Systematic review of sex work interventions in sub-Saharan Africa: examining combination prevention approaches

Conducting high-frequency data collection in low-resource settings: Lessons from a financial diary study among women engaged in sex work in Uganda

Poverty and economic insecurity are driving forces in entering sex work among women in low resource areas. This increases their risk for HIV by influencing the decision-making process for high-risk behaviors. Few studies examine financial behaviors and capacities of women engaged in sex work (WESW). This paper describes the methodology used in a financial diary study aimed at characterizing women's spending patterns within a larger prevention intervention trial among WESW in Uganda. From June 2019 to March 2020, a subsample of 150 women randomized to the combination HIV prevention and economic empowerment treatment were asked to complete financial diaries to monitor daily expenditures in real time. Two hundred forty financial diaries were distributed to study participants during the financial literacy sessions at 8 sites. A total of 26,919 expense entries were recorded over 6 months. Sex work related expenses comprised approximately 20.01% of the total. The process of obtaining quality and consistent data was challenging due to the transient and stigmatized nature of sex work coupled with women's varying levels of education. Frequent check-ins, using peer support, code word or visuals, and a shorter timeframe would allow for a more accurate collection of high frequency data. Moreover, the ability of women to complete the financial diaries despite numerous challenges speaks to their potential value as a data collection tool, and also as an organizing tool for finances.

High burden of self-reported sexually transmitted infections among female sex workers in Togo in 2021

Background

Sexually Transmitted Infections (STI) remain a public health challenge, especially for Female Sex Workers (FSW) who are particularly vulnerable. In sub-Saharan Africa where the overlapping epidemics of STI and HIV are concentrated among key populations, epidemiological data are needed in order to better understand STI trends in this population. The aim of this study was to assess the prevalence of self-reported STI symptoms and their risk factors among FSW in Togo in 2021.

Methods

A cross-sectional study was completed in June and July 2021 among FSW in two cities of Togo: in Lomé (capital city, south of Togo) and in Kara (north of Togo). A snowball sampling method was used and after consent, a standardized questionnaire was administered by trained research staff to collect information on STI. A multivariate logistic regression model was used to identify factors associated with self-reported STI.

Results

A total of 447 FSW, 300 in Lomé and 147 in Kara participated in this study. Median age was 30 [IQR: 24-38] and STI symptoms in the previous 12 months were reported by 191 FSW [42.7%, 95% CI: (38.1-47.5)], among whom 116 (60.7%) sought medical care. The most common reported symptoms were abnormal vaginal discharge (n = 78; 67.2%) and vaginal itching (n = 68; 58.6%). Current STI symptoms (at the time of the survey) were reported by 88 FSW (19.7%). In multivariable logistic regression, self-reported STI symptoms in the previous 12 months was negatively associated with living in the Lomé and older age and positively associated with having more than 15 clients in the previous week and being victim of violence.

Conclusions

Findings from this study reveal that the self-reported STI burden is relatively high among FSW Togo. Additional strategies are needed at the structural, medical, political and social levels to curb this trend and effectively aim at the elimination of STI epidemics by the year 2030.

“Whatever is in the ARVs, is Also in the PrEP” Challenges Associated With Oral Pre-exposure Prophylaxis Use Among Female Sex Workers in South Africa

Background

The national policy on oral pre-exposure prophylaxis (PrEP) for female sex workers (FSWs) was instituted in South Africa in 2016. FSWs were targeted for PrEP due to a Human immunodeficiency virus (HIV) prevalence of 57.7%, which is higher than the prevalence of 19.07% among the general population. Research from demonstration studies has shown that uptake of PrEP has been slower than anticipated, and the purpose of this study was to explore barriers to the uptake of PrEP among FSWs.

Methods

An in-depth qualitative study was conducted with 39 participants, 30 individual participants, and nine focus group participants. Eleven participants consisted of peer educators and two health workers from a sex work and PrEP distribution organization, the rest of the participants (1) were FSWs.

Results

The majority of participants mentioned that little distinction was made between PrEP and antiretrovirals (ARVs) taken by FSWs living with HIV. PrEP was not distributed through public health care facilities, and health workers unknowingly labeled PrEP as ARVs. Consequently, health workers seen as experts created suspicion and contributed to the mistrust of PrEP among FSWs due to mixed messages, and equating PrEP to ARVs reduced uptake. Furthermore, failure to make a clear distinction between oral PrEP and ARVs resulted in accusations of lying, denialism, and deception leveled at users of PrEP by FSWs using ARVs, and sometimes by clients and intimate partners. FSWs using PrEP reported feeling stigmatized and thrust into interpersonal conflict with their peers after choosing PrEP, leading to broken relationships, and some resorting to taking PrEP privately or discontinuing PrEP altogether.

