RÉSUMÉ

HIV stigma is a social determinant of health that can influence multiple health outcomes, including adherence to antiretroviral therapy (ART), engagement in HIV care, and viral suppression levels in people with HIV (PWH). In Peru, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW), stigma may play an important role in healthcare engagement. To understand the relationship between stigma and two outcome variables, ART adherence and engagement in HIV care in 400 MSM and TGW, we assessed factors from the Behavioral Model for Vulnerable Populations at two HIV clinics that tailor services for sexual and gender minorities. While some predisposing, need, and enabling resource factors were associated with optimal (≥ 90%) ART adherence or engagement in HIV care, none of the stigma subscales were correlated, suggesting that when LGBTQ-affirming care is provided to MSM/TGW, stigma may not influence HIV-related outcomes.


RESUMEN: El estigma hacia el VIH es un determinante social de la salud que puede influir en múltiples desenlaces, incluyendo la adherencia a la terapia antirretroviral (TAR), el compromiso con la atención del VIH y los niveles de supresión viral en personas viviendo con VIH (PVV). En el Perú, donde la epidemia del VIH se concentra en hombres que tienen sexo con hombres (HSH) y mujeres transgénero (MT), el estigma puede desempeñar un papel importante en el compromiso con la atención médica. Para comprender la relación entre el estigma y dos variables de resultado, la adherencia al TAR y el compromiso con la atención del VIH en 400 HSH y MT, evaluamos factores del Modelo de Comportamiento para Poblaciones Vulnerables en dos clínicas de VIH que adaptan sus servicios para minorías sexuales y de género. Si bien algunos factores predisponentes, de necesidad y de recursos habilitantes se asociaron con una adherencia óptima (≥ 90%) al TAR o al compromiso con la atención del VIH, ninguna de las sub-escalas de estigma estuvieron correlacionadas, sugiriendo que cuando se brinda atención que afirma a la comunidad LGBTQ a HSH/MT, el estigma puede no influir en los desenlaces relacionados con el VIH.

RÉSUMÉ

Characterization of HIV risk factors among transwomen and men who have sex with men (MSM) should be assessed separately and independently. However, due to several constraints, these populations continue to be conflated in clinical research and data. There are limited datasets globally powered to make such comparisons. The study aimed to use one of the largest surveys of transwomen and MSM in Latin America to determine differences in HIV risk and related correlates between the two populations. Secondary data analysis was completed using a cross-sectional biobehavioral survey of 4413 MSM and 714 transwomen living in Perú. Chi Square analysis of selected HIV correlates was conducted to examine differences between transwomen and MSM. Additionally, stratified binary logistic regression was used to split data for further comparative analyses of correlates associated with transwomen and MSM separately. HIV prevalence among transwomen was two-fold greater than among MSM (14.9% vs. 7.0%, p<0.001). Transwomen had a higher prevalence of most HIV risk factors assessed, including presence of alcohol dependence (16.4% vs. 19.0%; p < .001) and drug use in the past 3 months (17.0% vs. 14.9%). MSM were more likely to use marijuana (68.0% vs. 50.0%, p < .001), and transwomen were more likely to engage in inhaled cocaine use (70.0% vs. 51.1%, p < .001). The regression exposed differences in correlates driving sub-epidemics in transwomen vs. MSM, with a trend of substance use increasing HIV risk for transwomen only. Transwomen were more likely to be HIV-infected and had different risk factors from MSM. Targeted prevention strategies are needed for transwomen that are at highest risk. Additionally, further research is needed to determine if these observations in Perú regarding substance use patterns and the role of substance use in HIV risk relate to other trans populations globally.

