RESUMEN

BACKGROUND: Many people living with HIV (PLWH) use cannabis for medicinal reasons. Patients' knowledge of the tetrahydrocannabinol (THC) and cannabidiol (CBD) concentrations of the cannabis products they use may be important in helping patients achieve symptom relief while guarding against potential risks of cannabis use. However, no studies have examined cannabinoid concentration knowledge among PLWH. METHOD: PLWH (N = 29; 76% men, mean age 47 years) reporting cannabis use for both medicinal and nonmedicinal reasons completed daily surveys over 14 days assessing cannabis products used, knowledge of cannabinoid concentrations of cannabis products used, cannabis use motives (medicinal, nonmedicinal, both), and positive and negative cannabis-related consequences. Across the 361 cannabis use days captured on the daily surveys, at least some knowledge of cannabinoid concentrations was reported on an average of 43.1% (for THC) and 26.6% (for CBD) of the days. RESULTS: Generalized linear mixed models revealed that participants were more likely to report knowing THC and CBD concentrations on days when they used non-flower forms of cannabis relative to days when they used cannabis flower only. Participants who used cannabis for medicinal reasons on a greater proportion of days had greater knowledge of cannabinoid concentration overall across days. Further, greater overall knowledge of cannabinoid concentrations was associated with fewer reported negative cannabis-related consequences. CONCLUSIONS: Findings suggest that among PLWH, knowledge of cannabinoid concentrations may be higher when using non-flower cannabis products and among those reporting primarily medicinal cannabis use. Moreover, knowledge of cannabinoid concentration may protect against negative cannabis-related consequences in this population.

RESUMEN

BACKGROUND: Gay, bisexual, and other men-who-have-sex-with-men (GBMSM) continue to be disproportionately affected by Human Immunodeficiency Virus (HIV). Although HIV pre-exposure prophylaxis (PrEP) offers an effective means of reducing incident HIV among this population, the HIV-preventive success of oral-based PrEP is contingent upon regimen adherence. Elevated rates of alcohol-, substance use-, and mental health-related issues among GBMSM potentially hinder PrEP-taking efforts, however the evidence for this remains mixed. Accordingly, the present study entailed a comprehensive qualitative investigation to explore PrEP-prescribed GBMSM's perceptions surrounding the influence of alcohol, substance use, and mental health on PrEP adherence. METHODS: PrEP-prescribed GBMSM (age ≥ 18 years; prescribed PrEP for ≥ 3 months) were recruited from two PrEP-delivery clinics in Toronto, Canada for focus groups as part of the formative phase of an alcohol-, substance use-, and mental health-focused randomized controlled intervention trial. Focus group discussions qualitatively explored perceived strengths and barriers associated with adherence to PrEP treatment; with an emphasis on alcohol, substance use, and mental health concerns. Condom use among PrEP-prescribed GBMSM within the context of these concerns was also discussed. RESULTS: A total of five focus groups involving 35 GBMSM were conducted (4-10/group; mean age = 42.4; white = 71.4%). Although participants themselves generally reported successfully adhering to their PrEP regimens-resulting from a strong, underlying motivation for self-care-they recognized the detrimental impact that alcohol, substance use, and mental health had on adherence among their peers. In this regard, alcohol and substances were perceived as detracting from adherence only when consumption was excessive or temporally linked to PrEP dosing. Pronounced mental health issues (e.g., severe depression) were also seen as hindering adherence, although these effects were nuanced and perceived as person-dependent. Alcohol and substances were linked to condomless sex, regardless of PrEP use, and PrEP was therefore viewed as an HIV-protective 'safety net.' CONCLUSIONS: Overall, findings suggest that PrEP adherence can often be successfully achieved in the presence of alcohol-, substance use-, and mental health-related issues. Augmenting self-care, and addressing pronounced addictions- and mental health-related concerns, may enhance PrEP treatment among GBMSM.

RESUMEN

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.

