HIV testing among female sex workers and associated factors in Burkina Faso: findings from a respondent-driven sampling survey. BMC Public Health 2024; 24:2512. [PMID: 39285273 PMCID: PMC11403936 DOI: 10.1186/s12889-024-19977-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Accepted: 09/03/2024] [Indexed: 09/22/2024] Open
Abstract
BACKGROUND In Burkina Faso, only 70% of people living with HIV knew their status in 2018, while the first 95 target of the UNAIDS suggests that by 2025 at least 95% of people living with HIV (PLHIV) know their HIV status. Female sex workers (FSW) are one of the most HIV-vulnerable groups, making it crucial to estimate the rate and associated factors of HIV testing among FSW. METHODS We conducted a cross-sectional study focused on FSW in five main cities of Burkina Faso (Ouagadougou, Bobo-Dioulasso, Koudougou, Tenkodogo, and Ouahigouya). A respondent-driven sampling (RDS) approach was used to recruit participants. Data were collected through in-person interviews between June and August 2022. The HIV testing rate in the past twelve months was examined by sociodemographic characteristics and risky behaviors. A modified Poisson regression in a generalized estimating equation with an exchangeable correlation structure was used to explore the associated factors of HIV testing. RESULTS Of 1338 FSW (average age: 27.6 ± 7.25 years) HIV negative, 57.8% (95% CI: 54.2-61.3) reported having been tested for HIV in the last 12 months. Among those who started sex work before the age of 18, 48.0% (95% CI: 39.1-57.1) reported having been tested for HIV in the last 12 months. The HIV testing rate among FSWs within the last 12 months was independently associated with age, education level, and being member of an FSW supportive association. Indeed, FSW aged 25 years and more had a 14% higher rate of being tested for HIV within 12 months compared to those 15 to 24 years old (adjusted prevalence ratio (aPR): 1.14 [95%CI: 1.05-1.24]). The HIV testing rate among those who are not members of an FSW supportive association was 16% lower (aPR: 0.84 [95%CI: 0.72-0.97]) than those who are members of FSW supportive associations. CONCLUSION The HIV testing rate among FSW is low in Burkina Faso, suggesting an important challenge to reach the first 95% target of UNAIDS among FSW. Innovative diagnostic strategies for the early identification of HIV-infected FSW are essential to achieve the first 95 target by 2025 in Burkina Faso.

Abstract
BACKGROUND The objectives of this study were to determine the association between the vulnerability factors linked to human immunodeficiency virus (HIV) and other sexually transmitted infection among the young women who sell sex (YWSS) group (15-24 years) and adult sex workers, engaged in consensual sex for money (AFSW). METHODS A cross-sectional study was conducted among AFSW involved in commercial sex transactions. Prevalence ratios (PR) analysis was carried out using log-binomial regression model. RESULTS The prevalence of HIV-1 was 29.4% among YWSS compared to 19.6% among female sex worker (PR = 1.43 [1.07-1.91]). Consistent condoms use last 3 months were very low at 22.3% and 41.2%, respectively (PR = 0.52 [0.37-0.74]), the low education level among YWSS versus AFSW (PR = 0.55 [0.40-0.76]); YWSS having been a victim of sexual violence in the last 12 months (PR = 2.00 [1.52-2.63]), were also more likely to be HIV positive. CONCLUSIONS The YWSS had a high prevalence of HIV, experienced other socioeconomic vulnerabilities and remain a key population for comprehensive HIV programs. To reach all YWSS, programs need to consider many outreach programs and address the shared determinants of HIV risk.