RÉSUMÉ

BACKGROUND: Alcohol use disorders (AUDs) are common in men who have sex with men (MSM) and transgender women (TGW) in Peru and undermine antiretroviral therapy (ART) adherence. Oral naltrexone (NTX) is an evidence-based treatment for AUD that has not been assessed in cotreating AUD in MSM/TGW with HIV. SETTING AND DESIGN: A multi-site, randomized, double-blind, placebo-controlled trial among MSM/TGW with AUD and newly diagnosed with HIV in Lima, Peru. METHODS: Newly diagnosed MSM/TGW with HIV and AUD were prescribed a single-treatment regimen of EFV/TDF/FTC from 2014 to 2015 and randomized 2:1 to oral NTX (N = 103) or placebo (N = 53) for 24 weeks. The primary and secondary outcomes were proportion achieving viral suppression (VS: HIV-1 RNA < 400 copies/mL) or maximal viral suppression (MVS: HIV-1 RNA < 40 copies/mL) at 24 weeks. RESULTS: There were no significant differences between the arms in VS (81.6% NTX arm vs 75.5% placebo arm; P = 0.37) or MVS (61.2% NTX arm vs 66.0% placebo arm; P = 0.48). Adherence to study medication was low (mean = 34.6%) overall with only 21.4% of participants meeting recommended adherence levels (≥80% daily doses/month). Participants allocated to NTX had significantly lower adherence compared with placebo for both the first and second 12-week study periods, respectively (44.0% vs 35.2%, P = 0.04; 31.4% vs 35.2%, P = 0.03). CONCLUSIONS: Findings are inconclusive regarding the use of NTX for treatment of AUD in MSM/TGW newly diagnosed with HIV. VS and MVS levels were high irrespective of allocation. Adherence to study medication was low, requiring further exploration of strategies to optimize adherence to NTX as AUD treatment.

RÉSUMÉ

INTRODUCTION: Among men who have sex with men (MSM) and transgender women (TW), stimulant use is high and has been associated with an increased risk of HIV infection, suicide and cardiovascular disease (CVD) mortality. We used epidemic modelling to investigate these intersecting health harms among MSM/TW in Lima, Peru and assess whether they could be mitigated by prioritizing HIV pre-exposure prophylaxis (PrEP) and harm reduction interventions among MSM/TW who use stimulants. METHODS: We adapted a dynamic model of HIV transmission among MSM/TW in Lima to incorporate stimulant use and increased HIV risk, suicide and CVD mortality. Among 6% to 24% of MSM/TW using stimulants (mostly cocaine), we modelled an increased risk of unprotected anal sex (RR = 1.35 [95%CI: 1.17 to 1.57]) obtained from local data, and increased risk of suicide (SMR = 6.26 [95%CI: 2.84 to 13.80]) and CVD (SMR = 1.83 [95%CI: 0.39 to 8.57]) mortality associated with cocaine use based on a global systematic review. We estimated the proportion of health harms occurring among MSM/TW who use stimulants in the next year (01-2020/01-2021). We also investigated the 10-year impact (01-2020/01-2030) of: (1) PrEP prioritization for stimulant-using MSM/TW compared to random allocation, and (2) integrating PrEP with a theoretical intervention halving stimulant-associated risk. RESULTS: MSM/TW in Lima will experience high HIV incidence, suicide mortality and CVD mortality (1.6/100 py, and 0.018/100 py, 0.13/100 py respectively) in 2020. Despite stimulant using MSM/TW comprising an estimated 9.5% (95%CI: 7.8 to 11.5) of all MSM/TW, in the next year, 11% 95%CI (i.e. 2.5% to 97.5% percentile) 10% to 13%) of new HIV infections, 39% (95%CI: 18% to 60%) of suicides and 15% (95%CI: 3% to 44%) of CVD deaths could occur among this group. Scaling up PrEP among all stimulant using MSM/TW could prevent 19% (95%CI: 11% to 31%) more HIV infections over 10 years compared to random allocation. Integrating PrEP and an intervention to halve stimulant-associated risks could reduce new HIV infections by 20% (95%CI: 10% to 37%), suicide deaths by 14% (95%CI: 5% to 27%) and CVD deaths by 3% (95%CI: 0% to 16%) over a decade. CONCLUSIONS: MSM/TW who use stimulants experience a disproportionate burden of health harms. Prioritizing PrEP based on stimulant use, in addition to sexual behaviour/gender identity criteria, could increase its impact. Integrated substance use, harm reduction, mental health and HIV care among MSM/TW is needed.