RESUMEN

BACKGROUND: Although HIV pre-exposure prophylaxis (PrEP) substantially diminishes the likelihood of HIV acquisition, poor adherence can decrease the HIV-protective benefits of PrEP. The present investigation sought to identify the extent to which alcohol consumption, substance use, and depression were linked to PrEP nonadherence among gay, bisexual, and other men-who-have-sex-with-men (gbMSM). METHODS: gbMSM (age ≥ 18, prescribed PrEP for ≥3 months) were recruited from two clinics in Toronto, Canada for an e-survey assessing demographics; PrEP nonadherence (4-day PrEP-focused ACTG assessment); hazardous and harmful alcohol use (AUDIT scores of 8-15 and 16+, respectively); moderate/high risk substance use (NIDA M-ASSIST scores > 4); depression (CESD-10 scores ≥10); and other PrEP-relevant factors. The primary outcome, PrEP nonadherence, entailed missing one or more PrEP doses over the past 4 days. A linear-by-linear test of association assessed whether increasing severity of alcohol use (i.e., based on AUDIT categories) was linked to a greater occurrence of PrEP nonadherence. Univariate logistic regression was employed to determine factors associated with PrEP nonadherence, and factors demonstrating univariate associations at the p < .10 significance level were included in a multivariate logistic regression model. Additive and interactive effects involving key significant factors were assessed through logistic regression to evaluate potential syndemic-focused associations. RESULTS: A total of 141 gbMSM (Mean age = 37.9, white = 63.1%) completed the e-survey. Hazardous/harmful drinking (31.9%), moderate/high risk substance use (43.3%), and depression (23.7%) were common; and one in five participants (19.9%) reported PrEP nonadherence. Increasing alcohol use level was significantly associated with a greater likelihood of nonadherence (i.e., 15.6, 25.0, and 44.4% of low-risk, hazardous, and harmful drinkers reported nonadherence, respectively (χ2(1) = 4.79, p = .029)). Multivariate logistic regression demonstrated that harmful alcohol use (AOR = 6.72, 95%CI = 1.49-30.33, p = .013) and moderate/high risk cocaine use (AOR = 3.11, 95%CI = 1.01-9.59, p = .049) independently predicted nonadherence. Furthermore, an additive association emerged, wherein the likelihood of PrEP nonadherence was highest among those who were hazardous/harmful drinkers and moderate/high risk cocaine users (OR = 2.25, 95%CI = 1.19-4.25, p = .013). Depression was not associated with nonadherence. CONCLUSIONS: Findings highlight the need to integrate alcohol- and substance-focused initiatives into PrEP care for gbMSM. Such initiatives, in turn, may help improve PrEP adherence and reduce the potential for HIV acquisition among this group.

RESUMEN

BACKGROUND: People living with HIV (PLWH) who drink alcohol and use tobacco are particularly vulnerable to tobacco-induced diseases due to an already compromised immune system. This study investigated the prevalence and factors associated with tobacco use (cigarette and snuff) among PLWH who drink heavily. METHODS: Participants (n = 623) on antiretroviral therapy for HIV who reported heavy drinking using the Alcohol Use Disorders Identification Test (AUDIT) and AUDIT-C were recruited from six hospitals in Gauteng Province, South Africa. The Fagerström test was used to assess nicotine dependence. Chi Square tests and modified Poisson regression analyses were conducted to identify factors associated with tobacco use. RESULTS: Almost half of the participants reported ever smoking (44.0%; CI: 40.1-47.9) and about a quarter reported ever using snuff (25.5%; CI: 22.2-29.1). Current smokers and current snuff users comprised 27.3% (CI: 23.9-30.9) and 19.1% (CI: 16.2-22.3) of all participants respectively. Among current smokers, 37.9% (CI: 30.8-45.3) were moderately/highly dependent on nicotine. Current 'any tobacco product users' (ATPU: use cigarettes or snuff) were 45.4% (CI: 41.5-49.3) while 1.0% (CI: 0.4-2.0) currently used cigarettes and snuff. Adjusted regression analyses showed that, compared to males, females were less at risk of being: ever smokers (Relative Risk Ratio [RRR] = 0.33; CI: 0.27-0.41), current smokers (RRR = 0.18; CI: 0.12-0.25), and ATPU (RRR = 0.75; CI: 0.63-0.89) but were more at risk of ever snuff use (RRR = 5.23; CI: 3.31-8.25), or current snuff use (RRR = 26.19; CI: 8.32-82.40) than males. Ever snuff users (RRR = 1.32; CI: 1.03-1.70), current snuff users (RRR = 1.40; CI: 1.03-1.89) and ATPU (RRR = 1.27; CI: 1.07-1.51) were more at risk of reporting significant depressive symptoms. We found no significant associations between smoking status and years on ART and viral load. CONCLUSION: There is a high prevalence of cigarette and snuff use among PLWH who drink heavily. Tobacco use cessation interventions tailored specifically for this population and according to their tobacco product of choice are urgently needed given their vulnerability to ill-health.