Conclusion

Pre-exposure prophylaxis as an ARV targeted for the prevention of HIV among high-risk groups was found to be stigmatizing. The distinctive use of PrEP and ARVs should be correctly explained to users to minimize confusion, enable differentiation and reduce interpersonal conflict. Cohesion among sex work organizations and public health care facilities is needed to disseminate the correct knowledge on PrEP. A non-stigmatizing approach to the distribution of PrEP may serve to increase uptake and adherence.

"I expected little, although I learned a lot": perceived benefits of participating in HIV risk reduction sessions among women engaged in sex work in Uganda

BACKGROUND

The global HIV burden remains a public health concern. Women engaged in sex work (WESW) are at higher risk of acquiring HIV compared to the general adult population. Uganda reports high rates of HIV prevalence among WESW. While WESW in Uganda have long been the subject of surveillance studies, they have not been targeted by theory-informed HIV prevention intervention approaches. In this study, we explored the perceived benefits of an evidence-based HIV risk reduction intervention that was implemented as part of a combination intervention tested in a clinical trial in Uganda.

METHODS

As part of a larger randomized clinical trial, we conducted semi-structured in-depth interviews with 20 WESW selected using a stratified purposive sampling. All interviews were conducted in Luganda, language spoken in the study area, and audio-recorded. They were transcribed verbatim and translated to English. Thematic analysis was used to analyze the data.

RESULTS

WESW's narratives focused on: (1) condom use; (2) alcohol/drug consumption; (3) PrEP use; (4) "handling" customers; and (5) "massaging" customers. WESW agreed that male condom was one of the important learning points for them and planned to continue using them while female condoms were received with mixed reactions. Many women appreciated receiving information about the risks of consuming alcohol and drugs, and discussed how they reduced/ eliminated their consumption. PrEP information was appreciated though identified by fewer WESW. Handling a client was discussed as a helpful strategy for safer sex through improved ability to convince customers to use condoms or avoiding sex. Massaging was also beneficial to avoid penetrative sex, but similar to female condom, massaging also yielded mixed perceptions.

CONCLUSION

WESW found the intervention beneficial and described ways in which it improved their ability to engage in safer sex and stay healthy. The fact that WESW identified other strategies beyond condom use as helpful underlines the importance of adopting a comprehensive approach to behavioral interventions targeting HIV prevention even when combined with other interventions. Additionally, WESW's narratives suggest that incorporating the tenets of social cognitive theory and harm reduction approaches in HIV prevention among this population can result in risk behavior change.

Family planning use and correlates among female sex workers in a community empowerment HIV prevention intervention in Iringa, Tanzania: a case for tailored programming

BACKGROUND

Female sex workers in sub-Saharan Africa face high unmet need for family planning and higher risk for unintended pregnancy. Community empowerment HIV prevention approaches have the potential to increase family planning uptake and present an opportunity to integrate HIV, reproductive health, and contraception. This article describes family planning use and pregnancy among female sex workers in Iringa, Tanzania and evaluates whether engagement in a community empowerment HIV prevention program is associated with contraceptive use.

METHODS

This study consists of secondary analysis from a two-community randomized controlled trial following a longitudinal cohort over 18 months. We implemented a year-long community empowerment intervention consisting of 1) a community-led drop-in-center; 2) venue-based peer education, condom distribution, and HIV testing; 3) peer service navigation; 4) sensitivity trainings for providers and police; and 5) text messages to promote engagement. Additionally, monthly seminars were held at the drop-in-center, one of which focused on family planning. Modified Poisson regression models were used to estimate the association between program exposure and family planning use in the intervention arm. (Trials Registration NCT02281578, Nov 2, 2014.) RESULTS: Among the 339 participants with follow-up data on family planning, 60% reported current family planning use; 6% reported dual use of modern contraception and condoms; over 90% had living children; and 85% sought antenatal care at their most recent pregnancy. Among the 185 participants in the intervention arm, the adjusted relative risk (aRR) of family planning use among female sex workers who reported ever attending the Shikamana drop-in-center and among female sex workers who reported attending a family planning-related workshop was respectively 26% (aRR 1.26 [95% Confidence Interval (CI): 1.02-1.56]) and 36% (aRR 1.36 [95%CI: 1.13-1.64) higher than among those who had not attended.

CONCLUSION

There is a clear need for family planning among this population. General program exposure and exposure to a family planning workshop were associated with higher family planning use, which suggests that community empowerment models have potential to increase family planning uptake for this vulnerable group.

Cumulative Effects of Adding a Small Group Intervention to Social Network Testing on HIV Testing Rates Among Crack Users in San Salvador, El Salvador

The present study evaluates a combination prevention intervention for crack users in San Salvador, El Salvador that included social network HIV testing, community events and small group interventions. We examined the cumulative effects of the social network HIV testing and small group interventions on rates of HIV testing, beyond the increase that we saw with the introduction of the social network HIV testing intervention alone. HIV test data was converted into the number of daily tests and analyzed the immediate and overtime impact of small group interventions during and in the twelve weeks after the small group intervention. The addition of the small group interventions to the baseline of monthly HIV tests resulted in increased rates of testing lasting 7 days after the small group interventions suggesting a reinforcing effect of small group interventions on testing rates.

