on the prevalence of unprotected anal intercourse (UAI) among HIV-diagnosed men who have sex with men (MSM) in the United States. METHODS: Comprehensively searching MEDLINE, EMBASE, PsycINFO (2000-2007), hand searching bibliographic lists, and contacting researchers. Thirty US studies (n = 18,121) met selection criteria. Analyses were conducted using random-effects models and meta-regression. RESULTS: The prevalence of UAI was considerably higher with HIV-seropositive partners (30%; 95% confidence interval 25-36) than with serostatus unknown (16%; 95% confidence interval 13-21) or HIV-seronegative partners (13%; 95% confidence interval 10-16). The prevalence of UAI with either a serostatus unknown or HIV-seronegative partner was 26%. The UAI prevalence did not differ by the length of the behavioral recall window but did vary by the type of anal intercourse (insertive vs. receptive). Studies with the following features had a lower UAI prevalence: recruiting participants before 2000, MSM of color being the majority of study sample, recruiting participants from medical settings, using random or systematic sampling methods, and having interviewers administer the questionnaire. Being on antiretroviral therapy, having an undetectable viral load, and reporting more than 90% medication adherence were not associated with UAI. CONCLUSION: Most HIV-diagnosed MSM protect partners during sexual activity, but a sizeable percentage continues to engage in sexual behaviors that place others at risk for HIV infection and place themselves at risk for other sexually transmitted infections. Prevention with positives programs continues to be urgently needed for MSM in the United States. |
The efficacy of HIV/STI behavioral interventions for african american females in the United States: A meta-analysis
Crepaz N , Marshall KJ , Aupont LW , Jacobs ED , Mizuno Y , Kay LS , Jones P , McCree DH , O'Leary A . Am J Public Health 2009 99 (11) 2069-78 OBJECTIVES: We evaluated the efficacy of HIV behavioral interventions for African American females in the United States, and we identified factors associated with intervention efficacy. METHODS: We conducted a comprehensive literature review covering studies published from January 1988 to June 2007, which yielded 37 relevant studies. Data were analyzed using mixed-effects models and meta-regression. RESULTS: Overall, behavioral interventions had a significant impact on reductions in HIV-risk sex behaviors (odds ratio [OR]=0.63; 95% confidence interval [CI]=0.54, 0.75; n=11239; Cochrane Q32=84.73; P<.001) and sexually transmitted infections (STIs; OR=0.81; 95% CI=0.67, 0.98; n=8760; Cochrane Q16=22.77; P=.12). Greater intervention efficacy was observed in studies that specifically targeted African American females used gender- or culture-specific materials, used female deliverers, addressed empowerment issues, provided skills training in condom use and negotiation of safer sex, and used role-playing to teach negotiation skills. CONCLUSIONS: Behavioral interventions are efficacious at preventing HIV and STIs among African American females. More research is needed to examine the potential contribution of prevention strategies that attend to community-level and structural-level factors affecting HIV infection and transmission in this population. |
