Estimating Causal Effects of HIV Prevention Interventions with Interference in Network-based Studies among People Who Inject Drugs.

Evaluating causal effects in the presence of interference is challenging in network-based studies of hard-to-reach populations. Like many such populations, people who inject drugs (PWID) are embedded in social networks and often exert influence on others in their network. In our setting, the study design is observational with a non-randomized network-based HIV prevention intervention. Information is available on each participant and their connections that confer possible HIV risk through injection and sexual behaviors. We considered two inverse probability weighted (IPW) estimators to quantify the population-level spillover effects of non-randomized interventions on subsequent health outcomes. We demonstrated that these two IPW estimators are consistent, asymptotically normal, and derived a closed-form estimator for the asymptotic variance, while allowing for overlapping interference sets (groups of individuals in which the interference is assumed possible). A simulation study was conducted to evaluate the finite-sample performance of the estimators. We analyzed data from the Transmission Reduction Intervention Project, which ascertained a network of PWID and their contacts in Athens, Greece, from 2013 to 2015. We evaluated the effects of community alerts on subsequent HIV risk behavior in this observed network, where the connections or links between participants were defined by using substances or having unprotected sex together. In the study, community alerts were distributed to inform people of recent HIV infections among individuals in close proximity in the observed network. The estimates of the risk differences for spillover using either IPW estimator demonstrated a protective effect. The results suggest that HIV risk behavior could be mitigated by exposure to a community alert when an increased risk of HIV is detected in the network.

The impact of border crossing and imprisonment on injection practices and risk of HIV and hepatitis C infection among men who inject drugs in Nepal.

In Nepal, personal drug use is criminalized and among people who inject drugs (PWID), the majority of whom are men, movement across the border with India for drug procurement and use is common. Using a risk environment approach, this study examined associations between border crossing and imprisonment with respect to HIV, HCV and injection risk behavior among men who inject drugs in Nepal. This cross-sectional study analyzed data from 1345 participants from 14 districts across Nepal. Explanatory variables were prior imprisonment and past-month border crossing to procure or use drugs. We used multivariable logistic regression to evaluate associations between these variables and HIV, HCV, HIV/HCV co-infection and past-month injection risk behavior among PWID. Over half of participants reported prior imprisonment (34.6% prior to past year, 21.6% within past year) and Indo-Nepal border crossing in the past year to use or buy drugs (31.2% sometimes, 20.8% often); over one quarter of participants (29.6%) reported both. Imprisonment prior to the past year was associated with higher odds of all outcome variables: HIV (adjusted odds ratio (aOR) 2.44, 95% confidence interval (CI) 1.29-4.59), HCV (aOR 1.51, 95% CI 1.08-2.09), HIV/HCV co-infection (aOR 3.12, 95% CI 1.58-6.14) and injection risk behavior (aOR 1.64, 95% CI 1.20-2.25). Past-year border crossing to procure or use drugs was associated with HCV (aOR 2.06, 95% CI 1.42-2.98) and injection risk behavior (aOR 1.47, 95% CI 1.04-2.10), with larger effect sizes among PWID who reported both border crossing as well as history of imprisonment. Imprisonment and border crossing were associated with injection risk behavior and disease outcomes. These findings indicate a need to implement cross-border disease surveillance and harm reduction initiatives in the Indo-Nepal border region and in Nepali prisons.

PrEP uptake and early persistence among adolescent girls and young women receiving services via community and hybrid community-clinic models in Namibia.

