HIV Prevalence and Sexual Behaviors Among Transgender Women in Tehran, Iran

Abstract

To date, no study has looked at the prevalence of HIV and the high-risk behaviors among transgender women in Iran. Between May 2013 and February 2014, 104 transgender women were recruited for participation in this study. Inclusion criteria consisted of having an official letter from the Tehran Psychiatric Institute, or a well-known psychiatrist, that showed a diagnosis of gender dysphoria and/or completed Gender-Affirming Surgery at least 6 months prior to this study. Of the 104 participants, 2 were diagnosed with HIV, which translates to a HIV prevalence of 1.9%. Condom use with a non-paying partner, casual partner, and paying partner was respectively 39.7%, 34.6%, and 53.3%. A high percentage of transgender women in Tehran engage in high-risk sexual behaviors including condomless receptive anal sex, which is of particular concern given the low rates of HIV testing. Targeted public intervention programs and research are desperately needed for this high-risk group.



Undiagnosed and Untreated HIV Infection Among Persons Who Inject Drugs: Results of Three National HIV Behavioral Surveillance Surveys, San Francisco, 2009–2015

Abstract

We examined three waves of National HIV Behavioral Surveillance surveys of persons who inject drugs (PWID) in San Francisco to assess meeting UNAIDS 90–90–90 targets. Diagnosis of PWID living with HIV increased from 64.4% in 2009 to 80.5% in 2015. Antiretroviral treatment among those diagnosed did not improve (63.8% in 2009, 62.9% in 2015). Programs in San Francisco have not achieved the first two UNAIDS targets for PWID by 2015. In a context of a rising opioid epidemic, there is urgent need for increased case finding of PWID living with HIV who are undiagnosed with rapid linkage to treatment.



Estimated Population Size of Men Who Have Sex with Men, San Francisco, 2017

Abstract

Current population size estimates of communities at risk for HIV are needed to adequately plan interventions and care. We update the estimated number of men who have sex with men (MSM) living in San Francisco. Multiple data sources and approaches, including population growth, registered HIV cases, wisdom of the crowd, and a published estimate on the proportion of adults who are MSM were used for estimation. The several estimates were synthesized into a final figure with acceptable bounds using a Bayesian method. We project 69,974 (acceptable bounds 65,523–74,323) MSM are living in San Francisco as of the beginning of 2017. The population of MSM in San Francisco has increased by 19.4% since 2014.



Alcohol Use and Sexual Risk Behavior in Young Women: A Qualitative Study

Abstract

Alcohol use and sexual behavior co-occur frequently in young women, increasing risk for HIV and other sexually transmitted infections. To inform preventive interventions, we used qualitative methods to better understand how women think about the contribution of alcohol use to sexual risk-taking. Young women (N = 25; M = 22.8 years; 64% White) were recruited from a community-based reproductive health clinic to attend focus groups; a semi-structured agenda was used to investigate both a priori explanatory mechanisms as well as participant-driven explanations for the alcohol-sex association. Women reported that alcohol reduced their social anxiety, helped them to feel outgoing and confident, and lowered inhibitions and other barriers to sexual encounters (consistent with alcohol expectancies). During drinking events, women described being less concerned with risks, less discriminating regarding sexual partners, and less likely to insist on safer sex practices (consistent with alcohol myopia). These empirical findings support previous theory-based guidance for tailoring preventive programs for alcohol use and sexual risk reduction for young women.



Approaches to Identify Unknown HIV-Positive Men Who Have Sex with Men in Nairobi, Kenya

Abstract

Kenya has been home to one of the most severe HIV/AIDS epidemics in Sub-Saharan Africa. This persistent epidemic requires interventions tailored to affected populations, particularly men who have sex with men (MSM). Given the resource constraints of many clinics and ecological challenges of Kenya, such as the illegality of sex among MSM, interventions to address HIV must strategically engage this population. This quasi-experimental pilot study of N = 497 sought to explore differences in discovering previously unknown HIV-positive MSM in Nairobi, Kenya. The study used four clinical sites to compare a social and sexual network index testing (SSNIT) strategy compared to traditional HIV screening. Clinics using the SSNIT strategy had significantly higher incidence rates of HIV diagnoses than control clinics (IRR = 3.98, p < 0.001). This study found that building upon the social and sexual networks of MSM may be one promising strategy while discovering critical cases of HIV.



The Association Between Condomless Anal Sex and Social Support Among Black Men Who Have Sex With Men (MSM) in Six U.S. Cities: A Study Using Data from the HIV Prevention Trials Network BROTHERS Study (HPTN 061)

Abstract

We assessed how egocentric (i.e., self-generated descriptions of a person's social contacts) network structure and composition corresponded with reported instances of condomless receptive and insertive anal intercourse with men who were reportedly HIV-infected or of unknown HIV serostatus in a sample of black men who have sex with men (MSM) in six U.S. cities. Ratings showing a higher percentage of network members who provided social participation and medical support were positively associated with reporting condomless sex. There were also significant positive associations between stimulant use and condomless insertive and receptive anal sex. Future research should examine the social processes that underlie these associations and explore ways that social support can affect HIV prevention efforts for black MSM.



