Optimal Allocation of Societal HIV Prevention Resources to Reduce HIV Incidence in the United States
Objectives. To optimize combined public and private spending on HIV prevention to achieve maximum reductions in incidence. Methods. We used a national HIV model to estimate new infections from 2018 to 2027 in the United States. We estimated current spending on HIV screening, interventions that move persons with diagnosed HIV along the HIV care continuum, pre-exposure prophylaxis, and syringe services programs. We compared the current funding allo…
Patterns of Racial/Ethnic Disparities and Prevalence in HIV and Syphilis Diagnoses Among Men Who Have Sex With Men, 2016
Objectives. To describe disparities in HIV infection and syphilis among gay, bisexual, and other men who have sex with men (MSM) in US states through ratio-based measures and graphical depictions of disparities. Methods. We used state-level surveillance data of reported HIV and syphilis cases in 2015 and 2016, and estimates of MSM population sizes to estimate HIV and syphilis prevalence by race/ethnicity and rate ratios (RRs) and to visually disp…

Young People and HIV
HIV is having a significant impact on young people, among whom the rate of new diagnoses is high and health disparities are more pronounced. Incidence is increasing among young gay and bisexual men, and, among Black males, the largest percentage of new infections occur among those aged between 13 and 24 years. Youths are least likely to experience the health and prevention benefits of treatment. Nearly half of young people with HIV are not diagno…
Syndemic Vulnerability, Sexual and Injection Risk Behaviors, and HIV Continuum of Care Outcomes in HIV-Positive Injection Drug Users
Incorporating Couples-Based Approaches into HIV Prevention for Gay and Bisexual Men
Opportunities for HIV combination prevention to reduce racial and ethnic health disparities
Despite advances in HIV prevention and care, African Americans and Latino Americans remain at much higher risk of acquiring HIV, are more likely to be unaware of their HIV-positive status, are less likely to be linked to and retained in care, and are less likely to have suppressed viral load than are Whites. The first National HIV/AIDS Strategy (NHAS) has reducing these disparities as one of its three goals by encouraging the implementation of co…
A Review of the Literature on Event-Level Substance Use and Sexual Risk Behavior Among Men Who Have Sex with Men
Estimating the Population Size of Men Who Have Sex with Men in the United States to Obtain HIV and Syphilis Rates§
BACKGROUND: CDC has not previously calculated disease rates for men who have sex with men (MSM) because there is no single comprehensive source of data on population size. To inform prevention planning, CDC developed a national population size estimate for MSM to calculate disease metrics for HIV and syphilis. METHODS: We conducted a systematic literature search and identified seven surveys that provided data on same-sex behavior in nationally re…
Is Injection Serosorting Occurring among HIV-Positive Injection Drug Users? Comparison by Injection Partner’s HIV Status
Efficacy of a Health Educator–Delivered HIV Prevention Intervention for Latina Women
Objectives. We developed and assessed AMIGAS (Amigas, Mujeres Latinas, Inform andonos, Gui andonos, y Apoy andonos contra el SIDA [friends, Latina women, informing each other, guiding each other, and supporting each other against AIDS]), a culturally congruent HIV prevention intervention for Latina women adapted from SiSTA (Sistas Informing Sistas about Topics on AIDS), an intervention for African American women. Methods. We recruited 252 Latina …
Beliefs about transmission risk and vulnerability, treatment adherence, and sexual risk behavior among a sample of HIV-positive men who have sex with men
Advances in HIV treatment have generated optimistic beliefs about HIV transmission risk and sexually transmitted infection vulnerability, which can influence motivation to practice safer sex. This study sought to better understand the relationships between these beliefs and different types of sexual risk behavior. A second objective was to determine the association between treatment adherence and sexual risk behaviors. Data collected from 842 HIV…
Managing identity impacts associated with disclosure of HIV status
Disclosure of HIV status to potential and current sex partners by HIV-positive people (HIVPP) is a complex issue that has received a significant amount of attention. Research has found that disclosure depends upon the evaluation by HIVPP of potential benefits and risks, especially of the risks stemming from the profound social stigma of HIV and AIDS. Drawing on concepts from Goffman's classic stigma theory and Anderson's more recently developed c…

Sexual Risk Behaviors Among HIV-Positive Black Men Who Have Sex With Women, With Men, or With Men and Women
Objectives. We compared demographics and sexual and drug risk behaviors among HIV-positive Black men who have sex with women only, with men only, or with men and women to assess differences among and between these groups. Methods. We analyzed cross-sectional data from the Supplement to HIV and AIDS Surveillance Project for 2038 HIV-positive Black men who reported being sexually active. We classified the participants by their reported sexual behav…
Recommendations From a Research Consultation to Address Intervention Strategies for HIV/Aids Prevention Focused on African Americans
Despite substantial federal resources spent on HIV prevention, research, treatment, and care, as well as the availability and dissemination of evidence-based behavioral interventions, the disparate impact of HIV on African Americans continues. In October 2007, 3 federal agencies convened 20 HIV/AIDS prevention researchers and care providers for a research consultation to focus on new intervention strategies and current effective intervention stra…

Characteristics of bisexually active men in the Seropositive Urban Mens’ Study (Sums)
Characteristics of bisexually-active men were compared with those of their homosexually-active counterparts in a study of HIV-seropositive men who have sex with men (MSM). Men who had had sex with women in the prior year were younger and more likely to be African American than those reporting sex only with men. They reported higher levels of internalised homophobia and less participation in the gay community. They tended to be recruited through f…

OBJECTIVE: To conduct a meta-analytic review of HIV interventions for people living with HIV (PLWH) to determine their overall efficacy in reducing HIV risk behaviours and identify intervention characteristics associated with efficacy. METHODS: Comprehensive searches included electronic databases from 1988 to 2004, hand searches of journals, reference lists of articles, and contacts with researchers. Twelve trials met the stringent selection crit…
Sexual behavior among hiv‐positive men who have sex with men
Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self-labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV-seropositive men who have sex with men. The majority of participants (88%) identified as a top, a bottom, or versatile. Tops were more likely t…

Experiencing release
There are nonsexual reasons that may motivate people to seek out sexual activity with others. Some men who have sex with men may seek out sex environments to engage in sexual behavior. Among the nonsexual reasons that exist for men who have sex with men is a desire to escape from distressing thoughts and feelings. The amplified sexuality and other unique characteristics of sex environments allow men to have more intense emotional experiences arou…

The Car and the City
Transportation systems that rely predominantly on privately owned automobiles are clearly unsustainable, yet the number of such vehicles continues to grow every year. This article explores the causes of this anomaly. The ineffectiveness of “end-of-pipe” solutions to automobile dominance is demonstrated, and more effective strategies are explored. A computer simulation of highway traffic clarifies the fragility of traffic management systems and th…

Childhood sexual abuse and sexual transmission risk behaviour among HIV-positive men who have sex with men
Previous studies have indicated an association between childhood sexual abuse (CSA) and adult sexual risk behaviour among women and among men who have sex with men (MSM). However, no studies to date have tested the hypothesis that a history of CSA predicts sexual behaviour carrying risk of transmission of HIV to others, i.e. in a known HIV-positive cohort. The present study tested this hypothesis among a sample of 456 HIV-positive MSM recruited f…