Adolescent girls and young women (AGYW) face barriers in accessing clinic-based HIV pre-exposure prophylaxis (PrEP) services and community-based models are a proposed alternative. Evidence from such models, however, is limited. We evaluated PrEP service coverage, uptake, and early persistence among AGYW receiving services through community and hybrid models in Namibia. We analyzed routine data for AGYW aged 15-24 who initiated PrEP within HIV prevention programming. PrEP was delivered via three models: community-concierge (fully community-based services with individually-tailored refill locations), community-fixed (community-based initiation and refills delivered by community providers on a set schedule at fixed sites), and hybrid community-clinic (community-based initiation and referral to clinics for refills delivered by clinic providers). We examined proportions of AGYW engaged in services along a programmatic PrEP cascade, overall and by model, and assessed factors associated with PrEP uptake and early persistence (refill within 15-44 days after initiation) using multivariable generalized estimating equations. Over 10-months, 7593 AGYW participated in HIV prevention programming. Of these, 7516 (99.0%) received PrEP education, 6105 (81.2%) received HIV testing services, 6035 (98.9%) tested HIV-negative, and 2225 (36.9%) initiated PrEP. Of the 2047 AGYW expected for PrEP refill during the study period, 254 (12.4%) persisted with PrEP one-month after initiation. Structural and behavioral HIV risk factors including early school dropout, food insecurity, inconsistent condom use, and transactional sex were associated with PrEP uptake. AGYW who delayed starting PrEP were 2.89 times more likely to persist (95% confidence interval (CI): 1.52-5.46) and those receiving services via the community-concierge model were 8.7 times (95% CI: 5.44-13.9) more likely to persist (compared to the hybrid model). Community-based models of PrEP service delivery to AGYW can achieve high PrEP education and HIV testing coverage and moderate PrEP uptake. AGYW-centered approaches to delivering PrEP refills can promote higher persistence.

HIV Syndemic Factor Associations Among Adolescent Gay and Bisexual Men in the Youth Risk Behavior Survey 2015-2019: A Secondary Data Analysis.

This analysis of the Youth Risk Behavior Survey examined HIV syndemic factor associations (substance use, violence, mental health, and HIV risk behaviors) among adolescent gay, bisexual, and other men who have sex with men-a population with the highest prevalence of undiagnosed HIV infections. The representative sample ( n = 644) exhibited low condom use (52%) and HIV testing (21%). Adjusted multivariate logistic regression models showed that Blacks were less likely to report HIV testing (adjusted odds ratio [aOR] = 0.06, 95% confidence interval [CI] [0.01-0.44], p < .01), whereas Hispanics were more likely to report four or more lifetime sexual partners (aOR = 3.75, 95% CI [1.49-9.44], p < .01), compared with Whites. A syndemic of substance use and intimate partner violence (sexual, sexual dating, and/or physical dating violence) was associated with early intercourse, multiple sexual partners, and drugs/alcohol before intercourse. Multiple syndemic factor exposures were associated with additive risk, suggesting multilevel approaches for HIV prevention.

Characterizing Drug use Typologies and Their Association with Sexual Risk Behaviors: A Latent Class Analysis Among Men who have Sex with Men in Mexico

Abstract Introduction Drug use behaviors are closely associated with increased risk for HIV and other STIs among men who have sex with men (MSM) globally. Less is known about the drug use characteristics and their association with HIV/STI risk among MSM in Mexico, who have 13 times higher risk of acquiring HIV than the general population. We characterized distinct classes of drug use behaviors among a nationwide sample of MSM in Mexico and tested their associations with HIV risk behaviors. Methods We used latent class analysis (LCA) to analyze injection/non-injection drug use data collected by the online Encuesta de Sexo Entre Hombres self-administered survey among 15,875 MSM living in Mexico between May-June 2017. MSM were recruited on general social media sites (e.g. Facebook and Twitter), popular LGBT + focused web pages (e.g. Soy Homosensual and Desastre), and dating apps (e.g. Grindr and Hornet). We used robust Poisson regression to examine associations between drug use classes and recent sexual risk behaviors while adjusting for sociodemographic characteristics. Results Most participants were under 30 years of age (65.5%), received a Bachelor’s degree or higher (65.2%), gay-identified (82.5%), HIV negative (58.1%), and lived in the Mexico City/State of Mexico region (34.5%). We identified five distinct drug use classes: Limited Drug Use (75.4%), Marijuana Only (15.1%), Sex Event Popper + Marijuana (4.3%), Club Drug + Marijuana (4.2%), and Elevated Polydrug Use (1.0%). Compared to the Limited Drug Use class, participants in all other drug use classes were significantly more likely to engage in condomless anal intercourse (aPR = 1.14–1.39; p &lt; 0.001), sex exchange (aPR = 1.37–4.99; p &lt; 0.001), anonymous sex (aPR = 1.22–2.01; p &lt; 0.001), group sex (aPR = 1.50–3.28; p &lt; 0.001), and report an STI diagnosis in the past 12 months (aPR = 1.24–2.20; p &lt; 0.002). Estimates were largest among the Elevated Polydrug Use class. Conclusions This study is the first to characterize drug use behaviors and HIV/STI risk among a national sample of MSM in Mexico. Understanding how distinct combinations of drug use behaviors impact sexual risk and prevention behaviors among MSM can inform how best to target and tailor future interventions to reduce HIV/STI incidence.