RESUMEN

BACKGROUND: Although it has been purported that HIV-positive individuals may experience a greater degree of intoxication than HIV-negative individuals following acute alcohol consumption, no research to date has empirically tested this supposition. The present investigation entailed a randomized controlled experiment to identify whether the administration of a weight-specified dose of alcohol would lead to differential blood alcohol concentrations (BACs) among HIV-positive versus HIV-negative men. METHODS: In a specialized barroom laboratory, 143 men (n = 76 HIV-positive and n = 67 HIV-negative; mean age = 42.9) consumed beverages based on a formulation of 0.7 g alcohol/kg body weight over a 15-minute time frame. BAC was assessed via breathalyzer at 2 set time points (10 and 13 minutes postconsumption) and then periodically until detoxification (BAC < 0.040%). Primary outcomes included (i) area under the curve (AUC), calculated based on all of one's BAC readings, (ii) "BAC-EXP," defined as one's BAC reading 13 minutes postconsumption, and (iii) BAC-PEAK, defined as one's highest recorded BAC reading. RESULTS: Contrary to predictions, AUC (t(141) = 2.23, p = 0.027), BAC-EXP (t(141) = 2.68, p = 0.008), and BAC-PEAK (t(141) = 2.29, p = 0.023) were significantly lower among HIV-positive versus HIV-negative participants. These effects were sustained in multivariable models controlling for age, race, and AUDIT-based hazardous drinking classification. Among the HIV-positive sample, outcomes did not significantly differ based on HIV viral load detectability, antiretroviral therapy (ART) status, or ART adherence. CONCLUSIONS: The administration of a controlled, weight-specified dose of alcohol led to lower BACs among HIV-positive versus HIV-negative participants. These differences might derive from decreased body fat percentage and delayed gastric emptying associated with HIV seropositivity; however, additional research is necessary to verify these mechanisms. Unique alcohol dosing formulas based on HIV serostatus may be required in future alcohol administration experiments involving HIV-positive samples.

RESUMEN

Background: HIV-related stigma is associated with health consequences among people living with HIV, including increased risk for alcohol problems. Theory suggests that maladaptive coping may mediate the relationship between HIV-related stigma and alcohol outcomes, and these variables may be bidirectionally associated over time. However, no studies have examined the temporal relationships among these variables in people living with HIV. Purpose: This study examined prospective bidirectional and mediated associations among HIV-related stigma, maladaptive coping, and alcohol use severity in patients enrolled in the Ontario HIV Treatment Network Cohort study. Method: Patients receiving care for HIV (N = 1,520) at one of several clinics completed self-report measures annually. Data were analyzed in a four-wave, cross-lagged panel model. Results: Greater HIV-related stigma at each wave consistently predicted increased maladaptive coping 1 year later. Similarly, maladaptive coping consistently predicted greater subsequent HIV-related stigma. Further, we observed some evidence that maladaptive coping mediated the prospective associations between HIV-related stigma and alcohol use severity in both directions (i.e., stigma to subsequent alcohol use severity and vice versa) although these associations were not observed across all waves. Conclusion: Results suggest that HIV-related stigma and maladaptive coping are bidirectionally associated with one another over time. This study also provides some evidence that coping may be a relevant mediator of these associations, although findings were less consistent for mediated pathways. Future research should examine whether interventions addressing stigma and coping among people living with HIV may help to minimize health risks such as hazardous drinking.

