Substance Use in the MSM Population of New York City during the Era of HIV/AIDS

This literature review considers the historical significance, emergence of, and interplay between the HIV and illicit drug use epidemics among gay, bisexual, and other men who have sex with men (MSM) in New York City (NYC). The continual rise in HIV infections in recent years among MSM, particularly among young MSM (YMSM), commands a need for the examination of the effectiveness of current HIV prevention strategies and a more comprehensive understanding of the complex biopsychosocial influences that place YMSM at risk. A chronological perspective of both the HIV and illicit drug use epidemics affecting NYC MSM is presented, followed by a review of the existing research on the synergistic relation between the two. Special consideration is given to the patterns and interconnectivity between HIV, substance use, and housing instability specific to YMSM, as they represent the demographic currently at greatest risk for HIV transmission in NYC. Thereafter, an overview of treatment research is provided. We conclude by offering recommendations for future research and best practices as we move forward in an attempt to reduce the incidence of HIV transmission.     

Heroin Use and Injection Risk Behaviors in Colombia: Implications for HIV/AIDS Prevention

Background: Heroin production in Colombia has increased dramatically in recent decades, and some studies point to an increase in local heroin use since the mid-1990s. Despite this rapid increase, little is known about the effects of these activities on heroin injection within Colombia. One of the biggest concerns surrounding heroin injection is the potential spread of HIV through drug user networks. Objectives: This article examines injection risk behaviors among heroin injectors in the Colombian cities of Medellín and Pereira to explore the implications for possible increased HIV transmission within this group. Methods: A cross-sectional study used respondent-driving sampling to recruit a sample of 540 people who inject drugs (PWID) over 18 years of age (Medellín: n = 242, Pereira: n = 298). Structured interviews with each participant were conducted using the World Health Organization Drug Injection Study Phase II Survey. An HIV test was also administered. Results: Information regarding the socio-demographics, injection drug use, HIV risk and transmission behaviors, injection risk management, and HIV knowledge and prevalence of participants are reported. The study identified many young, newly initiated injectors who engage in risky injection practices. The study also found that HIV prevalence is fairly low among participants (2.7%). Conclusions/Importance: Findings indicate a potential risk for the spread of HIV among PWID in Colombia given their widespread sharing practices, high rate of new injector initiation, and unsafe syringe cleaning practices. Colombia has a possibly time-limited opportunity to prevent an HIV epidemic by implementing harm reduction interventions among young, newly initiated PWID.     

Lifetime Substance Use and HIV Sexual Risk Behaviors Predict Treatment Response to Contingency Management Among Homeless,Substance-Dependent MSM

Abstract

Homeless, substance-dependent men who have sex with men (MSM) continue to suffer health disparities, including high rates of HIV. One-hundred and thirty one homeless, substance- dependent MSM were randomized into a contingency management (CM) intervention to increase substance abstinence and health-promoting behaviors. Participants were recruited from a community-based, health education/risk reduction HIV prevention program and the research activities were also conducted at the community site. Secondary analyses were conducted to identify and characterize treatment responders (defined as participants in a contingency management intervention who scored at or above the median on three primary outcomes). Treatment responders were more likely to be Caucasian/White (p < .05), report fewer years of lifetime methamphetamine, cocaine, and polysubstance use (p ≤ .05), and report more recent sexual partners and high-risk sexual behaviors than nonresponders (p < .05). The application of evidence-based interventions continues to be a public health priority, especially in the effort to implement effective interventions for use in community settings. The identification of both treatment responders and nonresponders is important for intervention development tailored to specific populations, both in service programs and research studies, to optimize outcomes among highly impacted populations.     

Substance Use,Sexual Identity,and Health Care Provider Use in Men Who Have Sex With Men

This article describes the association between substance use, sexual identity, and seeing a health care provider on a regular basis for 257 men who have sex with men (MSM). Data from in-person interviews were gathered from MSM who resided in Massachusetts between 2003 and 2007. A logistic regression analysis that controlled for demographic characteristics, health insurance status, HIV/AIDS status, drug use, and social support revealed that MSM who identified as heterosexual, compared with those who identified as gay or bisexual, were 60% less likely to access a health care provider on a regular basis. Further, the likelihood of seeing a provider regularly was 54% lower for MSM who had used illegal drugs in the past 30 days and 32% higher for MSM who had more social support. Study limitations and implications are discussed.     

A Longitudinal Study of Truant Youths' Involvement in Sexual Risk Behavior

ABSTRACT

Truant youths are likely to engage in a number of problem behaviors, including sexual risky behaviors. As part of a National Institute on Drug Abuse (NIDA)-funded, prospective intervention project, a sample of truant youths' sexual risk behavior was tracked over five time points. Analyses of the data was informed by four objectives: (a) determine if a growth model parameterization was consistent with the youths' sexual risk behavior, (b) assess the impact of a brief intervention (BI) targeting substance use on their sexual risk behavior over time, (c) identify any sexual risk behavior subgroups, and (d) identify any differential, longitudinal effects of the BI on the youths' sexual risk behavior. Results indicated the youths' sexual risk behavior reflected a linear growth model; no intervention effects were found on their sexual risk behavior over time; distinct sexual risk behavior subgroups were found; and no patterned intervention effects were found in regard to the sexual risk behavior subgroups. At the same time, there is a very serious need to provide effective sexual risk reduction intervention services to truant youths.     

Using the Primary Socialization Theory to Predict Substance Use and Sexual Risk Behaviors Between Black and White Adolescents

Using the Primary Socialization Theory (PST), we examined substance use and sexual risk-taking behaviors between Black (N = 1,464) and White (N = 3,946) adolescents in the National Longitudinal Study of Adolescent Health, Wave 1, public use (Add Health). Self-reported substance use and sexual risk-taking behaviors, PST constructs, and covariates were assessed using regression modeling techniques. Black youth were more likely to initiate sex, while White youth were more likely to report lifetime alcohol use. The PST predicted risk for White but not Black youth. The study's limitations are noted, and implications for future research are discussed.