Utilising the ADAPT-ITT Method to Adapt an Evidence-based Intervention Addressing HIV, Trauma and Mental Health Risks among Female Fish Traders in Zambia

Abstract HIV interventions that attend to mental health problems among vulnerable populations in sub-Saharan Africa have become a priority. This is especially so among mobile populations, such as female fish traders in Zambia, who are at increased risk of trauma, subsequent adverse mental health risks including post-traumatic stress and HIV risk or transmission risk behaviours. To date, there have been no known integrated HIV and mental health interventions among mobile populations in Zambia. Furthermore, although the adaptation of evidence-based interventions to address intersecting risks in non-western contexts has been growing, there is a gap in rigorous adaptation research methods that rely upon the target population for collaborative contextual input. This article aims to describe the application of the ADAPT-ITT (Assessment, Decisions, Administration, Production, Topical experts, Integration, Training staff and Testing) method to adapt an evidence-based intervention (Living in the Face of Trauma) to address intersecting HIV, trauma and mental health risks among female fish traders in Zambia. More specifically, we describe the collaborative and iterative process used and highlight the unique role of social workers throughout this process. Results from the ADAPT-ITT method show promise for the adapted intervention, In Solidarity: Emotional-Coping, Problem-Solving and Entrepreneurship.

A mixed methods exploration of injection drug use risk behaviors and place-based norms in Ukraine

IntroductionDespite global reductions in HIV incidence and significant investment in local harm reduction services, Ukraine continues to experience high HIV and HCV prevalence among people who inject drugs (PWID). Place-based factors and social norms affect drug use–related risk factors, but research has paid little attention to the relationship between drug use practices and place in Ukraine, including how these factors may contribute to or protect against HIV/HCV risk. MethodsThis project used a sequential mixed methods design. Between March and August 2018, we interviewed 30 PWID in Dnipro, Ukraine. Participants completed a single in-depth interview in which they described where and with whom they lived; how they generated income; and where, when, how, and with whom they purchased and used drugs. Between May 2019 and March 2020, we recruited 150 PWID in Dnipro to complete a survey that was designed based on interview findings and consisted of three components: an activity space inventory, an egocentric social network inventory, and an HIV risk behavior assessment. ResultsBoth interview and survey respondents reported consistent use of pharmacies to acquire syringes and nearly universal use of new syringes when injecting. Interview participants reflected that while syringe sharing was previously considered a “common practice,” PWID now viewed it as infrequent and unacceptable. However, interview respondents enumerated the contexts in which needle and syringe reuse occurred, including purchasing drugs directly from a dealer and chipping in with other PWID to prepare drugs bought through a stash. ConclusionParticipants described relatively easy access to new needles and syringes through pharmacies and expressed strong social sanctioning against reusing needles or syringes. However, equipment sharing behaviors and norms persisted in certain contexts, creating an opportunity for further harm reduction campaigns that incorporate changing norms in these situations to “close the gap” and further reduce HIV and other infections among PWID.

Prevalence of HIV among inmates in four states of north India: findings from the 16th round of HIV sentinel surveillance

PurposePrisoners are at a higher risk of HIV infection compared to the general population. The purpose of this study is to estimate the prevalence of HIV and related risk behaviours among inmates of the Central Prisons in four states of North India.Design/methodology/approachThe HIV sentinel surveillance was conducted in seven Central Prisons in four states of North India from February to April 2019. Four hundred inmates were included from each prison. The interviews were conducted at the Integrated Counselling and Testing Centre located within the prison premises. The Ethics Committee of the National AIDS Control Organization, New Delhi, granted ethical approval before the start of the surveillance.FindingsOverall, 2,721 inmates were enrolled in this study. The mean (SD) age was 38.9 (13.9) years. One-third of prison inmates had comprehensive knowledge about HIV/AIDS. The proportion of convict (54%) and undertrial (46%) inmates was almost equal. The overall prevalence of HIV infection among inmates was 0.96% (95% CI 0.65–1.40). The odds of being HIV positive were significantly higher in never married inmates, undertrials, inmates who were in the prison for more than three months to one year, inmates incarcerated for multiple times, inmates with history of injecting drug use and inmates with history of intercourse with a commercial sex worker.Originality/valueThe findings from the very first HIV sentinel surveillance in central prisons in North India have been presented in this paper. This has huge implications for future policy decisions.