RÉSUMÉ

HIV disproportionately affects men who have sex with men (MSM) and transgender women (TW). These populations use alcohol more heavily than the general population, and alcohol use disorders (AUDs) are more prevalent among them. Naltrexone (NTX) has documented efficacy and safety as a medication-assisted therapy for AUD. Its use has not been well-examined in persons with HIV (PWH) newly initiating antiretroviral therapy (ART) where the possibility of hepatotoxicity may be increased when initating multiple new medications. This study assessed the safety of oral NTX treatment (50 mg daily) initiated concomitantly with antiretroviral therapy (ART) in a double-blind randomized placebo-controlled trial of NTX in MSM/TW in Lima, Peru among MSM and TW with AUD (AUDIT score ≥ 8). We analyzed adverse event data from ART-naïve participants (N = 155) who were randomized (2:1) to initiate ART plus NTX (N = 103) or ART plus placebo (N = 52). Participants were monitored for 24 weeks while taking ART plus NTX/placebo, followed by 24 weeks receiving ART alone. Over 48 weeks, 135 grade 2 or 3 adverse events were reported, resulting in 1.3 clinical adverse events per participant equally represented in both treatment and placebo arms. Two serious adverse events occurred among two participants receiving NTX; neither was attributed to the study medication. No significant differences were found in the proportion of subjects reporting any adverse events between treatment arms across all time-points. These results suggest NTX is safe in MSM/TW PWH with AUD newly initiating ART, as no excess of clinical adverse events or transaminase elevation was associated with NTX use.

RÉSUMÉ

Purpose Little is known about the health status of prisoners in low-income countries. In Haiti, prisons typically lack adequate medical care, clean water and food, though some prisoners receive additional food from visitors. The purpose of this paper is to characterize the physical and mental health of Haitian prisoners in three select prisons and examine the effects of having visitors and length of detention on health status. The authors hypothesized that prisoners with more visitors and shorter detention times would have better overall health status. Design/methodology/approach The authors conducted a cross-sectional study of 290 male inmates in three regional prisons in Haiti. Data were collected on prisoners' sociodemographic characteristics, number of visitors, length of detention, body mass index (BMI), self-reported physical and mental health status, and food insecurity. Findings Overall, prisoners at all three prisons had poor health outcomes. Prisoners with more visitors were significantly less likely to be underweight and more likely to have a higher BMI, better self-reported physical function and lower levels of food insecurity. The length of incarceration was negatively associated with physical function and self-rated health, but positively associated with BMI. These results suggest that prisoners who do not receive supplemental food from visitors are at increased risk for food insecurity and poor nutritional and physical health status. Originality/value These findings demonstrate the importance of supplemental food from visitors in stabilizing prisoner health in Haiti and emphasize the need for the provision of adequate nutrition to all prisoners. This study also suggests that policies that reduce incarceration times could improve health status among prisoners.

RÉSUMÉ

In Peru, HIV is concentrated among men who have sex with men (MSM) and transgender women (TGW). Between June 2015 and August 2016, 591 HIV-positive MSM and TGW were recruited at five clinical care sites in Lima, Peru. We found that 82.4% of the participants had achieved viral suppression (VS; VL < 200) and 73.6% had achieved maximal viral suppression (MVS; VL < 50). Multivariable modeling indicated that patients reporting transportation as a barrier to HIV care were less likely to achieve VS (aOR = 0.47; 95% CI = 0.30-0.75) and MVS (aOR = 0.56; 95% CI = 0.37-0.84). Alcohol use disorders were negatively associated with MVS (aOR = 0.62; 95% CI = 0.30-0.75) and age was positively associated with achieving MVS (aOR = 1.29; 95% CI = 1.04-1.59). These findings underscore the need for more accessible HIV care with integrated behavioral health services in Lima, Peru.

RÉSUMÉ

PURPOSE: Globally, transgender women (TGW) experience a high burden of adverse health outcomes, including a high prevalence of HIV and sexually transmitted infections (STIs) as well as psychiatric disorders and substance use disorders. To address gaps in HIV research in Peru focused specifically on TGW, this study presents characteristics of a sample of HIV-positive TGW and identifies factors associated with viral suppression. METHODS: Between June 2015 and August 2016, 50 HIV-positive TGW were recruited in Lima, Peru. Multivariable logistic regression was used to identify factors associated with viral suppression (<200 copies/mL) among the TGW. RESULTS: Among TGW, 85% achieved viral suppression. Approximately half (54%) reported anal sex with more than five partners in the past 6 months, 38% reported sex work, 68% had not disclosed their HIV status to one or more of their partners, and 38% reported condomless sex with their last partner. The prevalence of alcohol use disorders was high (54%), and 38% reported use of drugs in the past year. Moderate-to-severe drug use significantly reduced odds of achieving viral suppression (adjusted odds ratio 0.69; 95% confidence interval: 0.48-0.98). CONCLUSION: Our findings highlight the need for integrated treatment for substance disorders in HIV care to increase the viral suppression rate among TGW in Lima, Peru.

