An emerging HIV risk environment: a preliminary epidemiological profile of an MSM POZ Party in New York City.

OBJECTIVE: To develop a preliminary epidemiological description of a men who have sex with men (MSM) "POZ Party," an emerging sex environment for HIV+ MSM. METHODS: As part of a pilot study in New York City in 2003, data were collected using a brief, behavioural intercept survey at entry to POZ Party events. Domains include demographic characteristics, history of HIV infection, motivations for attending POZ parties, lifetime and recent exposure to drugs (including use during POZ Party events), and recent sexual practices (both within both POZ Party venues as well as in non-POZ Party venues). RESULTS: Predominantly white and over the age of 30, subjects in the sample include a broad range of years living with HIV infection. Motivations for using a POZ Party venue for sexual partnering include relief from burdens for serostatus disclosure, an interest in not infecting others, and opportunities for unprotected sexual exchange. High rates of unprotected sex with multiple partners are prevalent in the venue. Although the sample evidences high rates of lifetime exposure to illicit drugs, relatively little drug use was reported in these sexual environments. These reports are consistent with evidence from direct observation at the venues themselves, in which no drug use was apparent. CONCLUSION: Serosorting among HIV+ MSM may reduce new HIV infections, a stated interest of both POZ Party organisers and participants alike. However, high rates of unprotected anal intercourse within these venues signal continued risk for STIs. Additionally, unprotected sexual contact with HIV partners and status unknown partners outside POZ Party venues heightens concern for diffusion of HIV superinfection.

A demographic and behavioral profile of homeless youth in New York City: implications for AIDS outreach and prevention.

Rapid changes in the world market economy have served to destabilize many local institutions, widening the gap between the rich and the poor and undermining viability of key social and economic institutions such as family and household. Among those most deeply affected by this displacement are children and adolescents, many of whom are forced to leave family institutions before they have acquired the skills and maturity needed to become economically self-sufficient. Fending for themselves amid the vagaries of the underworld of virtually every major city in the world, these youths are at exceptional risk for a wide range of poor health outcomes and premature death. While perhaps a familiar sight in many non-Western countries, this phenomenon also has emerged in the industrialized world, a fact that accounts for the rise in exposure to violence and disease among street-involved youth and young adults in nations such as the United States. There are as yet few empirical data available about the nature of these youth populations or the constellation of behaviors that place them at increased risk for disease outcomes. In this report we construct a demographic and behavioral profile of the homeless youth population in New York City, particularly as behavioral patterns relate to risk associated with HIV infection.

HIV-1 transmission in injection paraphernalia: heating drug solutions may inactivate HIV-1.

In response to recent concerns about risk of HIV-1 transmission from drug injection paraphernalia such as cookers, ethnographic methods were used to develop a descriptive typology of the paraphernalia and practices used to prepare and inject illegal drugs. Observational data were then applied in laboratory studies in which a quantitative HIV-1 microculture assay was used to measure the recovery of infectious HIV-1 in cookers. HIV-1 survival inside cookers was a function of the temperature achieved during preparation of drug solutions; HIV-1 was inactivated once temperature exceeded, on average, 65 degrees C. Although different types of cookers, volumes, and heat sources affected survival times, heating cookers 15 seconds or longer reduced viable HIV-1 below detectable levels.

HIV risk behaviors associated with the injection process: multiperson use of drug injection equipment and paraphernalia in injection drug user networks.

This study examines drug acquisition and multiperson use of paraphernalia, drugs, and needles/syringes. Ethnographers observed 54 injection episodes in which IDUs were linked by HIV risk behaviors, and developed a typology of higher-risk, lower-risk, and nonsharing-risk networks. Multiperson use of injection paraphernalia or drug solution occurred in most injection events (94%). Serial use of syringes/needles occurred infrequently (14%) relative to "backloading" (37%) and reuse of paraphernalia (cookers 84%, cotton 77%, water 77%). Higher-risk injection networks were characterized by larger size and pooling of resources for drugs. Prevention messages must include avoiding reuse of injection paraphernalia and transfer of drug solution.

Correlates and distribution of HIV risk behaviors among homeless youths in New York City: implications for prevention and policy.

Homeless youths are at high risk for poor health outcomes, including repeated exposure to STDs and high rates of unplanned pregnancies, untreated TB, HIV infection, and accelerated immune dysfunction associated with AIDS. This article examines the nature and distribution of HIV-risk behavior in a broad, street-based sample of homeless and runaway youths in New York City (N = 929). Although street youths in general are shown at high risk, the highest risks nest within older age segments of the male street youth population. Paradoxically, these youths are least likely to be in contact with prevention services. The data demonstrate the need to reconsider the use of chronological age as a determinant for service eligibility and to reconfigure funding streams so as to more effectively and consistently target older and more vulnerable youths.

Dominican, Mexican, and Puerto Rican prostitutes: drug use and sexual behaviors.

