Alcohol consumption and risk of incident human immunodeficiency virus infection: a meta-analysis

The relationship between alcohol consumption and risk of HIV in married men in Sub-Saharan Africa

OBJECTIVE

A key factor for incidence of HIV is alcohol consumption. It impacts judgment and the probability to overlook risk-relevant information, which creates a pathway to reduced adherence to biomedical prevention and engagement in condomless sex. We strengthen the understanding of the link between alcohol consumption and risk of HIV among married men in sub-Saharan Africa (SSA), as we use comprehensive population-level data to provide robust evidence with high external validity.

DESIGN

Cross-sectional data analysis.

METHODS

Based on data from Demographic and Health Surveys (DHS) from 20 countries and over 30 000 observations, a minimally and a fully adjusted model with country fixed effects examined the relationship between the men's alcohol consumption (observed by wife) and HIV status (blood test) while accounting for survey weights and controlling for potential confounders.

RESULTS

The data comprised a total of 35 108 men. Minimally adjusted [risk ratio (RR) 1.25; 95% confidence interval (CI) 1.14-1.37; P  < 0.001] and fully adjusted (RR 1.26; 95% CI 1.15-1.38; P  < 0.001) models showed a positive association between the men's alcohol consumption and HIV status. Two sensitivity analyses confirmed the association.

CONCLUSION

In line with previous experimental studies and theoretical framework, this study confirms a risk relationship between alcohol consumption and HIV. Thus, modern HIV/AIDS programs must continue to address the relationship in implementation of prevention and treatment programs.

Alarming patterns of moderate and high-risk alcohol use among transgender women in Goiás, Central Brazil

Background

Scant studies have examined alcohol consumption among transgender women in Latin America. This cross-sectional study estimated the prevalence and associated factors of risky alcohol use among transgender women in Goiás, a state located in the center of Brazil.

Methods

Participants were 440 transgender women (median age = 35 years, interquartile range = 9) recruited through respondent-driven sampling. All participants were interviewed about sociodemographic characteristics, violence, and risk behavior. Alcohol use was assessed using the alcohol use disorders identification test (AUDIT). An AUDIT score greater than or equal to eight was considered as risky alcohol consumption. Logistic regression analysis was used to examine predictors of risky alcohol use, and p-values <0.05 were considered significant.

Results

The majority were young, single, sex workers. Most transgender women had used alcohol in the previous year (85.7%), and more than half (56.6%) reported binge drinking and risky alcohol consumption (60.2%). There was a high overlap between sexual behavior, drugs, and alcohol use. Using alcohol during sex (adjusted odds ratio [aOR]: 2.9; 95% confidence interval [CI]: 1.7-4.8), cocaine/crack use (aOR: 2.3; 95% CI: 1.5-3.7) and having a drug user as a sexual partner (aOR: 2.9; 95% CI: 1.5-5.9) were independently associated with risky alcohol consumption.

Conclusion

Alcohol consumption was highly prevalent, and drugs seem to play an important role in risky alcohol consumption among transgender women Goiás. These findings support stakeholders to promote intervention strategies to reduce this pattern of alcohol consumption and reduce the burden of substance use disorders among transgender women.

Alcohol Promotes Lipogenesis in Sebocytes-Implications for Acne

The oral consumption of alcohol (ethanol) has a long tradition in humans and is an integral part of many cultures. The causal relationship between ethanol consumption and numerous diseases is well known. In addition to the well-described harmful effects on the liver and pancreas, there is also evidence that ethanol abuse triggers pathological skin conditions, including acne. In the present study, we addressed this issue by investigating the effect of ethanol on the energy metabolism in human SZ95 sebocytes, with particular focus on qualitative and quantitative lipogenesis. It was found that ethanol is a strong trigger for lipogenesis, with moderate effects on cell proliferation and toxicity. We identified the non-oxidative metabolism of ethanol, which produced fatty acid ethyl esters (FAEEs), as relevant for the lipogenic effect-the oxidative metabolism of ethanol does not contribute to lipogenesis. Correspondingly, using the Seahorse extracellular flux analyzer, we found an inhibition of the mitochondrial oxygen consumption rate as a measure of mitochondrial ATP production by ethanol. The ATP production rate from glycolysis was not affected. These data corroborate that ethanol-induced lipogenesis is independent from oxygen. In sum, our results give a causal explanation for the prevalence of acne in heavy drinkers, confirming that alcoholism should be considered as a systemic disease. Moreover, the identification of key factors driving ethanol-dependent lipogenesis may also be relevant in the treatment of acne vulgaris.

Substance Use and Misuse among Sexual and Gender Minority Communities Living in Former Soviet Union Countries: A Scoping Review

Objectives

We reviewed literature examining substance use among sexual and gender minorities (SGM) living in the former Soviet Union (USSR) nations.

Methods

Searches were conducted across five databases (PubMed, SocINDEX, CINAHL, PscyInfo, LGBTQ + Source) to identify peer-reviewed literature.

Results

Across 19 studies, high hazardous substance use prevalence was documented. Substance use was correlated with (a) sexual health and behaviors and (b) mental wellbeing and the use of other substances.

Conclusion

We discuss minority stress implications and challenges presented by the paucity of evidence in the literature examining substance use among SGM women and SGM living in countries unrepresented in reviewed studies.

Perspectives on unhealthy alcohol use among men who have sex with men prescribed HIV pre-exposure prophylaxis: A qualitative study

Unhealthy alcohol use is a common, often unaddressed behavior associated with increased risk for acquisition of HIV and may also be associated with decreased adherence to oral pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (MSM) living in the United States. To inform future alcohol-reduction interventions among individuals engaging in PrEP care, we sought to explore perspectives on alcohol use, PrEP adherence, and the acceptability of alcohol use treatment options for MSM prescribed oral formulations of PrEP in the Northeastern United States. Between February 2019 and July 2020, we conducted semi-structured interviews with 15 MSM without HIV who were prescribed PrEP and screened positive for unhealthy alcohol use with AUDIT-C ≥ 4 and were receiving care in Providence, Rhode Island or New Haven, Connecticut. Interviews were coded and analyzed using thematic analysis. Three themes emerged: 1) Consequences of fluctuations in drinking 2) Alcohol use negatively impacts health and relationships; and 3) Desire for a multimodal approach to treatment of unhealthy alcohol use. Our findings support the need to raise awareness of potential alcohol-related harms, address the spectrum of unhealthy alcohol use among MSM prescribed PrEP, and the acceptability and preferences for alcohol reduction interventions within PrEP programs.

Risk factors of HIV and variation in access to clean needles among people who inject drugs in Pakistan

We identified key risk factors for HIV among people who inject drugs (PWID) in Pakistan and explored access to free clean needles. Multivariable logistic regression was used to investigate associations between HIV prevalence and demographic, behavioral, and socio-economic characteristics of PWID. Data came from the Government of Pakistan's Integrated Biological and Behavioral Surveillance (IBBS) Round 5 (2016-17; 14 cities). A secondary analysis investigated associations with reported access to clean needles. Unweighted HIV prevalence among 4,062 PWID (99% male) was 21.0%. Longer injecting duration (Odds ratio [OR] 1.06 [95% confidence interval: 1.02-1.10]; per year), higher injecting frequency (OR 1.67 [1.30-2.13]; per unit increase), and injecting heroin (OR 1.90 [1.11-3.25]) were positively associated with HIV prevalence. There was no association between using a used syringe at last injection and HIV. Having>10 years of education had lower odds of HIV than being illiterate (OR 0.58 [0.35-0.95]). Having a regular sexual partner (OR 0.74 [0.57-0.97]) or paying for sex with the opposite sex (OR = 0.62 [0.45-0.85]) had lower odds of HIV than not. Conversely, PWID paying a man/hijra for sex had higher odds of HIV (OR 1.20 [1.00-1.43]). Receipt of clean needles varied by city of residence (0-97% coverage), whilst PWID with knowledge of HIV service delivery programs had higher odds of receiving clean needles (OR 4.58 [3.50-5.99]). Injecting behaviors were associated with HIV prevalence among PWID, though risks related to paying for sex remain complicated. Geographical variation in access to clean needles suggests potential benefits of more widely spread public health services.

Substance use and variation in sexual partnership rates among young MSM and young transgender women: Disaggregating between and within-person associations

BACKGROUND

Substance use has been extensively linked to sexual behavior and HIV/STI risk among men who have sex with men (MSM) and transgender women (TW). However, the impact of specific substances and on specific partnership types is not well characterized. The current study seeks to estimate the association between specific substances and partnership rates while carefully disaggregating between and within-person associations to characterize the nature of these associations and inform prevention interventions.

METHODS

Using data from a longitudinal cohort (n = 1159) of young MSM (YMSM) and young TW (YTW), we utilized a series of hybrid mixed effect models to estimate the associations between substance use (i.e., heavy episodic drinking [HED], marijuana, cocaine, ecstasy, methamphetamine, poppers, prescription stimulant, prescription painkiller, and prescription depressants) and partnerships (i.e., one-time, casual, and main).

RESULTS

Results from multivariable models indicated people using substances had higher one-time (HED, poppers) and casual (HED, methamphetamine, poppers) partnership rates. In addition, participants reported higher rates of one-time (HED, ecstasy, methamphetamine, poppers) and casual partners (HED, marijuana, cocaine, methamphetamines, poppers) during periods of substance use.

