Self-reported and Point-of-Care Biomarkers of Substance Use Measures Among Older Adults with HIV from Low- and Middle-Income Countries
Measuring alcohol and other drug (AOD) use remains challenging in HIV care in low- and middle-income countries, where self-report and point-of-care (POC) urine biomarkers capture different time windows. Among 2,059 people with HIV aged 40 years or older across eight IeDEA clinics (2020 to 2022), we examined what self-reported AOD use (AUDIT, ASSIST) and POC urine tests (uEtG for alcohol; 5-panel drug screen) each capture. Self-report identified m…
Testing a systematically braided alcohol reduction and HIV status neutral intervention among people receiving STI care in Malawi
Background Heavy alcohol use is common in Malawi among people receiving sexually transmitted infections (STI) care and is a critical barrier to the success of HIV prevention and treatment efforts. Methods This protocol presents a pilot hybrid type 1 effectiveness-implementation trial evaluating the short-term effectiveness and implementation of a scalable evidence-based intervention (EBI) to reduce alcohol use and provide HIV prevention and treat…
Associations of hepatitis C virus (HCV) antibody positivity with opioid, stimulant, and polysubstance injection among people who inject drugs (PWID) in rural U.S. communities
HCV antibody positivity, indicating prior exposure, was highest among those who had recently injected opioids, alone or with stimulants. Additional nucleic acid testing is necessary to confirm active infection. More research is needed to determine the underlying causes of HCV antibody positivity by injection use
Geospatial and phylogenetic clustering of acute and recent HIV infections in Lilongwe, Malawi
HIV transmission during early HIV infection impedes efforts to end HIV as a public health threat, as diagnosis typically occurs after this period of elevated transmission risk. To guide diagnosis and prevention strategies, we evaluated the geospatial and phylogenetic clustering of acute and recent HIV infection in Lilongwe, Malawi. We identified people with acute (pre-seroconversion) HIV infection (AHI) and a random sample of people with post-acu…
“I'm tired of seeing my friends die”
PURPOSE: Participation in clinical trials among people who use drugs (PWUD) in rural areas remains disproportionately low compared to those in urban communities. Our objective was to describe the barriers and facilitators to clinical trial participation among this understudied and underserved population. METHODS: We conducted semi-structured in-depth interviews among rural PWUD in Kentucky, Ohio, and Oregon. Using the Ickovics and Meisler framewo…
Resilience to Stigma in Medical, Social, and Employment Contexts Among People Who Inject Drugs in Rural Ohio
People who inject drugs (PWID) experience stigma related to drug use and HIV prevention, which can impede engagement with the HIV prevention continuum. Resilience may buffer against stigma's harmful effects, but limited research has examined how resilience operates across different social contexts and stigma types among PWID. Using qualitative interviews and cognitive interviews, we adapted the 10-item Connor-Davidson Resilience Scale to measure …
Association of fentanyl test strip results and change in drug use behaviors
These findings suggest that FTS assist PWUD to immediately reduce their risks by changing drug use behaviors, including reducing the amount of drug used
Who Leads and Who Follows? The Pathways to Joint Attention During Free-Flowing Interactions Change Over Developmental Time
Joint attention (JA) has been found to correlate with many developmental outcomes. However, little is known about how naturalistic JA is established and develops during early infancy. In this study, free-flowing tabletop toy play between infants at 5 and 15 months and their mothers (N = 48 dyads; 65% white) was observed to (1) examine changes in JA, (2) investigate whether infants become better leaders or followers of JA, and (3) explore the role…
Availability of substance use screening and treatment within HIV clinical sites across seven geographic regions within the IeDEA consortium
Availability of screening and treatment for AUD/SUD in HIV care settings is limited, leaving a substantial gap for integration into ongoing HIV care. A critical understanding is needed of the multilevel implementation factors or feasible implementation strategies for integrating screening and treatment of AUD/SUD into HIV care settings, particularly for resource-constrained regions
Depression, Alcohol Use, and Sexual Behaviors by HIV Infection Stage and Diagnosis Timing Among STI Clinic Patients in Lilongwe, Malawi
Alcohol use as a mediator of the effect of two alcohol reduction interventions on mental health symptoms of ART clients in Vietnam
We aimed to examine the mediating role of alcohol use in the pathway from the interventions to depression and anxiety symptoms using data from a randomized controlled trial among people living with HIV (PWH) with hazardous alcohol use (n = 440) in Thai Nguyen, Vietnam. Participants were randomized into either a combined intervention (CoI), a brief intervention (BI) and a standard of care arm. Both interventions were based on cognitive behavioral …