Strategies to promote the meaningful involvement of sex workers in HIV prevention and care

PURPOSE OF REVIEW

We review the recent evidence regarding strategies for engaging sex workers in HIV prevention and care programs. We searched Pub Med on 19 March 2019 using terms 'Sex Work' And 'HIV infections'. Our search was limited to articles published since 2017.

RECENT FINDINGS

Community empowerment approaches where sex workers work collaboratively to address their specific priorities and concerns, including those beyond HIV, are those most likely to meaningfully engage sex workers. Community-driven programs that combine structural, behavioral and biomedical approaches can facilitate improved HIV outcomes by tackling barriers to uptake and retention of services along all steps in the prevention and care cascades. Microplanning, network-based recruitment and mobile-phone interventions can also help reach and support sex workers to mobilize and to engage with a range of services. Sex worker-led groups and initiatives including economic strengthening and community drug refill groups can both build social cohesion and address structural barriers to HIV outcomes including financial insecurity. Interventions which focus narrowly on increasing uptake of specific steps in prevention and care cascades outside the context of broader community empowerment responses are likely to be less effective.

SUMMARY

Comprehensive, community-driven approaches where sex workers mobilize to address their structural, behavioral and biomedical priorities work across HIV prevention and treatment cascades to increase uptake of and engagement with prevention and care technologies and promote broader health and human rights. These interventions need to be adequately supported and taken to scale.

High prevalence of non-communicable diseases among key populations enrolled at a large HIV prevention & treatment program in Kenya

INTRODUCTION

People Living with HIV (PLHIV) bear a disproportionate burden of non-communicable diseases (NCDs). Despite their significant toll across populations globally, the NCD burden among key populations (KP) in Kenya remains unknown. The burden of four NCD-categories (cardiovascular diseases, cancer, chronic respiratory diseases and diabetes) was evaluated among female sex workers (FSWs) and men who have sex with men (MSM) at the Sex Workers Outreach Program (SWOP) clinics in Nairobi Kenya.

METHODS

A retrospective medical chart review was conducted at the SWOP clinics among KP clients ≥15 years living with HIV enrolled between October 1, 2012 and September 30, 2015. The prevalence of the four NCD-categories were assessed at enrollment and during subsequent routine quarterly follow-up care visits as per the Ministry of Health guidelines. Prevalence at enrollment was determined and distributions of co-morbidities assessed using Chi-square and t-tests as appropriate during follow-up visits. Univariate and multivariate analysis were conducted to identify factors associated with NCD diagnoses.

RESULTS

Overall, 1,478 individuals' records were analyzed; 1,392 (94.2%) were from FSWs while 86 (5.8%) were from MSM over the three-year period. FSWs' median age was 35.3 years (interquartile range (IQR) 30.1-41.6) while MSM were younger at 26.8 years (IQR 23.2-32.1). At enrollment into the HIV care program, most KPs (86.6%) were at an early WHO clinical stage (stage I-II) and 1462 (98.9%) were on first-line anti-retroviral therapy (ART). A total of 271, 18.3% (95% CI: 16.4-20.4%), KPs living with HIV had an NCD diagnosis in their clinical chart records during the study period. Majority of these cases, 258 (95.2%) were noted among FSWs. Cardiovascular disease that included hypertension was present in 249/271, 91.8%, of KPs with a documented NCD. Using a proxy of two or more elevated blood pressure readings taken < 12 months apart, prevalence of hypertension rose from 1.0% (95% CI: 0.6-1.7) that was documented in the charts during the first year to 16.3% (95% CI: 14.4-18.3) in the third year. Chronic respiratory disease mainly asthma was present in 16/271, a prevalence of 1.1% (95% CI: 0.6-1.8) in the study population. Cancer in general was detected in 10/271, prevalence of 0.7% (95% CI: 0.3-1.2) over the same period. Interestingly, diabetes was not noted in the study group. Lastly, significant associations between NCD diagnosis with increasing age, body-mass index and CD4 + cell-counts were noted in univariate analysis. However, except for categories of ≥ BMI 30 kg/m2 and age ≥ 45, the associations were not sustained in adjusted risk estimates.

CONCLUSION

In Kenya, KP living with HIV and on ART have a high prevalence of NCD diagnoses. Multiple NCD risk factors were also noted against a backdrop of a changing HIV epidemic in the study population. This calls for scaling up focus on both HIV and NCD prevention and care in targeted populations at increased risk of HIV acquisition and transmission. Hence, KP programs could include integrated HIV-NCD screening and care in their guidelines.

