Stigma and sex work

Editor’s notes: Two interesting studies this month looked at aspects of stigma.  There are big methodological challenges to the study of stigma.  Stigma comprises several different domains and few studies use standardized approaches to measurement that can be translated easily into other contexts.  A systematic review and meta-analysis concludes that people who feel more stigmatized are twice as likely to delay presenting for HIV care.  Gesesew HA and colleagues found only ten studies that met their pre-specified inclusion criteria, and five of these came from Ethiopia.  They acknowledge many of the challenges in combining the results of these ten studies into a single conclusion.  They recommend engagement of health care workers to try to reduce perceived stigma among people living with HIV.

The Nyblade L et al. study from Kenya emphasizes the perception of stigma among sex workers.  In a large sample of 497 females and 232 males, most reported experiencing stigma both verbal and measured from health care workers. For female sex workers, the anticipation of such stigma led to avoidance of health services for both HIV and non-HIV related conditions. In order to provide effective services for key populations, health care workers must be trained to be non-judgemental.  HIV services need to be provided in the context of an overall package of health care.

A study from Europe used ecological data to explore structural risks for HIV among sex workers.  Reeves A and colleagues used regression modelling with data on sex work policies from 27 countries.  They showed a strong correlation between criminalisation of sex work and higher prevalence of HIV among sex workers.  Although they included other factors such as the level of economic development and using drugs, the relatively small number of data points does mean that there may be other confounding factors that could not be measured or adjusted for.

Significant association between perceived HIV related stigma and late presentation for HIV/AIDS care in low and middle-income countries: A systematic review and meta-analysis.

Gesesew HA, Tesfay Gebremedhin A, Demissie TD, Kerie MW, Sudhakar M, Mwanri L. PLoS One. 2017 Mar 30;12(3):e0173928. doi: 10.1371/journal.pone.0173928.eCollection 2017.

Background: Late presentation for human immunodeficiency virus (HIV) care is a major impediment for the success of antiretroviral therapy (ART) outcomes. The role that stigma plays as a potential barrier to timely diagnosis and treatment of HIV among people living with HIV/AIDS (acquired immunodeficiency syndrome) is ambivalent. This review aimed to assess the best available evidence regarding the association between perceived HIV related stigma and time to present for HIV/AIDS care.

Methods: Quantitative studies conducted in English language between 2002 and 2016 that evaluated the association between HIV related stigma and late presentation for HIV care were sought across four major databases. This review considered studies that included the following outcome: 'late HIV testing', 'late HIV diagnosis' and 'late presentation for HIV care after testing'. Data were extracted using a standardized Joanna Briggs Institute (JBI) data extraction tool. Meta- analysis was undertaken using Revman-5 software. I2 and chi-square test were used to assess heterogeneity. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals and corresponding p-value.

Results: Ten studies from low- and middle- income countries met the search criteria, including six (6) and four (4) case control studies and cross-sectional studies respectively. The total sample size in the included studies was 3788 participants. Half (5) of the studies reported a significant association between stigma and late presentation for HIV care. The meta-analytical association showed that people who perceived high HIV related stigma had two times more probability of late presentation for HIV care than who perceived low stigma (pooled odds ratio = 2.4; 95%CI: 1.6-3.6, I2 = 79%).

Conclusions: High perceptions of HIV related stigma influenced timely presentation for HIV care. In order to avoid late HIV care presentation due the fear of stigma among patients, health professionals should play a key role in informing and counselling patients on the benefits of early HIV testing or early entry to HIV care. Additionally, linking the systems and positive case tracing after HIV testing should be strengthened.

The relationship between health worker stigma and uptake of HIV counseling and testing and utilization of non-HIV health services: the experience of male and female sex workers in Kenya.

Nyblade L, Reddy A, Mbote D, Kraemer J, Stockton M, Kemunto C, Krotki K, Morla J, Njuguna S, Dutta A, Barker C. AIDS Care. 2017 Mar 22:1-9. doi: 10.1080/09540121.2017.1307922. [Epub ahead of print]

The barrier HIV-stigma presents to the HIV treatment cascade is increasingly documented; however less is known about female and male sex worker engagement in and the influence of sex-work stigma on the HIV care continuum. While stigma occurs in all spheres of life, stigma within health services may be particularly detrimental to health seeking behaviors. Therefore, we present levels of sex-work stigma from healthcare workers (HCW) among male and female sex workers in Kenya, and explore the relationship between sex-work stigma and HIV counseling and testing. We also examine the relationship between sex-work stigma and utilization of non-HIV health services. A snowball sample of 497 female sex workers (FSW) and 232 male sex workers (MSW) across four sites was recruited through a modified respondent-driven sampling process. About 50% of both male and female sex workers reported anticipating verbal stigma from HCW while 72% of FSW and 54% of MSW reported experiencing at least one of seven measured forms of stigma from HCW. In general, stigma led to higher odds of reporting delay or avoidance of counseling and testing, as well as non-HIV specific services. Statistical significance of relationships varied across type of health service, type of stigma and gender. For example, anticipated stigma was not a significant predictor of delay or avoidance of health services for MSW; however, FSW who anticipated HCW stigma had significantly higher odds of avoiding (OR = 2.11) non-HIV services, compared to FSW who did not. This paper adds to the growing evidence of stigma as a roadblock in the HIV treatment cascade, as well as its undermining of the human right to health. While more attention is being paid to addressing HIV-stigma, it is equally important to address the key population stigma that often intersects with HIV-stigma.

