Effects of familial and non-familial warmth during childhood and adolescence on sexual-orientation disparities in alcohol use trajectories and disorder during emerging adulthood.

Background: We investigated sexual-orientation differences in typologies of self-reported familial and non-familial warmth in childhood (before age 11) and adolescence (ages 11-17); and tested whether warmth explained sexual minority emerging adults' (ages 18-25) heightened odds of having heavier alcohol use trajectories (AUTs) and heightened risk for past-year alcohol use disorder (AUD) compared to completely heterosexuals.

Methods: Using self-reported data from the U.S.

Sexual-orientation differences in alcohol use trajectories and disorders in emerging adulthood: results from a longitudinal cohort study in the United States.

Aims: We estimated sexual-orientation differences in alcohol use trajectories during emerging adulthood, and tested whether alcohol use trajectories mediated sexual-orientation differences in alcohol use disorders (AUDs).

Design: Longitudinal self-reported survey data from the Growing Up Today Study.

Setting: United States.

High HIV incidence among young black men who have sex with men: constructing a retrospective cohort from a community health programme.

Objectives: We sought to calculate HIV incidence in a retrospective cohort of young (13-29 years old) black men who have sex with men (YBMSM) accessing repeated HIV-antibody testing in a mid-size city in the USA.

Methods: We aggregated site-specific HIV-antibody testing results from the project's inception among YBMSM who received an initial negative result and accessed at least one additional HIV-antibody test. From these data, we assessed number of seroconversions and person-years and calculated HIV incidence using a mid-P exact test to estimate 95% CIs.

Stability of Bisexual Behavior and Extent of Viral Bridging Behavior Among Men Who Have Sex with Men and Women.

Bisexual men experience significant health disparities likely related to biphobia. Biphobia presents via several preconceptions, including that bisexuality is transitory, and that bisexual men act as viral bridges between men who have sex with men and heterosexual populations. We analyzed data from a prospective cohort of gay and bisexual men, the Multicenter AIDS Cohort Study, to test these preconceptions.

Someone to count on: social support as an effect modifier of viral load suppression in a prospective cohort study.

Though functional social support has been shown to serve as a protective factor for HIV viral load suppression in other populations, scant research has examined this relationship among men who have sex with men (MSM) in the United States. We assessed characteristics of social support, effects of social support on HIV viral load, and moderation by social support of the relationship between psychosocial indicators of a synergistic epidemic (syndemic) and HIV viral load. We analyzed longitudinal data from HIV-positive MSM using antiretroviral therapy who were enrolled in the Multicenter AIDS Cohort Study between 2002 and 2009 (n = 712).

Effects of syndemics on HIV viral load and medication adherence in the multicentre AIDS cohort study.

Objectives: The objective of this study is to determine associations between intertwining epidemics (syndemics) and HIV medication adherence and viral load levels among HIV-positive MSM and to test whether adherence mediates the relationship between syndemics and viral load.

Design: We analysed participant data collected between 2003 and 2009 from the Multicenter AIDS Cohort Study, a prospective HIV/AIDS cohort study in four U.S.

Stuck in the middle: longitudinal HIV-related health disparities among men who have sex with men and women.

Introduction: Men who have sex with men and women (MSMW) have been shown in cross-sectional studies to suffer HIV-related health disparities above and beyond those found among men who have sex with men only (MSMO). We conducted a secondary data analysis over a 7-year time frame of participants in the Multicenter AIDS Cohort Study, a long-standing prospective cohort study, to examine whether MSMW had persistently higher rates of depression symptoms, polydrug use, and (among HIV-positive men who have sex with men) HIV viral load levels compared with MSMO.

Methods: Men were behaviorally defined as bisexual if they reported sexual activity with at least 1 male and 1 female partner between study waves 38 and 50.

HIV infection and sexual risk among men who have sex with men and women (MSMW): a systematic review and meta-analysis.

Objectives: To estimate the number of men who have sex with men and women who are HIV-positive in the United States, and to compare HIV prevalence rates between men who have sex with men and women, men who have sex with men only, and men who have sex with women exclusively.

Methods: Following PRISMA guidelines, we conducted a systematic review and meta-analysis of reports referencing HIV prevalence and men who have sex with men and women. We searched PubMed and Ovid PsycINFO for peer-reviewed, U.

Labor force participation and health-related quality of life in HIV-positive men who have sex with men: the Multicenter AIDS Cohort Study.

Too many people with HIV have left the job market permanently and those with reduced work capacity have been unable to keep their jobs. There is a need to examine the health effects of labor force participation in people with HIV. This study presents longitudinal data from 1,415 HIV-positive men who have sex with men taking part in the Multicenter AIDS Cohort Study.

Sexual, behavioral, and quality of life characteristics of healthy weight, overweight, and obese gay and bisexual men: findings from a prospective cohort study.

While there have been attempts to explore the association of obesity and risky sexual behaviors among gay men, findings have been conflicting. Using a prospective cohort of gay and bisexual men residing in Pittsburgh, we performed a semi-parametric, group-based analysis to identify distinct groups of trajectories in body mass index slopes over time from 1999 to 2007 and then correlated these trajectories with a number of psychosocial and behavioral factors, including sexual behaviors. We found many men were either overweight (41.

Middle-aged and older men who have sex with men exhibit multiple trajectories with respect to the number of sexual partners.

This study aimed to examine trajectories with respect to the number of sexual partners among older men who have sex with men and to determine characteristics associated with trajectory groups. Nagin's group-based modeling was used to identify trajectories for 237 men from the Pitt Men's Study with respect to the number of male intercourse partners from age 50.0 to 59.

Intimate partner violence among HIV-positive persons in an urban clinic.

While the intersection of HIV/AIDS and intimate partner violence (IPV) has gained increased attention, little focus has been given to the relationship among minority men and men who have sex with men (MSM). This pilot study, conducted at an urban clinic, explores the IPV experiences of HIV-positive persons involved in both heterosexual and homosexual relationships. Fifty-six HIV-positive individuals were interviewed to assess for verbal, physical, and sexual IPV, and for HIV-related abuse and attitudes regarding routine IPV screening.

A Twenty-Two-Year-Old Community Advisory Board: Health Research as an Opportunity for Social Change.

Conducting health research often requires a partnership between marginalized communities and researchers. Community organizers can broker this partnership in a way that not only produces important scientific discoveries but also brings needed resources to the communities. This article is a description of a community advisory board established in 1984 to advise researchers on a longitudinal study of the natural history of AIDS among gay men.

Impact of early sexual debut on gay men's tobacco use.

Young men's sexual experiences with men are different from their sexual experiences with women because of homophobia. Early sexual debut with another man could lead to tobacco use as a result. The study assessed 691 HIV-negative gay men recruited from southwestern Pennsylvania.

Recruiting minority men who have sex with men for HIV research: results from a 4-city campaign.

We describe the efforts of a 4-city campaign to recruit Black and Hispanic men who have sex with men into an established HIV epidemiological study. The campaign used community organizing principles and a social marketing model that focused on personnel, location, product, costs and benefits, and promotion. The campaign was developed at the community, group, and individual levels to both increase trust and reduce barriers.

Adolescents define sexual orientation and suggest ways to measure it.

Researchers disagree on how to assess adolescent sexual orientation. The relative importance of various dimensions (e.g.

Mental health case management as a locus for HIV prevention: results from case-manager focus groups.

HIV infection among people with severe mental illness (SMI) is a growing concern, and interventions have been designed to address HIV prevention among these individuals. However, little is known about the preparedness of mental health providers to support these interventions. This study concentrated on mental health case management as a locus for HIV-prevention services.