RÉSUMÉ

Background Syphilis in Peru is heavily concentrated in men who have sex with men (MSM) and transgender women (TGW). The aim of the present study was to understand the risk factors for active syphilis infection among MSM and TGW in Peru. METHODS: Independent correlates suggestive of active syphilis infection were examined to better understand risk factors for syphilis in MSM and TGW, with separate analyses conducted based on location and among TGW. In 2011, 5101 MSM and TGW completed both self-report surveys and HIV and syphilis testing in five Peruvian cities. RESULTS: Overall, 261 (5.1%) MSM and TGW met the criteria for active syphilis, with higher prevalence in Lima than elsewhere (7.0% vs 3.0%) and in TGW than in MSM (10.7% vs 4.2%). Significant independent correlates of active syphilis infection differed greatly by location. In Lima, they included being HIV-infected (aware or unaware of status), being a TGW, being a high school graduate, engaging in receptive anal intercourse, no recent sex with a female partner and having had any symptomatic sexually transmissible infection, including syphilis, in the previous 6 months. Outside Lima, the independent correlates included being HIV-infected and unaware of status, engaging in recent sex work, no recent sex with a female partner and age 35-44 years. Among TGW, independent correlates of active syphilis included being HIV-infected (aware or unaware of status), a recent syphilis diagnosis in the previous 6 months and recent drug use. CONCLUSION: The findings of the present study support the need not only for combined HIV and syphilis screening, but also for increased screening and treatment of syphilis in MSM and TGW populations. Stratified analyses suggest different syphilis epidemics throughout the country and in TGW, yet being HIV-infected and aware were consistently associated with active syphilis, suggesting higher syphilis risk in HIV-infected MSM and TGW.

RÉSUMÉ

Neurocognitive impairment (NCI) has been associated with poor clinical outcomes in various patient populations. This study used exploratory factor analysis (EFA) to examine the factor structure of the existing 95-item Neuropsychological Impairment Scale (NIS) to create a suitable NCI screening instrument for people living with HIV (PLH). In Lima, Peru, 313 HIV-positive men who have sex with men (MSM) and transgender women (TGW) prescribed antiretroviral therapy (ART) completed the NIS using computer-assisted self-interviews (CASI). The EFA used principal axis factoring and orthogonal varimax rotation, which resulted in 42 items with an 8-factor solution that explained 51.8% of the overall variance. The revised, 8-factor, Brief Inventory of Neurocognitive Impairment for Peru (BINI-P) showed a diverse set of factors with excellent to good reliability (i.e., F1 α = 0.92 to F8 α = 0.78). This EFA supports the use of the BINI-P to screen for NCI among Spanish-speaking, HIV-positive MSM and TGW. Future research should examine the effectiveness of the BINI-P in detecting NCI in clinical care settings and the impact of NCI on HIV health-related outcomes, including linkage and retention in care, ART adherence and HIV risk behaviors.

RÉSUMÉ

BACKGROUND: Peruvian men who have sex with men (MSM) and transgender women (TGW) experience the double burden of a highly concentrated HIV epidemic with a high prevalence of alcohol use disorders (AUDs). Recent research has associated both with risky sexual behaviors, including unprotected sex, having multiple sexual partners, engaging in sex work, having recent sexually transmitted infections, and having HIV-infected partners. AUDs have also been associated in MSM/TGW with being unaware of HIV+ status. OBJECTIVES: This study aims to further examine issues associated with alcohol consumption, HIV infection, and risk behaviors in a qualitative analysis of focus groups conducted with MSM/TGW in Peru. METHODS: A total of 26 MSM/TGW participants with AUDs participated in three semi-structured focus groups in Lima, Peru. Content analysis was facilitated by software, and specific themes were elucidated. RESULTS: Participants described their drinking patterns, including the types of alcoholic drinks they consumed. They depicted drinking frequently and over multiple-day sessions. Problematic drinking behaviors were described, as well as the perceived characteristics of alcohol dependence. Interestingly, HIV-infected participants who were prescribed antiretroviral therapy did not believe that their drinking affected their medication adherence. These insights can aid in the design of future interventions aiming to reduce problematic drinking as well as HIV-related risk behaviors and, subsequently, HIV incidence. CONCLUSIONS: Peruvian MSM/TGW exhibit problematic drinking, which may be associated with risky sexual behaviors and HIV transmission. Interest in reducing alcohol consumption was high, suggesting the need for targeted behavioral and pharmacological interventions.