Syndemic Classes, Stigma, and Sexual Risk Among Transgender Women in India

Abstract

Syndemic theory could explain the elevated HIV risk among transgender women (TGW) in India. Using cross-sectional data of 300 TGW in India, we aimed to: identify latent classes of four syndemic conditions (Depression-D, Alcohol use-A, Violence victimization-V, HIV-positive status), test whether syndemic classes mediate the association between stigma and sexual risk, and test whether social support and resilient coping moderate the association between syndemic classes and sexual risk. Four distinct classes emerged: (1) DAV Syndemic, (2) AV Syndemic, (3) DV Syndemic, and (4) No Syndemic. TGW in the DAV Syndemic (OR 9.80, 95% CI 3.45, 27.85, p < 0.001) and AV Syndemic classes (OR 2.74, 95% CI 1.19, 6.32, p < 0.01) had higher odds of inconsistent condom use in the past month than the No Syndemic class. Social support significantly moderated the effect of DAV Syndemic class on inconsistent condom use. DAV Syndemic was found to be a significant mediator of the effect of transgender identity stigma on sexual risk. HIV prevention programs among TGW need to: (a) incorporate multi-level multi-component interventions to address syndemic conditions, tailored to the nature of syndemic classes; (b) reduce societal stigma against TGW; and (c) improve social support to buffer the impact of syndemics on sexual risk.



Role of Social Network Sexual Norms and Behaviors on the HIV Sexual Risk Behaviors of People Who Inject Drugs in HPTN 037

Abstract

This study examined the effect of social network descriptive sexual norms and behaviors on the sexual behaviors of people who inject drugs (PWID). Data from HPTN037 of 232 PWID (egos) and 464 network members (alters) were used in multilevel multivariate logistic regression models. Egos whose alters reported multiple sex partners had greater odds of multiple sex partners (aOR 2.20, 1.13–4.29). Egos' norms of condomless sex with primary (aOR 2.67, 1.15–6.17) and casual (aOR 2.38, 1.01–5.59) partners and egos' norms of giving (aOR 5.52, 1.87–16.25) and receiving (aOR 7.38, 1.34–40.66) money/drugs for sex were associated with the egos' respective behaviors. History of sex between an ego and alter was not associated with increased influence of alters' norms and behaviors on egos' sexual behavior. Findings provide support for developing interventions that target descriptive norms and selective network behavioral characteristics to decrease sexual HIV risk behavior among PWID.



The Intersection of HIV, Social Vulnerability, and Reproductive Health: Analysis of Women Living with HIV in Rio de Janeiro, Brazil from 1996 to 2016

Abstract

Comprehensive care for sexual and reproductive health (SRH) and social needs for women living with HIV remains limited globally. We aimed to assess trends in baseline sociodemographic, clinical, sexual, and reproductive characteristics among a cohort of HIV-infected women in Rio de Janeiro from 1996 to 2016. Participants were stratified into four time periods based on year of enrollment; we compared cross-sectional data from each period. Of 1361 participants (median age 36), most were black or mixed race (60.1%), unemployed (52.1%), and without secondary education (54%). Adolescent pregnancy was common (51.5%), and 18.3% reported sexual debut at < 15 years old. Nearly half (45.2%) had < 5 lifetime sexual partners, yet prior syphilis and oncogenic human papillomavirus prevalence were 10.9% and 43.1%, respectively. Lifetime prevalence of induced abortion was 30.3%, and 16% used no contraceptive method. Future research should explore interactions between social vulnerability, HIV, and poor SRH outcomes and healthcare models to alleviate these disparities.



Dual Unsafe Injection and Sexual Behaviors for HIV Infection Among People Who Inject Drugs in Iran

Abstract

We used two national surveys (2010: N = 1597; 2013: N = 1057) of people who inject drugs (PWID) in past-month to assess the prevalence and population size of PWID with either safe or unsafe injection and sex behaviors, overall and by HIV status. In 2013, only 27.0% (vs. 32.3% in 2010) had safe injection and sex, 24.6% (vs. 23.3% in 2010) had unsafe injection and sex, 26.4% (vs. 26.5% in 2010) had only unsafe injection, and 22.0% (vs. 18.0% in 2010) had unsafe sex only. Among HIV-positive PWID in 2013, only 22.1% (~ 2200 persons) had safe injection and sex, 14.2% (~ 1400 persons) had unsafe injection and sex, 53.1% (~ 5200 persons) had unsafe injection, and 10.6% had unsafe sex (~ 1100 persons). Among HIV-negative PWID in 2013, only 27.5% (~ 22,200 persons) had safe injection and sex, 25.9% (~ 20,900 PWID) had unsafe injection and sex, 23.2% (~ 18,700 persons) had unsafe injection, and 23.3% (~ 18,800 persons) had unsafe sex. HIV-positive and -negative PWID in Iran continue to be at risk of HIV acquisition or transmission which calls for targeted preventions services.
