ABSTRACT
BACKGROUND: Adherence to antiretroviral therapy (ART) has individual and public health benefits and is critical to improving life expectancy, achieving viral suppression, and reducing the risk of HIV transmission. This qualitative study explored the experience of receiving care as well as perceived facilitators and barriers of treatment initiation, retention in ART care, and adherence to treatment. METHODS: In-depth interviews were conducted among 28 men who have sex with men (MSM) and female sex workers (FSWs) receiving ART services in Lagos and Benue states. Key informant interviews were also conducted among 16 service providers engaged in counselling, clinical care, and ART treatment for MSM and FSWs. The Social Ecology Model guided the exploration of perceived barriers and facilitators of treatment initiation, retention in ART care and adherence to treatment. Qualitative data analysis was managed using NVIVO 11 software and themes were analysed using thematic analysis. RESULTS: We found that the key barriers to ART adherence were low motivation to comply with medication regimen, work commitments, socioeconomic factors, stigma, negative provider attitude and distance to health facilities. Facilitators of adherence identified include the desire to live a productive life, strong family support and participation in support group programs. Comprehensive adherence counselling, support group programs and an effective follow-up system were factors identified by service providers as key to facilitating adherence. CONCLUSION: To be effective, ART programs must address the unique challenges key populations face in accessing treatment and achieving optimal adherence regarding establishing a strong support system and follow-up. Community level interventions that support a stigma-free environment are critical to sustaining engagement in care.
ABSTRACT
ABSTRACT: Key populations (KPs) experience suboptimal outcomes along the HIV care and prevention continua, but there is limited study of the challenges service providers encounter delivering HIV services to KPs, particularly in settings like Zambia, where provision of these services remains legally ambiguous. Seventy-seven providers completed in-depth interviews exploring constraints to HIV service delivery for KPs and recommendations for improving access and care quality. Thematic analysis identified salient challenges and opportunities to service delivery and quality of care for KPs, spanning interpersonal, institutional, and structural domains. Limited provider training in KP-specific needs was perceived to influence KP disclosure patterns in clinical settings, impeding service quality. The criminalization of KP sexual and drug use behaviors, coupled with perceived institutional and legal ambiguities to providing HIV services to KPs, cultivated unwelcoming service delivery environments for KPs. Findings elucidate opportunities for improving HIV service delivery/quality, from decentralized care to expanded legal protections for KPs and service providers.

BACKGROUND: This study aimed to help the Namibian government understand the impact of Treat All implementation (started on April 1, 2017) on key antiretroviral therapy (ART) outcomes, and how this transition impacts progress toward the UNAIDS's 90-90-90 HIV targets. METHODS: We collected clinical records from two separate cohorts (before and after treat-all) of ART patients in 10 high- and medium-volume facilities in 6 northern Namibia districts. Each cohort contains 12-month data on patients' scheduled appointments and visits, health status, and viral load results. We also measured patients' wait time and perceptions of service quality using exit interviews with 300 randomly selected patients (per round). We compared ART outcomes of the two cohorts: ART initiation within 7 days from diagnosis, loss to follow-up (LTFU), missed scheduled appointments for at least 30 days, and viral suppression using unadjusted and adjusted analyses. RESULTS: Among new ART clients (on ART for less than 3 months or had not yet initiated treatment as of the start date for the ART record review period), rapid ART initiation (within 7 days from diagnosis) was 5.2 times higher after Treat All than that among clients assessed before the policy took effect [AOR: 5.2 (3.8-6.9)]. However, LTFU was higher after Treat All roll-out compared to before Treat All [AOR: 1.9 (1.3-2.8)]. Established ART clients (on ART treatment for at least three months at the start date of the ART record review period) had over 3 times greater odds of achieving viral suppression after Treat All roll-out compared to established ART clients assessed before Treat All [AOR: 3.1 (1.6-5.9)]. CONCLUSIONS AND RECOMMENDATIONS: The findings indicate positive effect of the "Treat All" implementation on ART initiation and viral suppression, and negative effect on LTFU. Additionally, by April 2018, Namibia seems to have reached the UNAIDS's 90-90-90 targets.

