BACKGROUND: HIV/AIDS continues to be a health disparity faced by sexual minority men, and is exacerbated by non-injection drug use. OBJECTIVES: We sought to delineate growth in non-injection drug use and condomless sex in a sample of racially and economically diverse of gay, bisexual, and other young men who have sex with men (YMSM) as they emerged into adulthood between the ages of 18 and 21 and who came of age in the post-HAART era. METHODS: Behavioral data on drug use and condomless sex, collected via a calendar based technique over 7 waves of a cohort study of 600 YMSM, were analyzed using latent growth curve modeling to document patterns of growth in these behaviors, their associations, and the extent to which patterns and associations are moderated by race/ethnicity and socioeconomic status...

Young men who have sex with men (YMSM) are disproportionately impacted by HIV/AIDS and have elevated rates of substance use. Parenting practices, such as knowledge of child whereabouts and monitoring of behavioral rules, protect against these outcomes among heterosexual youth. This article examined the relationship between these parenting practices and substance use and HIV risk behaviors among YMSM. Data are reported from three similar studies of YMSM: ChiGuys (ages 14-18), Crew 450 (ages 16-22), and RADAR (ages 16-29)...

OBJECTIVE: Decision-making involves fronto-striatal brain areas that are particularly vulnerable to the effects of HIV infection. Some studies report impaired decision-making in people with HIV/AIDS with past or present addictions and/or accompanying HIV-associated neurocognitive disorders (HAND). The authors investigated risk-based decision-making in HIV/AIDS, separating individuals with or without accompanying HAND. METHOD: A total of 288 HIV-infected persons underwent standardized neuropsychological testing...

BACKGROUND: Recent evidence suggests that sexualized text communication ("sexting") is associated with substance use and sexual risk behaviors among young adults, yet little is known about this relationship among young adult African American gay and bisexual men, a population disproportionately impacted by HIV in the United States. Rapid advances in mobile phone technology indicate a clear need for research using mobile health (mHealth) methods such as ecological momentary assessment (EMA) to serve as a viable counterpart to retrospective evaluation methods by using real-time data collection to assess sexting and substance use among this population...

Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) disproportionately burdens African American youth and young adults. In studies conducted in Historically Black Colleges and Universities (HBCU) settings, African American youth generally perceive themselves as having a low risk of contracting HIV and sexually transmitted diseases (STDs) despite having higher rates of unprotected sexual encounters, multiple sex partners, and particularly low rates of HIV testing and awareness of HIV status...

Despite improved survival due to combination antiretroviral therapy (cART), youth with perinatally-acquired HIV (PHIV) show cognitive deficits and developmental delay at increased rates. HIV affects the brain during critical periods of development, and the brain may be a persistent reservoir for HIV due to suboptimal blood brain barrier penetration of cART. We conducted structural magnetic resonance imaging (sMRI) and cognitive testing in 40 PHIV youth (mean age=16.7years) recruited from the NIH Pediatric HIV/AIDS Cohort Study (PHACS) who are part of the first generation of PHIV youth surviving into adulthood...

BACKGROUND: Marijuana use is common among HIV+ individuals, but few studies have examined long-term trends in prevalence and correlates of use. METHODS: We evaluated trends (1984-2013) in the annual prevalence of current (past 6-month use) and daily (among current users) marijuana use and determined correlates of use among 2742 HIV-seropositive (HIV+) and 3172 HIV-seronegative (HIV-) men who have sex with men in the Multicenter AIDS Cohort Study (MACS). Poisson regression models were used to estimate prevalence ratios of marijuana use separately for the men who were enrolled before 2001 (early-cohort) and after 2001 (late-cohort)...

To construct longitudinal trajectories of marijuana use in a sample of men who have sex with men living with or at-risk for HIV infection. We determined factors associated with distinct trajectories of use as well as those that serve to modify the course of the trajectory. Data were from 3658 [1439 HIV-seropositive (HIV+) and 2219 HIV-seronegative (HIV-)] participants of the Multicenter AIDS Cohort Study. Frequency of marijuana use was obtained semiannually over a 29-year period (1984-2013). Group-based trajectory models were used to identify the trajectories and to determine predictors and modifiers of the trajectories over time...

BACKGROUND: The most robust neurocognitive effect of marijuana use is memory impairment. Memory deficits are also high among persons living with HIV/AIDS, and marijuana is the most commonly used drug in this population. Yet research examining neurocognitive outcomes resulting from co-occurring marijuana and HIV is limited. OBJECTIVE: The primary objectives of this comprehensive review are to: (1) examine the literature on memory functioning in HIV-infected individuals; (2) examine the literature on memory functioning in marijuana users; (3) synthesize findings and propose a theoretical framework to guide future research...

The major psychoactive compounds in marijuana (cannabis) are cannabinoids, the most significant of which is delta-9-tetrahydrocannabinol. There are also two synthetic pharmaceutical cannabinoids, nabilone and dronabinol, available by prescription in the United States. The use of marijuana has increased in the United States with passage of medical marijuana laws in many states and legalization of recreational marijuana use in several states. In addition, the potency of marijuana has increased in recent years...

We measured the trend of cigarette smoking among HIV-seropositive and seronegative men over time from 1984 to 2012. Additionally, we examined the demographic correlates of smoking and smoking consumption. Six thousand and five hundred and seventy seven men who have sex with men (MSM) from the Multicenter AIDS Cohort Study (MACS) were asked detailed information about their smoking history since their visit. Prevalence of smoking and quantity smoked was calculated yearly from 1984 to 2012. Poisson regression with robust error variance was used to estimate prevalence ratios of smoking in univariate and multivariate models...