RESUMEN

This investigation sought to identify HIV-risk and -protective factors among men-who-have-sex-with-men (MSM) who engaged in anal sex following alcohol or substance use during an international Pride Festival. MSM attending World Pride were surveyed regarding (1) alcohol, substance use, and sex during the past 24 h; and (2) HIV-risk and -protective factors. Valid data were provided by 1123 MSM. Anal sex was reported by 195 MSM, among whom the majority (n = 105) consumed alcohol or substances prior to sex. Among MSM aware of their HIV status who consumed alcohol or substances prior to sex (n = 99), those who engaged in serodiscordant condomless anal sex (n = 22) were more likely to be HIV+ (AOR = 10.14, 95% CI 1.48-69.35); report multiple sex partners (AOR = 9.05, 95% CI 1.70-48.12); and possess lower condom efficacy (AOR = 0.47, 95% CI 0.23-0.93) and social support (AOR = 0.08, 95% CI 0.01-0.46). Bolstering condom negotiation skills and social support could potentially reduce HIV acquisition/transmission-risk behavior, even when under the influence of alcohol or substances.

RESUMEN

The present study investigated the associations among alcohol use, socioeconomic status (SES), and human immunodeficiency virus (HIV) status, in the South African context. It was hypothesized that SES (predictor; measured as median split asset score) and alcohol use in the past 12 months (predictor) would interact such that current drinkers of low SES would be at an increased risk of testing HIV-positive (outcome). Nationally representative, cross-sectional survey data from 2005 (N = 16,110), 2008 (N = 13,055), and 2012 (N = 25,979) were analyzed using multinomial regression models. Current drinkers of low SES had an elevated risk of HIV infection in all survey years, ranging from a relative risk ratio (RRR) of 1.94 (95% confidence interval (CI) 1.29-3.00, t = 2.93, p = 0.002) in 2012 to RRR of 3.51 (95% CI 2.02-6.08, t = 4.47, p < 0.001) in 2008. Targeting preventive strategies to alcohol users of low SES could help reduce HIV burden and associated socioeconomic differences.

RESUMEN

Although hazardous/harmful alcohol use impacts response to HIV treatment, there have been few attempts to deliver alcohol-reduction interventions within South African HIV treatment services. As a first step towards implementing alcohol-focused interventions in these settings, we explored patients' views of the acceptability of a brief motivational interviewing and problem-solving intervention. In-depth interviews were conducted with 11 patients recruited from three HIV treatment sites in Tshwane, South Africa, who had completed the intervention. Participants noted that the intervention was acceptable and appropriate. As a result of the intervention, participants reported less use of alcohol as a coping mechanism. They described greater use of problem-focused and emotional coping strategies for dealing with mutable and immutable problems, respectively. Their only recommendation for improving the intervention was the addition of booster sessions. Findings suggest that this intervention is acceptable to patients receiving HIV treatment and is perceived to be helpful for reducing their use of alcohol.

RESUMEN

In the first part of this review, the nature of the associations between alcohol use and HIV/AIDS is discussed. Alcohol use has been found to be strongly associated with incidence and progression of HIV/AIDS, but the extent to which this association is causal has traditionally remained in question. Experiments where alcohol use has been manipulated as the independent variable have since helped establish a causal effect of alcohol use on the intention to engage in condomless sex. As the intention to engage in condomless sex is a surrogate measure of actual condom use behavior, which itself is linked to HIV incidence and re-infection, the causal chain has been corroborated. Moreover, there are biological pathways between alcohol use and the course of HIV/AIDS, only in part being mediated by adherence to antiretroviral medication. In the second part of the contribution, we provide suggestions on the quantification of the link between alcohol use and HIV incidence, using risk relations derived from experimental data. The biological links between alcohol use and course of HIV/AIDS are difficult to quantify given the current state of knowledge, except for an operationalization for the link via adherence to medication based on meta-analyses. The suggested quantifications are exemplified for South Africa.