Integrating Economic Evaluation and Implementation Science to Advance the Global HIV Response

BACKGROUND

Numerous cost-effectiveness analyses have indicated good value for money from a wide array of interventions for treatment and prevention of HIV/AIDS. There is limited evidence, however, regarding how cost-effectiveness information contributes to better decision-making around investment and action in the global HIV response.

METHODS

We review challenges for economic evaluation relevant to the global HIV response and consider how the practice of cost-effectiveness analysis could integrate approaches and insights from implementation science to enhance the impact and efficiency of HIV investments.

RESULTS

In light of signals that cost-effectiveness analyses may be vulnerable to systematic bias toward overly optimistic conclusions, we emphasize two priorities for advancing the field of economic evaluation in HIV/AIDS and more broadly in global health: (1) systematic reevaluation of the cost-effectiveness literature with reference to ex-post empirical evidence on costs and effects in real-world programs and (2) development and adoption of good-practice guidelines for incorporating implementation and delivery aspects into economic evaluations. Toward the latter aim, we propose an integrative approach that focuses on comparative evaluation of strategies, which specify both technologies/interventions as well as the delivery platforms, complementary interventions, and actions needed to increase coverage, quality, and uptake of those technologies/interventions. Specific recommendations draw on several existing implementation science models that provide systematic frameworks for understanding implementation barriers and enablers, designing and choosing specific implementation and policy actions, and evaluating outcomes.

DISCUSSION

These preliminary steps aimed at bridging the divide between economic evaluation and implementation science can help to advance the practice of economic evaluation toward a science of comparative strategy evaluation.

Missed Study Visits and Subsequent HIV Incidence Among Women in a Predominantly Sex Worker Cohort Attending a Dedicated Clinic Service in Kampala, Uganda

BACKGROUND

There is limited evidence on the relationship between sustained exposure of female sex workers (FSWs) to targeted HIV programmes and HIV incidence. We investigate the relationship between the number of missed study visits (MSVs) within each episode of 2 consecutively attended visits (MSVs) and subsequent HIV risk in a predominantly FSW cohort.

METHODS

Women at high risk of HIV are invited to attend an ongoing dedicated clinic offering a combination HIV prevention intervention in Kampala, Uganda. Study visits are scheduled once every 3 months. The analysis included HIV-seronegative women with ≥1 follow-up visit from enrollment (between April 2008 and May 2017) to August 2017. Cox regression models were fitted adjusted for characteristics on sociodemographic, reproductive, behavioral, and sexually transmitted infections (through clinical examination and serological testing for syphilis).

FINDINGS

Among 2206 participants, HIV incidence was 3.1/100 (170/5540) person-years [95% confidence interval (CI): 2.6 to 3.5]. Incidence increased from 2.6/100 person-years (95% CI: 2.1 to 3.2) in episodes without a MSV to 3.0/100 (95% CI: 2.2 to 4.1) for 1-2 MSVs and 4.3/100 (95% CI: 3.3 to 5.6) for ≥3 MSVs. Relative to episodes without a MSV, the hazard ratios (adjusted for confounding variables) were 1.40 (95% CI: 0.93 to 2.12) for 1-2 MSVs and 2.00 (95% CI: 1.35 to 2.95) for ≥3 MSVs (P-trend = 0.001).

CONCLUSION

Missing study visits was associated with increased subsequent HIV risk. Although several factors may underlie this association, the finding suggests effectiveness of targeted combination HIV prevention. But exposure to targeted interventions needs to be monitored, facilitated, and sustained in FSWs.

A Review of Pre-Exposure Prophylaxis Adherence among Female Sex Workers

Globally and in Africa specifically, female sex workers (FSWs) are at an extraordinarily high risk of contracting human immunodeficiency virus (HIV). Pre-exposure prophylaxis (PrEP) has emerged as an effective and ethical method with which to prevent HIV infection among FSWs. PrEP efficacy is, however, closely linked to adherence, and adherence to PrEP among FSWs is a complex and interrelated process that has been shown to be of importance to public health policies and HIV control and intervention programs. This comprehensive review categorizes barriers to and facilitators of adherence to HIV PrEP for FSWs, and describes five strategies for promoting PrEP adherence among FSWs. These strategies encompass 1) a long-term educational effort to decrease the stigma associated with sex work and PrEP use, 2) education on how PrEP works, 3) lifestyle modification, 4) research on next-generation PrEP products to address the inconvenience of taking daily pills, and 5) integration of PrEP into existing services, such as social services and routine primary care visits, to reduce the economic burden of seeking the medication. Our review is expected to be useful for the design of future PrEP intervention programs. Multidisciplinary intervention should be considered to promote PrEP adherence among FSWs in order to help control the HIV epidemic.

