Trends in sexual risk-taking among urban young men who have sex with men, 1999-2002.

As part of an HIV prevention study, 15-25 year-old young men who have sex with men (YMSM) were surveyed in community settings annually from 1999 to 2002. Data are presented from six comparison communities in the study; these communities recruited Latinos (Jackson Heights, NYC; San Gabriel Valley, CA), African Americans (Atlanta, GA); Asians/Pacific Islanders (San Diego, CA); and primarily white men (Detroit, MI and Twin Cities, MN). Men were asked about unprotected anal intercourse (UAI) in the past three months with male partners. The prevalence of UAI reported in these six communities ranged 27-35% in 1999, compared with 14% to 39% in 2002. Significant reductions in UAI over time were observed in Jackson Heights and San Gabriel Valley. A quadratic trend was noted in Detroit, with a significant increase in UAI from 1999 to 2000 followed by a significant decrease in UAI from 2000 to 2002. There was a nonsignificant increase in UAI in the Twin Cities, and no significant trends in UAI in Atlanta or San Diego. Behavioral trends among YMSM vary considerably across subpopulations and highlight the necessity of local behavioral surveillance and culturally tailored prevention efforts for specific racial and ethnic groups.

Predictors of risky sexual behavior among young African American men who have sex with men.

This study examined the prevalence and correlates of unprotected anal intercourse among 758 young African American men who have sex with men. A quarter of the sample reported unprotected anal intercourse in the past 3 months; nonsupportive peer norms and not carrying condoms predicted risky sexual behavior. Effective interventions are needed that promote the use of condoms by changing peer norms and encouraging carrying condoms.

Being high and taking sexual risks: findings from a multisite survey of urban young men who have sex with men.

Adolescent and young adult males who have sex with men (MSM) remain at high risk of HIV infection. Many sexual risk factors have been identified, yet the role of substance use remains controversial. We assess the extent to which urban young MSM report being "high" on drugs or alcohol during sex and the association between being "high" and unprotected anal intercourse (UAI). During summer 2000, 3,075 MSM aged 15-25 years completed a 20-minute interview for the Community Intervention Trial for Youth Project. Participants were asked about their last sexual contact with main and nonmain partners, including whether they were "high on drugs or alcohol." 18.6% of MSM with a main partner reported being high during their last sexual encounter; 25.0% reported UAI. Among men with a nonmain partner, 29.3% reported being high, and 12.3% reported UAI. Being high was associated with unprotected receptive anal intercourse with nonmain partners (odds ratio = 1.66, p = .02). HIV prevention should include messages about the potential dangers of drinking and drug use in situations where sexual encounters with nonmain partners may occur.

A venue-based method for sampling hard-to-reach populations.

Constructing scientifically sound samples of hard-to-reach populations, also known as hidden populations, is a challenge for many research projects. Traditional sample survey methods, such as random sampling from telephone or mailing lists, can yield low numbers of eligible respondents while non-probability sampling introduces unknown biases. The authors describe a venue-based application of time-space sampling (TSS) that addresses the challenges of accessing hard-to-reach populations. The method entails identifying days and times when the target population gathers at specific venues, constructing a sampling frame of venue, day-time units (VDTs), randomly selecting and visiting VDTs (the primary sampling units), and systematically intercepting and collecting information from consenting members of the target population. This allows researchers to construct a sample with known properties, make statistical inference to the larger population of venue visitors, and theorize about the introduction of biases that may limit generalization of results to the target population. The authors describe their use of TSS in the ongoing Community Intervention Trial for Youth (CITY) project to generate a systematic sample of young men who have sex with men. The project is an ongoing community level HIV prevention intervention trial funded by the Centers for Disease Control and Prevention. The TSS method is reproducible and can be adapted to hard-to-reach populations in other situations, environments, and cultures.