RESUMEN

Although alcohol consumption is frequently perceived as a driver of condomless sex and subsequent HIV acquisition, the causal nature of this relationship remains unclear, and little is known about alcohol's direct versus indirect impact on the sexual risk dynamics of those who are HIV-positive. To address this gap, we present the protocol for an in-progress NIAAA-funded controlled experiment, wherein a sample of HIV-positive men-who-have-sex-with-men (MSM) undergoes an alcohol consumption manipulation (alcohol/placebo/control) and sexual arousal induction (sexually aroused/non-aroused), and then reports intentions to engage in condom-protected and condomless sexual acts with hypothetical sexual partners differing in HIV serostatus (HIV+/HIV-/HIV status unknown), condom use preference (use/don't use/not stated), and physical attractiveness (attractive/unattractive). Study outcomes will identify alcohol's impact on HIV-positive MSM's condomless sex intentions in the context of experimentally-manipulated factors as well as risk-relevant personality traits and alcohol-related expectancies. Detailed experimental procedures, ethical considerations, and potential implications for HIV prevention are discussed.

RESUMEN

Although adherence is an important key to the efficacy of antiretroviral therapy (ART), many people living with HIV (PLWH) fail to maintain optimal levels of ART adherence over time. PLWH with the added burden of Hepatitis C virus (HCV) coinfection possess unique challenges that potentially impact their motivation and ability to adhere to ART. The present investigation sought to (1) compare ART adherence levels among a sample of HIV/HCV-coinfected versus HIV-monoinfected patients, and (2) identify whether ART-related clinical and psychosocial correlates differ by HCV status. PLWH receiving ART (N = 215: 105 HIV/HCV-coinfected, 110 HIV-monoinfected) completed a comprehensive survey assessing ART adherence and its potential correlates. Medical chart extraction identified clinical factors, including liver enzymes. Results demonstrated that ART adherence did not differ by HCV status, with 83.7% of coinfected patients and 82.4% of monoinfected patients reporting optimal (i.e., ≥95%) adherence during a four-day recall period (p = .809). Multivariable logistic regression demonstrated that regardless of HCV status, optimal ART adherence was associated with experiencing fewer adherence-related behavioral skills barriers (AOR = 0.56; 95%CI = 0.43-0.73), lower likelihood of problematic drinking (AOR = 0.15; 95%CI = 0.04-0.67), and lower likelihood of methamphetamine use (AOR = 0.14; 95%CI = 0.03-0.69). However, among HIV/HCV-coinfected patients, optimal adherence was additionally associated with experiencing fewer ART adherence-related motivational barriers (AOR = 0.23; 95%CI = 0.08-0.62) and lower likelihood of depression (AOR = 0.06; 95%CI = 0.00-0.84). Findings suggest that although HIV/HCV-coinfected patients may face additional, distinct barriers to ART adherence, levels of adherence commensurate with those demonstrated by HIV-monoinfected patients might be achievable if these barriers are addressed.

RESUMEN

Sexual arousal has emerged as an important contextual feature in sexual encounters that can impact safer-sex decision-making. We conducted two experiments that investigated the effects of sexual arousal among male and female participants. Experiment 1 (N = 144) examined the impact of sexual around on sexual health decision-making. Sexually explicit and neutral video clips as well as hypothetical romantic scenarios were used to evaluate the effects of sexual arousal on sexual risk-taking intentions. Men and women who reported higher levels of sexual arousal also displayed greater intentions to participate in risky sexual behavior (e.g., unprotected sex with a new sex partner). Experiment 2 (N = 122) examined the impact of sexual arousal on general risk-taking, using the same videos clips as in Experiment 1 and a modified version of a computerized Blackjack card game. Participants were offered a chance to make either a risky play or a safe play during ambiguous conditions. Increased sexual arousal in Experiment 2 was associated with impulsivity and a greater willingness to make risky plays in the Blackjack game. These findings suggest that, in situations where there are strong sexually visceral cues, both men and women experiencing strong sexual arousal may have lower inhibitions and may experience impaired decision-making. This phenomenon may have an impact during sexual encounters and may contribute to a failure to use appropriate prophylactic protection.