Unmet Need for Family Planning and Experience of Unintended Pregnancy Among Female Sex Workers in Urban Cameroon: Results From a National Cross-Sectional Study

Female sex workers (FSWs) in Cameroon have unmet need for effective contraception, and experience of unintended pregnancy and pregnancy termination is common. Reducing barriers to accessing high-quality, voluntary family planning services in FSW-focused community services is a key strategy to promote client-centered care, promote informed choice, reduce unintended pregnancies, and improve quality of life for FSWs.

Background:

Female sex workers (FSWs) in Cameroon commonly have unmet need for contraception posing a high risk of unintended pregnancy. Unintended pregnancy leads to a range of outcomes, and due to legal restrictions, FSWs often seek unsafe abortions. Aside from the high burden of HIV, little is known about the broader sexual and reproductive health of FSWs in Cameroon.

Methods:

From December 2015 to October 2016, we recruited FSWs aged ≥18 years through respondent-driven sampling across 5 Cameroonian cities. Cross-sectional data were collected through a behavioral questionnaire. Modified-robust Poisson regression was used to approximate adjusted prevalence ratios (aPR) for TOP and current use of effective nonbarrier contraception.

Results:

Among 2,255 FSWs (median age 28 years), 57.6% reported history of unintended pregnancy and 40.0% reported prior TOP. In multivariable analysis, TOP history was associated with current nonbarrier contraceptive use (aPR=1.23, 95% confidence interval [CI]=1.07, 1.42); ever using emergency contraception (aPR=1.34, 95% CI=1.17, 1.55); >60 clients in the past month (aPR=1.29, 95% CI= 1.07, 1.54) compared to ≤30; inconsistent condom use with clients (aPR=1.17, 95% CI=1.00, 1.37); ever experiencing physical violence (aPR=1.24, 95% CI=1.09, 1.42); and older age. Most (76.5%) women used male condoms for contraception, but only 33.2% reported consistent condom use with all partners. Overall, 26.4% of women reported currently using a nonbarrier contraceptive method, and 6.2% reported using a long-acting method. Previous TOP (aPR=1.41, 95%CI=1.16, 1.72) and ever using emergency contraception (aPR=2.70, 95% CI=2.23, 3.26) were associated with higher nonbarrier contraceptive use. Recent receipt of HIV information (aPR=0.72, 95% CI=0.59, 0.89) and membership in an FSW community-based organization (aPR=0.73, 95% CI=0.57, 0.92) were associated with lower use nonbarrier contraceptive use.

Conclusions:

Experience of unintended pregnancies and TOP is common among FSWs in Cameroon. Given the low use of nonbarrier contraceptive methods and inconsistent condom use, FSWs are at risk of repeat unintended pregnancies. Improved integration of client-centered, voluntary family planning within community-led HIV services may better support the sexual and reproductive health and human rights of FSWs consistent with the United Nations Declaration of Human Rights.

What Proportion of Female Sex Workers Practise anal Intercourse and How Frequently? A Systematic Review and Meta-analysis

HIV is more efficiently acquired during receptive anal intercourse (AI) compared to vaginal intercourse (VI) and may contribute substantially to female sex workers' (FSW) high HIV burden. We aim to determine how common and frequent AI is among FSW globally. We searched PubMed, Embase and PsycINFO for studies reporting the proportion of FSW practising AI (prevalence) and/or the number of AI acts (frequency) worldwide from 01/1980 to 10/2018. We assessed the influence of participant and study characteristics on AI prevalence (e.g. continent, study year and interview method) through sub-group analysis. Of 15,830 identified studies, 131 were included. Nearly all (N = 128) reported AI prevalence and few frequency (N = 13), over various recall periods. Most studies used face-to-face interviews (N = 111). Pooled prevalences varied little by recall period (lifetime: 15.7% 95%CI 12.2-19.3%, N = 30, I2 = 99%; past month: 16.2% 95%CI 10.8-21.6%, N = 18, I2 = 99%). The pooled proportion of FSW reporting < 100% condom use tended to be non-significantly higher during AI compared to during VI (e.g. any unprotected VI: 19.1% 95%CI 1.7-36.4, N = 5 and any unprotected AI: 46.4% 95%CI 9.1-83.6, N = 5 in the past week). Across all study participants, between 2.4 and 15.9% (N = 6) of all intercourse acts (AI and VI) were anal. Neither AI prevalence nor frequency varied substantially by any participant or study characteristics. Although varied, AI among FSW is generally common, inconsistently protected with condoms and practiced sufficiently frequently to contribute substantially to HIV acquisition in this risk group. Interventions to address barriers to condom use are needed.