CONCLUSION

These findings confirm that the highest rates of sexual activity occur among YMSM-YTW using substances during periods of substance use. Yet, these findings should caution researchers against simplistic generalizations as these associations differ across substance and partnership types. Efforts to promote the health of MSM-YTW who use substances should carefully consider this complexity as interventions accounting for the unique cultural context of substance use in these populations are most likely to be successful.

Pilot study on the influence of acute alcohol exposure on biophysical parameters of leukocytes

Objective: This pilot study explores the influence of acute alcohol exposure on cell mechanical properties of steady-state and activated leukocytes conducted with real-time deformability cytometry. Methods: Nineteen healthy male volunteers were enrolled to investigate the effect of binge drinking on biophysical properties and cell counts of peripheral blood leukocytes. Each participant consumed an individualized amount of alcohol to achieve a blood alcohol concentration of 1.2 ‰ as a mean peak. In addition, we also incubated whole blood samples from healthy donors with various ethanol concentrations and performed stimulation experiments using lipopolysaccharide and CytoStim™ in the presence of ethanol. Results: Our findings indicate that the biophysical properties of steady-state leukocytes are not significantly affected by a single episode of binge drinking within the first two hours. However, we observed significant alterations in relative cell counts and a shift toward a memory T cell phenotype. Moreover, exposure to ethanol during stimulation appears to inhibit the cytoskeleton reorganization of monocytes, as evidenced by a hindered increase in cell deformability. Conclusion: Our observations indicate the promising potential of cell mechanical analysis in understanding the influence of ethanol on immune cell functions. Nevertheless, additional investigations in this field are warranted to validate biophysical properties as biomarkers or prognostic indicators for alcohol-related changes in the immune system.

Interventions to Reduce Alcohol Use and HIV Risk among Sexual and Gender Minority Populations: a Systematic Review

PURPOSE OF REVIEW

Sexual and gender minority (SGM) individuals are diagnosed with HIV at disproportionate rates, and hazardous alcohol use can increase their HIV risk. This review assessed the state of the literature examining interventions for addressing alcohol use and sexual HIV risk behaviors among SGM individuals.

RECENT FINDINGS

Fourteen manuscripts from 2012 to 2022 tested interventions that address both alcohol use and HIV risk behaviors among SGM populations, with only 7 randomized controlled trials (RCTs). Virtually all the interventions targeted men who have sex with men, with none focused on transgender populations or cisgender women. While they demonstrated some evidence of effectiveness in reducing alcohol use and/or sexual risk, the outcomes varied widely between studies. More research is needed that tests interventions in this area, particularly for transgender individuals. The use of larger-scale RCTs with diverse populations and standardized outcome measures are needed to strengthen the evidence base.

An agent-based model of binge drinking, inequitable gender norms and their contribution to HIV transmission, with application to South Africa

BACKGROUND

Binge drinking, inequitable gender norms and sexual risk behaviour are closely interlinked. This study aims to model the potential effect of alcohol counselling interventions (in men and women) and gender-transformative interventions (in men) as strategies to reduce HIV transmission.

METHODS

We developed an agent-based model of HIV and other sexually transmitted infections, allowing for effects of binge drinking on sexual risk behaviour, and effects of inequitable gender norms (in men) on sexual risk behaviour and binge drinking. The model was applied to South Africa and was calibrated using data from randomized controlled trials of alcohol counselling interventions (n = 9) and gender-transformative interventions (n = 4) in sub-Saharan Africa. The model was also calibrated to South African data on alcohol consumption and acceptance of inequitable gender norms. Binge drinking was defined as five or more drinks on a single day, in the last month.

RESULTS

Binge drinking is estimated to be highly prevalent in South Africa (54% in men and 35% in women, in 2021), and over the 2000-2021 period 54% (95% CI: 34-74%) of new HIV infections occurred in binge drinkers. Binge drinking accounted for 6.8% of new HIV infections (0.0-32.1%) over the same period, which was mediated mainly by an effect of binge drinking in women on engaging in casual sex. Inequitable gender norms accounted for 17.5% of incident HIV infections (0.0-68.3%), which was mediated mainly by an effect of inequitable gender norms on male partner concurrency. A multi-session alcohol counselling intervention that reaches all binge drinkers would reduce HIV incidence by 1.2% (0.0-2.5%) over a 5-year period, while a community-based gender-transformative intervention would reduce incidence by 3.2% (0.8-7.2%) or by 7.3% (0.6-21.2%) if there was no waning of intervention impact.

CONCLUSIONS

Although binge drinking and inequitable gender norms contribute substantially to HIV transmission in South Africa, recently-trialled alcohol counselling and gender-transformative interventions are likely to have only modest effects on HIV incidence. Further innovation in developing locally-relevant interventions to address binge drinking and inequitable gender norms is needed.

Alcohol use and associated risk factors among female sex workers in low- and middle-income countries: A systematic review and meta-analysis

Due to its widespread use in the sex work industry, female sex workers (FSWs) in low- and middle-income countries (LMICs) are at high risk of harmful alcohol use and associated adverse health outcomes. Factors associated with harmful alcohol use include violence, mental health problems, drug use, sexual risk behaviors and HIV/STIs. To our knowledge, there has been no quantitative synthesis of FSW alcohol use data to date. This systematic review and meta-analysis aims to provide an estimate of the prevalence of harmful alcohol use among FSWs in LMICs and to examine associations with common health and social concerns. The review protocol was registered with PROSPERO, number CRD42021237438. We searched three electronic databases for peer-reviewed, quantitative studies from inception to 24th February 2021. Studies were selected for inclusion that reported any measure of prevalence or incidence of alcohol use among FSWs aged 18 or older from countries defined as LMIC in accordance with the World Bank income groups 2019. The following study designs were included: cross-sectional survey, case-control study, cohort study, case series analysis, or experimental study with baseline measures for alcohol use. Study quality was assessed with the Center for Evidence-Based Management (CEBMa) Critical Appraisal Tool. Pooled prevalence estimates were calculated for (i) any hazardous/harmful/dependent alcohol use, (ii) harmful/dependent alcohol use only, both overall and by region and (iii) daily alcohol use. Meta-analyses examined associations between harmful alcohol use and violence, condom use, HIV/STIs, mental health problems and other drug use. In total, 435 papers were identified. After screening, 99 papers reporting on 87 unique studies with 51,904 participants from 32 LMICs met the inclusion criteria. Study designs included cross-sectional (n = 89), cohort (n = 6) and experimental (n = 4). Overall, 5 scored as high quality, 79 studies scored as moderate and 15 scored as weak quality. Twenty-nine papers reporting on 22 unique studies used validated alcohol use tools including AUDIT, CAGE and WHO CIDI. The pooled prevalence of any hazardous/harmful/dependent alcohol use was 41% (95% CI: 31-51%), and of daily alcohol use was 26% (95% CI: 17-36%). There was variation in harmful alcohol use by global region (Sub-Saharan Africa: 38%; South Asia/Central Asia/ East Asia and Pacific: 47% and Latin America and the Caribbean:44%). Harmful alcohol use was significantly associated with inconsistent condom use (pooled unadjusted RR: 1.65; 95% CI: 1.01-2.67), STIs (pooled unadjusted OR: 1.29; 95% CI 1.15-1.46); and other drug use (pooled unadjusted OR of 2.44; 95% CI 1.24-4.80), but not with HIV, violence or mental health problems. We found a high prevalence of problem alcohol use and daily alcohol use among FSWs in LMICs. Harmful drinking was associated with important HIV risk factors such as inconsistent condom use, STIs and other drug use. Major limitations included heterogeneity in tools and cut-off scores to measure alcohol use and other common risk factors, and a paucity of longitudinal studies. There is an urgent need for tailored interventions for FSWs in LMICs that address alcohol use as well as the associated sex work risk environment.

Spatial Analysis of the Alcohol, Intimate Partner Violence, and HIV Syndemic Among Women in South Africa

The co-occurrence of and synergistic interactions between substance abuse, violence, and HIV, known as the "SAVA syndemic," is thought to be a driver of women's elevated risk for HIV in sub-Saharan Africa. This study uses data from the 2016 South African Demographic and Health Survey (DHS) and the 2016 South African Census to examine geospatial associations between alcohol use, intimate partner violence (IPV), unprotected sex, and HIV status among a population-based sample of 8528 South African women (age 15-49). Results support the geographic clustering of alcohol use, unprotected sex, and IPV, but not HIV, and geospatial clustering of HIV alone. This study highlights the need for geographically-tailored interventions to address syndemics through integrated interventions, such as those simultaneously focused on alcohol, IPV, and sexual risk reduction, and points to the need for more targeted research to link these factors to HIV from a place-based risk perspective.

A savings intervention to reduce men's engagement in HIV risk behaviors: study protocol for a randomized controlled trial

BACKGROUND

In much of eastern and southern Africa, the incidence of HIV and other sexually transmitted infections (STIs) remains high despite the scale-up of promising biomedical and behavioral interventions. Studies have documented the crucial role of transactional sex-the exchange of money, material support, or goods, in sexual relationships-and heavy alcohol use in contributing to men's and women's health outcomes. Existing policy responses to this challenge have largely focused on women, through the provision of pre-exposure prophylaxis (PrEP) or structural interventions such as education subsidies and cash transfers. However, the effectiveness of these interventions has been hindered by the relative lack of interventions and programs targeting men's behavior. We describe the protocol for a study that will test an economic intervention designed to reduce men's engagement in HIV/STI-related risk behaviors in Kenya.