Evidence and gap map report: Social and Behavior Change Communication (SBCC) interventions for strengthening HIV prevention and research among adolescent girls and young women (AGYW) in low- and middle-income countries (LMICs). CAMPBELL SYSTEMATIC REVIEWS 2023; 19:e1297. [PMID: 36911864 PMCID: PMC9831290 DOI: 10.1002/cl2.1297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Indexed: 06/18/2023]
Abstract
Background Adolescent girls and young women (AGYW), aged 15-24 years, are disproportionately affected by HIV and other sexual and reproductive health (SRH) risks due to varying social, cultural, and economic factors that affect their choices and shape their knowledge, understanding, and practices with regard to their health. Socio-Behavioral Change Communication (SBCC) interventions targeted at strengthening the capabilities of individuals and their networks have supported the demand and uptake of prevention services and participation in biomedical research. However, despite growing global recognition of the domain, high-quality evidence on the effectiveness of SBCC remains scattered. This evidence and gap map (EGM) report characterizes the evidence base on SBCC interventions for strengthening HIV Prevention and Research among AGYW in low- and middle-income countries (LMICs), identifying evidence gaps and outlining the scope of future research and program design. Objectives The objectives of the proposed EGM are to: (a) identify and map existing EGMs in the use of diverse SBCC strategies to strengthen the adoption of HIV prevention measures and participation in research among AGYW in LMICs and (b) identify areas where more interventions and evidence are needed to inform the design of future SBCC strategies and programs for AGYW engagement in HIV prevention and research. Methods This EGM is based on a comprehensive search of systematic reviews and impact evaluations corresponding to a range of interventions and outcomes-aimed at engaging AGYW in HIV prevention and research - that were published in LMICs from January 2000 to April 2021. Based on guidance for producing a Campbell Collaboration EGM, the intervention and outcome framework was designed in consultation with a group of experts. These interventions were categorized across four broad intervention themes: mass-media, community-based, interpersonal, and Information Communication and Technology (ICT)/Digital Media-based interventions. They were further sub-categorized into 15 intervention categories. Included studies looked at 23 unique behavioral and health outcomes such as knowledge attitude and skills, relationship dynamics, household dynamics, health care services, and health outcomes and research engagement. The EGM is presented as a matrix in which the rows are intervention categories/sub-categories, and the columns are outcome domains/subdomains. Each cell is mapped to an intervention targeted at outcomes. Additional filters like region, country, study design, age group, funding agency, influencers, population group, publication status, study confidence, setting, and year of publication have been added. Selection Criteria To be eligible, studies must have tested the effectiveness of SBCC interventions at engaging AGYW in LMICs in HIV prevention and research. The study sample must have consisted of AGYW between the ages of 15-24, as defined by UNAIDS. Both experimental (random assignment) and quasi-experimental studies that included a comparison group were eligible. Relevant outcomes included those at the individual, influencer, and institutional levels, along with those targeting research engagement and prevention-related outcomes. Results This EGM comprises 415 impact evaluations and 43 systematic reviews. Interventions like peer-led interactions, counseling, and community dialogues were the most dominant intervention sub-types. Despite increased digital penetration use of media and technology-driven interventions are relatively less studied. Most of the interventions were delivered by peers, health care providers, and educators, largely in school-based settings, and in many cases are part of sex-education curricula. Evidence across geographies was mostly concentrated in Sub-Saharan Africa (70%). Most measured outcomes focused on disease-related knowledge dissemination and enhancing awareness of available prevention options/strategies. These included messaging around consistent condom use, limiting sexual partners, routine testing, and awareness. Very few studies were able to include psychographic, social, and contextual factors influencing AGYW health behaviors and decisions, especially those measuring the impact of social and gender norms, relationship dynamics, and household dynamics-related outcomes. Outcomes related to engagement in the research were least studied. Conclusion This EGM highlights that evidence is heavily concentrated within the awareness-intent spectrum of behavior change and gets lean for outcomes situated within the intent-action and the action-habit formation spectrum of the behavior change continuum. Most of the evidence was concentrated on increasing awareness, knowledge, and building risk perception around SRH domains, however, fewer studies focused on strengthening the agency and self-efficacy of individuals. Similarly, evidence on extrinsic factors-such as strengthening social and community norms, relationships, and household dynamics-that determine individual thought and action such as negotiation and life skills were also found to be less populated. Few studies explore the effectiveness of these interventions across diverse AGYW identities, like pregnant women and new mothers, sex workers, and people living with HIV, leading to limited understanding of the use of these interventions across multiple user segments including key influencers such as young men, partners, families, religious leaders, and community elders was relatively low. There is a need for better quality evidence that accounts for the diversity of experiences within these populations to understand what interventions work, for whom, and toward what outcome. Further, the evidence for use of digital and mass-media tools remains poorly populated. Given the increasing penetration of these tools and growing media literacy on one end, with widening gender-based gaps on the other, it is imperative to gather more high-quality evidence on their effectiveness. Timely evidence generation can help leverage these platforms appropriately and enable intervention designs that are responsive to changing communication ecologies of AGYW. SBCC can play a critical role in helping researchers meaningfully engage and collaborate with communities as equal stakeholders, however, this remains poorly evidenced and calls for investigation and investment.

Abstract
Combination HIV prevention aims to provide the right mix of biomedical, behavioral and structural interventions, and is considered the best approach to curb the HIV pandemic. The impact evaluation of combined HIV prevention intervention (CHPI) provides critical information for decision making. We conducted a systematic review of the literature to map the designs and methods used in these studies. We searched original articles indexed in Web of Science, Scopus and PubMed. Fifty-eight studies assessing the impact of CHPI on HIV transmission were included. Most of the studies took place in Asia or sub-Saharan Africa and were published from 2000 onward. We identified 36 (62.1%) quasi-experimental studies (posttest, pretest-posttest and nonequivalent group designs) and 22 (37.9%) experimental studies (randomized designs). The findings suggest that diverse methods are already rooted in CHPI impact evaluation practices as recommended but should be better reported. CHPI impact evaluation would benefit from more comprehensive approaches.

Abstract
Background Adolescents experiencing multiple vulnerabilities, including poverty, curtailed education, transactional sex and early childbearing, are at risk of poor mental health. In Zimbabwe, girls who are pregnant or new mothers and involved in selling sex struggle to cope with the combined pressures of parenthood, financial insecurity, and social stigma. A pilot intervention brought such girls together into self-help groups to increase peer support, resources and skills. Objective This study aimed to explore whether and how participation in a self-help group intervention affected vulnerable young mothers’ experiences and perceptions of mental health stressors. Methods Self-help groups received 12 participatory sessions over 6 months. Eighteen semi-structured interviews and three focus group discussions were held with participants and drop-outs. Before and after the intervention, participants completed the locally validated 14-item Shona Symptom Questionnaire tool to indicate the probable prevalence of common mental health disorders. Results Adolescent girls described mutually reinforcing stressors in their lives and reported low self-esteem and anxiety. Key themes emerging from qualitative data centred around girls’ struggles with adverse life events, the burden of new motherhood, social isolation related to sex work and self-help groups as a source of hope. Participants joined groups to obtain support and felt their mental well-being improved due to new social networks, feelings of solidarity with peers, and increased confidence for positive action, that is, seeking health services for themselves and their babies. Prior to enrolment 16% showed signs of possible common mental disorders falling to 2% at follow-up. Conclusions Participants believed involvement in interactive self-help groups improved their mental health by strengthening peer support and engendering hope for the future. Although reduced mental distress cannot be attributed to the programme, the pilot intervention offers a low-cost approach that could be rigorously tested and adapted to a wide range of community settings.