HIV pre-exposure prophylaxis for female sex workers: ensuring women's family planning needs are not left behind

INTRODUCTION

Female sex workers (FSWs) experience overlapping burdens of HIV, sexually transmitted infections and unintended pregnancy. Pre-exposure prophylaxis (PrEP) is highly efficacious for HIV prevention. It represents a promising strategy to reduce HIV acquisition risks among FSWs specifically given complex social and structural factors that challenge consistent condom use. However, the potential impact on unintended pregnancy has garnered little attention. We discuss the potential concerns and opportunities for PrEP to positively or negatively impact the sexual and reproductive health and rights (SRHR) of FSWs.

DISCUSSION

FSWs have high unmet need for effective contraception and unintended pregnancy is common in low- and middle-income countries. Unintended pregnancy can have enduring health and social effects for FSWs, including consequences of unsafe abortion and financial impacts affecting subsequent risk-taking. It is possible that PrEP could negatively impact condom and other contraceptive use among FSWs due to condom substitution, normalization, external pressures or PrEP provision by single-focus services. There are limited empirical data available to assess the impact of PrEP on pregnancy rates in real-life settings. However, pregnancy rates are relatively high in PrEP trials and modelling suggests a potential two-fold increase in condomless sex among FSWs on PrEP, which, given low use of non-barrier contraceptive methods, would increase rates of unintended pregnancy. Opportunities for integrating family planning with PrEP and HIV services may circumvent these concerns and support improved SRHR. Synergies between PrEP and family planning could promote uptake and maintenance for both interventions. Integrating family planning into FSW-focused community-based HIV services is likely to be the most effective model for improving access to non-barrier contraception among FSWs. However, barriers to integration, such as provider skills and training and funding mechanisms, need to be addressed.

CONCLUSIONS

As PrEP is scaled up among FSWs, there is growing impetus to consider integrating family planning services with PrEP delivery in order to better meet the diverse SRHR needs of FSWs and to prevent unintended consequences. Programme monitoring combined with research can close data gaps and mobilize adequate resources to deliver comprehensive SRHR services respectful of all women's rights.

Factors associated with HIV and syphilis infection among female sex workers in three cities in Papua New Guinea: findings from Kauntim mi tu, a biobehavioral survey

Background In this paper, factors associated with HIV and syphilis infection in three cities in Papua New Guinea are explored. Methods: Respondent-driven sampling surveys among FSW in Port Moresby, Lae, and Mt. Hagen (2016–17) were conducted. FSW who were aged ≥12 years, who were born female, who spoke English or Tok Pisin and who had sold or exchanged vaginal sex in the past 6 months were eligible to participate. Participants were interviewed face-to-face and offered rapid HIV and syphilis testing. Survey logistic procedures were used to identify factors associated with HIV and syphilis infection, including modern contraception use, physical violence and having a casual male partner. Weighted data analysis was conducted. Results: Overall, 2901 FSW (Port Moresby, 673; Lae, 709; and Mt. Hagen, 709) were enrolled in the study. HIV prevalence was 15.2% in Port Moresby, 11.9% in Lae and 19.6% in Mt. Hagen. Factors associated with HIV varied by city; for example, use of modern contraception in Port Moresby, experiences of physical violence in Lae and ever having tested for HIV in Mt. Hagen. No one variable was associated with HIV in all cities. Prevalence of syphilis infection was 7.1%, 7.0%, and 3.0% in Port Moresby, Lae, and Mt. Hagen, respectively. Factors associated with syphilis infection also varied by city and were only significant in Lae. Conclusion: The different factors associated with HIV and syphilis infection in each city highlight the complex HIV and syphilis epidemics among FSW and the importance of conducting surveys in multiple locations and developing local interventions.

Do combination HIV prevention programmes result in increased empowerment, inclusion and agency to demand equal rights for marginalised populations in low-income and middle-income countries? A systematic review

Introduction

This systematic review aims to determine if combination HIV prevention programmes include outcome measures for empowerment, inclusion and agency to demand equal rights and measure the relationship between empowerment and HIV prevention outcomes.

Methods

An electronic literature search of PubMed, POPLINE, Index Medicus and Google Scholar was conducted between August and October 2018. We included studies that evaluated combination prevention programmes that had all three types of intervention components and that specifically serve members of populations disproportionately affected by HIV published from 2008 to 2018. The selected studies were screened for inclusion, and relevant data abstracted, assessed for bias and synthesised.

Results

This review included a total of 15 studies. Findings indicate that combination HIV prevention programmes for marginalised populations have delivered a variety of theory-based behavioural and structural interventions that support improvements in empowerment, inclusion and agency. However, empowerment, inclusion and least of all agency are not measured consistently or in a standardised way. In addition, analysis of their relationships with HIV prevention outcomes is rare. Out of our 15 included studies, only two measured a relationship between an empowerment, inclusion or agency outcome and an HIV prevention outcome.