Protective factors for adolescent sexual risk behaviours and experiences linked to HIV infection in South Africa: a three-wave longitudinal analysis of caregiving, education, food security, and social protection

BackgroundStructural interventions are endorsed to enhance biomedical and behavioural HIV prevention programmes for adolescents. Aiming to inform future interventions, we evaluated longitudinal associations between six protective factors that link closely to existing structural HIV prevention interventions, and five sexual risk behaviours for HIV transmission in a cohort of adolescents in South Africa.MethodsWe used three rounds of data between 2014–2018 on 1046 adolescents living with HIV and 473 age-matched community peers in South Africa’s Eastern Cape (Observations = 4402). We estimated sex-specific associations between six time-varying protective factors − number of social grants, education enrolment, days with enough food, caregiver supervision, positive caregiving, and adolescent-caregiver communication; and five HIV risk behaviours − multiple sexual partners, transactional sex, age-disparate sex, condomless sex, and sex on substances. HIV risk behaviours were analysed separately in multivariable random effects within-between logistic regression models that accounted for correlation of repeated observations on the same individual. We calculated prevalence ratios (PR), contrasting adjusted probabilities of HIV risk behaviours at ‘No’ and ‘Yes’ for education enrolment, and average and maximum values for the other five protective factors.ResultsThe sample mean age was 15.29 (SD: 3.23) years and 58% were girls. Among girls, within-individuals, increases from mean to maximum scores in positive caregiving were associated with lower probability of transactional sex (PR = 0.79; 95%CI = 0.67–0.91); in caregiver supervision were associated with lower probability of transactional sex (PR = 0.75; 95%CI = 0.66–0.84), and age-disparate sex (PR = 0.84; 95%CI = 0.73–0.95); in adolescent-caregiver communication were associated with higher probability of transactional sex (PR = 1.70; 95%CI = 1.08–2.32); and in days with enough food at home were associated with lower probability of multiple sexual partners (PR = 0.89; 95%CI = 0.81–0.97), and transactional sex (PR = 0.82; 95%CI = 0.72–0.92). Change from non-enrolment in education to enrolment was associated with lower probability of age-disparate sex (PR = 0.49; 95%CI = 0.26–0.73). Between-individuals, relative to mean caregiver supervision scores, maximum scores were associated with lower probability of multiple sexual partners (PR = 0.59; 95%CI = 0.46–0.72), condomless sex (PR = 0.80; 95%CI = 0.69–0.91), and sex on substances (PR = 0.42; 95%CI = 0.26–0.59); and relative to non-enrolment, education enrolment was associated with lower probability of condomless sex (PR = 0.59; 95%CI = 0.39–0.78). Among boys, within-individuals, increases from mean to maximum scores in positive caregiving were associated with lower probability of transactional sex (PR = 0.77; 95%CI = 0.59–0.96), and higher probability of condomless sex (PR = 1.26; 95%CI = 1.08–1.43); in caregiver supervision were associated with lower probability of multiple sexual partners (PR = 0.73; 95%CI = 0.64–0.82), transactional sex (PR = 0.63; 95%CI = 0.50–0.76), age-disparate sex (PR = 0.67; 95%CI = 0.49–0.85), and sex on substances (PR = 0.61; 95%CI = 0.45–0.78), and in days with enough food at home were associated with lower probability of transactional sex (PR = 0.91; 95%CI = 0.84–0.98).ConclusionEffective structural interventions to improve food security and education enrolment among adolescent girls, and positive and supervisory caregiving among adolescent girls and boys are likely to translate into crucial reductions in sexual risk behaviours linked to HIV transmission in this population.