METHODS

We will conduct a randomized controlled trial among income-earning men in Kenya who are aged 18-39 years and self-report alcohol use and engagement in transactional sex. The study will enroll 1500 participants and randomize them to a control group or savings group. The savings group will receive access to a savings account that includes lottery-based incentives to save money regularly, opportunities to develop savings goals/strategies, and text message reminders about their savings goals. The control group will receive basic health education. Over a period of 24 months, we will collect qualitative and quantitative data from participants and a subset of their female partners. Participants will also be tested for HIV and other STIs at baseline, 12, and 24 months.

DISCUSSION

The findings from this study have the potential to address a missing element of HIV/STI prevention efforts in sub-Saharan Africa by promoting upstream and forward-looking behavior and reducing the risk of acquiring HIV/STIs in a high HIV/STI burden setting. If this study is effective, it is an innovative approach that could be scaled up and could have great potential for scientific and public health impact in Kenya.

Sexual uses of drug and alcohol among men who have sex with men in China: implications for HIV prevention

BACKGROUND

Sexual uses of alcohol and drugs are pervasive among men who have sex with men (MSM) and associated with increased risk of HIV infection. However, there are limited studies related to sexual uses of alcohol and drugs among MSM in China. This study aims to describe the pattern of alcohol use, drug use, and multi-drug use during sex among Chinese MSM and to examine the association between condomless anal intercourse, group sex, commercial sex and HIV infection.

METHODS

We conducted an online cross-sectional survey in China. Characteristics on social-demographic, sexual behaviors, and sexual uses of alcohol and drugs were collected. The associations with high-risk sexual behaviors and HIV infection were analyzed with multivariable logistic regression.

RESULTS

A total of 699 MSM were included in this study. About 39.5% (230/582) of men reported sexual alcohol use in the past three months and 50.8% (355/699) reported sexual drug use. Of those reporting sexual drug use, around 10.7% (38/355) reported having multi-drug use. Factors associated with both sexual uses of alcohol and drugs included: reporting more male sexual partners (alcohol: adjusted odds ratio [aOR] = 1.77; drug: aOR = 2.12), reporting condomless anal intercourse in the past three months (alcohol: aOR = 2.08; drug: aOR = 2.08), having ever engaged in group sex (alcohol: aOR = 2.04; drug: aOR = 5.22; multi-drug: aOR = 3.52) and commercial sex (alcohol: aOR = 4.43; drug: aOR = 4.22 multi-drug: aOR = 5.07). Sexual drug use was also correlated with reported HIV-positive status (drug: aOR = 2.53, 95% CI:1.31-4.90).

CONCLUSION

Sexual uses of alcohol and drugs are prevalent among Chinese MSM. Interventions to reduce the sexual use of alcohol and other drugs may be warranted among MSM in China.

Bar Attendance and Alcohol Use Before and After COVID-19 Related Restrictions Among HIV-infected Adults in South-Western Uganda

Alcohol use is especially problematic for people living with HIV (PLWH) and was likely to be impacted by the coronavirus disease (COVID-19) pandemic and its restrictions. In a study of PLWH with latent tuberculosis infection, we measured unhealthy alcohol use with the Alcohol Use Disorders Identification Test (AUDIT-C), phosphatidylethanol (PEth) and bar attendance. We analyzed data collected before and after COVID-19 restrictions, and used Generalized Estimating Equations (GEE) logistic regression models to evaluate changes in unhealthy alcohol use. While bar attendance declined from 57.0% before to 38.3% after the restrictions started, multivariable analysis controlling for bar use showed a significant increase in unhealthy alcohol use; the adjusted odds ratio for unhealthy drinking before versus after the restrictions started was 1.37 (95% CI: 0.89–2.12) which increased to 1.64 (95% CI: 1.08–2.50) when bar attendance was added to the model. Decline in bar attendance did not decrease unhealthy alcohol use.

Alcohol consumption and utilization of HIV prevention services among men who have casual sex with women in China

Men who have casual sex with women (MCSW) have played an important role in HIV new infections in China. Research studies have shown that heavy alcohol consumption can increase the risk of HIV infection. The cross-sectional study was conducted in two cities in China from December 2018 to May 2019 to examine the association between alcohol consumption and utilization of HIV prevention services among MCSW. Convenience sampling was used to recruit participants and 400 MCSW were recruited in this study. There were 238 (59.6%), 213 (53.4%) and 129 (32.4%) participants having utilized HIV prevention services, condom promotion and distribution or HIV counseling and testing (CPD/HCT) services, and peer education services in the past 12 months, respectively. MCSW who were identified as heavy drinkers were less likely to utilize HIV prevention services and CPD/HCT services compared with non-drinkers. For youngsters, those who are in the local household and those who are married/cohabitating, heavy drinkers was less likely to utilize HIV prevention services. This study highlights the significance of intensive education on heavy drinkers of MCSW, particularly for high-risk subgroups. Targeting resources for integrated HIV prevention efforts with alcohol-using MCSW should be considered by public health policymakers.

Demographic factors, psychiatric and physical comorbidities associated with starting preexposure prophylaxis in a nationally distributed cohort

Due to a large number of small studies and limited control for confounding, existing evidence regarding patient characteristics associated with PrEP initiation is inconsistent. We used a large electronic health record cohort to determine which demographic, physical morbidity and psychiatric conditions are associated with PrEP initiation. Eligible adult (≥18 years) patients were selected from the Optum® de-identified Electronic Health Record dataset (2010-2018). Non-HIV sexually transmitted diseases and high risk sexual behavior was used to identify patients eligible for PrEP. A fully adjusted Poisson regression model estimated the association between age, gender, race, insurance status, comorbidity index, depression, anxiety, dysthymia, severe mental illness, substance use disorder and nicotine dependence/smoking and rate of PrEP initiation. The cohort (n = 30,909) was mostly under 40 years of age (64.3%), 67.6% were female and 58.2% were White. The cumulative incidence of PrEP initiation was 1.3% (n = 408). Patients ≥60 years of age, compared to 18-29 year olds and Black compared to White patients had significantly lower rates of PrEP initiation. Anxiety disorder was significantly associated with higher rate of PrEP initiation (RR = 1.67; 95%CI:1.20-2.33) and nicotine dependence/smoking with a lower rate (RR = 0.73; 95%CI:0.54-0.97). PrEP is underutilized, and a race disparity exists in PrEP initiation. In the context of existing research, nicotine dependence/smoking is the patient characteristic most consistently associated lower rates of starting PrEP. Given the high prevalence of smoking in PrEP eligible patients, physicians may want to integrate discussions of smoking cessation in patient-provider decisions to start PrEP.

Estimating the changing burden of disease attributable to alcohol use in South Africa for 2000, 2006 and 2012

Background. Alcohol use was one of the leading contributors to South Africa (SA)’s disease burden in 2000, accounting for 7% of deaths and disability-adjusted life years (DALYs) in the first South African Comparative Risk Assessment Study (SACRA1). Since then, patterns of alcohol use have changed, as has the epidemiological evidence pertaining to the role of alcohol as a risk factor for infectious diseases, most notably HIV/AIDS and tuberculosis (TB).Objectives. To estimate the burden of disease attributable to alcohol use by sex and age group in SA in 2000, 2006 and 2012.Methods. The analysis follows the World Health Organization (WHO)’s comparative risk assessment methodology. Population attributable fractions (PAFs) were calculated from modelled exposure estimated from a systematic assessment and synthesis of 17 nationally representative surveys and relative risks based on the global review by the International Model of Alcohol Harms and Policies. PAFs were applied to the burden of disease estimates from the revised second South African National Burden of Disease Study (SANBD2) to calculate the alcohol-attributable burden for deaths and DALYs for 2000, 2006 and 2012. We quantified the uncertainty by observing the posterior distribution of the estimated prevalence of drinkers and mean use among adult drinkers (≥15 years old) in a Bayesian model. We assumed no uncertainty in the outcome measures.Results. The alcohol-attributable disease burden decreased from 2000 to 2012 after peaking in 2006, owing to shifts in the disease burden, particularly infectious disease and injuries, and changes in drinking patterns. In 2012, alcohol-attributable harm accounted for an estimated 7.1% (95% uncertainty interval (UI) 6.6 - 7.6) of all deaths and 5.6% (95% UI 5.3 - 6.0) of all DALYs. Attributable deaths were split three ways fairly evenly across major disease categories: infectious diseases (36.4%), non-communicable diseases (32.4%) and injuries (31.2%). Top rankings for alcohol-attributable DALYs for specific causes were TB (22.6%), HIV/AIDS (16.0%), road traffic injuries (15.9%), interpersonal violence (12.8%), cardiovascular disease (11.1%), cancer and cirrhosis (both 4%). Alcohol remains an important contributor to the overall disease burden, ranking fifth in terms of deaths and DALYs.Conclusion. Although reducing overall alcohol use will decrease the burden of disease at a societal level, alcohol harm reduction strategies in SA should prioritise evidence-based interventions to change drinking patterns. Frequent heavy episodic (i.e. binge) drinking accounts for the unusually large share of injuries and infectious diseases in the alcohol-attributable burden of disease profile. Interventions should focus on the distal causes of heavy drinking by focusing on strategies recommended by the WHO’s SAFER initiative.