RÉSUMÉ

In Peru, the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW). Multiple studies correlate alcohol use disorders (AUDs) with risky sexual behaviors among Peruvian MSM. Qualitative research was used to inform a clinical trial on the acceptability of medication-assisted therapies to assist management of AUDs and improve antiretroviral therapy (ART) adherence among MSM/TGW in Peru. Three focus groups involving HIV-infected or HIV-uninfected MSM/TGW ( n = 26) with AUDs (AUDIT ≥ 8) were transcribed, translated from Spanish into English, and analyzed using thematic content analysis. Despite having an AUD, participants considered themselves "social" drinkers, minimized their drinking behaviors, and differed about whether or not alcohol problems could be treated. Participants expressed skepticism about medication for treating AUDs. Three concepts emerged as necessary components of a treatment program for alcohol problems: cost, family support, and the potential to drink less alcohol without attaining total abstinence. This study reveals important areas of education to increase potential acceptability of a medication for treating AUDs among MSM/TGW. Given the social conditions and knowledge base of the participants, medication-assisted therapies using naltrexone may be a beneficial strategy for MSM with AUDs.

RÉSUMÉ

INTRODUCTION AND AIMS: Alcohol use disorders are highly prevalent among men who have sex with men (MSM) in Peru, where the HIV epidemic is concentrated 100-fold greater among MSM than in the general population. Drinking expectancies have been associated with the intent to drink and engage in high-risk behaviours. Assessing them in this population may uncover attractive intervention targets that in turn can be used to reduce problematic drinking and risky sexual behaviours. The drinking expectancy questionnaire for MSM (DEQ-MSM) was developed to accurately measure drinking expectancies, specifically among MSM. This study aimed to validate this instrument for the first time in Spanish, in South America and among MSM in Peru. DESIGN AND METHODS: To validate the DEQ-MSM among Spanish-speaking MSM in Peru, we used exploratory and confirmatory factor analysis in a sample of 5148 MSM, including 700 transgender women (TGW). RESULTS: Exploratory factor analysis showed a two-factor structure to the Spanish version of the DEQ-MSM (DEQ-MSM-S), which was similar for MSM and TGW. The reliability of the translated DEQ-MSM was excellent (α = 0.91). DISCUSSION AND CONCLUSIONS: The DEQ-MSM-S was shown to be highly reliable in a large population of Peruvian MSM and TGW. This short instrument can be effectively integrated into research or clinical practice, in order to identify alcohol-consuming, high-risk MSM, who can then be directed for further screening and/or intervention. Future research should aim to associate the Spanish version of the DEQ-MSM with risky sexual behaviours among this population, in order to identify potential intervention targets.

RÉSUMÉ

Although there have been significant reductions in the number of new HIV infections globally from 2009 to 2013, incidence remains unacceptably high for persons who use drugs. In many settings, women and girls who inject drugs (WWID) with HIV/AIDS experience poor treatment access, including evidence-based practices like antiretroviral therapy and drug treatment. Medication-assisted therapies (MAT) for substance use disorders are especially inaccessible, which in their absence, increases HIV transmission risk. Irrespective of setting or culture, drug treatment using MAT is not only effective but also cost-effective at reducing opioid use and linked injection and sexual risks. Data presented here for WWID address their access to MAT for opioid addiction and to treatments being developed that address the relationship, family, and vocational needs of this group. The most glaring finding is that globally, WWID frequently are excluded in surveys or studies with an impressive lack of disaggregated data by gender when surveying access to MAT­even in wealthy countries. Despite this, there have been some striking improvements in implementing drug treatment as prevention, notably in Iran and China. Still, real barriers remain for women and girls to accessing drug treatment, other harm reduction services, and antiretroviral therapy. Development and/or implementation of interventions that facilitate women and girls engaging in drug treatment that address their roles within society, work, and family/relationships, and outcome evaluation of these interventions are crucial.