“Now We Are Seeing the Tides Wash In”
Background: Ohio’s opioid epidemic continues to progress, severely affecting its rural Appalachian counties—areas marked by high mortality rates, widespread economic challenges, and a history of extreme opioid overprescribing. Substance use may be particularly prevalent in the region due to interactions between community and interpersonal trauma. Purpose/Objectives: We conducted qualitative interviews to explore the local context of the epidemic …
Effects of Two Alcohol Reduction Interventions on Depression and Anxiety Symptoms of ART Clients in Vietnam
Depressive Symptoms, Gender, Disclosure, and HIV Care Stage Among People Living with HIV in Cameroon
Heavy episodic drinking and HIV disclosure by HIV treatment status among People with HIV in IeDEA Cameroon
The prevalence of recent HED was high among PWH in care. HED prevalence was highest among men and recent ART initiators. Longitudinal analyses should explore how HIV disclosure may support PWH in reducing or abstaining from HED through social support. Systematic HED screening and referral to care should be included in routine HIV clinical care, particularly for men, to improve engagement in the HIV care continuum in Cameroon
Longitudinal Analysis of Depressive Symptoms, Perceived Social Support, and Alcohol Use among HIV-Infected Men Who Inject Drugs in Northern Vietnam
Background: Limited research examines depressive symptoms, alcohol use, and social support among HIV-infected people who inject drugs. Objectives: Using longitudinal data, we investigated whether perceived social support moderates the relationship between depressive symptoms and alcohol use among HIV-infected men who inject drugs in Vietnam. Methods: Data were collected from participants (N = 455; mean age 35 years) in a four-arm randomized contr…
Syringe Service Program Utilization, Barriers, and Preferences for Design in Rural Appalachia
Background People who inject drugs (PWID) in rural areas of the United States have had limited access to syringe service programs (SSP). Rural SSP have recently surged, but accompanying research is lacking about PWID utilization, barriers, and preferences for SSP design and how those preferences vary by gender. Methods: Interviewer-administered surveys elicited information about utilization, barriers, and preferences for SSP design from 234 PWID …
“I Was Raised in Addiction”
The aim of this article is to address how conceptualizations of addiction shape the lived experiences of people who use drugs (PWUDs) during the current opioid epidemic. Using a discourse analytic approach, we examine interview transcripts from 27 PWUDs in rural Appalachian Ohio. We investigate the ways in which participants talk about their substance use, what these linguistic choices reveal about their conceptions of self and other PWUDs, and h…

The association between substance use and sub-optimal HIV treatment engagement among HIV-infected female sex workers in Lilongwe, Malawi
Female sex workers (FSW) have a high prevalence of substance use and HIV, but the impact of substance use on HIV treatment engagement is not well established. We evaluated the association between alcohol and marijuana use and sub-optimal HIV treatment engagement outcomes among HIV-infected FSW in Lilongwe, Malawi. We enroled FSW using venue-based recruitment into a cross-sectional evaluation assessing substance use and HIV treatment engagement. S…

On the road again
Long-distance truck drivers have been shown to be a critical population in the spread of HIV in Africa. In 2009, surveys with 385 Ugandan long-distance truck drivers measured concurrency point prevalence with two methods; it ranged from 37.4% (calendar-method) to 50.1% (direct question). The majority (84%) of relationships reported were long-term resulting in a long duration of overlap (average of 58 months) across concurrent partnerships. Only 7…