Barriers and Facilitators to HIV Pre-Exposure Prophylaxis Uptake Among Men Who have Sex with Men Who Use Stimulants: A Qualitative Study

The HIV epidemic disproportionately impacts men who have sex with men (MSM), particularly those who use stimulants. We explored barriers and facilitators to pre-exposure prophylaxis (PrEP) uptake among this population. From June 2018 through February 2019, we conducted semi-structured interviews in Providence, Rhode Island, and New Haven, Connecticut, with 21 MSM who reported recent (past six months) stimulant use. We identified individual, interpersonal, and structural barriers to PrEP, including: (1) high awareness but mixed knowledge of PrEP, resulting in concerns about side effects and drug interactions; (2) interest that was partly determined by substance use and perceived HIV risk; (3) fragmented and constrained social networks not conducive to disseminating PrEP information; and (4) PrEP access, such as insurance coverage and cost. Our findings suggest potential approaches to increase PrEP uptake in this group, including promotion through mainstream and social media, clarifying misinformation, and facilitating increased access through structural interventions.

Features of alcohol advertisements across five urban slums in Kampala, Uganda: pilot testing a container-based approach

BACKGROUND

Despite the high prevalence of alcohol use and marketing in many settings across sub-Saharan Africa, few studies have systematically sought to assess alcohol marketing exposure, particularly in vulnerable areas such as urban slums where alcohol is often highly prevalent but where educational programs and alcohol prevention messages are scarce.

OBJECTIVE

To pilot test the development and implementation of environmental scans of alcohol advertisements in five urban slums across different areas of Kampala, Uganda: Bwaise, Kamwokya, Makindye, Nakulabye, and Nateete.

METHODS

Each of the five scans was conducted in geographical circles, within a 500-m radius of a Uganda Youth Development Link (UYDEL) drop-in Center using a container-based approach. Using a Garmin GPS with photo capabilities and a tablet for data entry, teams of at least two trained researchers walked the main roads within the target area and gathered information about each alcohol advertisement including its location, type, size, and placement and other characteristics. Data with the GPS coordinates, photos and descriptive details of the adverts were merged for analyses.

RESULTS

A total of 235 alcohol adverts were found across all five data collection sites reflecting 32 different brands. The majority of the adverts (85.8%) were smaller and medium sizes placed by restaurants and bars, stores and kiosks, and liquor stores. The most frequently noted types of alcohol in the adverts were spirits (50.6%) and beer (30.6%).

RECOMMENDATIONS

The pilot test of the methodology we developed indicated that implementation was feasible, although challenges were noted. Since monitoring alcohol marketing is key for addressing underage alcohol use and harm, the advantages and disadvantages of the approach we developed are discussed. Future research needs to strengthen and simplify strategies for monitoring alcohol marketing in low-resource settings such as urban slums which have unique features that need to be considered. Meanwhile, the findings may yield valuable information for stakeholders and to guide intervention developments and alcohol marketing policy to protect youth.

Sex in the Context of Substance Use: A Study of Perceived Benefits and Risks, Boundaries, and Behaviors among Adolescents Participating in an Internet-Based Intervention

Little research has examined adolescents' perspectives of sex with substance use. This study examined (1) adolescents' perceived benefits and risks of sex with substance use, as well as boundaries; (2) the potential for positive and negative social influences among adolescents when they discuss these topics; and (3) whether exposure to health-promoting content is associated with trajectories of sex with substance use over a 6-month period. To address the first two objectives, 176 comments were analyzed from 71 adolescents (90% female) aged 14-18 years who participated in an Internet-based sexual health promotion intervention and posted to at least one message board addressing sex with substance use. Adolescents' perceived benefits and risks of sex with substance use primarily reflected concern for the experience of sex in the moment; perceived risks and boundaries primarily reflected concern for the ability to develop and maintain meaningful relationships. Comments of 63% and 22% of adolescents, respectively, were evaluated to have potential for health-promoting and risk-promoting social influence. To address the third objective, trajectories of self-reported sex with substance use were compared between 89 intervention and 54 control participants. No significant differences were observed. However, a dose-response effect was observed; intervention participants who completed less than one third of assigned tasks reported increases in sex with alcohol or marijuana use over time, while no marked changes or much smaller changes in sex with substance use were observed among intervention participants who completed one third or more tasks. Implications for prevention and intervention programs are discussed.

Viral Suppression Levels in Men Who Have Sex With Men and Transgender Women With Newly Diagnosed HIV and Alcohol Use Disorder in Peru: Results From a Randomized, Double-Blind, Placebo-Controlled Trial Using Oral Naltrexone

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.

Correlates and Effects of Alcohol Use Expectancies Among Persons Living with HIV in Uganda

Unhealthy alcohol use fuels difficulties with HIV disease management and potentiates secondary transmission of HIV but less is known about how these alcohol use expectancies may shape alcohol use behaviors, particularly in the presence of depressive symptomatology. In this paper, we utilize data from a prospective study of 208 people living with HIV in Southwest Uganda, to examine the correlates of alcohol use expectancies and their association with unhealthy alcohol use. Affective depressive symptoms were positively associated with alcohol use expectancies. Gender moderation was observed such that depression was more strongly associated with alcohol use expectancies among women. In unadjusted analyses, alcohol use expectancies were marginally associated with unhealthy alcohol use and this association was not significant in adjusted analyses. Findings underscore the need to strengthen screening for depression and alcohol use within HIV care services, particularly among women.

Alcohol Consumption: Medical Implications, the Liver and Beyond

Alcohol consumption represents a major factor of morbidity and mortality, with a wide range of adverse medical implications that practically affect every organ system. It is the fifth major cause of deaths in men and women and causes up to 139 million disability-adjusted life years. Solid evidence places the risk as undoubtedly correlated to the length of time and amount of alcohol consumption. While alcohol-related liver disease represents one of the most studied and well-known consequences of alcohol use, the term itself embodies a wide spectrum of progressive disease stages that are responsible for almost half of the liver-related mortality worldwide. We discuss the staged alcohol-related fatty liver, alcohol-related steatohepatitis and, finally, fibrosis and cirrhosis, which ultimately may end up in a hepatocellular carcinoma. Other comorbidities such as acute and chronic pancreatitis; central nervous system; cardiovascular, respiratory and endocrine system; renal disease; urological pathologies; type 2 diabetes mellitus and even infectious diseases are reviewed in their relation to alcohol consumption. This article reviews the impact of alcohol use on different systems and organs, summarizing available evidence regarding its medical implications. It examines current basic and clinical data regarding mechanisms to highlight factors and processes that may be targetable to improve patient outcomes. Although alcohol use is a part of many cultural and social practices, as healthcare providers we must identify populations at high risk of alcohol abuse, educate patients about the potential alcohol-related harm and provide appropriate treatment.

Alcohol use and intimate partner violence in HIV-uninfected pregnant women in Cape Town, South Africa

In settings with a high burden of HIV, pregnant women often experience a cluster of risk factors, including alcohol use and intimate partner violence (IPV). These interrelated risks are poorly understood among pregnant women at risk of HIV in sub-Saharan Africa. We aim to determine cross-sectional associations between pregnant women's alcohol use and victimization due to IPV in the HIV-Unexposed-Uninfected Mother-Infant Cohort Study in Cape Town, South Africa. Women who tested HIV-negative at first antenatal care (ANC) visit were followed to delivery. Trained interviewers collected demographic and psychosocial information, including recent alcohol use and experiences of IPV victimization. We assess the prevalence of alcohol use and associations with IPV using multivariable logistic regression. In 406 HIV-uninfected pregnant women (mean age = 28 years; mean gestational age = 21 weeks), 41 (10%) reported alcohol consumption in the past 12 months; 30/41 (73%) of these at hazardous levels. Any and hazardous alcohol use were associated with greater odds of reporting past year IPV (adjusted odds ratio [aOR] for hazardous use: 3.24, 95% CI = 1.11, 7.56; aOR for any alcohol use: 2.97, 95% CI = 1.19, 7.45). These data suggest the occurrence of overlapping HIV risk factors among pregnant women and may help design improved health interventions in this population.

Sexual minority status modifies the association between HIV risk behavior and prevalent mood or anxiety disorders in British Columbia, Canada

PURPOSE

This study aimed at determining to what extent sexual minority status modifies the association between HIV risk behavior and prevalent mood or anxiety disorder diagnosis in British Columbia (BC), Canada, using a population-based survey.

METHODS

This analysis was based on the cross-sectional 2013-2014 Canadian Community Health Survey. The sample was restricted to respondents in BC with valid responses to the survey items considered. A multivariable logistic model, where the behavioral HIV risk score exposure was nested into the sexual minority status modifier, estimated the odds of having a prevalent mood or an anxiety disorder. The behavioral HIV risk score (0, 1, 2, ≥ 3) included the following five measures: (1) age at first intercourse < 14 years, (2) condom use during last intercourse, (3) history of sexually transmitted infections, (5) number of sexual partners in the past 12 months (< 4, ≥ 4), and substance use in the past 12 months.

RESULTS

Of the weighted sample (2,521,252), 97% (95% confidence interval (CI) 97-98) were heterosexual, while 3% (95% CI 2-3) were lesbian, gay, and bisexual (LGB). The prevalence of a mood or anxiety disorder diagnosis was 12% (95% CI 11-13). For every 1-level increment in the behavioral HIV risk score, the adjusted odds ratio of having a prevalent mood or anxiety disorder diagnosis was 1.29 (95% CI 1.03-1.54) for heterosexual respondents and 2.37 (95% CI 1.84-2.90) for LGB respondents.

