BACKGROUND: Latino gay, bisexual, and other men who have sex with men (MSM) in the United States have a 50% greater incidence of HIV when compared to White MSM. Previous studies have analyzed factors contributing to condomless anal intercourse (CAI) among Latino MSM, but few studies have followed cohorts of HIV-negative Latino MSM to determine circumstances for HIV infection. Informed by Syndemics Theory, we examine behavioral, biological, and contextual factors associated with HIV infection for Latino MSM. METHODS: Risk assessment and HIV testing data were analyzed for all initially HIV-negative, Latino MSM (n = 3,111) visiting a community-based clinic in Los Angeles, California from January 2009 to June 2014. Survival analyses were used to determine characteristics of Latino MSM who became HIV-positive during the study timeframe. RESULTS: Similar to previous studies of MSM, self-reported history of Chlamydia, Gonorrhea and/or Syphilis (aHR: 1.97; CI: 1.28-3.04), receptive CAI (aHR: 1.7; CI: 1.16-2.49), and methamphetamine use (aHR: 1.99; CI: 1.15-3.43) predicted HIV infection. In addition, originating from Central America (aHR: 2.31; CI: 1.41-3.79), Latino ethnicity of the last sex partner (aHR: 1.67; CI: 1.16-2.39), and experiencing intimate partner violence (IPV) (aHR: 1.73; CI: 1.13-2.64) were also associated with HIV infection among Latino MSM. CONCLUSIONS: This is the first study to show independent associations between IPV and HIV infection among Latino MSM. This study shows that psychosocial conditions such as IPV fuel HIV incidence among Latino MSM, and psychosocial interventions should be considered to reduce HIV disparities among Latino MSM.

Despite a high prevalence of mental health problems in older, HIV+ adults (aged ≥ 50), few studies have examined the relationship between perceived social support and mental health burdens in this group. In a clinic-based sample of 100 adults, 23% and 29% met criteria for one and more than one mental health burden, respectively. In multivariable binary logistic models, perceived receipt of positive and emotional social support as well as overall support was inversely associated with the presence of mental health burdens. There is a need for additional investigation of how social support can help mitigate mental health burdens among HIV+ older adults.

This study examines how romantic relationship cognitions are associated with changes of condomless anal sex among emerging adult gay and bisexual men. The sample was drawn from four waves of a prospective cohort study ( N = 598; M_age = 18.2). Results suggest that condomless anal sex increased over the emerging adulthood period. Romantic relationship fear was associated with increased receptive condomless anal sex. Perceptions of greater romantic relationship control increased the likelihood of having insertive and receptive condomless anal sex. Findings suggest that romantic relationship cognitions are important to consider when understanding longitudinal changes in condomless anal sex in this population.

PURPOSE: Young sexual minority men smoke at higher rates relative to heterosexual peers. The purpose of this study was to examine correlates of smoking in a sample of young gay, bisexual, and other men who have sex with men (MSM) who might differ from more general and age-diverse samples of sexual minority individuals and, thus, inform tailored approaches to addressing tobacco use within this population. METHODS: Data on smoking status were examined in relation to demographics, mental health, substance use behavior, and psychosocial factors. Using multinomial logistic regression, factors were identified that differentiate current and former smokers from never smokers. RESULTS: In bivariate analysis, smoking status was related to demographic, mental health, substance use, and psychosocial factors. Most significantly, smoking status was associated with school enrollment status, current alcohol and marijuana use, and symptoms of depression. Multivariate modeling revealed that, compared to being a never smoker, the odds of current or former smoking were highest among those currently using either alcohol or marijuana. The odds of both current and former smoking were also higher among those reporting greater levels of gay community affinity. Finally, the odds of being a former smoker were higher for those reporting internalized antihomosexual prejudice. CONCLUSION: This study identifies several factors related to smoking status in a diverse sample of young sexual minority males. These findings should encourage investigations of smoking disparities among younger MSM to look beyond common smoking risk factors in an attempt to understand etiologies that may be unique to this group. Such findings may indicate multiple points of potential intervention aimed at decreasing cigarette smoking within this vulnerable population.

We administered a battery of neurocognitive tests to 100 HIV-positive men and women ages 50 to 70 seeking care at a large Northeastern urban HIV care clinic. Performance on neurocognitive assessments varied by demographic states. Across all assessments, approximately 28% of participants reached the threshold for borderline performance while 13% reached the threshold for impairment. When tests were grouped by domain of neurocognitive functioning, 12% of the sample met the threshold for impairment on executive functioning and 19% for processing speed. The findings demonstrate that neurocognitive declines may vary by domains of functioning, that disparities may exist across subpopulations of the seropositive aging population, and that these challenges may exist even in those actively engaged in HIV care.