Social and environmental determinants influencing injection drug use and HIV risk among two sister cities on the US–Mexico border: a comparative cross-sectional study, 2016–2018

The economic, social, cultural and political milieus that influence injection drug-related HIV risk behaviors along the US–Mexico border in the previous decade have been studied comparing cities on an East–West axis. In an effort to inform interventions targeting factors beyond the individual level, we used a cross-sectional study design comparing people who inject drugs during 2016–2018, living on a North–South axis, in two cities—Ciudad Juárez, Chihuahua, Mexico and El Paso, Texas, USA—situated at the midpoint of the 2000 US–Mexico borderland stretch. We conceptualize injection drug use and its antecedents and consequences as influenced by factors operating at various levels of influence. Results of analysis comparing samples recruited from each border city indicated significant differences in demographic, socioeconomic, micro- and macro-level factors that affect risk. Similarities emerged in individual-level risk behaviors and some dynamics of risk at the drug use site most frequented to use drugs. In addition, analyses testing associations across samples indicated that different contextual factors such as characteristics of the drug use sites influenced syringe sharing. In this article, we reflect on the potential tailored interventions needed to target the context of HIV transmission risk among people who use drugs and reside in binational environment.

Novel Location-Based Survey Using Cognitive Interviews to Assess Geographic Networks and Hotspots of Sex and Drug Use: Implementation and Validation Study.

The Ending the HIV Epidemic initiative in the United States relies on HIV hotspots to identify where to geographically target new resources, expertise, and technology. However, interventions targeted at places with high HIV transmission and infection risk, not just places with high HIV incidence, may be more effective at reducing HIV incidence and achieving health equity. We described the implementation and validation of a web-based activity space survey on HIV risk behaviors. The survey was intended to collect geographic information that will be used to map risk behavior hotspots as well as the geography of sexual networks in Los Angeles County. The survey design team developed a series of geospatial questions that follow a 3-level structure that becomes more geographically precise as participants move through the levels. The survey was validated through 9 cognitive interviews and iteratively updated based on participant feedback until the saturation of topics and technical issues was reached. In total, 4 themes were identified through the cognitive interviews: functionality of geospatial questions, representation and accessibility, privacy, and length and understanding of the survey. The ease of use for the geospatial questions was critical as many participants were not familiar with mapping software. The inclusion of well-known places, landmarks, and road networks was critical for ease of use. The addition of a Google Maps interface, which was familiar to many participants, aided in collecting accurate and precise location information. The geospatial questions increased the length of the survey and warranted the inclusion of features to simplify it and speed it up. Using nicknames to refer to previously entered geographic locations limited the number of geospatial questions that appeared in the survey and reduced the time taken to complete it. The long-standing relationship between participants and the research team improved comfort to disclose sensitive geographic information related to drug use and sex. Participants in the cognitive interviews highlighted how trust and inclusive and validating language in the survey alleviated concerns related to privacy and representation. This study provides promising results regarding the feasibility of using a web-based mapping survey to collect sensitive location information relevant to ending the HIV epidemic. Data collection at several geographic levels will allow for insights into spatial recall of behaviors as well as future sensitivity analysis of the spatial scale of hotspots and network characteristics. This design also promotes the privacy and comfort of participants who provide location information for sensitive topics. Key considerations for implementing this type of survey include trust from participants, community partners, or research teams to overcome concerns related to privacy and comfort. The implementation of similar surveys should consider local characteristics and knowledge when crafting the geospatial components.

Uptake and perceptions of oral HIV self-testing delivered by village health teams among men in Central Uganda: A concurrent parallel mixed methods analysis.

The World Health Organization (WHO) recommends HIV self-testing (HIVST) to increase access to and utilization of HIV services among underserved populations. We assessed the uptake and perceptions of oral HIVST delivered by Village Health Teams (VHTs) among men in a peri-urban district in Central Uganda. We used a concurrent parallel mixed methods study design and analyzed data from 1628 men enrolled in a prospective cohort in Mpigi district, Central Uganda between October 2018 and June 2019. VHTs distributed HIVST kits and linkage-to-care information leaflets to participants in 30 study villages allowing up-to 10 days each to self-test. At baseline, we collected data on participant socio-demographics, testing history and risk behavior for HIV. During follow-up, we measured HIVST uptake (using self-reports and proof of a used kit) and conducted in-depth interviews to explore participants' perceptions of using HIVST. We used descriptive statistics to analyze the quantitative data and a hybrid inductive, and deductive thematic analysis for the qualitative data and integrated the results at interpretation. The median age of men was 28 years, HIVST uptake was 96% (1564/1628), HIV positivity yield was 4% (63/1564) and reported disclosure of HIVST results to sexual partners and significant others was 75.6% (1183/1564). Men perceived HIVST as a quick, flexible, convenient, and more private form of testing; allowing disclosure of HIV test results to sexual partners, friends and family, and receiving social support. Others perceived it as an opportunity for knowing or re-confirming their sero-status and subsequent linkage or re-linkage to care and prevention. Utilizing VHT networks for community-based delivery of HIVST is effective in reaching men with HIV testing services. Men perceived HIVST as highly beneficial but needed more training on performing the test and the integrating post-test counseling support to optimize use of the test for diagnosing HIV.

