RESUMEN

Few studies have examined the association between healthcare utilization and heavy alcohol use in Russia among persons with HIV (PWH), a group with high healthcare needs. This study analyzed the association between unhealthy alcohol use (defined as AUDIT score ≥ 8) and healthcare utilization among PWH with heavy alcohol use and daily smoking in St. Petersburg, Russia. This secondary analysis used data from a randomized controlled trial addressing alcohol use. The primary outcome was seeing an infectionist for HIV care in the past year. Outcomes were measured at baseline, 6 months, and 12 months. We assessed the association between unhealthy alcohol use and healthcare utilization outcomes with a repeated measures logistic regression model, controlling for relevant covariates. Nearly all (96.0%) participants had unhealthy alcohol use at baseline, and 90.0% had seen an infectionist for HIV care in the past year. In adjusted analyses, unhealthy alcohol use was associated with a 36% decrease in seeing an infectionist for HIV care (aOR = 0.64, 95% CI 0.43-0.95). Participants reported low levels of emergency department visits and hospitalizations. Understanding how to engage this population in alcohol use disorder treatment and HIV care is an important next step for improving health outcomes for this population.

RESUMEN

Lack of access to resources is a "fundamental cause" of poor HIV outcomes across the care cascade globally and may have the greatest impact on groups with co-existing marginalized identities. In a sample of people living with HIV (PWH) who inject drugs and were not on antiretroviral therapy (ART), we explored associations between access to resources and HIV severity. Fundamental Cause Theory (FCT) sees socioeconomic status/access to resources as a root cause of disease and emphasizes that individuals with limited resources have fewer means to mitigate health risks and implement protective behaviors, which ultimately generates disparities in health outcomes. Guided by the FCT, we hypothesized that resource depletion (primary aim) and lower income (secondary aim) were associated with increased HIV severity. Using baseline data from the Linking Infectious and Narcology Care (LINC-II) trial of ART-naive PWH who inject drugs in St. Petersburg, Russia (n = 225), we examined the association between "past year resource runout" (yes vs. no) and "low-income (< 300 USD a month)" and the outcome HIV severity (CD4 count, continuous). We fit two separate linear regression models adjusted for gender, age, time since HIV diagnosis, and prior ART use. Participants had a mean age of 37.5 years and were 60% male. Two thirds (66%) reported resource depletion, and 30% had income below 300 USD a month. Average CD4 count was 416 cells/mm3 (SD 285). No significant association was identified between either resource depletion or low-income and HIV severity (adjusted mean difference in CD4 count for resource depletion: - 4.16, 95% CI - 82.93, 74.62; adjusted mean difference in CD4 count for low-income: 68.13, 95% CI - 15.78, 152.04). Below-average income and running out of resources were common among PWH who inject drugs and are not on ART in St. Petersburg, Russia. Resource depletion and low-income were not significantly associated with HIV disease severity as captured by CD4 count. The nuanced relationship between socioeconomic status and HIV severity among people with HIV who inject drugs and not on ART merits further examination in a larger sample.

RESUMEN

Achieving abstinence from alcohol, tobacco, or both may improve mental health, but is understudied in people with HIV (PWH). The St PETER HIV randomized clinical trial compared varenicline, cytisine, and nicotine replacement therapy on alcohol and smoking behavior among 400 PWH in Russia. The primary exposure was thirty-day point prevalence abstinence (PPA) from (1) alcohol, (2) smoking, (3) both, or (4) neither and was assessed at 1, 3, 6 and 12-months as were the study outcomes of anxiety (GAD-7) and depressive (CES-D) symptoms. The primary aim was to examine the association between smoking and/or alcohol abstinence and subsequent symptoms of depression and anxiety. Primary analysis used repeated measures generalized linear modeling to relate PPA with mental health scores across time. In secondary analyses, Kruskal-Wallis tests related PPA with mental health scores at each timepoint. Primary analyses did not identify significant differences in anxiety or depressive symptoms between exposure groups over time. Secondary analyses found CES-D scores across PPA categories were similar at 1-month (11, 10, 11, 11) and 6-months (10, 10, 11, 11) but differed at 3-months (9, 11, 10, 12; p = 0.035) and 12-months (10, 6, 11, 10; p = 0.019). GAD-7 scores did not vary across PPA categories at any time point. While abstinence was associated with fewer depressive symptoms at times, findings were not consistent during follow-up, perhaps reflecting intermittent relapse. PWH with polysubstance use and mental health comorbidity are complex, and larger samples with sustained abstinence would further elucidate effects of abstinence on mental health.