CONCLUSION

Sexual minority status modified the relationship between HIV risk behavior and prevalent mood or anxiety disorders, with a stronger association among LGB respondents. Healthcare providers should prioritize integrated care that addresses the intersectionality between sexual risk, substance use, and mood or anxiety disorders.

The Role of Alcohol-Related Behavioral Research in the Design of HIV Secondary Prevention Interventions in the Era of Antiretroviral Therapy: Targeted Research Priorities Moving Forward

HIV secondary prevention focuses on averting onward HIV transmission, which can be realized when people living with HIV enact requisite HIV care continuum-related behaviors to achieve viral suppression, and engage in condom-protected sex when virally unsuppressed. Alcohol has been detrimentally linked to all aspects of HIV secondary prevention, and although a growing number of behavioral interventions account for and address alcohol use within this realm, further efforts are needed to fully realize the potential of such initiatives. The present article proposes a series of targeted priorities to inform the future design, implementation, and evaluation of alcohol-related behavioral intervention research within the scope of HIV secondary prevention. These priorities and corresponding approaches account for the challenges of resource-constrained clinic environments; capitalize on technology; and address key comorbidities. This framework provides the foundation for a range of alcohol-related behavioral interventions that could potentially enhance global HIV secondary prevention efforts in the years ahead.

Drugs of Abuse and Their Impact on Viral Pathogenesis

Commonly misused substances such as alcohol, cocaine, heroin, methamphetamine, and opioids suppress immune responses and may impact viral pathogenesis. In recent years, illicit use of opioids has fueled outbreaks of several viral pathogens, including the human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). This review focuses on the myriad of mechanisms by which drugs of abuse impact viral replication and disease progression. Virus–drug interactions can accelerate viral disease progression and lead to increased risk of virus transmission.

The limits of measuring binge drinking prevalence for epidemiological surveillance: An example from Spain

BACKGROUND

The public health impact of binge drinking depends on its population prevalence and its frequency and intensity among binge drinkers. The objective is to assess the consistency of time trends and age-sex disparities between binge-drinking prevalence and binge-drinking exposure indicators that combine such prevalence with the number of binge-drinking days among binge drinkers.

METHODS

Data come from 11 biennial national household surveys from 1997 to 2017 in young (15-34 years) and middle-aged adults (35-64 years) in Spain (n = 211,961). Binge-drinking was the intake of 5+ standard drinks (4+ in women from 2009 onwards) in approximately two hours. Three monthly indicators were analyzed: binge-drinking prevalence, population rate of binge-drinking days, and proportion of drinking days with binge drinking. Results were stratified for sex and two age groups. Annual percent changes (APCs), ratios of young to middle-aged people (age ratios) and men-to-women ratios were obtained from negative binomial regression.

RESULTS

Although the three indicators showed considerable consistency as an intense increase in binge drinking from 2009 to 2017 among middle-aged people, especially women, there were relevant inconsistencies. In 2009-2017 the APCs for prevalence and rate were +1.3 % and -1.6 %, respectively, in young women, and -0.6 % and -3.0 % in young men. Age ratios were significantly higher for prevalence and proportional ratio than rates, while men-to-women ratios were lower, especially in middle-aged people.

CONCLUSIONS

Adequate monitoring of binge drinking should incorporate indicators of absolute exposure, which better reflect its impact on public health, such as the population rate of binge-drinking days.

Alcohol Use and the Risk of Communicable Diseases

The body of knowledge on alcohol use and communicable diseases has been growing in recent years. Using a narrative review approach, this paper discusses alcohol's role in the acquisition of and treatment outcomes from four different communicable diseases: these include three conditions included in comparative risk assessments to date-Human Immunodeficiency Virus (HIV)/AIDS, tuberculosis (TB), and lower respiratory infections/pneumonia-as well as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) because of its recent and rapid ascension as a global health concern. Alcohol-attributable TB, HIV, and pneumonia combined were responsible for approximately 360,000 deaths and 13 million disability-adjusted life years lost (DALYs) in 2016, with alcohol-attributable TB deaths and DALYs predominating. There is strong evidence that alcohol is associated with increased incidence of and poorer treatment outcomes from HIV, TB, and pneumonia, via both behavioral and biological mechanisms. Preliminary studies suggest that heavy drinkers and those with alcohol use disorders are at increased risk of COVID-19 infection and severe illness. Aside from HIV research, limited research exists that can guide interventions for addressing alcohol-attributable TB and pneumonia or COVID-19. Implementation of effective individual-level interventions and alcohol control policies as a means of reducing the burden of communicable diseases is recommended.

The Impact of Closeness to Non-Parental Adults in Social Networks on Substance Use among Young Men Who Have Sex with Men

Non-parental adults (NPAs), or adults in social networks other than parents and romantic/sexual partnersare an under-examined potential resource in the lives of young men who have sex with men (YMSM). Using survey and social network data from a sample (n = 169) of ethnically diverse YMSM in a Midwestern city, this article examines longitudinal associations between emotional closeness to NPAs and subsequent substance use among YMSM. After controlling for race/ethnicity, closer relationships with NPAs were associated with a lower likelihood of binge-drinking and marijuana use six months later. In an exploratory set of analyses, the level of connectedness between NPAs and other members of social networks was not associated with substance use. Future studies should continue to examine the protective role of NPAs for both substance use and other health behaviors among YMSM.

Leisure Boredom, Timing of Sexual Debut, and Co-Occurring Behaviors among South African Adolescents

Sex during adolescence is normative; however, there are substantial individual differences in the timing and context of sexual debut. Leisure boredom is an underexplored correlate of sexual behavior that is associated with many adolescent health outcomes. We investigated if and how individual differences in leisure boredom may be associated with timing of sexual debut, and whether individuals engage in safe or risky behaviors at debut. Survival analysis, logistic regression, and Poisson regression were applied to eight-wave longitudinal data obtained from 3,088 South African adolescents (baseline M_age = 13.9 years) to examine associations between leisure boredom and cumulative hazard of sexual debut across adolescence, odds of co-occurring sexual behaviors, and incidence rate of co-occurring sexual risk behaviors at debut. Higher levels of leisure boredom were associated with elevated hazard cumulatively across adolescence. Higher levels of leisure boredom were also associated with lower odds of safe sex and higher odds of substance use during sex and transactional sex at sexual debut, but not casual sex or condom non-use at sexual debut. Although odds of singular risk behaviors were lower for girls than for boys, the association between leisure boredom and the number of risk behaviors at sexual debut was stronger for girls than boys. Higher trait leisure boredom was associated with elevated hazard of sexual debut, greater likelihood that risky behaviors accompanied sexual debut, and greater number of co-occurring risky behaviors at sexual debut. Results support leisure boredom as a potential target for preventing sexual risk behavior among South African adolescents.

Addressing Unhealthy Alcohol Use and the HIV Pre-exposure Prophylaxis Care Continuum in Primary Care: A Scoping Review

Individuals with unhealthy alcohol use are at increased risk for HIV acquisition and may benefit from receiving HIV pre-exposure prophylaxis (PrEP) in primary care settings. To date, literature synthesizing what is known about the impact of unhealthy alcohol use on the PrEP care continuum with a focus on considerations for primary care is lacking. We searched OVID Medline and Web of Science from inception through March 19, 2020, to examine the extent, range, and nature of research on PrEP delivery among individuals with unhealthy alcohol use in primary care settings. We identified barriers and opportunities at each step along the PrEP care continuum, including for specific populations: adolescents, people who inject drugs, sex workers, and transgender persons. Future research should focus on identification of candidate patients, opportunities for patient engagement in novel settings, PrEP implementation strategies, and stigma reduction.

Testing the Effect of Social Norms Theory-based Interventions: Are they Harmful for University Students who Drink Less than the Peer Norm?

Background. Social norms theory-based interventions have been widely used to reduce alcohol consumption among college and university students. Lately, it has been argued that such interventions may actually increase alcohol use among light drinkers. However, little studies have been focused on testing this possible negative effect. Objectives. The aim of this study was to examine possible negative impact of descriptive normative feedback (DNF) on drinking intentions among students whose baseline drinking scores were below the average of a reference group. We also studied the preventive effect of injunctive normative feedback (INF). Methods. Actual descriptive and injunctive norms were collected from 234 university students. From those who reported drinking below the norm, 26 were randomly assigned to a control or intervention condition that received normative feedback via PowerPoint presentations over two meetings. Results. DNF increased students’ intentions of spirits drinking frequency and quantity. Meanwhile intentions to drink beer, cider, wine and cocktails remained the same. Increased intentions to drink spirits were not reduced by INF. Conclusions. Findings suggest that DNF-based interventions might negatively affect the use of spirits among those students who consume less than their peer norm by increasing their intentions to drink spirits more often and in larger quantities. Ways other than the INF to prevent this negative effect need to be further explored.

Assessing Intertemporal Socioeconomic Inequalities in Alcohol Consumption in South Africa

Background: This paper assesses changes in the socioeconomic inequality in alcohol consumption by exploring whether alcohol consumption (current and binge drinkers) is more prevalent among the wealthier (pro-rich) or poorer (pro-poor) group over time.

