Association Between Socioeconomic Status Mobility and Inflammation Markers Among White and Black Adults in the United States: A Latent Class Analysis.

Objective: This article examines whether multidimensional indicators of objective and subjective socioeconomic status (SES) across the life course can be categorized into latent classes of SES mobility and tests the associations of these categories with inflammation markers among white and black adults.

Methods: Data are from 592 non-Hispanic white and 158 non-Hispanic black participants who completed both the baseline survey and biomarkers assessment of the Midlife in the United States Refresher study. Groups of different SES mobility were examined using latent class analysis.

Sexual Minority-related Discrimination across the Life Course: Findings from a National Sample of Adults in the United States.

In the United States, sexual minority (SM) status is associated with a number of health disparities. Based on mounting evidence, stigma and discrimination have been cited as key barriers to health equity for this population. We estimated the prevalence of three types of discrimination as a function of age among SM adults from the National Epidemiological Study of Alcohol Use and Related Conditions III (NESARC-III) (2012-2013).

Sexual minority health disparities: an examination of age-related trends across adulthood in a national cross-sectional sample.

Purpose: Sexual minorities experience significant health disparities across a variety of mental, behavioral, and physical health indicators. Yet, an understanding of the etiology and progression of sexual minority health disparities across the lifespan is limited.

Methods: We used the U.

A Focus on the HIV Care Continuum Through the Healthy Young Men's Cohort Study: Protocol for a Mixed-Methods Study.

Background: No group is at greater risk for acquiring HIV than young men who have sex with men (YMSM), particularly black or African American (AA) and Hispanic or Latino (L) YMSM living in inner cities, who account for the largest number of new HIV infections each year. Although pre-exposure prophylaxis (PrEP), postexposure prophylaxis (PEP), and treatment as prevention hold enormous promise for changing the course of the epidemic, AA/L-YMSM are the least likely population to be receiving primary health care and HIV prevention/care and are the least likely to be using PrEP and PEP.

Objective: The overarching aim of the Healthy Young Men's (HYM) cohort study is to conduct longitudinal research with a cohort of AA/L-YMSM to prevent new HIV infections, reduce transmission, and reduce HIV/AIDS-related disparities by focusing on successful engagement in care.

Patterns of Sexual Behaviors in Young Men Who Have Sex With Men in Mexico.

Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior. However, little is known about patterns of sexual behavior among men who have sex with men (MSM) in Mexico, men who are at greatest risk for HIV and sexually transmitted infections compared to other subpopulations in the country. This study applied latent class analysis to data from a large, HIV-negative sample of 18- to 25-year-old Mexican MSM recruited from a social and sexual networking website (N = 3,722) to uncover multidimensional patterns of sexual behaviors, partner factors, and protective behaviors, and examine how these were associated with health and well-being correlates.

Disparities in substance use behaviors and disorders among adult sexual minorities by age, gender, and sexual identity.

Background: Sexual minorities (SMs) experience elevated rates of substance use behaviors and disorders relative to heterosexuals; minority stress is theorized to contribute to these disparities. As SMs are not a homogenous group, analyses that aggregate SMs across sexual identity, age, or gender obscure important variation among this population. To date, age- and gender-specific disparities have not been rigorously examined using a large national sample.

Patterns of Sexual Behavior and Sexually Transmitted Infections in Young Men Who Have Sex With Men.

Purpose: Young men who have sex with men (MSM) are at an increased risk for sexually transmitted infections (STIs). Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior; however, little is known about how multidimensional patterns of sexual behavior among MSM may be associated with STIs.

Method: This study applies latent class analysis to data from a large, HIV- sample of 18- to 25-year-old MSM recruited from social and sexual networking Web sites (N = 5965; 76% white, 11% Latino, 5% black, 4% Asian, 4% other; 74% homosexual, 21% bisexual, 1% heterosexual, 3%, unsure/questioning 1% other) to uncover multidimensional patterns of past-year sexual behaviors, partner factors, and protective behavior and their associations with self-reported STI diagnosis.

Time Since First Acting on Same-Sex Attraction and Recreational Drug Use among Men Who Have Sex With Men (MSM): Is There an Effect of "Gay Age"?

Background: Men who have sex with men (MSM) have higher rates of substance use compared to men who have sex with women. Among MSM, drug use is linked to higher-risk sexual behavior and acquisition of HIV and other sexually transmitted infections.

Objectives: We hypothesize that time since first acting on one's same sex attraction, or one's "gay age", could be predictive of drug using behavior.

Sexual Behavior Latent Classes Among Men Who Have Sex With Men: Associations With Sexually Transmitted Infections.

Men who have sex with men (MSM) are at disproportionate risk of acquisition of sexually transmitted infections (STIs). We used latent class analysis (LCA) to examine patterns of sexual behavior among MSM and how those patterns are related to STIs. We examined patterns of sexual behavior using behavioral and clinical data from a cross-sectional study of 235 MSM who presented to an urban sexual health clinic for STI testing.

Timing of First Sexual Intercourse and Young Adult Health Outcomes.

Purpose: To examine how age of onset of sexual intercourse is associated with past-year and lifetime sexually transmitted infections (STIs) and depression in young adulthood.

Methods: We examined how occurrence of a lifetime and past-year STI, lifetime diagnosis of depression, and past-week depressive symptoms differed as a function of age of onset of sexual intercourse using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 8,938 individuals). Time-varying effect models were used to examine how age of onset, measured as continuous age, was associated with these outcomes in young adulthood, with all analyses stratified to examine gender differences.

Group Sex and Prevalent Sexually Transmitted Infections Among Men Who Have Sex with Men.

We evaluated the direct relation between group sex and prevalent sexually transmitted infections (STI) in a cross-sectional study of men who have sex with men (MSM) presenting at an urban STI clinic in the Midwestern US. Among 231 men who enrolled and reported that they have sex with men, we collected behavioral data using a combination of interviewer and self-administered surveys and extracted STI data from electronic health records. We used modified Poisson regression to examine the unadjusted and adjusted associations between group sex participation and prevalent STI.

Body image and sexually transmissible infection prevalence among men who have sex with men.

Compared with men who have sex with women, some evidence suggests that men who have sex with men (MSM) have increased prevalence of body image dissatisfaction. MSM also have a higher prevalence of sexually transmissible infections (STIs) than other population groups. As part of a cross-sectional study, body image among 104 MSM using the standardised, validated Male Body Attitudes Scale was assessed.

Elevated cytokine and chemokine levels in the placenta are associated with in-utero HIV-1 mother-to-child transmission.

Objective: To determine whether there is an association between cytokine and chemokine levels in plasma isolated from the placenta and HIV-1 mother-to-child transmission (MTCT).

Design: We designed a case-control study of HIV-infected, pregnant women enrolled in the Malaria and HIV in Pregnancy cohort. Participants were recruited in Blantyre, Malawi, from 2000 to 2004.