RESUMEN

People with HIV (PWH) who inject drugs often experience coexisting HIV- and substance use-related stigma manifestations. We assessed correlates of HIV stigma (Berger HIV stigma scale), substance use stigma (Substance Abuse Self-stigma scale) and intersectional HIV and substance use stigma in a cohort of PWH with a lifetime history of drug use in St. Petersburg, Russia. Intersectional stigma was defined as having a score greater than the median for both forms of stigma. Of the 208 participants, 56 (27%) had intersectional stigma. Depressive symptoms and alcohol dependence were significantly associated with a higher HIV and substance stigma score, but not with intersectional stigma. Individual and community interventions to reduce the impact of HIV stigma and substance use stigma affecting PWH who inject drugs should consider assessing and addressing mental health and unhealthy substance use. Further work with longitudinal data is needed to understand mechanisms leading to intersectional stigma.


RESUMEN: Las personas infectadas por el VIH que se inyectan drogas a menudo experimentan manifestaciones de estigma relacionadas con el uso de sustancias y el propio VIH. En este estudio evaluamos los correlatos de estigma asociado al VIH (escala de estigma asociado al VIH de Berger), el estigma asociado al uso de sustancias ("Substance Abuse Self-stigma Scale") y el estigma interseccional del VIH y el uso de sustancias en una cohorte de personas infectadas por el VIH con antecedente de uso de drogas en San Petersburgo, Rusia. El estigma interseccional se definió como una puntuación superior a la mediana para ambas formas de estigma. De los 208 participantes, 56 (27%) tenían estigma interseccional. Los síntomas depresivos y la dependencia del alcohol se asociaron significativamente con una puntuación más alta de estigma relacionado con el VIH y las sustancias, pero no con el estigma interseccional. Las intervenciones individuales y comunitarias para reducir el impacto del estigma asociado al VIH y al uso de sustancias que afectan a las personas con VIH que se inyectan drogas deben tener en cuenta la salud mental y el uso nocivo de sustancias. Se necesitan estudios con datos longitudinales para comprender mejor los mecanismos que conducen al estigma interseccional.

RESUMEN

Food insecurity (FI) impacts people with HIV (PWH) and those who use substances (i.e. drugs and alcohol). We evaluated the longitudinal association between FI and HIV transmission risks (unprotected sexual contacts and shared needles/syringes). Among 351 PWH who use substances in Russia, 51.6% reported FI and 37.0% past month injection drug use. The mean number of unprotected sexual contacts in the past 90 days was 13.4 (SD 30.1); 9.7% reported sharing needles/syringes in the past month. We did not find a significant association between mild/moderate FI (adjusted IRR = 0.87, 95% CI 0.47, 1.61) or severe FI (aIRR = 0.84, 95% CI 0.46, 1.54; global p = 0.85) and unprotected sexual contacts. We observed a significant association between severe FI and sharing needles/syringes in the past month (adjusted OR = 3.27, 95% CI 1.45, 7.39; p = 0.004), but not between mild/moderate FI and sharing needles/syringes in the past month (aOR = 1.40,95% CI 0.58, 3.38; p = 0.45). These findings suggest that severe FI could be a potential target for interventions to lower HIV transmission.


RESUMEN: La inseguridad alimentaria (IF) afecta a las personas que viven con VIH (PVV y a personas con abuso desustancias (.ej. drogas y alcohol). Evaluamos la asociación longitudinal entre la IF y los riesgos de transmisión del VIH (relaciones sexuales sin protección y agujas/jeringas compartidas). Entre 351 PVVcon abuso de sustancias en Rusia, el 51,6% reportó FI y el 37,0% consumió drogas intravenosas en el último mes. El promedio de contactos sexuales sin protección en los últimos 90 días fue de 13,4 (DE 30,1); el 9,7% informó haber compartido agujas/jeringas en el último mes. No encontramos una asociación significativa entre IF leve/moderada (IRR ajustada = 0,87, IC 95% = 0,47, 1,61) o IF grave (IRRa = 0,84, IC 95% = 0,46, 1,54; p global = 0,85) y relaciones sexuales sin protección. Observamos una asociación significativa entre IF grave y compartir agujas/jeringas en el último mes (OR ajustado = 3,27, IC 95% = 1,45, 7,39; p = 0,004), pero no entre IF leve/moderada y compartir agujas/jeringas en el último mes (ORa = 1,40, IC 95% = 0,58, 3,38; p = 0,45). Estos hallazgos sugieren que la IF grave podría ser un enfoque para intervenciones que buscan reducir la transmisión del VIH.