Conclusion

These findings suggest that policy-makers, programme planners and researchers might need to consider the intermediate steps on the pathway to increased condom use and HIV testing so as to explain the ‘how’ of their achievements and inform future investments in HIV prevention. This will support replication and expansion of programmes and ensure sustainability of the programmes.

A combination intervention addressing sexual risk-taking behaviors among vulnerable women in Uganda: study protocol for a cluster randomized clinical trial

BACKGROUND

Sub-Saharan Africa (SSA) has the highest number of people living with HIV/AIDS, with Nigeria, South Africa, and Uganda accounting for 48% of new infections. A systematic review of the HIV burden among women engaged in sex work (WESW) in 50 low- and middle-income countries found that they had increased odds of HIV infection relative to the general female population. Social structural factors, such as the sex work environment, violence, stigma, cultural issues, and criminalization of sex work are critical in shaping sexually transmitted infection (STI)/HIV risks among WESW and their clients in Uganda. Poverty is the most commonly cited reason for involvement in sex work in SSA. Against this backdrop, this study protocol describes a randomized controlled trial (RCT) that tests the impact of adding economic empowerment to traditional HIV risk reduction (HIVRR) to reduce new incidence of STIs and HIV among WESW in Rakai and the greater Masaka regions in Uganda.

METHODS

This three-arm RCT will evaluate the efficacy of adding savings, financial literacy and vocational training/mentorship to traditional HIVRR on reducing new incidence of STI infections among 990 WESW across 33 hotspots. The three arms (n = 330 each) are: 1) Control group: only HIVRR versus 2) Treatment group 1: HIVRR plus Savings plus Financial Literacy (HIVRR + S + FL); and 3) Treatment group 2: HIVRR plus S plus FL plus Vocational Skills Training and Mentorship (V) (HIVRR + S + FL + V). Data will be collected at baseline (pre-test), 6, 12, 18 and 24-months post-intervention initiation. This study will use an embedded experimental mixed methods design where qualitative data will be collected post-intervention across all conditions to explore participant experiences.

DISCUSSION

When WESW have access to more capital and/or alternative forms of employment and start earning formal income outside of sex work, they may be better able to improve their skills and employability for professional advancement, thereby reducing their STI/HIV risk. The study findings may advance our understanding of how best to implement gender-specific HIV prevention globally, engaging women across the HIV treatment cascade. Further, results will provide evidence for the intervention's efficacy to reduce STIs and inform implementation sustainability, including costs and cost-effectiveness.

Feasibility, acceptability and potential sustainability of a 'diagonal' approach to health services for female sex workers in Mozambique

Background

Female sex workers (FSWs) in many settings have restricted access to sexual and reproductive health (SRH) services. We therefore conducted an implementation study to test a ‘diagonal’ intervention which combined strengthening of FSW-targeted services (vertical) with making public health facilities more FSW-friendly (horizontal). We piloted it over 18 months and then assessed its performance.

Methods

Applying a convergent parallel mixed-methods design, we triangulated the results of the analysis of process indicators, semi-structured interviews with policy makers and health managers, structured interviews with health care providers and group discussions with peer outreach workers. We then formulated integrated conclusions on the interventions’ feasibility, acceptability by providers, managers and policy makers, and potential sustainability.

Results

The intervention, as designed, was considered theoretically feasible by all informants, but in practice the expansion of some of the targeted services was hampered by insufficient financial resources, institutional capacity and buy-in from local government and private partners, and could not be fully actualised. In terms of acceptability, there was broad consensus on the need to ensure FSWs have access to SRH services, but not on how this might be achieved. Targeted clinical services were no longer endorsed by national government, which now prefers a strategy of making public services more friendly for key populations. Stakeholders judged that the piloted model was not fully sustainable, nor replicable elsewhere in the country, given its dependency on short-term project-based funding, lack of government endorsement for targeted clinical services, and viewing the provision of community activities as a responsibility of civil society.

Conclusions

In the current Mozambican context, a ‘diagonal’ approach to ensure adequate access to sexual and reproductive health care for female sex workers is not fully feasible, acceptable or sustainable, because of insufficient resources and lack of endorsement by national policy makers for the targeted, vertical component.

Pre-exposure Prophylaxis: The Delivery Challenge

HIV pre-exposure prophylaxis (PrEP), despite its efficacy, has been slow in uptake throughout the world. This article discusses the operational and service delivery complexity, based on early real-world experience, with some recommendations on how this promising intervention could be made more available. Currently, access to PrEP is made complex by restricting delivery to dedicated health facilities, as well as requirements around HIV testing and toxicity monitoring. Expanding to verticalized services that focus on well-defined populations where HIV testing and treatment programmes already exist, has proven relatively simple. Providing PrEP outside of this environment has yet to be demonstrated at any scale, and will likely require innovative thinking addressing the regulatory and clinical environment, so as to ensure easier access to this promising HIV prevention tool.