RESUMEN

The present investigation involved a systematic literature review to (1) identify associations between personality constructs and unprotected sex among people living with HIV/AIDS (PLWH); (2) assess patterns of direct versus indirect personality-risky sex associations; and (3) explore possible differences in personality-risky sex associations among PLWH versus non-infected populations. Among the 26 studies yielded through the systematic search, sensation seeking and sexual compulsivity were the constructs most frequently examined, with fewer studies investigating traditional personality typologies. Personality constructs that were more conceptually proximal to the sexual act, such as sexual compulsivity and sex-related sub-components of sensation seeking, showed relatively direct associations with unprotected sex, whereas more conceptually distal constructs such as generalized impulsivity demonstrated only weak or indirect associations. Associations were also frequently mediated by other risk factors, including perceived responsibility and substance use. These findings have implications for the development of interventions to reduce high risk sexual behavior among PLWH.

The aim of this investigation was to identify factors associated with HIV transmission risk behavior among HIV-positive women and men receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. Across 16 clinics, 1,890 HIV+ patients on ART completed a risk-focused audio computer-assisted self-interview upon enrolling in a prevention-with-positives intervention trial. Results demonstrated that 62 % of HIV-positive patients' recent unprotected sexual acts involved HIV-negative or HIV status unknown partners. For HIV-positive women, multivariable correlates of unprotected sex with HIV-negative or HIV status unknown partners were indicative of poor HIV prevention-related information and of sexual partnership-associated behavioral skills barriers. For HIV-positive men, multivariable correlates represented motivational barriers, characterized by negative condom attitudes and the experience of depressive symptomatology, as well as possible underlying information deficits. Findings suggest that interventions addressing gender-specific and culturally-relevant information, motivation, and behavioral skills barriers could help reduce HIV transmission risk behavior among HIV-positive South Africans.

RESUMEN

Social and structural factors including HIV stigma are theorized to drive global disparities in HIV prevalence. This study tests whether HIV self-stigma, or experiences of stigma at the individual level, is associated with engagement in unprotected sex among people living with HIV (PLWH) in KwaZulu-Natal, South Africa, where 37.4% of adults are living with HIV compared with 0.8% worldwide. It further explores whether depressive symptoms, HIV status disclosure to sex partners, and/or condom use attitudes mediate potential associations between HIV self-stigma and unprotected sex. Participants, including 924 PLWH, were recruited from primary care clinics and completed baseline, 6-, 12-, and 18-month survey assessments between 2008 and 2011. Hierarchical linear modeling analyses were used to examine longitudinal within-subjects associations between HIV self-stigma, mediators, and unprotected sex with both HIV-negative/unknown and HIV-positive partners. Results demonstrate that HIV self-stigma was prospectively associated with greater likelihood of unprotected sex with HIV-negative/unknown partners. None of the variables explored significantly mediated this association. HIV self-stigma was also prospectively associated with greater likelihood of unprotected sex with HIV-positive partners via the mediators of greater depressive symptoms and more negative condom use attitudes. The current study suggests that HIV self-stigma undermines HIV secondary prevention and care efforts among PLWH in KwaZulu-Natal. It is therefore critical to address HIV stigma at the social/structural level to reduce HIV self-stigma at the individual level and ultimately curb global disparities in HIV prevalence. In the absence of widespread social/structural change, interventions that treat depressive symptoms and encourage more positive condom use attitudes despite the existence of HIV stigma may buffer associations between HIV self-stigma and unprotected sex with HIV-positive partners among PLWH in KwaZulu-Natal.