Methods: Data come from the 2008, 2010/11, 2012, and 2014/15 waves of the National Income Dynamics Study (NIDS). Various equity stratifiers (sex, age, race, and rural/urban) are used to analyze the prevalence of alcohol consumption and to investigate differences in socioeconomic inequalities. Changes in socioeconomic inequality in alcohol consumption between 2008 and 2014/15 were also assessed using the concentration index.

Results: Current drinkers were more concentrated among richer South Africans, while binge drinkers were concentrated among the poorer population. For current drinkers, irrespective of sex, race, age, and urban, socioeconomic inequality in alcohol consumption had become less pro-rich between 2008 and 2014/15; while inequality in binge drinking, outside of the Asian/Indian and rural categories, had become less pro-poor between 2008 and 2014/15.

Conclusion: The results show evidence that binge drinking is a bigger problem among those of low-SES, young individuals, male and African populations. This paper concludes that the SA government should continue to push forward policies aiming to reduce the prevalence of binge drinking.

Horizons and Group Motivational Enhancement Therapy: HIV Prevention for Alcohol-Using Young Black Women, a Randomized Experiment

INTRODUCTION

Black women are at disproportionately greater risk for HIV and sexually transmitted infections than women of other ethnic/racial backgrounds. Alcohol use may further elevate the risk of HIV/sexually transmitted infection acquisition and transmission.

STUDY DESIGN

A random-assignment parallel-group comparative treatment efficacy trial was conducted with random assignment to 1 of 3 conditions.

SETTING/PARTICIPANTS

The sample comprised 560 Black or African American women aged 18-24 years who reported recent unprotected vaginal or anal sex and recent alcohol use. Participants were recruited from community settings in Atlanta, Georgia, from January 2012 to February 2014.

INTERVENTION

A Group Motivational Enhancement Therapy module was designed to complement a Centers for Disease Control and Prevention-designated evidence-based intervention (Horizons) to reduce sexual risk behaviors, alcohol use, and sexually transmitted infections, with 3 comparison groups: (1) Horizons + Group Motivational Enhancement Therapy intervention, (2) Horizons + General Health Promotion intervention, and (3) enhanced standard of care.

MAIN OUTCOME MEASURES

Outcome measures included safe sex (abstinence or 100% condom use); condom nonuse; proportion of condom use during sexual episodes; incident chlamydia, gonorrhea, and trichomonas infections; and problematic alcohol use measured by Alcohol Use Disorders Identification Test score. Treatment effects were estimated using an intention-to-treat protocol‒generalized estimating equations with logistic regression for binomial outcomes and Poisson regression for count outcomes. Analyses were conducted between October 2018 and October 2019.

RESULTS

Participants assigned to Horizons + Group Motivational Enhancement Therapy had greater odds of safe sex (AOR=1.45, 95% CI=1.04, 2.02, p=0.03), greater proportion of condom use (AOR=1.68, 95% CI=1.18, 2.41, p=0.004), and lower odds of condom nonuse (AOR=0.57, 95% CI=0.38, 0.83, p=0.004). Both interventions had lower odds of problematic alcohol use (Horizons: AOR=0.57, 95% CI=0.39, 0.85, p=0.006; Horizons + Group Motivational Enhancement Therapy: AOR=0.61, 95% CI=0.41, 0.90, p=0.01).

CONCLUSIONS

Complementing an evidence-based HIV prevention intervention with Group Motivational Enhancement Therapy may increase safer sexual behaviors and concomitantly reduce alcohol use among young Black women who consume alcohol.

Advancing a cascading train-the-trainer model of frontline HIV service providers in South Africa: protocol of an implementation trial

BACKGROUND

South Africa is marked by high rates of both HIV and alcohol use, and there is a detrimental synergistic relationship between these two epidemics. The Institute of Medicine recommends integrated care for alcohol use treatment and HIV, but implementation of integrated services remains a challenge in South Africa. This protocol describes a study designed to evaluate trainer, provider-, and patient encounter-level outcomes relating to the national rollout of a cascade train-the-trainer model of task-sharing to build capacity of the HIV workforce to deliver Screening, Brief Intervention, and Referral to Treatment (SBIRT) to address risky alcohol use.

METHODS

This 5 year protocol consists of two phases. First, we will finalize development of a robust SBIRT train-the-trainer model, which will include an SBIRT Trainer Manual, Provider Resource Guide, fidelity observational coding system, case vignettes, and a curriculum for ongoing consultation sessions. Materials will be designed to build the capacity of novice trainers to train lay workers to deliver SBIRT with fidelity. Second, we will recruit 24-36 trainers and 900 providers in order to evaluate the effects of the SBIRT train-the-trainer model on trainer- (e.g., fidelity, knowledge), provider- (e.g., SBIRT attitudes, confidence, acceptability), and patient encounter- (e.g., proportion receiving screening, brief intervention, referral to treatment) level variables. Data on patient encounters will be tracked by providers on programmed tablets or scannable paper forms in real-time. Providers will report on SBIRT delivery on an ongoing basis over a 6-months period. Additionally, we will test the hypothesis that trainer-level factors will account for a substantial proportion of variability in provider-level factors which will, in turn, account for a substantial proportion of variability in patient encounter-level outcomes.

DISCUSSION

This protocol will allow us to take advantage of a unique national training initiative to gather comprehensive data on multi-level factors associated with the implementation of SBIRT in HIV service settings. In the long-term, this research can help to advance the implementation of integrated alcohol-HIV services, providing lessons that can extend to other low-and-middle income countries confronting dual epidemics.

Educational attainment impacts drinking behaviors and risk for alcohol dependence: results from a two-sample Mendelian randomization study with ~780,000 participants

Observational studies suggest that lower educational attainment (EA) may be associated with risky alcohol use behaviors; however, these findings may be biased by confounding and reverse causality. We performed two-sample Mendelian randomization (MR) using summary statistics from recent genome-wide association studies (GWAS) with >780,000 participants to assess the causal effects of EA on alcohol use behaviors and alcohol dependence (AD). Fifty-three independent genome-wide significant SNPs previously associated with EA were tested for association with alcohol use behaviors. We show that while genetic instruments associated with increased EA are not associated with total amount of weekly drinks, they are associated with reduced frequency of binge drinking ≥6 drinks (ß_IVW = -0.198, 95% CI, -0.297 to -0.099, P_IVW = 9.14 × 10^-5), reduced total drinks consumed per drinking day (ß_IVW = -0.207, 95% CI, -0.293 to -0.120, P_IVW = 2.87 × 10^-6), as well as lower weekly distilled spirits intake (ß_IVW = -0.148, 95% CI, -0.188 to -0.107, P_IVW = 6.24 × 10^-13). Conversely, genetic instruments for increased EA were associated with increased alcohol intake frequency (ß_IVW = 0.331, 95% CI, 0.267-0.396, P_IVW = 4.62 × 10^-24), and increased weekly white wine (ß_IVW = 0.199, 95% CI, 0.159-0.238, P_IVW = 7.96 × 10^-23) and red wine intake (ß_IVW = 0.204, 95% CI, 0.161-0.248, P_IVW = 6.67 × 10^-20). Genetic instruments associated with increased EA reduced AD risk: an additional 3.61 years schooling reduced the risk by ~50% (OR_IVW = 0.508, 95% CI, 0.315-0.819, P_IVW = 5.52 × 10^-3). Consistency of results across complementary MR methods accommodating different assumptions about genetic pleiotropy strengthened causal inference. Our findings suggest EA may have important effects on alcohol consumption patterns and may provide potential mechanisms explaining reported associations between EA and adverse health outcomes.

Quantifying alcohol use among Ecuadorian human immunodeficiency virus positive individuals and assessing alcohol as an independent risk factor for human immunodeficiency virus: A case control study STROBE

Alcohol abuse has been identified as a risk factor for contracting human immunodeficiency virus (HIV) and accelerating disease progression. Our study aims to determine alcohol consumption rates among Ecuadorian HIV positive (HIV+) patients prior to diagnosis to evaluate its impact as an independent risk factor for contracting HIV. Additionally, we will examine post-diagnosis consumption rates among the HIV+ population.We provided anonymous questionnaires to 300 HIV+ patients and 600 internal medicine patients at 3 hospitals in Quito, Ecuador. Questionnaires quantified alcohol usage prior to HIV diagnosis, at time of diagnosis, and post-diagnosis while accounting for other potential HIV risk factors. We then determined frequencies of alcohol consumption and confounding variables. Finally, we performed a multivariable logistic regression controlling for confounders to determine the statistical significance of alcohol consumption as an independent risk factor for HIV.Our results showed increased odds for contracting HIV among those who drank daily (OR 5.3, CI 2.0-14.0) and those who consumed 6 or more alcoholic beverages on days they drank (OR 5.0, CI 3.1-8.2). Through multivariable analysis, we found that abstaining from binge drinking was a protective factor with an OR 0.5 (0.3-0.96). The percentage of HIV+ patients abstaining from alcohol increased from 30% twelve months prior to diagnosis to 57% after diagnosis.Our results show that alcohol abuse significantly increases the risk of contracting HIV. We found that prior to diagnosis, HIV patients consistently drank more frequently and a greater amount than the control group. Alcohol use significantly decreased among HIV+ patients after diagnosis.

