Integrated biobehavioral surveillance among people who inject drugs in Ukraine, 2007-2020.

Background: Repeated integrated biobehavioral surveys (IBBS) have been implemented among people who inject drugs (PWID) in Ukraine to monitor the trends in key epidemiologic and programmatic indicators.

Methods: The study analyzed seven PWID IBBS rounds from 2007 to 2020 in seven Ukrainian cities. Participants were recruited using respondent-driven sampling, tested for HIV and anti-HCV antibodies, and completed a structured questionnaire.

Community-based HIV prevention services for transgender people in Ukraine: current situation and potential for improvement.

Background: Community-based HIV-prevention services are a key approach to prevent HIV transmission among key population representatives. Transgender people have multiple specific needs and it is crucial to use prevention approaches that effectively respond to those needs and facilitate barriers on the way to use HIV prevention and related services. This study is aimed to explore the current state of community-based HIV prevention services among transgender people in Ukraine, its limitations and potential for improvement based on the experience and perceptions of transgender people, physicians, and community social workers providing services to transgender people.

Modelling the impact and cost-effectiveness of non-governmental organizations on HIV and HCV transmission among people who inject drugs in Ukraine.

Introduction: People who inject drugs (PWID) in Ukraine have high prevalences of HIV and hepatitis C virus (HCV). Non-governmental organizations (NGOs) provide PWID with needles/syringes, condoms, HIV/HCV testing and linkage to opioid agonist treatment (OAT) and antiretroviral therapy (ART). We estimated their impact and cost-effectiveness among PWID.

Impact and cost-effectiveness of non-governmental organizations on the HIV epidemic in Ukraine among MSM.

Objective: Non-governmental organizations (NGOs) in Ukraine have provided HIV testing, treatment, and condom distribution for MSM. HIV prevalence among MSM in Ukraine is 5.6%.

Costs and impact on HIV transmission of a switch from a criminalisation to a public health approach to injecting drug use in eastern Europe and central Asia: a modelling analysis.

Background: HIV incidence is increasing in eastern Europe and central Asia, primarily driven by injecting drug use. Coverage of antiretroviral therapy (ART) and opioid agonist therapy are suboptimal, with many people who inject drugs (PWID) being incarcerated. We aimed to assess whether use of monies saved as a result of decriminalisation of drug use or possession to scale up ART and opioid agonist therapy could control HIV transmission among PWID in eastern Europe and central Asia.

HIV treatment cascade among people who inject drugs in Ukraine.

The HIV treatment cascade is an effective tool to track progress and gaps in the HIV response among key populations. People who inject drugs (PWID) remain the most affected key population in Ukraine with HIV prevalence of 22% in 2015. We performed secondary analysis of the 2017 Integrated Bio-Behavioral Surveillance (IBBS) survey data to construct the HIV treatment cascade for PWID and identify correlates of each indicator achievement.

Is contact between men who have sex with men and non-governmental organizations providing harm reduction associated with improved HIV outcomes?

Objectives: There is a high prevalence of HIV (5.2% in 2018) among men who have sex with men (MSM) in Ukraine. HIV testing, condom provision and facilitated linkage to HIV treatment have been funded by various bodies through non-governmental organizations (NGOs).

Has resourcing of non-governmental harm-reduction organizations in Ukraine improved HIV prevention and treatment outcomes for people who inject drugs? Findings from multiple bio-behavioural surveys.

Introduction: People who inject drugs (PWID) in Ukraine have high prevalences of HIV and hepatitis C (HCV). Since the turn of the century, various organizations have funded non-governmental organizations (NGOs) in Ukraine to provide PWID with needles and syringes, condoms, HIV and HCV testing, and improve linkage to opioid agonist therapy (OAT) and HIV treatment. We investigated whether contact with these NGOs was associated with improved HIV prevention and treatment outcomes among PWID.

Operationalizing the HIV prevention cascade for PWID using the integrated bio-behavioural survey data from Ukraine.

Introduction: People who inject drugs (PWID) remain at high risk of HIV in many countries. The HIV prevention cascades have been proposed to replicate the success of the treatment cascades and reinvigorate the prevention programmes through improved monitoring, planning and delivery. We adapted the cascade framework to the PWID context in Ukraine, assessed gaps and analysed factors associated with achieving "access" and "effective use" outcomes.

Divergent estimates of HIV incidence among people who inject drugs in Ukraine.

Background: Divergent estimates of HIV incidence among people who inject drugs (PWID) in Ukraine have been reported in modeling studies, longitudinal cohort studies, and recent infection assays used in cross-sectional surveys. Estimates range from 0.65 to 24.

HIV testing behaviour and HIV prevalence among female sex workers in Ukraine: findings from an Integrated Bio-Behavioural Survey, 2013-2014.

Objectives: Ukraine has one of the largest HIV epidemics in Europe, with high prevalence among female sex workers (FSWs). We aimed to identify factors associated with HIV testing and receipt of the test result in the last 12 months, HIV prevalence and self-reported positive status among FSWs in Ukraine.

Methods: We used data from an Integrated Bio-Behavioural Survey among FSWs conducted in 2013-2014.

Patterns of harm reduction service utilization and HIV incidence among people who inject drugs in Ukraine: A two-part latent profile analysis.

Background: Program utilization patterns are described within a large network of harm reduction service providers in Ukraine. The relationship between utilization patterns and HIV incidence is determined among people who inject drugs (PWID) controlling for oblast-level HIV incidence and treatment/syringe coverage.

Methods: Data were extracted from the network's monitoring and evaluation database (January 2011-September 2014, n=327,758 clients).

Trends in Injection Risk Behaviors among People Who Inject Drugs and the Impact of Harm Reduction Programs in Ukraine, 2007-2013.

The study examined trends in injection risk behaviors among people who inject drugs (PWIDs) and assessed the impact of harm reduction programs in Ukraine during 2007-2013. We performed a secondary analysis of the data collected in serial cross-sectional bio-behavioral surveillance surveys administered with PWIDs in Ukraine in 2007, 2008, 2011, and 2013. Using data from 14 Ukrainian cities, we assessed short-term trends in injection risk behaviors with the Cochran-Armitage test for trend and multivariable logistic regression models, adjusted for age, sex, region, marital status, education level, occupation, age at injection drug use initiation, experience of overdose, and self-reported HIV status.

Counting hard-to-count populations: the network scale-up method for public health.

Estimating sizes of hidden or hard-to-reach populations is an important problem in public health. For example, estimates of the sizes of populations at highest risk for HIV and AIDS are needed for designing, evaluating and allocating funding for treatment and prevention programmes. A promising approach to size estimation, relatively new to public health, is the network scale-up method (NSUM), involving two steps: estimating the personal network size of the members of a random sample of a total population and, with this information, estimating the number of members of a hidden subpopulation of the total population.

Correlates of HIV risk among injecting drug users in sixteen Ukrainian cities.

We present findings from a HIV survey using respondent driven sampling among 3,711 injecting drug users (IDUs) in 16 cities in Ukraine in 2008. Eligible participants were males and females who injected drugs in the past 1 month, ≥ 16 years and lived/worked in their respective interview area. The impact of injecting and sexual risk behaviors on HIV-infection were analyzed using four logistic models.