Young gay, bisexual, and other men who have sex with men (YMSM) are at increased likelihood of experiencing depression and engaging in condomless sexual behaviors. The goal of the current investigation was to examine the relationship between negative mood and compulsive sexual behavior (CSB) and to assess for their individual and combined influence on sexual risk-taking behavior among a diverse sample of YMSM in New York City (the P18 Cohort Study). We first analyzed sociodemographic, depressive symptoms, CSB, and sexual risk-taking from the cross-sectional data of 509, 18- or 19-year-old YMSM recruited using non-probability sampling. We found a significant positive correlation between CSB and depression and between CSB and frequency of condomless anal sex acts reported over the last 30 days. Multivariate results found that the presence of both depression and CSB contributed to elevated sexual risk-taking among these urban YMSM. Clinical implications include the importance of assessing for CSB when depression is present and vice versa in order to improve HIV prevention. Informed by minority stress theory and syndemic theory, our results suggest that interventions focused on the health of YMSM recognize that mental health and social context all interact to increase physical health vulnerability vis-a-vis sexual behaviors, depression, and CSB. Thus, HIV prevention and intervention programs need to incorporate mental health components and services that address these needs.

Young men who have sex with men (YMSM) may be at greater risk for body dissatisfaction, compared to their heterosexual peers. However, differences within YMSM populations are understudied, precluding the identification of YMSM who are at greatest risk. This study examined body dissatisfaction in a racially/ethnically diverse sample of YMSM ages 18-19 in New York City. Using cross-sectional data from the baseline visit of a longitudinal cohort study of YMSM (N = 591), body dissatisfaction was assessed using the Male Body Attitudes Scale. Three outcomes were modeled using linear regression: (1) overall body dissatisfaction, (2) muscularity dissatisfaction, and (3) body fat dissatisfaction. Covariates in the models included race/ethnicity, sexual orientation, BMI, gay community affiliation, and internalized homonegativity. White YMSM experienced greater body dissatisfaction across the three models. Internalized homonegativity was a statistically significant predictor of dissatisfaction across the three models, though its association with body dissatisfaction was relatively small. The findings point to future avenues of research, particularly qualitative research to explore demographic and cultural nuances in body attitudes among YMSM.

Homelessness and housing instability is a significant public health problem among young sexual minority men. While there is a growing body of literature on correlates of homelessness among sexual minority men, there is a lack of literature parsing the different facets of housing instability. The present study examines factors associated with both living and sleeping in unstable housing among n = 600 sexual minority men (ages 18-19). Multivariate models were constructed to examine the extent to which sociodemographic, interpersonal, and behavioral factors as well as adverse childhood experiences explain housing instability. Overall, 13 % of participants reported sleeping in unstable housing and 18 % had lived in unstable housing at some point in the 6 months preceding the assessment. The odds of currently sleeping in unstable housing were greater among those who experienced more frequent lack of basic needs (food, proper hygiene, clothing) during their childhoods. More frequent experiences of childhood physical abuse and a history of arrest were associated with currently living in unstable housing. Current enrollment in school was a protective factor with both living and sleeping in unstable housing. These findings indicate that being unstably housed can be rooted in early life experiences and suggest a point of intervention that may prevent unstable housing among sexual minority men.

OBJECTIVES: To examine the relationship between sexual violence and transactional sex and assess the impact of social support on this relationship among female transnational migrants in Cape Town, South Africa. METHODS: In 2012 we administered a behavioral risk factor survey using respondent-driven sampling to transnational migrant women aged between 16 and 39 years, born outside South Africa, living in Cape Town, and speaking English, Shona, Swahili, Lingala, Kirundi, Kinyarwanda, French, or Somali. RESULTS: Controlling for study covariates, travel-phase sexual violence was positively associated with engagement in transactional sex (adjusted prevalence ratio [APR] = 1.38; 95% confidence interval [CI] = 1.07, 1.77), and social support was shown to be a protective factor (APR = 0.84; 95% CI = 0.75, 0.95). The interaction of experienced sexual violence during migration and social support score was APR = 0.85 (95% CI = 0.66, 1.10). In the stratified analysis, we found an increased risk of transactional sex among the low social support group (APR = 1.56; 95% CI = 1.22, 2.00). This relationship was not statistically significant among the moderate or high social support group (APR = 1.04; 95% CI = 0.58, 1.87). CONCLUSIONS: Programs designed to strengthen social support may reduce transactional sex among migrant women after they have settled in their receiving communities.

PURPOSE: Among young men who have sex with men (YMSM) few studies have examined the relationship between intimate partner violence (IPV) perpetration versus victimization and sexual behaviors. METHODS: Using data from n = 528 urban YMSM, multinomial logistic regression models were built to examine the distinct relationships between any IPV, victimization, and perpetration with condomless sex in the previous 30 days, controlling for key sociodemographic characteristics. RESULTS: In this sample of YMSM, lifetime experience of any IPV was associated with increased odds of recent condomless oral (adjusted odds ratio [AOR] = 1.81, 95% confidence interval [CI] = 1.21-2.72) and anal receptive sex (AOR= 2.29, 95% CI = 1.22-4.31). IPV victimization was associated with a greater likelihood of condomless receptive anal sex (AOR= 2.12, 95% CI = 1.15-3.93) whereas IPV perpetration was associated with increased odds of condomless receptive (AOR= 2.11, 95% CI = 1.14-3.91) and insertive (AOR= 2.21, 95% CI = 1.06-4.59) anal sex. CONCLUSIONS: Among YMSM, reports of both IPV perpetration and victimization were associated with increased odds of recent condomless sex. These findings indicate that the need for IPV prevention and intervention programs for this new generation of YMSM is highly warranted.