PIP: HIV-related behaviors are reported in three groups of Hispanic prostitutes recruited in the US: 77 Dominicans recruited in the Washington Heights/Inwood section of New York City; 151 Mexicans recruited in El Paso, Texas; and 48 Puerto Ricans recruited in East Harlem, New York City, during 1989-91 in streets and brothels. Ethnographic interviews were conducted with a subsample of subjects (10 Puerto Ricans, 20 Mexicans, and 20 Dominicans) to examine the cultural meaning of risk behaviors. Structured interviews based on the NIDA AIDS Initial Assessment were conducted with the subjects to describe demographic characteristics and summarize levels of risk behaviors. Qualitative data showed that for the Mexican women in El Paso poverty, violence, drug dealing and transport, tourist clients, and an environment of illegality were the realities more than for the Dominican and Puerto Rican prostitutes. The Dominican sample in New York City transported to their new environment strong family values and proscriptions against drug use as well as prostitution in brothels on account of poverty-related motivations for the support of their children. The Puerto Rican women reflected acculturation evolved in two locations, as well as illicit drugs, violence, and abuse. 92% of the Dominican women, 71% of the Mexican women, and only 25% of the Puerto Rican women were born in their native countries. Only 10% of the Puerto Ricans, 36% of the Mexicans, and 53% of the Dominicans always used condoms. 58% of the Puerto Ricans, 21% of the Mexicans, and 13% of the Dominicans reported ever having a sexually transmitted disease (p 0.001). Of those tested by the project, only 2% of the Mexicans vs. 8% of the Dominicans were HIV positive. Among drug-addicted Puerto Ricans, the HIV seroprevalence rate was 40-50%. 79% of the Puerto Rican prostitutes were sex partners of iv drug users. For effective prevention, cultural diversity must be taken into account.^ieng

HIV risk behavior, street outreach, and condom use in eight high-risk populations.

In this paper we examine risk behavior, exposure to street outreach, and condom use in samples of injecting drug users (IDUs) and high-risk youth. We used systematic sampling methods to produce representative samples of injecting drug users IDUs (five sites) and high-risk youth (three sites). The populations surveyed engaged in high levels of sexual risk behavior: 20% to 46% reported two or more sex partners in the last month. The majority (62% to 97%) knew someone infected with HIV. Condom use rates approached national health promotion goals for nonsteady partners but not for steady or main partners. Having a condom at time of interview was the most consistent predictor of condom use at last intercourse. Many of the respondents have been in contact with street outreach programs and many acknowledged some personal risk for HIV infection. However, most of the injecting drug users and high-risk youth interviewed (and their sex partners) were still at risk through unprotected sex.

PIP: Samples of IV drug users (IVDUs) and high-risk youth were surveyed to gain insight into their HIV risk behavior, exposure to street outreach, and condom use. The IVDUs were sampled from Atlanta, Philadelphia, Chicago, New York, and Los Angeles; 69-77% are male; they are predominantly Hispanic and Black; and more than 50% were older than age 40 years. The high-risk youth were sampled from Los Angeles, San Diego, New York, and San Francisco. They were aged 12-23 years and had been recurrently without shelter during the past year, or had been without permanent shelter for the past two months, or had derived their livelihood from dealing drugs on the street, prostitution, panhandling, and crime. 65-81% are male, approximately 50% in New York are White and 78% in San Francisco, 39-54% were age 20 or older, and 52-73% were currently living on the street, although only 10-32% had stayed in a shelter during the past year. At least 75% were supported at least in part by the street economy and 15-33% identified themselves as gay or bisexual. Many of the youth covered in the survey in San Francisco were on tour with the Grateful Dead folk rock music group. 20-46% reported having two or more sex partners in the last month, up to one-third reported having no sex partner in the past month, 62-97% knew someone infected with HIV, and 18-26% of the IVDUs and 11-41% of youth reported sometimes exchanging sex for money, food, shelter, or other things. Among respondents who had sex during the past month, 17-44% reported using a condom during vaginal sex with main partners, and 55-75% with other partners. The highest rates of condom use were for anal sex, followed by vaginal and oral sex. In most categories, however, the majority of respondents were not using condoms to protect themselves from HIV or other sexually transmitted diseases. Having a condom at the time of interview was the most consistent predictor of condom use at last intercourse. Many of the respondents had been in contact with street outreach programs and many acknowledged some personal risk for HIV infection.

Outcomes of a risk-reduction intervention with high-risk populations: the Harlem AIDS project.

Many studies of interventions with high-risk populations have reported reductions in risk behaviors. To assess effectiveness of interventions, data are also needed on the characteristics of subjects lost to follow-up, and on follow-up risk behaviors for subjects who were not participants in the intervention. This paper reports on a study conducted in Harlem, New York, recruiting 1,770 injection drug users (IDUs) and sex partners of IDUs, randomly assigned to two interventions. Repeated-measures analyses for the two intervention groups and those who participated in no intervention indicated that all groups reported significant reductions in risk behaviors, with no group effect. Comparisons of those followed-up and not followed-up indicate that those followed-up were less likely to: be homeless, be Latinos, and to use "shooting galleries." The discussion focuses on the need to assess outcomes for all types of participants, and to distinguish the impact of interventions from other explanations for behavior changes.