Abstract
INTRODUCTION In 2018, the National AIDS and sexually transmitted infection (STI) Control Programme developed a national guidelines to facilitate the inclusion of young women who sell sex (YWSS) in the HIV prevention response in Kenya. Following that, a 1-year pilot intervention, where a package of structural, behavioural and biomedical services was provided to 1376 cisgender YWSS to address their HIV-related risk and vulnerability, was implemented. METHODS Through a mixed-methods, pre/post study design, we assessed the effectiveness of the pilot, and elucidated implementation lessons learnt. The three data sources used included: (1) monthly routine programme monitoring data collected between October 2019 and September 2020 to assess the reach and coverage; (2) two polling booth surveys, conducted before and after implementation, to determine the effectiveness; and (3) focus group discussions and key informant interviews conducted before and after intervention to assess the feasibility of the intervention. Descriptive analysis was performed to produce proportions and comparative statistics. RESULTS During the intervention, 1376 YWSS were registered in the programme, 28% were below 19 years of age and 88% of the registered YWSS were active in the last month of intervention. In the survey, respondents reported increases in HIV-related knowledge (61.7% vs. 90%, p <0.001), ever usage of pre-exposure prophylaxis (8.5% vs. 32.2%, p < 0.001); current usage of pre-exposure prophylaxis (5.3% vs. 21.1%, p<0.002); ever testing for HIV (87.2% vs. 95.6%, p <0.04) and any clinic visit (35.1 vs. 61.1, p <0.001). However, increase in harassment by family (11.7% vs. 23.3%, p<0.04) and discrimination at educational institutions (5.3% vs. 14.4%, p<0.04) was also reported. In qualitative assessment, respondents reported early signs of success, and identified missed opportunities and made recommendations for scale-up. CONCLUSIONS Our intervention successfully rolled out HIV prevention services for YWSS in Mombasa, Kenya, and demonstrated that programming for YWSS is feasible and can effectively be done through YWSS peer-led combination prevention approaches. However, while reported uptake of treatment and prevention services increased, there was also an increase in reported harassment and discrimination requiring further attention. Lessons learnt from the pilot intervention can inform replication and scale-up of such interventions in Kenya.

The impact of the DREAMS partnership on HIV incidence among young women who sell sex in two Zimbabwean cities: results of a non-randomised study. BMJ Glob Health 2021; 6:bmjgh-2020-003892. [PMID: 33906844 PMCID: PMC8088246 DOI: 10.1136/bmjgh-2020-003892] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 03/06/2021] [Accepted: 03/16/2021] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION Young women who sell sex (YWSS) in Zimbabwe remain at high risk of HIV infection. Effective HIV prevention strategies are needed. Through support to access a combination of evidence-based interventions, including oral pre-exposure prophylaxis (PrEP), the Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS) partnership aimed to reduce new HIV infections among adolescent girls and young women by 40% over 24 months. METHODS Non-randomised 'plausibility' evaluation, powered to detect a 40% HIV incidence difference between DREAMS and non-DREAMS sites. Two large cities with DREAMS funding were included, and four smaller non-DREAMS towns for comparison. In all sites, YWSS were enrolled to a cohort through peer-referral. Women were followed up for 24 months. HIV seroconversion was the primary outcome, with secondary outcomes identified through a theory of change. Outcomes were compared between YWSS recruited in DREAMS cities and non-DREAMS towns, adjusting for individual-level confounders and HIV prevalence at enrolment. RESULTS From April to July 2017, 2431 women were enrolled, 1859 of whom were HIV negative at enrolment; 1019 of these women (54.8%) were followed up from March to May 2019 and included in endline analysis. Access to clinical services increased, but access to socioeconomic interventions promoted by DREAMS was limited. A total of 79 YWSS HIV seroconverted, with HIV incidence among YWSS in DREAMS cities lower (3.1/100 person-years) than in non-DREAMS towns (5.3/100 person-years). In prespecified adjusted analysis, HIV incidence was lower in DREAMS cities but with weak statistical evidence (adjusted rate ratio (RR)=0.68; 95% CI 0.40 to 1.19; p=0.18). Women in DREAMS cities were more likely to report ever and ongoing PrEP use, consistent condom use, fewer sexual partners and less intimate partner violence. CONCLUSION It is plausible that DREAMS lowered HIV incidence among YWSS in two Zimbabwean cities, but our evaluation provides weak statistical evidence for impact and suggests any reduction in incidence was lower than the anticipated 40% decline. We identified changes to some important 'pathways to impact' variables, including condom use.