RÉSUMÉ

The HIV epidemic in Peru is concentrated among men who have sex with men (MSM). Given that MSM have been documented as early adopters of emerging technology, we examined communication technology access and utilization, and mobile health (mHealth) acceptance among Peruvian MSM and transgender women (TGW) in order to gauge opportunities for mHealth-enabled HIV interventions. A convenience sample of 359 HIV-infected MSM and TGW recruited from three sites in Lima, Peru completed standardized assessments of alcohol use disorders (AUDs), risky sexual behavior, and antiretroviral therapy (ART) adherence along with self-constructed measures of communication technology access and utilization, and mHealth acceptance. Most participants (86%) had daily access to any cell phone, including smartphones (30%). The most frequent communication activities were receiving and making calls, and receiving and sending text messages using cell phones. On a 5-point Likert scale, participants expressed interest in using mHealth for medication reminders (M = 3.21, SD = 1.32) and engaging in anonymous online interactions with health professionals to discuss HIV-related issues (M = 3.56, SD = 1.33). Importantly, no significant differences were found in communication technology use and mHealth acceptance among participants with AUDs, depression, and suboptimal ART adherence, all of which are associated with poor HIV treatment outcomes. Findings show support for implementing mHealth-based intervention strategies using cell phones to assess and reduce HIV-risk behaviors among HIV-infected MSM and TGW.

RÉSUMÉ

As international guidelines increase access to antiretroviral therapy (ART) globally, ART adherence becomes increasingly important to achieve HIV treatment as prevention (TasP) goals. In the concentrated HIV epidemic among men who have sex with men (MSM) and transgendered women (TGW) in Lima, Peru, the independent correlates of ART nonadherence were examined to inform treatment intervention priorities. Cross sectional survey of HIV-infected MSM and TGW who are engaged in clinical care in Lima, Peru. From June to August 2012, 302 HIV-infected Peruvian MSM/TGW from three clinical care sites were recruited using convenience sampling to participate in a cross-sectional computer-assisted adherence survey. Several standardized screening measures associated with ART nonadherence were examined in order to determine the independent correlates of optimal (≥90%) and perfect (100%) adherence, which were assessed using logistic regression. Of the 302 participants recruited, 263 (87.1%) were prescribed ART. Among those prescribed ART, 229 (87.1%) reported optimal and 146 (55.5%) reported perfect adherence. The prevalence of alcohol use disorders (AUD; 43.2%), alcohol dependence (5.3%), recent drug use (6.0%), and depression (44.5%) was high, and most participants had some evidence of neurocognitive impairment. Meeting criteria for having an AUD and depression were collinear (p < 0.001). On multivariate analysis, having an AUD was inversely related and the only independent correlate of optimal (AOR = 0.427; 95% CI = 0.187-0.976) and perfect (AOR = 0.552; 95% CI = 0.327-0.930) ART adherence. AUDs are highly prevalent among Peruvian HIV-infected MSM and contribute significantly to ART nonadherence. These findings support the need for screening and treating underlying AUDs. In order to meet HIV TasP goals, evidence-based strategies targeting AUDs are likely to directly improve ART adherence and indirectly improve overall individual health, HIV treatment engagement, and reduce transmission to sexual partners among this vulnerable and disproportionally affected population.

RÉSUMÉ

Engagement in sexual activity among Haitian youth is increasing. The present cross-sectional study examined the independent correlates of sexual risk behaviors among 200 (108 male/92 female) 13-18 year-old adolescents in Port-au-Prince, Haiti using face-to-face interviews. The majority (60.0 %) had engaged in sexual intercourse. Multivariate modeling found males to be 3.52 times more likely to have had sex, 5.42 times more likely to report sexual debut before age 14, 9.75 times more likely to have >1 sexual partner, and 3.33 times more likely to not have used a condom during last sex. Adolescents living with parents, grandparents, aunts or uncles were less likely to report having unprotected sex compared with those without adult family members in the home (AOR range 0.26-0.51). The high prevalence of risky sex among males and the protective influence of stable family cohesiveness have important implications for HIV prevention efforts.