OBJECTIVE(S): To describe the process of updating the People Living with HIV (PLHIV) Stigma Index (Stigma Index) to reflect current global treatment guidelines and to better measure intersecting stigmas and resilience. DESIGN: Through an iterative process driven by PLHIV, the Stigma Index was revised, pretested, and formally evaluated in three cross-sectional studies. METHODS: Between March and October 2017, 1153 surveys (nâ=â377, Cameroon; nâ=â390, Senegal; nâ=â391, Uganda) were conducted with PLHIV at least 18 years old who had known their status for at least 1 year. PLHIV interviewers administered the survey on tablet computers or mobile phones to a diverse group of purposively sampled respondents recruited through PLHIV networks, community-based organizations, HIV clinics, and snowball sampling. Sixty respondents participated in cognitive interviews (20 per country) to assess if questions were understood as intended, and eight focus groups (Uganda only) assessed relevance of the survey, overall. RESULTS: The Stigma Index 2.0 performed well and was relevant to PLHIV in all three countries. HIV-related stigma was experienced by more than one-third of respondents, including in HIV care settings. High rates of stigma experienced by key populations (such as MSM and sex workers) impeded access to HIV services. Many PLHIV also demonstrated resilience per the new PLHIV Resilience Scale. CONCLUSION: The Stigma Index 2.0 is now more relevant to the current context of the HIV/AIDS epidemic and response. Results will be critical for addressing gaps in program design and policies that must be overcome to support PLHIV engaging in services, adhering to antiretroviral therapy, being virally suppressed, and leading healthy, stigma-free lives.

OBJECTIVE: Measuring internalized stigma is critical to understanding its impact on the health and quality of life of people living with HIV (PLHIV). The aim of this study was to assess the performance of the Internalized AIDS-Related Stigma Scale (IA-RSS). DESIGN: Secondary analysis of the six-item IA-RSS was conducted using data from four cross-sectional surveys implemented in Cambodia (nâ=â1207), the Dominican Republic (nâ=â891), Uganda (nâ=â391) and Tanzania (nâ=â529) between 2018 and 2019. METHODS: IA-RSS scale item distribution was described. Multivariate regression models measured correlations between the IA-RSS and depression, antiretroviral therapy (ART) use and viral suppression. Confirmatory factor analysis assessed IA-RSS reliability and performance through analysis of standardized factor loadings and conditional probabilities of scale items. Analysis of qualitative interviews with PLHIV explored acceptability of IA-RSS item content. RESULTS: Mean IA-RSS scores (possible 0-6) ranged from 2.06 (Uganda) to 3.84 (Cambodia), and internal consistency was more than 0.70 in each country (Kuder-Richardson 20), ranging from 0.71 to 0.83. Higher IA-RSS scores were strongly correlated with depression in (Pâ<â0.001 in all countries), and inversely associated with current ART use (Dominican Republic and Tanzania) and self-reported viral suppression (Uganda and Tanzania). Confirmatory factor analysis showed good model fit (all CFIâ≥â0.950), but also that the IA-RSS may summarize two domains related to HIV status disclosure (two items) and PLHIV feelings about themselves (four items). CONCLUSION: Strong performance across countries supports continued use of the IA-RSS. Further study is needed to explore potential item refinements and to better understand the relationship between internalized stigma and HIV treatment outcomes.