[PMID: 32398032 PMCID: PMC7218508 DOI: 10.1186/s12879-020-05003-9] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Accepted: 03/30/2020] [Indexed: 12/23/2022] Open
Abstract
Background Peer education has become a strategy for health promotion among high-risk groups for HIV infection worldwide. However, the extent to which peer education could have an impact on HIV prevention or the long-term effect of this impact is still unknown. This study thus quantifies the impact of peer education over time among high-risk HIV groups globally. Method Following the PRISMA guidelines, a systematic review and meta-analysis was used to assess the effects and duration of peer education. A thorough literature search of PubMed, Web of Science, Embase and Cochrane Library was performed, and studies about peer education on high-risk HIV groups were reviewed. Pooled effects were calculated and the sources of heterogeneity were explored using meta-regression and subgroup analysis. Results A total of 60 articles with 96,484 subjects were identified, and peer education was associated with 36% decreased rates of HIV infection among overall high risk groups (OR: 0.64; 95%CI: 0.47–0.87). Peer education can promote HIV testing (OR = 3.19; 95%CI:2.13,4.79) and condom use (OR = 2.66, 95% CI: 2.11–3.36) while reduce equipment sharing (OR = 0.50; 95%CI:0.33,0.75) and unprotected sex (OR = 0.82; 95%CI: 0.72–0.94). Time trend analysis revealed that peer education had a consistent effect on behavior change for over 24 months and the different follow-up times were a source of heterogeneity. Conclusion Our study shows that peer education is an effective tool with long-term impact for behavior change among high-risk HIV groups worldwide. Low and middle-income countries are encouraged to conduct large-scale peer education.

[PMID: 32302334 PMCID: PMC7164600 DOI: 10.1371/journal.pone.0231640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 03/29/2020] [Indexed: 11/19/2022] Open
Abstract
Background Members of uniformed armed forces are considered to be at high risk for HIV infection and have been proposed as suitable candidates for participation in HIV intervention studies. We report on the feasibility of recruitment and follow up of individuals from the community of the Uganda Police Force (UPF) for an HIV vaccine preparedness study. Methods HIV-negative volunteers aged 18–49 years, were identified from UPF facilities situated in Kampala and Wakiso districts through community HIV counselling and testing. Potential volunteers were referred to the study clinic for screening, enrolment and quarterly visits for one year. HIV incidence, retention rates were estimated and expressed as cases per 100 person years of observation (PYO). Rate ratios were used to determine factors associated with retention using Poisson regression models. Results We screened 560 to enroll 500 volunteers between November 2015 and May 2016. One HIV seroconversion occurred among 431 PYO, for an incidence rate of 0.23/100 PYO (95% confidence interval [CI]: 0.03–1.64). Overall, retention rate was 87% at one year, and this was independently associated with residence duration (compared to <1 year, 1 to 5 years adjusted rate ratio (aRR) = 1.19, 95%CI: 1.00–1.44); and >5 years aRR = 1.34, 95%CI: 0.95–1.37); absence of genital discharge in the last 3 months (aRR = 1.97, 95% CI: 1.38–2.83, absence of genital ulcers (aRR = 1.90, 95%CI: 1.26–2.87, reporting of new sexual partner in the last month (aRR = 0.57, 95%CI: 0.45–0.71, being away from home for more than two nights (aRR = 1.27, 95%CI: 1.04–1.56, compared to those who had not travelled) and absence of knowledge on HIV prevention (aRR = 2.67, 95%CI: 1.62–4.39). Conclusions While our study demonstrates the feasibility of recruiting and retaining individuals from the UPF for HIV research, we did observe lower than anticipated HIV incidence, perhaps because individuals at lower risk of HIV infection may have been the first to come forward to participate or participants followed HIV risk reduction measures. Our findings suggest lessons for recruitment of populations at high risk of HIV infection.

Transactional sex among men who have sex with men participating in the CohMSM prospective cohort study in West Africa. PLoS One 2019; 14:e0217115. [PMID: 31693669 PMCID: PMC6834336 DOI: 10.1371/journal.pone.0217115] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Accepted: 10/21/2019] [Indexed: 01/22/2023] Open
Abstract
Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d’Ivoire, Mali and Togo. Three stigmatization sub-scores were constructed (experienced, perceived and internalized). The generalized estimating equation method was used for data analysis. Of the total 630 HIV-negative MSM recruited in CohMSM, 463, 410 and 244 had a follow-up visit at 6, 12 and 18 months, respectively. In a total of 1747 follow-up visits, 478 TS encounters were reported by 289 MSM-TS (45.9%). Of the latter, 91 regularly reported TS (31.5%), 55 (19.0%) stopped reporting TS after baseline, and 53 (18.3%) reported TS after baseline and 90 (31.1%) occasionally reported TS. The following variables, regarding the previous 6 months, were positively associated with TS: being younger (aOR[95%CI]:1.86[1.39–2.50]), less educated (aOR[95%CI]:1.49[1.09–2.03]), unmarried status (aOR[95%CI]:1.79[1.10–2.93]), satisfaction with current sex life (aOR[95%CI]:1.41[1.06–1.88]), group sex with men (aOR[95%CI]:2.07[1.46–2.94]), multiple male sexual partners (aOR[95%CI]:1.85[1.40–2.44]), receptive or versatile anal sex with male partners (aOR [95%CI]:1.48[1.12–1.96]), giving benefits in exchange for sex with a man (aOR[95%CI]:2.80[1.97–3.98]), alcohol consumption (aOR[95%CI]:1.44[1.08–1.93]) and drug use (aOR[95%CI]:1.82[1.24–2.68]) during sex, and finally experiencing stigmatization (aOR [95%CI]:1.15[1.07–1.25]). Condom use during anal sex (aOR[95%CI]:0.73[0.53–0.99]) was negatively associated with TS.