RESUMEN

Providers' disrespect and abuse of patients is a recognized but understudied issue affecting quality of care and likely affecting healthcare utilization. Little research has examined this issue among people living with HIV (PWH) who inject drugs, despite high stigmatization of this population. No research has examined this issue in the context of Russia. This study assesses patients' reports of disrespect and abuse from providers as a barrier to healthcare and examines the association between these reports and HIV care outcomes.We conducted a cross-sectional analysis of the associations between disrespect/abuse from health providers as a barrier to care and the following HIV care outcomes: (i) anti-retroviral treatment (ART) uptake ever, (ii) past 6-month visit to HIV provider, and (iii) CD4 count. Participants (N = 221) were people living with HIV who injected drugs and were not on ART at enrollment.Two in five participants (42%) reported a history disrespect/abuse from a healthcare provider that they cited as a barrier to care. Those reporting this concern had lower odds of ever use of ART (adjusted odds ratio 0.46 [95% CI 0.22, 0.95]); we found no significant associations for the other HIV outcomes. We additionally found higher representation of women among those reporting prevalence of disrespect/abuse from provider as a barrier to care compared to those not reporting this barrier (58.1% versus 27.3%).Almost half of this sample of PWH who inject drugs report disrespect/abuse from a provider as a barrier to healthcare, and this is associated with lower odds of receipt of ART but not with other HIV outcomes studied. There is need for improved focus on quality of respectful and dignified care from providers for PWH who inject drugs, and such focus may improve ART uptake in Russia.

RESUMEN

This study evaluated the association between impulsivity and linkage to HIV care among Russians living with HIV recruited from an inpatient narcology hospital. Linking Infectious and Narcology Care (LINC) study participants who completed the Barratt Impulsiveness Scale (BIS) were included in these analyses. The primary independent variable was impulsivity score which was categorized as high impulsivity (BIS score > 71) vs. low impulsivity (BIS score < = 71). The primary outcome, linkage to care post recruitment, was defined as one or more HIV medical care visits at 12-month follow-up. Multiple logistic regression models were used to evaluate the association between high impulsivity and linkage to HIV care controlling for potential confounders. Participants (N = 227) were adults with a mean age of 34 years (SD = 5), and the majority were male (74%). We did not detect a significant association between impulsivity and linkage to HIV care after adjusting for respondents' age, gender, CD4 cell count, and depression score. We also found that substance use and hazardous drinking did not appear to confound the relationship. Although our study was unable to detect an association between impulsivity and linkage to HIV care, it may provide direction for future research exploring the associations between impulsivity and HIV care.

RESUMEN

This study describes the self-reported prevalence of hepatitis C virus (HCV) coinfection and the HCV care continuum among persons enrolled in the St PETER HIV Study, a randomized controlled trial of medications for smoking and alcohol cessation in HIV-positive heavy drinkers and smokers in St. Petersburg, Russia. Baseline health questionnaire data were used to calculate proportions and 95% confidence intervals for self-reported steps along the HCV continuum of care. The cohort included 399 HIV-positive persons, of whom 387 [97.0% (95% CI 95.3-98.7%)] reported a prior HCV test and 315 [78.9% (95% CI 74.9-82.9%)] reported a prior diagnosis of HCV. Among those reporting a diagnosis of HCV, 43 [13.7% (95% CI 9.9-17.4%)] had received treatment for HCV, and 31 [9.8% (95% CI 6.6-13.1%)] had been cured. Despite frequent HCV testing in this HIV-positive Russian cohort, the proportion reporting prior effective HCV treatment was strikingly low. Increased efforts are needed to scale-up HCV treatment among HIV-positive Russians in St. Petersburg.

RESUMEN

Little is known about the intersection of HIV stigma and substance use stigma. Using data from 188 HIV-positive people who inject drugs (PWID) in Russia, we examined the associations of these stigmas and their interaction with access and utilization of healthcare. While substance use stigma was significantly associated with poor access to care (AOR 2.31, 95%CI 1.50-3.57), HIV stigma was not. HIV stigma was associated with lower inpatient care utilization (AOR 0.32, 95%CI 0.14-0.65), while substance use stigma was not. We did not detect a significant interaction between the two forms of stigma for either of the primary outcomes. However, those with high levels of both substance use stigma and HIV stigma had higher odds of poor general access to healthcare (AOR 1.86, 95%CI 1.19-2.92), and lower odds of recent general outpatient (AOR 0.52, 95%CI 0.32-0.85) and any inpatient (AOR 0.48, 95%CI 0.22-0.99) care utilization compared to those with low levels of both types of stigma. Interventions addressing both substance use and HIV stigma in general healthcare settings might improve care in this HIV key population.

