ABSTRACT Population-based HIV incidence, prevalence, and mortality rates among men who have sex with men (MSM) have been unavailable, limiting assessment of racial/ethnic disparities and epidemic dynamics.
Using estimated numbers of MSM aged >or=18 years by race/ethnicity as denominators, from models in our prior work, we estimated MSM HIV prevalence and mortality rates for 2006-2007 and HIV incidence rates for 2006 in Florida.
Overall, the estimated MSM HIV prevalence rates per 100,000 MSM were 7354.8 (2006), and 7758.3 (2007). With white MSM as the referent, MSM HIV prevalence rate ratios (RRs) equaled 3.7 for blacks in 2006 and 3.6 in 2007 and 1.7 for Hispanics in both years (all P < 0.001). Among all MSM with HIV, the mortality rates were 199.8 (2006) and 188.4 (2007), with RRs of 5.4 for blacks in 2006 and 4.9 in 2007, and 1.6 for Hispanics in 2006 and 1.4 in 2007 (all P < 0.001). In 2006, the estimated HIV incidence rate among all MSM was 656.1 per 100,000 MSM, with RRs of 5.5 (blacks) and 2.0 (Hispanics) (both P < 0.001). A sensitivity analysis indicated that error due to misclassification of minority MSM as males who are not MSM lowered rates and RRs for all the 3 indicators but racial/ethnic disparities persisted (all P < 0.001).
The impact of HIV by each measure was greater on black and Hispanic MSM than on white MSM. Quantifying estimates of HIV incidence, HIV prevalence, and mortality rates among MSM with HIV informs HIV surveillance, prevention, treatment, resource allocation, and community mobilization.

    ABSTRACT: Black men who have sex with men (MSM) in the United States (US) are affected by HIV at disproportionate rates compared to MSM of other race/ethnicities. Current HIV incidence estimates in this group are needed to appropriately target prevention efforts. From July 2009 to October 2010, Black MSM reporting unprotected anal intercourse with a man in the past six months were enrolled and followed for one year in six US cities for a feasibility study of a multi-component intervention to reduce HIV infection. HIV incidence based on HIV seroconversion was calculated as number of events/100 person-years. Multivariate proportional hazards modeling with time-dependent covariates was used to identify correlates of HIV acquisition. Of 1,553 Black MSM enrolled, 1,164 were HIV-uninfected at baseline and included in follow-up. Overall annual HIV incidence was 3.0% (95% confidence interval (CI): 2.0, 4.4%) and 5.9% among men ≤30 years old (95% CI: 3.6, 9.1%). Men ≤30 years old reported significantly higher levels of sexual risk and were more likely to have a sexually transmitted infection diagnosed during follow-up. Younger men also were more likely to not have a usual place for health care, not have visited a health care provider recently, and to have unmet health care needs. In multivariate analysis, age ≤30 years (hazard ratio (HR): 3.4; 95% CI: 1.4, 8.3) and unprotected receptive anal intercourse with HIV-positive or unknown status partners (HR: 4.1; 95% CI: 1.9, 9.1) were significantly associated with HIV acquisition. In the largest cohort of prospectively-followed Black MSM in the US, HIV incidence was high, particularly among young men. Targeted, tailored and culturally appropriate HIV prevention strategies incorporating behavioral, social and biomedical based interventions are urgently needed to lower these rates.

    ABSTRACT: More than three decades after the first cases of HIV were recognized in the United States and worldwide, Africa remains a remarkable example of both public health successes and remaining challenges. Although many African countries initially lacked the resources and sociopolitical will to advance HIV treatment and prevention strategies, world governments, a committed scientific community, and activists have made tremendous advances. We present a public health perspective on the history of the HIV epidemic in Africa, combining summaries of the epidemiology of HIV infection rates and risk factors for horizontal and vertical HIV transmission, along with a historic perspective on programmatic and funding initiatives that have strongly reduced levels of HIV infection across the continent. In our preparation of this review two clear themes emerged: that (1) the HIV epidemic in Africa remains geographically and culturally heterogeneous, so that treatment and prevention strategies need to be thoughtfully tailored for maximal effectiveness; and (2) a lack of openness to recognize and discuss infection disparities in high risk groups, disseminate prevention information, and enact policies to partner with these highly stigmatized risk groups. This is especially true of female sex workers, people who inject drugs, and men who have sex with men, communities that are often not recognized or typically undercounted when HIV testing and prevention policies are developed by many African governments. Without changes to recognize and de-stigmatize these high-risk groups, a lack of sociopolitical will to alter public health perspectives will likely hinder advances to further curb the HIV epidemic.