Abstract
Background: Globally about 210 million women conceive annually and 38% of these pregnancies are unintended. Female sex workers (FSWs) are at increased risk of both unintended pregnancy and acquiring HIV, which could lead to adverse sexual and reproductive health (SRH) outcomes. We sought to assess contraceptive use or non-use, preferences and determinants among a cohort of FSWs screened for an HIV prevention clinical trial in Kisumu, Kenya. Methods: A cross sectional study of healthy FSWs referred for possible recruitment into the Antibody Mediated HIV Prevention (AMP) Study was conducted between December 2016 and September 2018. Potentially eligible participants were screened for HIV and data on social-demographic, contraceptive use and other SRH characteristics were collected. Those not on a method recorded their contraceptive preferences. Results: Data on 210 FSWs with a median age of 24.5 years (interquartile range, IQR 22-26) are presented. Of these, 187 (89.1%) had two children or fewer; only 56 (26.7%) had completed secondary or higher education. At the time of the interview, 18 (8.6%) were HIV-infected and 181 (86.2%) were using a modern contraceptive. Implants (48.6%) and depot injections (37.6%) were the most commonly used methods. Most (41.4%) of those not on family planning preferred oral pills. Respondents who had two or more children were three times more likely than their primiparous and nulliparous counterparts to report use of a contraceptive. Use of modern contraception methods did not differ by respondent’s ownership of a medical insurance cover or other occupation. Conclusion: There is high use of modern contraception among FSWs in Kisumu with the majority using subdermal implants. Reproductive health programs should implement targeted SRH interventions for specific populations and risk groups. Effective contraceptive counselling and interventions among FSWs should consider the client’s parity and level of education.

Abstract
INTRODUCTION Providing outreach HIV prevention services at venues (i.e. "hotspots") where people meet new sex partners can decrease barriers to HIV testing services (HTS) for key populations (KP) in sub-Saharan Africa (SSA). We offered venue-based HTS as part of bio-behavioural surveys conducted in urban Malawi and Angola to generate regional insights into KP programming gaps and identify opportunities to achieve the "first 90" for KP in SSA. METHODS From October 2016 to March 2017, we identified and verified 1054 venues in Luanda and Benguela, Angola and Zomba, Malawi and conducted bio-behavioural surveys at 166 using the PLACE method. PLACE interviews community informants to systematically identify public venues where KP can be reached and conducts bio-behavioural surveys at a stratified random sample of venues. We present survey results using summary statistics and multivariable modified Poisson regression modelling to examine associations between receipt of outreach worker-delivered HIV/AIDS education and HTS uptake. We applied sampling weights to estimate numbers of HIV-positive KP unaware of their status at venues. RESULTS We surveyed 959 female sex workers (FSW), 836 men who have sex with men (MSM), and 129 transgender women (TGW). An estimated 71% of HIV-positive KP surveyed were not previously aware of their HIV status, receiving a new HIV diagnosis through PLACE venue-based HTS. If venue-based HTS were implemented at all venues, 2022 HIV-positive KP (95% CI: 1649 to 2477) who do not know their status could be reached, including 1666 FSW (95% CI: 1397 to 1987), 274 MSM (95% CI: 160 to 374), and 82 TG (95% CI: 20 to 197). In multivariable analyses, FSW, MSM, and TGW who received outreach worker-delivered HIV/AIDS education were 3.15 (95% CI: 1.99 to 5.01), 3.12 (95% CI: 2.17 to 4.48), and 1.80 (95% CI: 0.67 to 4.87) times as likely, respectively, as those who did not to have undergone HTS within the last six months. Among verified venues, <=68% offered any on-site HIV prevention services. CONCLUSIONS Availability of HTS and other HIV prevention services was limited at venues. HIV prevention can be delivered at venues, which can increase HTS uptake and HIV diagnosis among individuals not previously aware of their status. Delivering venue-based HTS may represent an effective strategy to reach the "first 90" for KP in SSA.