HIV prevalence, risk behaviour, and treatment and prevention cascade outcomes among cisgender men, transgender women, and transgender men who sell sex in Zimbabwe: a cross-sectional analysis of programme data

There is a paucity of evidence on HIV vulnerabilities and service engagements among people who sell sex in sub-Saharan Africa and identify as cisgender men, transgender women, or transgender men. We aimed to describe sexual risk behaviours, HIV prevalence, and access to HIV services among cisgender men, transgender women, and transgender men who sell sex in Zimbabwe. We did a cross-sectional analysis of routine programme data that were collected between July 1, 2018, and June 30, 2020, from cisgender men who sell sex, transgender women who sell sex, and transgender men who sell sex, as part of accessing sexual and reproductive health and HIV services provided through the Sisters with a Voice programme, at 31 sites across Zimbabwe. All people who sell sex reached by the programme had routine data collected, including routine HIV testing, and were referred using a network of peer educators. Sexual risk behaviours, HIV prevalence, and HIV services uptake during the period from July, 2018, to June, 2020, were analysed through descriptive statistics by gender group. A total of 1003 people who sell sex were included in our analysis: 423 (42·2%) cisgender men, 343 (34·2%) transgender women, and 237 (23·6%) transgender men. Age-standardised HIV prevalence estimates were 26·2% (95% CI 22·0-30·7) among cisgender men, 39·4% (34·1-44·9) among transgender women, and 38·4% (32·1-45·0) among transgender men. Among people living with HIV, 66·0% (95% CI 55·7-75·3) of cisgender men, 74·8% (65·8-82·4) of transgender women, and 70·2% (59·3-79·7) of transgender men knew their HIV status, and 15·5% (8·9-24·2), 15·7% (9·5-23·6), and 11·9% (5·9-20·8) were on antiretroviral therapy, respectively. Self-reported condom use was consistently low across gender groups, ranging from 26% (95% CI 22-32) for anal sex among transgender women to 32% (27-37) for vaginal sex among cisgender men. These unique data show that people who sell sex and identify as cisgender men, transgender women, or transgender men in sub-Saharan Africa have high HIV prevalences and risk of infection, with alarmingly low access to HIV prevention, testing, and treatment services. There is an urgent need for people-centred HIV interventions for these high-risk groups and for more inclusive HIV policies and research to ensure we truly attain universal access for all.

Prevalence of HIV, risk behaviours and vulnerabilities of female sex partners of the HIV positive people who inject drugs (PWID) in Dhaka city, Bangladesh.

The HIV epidemic in Bangladesh is largely being driven by people who inject drugs (PWID) and mainly concentrated in Dhaka city. Intregrated biological and behavioural survey (IBBS) data of 2016 showed that a considerable percentage of the HIV positive PWID had unsafe sex with their female sex partners. Prevalence of HIV, risk behaviorus and vulnerabilities among the female sex partners of the PWID still remain unexplored. To measure HIV prevalence, risk behaviours (drugs/injection/sexual) and vulnerabilities (treatment of and knowledge of sexually transmitted infections (STIs) and HIV/uptake of the routine HIV testing and HIV prevention services/physical and sexual violence), a quantitative survey was conducted among 227 female sex partners of the HIV positive PWID in Dhaka city in 2019 by adopting a take-all sampling technique. The median age of participants was 34.0 years. Prevalence of HIV was 16.7% (95% CI: 12.4-22.2). Only 6.8% to 18.7% of the participants used condoms consistently with different male sex partners; only 6.8%cto 18.7% during last year. Seventy five percent (95% CI: 69.2-80.8) had no knowledge on STI symptoms. Self-reported symptoms of STIs were reported by 26% (95% CI: 20.7-32.1) and half sought treatment during last year. Nineteen percent (95% CI: 14.7-25.1) had comprehensive knowledge of HIV. As part of the routine HIV prevention services by the PWID drop-in-centres (DICs), 42.7% (95% CI: 36.4-49.3) of the participants were tested for HIV and knew their result within the last year. One-third never received HIV prevention services. During the last one year preceding the survey, 46% (95% CI: 39.3-52.6) reported been beaten and 20.2% (95% CI: 15.3-26.1) been raped. It is urgently necessary to consider the high-risk behaviours and vulnerabilities in designing or to strengthen targeted interventions for female sex partners of the HIV positive PWID in Dhaka city to ensure equality in accessing and utilization of services.