The effect of mobility on HIV-related healthcare access and use for female sex workers: A systematic review

Female sex workers (FSW) experience a high HIV burden and are often mobile. FSW access to HIV-related healthcare is essential for equitable welfare and to reduce new HIV infections. We systematically reviewed the literature on mobility and HIV-related healthcare access and use among FSW. Outcome measures included: HIV/STI testing, STI treatment, PrEP (initiation or adherence), and ART (initiation or adherence). We summarised the results with a narrative synthesis. From 7417 non-duplicated citations, nine studies from Canada (3), Guatamala, Honduras (2), India, South Africa, and Vietnam were included. Only one of the studies was designed to address mobility and healthcare access, and only six reported adjusted effect estimates. Mobility was measured over four time-frames (from 'current' to 'ever'), as having lived or worked elsewhere or in another town/province/country. Three studies from Canada, Guatemala, and India found mobility associated with increased odds of poor initial access to healthcare (adjusted odds ratios (AOR) from 1.33, 95% CI 1.02, 1.75, to 2.27, 95% CI 1.09, 4.76), and one from Vietnam found no association (odds ratio (OR): 0.92, 95% CI 0.65, 1.28). The study from South Africa found no association with initiating ART (risk ratio: 0.86, 95% CI 0.65, 1.14). Two studies from Canada and Honduras found increased odds of ART interruption (AOR 2.74, 95% CI 0.89, 8.42; 5.19, 95% CI 1.38, 19.56), while two other studies from Canada and Honduras found no association with detectable viral load (OR 0.84, 95% CI 0.08, 8.33; AOR 0.79, 95% CI 0.41, 1.69). We found that mobility is associated with reduced initial healthcare access and interruption of ART, consistent with literature from the general population. Discordance between effects on adherence and viral load may be due to measurement of mobility. Future research should carefully construct measures of mobility and consider a range of HIV-related healthcare outcomes.

Impact of a "Diagonal" Intervention on Uptake of Sexual and Reproductive Health Services by Female Sex Workers in Mozambique: A Mixed-Methods Implementation Study

Background

Female sex workers (FSWs) have high risks for adverse sexual and reproductive health (SRH) outcomes, yet low access to services. Within an implementation research project enhancing uptake of SRH services by FSWs, we piloted a “diagonal” intervention, which combined strengthening of FSW-targeted services (vertical) with making public health facilities more FSW-friendly (horizontal), and tested its effect.

Methods

The study applied a convergent parallel mixed-methods design to assess changes in access to SRH services. Results of structured interviews with FSWs pre-intervention (N = 311) and thereafter (N = 404) were compared with the findings of eight post-intervention focus group discussions (FGDs) with FSWs and two with FSW-peer educators (PEs).

Results

Marked and statistically significant rises occurred in consistent condom use with all partners (55.3–67.7%), ever use of female condoms (37.9–54.5%), being tested for HIV in the past 6 months (56.0–76.6%), using contraception (84.5–95.4%), ever screened for cervical cancer (0.0–16.9%) and having ≥10 contacts with a PE in the past year (0.5–24.45%). Increases mostly resulted from FSW-targeted outreach, with no rise detected in utilization of public health facilities. FGD participants reported that some facilities had become more FSW-friendly, but barriers such as stock-outs, being asked for bribes and disrespectful treatment persisted.

Conclusion

The combination of expanding FSW-targeted SRH services with improving access to the public health services resulted in an overall increased uptake of services, but almost exclusively because of the strengthened targeted (vertical) outreach services. Utilization of public SRH services had not yet increased and many barriers to access remained. Our diagonal approach was thus only successful in its vertical component. Improving access to the general health services remains nevertheless important and further research is needed how to reduce barriers. Ideally, the combination approach should be maintained and more successful approaches to increase utilization of public services should be explored.

Intentional and Unintentional Condom Breakage and Slippage in the Sexual Interactions of Female and Male Sex Workers and Clients in Mombasa, Kenya

We examined why male condoms broke or slipped off during commercial sex and the actions taken in response among 75 female and male sex workers and male clients recruited from 18 bars/nightclubs in Mombasa, Kenya. Most participants (61/75, 81%) had experienced at least one breakage or slippage during commercial sex. Many breakages were attributed to the direct actions of clients. Breakages and slippages fell into two main groups: those that were intentionally caused by clients and unintentional ones caused by inebriation, forceful thrusting during sex and incorrect or non-lubricant use. Participant responses included: stopping sex and replacing the damaged condoms, doing nothing, getting tested for HIV, using post-exposure prophylaxis and washing. Some sex workers also employed strategies to prevent the occurrence of condom breakages. Innovative client-oriented HIV prevention and risk-reduction interventions are therefore urgently needed. Additionally, sex workers should be equipped with skills to recognize and manage breakages.
