Although stigma is considered a major barrier to effective responses to the HIV/AIDS epidemic, stigma reduction efforts are relegated to the bottom of AIDS programme priorities. The complexity of HIV/AIDS-related stigma is often cited as a primary reason for the limited response to this pervasive phenomenon. In this paper, we systematically review the(More)
This paper makes five key points. First is that the aggregate effect of radical and sustained behavioural changes in a sufficient number of individuals potentially at risk is needed for successful reductions in HIV transmission. Second, combination prevention is essential since HIV prevention is neither simple nor simplistic. Reductions in HIV transmission(More)
AIMS To measure the prevalence and independent associations of heavy and problematic use of alcohol and recreational drugs among a household-based sample of urban MSM (men who have sex with men). DESIGN Cross-sectional survey. PARTICIPANTS Men who identified as being gay or bisexual or who reported sex with another man in the prior 5 years were included(More)
OBJECTIVES Risk factors for HIV acquisition were examined in a recent cohort of men who have sex with men (MSM). DESIGN A longitudinal analysis of 4295 HIV-negative MSM enrolled in a randomized behavioral intervention trial conducted in six US cities. METHODS MSM were enrolled and assessed for HIV infection and risk behaviors semi-annually, up to 48(More)
OBJECTIVES This study characterized the AIDS epidemic among urban men who have sex with men (MSM). METHODS A probability sample of MSM was obtained in 1997 (n = 2881; 18 years and older) from New York, Los Angeles, Chicago, and San Francisco, and HIV status was determined through self-report and biological measures. RESULTS HIV prevalence was 17% (95%(More)
BACKGROUND With increasing calls for linking HIV-infected individuals to treatment and care via expanded testing, we examined sociodemographic and behavioral characteristics associated with HIV testing among men and women in Soweto, South Africa. METHODS We conducted a cross-sectional household survey involving 1539 men and 1877 women as part of the(More)
An unprecedented number of human sexuality studies have been initiated in response to the acquired immune deficiency syndrome (AIDS) epidemic. Unfortunately, methodological developments in the field of sex research have been slow in meeting the demands of AIDS investigations focusing on the diverse populations at risk for infection with the human(More)
OBJECTIVES Since young gay men are engaging in alarmingly high rates of unsafe sex and few seek help for changing risky behaviors, community-level programs to prevent infection with the human immunodeficiency virus (HIV) among them are urgently needed. METHODS We developed and implemented a community-level HIV prevention program in a midsized Oregon(More)
BACKGROUND Previous studies have found high rates of childhood sexual abuse (CSA) among US men who have sex with men (MSM). CSA history has been associated with a variety of negative effects later in life including behaviors that place MSM at greater risk for HIV acquisition and transmission. The present analysis is the first to examine the longitudinal(More)
This report presents a three-stage model (ARRM) that characterize people's efforts to change sexual behaviors related to HIV transmission. ARRM focuses on social and psychological factors hypothesized to influence (1) labeling of high risk behaviors as problematic, (2) making a commitment to changing high risk behaviors, and (3) seeking and enacting(More)