RESUMEN

BACKGROUND: Little research has examined whether alcohol reduction interventions improve antiretroviral therapy (ART) adherence and HIV treatment outcomes. This study assesses the efficacy of an intervention for reducing alcohol use among HIV patients on ART who are hazardous/harmful drinkers. Specific aims include adapting a blended Motivational Interviewing (MI) and Problem Solving Therapy (PST) intervention for use with HIV patients; evaluating the efficacy of the intervention for reducing alcohol consumption; and assessing counsellors' and participants' perceptions of the intervention. METHODS/DESIGN: A randomised controlled trial will evaluate the intervention among ART patients in public hospital-based HIV clinics in Tshwane, South Africa. We will recruit patients who are HIV-positive, on ART for at least 3 months, and classified as harmful/hazardous drinkers using the AUDIT-3. Eligible patients will be randomly assigned to one of three conditions. Patients in the experimental group will receive the MI-PST intervention to reduce harmful/hazardous alcohol use. Patients in the equal-attention wellness intervention group will receive an intervention focused on addressing health risk behaviours. Patients in the control condition will receive treatment as usual. Participants will complete an interviewer-administered questionnaire at baseline and 3, 6 and 12 months post-randomisation to assess alcohol consumption, ART adherence, physical and mental health. We will also collect biological specimens to test for recent alcohol consumption, CD4 counts and HIV RNA viral loads. The primary outcome will be reduction in the volume of alcohol consumed. Secondary outcomes include reduction in harmful/hazardous use of alcohol, reduction in biological markers of drinking, increase in adherence rates, reductions in viral loads, and increases in CD4 T-cell counts. A process evaluation will ascertain counsellors' and participants' perceptions of the acceptability and effectiveness of the interventions. DISCUSSION: We have obtained ethical approval and approval from the study sites and regional and provincial health departments. The study has implications for clinicians, researchers and policy makers as it will provide efficacy data on how to reduce harmful/hazardous alcohol consumption among HIV patients and will shed light on whether reducing alcohol consumption impacts on HIV treatment adherence and other outcomes.

RESUMEN

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.

RESUMEN

Little is known regarding factors implicated in early engagement and retention in HIV care among individuals not yet eligible for antiretroviral therapy (pre-ART) in sub-Saharan Africa. Identifying such factors is critical for supporting retention in pre-ART clinical care to ensure timely ART initiation and optimize long-term health outcomes. We assessed patients' pre-ART HIV care-related information, motivation, and behavioral skills among newly diagnosed ART-ineligible patients, initiating care in KwaZulu-Natal, South Africa. The survey was interviewer-administered to eligible patients, who were aged 18 years or older, newly entering care (diagnosed within the last six-months), and ineligible for ART (CD4 count > 200 cells/mm(3)) in one of four primary care clinical sites. Self-reported information, motivation, and behavioral skills specific to retention in pre-ART HIV-care were characterized by categorizing responses into those reflecting potential strengths and those reflective of potential deficits. Information, motivation, and behavioral skills deficits sufficiently prevalent in the overall sample (i.e.,≥30% prevalent) were identified as areas in need of specific attention through intervention efforts adapted to the clinic level. Gender-based differences were also evaluated. A total of 288 patients (75% female) completed structured interviews. Across the sample, eight information, eight motivation, and eight behavioral skills deficit areas were identified as sufficiently prevalent to warrant specific targeted attention. Gender differences did not emerge. The deficits in pre-ART HIV care-related information, motivation, and behavioral skills that were identified suggest that efforts to improve accurate information on immune function and HIV disease are needed, as is accurate information regarding HIV treatment and transmission risk prior to ART initiation. Additional efforts to facilitate the development of social support, including positive interactions with clinic staff and decreasing community-level stigma and to decrease structural and resource-depleting demands of HIV care may be particularly valuable to facilitate retention in pre-ART HIV care.