EPH86 Associations between Depression and HIV Testing / Risk Behaviors in the United States

The objective of the study was to assess differences in HIV testing and HIV risk behaviors by depression status among a nationally representative sample of U.S. adults.

Adverse childhood experiences and human immunodeficiency virus testing among adults with human immunodeficiency virus risk behaviours.

Adverse childhood experiences (ACEs) have been associated with poor HIV testing in adulthood yet, they have not been extensively described in those at increased risk for HIV. Cross-sectional analysis data (n=204,231) on ACEs and HIV testing were obtained from the 2019-2020 Behavioural Risk Factor Surveillance Survey. Weighted logistic regression models were used to access the association of ACEs exposure, ACEs score, and ACEs type with HIV testing among adults with HIV risk behaviours, and stratified analysis was also performed to examine gender differences. The results indicated the overall rate of HIV testing was 38.8% and was higher among those with HIV risk behaviours (64.6%) than those without (37.2%). In populations with HIV risk behaviours, the negative association of HIV testing with ACEs exposure, ACEs score, and ACEs type was identified. Relative to those without ACEs, adults who were exposed to ACEs might decrease the rate of HIV testing, participants with ≥4 ACEs scores were less likely to have HIV testing, and childhood exposure to sexual abuse had the greatest impact on HIV testing. For both males and females, childhood exposure to ACEs was associated with lower odds of HIV testing and ACEs score ≥4 had the most robust associations with HIV testing. For males, those who experienced witnessed domestic violence had the lowest odds of HIV testing but the odds of engaging in HIV testing for females were the lowest among those who experienced childhood sexual abuse.

HIV testing and risk behaviors associated with depression in the United States

Given the high correlation between depression and HIV infection rates, our objective was to assess national rates for HIV testing and HIV risk behaviors among U.S. adults stratified by self-reports of depression. We conducted a cross-sectional study using data from the 2018–2020 Behavioral Risk Factor Surveillance System (BRFSS). We included respondents aged 18 years old and above with self-reported depression status (Sample size = 1,228,405). The primary outcomes included HIV testing and HIV-related risk behaviors. For respondents with prior HIV testing experience, we estimated the duration since the last HIV test. We applied a multivariable logistic regression model to analyze the correlation between depression and HIV testing or risk behaviors. The results showed people with depression had 51% higher odds of receiving HIV testing [adjusted odds ratio (AOR) = 1.51, 95% CI = 1.48, 1.55] and 51% higher odds of involvement in HIV risk behaviors [AOR = 1.51, 95% CI = 1.44, 1.58] after adjusting for covariates. Various socio-demographics and healthcare access variables were significantly associated with HIV testing and HIV risk behaviors. When comparing the average time from the last HIV test, people with depression had a shorter period compared to those without depression [Median time in months: 27.1 ± 0.45 vs. 29.3 ± 0.34]. Even though people with depression had higher rates of HIV testing, they still experienced long time periods (median = 2 + years) between HIV testing, which exceeded the recommended annual HIV testing for people at high risk from the Centers for Disease Control and Prevention.