Lower rates of ART initiation and decreased retention among ART-naïve patients who consume alcohol enrolling in HIV care and treatment programs in Kenya and Uganda

Objectives

Almost 13 million people are estimated to be on antiretroviral therapy in Eastern and Southern Africa, and their disease course and program effectiveness could be significantly affected by the concurrent use of alcohol. Screening for alcohol use may be important to assess the prevalence of alcohol consumption and its impact on patient and programmatic outcomes.

Methods

As part of this observational study, data on patient characteristics and alcohol consumption were collected on a cohort of 765 adult patients enrolling in HIV care in East Africa. Alcohol consumption was assessed with the AUDIT questionnaire at enrollment. Subjects were classified as consuming any alcohol (AUDIT score >0), hazardous drinkers (AUDIT score ≥8) and hyper drinkers (AUDIT score ≥16). The effects of alcohol consumption on retention in care, death and delays in antiretroviral therapy (ART) initiation were assessed through competing risk (Fine & Gray) models.

Results

Of all study participants, 41.6% consumed alcohol, 26.7% were classified as hazardous drinkers, and 16.0% as hyper drinkers. Depending on alcohol consumption classification, men were 3–4 times more likely to consume alcohol compared to women. Hazardous drinkers (median age 32.8 years) and hyper drinkers (32.7 years) were slightly older compared to non-hazardous drinkers (30.7 years) and non-hyper drinkers (30.8 years), (p-values = 0.014 and 0.053 respectively). Median CD4 at enrollment was 330 cells/μl and 16% were classified World Health Organization (WHO) stage 3 or 4. There was no association between alcohol consumption and CD4 count or WHO stage at enrollment. Alcohol consumption was associated with significantly lower probability of ART initiation (adjusted sub-distribution hazard ratio aSHR = 0.77 between alcohol consumers versus non-consumers; p-value = 0.008), and higher patient non-retention in care (aSHR = 1.77, p-value = 0.023).

Discussion

Alcohol consumption is associated with significant delays in ART initiation and reduced retention in care for patients enrolling in HIV care and treatment programs in East Africa. Consequently, interventions that target alcohol consumption may have a significant impact on the HIV care cascade.

HIV-Related Mistrust (or HIV Conspiracy Theories) and Willingness to Use PrEP Among Black Women in the United States

Uptake of pre-exposure prophylaxis (PrEP) among Black women living in the US is suboptimal. We sought to determine the association between HIV-related medical mistrust (or belief in HIV conspiracy theories) and willingness to use PrEP among Black women. We analyzed data from the 2016 National Survey on HIV in the Black Community (NSHBC), a nationally representative cross-sectional survey. Among NSHBC participants, 522 were women and 347 (69.0%) reported HIV risk factors. Only 14.1% were aware that PrEP exists; 30.8% reported willingness to use PrEP. HIV-related medical mistrust was reported by 60.4% of women. In multivariable analysis, controlling for income, education, marital status and health care engagement, belief in conspiracy theories was significantly associated with higher willingness to use PrEP. The HIV-Related Medical Mistrust Scale item: "there is a cure for HIV, but the government is withholding it from the poor" was independently associated with higher PrEP willingness. This finding speaks to the need for an improved understanding of the role of HIV-related medical mistrust among Black women to improve uptake of biomedical HIV prevention.

Correlates of alcohol use disorder pharmacotherapy receipt in medically insured patients

BACKGROUND

Alcohol use disorder is a highly prevalent disease with multiple medications available for treatment. The overall prevalence of patients receiving pharmacotherapy is believed to be low and the characteristics and comorbidities that affect receipt are not well-established.

METHODS

We created a dataset from Truven Health Analytics MarketScan Commercial Claims and Encounters Database of patients with an outpatient encounter for alcohol abuse or dependence in 2014. We subsequently identified patient characteristics, comorbid medical, psychiatric, or substance use disorders, as well as encounter provider specialties and, using multivariable logistic regression, assessed which variables correlated with increased or decreased receipt of pharmacotherapy for alcohol use disorder for this population.

RESULTS

In our dataset of 123,355 patients, patient receipt of pharmacotherapy for alcohol use disorder was 3.3 %, and 9.3 % when restricted to the former diagnosis of alcohol dependence only. Male sex, younger age, alcohol-related liver disease, and cannabis use disorders correlated with decreased receipt whereas comorbid major depressive disorders and anxiety disorders correlated with increased receipt. Compared to patients seen by psychiatrists, those seen by primary medical doctors had a lower odds of receiving pharmacotherapy.

CONCLUSIONS

Pharmacotherapy for alcohol use disorder is an underutilized treatment modality with a low prevalence of prescription in insured individuals. Patients with specific characteristics and comorbidities are less likely to receive this treatment and greater focus on these patients and in the primary care setting can allow for increased prescribing of these medications.

The incidence of HIV and associated risk factors among pregnant women in Kabarole District, Uganda

OBJECTIVES

The study attempted to determine the incidence of HIV among pregnant women in Kabarole District, Uganda, and to identify socio-demographic and behavioral risk factors for seroconversion during pregnancy.

METHODS

We carried out a retrospective cohort study among women for whom a documented HIV-negative test result from the first pregnancy trimester could be confirmed using available records, and who were HIV-retested in the third trimester or during delivery. In total, 1610 pregnant women from three different healthcare settings took part in the study. We captured the results of repeated HIV tests and conducted semi-structured interviews to explore participants' socio-demographic characteristics and sexual risk behavior. For HIV incidence rates, we calculated the number of seroconversions per 100 person-years. We used Fisher's exact test to test for potential associations. Penalized maximum likelihood logistic regression and Poisson regression were applied to adjust for potential confounders.

RESULTS

The overall HIV incidence rate among participants was 2.9/100 women-years. Among socio-demographic characteristics, the multivariable analysis showed a significant association of marital status with HIV incidence in pregnancy (IRR 8.78, 95%CI [1.13-68.33]). Risky sexual behaviors including higher number of sexual partners in pregnancy (IRR 2.78 [1.30-5.94]), unprotected sex with unknown persons (IRR 14.25 [4.52-44.93]), alcohol abuse (IRR 12.08 [4.18-34.90]) and sex under the influence of drugs or alcohol (IRR 6.33 [1.36-29.49]) were significantly associated with seroconversion in pregnancy (similar results in logistic regression).

CONCLUSIONS

HIV incidence was three times higher among our pregnant study population compared to the general female population in Uganda. This underlines the importance of HIV prevention and repeat testing during pregnancy. Identified risk groups should be considered for pre-exposure prophylaxis.

Characteristics of Sex Events, Partners, and Motivations and Their Associations with HIV-Risk Behavior in a Daily Diary Study of High-Risk Men Who Have Sex with Men (MSM)

In the United States, men who have sex with men (MSM) continue to be at high-risk for HIV and other STIs, and condoms represent the most popular, affordable, and accessible method of prevention. Although a vast body of research has explored various factors associated with condom use in MSM, fewer studies have explored situation-level characteristics that affect their decisions about sex partners and condom use. Daily diary studies are well-suited to help improve our understanding of these event-level factors in detail, including the sex events themselves, partner characteristics, and motivations. As part of a larger study using ecological momentary assessment methods, high-risk MSM completed daily diary surveys about their sexual behavior on their smartphones each day for 30 days. This study explored detailed descriptive characteristics of sex events, partner characteristics, and motivations for sex and condom use, and examined whether specific aspects of these characteristics were associated with having condomless anal sex (CAS) with high-risk partners. High-risk CAS was common among MSM, with the majority of participants having met their partners online and many reporting sex the same day they met. Results showed that the odds of CAS were not higher with partners met online versus those met in other ways, but MSM were more likely to have asked online partners about their HIV status and testing history before sex. The odds of engaging in high-risk CAS was higher when MSM reported intimacy or self-assurance motives. Not having condoms readily available was a CAS motivation reported more commonly when MSM had sex with high-risk partners. Findings suggest that interventions should incorporate strategies that help MSM be safer specifically when meeting partners online and when having sex for intimacy or re-assurance. Interventions that remind MSM to carry condoms at opportune moments may also help reduce some HIV risk.

The Unaddressed Needs of Alcohol-Using Couples on Antiretroviral Therapy in Malawi: Formative Research on Multilevel Interventions

Alcohol use among HIV-positive individuals in sub-Saharan Africa directly impacts adherence to antiretroviral therapy and HIV outcomes. Few studies have examined approaches to reduce alcohol use among HIV-affected couples, despite evidence that alcohol use is a couple-level concern. We conducted a qualitative study with 23 alcohol-using couples to identify multilevel barriers and facilitators of alcohol use, and potential intervention options with couples. Data were analyzed at individual and dyadic levels using framework analysis. All couples were married and had at least one partner on ART. Men were the primary alcohol drinkers with few women reporting alcohol use. Most women tried to persuade their partners to reduce their alcohol intake and when unsuccessful, enlisted help from relatives and HIV care providers. Effective couple negotiation around men's alcohol use was constrained by negative peer influence and men's desire for friendship to cope with life stressors. Women were primarily concerned about the expense of alcohol and described how alcohol prevented the family from meeting basic needs and investing in the future. Alcohol use was described as a major barrier to ART adherence, but was also viewed as the cause of couple and family violence, extramarital partnerships, food insecurity, and poverty. We conclude that multilevel interventions based on couples' needs and preferences are urgently needed. Couple-based intervention approaches could include provider-led alcohol counseling with couples, alcohol reduction support groups for couples, couples' counseling to bolster couple communication and problem-solving around alcohol, and economic-strengthening interventions for couples.