RESUMEN

BACKGROUND AND OBJECTIVES: Previous findings on the association between hazardous drinking and HIV-risk behavior have been equivocal, varying by population and individual difference factors. This study examined associations between hazardous drinking, impulsivity, and HIV-risk behaviors among HIV-positive Russian patients with a history of injection drug use (IDU), not on antiretroviral therapy. METHODS: Negative binomial regression analyses of data from a randomized controlled trial were performed (N = 241). Main independent variables were the Alcohol Use Disorders Identification Test and the Barratt Impulsiveness Scale. Outcomes were number of condomless sexual episodes (CSE; primary), number of sexual partners, and needle-sharing frequency (secondary). RESULTS: Hazardous drinking was positively associated with the frequency of CSE (adjusted incidence rate ratio [aIRR] = 2.16, 95% confidence interval [CI], 1.98-2.36). Moderate (aIRR = 0.51, 95% CI, 0.46-0.56) and high (aIRR = 0.66, 95% CI, 0.60-0.73) impulsivity were associated with fewer CSE compared with low impulsivity. Hazardous drinking (aIRR = 0.64, 95% CI, 0.52-0.79) and impulsivity (aIRR = 0.95, 95% CI, 0.94-0.96) were both associated with fewer sexual partners. Hazardous drinking and impulsivity were each associated with increased needle sharing. The association between hazardous drinking and number of needle-shares was strongest at higher impulsivity levels. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Hazardous drinking may be a risk factor for CSE among HIV-positive Russian patients and may influence needle sharing. Findings contribute to our understanding of the interactive associations between hazardous drinking and impulsivity with sexual risk behaviors and needle sharing among HIV-positive Russian patients with a history of IDU. (Am J Addict 2020;00:00-00).

RESUMEN

We provide an overview of the recent achievements in psychiatric genetics research in the Russian Federation and present genotype-phenotype, population, epigenetic, cytogenetic, functional, ENIGMA, and pharmacogenetic studies, with an emphasis on genome-wide association studies. The genetic backgrounds of mental illnesses in the polyethnic and multicultural population of the Russian Federation are still understudied. Furthermore, genetic, genomic, and pharmacogenetic data from the Russian Federation are not adequately represented in the international scientific literature, are currently not available for meta-analyses and have never been compared with data from other populations. Most of these problems cannot be solved by individual centers working in isolation but warrant a truly collaborative effort that brings together all the major psychiatric genetic research centers in the Russian Federation in a national consortium. For this reason, we have established the Russian National Consortium for Psychiatric Genetics (RNCPG) with the aim to strengthen the power and rigor of psychiatric genetics research in the Russian Federation and enhance the international compatibility of this research.The consortium is set up as an open organization that will facilitate collaborations on complex biomedical research projects in human mental health in the Russian Federation and abroad. These projects will include genotyping, sequencing, transcriptome and epigenome analysis, metabolomics, and a wide array of other state-of-the-art analyses. Here, we discuss the challenges we face and the approaches we will take to unlock the huge potential that the Russian Federation holds for the worldwide psychiatric genetics community.

RESUMEN

BACKGROUND: The multifactorial mechanisms driving negative health outcomes among risky drinkers with HIV may include immunosenescence. Immunosenescence, aging of the immune system, may be accentuated in HIV and leads to poor outcomes. The liver regulates innate immunity and adaptive immune tolerance. HIV-infected people have high prevalence of liver-related comorbidities. We hypothesize that advanced liver fibrosis/cirrhosis is associated with alterations in T-cell subsets consistent with immunosenescence. METHODS: ART-naïve people with HIV with a recent history of heavy drinking were recruited into a clinical trial of zinc supplementation. Flow cytometry was used to characterize T-cell subsets. The two primary dependent variables were CD8+ and CD4+ T-cells expressing CD28-CD57+ (senescent cell phenotype). Secondary dependent variables were CD8+ and CD4+ T-cells expressing CD45RO + CD45RA- (memory phenotype), CD45RO-CD45RA+ (naïve phenotype), and the naïve phenotype to memory phenotype T-cell ratio (lower ratios associated with immunosenescence). Advanced liver fibrosis/cirrhosis was defined as FIB-4 > 3.25, APRI≥1.5, or Fibroscan measurement ≥10.5 kPa. Analyses were conducted using multiple linear regression adjusted for potential confounders. RESULTS: Mean age was 34 years; 25% female; 88% hepatitis C. Those with advanced liver fibrosis/cirrhosis (N = 25) had higher HIV-1 RNA and more hepatitis C. Advanced liver fibrosis/cirrhosis was not significantly associated with primary or secondary outcomes in adjusted analyses. CONCLUSIONS: Advanced liver fibrosis/cirrhosis was not significantly associated with these senescent T-cell phenotypes in this exploratory study of recent drinkers with HIV. Future studies should assess whether liver fibrosis among those with HIV viral suppression and more advanced, longstanding liver disease is associated with changes in these and other potentially senescent T-cell subsets.