HIV Self-Testing (HIVST) aims to increase HIV testing coverage and can facilitate reaching the UNAIDS 90-90-90 targets. In Senegal, key populations bear a disproportionate burden of HIV and report limited uptake of HIV testing given pervasive stigma and criminalization. In these contexts, HIVST may represent a complementary approach to reach populations reporting barriers to engagement with existing and routine HIV testing services. In this study, 1839 HIVST kits were distributed in Senegal, with 1149 individuals participating in a pre-test questionnaire and 817 participating in a post-test questionnaire. Overall, 46.9% (536/1144) were first-time testers and 26.2% (300/1144) had tested within the last year; 94.3% (768/814) reported using the HIVST, and 2.9% (19/651) reported a reactive result which was associated with first-time testers (p = 0.024). HIVST represents an approach that reached first-time testers and those who had not tested recently. Implementation indicators suggest the importance of leveraging existing community structures and programs for distribution.

Capacity building in implementation science is integral to PEPFAR's mission and to meeting the 90-90-90 goals. The USAID funded Project SOAR sponsored a 4 day workshop for investigators and governmental and non-governmental partners from 12 African countries. The workshop was designed to address both findings from a pre-workshop online needs assessment as well as capacity challenges across the capacity building pyramid, from individual skills to institutional systems and resources. Activities were output-oriented and skill based. An online survey evaluated sessions and changes in perceptions of needs; a majority of respondents strongly agreed that after the workshop, they better understood their personal and institutional capacity strengthening needs. Participants 'strongly agreed' that workshop content was relevant to their jobs (90%) and that they left the workshop with a specific plan for conducting future research (65%). Workshop results suggest that skill-building should be done in conjunction with systems capacity building within the cultural context.

HIV epidemic control requires improving access and uptake of HIV services by key populations (KPs). In Zambia, the behaviors of female sex workers (FSWs), men who have sex with men (MSM), and people of who use drugs (PWUD) are criminalized, and little information exists about their HIV/STI service use. Using a quality of care (QOC) framework, we compared barriers to and opportunities for HIV/STI service access and uptake among the three KPs. We conducted in-depth interviews and focus group discussions with 314 KP members between July 2013 and September 2015 in eight districts. Poorer QOC was received at public health facilities compared to private, NGOs and traditional healers. Stigma and discrimination, confidentiality, and legal prosecution were barriers to service use and more salient among MSM than FSWs and PWUD. Invasive facility policies were barriers and more prominent among FSWs than MSM and PWUD. Service unavailability was of equally high salience among MSM and PWUD than FSWs. Comfort in the clinic and perceived treatment effectiveness were facilitators for all three KPs. The health care experiences of KPs are not monolithic; HIV/STI service improvement strategies should address the concerns and be tailored to the needs of each key population.

PURPOSE: Working with health providers to reduce HIV stigma in the healthcare setting is an important strategy to improve service utilization and quality of care, especially for young people who are sexually active before marriage, are sexual minorities, or who sell sex. A stigma reduction training program for health providers in Bangladesh was evaluated. METHODS: A cohort of 300 healthcare providers were given a self-administered questionnaire, then attended a 2-day HIV and sexual and reproductive health and rights training (including a 90-minute session on stigma issues). Six months later, the cohort repeated the survey and participated in a 1-day supplemental training on stigma, which included reflection on personal values and negative impacts of stigma. A third survey was administered 6 months later. A cross-sectional survey of clients age 15-24 years was implemented before and after the second stigma training to assess client satisfaction with services. RESULTS: Provider agreement that people living with HIV should be ashamed of themselves decreased substantially (35.3%-19.7%-16.3%; p < .001), as did agreement that sexually active young people (50.3%-36.0%-21.7%; p < .001) and men who have sex with men (49.3%-38.0%-24.0%; p < .001) engage in "immoral behavior." Young clients reported improvement in overall satisfaction with services after the stigma trainings (63.5%-97.6%; p < .001). CONCLUSIONS: This study indicates that a targeted stigma reduction intervention can rapidly improve provider attitudes and increase service satisfaction among young people. More funding to scale up these interventions is needed.