Attributes of HIV infection over decades (1982-2018): A systematic review and meta-analysis

Understanding the risk factors for HIV infection is the foundation of successful preventive strategies, which must bundle sociocultural, behavioural and biomedical interventions to halt disease transmission. We aimed in this study to provide a pooled estimation of HIV risk factors and trace changes across decades in order to drive consensus and accurate assessment of disease transmission risk. We comprehensively searched PubMed, ISI Web of Knowledge, Medline, EMBASE, ScienceDirect, Ovid, EBSCO, Google Scholar and the Egyptian Universities Library Consortium from October to December 2018. Two independent reviewers extracted data from eligible studies. Funnel plots were inspected to identify publication bias. Heterogeneity across studies was checked using the Q and I² statistics. The results were reported based on the pooled odds ratio (pOR) with 95% CI using a random-effects model. Meta-analysis of HIV risk factors revealed a superior role for risky sexual practices (unprotected vaginal/anal sex), injecting drug use (IDU), sharing needles, sexually transmitted infections (STIs), child sexual abuse and vertical transmissions. Trends across decades (1982-1999 and 2000-2018, respectively) showed rising evidence for prostitution [pOR (95% CI)= 2.3 (1.12-4.68) versus 2.69 (1.67-4.32)] and men who have sex with men (MSM) [pOR (95% CI)= 2.28 (1.64-3.17) versus 3.67 (1.88-7.17)], while transmission through IDU [pOR (95% CI)= 3.42 (2.28-5.12) versus 2.16 (1.74-2.70)], alcoholism [pOR (95% CI)= 2.35 (0.73-7.59) versus 1.71(1.08-2.72)], and sharing syringes [pOR (95% CI)= 6.10 (2.57-14.5) versus 2.70 (2.01-6.35)] showed notable decline. Harm reduction programs and condom use have been recognized as chief HIV prevention strategies, while male circumcision contributed a partial role. Collectively, sexual risk factors continue to be a key driver of the global HIV epidemic. Persistent and emerging risk factors identified in our analysis should constitute the forefront targets of HIV prevention programmes to accelerate efforts towards HIV elimination.

Alcohol dependence and physical comorbidity: Increased prevalence but reduced relevance of individual comorbidities for hospital-based mortality during a 12.5-year observation period in general hospital admissions in urban North-West England

Purpose:

Alcohol dependence (AD) is associated with an increase in physical comorbidities. The effects of these diseases on general hospital-based mortality are unclear. Consequently, we conducted a mortality study in which we investigated if the burden of physical comorbidities and their relevance on general hospital-based mortality differs between individuals with and without AD during a 12.5-year observation period in general hospital admissions.

Methods:

During 1 January 2000 and 30 June 2012, 23,371 individuals with AD were admitted at least once to seven General Manchester Hospitals. Their physical comorbidities with a prevalence ≥ 1% were compared to those of 233,710 randomly selected hospital controls, group-matched for age and gender (regardless of primary admission diagnosis or specialized treatments). Physical comorbidities that increased the risk of hospital-based mortality (but not outside of the hospital) during the observation period were identified using multiple logistic regression analyses.

Results:

Hospital-based mortality rates were 20.4% in the AD sample and 8.3% in the control sample. Individuals with AD compared to controls had a higher burden of physical comorbidities, i.e. alcoholic liver and pancreatic diseases, diseases of the conducting airways, neurological and circulatory diseases, diseases of the upper gastrointestinal tract, renal diseases, cellulitis, iron deficiency anemia, fracture neck of femur, and peripheral vascular disease. In contrast, coronary heart related diseases, risk factors of cardiovascular disease, diverticular disease and cataracts were less frequent in individuals with AD than in controls. Thirty-two individual physical comorbidities contributed to the prediction of hospital-based mortality in univariate analyses in the AD sample; alcoholic liver disease (33.7%), hypertension (16.9%), chronic obstructive pulmonary disease (14.1%), and pneumonia (13.3%) were the most frequent diagnoses in deceased individuals with AD. Multiple forward logistic regression analysis, accounting for possible associations of diseases, identified twenty-three physical comorbidities contributing to hospital-based mortality in individuals with AD. However, all these comorbidities had an equal or even lower impact on hospital-based mortality than in the comparison sample.

Conclusion:

The excess of in-hospital deaths in general hospitals in individuals with AD is due to an increase of multiple physical comorbidities, even though individual diseases have an equal or even reduced impact on general hospital-based mortality in individuals with AD compared to controls.

Characterizing Men Who Have Sex with Transgender Women in Lima, Peru: Sexual Behavior and Partnership Profiles

HIV prevalence is high among transgender women (TW), but how HIV is transmitted to this population is not well understood. This analysis aims to characterize sexual partners of TW (PTW) to understand how their behavior contributes to HIV risk among TW. We examined baseline data from TW, PTW, and men who have sex with men (MSM) from a treatment-as-prevention study in Lima, Peru. Individual and partnership characteristics were compared across groups, and Poisson regression was used to calculate prevalence ratios for associations between sexual concurrency and potential correlates. We found that 81% of PTW had no cisgender male partners. Prevalence of alcohol dependency, concurrency, and condomless anal intercourse was high and HIV testing was low compared to the other groups. Our results suggest that PTW are a distinct population from MSM and TW, engage in behavior associated with HIV transmission, and are likely not well reached by HIV prevention interventions.

Brief Report: Comparing Sexual Risk Behavior in a High-Risk Group of Men Who Have Sex With Men and Transgender Women in Lima, Peru

BACKGROUND

Transgender women (TW) and men who have sex with men (MSM) are often conflated in HIV research and prevention programs, despite clear differences that exist in culture and behavior.

METHODS

We examined baseline data from a large treatment-as-prevention study among TW and MSM in Lima, Peru, to assess differences in risk behavior. Baseline assessment included HIV testing and a questionnaire including sociodemographics, sexual behavior, social venue attendance, and drug and alcohol use. Poisson regression with robust standard errors was used to calculate prevalence ratios adjusted for confounding variables [adjusted prevalence ratio (aPR)] and 95% confidence intervals (CIs) comparing the prevalence of covariates related to HIV risk in MSM and TW.

RESULTS

Overall, 310 TW and 2807 MSM participated between July 2013 and September 2015 and were included in this analysis. TW engaged in some protective sexual health practices more than MSM, including HIV testing in the last year (aPR = 1.62; 95% CI: 1.42 to 1.84) and condom use at the last sexual encounter (aPR = 1.20; 95% CI: 1.06 to 1.36). TW were more likely to have sex while using alcohol (aPR 1.15, 95% CI: 1.01 to 1.31) or drugs (aPR 2.24, 95% CI: 1.47 to 3.41), have alcohol dependency (aPR 1.38, 95% CI: 1.15 to 1.66), engage in receptive anal sex (aPR 1.31, 95% CI: 1.26 to 1.36), and have received money, gifts, or favors in exchange of anal sex (1.96, 95% CI: 1.74 to 2.20).

CONCLUSIONS

TW and MSM exhibited distinct risk profiles, suggesting that interventions specifically targeted to each group may provide new opportunities for more effective HIV prevention programs.

Alcohol use and sexual risk behaviors in the Armed Forces of the Democratic Republic of the Congo

Background

Alcohol misuse is an important contributor to sexual acquisition and transmission of HIV in military communities. This cross-sectional study quantified the prevalence of probable problematic alcohol use among male service members in the Armed Forces of the Democratic Republic of the Congo (FARDC), identified associated factors, and investigated associations of alcohol misuse with risky sexual behaviors.

Methods

Participants included 2549 active duty male soldiers ≥ 18 years old. Data were collected via computer-assisted personal-interview from October 2013–April 2014. The Alcohol Use Disorders Identification Test (AUDIT) was used to identify probable problematic alcohol use (AUDIT score ≥ 8) compared to no/low-risk alcohol use (AUDIT score ≤ 7). Bivariate logistic regressions were used to identify factors associated with probable problematic alcohol use. Several multivariable logistic regressions (adjusted for age, marital status, education level) were used to examine associations of probable problematic alcohol use with risky sexual behaviors. Tests were two sided; statistical significance was defined as p < 0.05.

Results

Fifteen percent of men screened positive for probable problematic alcohol use. The odds of probable problematic alcohol use were elevated among men who were single and living with a partner (OR = 1.66; 95% CI = 1.24–2.21), ranked as a non-commissioned officer [NCO] (OR = 1.40; 95% CI = 1.10–1.77), and in the 30–39 and 40–49 age groups (OR 30–39 age group = 2.17; 95% CI = 1.56–3.02; OR 40–49 age group = 1.79; 95% CI = 1.26–2.55). Probable problematic alcohol use was associated with increased odds of having sex with a sex worker (SW), having multiple sexual partners, and participating in transactional sex (aOR sex with a SW = 2.36; 95% CI = 1.78–3.13; aOR multiple sexual partners = 2.08; 95% CI = 1.66–2.60; aOR transactional sex = 1.99; 95% CI = 1.59–2.50).

Conclusions

Results emphasize the need to address alcohol use in the FARDC and integrate alcohol abuse education into HIV prevention programs among male service members. Alcohol abuse prevention efforts should target men who are 30–49 years of age, unmarried, and ranked as a NCO. Messages and interventions to reduce alcohol misuse in relation to risky sexual behaviors are needed.