RESUMEN

BACKGROUND/AIMS: Reproducible outcomes in clinical trials depend on adherence to study protocol. Short message service (also known as text message) reminders have been shown to improve clinical trial adherence in the United States and elsewhere. However, due to systematic differences in mobile data plans, languages, and technology, these systems are not easily translated to international settings. METHODS: To gauge technical capabilities for international projects, we developed SMSMessenger, an automated Android application that uses a US server to send medication reminders to participants in a clinical trial in St. Petersburg, Russia (Zinc for HIV disease among alcohol users-a randomized controlled trial in the Russia Alcohol Research Collaboration on HIV/AIDS cohort). The application is downloaded once onto an Android study phone. When it is time for the text message reminders to be sent, study personnel access the application on a local phone, which in turn accesses the existing clinical trial database hosted on a US web server. The application retrieves a list of participants with the following information: phone number, whether a message should be received at that time, and the appropriate text of the message. The application is capable of storing multiple outgoing messages. With a few clicks, text messages are sent to study participants who can reply directly to the message. Study staff can check the local phone for incoming messages. The SMSMessenger application uses an existing clinical trial database and is able to receive real-time updates. All communications between the application and server are encrypted, and phone numbers are stored in a secure database behind a firewall. No sensitive data are stored on the phone, as outgoing messages are sent through the application and not by messaging features on the phone itself. Messages are sent simultaneously to study participants, which reduces the burden on local study staff. Costs and setup are minimal. The only local requirements are an Android phone and data plan. CONCLUSION: The SMSMessenger technology could be modified to be applied anywhere in the world, in any language, script, or alphabet, and for many different purposes. The novel application of this existing low-cost technology can improve the usefulness of text messaging in advancing the goals of international clinical trials.

RESUMEN

The gabapentinoid pregabalin is a rapid-acting anxiolytic and analgesic, possibly suitable in supervised opioid detoxification. However, clinicians have been cautious in using it because of its unknown addictive risk and rising number of mortalities after pregabalin self-medication in opioid abusers. Here, we studied interactions of pregabalin and morphine on reward functions of the dopamine system in mice and the efficacy of pregabalin on withdrawal in opioid addicts. After the treatment of mice with pregabalin and morphine, we used electrophysiology to study neuroplasticity in midbrain slices, self-administration and conditioned place preference tests to investigate the rewarding potential of pregabalin and naloxone-precipitated morphine withdrawal to evaluate opioid withdrawal symptoms. Further, we ran a pilot single-blind, randomized, controlled trial (34 heroin addicts) to evaluate the efficacy and safety of pregabalin in the treatment of opioid withdrawal syndrome. Pregabalin alone did not induce glutamate receptor neuroplasticity of dopamine neurons in the ventral tegmental area, but pre-treatment with pregabalin suppressed morphine-induced neuroplasticity, hyperlocomotion and morphine self-administration. Pregabalin administration after chronic morphine exposure failed to induce any rewarding effects. Instead, pregabalin suppressed withdrawal symptoms in both morphine-treated mice and opioid addicts and was well tolerated. Intriguingly, pregabalin administration after a low dose of morphine strongly facilitated ventral tegmental area neuroplasticity and led to increased conditioned place preference. Pregabalin appears to have the efficacy to counteract both reinforcing and withdrawal effects of opioids, but it also has a potentiating effect when given to mice with existing opioid levels.