BACKGROUND: Respondent-driven sampling (RDS) is used in a variety of settings to study hard-to-reach populations at risk for HIV and sexually transmitted infections. However, practices leading to successful recruitment among diverse populations in low-resource settings are seldom reported. We implemented the first, integrated, bio-behavioural surveillance survey among men who have sex with men, female sex workers and people who injected drugs in Nairobi, Kenya. METHODS: The survey period was June 2010 to March 2011, with a target sample size of 600 participants per key populations. Formative research was initially conducted to assess feasibility of the survey. Weekly monitoring reports of respondent characteristics and recruitment chain graphs from NetDraw illustrated patterns and helped to fill recruitment gaps. RESULTS: RDS worked well with men who have sex with men and female sex workers with recruitment initiating at a desirable pace that was maintained throughout the survey. Networks of people who injected drugs were well-integrated, but recruitment was slower than the men who have sex with men and female sex workers surveys. CONCLUSION: By closely monitoring RDS implementation and conducting formative research, RDS studies can effectively develop and adapt strategies to improve recruitment and improve adherence to the underlying RDS theory and assumptions.

OBJECTIVE: Evaluate the reliability and validity of the Youth Self-Report (YSR) as a screening tool for mental health problems among young people vulnerable to HIV in Ethiopia. DESIGN: A cross-sectional assessment of young people currently receiving social services. METHODS: Young people age 15-18 participated in a study where a translated and adapted version of the YSR was administered by trained nurses, followed by an assessment by Ethiopian psychiatrists. Internal reliability of YSR syndrome scales were assessed using Chronbach's alpha. Test-retest reliability was assessed through repeating the YSR one month later. To assess validity, analysis of the sensitivity and specificity of the YSR compared to the psychiatrist assessment was conducted. RESULTS: Across the eight syndrome scales, the YSR best measured the diagnosis of anxiety/depression and social problems among young women, and attention problems among young men. Among individual YSR syndrome scales, internal reliability ranged from unacceptable (Chronback's alpha = 0.11, rule-breaking behavior among young women) to good (α≥0.71, anxiety/depression among young women). Anxiety/depression scores of ≥8.5 among young women also had good sensitivity (0.833) and specificity (0.754) to predict a true diagnosis. The YSR syndrome scales for social problems among young women and attention problems among young men also had fair consistency and validity measurements. Most YSR scores had significant positive correlations between baseline and post-one month administration. Measures of reliability and validity for most other YSR syndrome scales were fair to poor. CONCLUSIONS: The adapted, personally administered, Amharic version of the YSR has sufficient reliability and validity in identifying young vulnerable women with anxiety/depression and/or social problems, and young men with attention problems; which were the most common mental health disorders observed by psychiatrists among the migrant populations in this study. Further assessment of the applicability of the YSR among vulnerable young people for less common disorders in Ethiopia is needed.

OBJECTIVES: To examine whether nonbarrier modern contraceptive use is associated with less consistent condom use among Kenyan female sex workers (FSWs). STUDY DESIGN: Researchers recruited 579 FSWs using respondent-driven sampling. We conducted multivariate logistic regression to examine the association between consistent condom use and female-controlled nonbarrier modern contraceptive use. RESULTS: A total of 98.8% reported using male condoms in the past month, and 64.6% reported using female-controlled nonbarrier modern contraception. In multivariate analysis, female-controlled nonbarrier modern contraceptive use was not associated with decreased condom use with clients or nonpaying partners. CONCLUSION: Consistency of condom use is not compromised when FSWs use available female-controlled nonbarrier modern contraception. IMPLICATIONS: FSWs should be encouraged to use condoms consistently, whether or not other methods are used simultaneously.