RÉSUMÉ

This study compared the correlates of HIV risk among men who have sex with men (MSM) with newly diagnosed versus previously known HIV infection among 5,148 MSM recruited using modified snowball sampling in 5 Peruvian cities. Participants, if age ≥18 years and reporting sex with a male in the previous 12 months, underwent standardized computer-assisted risk assessments and HIV and syphilis testing. Overall, 420 (8.2 %) participants tested HIV seropositive, most of whom (89.8 %) were unaware of their HIV status. Compared to those who knew themselves to be HIV-infected, multivariate logistic regression demonstrated that unprotected anal intercourse at last encounter [AOR = 2.84 (95 % CI 1.09-7.40)] and having an alcohol use disorder (AUD) [AOR = 2.14 (95 % CI 1.01-5.54)] were independently associated with a newly diagnosed HIV infection. Being unaware of being HIV-infected was associated with high-risk sexual behaviors and AUDs, both of which are amenable to behavioral and medication-assisted therapy interventions.

RÉSUMÉ

OBJECTIVE: To provide an account of published literature on the association between alcohol use and sexual risk-taking, focusing on Latin America. METHODS: A search of MEDLINE, Embase, Web of Science, LILACS, and Cochrane databases identified 561 unique articles. After excluding those that were not directly relevant, 30 studies were retained for review. RESULTS: Twenty-seven studies showed direct or indirect associations between alcohol abuse and unprotected/risky sex. Three studies, however, showed no association between these variables, suggesting that the public health message of safer sex may have been effective. CONCLUSIONS: Further research is needed to identify factors and behaviors that could be modified to reduce the association between alcohol use disorders and risky sexual behavior.


OBJETIVO: Proporcionar una descripción de la bibliografía sobre la asociación entre el consumo de alcohol y la toma de riesgos sexuales, con foco en América Latina. MÉTODOS: Una búsqueda en las bases de datos MEDLINE, Embase, Web of Science, LILACS y Cochrane permitió seleccionar 561 artículos singulares. Tras excluir los que no eran pertinentes, se retuvieron 30 estudios para su análisis. RESULTADOS: Veintisiete estudios revelaron asociaciones directas o indirectas entre el consumo excesivo de alcohol y el sexo sin protección o de riesgo. Sin embargo, tres estudios no mostraron ninguna asociación entre estas variables, lo que sugiere que las recomendaciones de salud pública en pro de una actividad sexual de menor riesgo podrían haber sido eficaces. CONCLUSIONES: Se requiere llevar a cabo nuevas investigaciones para establecer los factores y los comportamientos que podrían ser objeto de modificación para reducir la asociación entre los trastornos por consumo de alcohol y el comportamiento sexual de riesgo.

RÉSUMÉ

BACKGROUND: Peru's HIV epidemic is concentrated among men who have sex with men (MSM). The contribution of alcohol use disorders (AUDs) to known high-risk behaviors associated with HIV transmission in this context has not been well characterized. METHODS: Between June and October 2011, 5,148 sexually active MSM were recruited using convenience sampling in five cities to participate in a cross-sectional bio-behavioral survey. Five high-risk sexual criteria previously associated with incident HIV infection in this setting were selected a priori as the dependent outcomes. Screening for AUDs used the validated Alcohol Use Disorders Identification Test (AUDIT) and AUDS were stratified by severity. Unadjusted and adjusted odds ratios (AOR) were computed to establish the independent correlates of the five dependent outcomes. RESULTS: The majority (62.8%) of participants met screening criteria for having an AUD, which were independently correlated with each of the following high-risk sexual risk behaviors in the previous 6 months: 1) >5 sexual partners [AOR = 1.76; (1.54-2.02)]; 2) sex with an HIV-infected partner [AOR = 1.29; (1.03-1.62)]; 3) having a sexually transmitted infection [AOR = 1.38; (1.13-1.68)]; 4) being a sex worker [AOR = 1.61; (1.40-1.87)]; and 5) unprotected sex during last encounter [AOR = 1.22; (1.09-1.38)]. Recent drug use was also correlated with having >5 sexual partners [AOR = 1.42 (1.19-1.71)], sex work [AOR = 1.97 (1.63-2.39)] and unprotected sex during last encounter [AOR = 1.31 (1.11-1.54)]. For each dependent variable, the association with AUDs significantly increased with increasing AUD severity. CONCLUSIONS: AUDs are highly prevalent among MSM in Peru and are associated with increased HIV risk-taking behaviors that are associated with HIV transmission. Strategies that target problematic drinking such as medication-assisted therapy, behavioral counseling and structural interventions could potentially reduce risky behaviors and ultimately reduce HIV transmission among MSM in Peru.