RESUMEN

Food insecurity (FI) has been associated with HIV disease progression among people on antiretroviral therapy (ART), presumably a consequence of poor medication adherence. We assessed whether there is a longitudinal association between FI and two primary outcomes reflecting on HIV disease progression (i.e., CD4 count and time to ART initiation) among people not on ART. Analyses used linear mixed effects and Cox models controlling for confounders. In this cohort (n = 310) FI was common (53%). Most (71.3%) reported past month heavy alcohol use and 37.1% reported past month injection drug use. Only 50 participants initiated ART during the study and mean time to ART was 128 days (SD 120). There were no significant differences in CD4 cell count between the groups with mild/moderate FI or severe FI versus those with no FI [adjusted mean difference, mild/moderate insecurity versus no FI -32.5 (95% CI -94.3, 29.3); severe versus no FI -45.5 (95% CI -124.1, 33.0); global p = 0.42]. We found no significant association between FI and longer time to ART initiation (p = 0.36). Food security is a desirable goal for overall health and shown beneficial for those on ART, however it does not appear to be associated with HIV disease progression among those with high prevalence of substance use and not yet on ART.

RESUMEN

Unhealthy alcohol use, highly prevalent in the Russian Federation (Russia), is associated with HIV risk behaviors among people living with HIV (PLWH). HIV stigma contributes to the HIV risk environment in Russia. To examine HIV stigma among Russian PLWH and to explore its association with unhealthy alcohol use, we conducted a longitudinal analysis of 700 PLWH in St. Petersburg, Russia. We assessed the association between alcohol dependence and HIV stigma measured at baseline and 12 months follow-up. Participants with alcohol dependence (n = 446) reported significantly higher HIV stigma scores over time than those without dependence (n = 254) (adjusted mean difference 0.60, 95% CI 0.03-1.17; p = 0.04). In secondary analyses, we examined recent risky alcohol use and did not detect an association with HIV stigma. Alcohol dependence is associated with high HIV stigma among Russian PLWH but the nature of the association is conjectural. HIV prevention efforts in Russia that address alcohol use disorders hold potential to mitigate HIV-related stigma and its possible adverse effects among PLWH.

RESUMEN

We analyzed baseline data from an observational cohort of HIV-infected ART-naïve patients in St. Petersburg, Russia to explore whether pain was associated with HIV risk behaviors. The primary outcomes were (1) unprotected vaginal or anal sex in the past 90 days and (2) sharing of needles or equipment in the past month. Secondary outcomes included: use of alcohol prior to sex, current injection drug use, number of unprotected sex and sharing episodes, and days injected in the past month. The main independent variable was any past week pain. Multivariable regression models were fit for outcomes. After adjustment, the association with unprotected sex was of borderline significance (AOR = 2.06; 95 % CI 0.98-4.36, p = 0.058); there was no significant association between any past week pain and sharing of needles/equipment (AOR = 1.52; 95 % CI 0.65-3.59, p = 0.33). Participants with pain had higher odds of reporting alcohol use prior to sex (AOR = 2.42; 95 % CI 1.10-5.28, p = 0.03).

RESUMEN

The link between HIV stigma with substance use is understudied. We characterized individuals with high HIV stigma and examined whether HIV stigma contributes to substance use among HIV-positive Russians reporting risky alcohol use. We analyzed data from HERMITAGE, a randomized controlled trial of 700 people living with HIV/AIDS (PLWHA) with past 6-month risky sex and risky alcohol use in St. Petersburg, Russia (2007-2011). Participants who were female and reported depressive symptoms and lower social support were more likely to endorse high HIV stigma (all p's < 0.001). In adjusted models, high HIV stigma was not significantly associated with the primary outcome unhealthy substance use and was not consistently associated with secondary substance use outcomes. Interventions to enhance social and mental health support for PLWHA, particularly women, may reduce stigma, though such reductions may not correspond to substantial decreases in substance use among this population.

RESUMEN

Food insecurity (FI) is a documented problem associated with adverse health outcomes among HIV-infected populations. Little is known about the relationship between alcohol use and FI. We assessed whether heavy alcohol use was associated with FI among HIV-infected, antiretroviral therapy (ART)-naïve cohorts in Uganda and Russia. Inverse probability of treatment weighted logistic regression models were used to evaluate the association using cross-sectional baseline data. FI was experienced by half of the Russia cohort (52 %) and by a large majority of the Uganda cohort (84 %). We did not detect an association between heavy alcohol use and FI in either cohort (Russia: AOR = 0.80, 95 % CI 0.46, 1.40; Uganda: AOR = 1.00, 95 % CI 0.57, 1.74) or based on the overall combined estimate (AOR = 0.89, 95 % CI 0.60, 1.33). Future studies should explore the determinants of FI in HIV-infected populations to inform strategies for its mitigation.