We conducted a respondent driven sampling survey to estimate HIV prevalence and risk behavior among female sex workers (FSWs) in Nairobi, Kenya. Women aged 18 years and older who reported selling sex to a man at least once in the past 3 months were eligible to participate. Consenting FSWs completed a behavioral questionnaire and were tested for HIV and sexually transmitted infections (STIs). Adjusted population-based prevalence and 95 % confidence intervals (CI) were estimated using RDS analysis tool. Factors significantly associated with HIV infection were assessed using log-binomial regression analysis. A total of 596 eligible participants were included in the analysis. Overall HIV prevalence was 29.5 % (95 % CI 24.7-34.9). Median age was 30 years (IQR 25-38 years); median duration of sex work was 12 years (IQR 8-17 years). The most frequent client-seeking venues were bars (76.6 %) and roadsides (29.3 %). The median number of clients per week was seven (IQR 4-18 clients). HIV testing was high with 86.6 % reported ever been tested for HIV and, of these, 63.1 % testing within the past 12 months. Of all women, 59.7 % perceived themselves at 'great risk' for HIV infection. Of HIV-positive women, 51.0 % were aware of their infection. In multivariable analysis, increasing age, inconsistent condom use with paying clients, and use of a male condom as a method of contraception were independently associated with unrecognized HIV infection. Prevalence among STIs was low, ranging from 0.9 % for syphilis, 1.1 % for gonorrhea, and 3.1 % for Chlamydia. The data suggest high prevalence of HIV among FSWs in Nairobi. Targeted and routine HIV and STI combination prevention strategies need to be scaled up or established to meet the needs of this population.

There is a dearth of evidence on injection drug use and associated HIV infections in Kenya. To generate population-based estimates of characteristics and HIV/STI prevalence among people who inject drugs (PWID) in Nairobi, a cross-sectional study was conducted with 269 PWID using respondent-driven sampling. PWID were predominantly male (92.5 %). An estimated 67.3 % engaged in at least one risky injection practice in a typical month. HIV prevalence was 18.7 % (95 % CI 12.3-26.7), while STI prevalence was lower [syphilis: 1.7 % (95 % CI 0.2-6.0); gonorrhea: 1.5 % (95 % CI 0.1-4.9); and Chlamydia: 4.2 % (95 % CI 1.2-7.8)]. HIV infection was associated with being female (aOR, 3.5; p = 0.048), having first injected drugs 5 or more years ago (aOR, 4.3; p = 0.002), and ever having practiced receptive syringe sharing (aOR, 6.2; p = 0.001). Comprehensive harm reduction programs tailored toward PWID and their sex partners must be fully implemented as part of Kenya's national HIV prevention strategy.

Male sex workers who sell or exchange sex for money or goods encompass a very diverse population across and within countries worldwide. Information characterising their practices, contexts where they live, and their needs is limited, because these individuals are generally included as a subset of larger studies focused on gay men and other men who have sex with men (MSM) or even female sex workers. Male sex workers, irrespective of their sexual orientation, mostly offer sex to men and rarely identify as sex workers, using local or international terms instead. Growing evidence indicates a sustained or increasing burden of HIV among some male sex workers within the context of the slowing global HIV pandemic. Several synergistic facilitators could be potentiating HIV acquisition and transmission among male sex workers, including biological, behavioural, and structural determinants. Criminalisation and intersectional stigmas of same-sex practices, commercial sex, and HIV all augment risk for HIV and sexually transmitted infections among male sex workers and reduce the likelihood of these people accessing essential services. These contexts, taken together with complex sexual networks among male sex workers, define this group as a key population underserved by current HIV prevention, treatment, and care services. Dedicated efforts are needed to make those services available for the sake of both public health and human rights. Evidence-based and human rights-affirming services dedicated specifically to male sex workers are needed to improve health outcomes for these men and the people within their sexual networks.

: Previous surveys of men who have sex with men (MSM) in Africa have not adequately profiled HIV status and risk factors by sex work status. MSM in Nairobi, Kenya, were recruited using respondent-driven sampling, completed a behavioral interview, and were tested for HIV and sexually transmitted infections. Overlapping recruitment among 273 male sex workers and 290 other MSM was common. Sex workers were more likely to report receptive anal sex with multiple partners (65.7% versus 18.0%, P < 0.001) and unprotected receptive anal intercourse (40.0% versus 22.8%, P = 0.005). Male sex workers were also more likely to be HIV infected (26.3% versus 12.2%, P = 0.007).