Abstract
Female sex workers (FSWs) continue to carry a heavy burden of sexually transmitted infections (STI). For prevention purposes, there is a need to identify most-at-risk subgroups among them. The objective of this longitudinal cohort study conducted at Dispensaire IST, Cotonou, Benin, was to assess Neisseria gonorrhoeae (NG) / Chlamydia trachomatis (CT) incidence and determinants; and HIV incidence among FSWs in presence of STI/HIV risk reduction activities. Overall, 319 adult FSWs were followed quarterly from September 2008 to March 2012. NG/CT were detected from endocervical swabs by Amplified DNA Assays employing Strand displacement amplification technology. HIV testing was done on capillary blood using two consecutive rapid diagnostic tests. Anderson-Gill proportional hazard models (HR) were used to determine factors independently associated with NG/CT incidence. The majority of FSWs were HIV-negative (188, 58.9%). There were 6 HIV seroconversions among these 188 HIV-negative women. HIV incidence (95% Confidence interval, CI) was 1.41 (0.28–2.54) seroconversions per 100 person-years at risk (PYAR): 6 events / 425.1 PYAR. Sixty-two out of 319 women experienced 83 new episodes of NG/CT for an overall incidence rate (95% CI) of 10.8 (8.17–13.88) events / 100 PYAR. From month-24 onwards, HIV-positive women (treated: HR (95%CI): 4.2 (1.60–10.77); untreated: HR (95%CI): 4.2 (1.59–11.49) were more likely to acquire NG/CT compared to HIV-negative FSWs. Longer duration in sex work (>2 years: HR; 95%CI: 0.4 (0.22–0.72)) was protective against NG/CT. Refusal by clients (55.8%) was the main reason for non-condom use. Enrolling women from one clinic (Dispensaire IST) may have impaired generalizability of the findings. New NG/CT/HIV infections were observed among FSWs notwithstanding ongoing prevention interventions. To eliminate HIV transmission among FSWs, STI/HIV control programs need to promote women’s empowerment and address vulnerability to infection of HIV-positive FSWs.

Abstract
Ending acquired immune deficiency syndrome (AIDS) depends on greater efforts to reduce new human immunodeficiency virus (HIV) infections and prevent AIDS-related deaths among key populations at highest HIV risk, including males who have sex with males, sex workers, and people who inject drugs. Although adolescent key populations (AKP) are disproportionately affected by HIV, they have been largely ignored in HIV biological behavioral surveillance survey (BBSS) activities to date. This paper reviews current ethical and sampling challenges and provides suggestions to ensure AKP are included in surveillance activities, with the aim being to enhance evidence-informed, strategic, and targeted funding allocations and programs toward ending AIDS among AKP. HIV BBSS, conducted every few years worldwide among adult key populations, provide information on HIV and other infections’ prevalence, HIV testing, risk behaviors, program coverage, and when at least three of these surveys are conducted, trend data with which to evaluate progress. We provide suggestions and recommendations on how to make the case to ethical review boards to involve AKP in surveillance while assuring that AKP are properly protected. We also describe two widely used probability sampling methods, time location sampling and respondent driven sampling, and offer considerations of feature modifications when sampling AKP. Effectively responding to AKP’s HIV and sexual risks requires the inclusion of AKP in HIV BBSS activities. The implementation of strategies to overcome barriers to including AKP in HIV BBSS will result in more effective and targeted prevention and intervention programs directly suited to the needs of AKP.

Abstract
OBJECTIVE The incidence of HIV and sexually transmitted infections is disproportionately high among sex workers (SW). We aimed to update the evidence on the effectiveness of SW interventions in sub-Saharan Africa and to provide more insights into combination prevention. METHODS The Systematic review followed PRISMA guidelines in a search of PUBMED and POPLINE for peer-reviewed literature published between 1 January 2000 and 22 July 2016 (registration number on PROSPERO: CRD42016042529). We considered cohort interventions, randomised controlled trials and cross-sectional surveys of SW programmes. A framework was used in the description and mapping of intervention to desired outcomes. RESULTS Twenty-six papers(reporting on 25 studies) were included. A strategy that empowered peer educator leaders to steer community activities showed a twofold increase in coverage of behaviour change communication and utilisation of health facility among SW. Brief alcohol harm reduction effort demonstrated a significant effect on sexual violence and engagement in sex trading. A risk reduction counselling intervention among drug-injecting SW showed an effect on alcohol, substance use and engagement in sex work. No study on a promising intervention like PrEP among SWs was found. We observed that interventions that combined some structural components, biomedical and behavioural strategies tend to accumulate more desired outcomes. CONCLUSION The evidence base that can be considered in intervention designs to prevent HIV in SW in SSA is vast. The health sector should consider interventions to reduce binge alcohol intake and intravenous drug use among sex workers. Programmes should staunchly consider multicomponent approaches that explore community-based structural approaches.

Abstract
Background HIV prevalence among female sex workers (FSWs) in high burden countries in sub-Saharan Africa varies between 24 and 72%, however their access to HIV services remains limited. This study explored FSWs’ perspectives of the barriers and opportunities to HIV service access in Uganda. Methods The cross-sectional qualitative study was conducted between October and December 2013. Twenty-four focus group discussions were conducted with 190 FSWs in 12 districts. Data were analysed using manifest content analysis, using Atlas.ti software, based on the socio-ecological model. Results FSWs indicated that HIV services were available and these included condoms, HIV testing and treatment, and management of sexually transmitted infections. However, access to HIV services was affected by several individual, societal, structural, and policy related barriers. Individual level factors included limited awareness of some prevention services, fears, and misconceptions while societal stigma was prominent. Structural and policy level barriers included inconvenient hours of operation of the clinics, inflexible facility based distribution of condoms, interuptions in the supply of condoms and other commodities, and limited package of services with virtually no access to lubricants, HIV pre- and post-exposure prophylaxis, and support following client perpetrated violence. Policies such as partner testing and involvement at antenatal care, and using only one facility for antiretroviral drug refills hindered HIV service uptake and retention in care. FSWs had major concerns with the quality of services especially discrimination and rude remarks from providers, denial or delay of services, and potential for breach of confidentiality. However, some FSWs reported positive experiences including interface with friendly providers and participated in formal and informal FSW groups, which supported them to access health services. Conclusion Despite availability of services, FSWs faced major challenges in access to services. Comprehensive multilevel interventions targeting individual, societal, structural and policy level barriers are required to increase access to HIVservices among FSWs in Uganda. Policy and institutional adjustments should emphasize quality friendly services and expanding the package of services to meet the needs of FSWs.