Access to healthcare among sexual and gender minority youth at risk for HIV: barriers and experiences of discrimination

ABSTRACT This study examined experiences of healthcare inaccessibility and lesbian, gay, bisexual, transgender, queer, plus (LGBTQ+) discrimination among sexual and gender minority youth at elevated risk for HIV in the United States. Participants for this cross-sectional survey study (N = 3330) were cisgender men, transgender men and women, and nonbinary individuals ages 18–34 recruited for a larger study examining HIV risk behavior between December 2017 and December 2019. Results indicated that 41.1% of participants had at least one lifetime experience of LGBTQ + healthcare discrimination, and 44.1% reported past 6-month experiences of discrimination or problems accessing healthcare. Transgender men and women were more likely than cisgender men and nonbinary participants to report experiences of discrimination, and transgender men were more likely to report problems accessing healthcare. A majority of participants (72.8%) reported that their most recent healthcare provider was aware of their sexual or gender identity. These results indicate a high prevalence of structural barriers in healthcare access for sexual and gender minority youth at elevated risk for HIV, including finical and logistical barriers as well as anticipated and experienced discrimination. We discuss these findings and highlight the importance of easily accessible and culturally competent care for this community.

Association of gender-based violence with sexual and drug-related HIV risk among female sex workers who use drugs in Kazakhstan.

Little is known about the prevalence of intimate partner violence (IPV) or client violence, and associated HIV risk among women who engage in sex work (WESW) and use drugs in Kazakhstan, despite a growing HIV epidemic. Women who reported engaging in sex work and using illicit drugs were recruited from Almaty and Temirtau, Kazakhstan between 2015 and 2017. A cross-sectional analysis was conducted to determine prevalence and correlates of physical and sexual violence perpetrated by intimate partners and clients. Associations between each type of violence with sexual and drug-related HIV risk behaviors were assessed with negative-binomial and logistic regression models, respectively. Of the 400 women, 45% and 28% reported recent IPV and client violence, respectively. IPV and client violence was associated with a greater number of sex work clients [IPV: adjusted incidence rate ratio (aIRR)physical: 1.86, 1.28-2.71; aIRRsexual: 2.28, 1.56-3.35]; [client violence: aIRRphysical: 2.20, 1.44-3.42; aIRRsexual: 2.54, 1.72-3.83], and client violence was associated with greater frequency of condomless sex with clients [aIRRphysical: 2.33, 1.41-4.03; aIRRsexual: 2.16, 1.35-3.56]. Violence was not associated with injection drug use, despite exchanging sex for drugs being associated with higher odds of violence. HIV prevention programs for WESW in Kazakhstan should consider multi-sectoral approaches that address economic hardship and relationship-based components, in addition to violence reduction.

Spatio-temporal estimates of HIV risk group proportions for adolescent girls and young women across 13 priority countries in sub-Saharan Africa.

The Global AIDS Strategy 2021-2026 identifies adolescent girls and young women (AGYW) as a priority population for HIV prevention, and recommends differentiating intervention portfolios geographically based on local HIV incidence and individual risk behaviours. We estimated prevalence of HIV risk behaviours and associated HIV incidence at health district level among AGYW living in 13 countries in sub-Saharan Africa. We analysed 46 geospatially-referenced national household surveys conducted between 1999-2018 across 13 high HIV burden countries in sub-Saharan Africa. Female survey respondents aged 15-29 years were classified into four risk groups (not sexually active, cohabiting, non-regular or multiple partner[s] and female sex workers [FSW]) based on reported sexual behaviour. We used a Bayesian spatio-temporal multinomial regression model to estimate the proportion of AGYW in each risk group stratified by district, year, and five-year age group. Using subnational estimates of HIV prevalence and incidence produced by countries with support from UNAIDS, we estimated new HIV infections in each risk group by district and age group. We then assessed the efficiency of prioritising interventions according to risk group. Data consisted of 274,970 female survey respondents aged 15-29. Among women aged 20-29, cohabiting (63.1%) was more common in eastern Africa than non-regular or multiple partner(s) (21.3%), while in southern countries non-regular or multiple partner(s) (58.9%) were more common than cohabiting (23.4%). Risk group proportions varied substantially across age groups (65.9% of total variation explained), countries (20.9%), and between districts within each country (11.3%), but changed little over time (0.9%). Prioritisation based on behavioural risk, in combination with location- and age-based prioritisation, reduced the proportion of population required to be reached in order to find half of all expected new infections from 19.4% to 10.6%. FSW were 1.3% of the population but 10.6% of all expected new infections. Our risk group estimates provide data for HIV programmes to set targets and implement differentiated prevention strategies outlined in the Global AIDS Strategy. Successfully implementing this approach would result in more efficiently reaching substantially more of those at risk for infections.