Previous research on the use of personal lubricants for sexual intercourse is limited and has primarily focused on condom compatibility and breakage, with only recent limited assessment of lubricant safety and possible epidemiologic implications. This article discusses the global evidence of lubricant compatibility with latex condoms and biological safety of lubricants, as well as documentation of lubricant use and current guidelines for HIV prevention programming in Africa. Data on lubricant compatibility with condoms are less available than commonly realized, and many lubricant products may not have been thoroughly tested for safety due to flexible regulatory environments. Recent laboratory and study findings from microbicides research also suggest that some water-based lubricants may have safety issues. Some African populations are using several types of lubricants, especially oil-based petroleum jellies, and receive little evidence-based guidance. More research is needed from the medical community to guide prevention programming.

OBJECTIVES: Size estimates of populations at higher risk for HIV infection are needed to help policy makers understand the scope of the epidemic and allocate appropriate resources. Population size estimates of men who have sex with men (MSM), female sex workers(FSW) and intravenous drug users (IDU) are few or non-existent in Nairobi, Kenya. METHODS: We integrated three population size estimation methods into a behavioural surveillance survey among MSM, FSW and IDU in Nairobi during 20102011. These methods included the multiplier method, 'Wisdom of the Crowds' and an approach that drew on published literature. The median of the three estimates was hypothesised to be the most plausible size estimate with the other results forming the upper and lower plausible bounds. Data were shared with community representatives and stakeholders to finalise 'best' point estimates and plausible bounds based on the data collected in Nairobi, a priori expectations from the global literature and stakeholder input. RESULTS: We estimate there are approximately 11 042 MSM with a plausible range of 10 00022 222, 29 494 FSW with a plausible range of 10 00054 467 FSW and approximately 6107 IDU and plausibly 503110 937 IDU living in Nairobi. CONCLUSIONS: We employed multiple methods and used a wide range of data sources to estimate the size of three hidden populations in Nairobi, Kenya. These estimates may be useful to advocate for and to plan, implement and evaluate HIV prevention and care programmes for MSM, FSW and IDU. Surveillance activities should consider integrating population size estimation in their protocols.

OBJECTIVE: To investigate self-report of heterosexual anal intercourse among male sex workers who sell sex to men, and to identify the socio-demographic characteristics associated with practice of the behavior. DESIGN: Two cross-sectional surveys of male sex workers who sell sex to men in Mombasa, Kenya. METHODS: Male sex workers selling sex to men were invited to participate in surveys undertaken in 2006 and 2008. A structured questionnaire administered by trained interviewers was used to collect information on socio-demographic characteristics, sexual behaviors, HIV and STI knowledge, and health service usage. Data were analyzed through descriptive and inferential statistics. Bivariate logistic regression, after controlling for year of survey, was used to identify socio-demographic characteristics associated with heterosexual anal intercourse. RESULTS: From a sample of 867 male sex workers, 297 men had sex with a woman during the previous 30 days - of whom 45% did so with a female client and 86% with a non-paying female partner. Within these groups, 66% and 43% of male sex workers had anal intercourse with a female client and non-paying partner respectively. Factors associated with reporting recent heterosexual anal intercourse in bivariate logistic regression after controlling for year of survey participation were being Muslim, ever or currently married, living with wife only, living with a female partner only, living with more than one sexual partner, self-identifying as basha/king/bisexual, having one's own children, and lower education. CONCLUSIONS: We found unexpectedly high levels of self-reported anal sex with women by male sex workers, including selling sex to female clients as well as with their own partners. Further investigation among women in Mombasa is needed to understand heterosexual anal sex practices, and how HIV programming may respond.