Buck M, Dickson-Gomez J, Bodnar G. Combination HIV Prevention Strategy Implementation in El Salvador: Perceived Barriers and Adaptations Reported by Outreach Peer Educators and Supervisors. Glob Qual Nurs Res 2017; 4:2333393617703198. [PMID: 28462359 PMCID: PMC5406143 DOI: 10.1177/2333393617703198] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2016] [Revised: 02/01/2017] [Accepted: 02/24/2017] [Indexed: 11/15/2022] Open
Abstract
El Salvador was one of three countries to receive funding from the Global Fund to Fight AIDS, Tuberculosis and Malaria to conduct a combination HIV prevention intervention among transwomen (TW), men who have sex with men (MSM), and commercial sex workers (CSW). Program evaluation revealed that prevention activities reached only 50% of the target population. The purpose of this study is to examine the barriers that Salvadoran educators faced in implementing the peer education as designed and adaptations made as a result. Between March and June 2015, 18 in-depth interviews with educators were conducted. Violence was reported as the biggest barrier to intervention implementation. Other barriers differed by subpopulation. The level of violence and discrimination calls into question the feasibility and appropriateness of peer-led interventions in the Salvadoran context and demonstrates the importance of implementation research when translating HIV prevention interventions developed in high-income countries to low- and middle-income countries.

"A Baby Was an Added Burden": Predictors and Consequences of Unintended Pregnancies for Female Sex Workers in Mombasa, Kenya: A Mixed-Methods Study. PLoS One 2016; 11:e0162871. [PMID: 27689699 PMCID: PMC5045288 DOI: 10.1371/journal.pone.0162871] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2015] [Accepted: 08/30/2016] [Indexed: 11/18/2022] Open
Abstract
INTRODUCTION Female sex workers (FSW) have high rates of unintended pregnancy, sexually transmitted infections including HIV, and other adverse sexual and reproductive health outcomes. Few services for FSWs include contraception. This mixed-methods study aimed to determine the rate, predictors and consequences of unintended pregnancy among FSWs in Mombasa, Kenya. METHODS A prospective cohort study of non-pregnant FSWs was conducted. Quantitative data were collected quarterly, including a structured questionnaire and testing for pregnancy and HIV. Predictors of unintended pregnancy were investigated using multivariate logistic regression. Qualitative data were gathered through focus group discussions and in-depth interviews with FSWs who became pregnant during the study, and interviews with five key informants. These data were transcribed, translated and analysed thematically. RESULTS Four hundred women were enrolled, with 92% remaining in the cohort after one year. Fifty-seven percent reported using a modern contraceptive method (including condoms when used consistently). Over one-third (36%) of women were using condoms inconsistently without another method. Twenty-four percent had an unintended pregnancy during the study. Younger age, having an emotional partner and using traditional or no contraception, or condoms only, were independent predictors of unintended pregnancy. Women attributed pregnancy to forgetting to use contraception and being pressured not to by clients and emotional partners, as well as "bad luck". They described numerous negative consequences of unintended pregnancy. CONCLUSION Modern contraceptive uptake is surprisingly low in this at-risk population, which in turn has a high rate of unintended pregnancy. The latter may result in financial hardship, social stigma, risk of abandonment, or dangerous abortion practices. FSWs face considerable barriers to the adoption of dual method contraceptive use, including low levels of control in their emotional and commercial relationships. Reproductive health services need to be incorporated into programs for sexually transmitted infections and HIV, which address the socially-determined barriers to contraceptive use.

Declining HIV Prevalence in Parallel With Safer Sex Behaviors in Burkina Faso: Evidence From Surveillance and Population-Based Surveys. GLOBAL HEALTH: SCIENCE AND PRACTICE 2016; 4:326-35. [PMID: 27353624 PMCID: PMC4982255 DOI: 10.9745/ghsp-d-16-00013] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Accepted: 05/25/2016] [Indexed: 11/15/2022]
Abstract
HIV prevalence among pregnant women ages 15–49 declined from 7.1% to 2.0% in urban areas between 1998 and 2014, and from 2.0% to 0.5% in rural areas between 2003 and 2014; similar declines were reported in the Demographic and Health Surveys. During the same time period, individuals reported safer sex behaviors, including delayed sexual debut and reduced number of sex partners among youth, as well as increased condom use at last sex with nonmarital partners among men and women ages 15–49. Objective: To investigate trends in HIV prevalence and changes in reported sexual behaviors between 1998 and 2014 in Burkina Faso. Methods: We obtained data on HIV prevalence from antenatal care (ANC) surveillance sites (N = 9) that were consistently included in surveillance between 1998 and 2014. We also analyzed data on HIV prevalence and reported sex behaviors from 3 population-based surveys from the Demographic and Health Surveys (DHS), conducted in 1998–99, 2003, and 2010. Sex behavior indicators comprised never-married youth who have never had sex; sex with more than 1 partner; sex with a nonmarital, non-cohabiting partner; condom use at last sex with a nonmarital, non-cohabiting partner; and sex before age 15. We calculated survey-specific HIV prevalence with 95% confidence intervals (CIs) and used the chi-square test or chi-square test for trend to compare HIV prevalence across survey years and to analyze trends in reported sex behaviors. Results: HIV prevalence among pregnant women ages 15–49 decreased by 72% in urban areas, from 7.1% in 1998 to 2.0% in 2014, and by 75% in rural areas, from 2.0% in 2003 to 0.5% in 2014. HIV declined most in younger age groups, which is a good reflection of recent incidence, with declines of 55% among 15–19-year-olds, 72% among 20–24-year-olds, 40% among 25–29-year-olds, and 7% among those ≥30 years old (considering urban and rural data combined). Data reported in the DHS corroborated these declines in HIV prevalence: between 2003 and 2010, HIV prevalence dropped significantly—by 89% among girls ages 15–19, from 0.9% (95% CI, 0.2 to 1.6) to 0.1% (95% CI, 0.0 to 0.4), and by 78% among young women ages 20–24, from 1.8% (95% CI, 1.6 to 3.0) to 0.4% (95% CI, 0.0 to 0.7). During the same time period, people reported safer sex behaviors. For example, significantly higher percentages of never-married youth reported they had never had sex, lower percentages of sexually active youth reported multiple sex partners, and lower percentages of youth reported having sex before age 15. In addition, the percentage of men ages 20–49 reporting sex with a nonmarital, non-cohabiting partner declined significantly, while condom use at last sex with such a partner increased significantly among both men and women ages 15–49. Conclusions: Both ANC surveillance and population-based surveys report sharp declines in HIV prevalence in Burkina Faso between 1998 and 2014, accompanied by improvements in reported risky sex behaviors.

Abstract
Young women who sell sex (YWSS) in Southern Africa are highly vulnerable to HIV, as the risks of being young and female in a high prevalence setting coalesce with those of commercial sex. YWSS are less able to negotiate safe sex, more likely to have higher risk partners, and less likely to use available health services compared to older sex workers. In Zimbabwe's national HIV programme for sex workers, fewer than 1% of clients were 15-29. We developed monthly interactive workshops for YWSS based on an Activity Pack consisting of 21 sessions organised into six modules. The aim was to encourage YWSS' interaction with each other, build their trust, confidence and skills, and encourage uptake of clinical services. We conducted a process evaluation to assess programme strengths, identify challenges, and recommend changes. This paper presents findings synthesising programme records with qualitative data and discusses feasibility, acceptability, and outputs during the pilot phase. In total, 143 YWSS attended meetings and most were from the target 15-19-year-old age group. Participants enjoyed the sessions and reported improved cooperation, willingness to negotiate with clients, and self-reflection about their futures. Staff found facilitating sessions easy and activities clear and appropriate. Challenges included identifying appropriate referrals, initial recruitment of women in some sites, and managing participants' requests for financial compensation. The number of clients aged 15-19 increased at sex worker clinics in all sites. This programme is the first to target YWSS in Zimbabwe to address their disproportionately low service use. It proved feasible to staff and acceptable to participants over a one-year period. Given enhanced vulnerability of YWSS, this programme provides one workable model for reaching this underserved group.

HIV risk and behaviour among part-time versus professional FSW: baseline report of an interventional cohort in Burkina Faso. Sex Transm Infect 2016; 92:550-553. [PMID: 26834073 DOI: 10.1136/sextrans-2015-052038] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2015] [Revised: 12/16/2015] [Accepted: 01/09/2016] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE To readjust HIV control programmes in Africa, we assessed the factors associated with high-risk behaviours and HIV infection among young female sex workers (FSW) in Burkina Faso. METHODS We carried out a cross-sectional study from September 2009 to September 2010 in Ouagadougou, the capital city. FSW were categorised as professionals and part-time sex workers (PTSW). After a face-to-face questionnaire, blood and urine samples were collected for HIV, HSV-2, genital infections and pregnancy. High-risk behaviour was defined as a recent unprotected sex with either casual clients, regular clients or regular partners. RESULTS We recruited 609 FSW including 188 (30.9%) professionals. Their median age was 21 years (IQR 19-23), and the prevalence of HIV was 10.3% among professionals and 6.5% among PTSW. Only 3 of 46 HIV-infected women were aware of their status. Overall, 277 (45.6%) women reported high-risk behaviours (41.2% among professionals and 47.5% among PTSW), which were driven mainly by non-systematic condom use with regular partners. In multivariable analysis, PTSW (adjusted OR (AOR)=1.89; 95% CI 1.27 to 2.82) and having a primary (AOR=1.75; 95% CI 1.15 to 2.67) or higher education level (AOR=1.80; 95% CI 1.13 to 2.89) remained associated with high-risk behaviours. HIV infection was associated with older age (AOR=1.44; 95% CI 1.22 to 1.71), with being married/cohabiting (AOR=2.70; 95% CI 1.21 to 6.04) and with Trichomonas vaginalis infection (AOR=9.63; 95% CI 2.93 to 31.59), while history of HIV testing was associated with a decreased risk (AOR=0.18; 95% CI 0.08 to 0.40). CONCLUSIONS This study highlights the need for targeted interventions among young FSW focusing particularly on PTSW, sexual behaviours with regular partners and regular HIV testing.