National sex work policy and HIV prevalence among sex workers: an ecological regression analysis of 27 European countries.

Reeves A, Steele S, Stuckler D, McKee M, Amato-Gauci A, Semenza JC. Lancet HIV. 2017 Mar;4(3):e134-e140. doi: 10.1016/S2352-3018(16)30217-X. Epub2017 Jan 25.

Background: Sex workers are disproportionately affected by HIV compared with the general population. Most studies of HIV risk among sex workers have focused on individual-level risk factors, with few studies assessing potential structural determinants of HIV risk. In this Article, we examine whether criminal laws around sex work are associated with HIV prevalence among female sex workers.

Method: We estimate cross-sectional, ecological regression models with data from 27 European countries on HIV prevalence among sex workers from the European Centre for Disease Control; sex-work legislation from the US State Department's Country Reports on Human Rights Practices and country-specific legal documents; the rule of law and gross-domestic product per capita, adjusted for purchasing power, from the World Bank; and the prevalence of injecting drug use among sex workers. Although data from two countries include male sex workers, the numbers are so small that the findings here essentially pertain to prevalence in female sex workers.

Findings: Countries that have legalised some aspects of sex work (n=17) have significantly lower HIV prevalence among sex workers than countries that criminalise all aspects of sex work (n=10; β=-2·09, 95% CI -0·80 to -3·37;p=0·003), even after controlling for the level of economic development (β=-1·86; p=0·038) and the proportion of sex workers who are injecting drug users (-1·93;p=0·026). We found that the relation between sex work policy and HIV among sex workers might be partly moderated by the effectiveness and fairness of enforcement, suggesting legalisation of some aspects of sex work could reduce HIV among sex workers to the greatest extent in countries where enforcement is fair and effective.

Interpretation: Our findings suggest that the legalisation of some aspects of sex work might help reduce HIV prevalence in this high-risk group, particularly in countries where the judiciary is effective and fair.

The effects of trauma follow people on the move

A systematic review of HIV risk behaviors and trauma among forced and unforced migrant populations from low and middle-income countries: state of the literature and future directions.

Michalopoulos LM, Aifah A, El-Bassel N. AIDS Behav. 2016 Feb;20(2):243-61. doi: 10.1007/s10461-015-1014-1.

The aim of the current systematic review is to examine the relationship between trauma and HIV risk behaviors among both forced and unforced migrant populations from low and middle income countries (LMIC). We conducted a review of studies published from 1995 to 2014. Data were extracted related to (1) the relationship between trauma and HIV risk behaviors, (2) methodological approach, (3) assessment methods, and (4) differences noted between forced and unforced migrants. A total of 340 records were retrieved with 24 studies meeting inclusion criteria. Our review demonstrated an overall relationship between trauma and HIV risk behaviors among migrant populations in LMIC, specifically with sexual violence and sexual risk behavior. However, findings from 10 studies were not in full support of the relationship. Findings from the review suggest that additional research using more rigorous methods is critically needed to understand the nature of the relationship experienced by this key-affected population.

Editor’s notes: The number of forced and unforced migrants is growing globally. Refugees, asylum seekers, and internally displaced persons (IDP) are forced migrants who often migrate due to political violence or conflict. Labour migrants are seen as unforced migrants who choose to emigrate for economic reasons. About half of labour migrants worldwide are women who are increasingly migrating on their own being the sole income provider for their families. With respect to trauma exposure and HIV risk in settings of long-term political violence and conflict, the distinction between war migrant, non-war migrant, and long-term resident is blurred. This in-depth review of 24 studies related to low-and middle-income countries (LMIC), mostly from sub-Saharan Africa, found findings similar to those from non-migrant populations in high-income countries. These linked traumatic experiences among migrant populations with HIV risk behaviours. Sexual violence was consistently associated with HIV sexual risk behaviours and HIV infection across the studies. But there are big gaps in the scientific literature. For example, the relationship between trauma and HIV risks has been explored for female labour migrants who are sex workers but not among women who have other occupations. Most studies addressed sexual risk and alcohol dependence, but injecting drug risk behaviours and use of any illicit drugs were virtually ignored by most studies. Few studies examined a possible link for trauma that occurred pre-migration and post-migration. Three qualitative studies examined male migrants who have sex with men, finding that violent experiences and discrimination and stigma associated with homophobia, combined with other migrant-associated traumas, can compound their mental health outcomes and subsequent HIV risk behaviours – but all were only conducted in the last four years. No studies were found that focused on HIV prevention programmes to address trauma and HIV risks among migrant workers in LMIC. However, the studies do reveal important factors that prevention programmes would have to consider. For example, concerns among labour migrants about dangerous working conditions may take precedence over HIV risk perceptions and the need for safer sex. This systematic review presents a wealth of information while highlighting the need to improve the quality of scientific research examining the link between HIV and trauma among both forced and unforced migrants in LMIC.

Violence experience of women living with HIV: a global study

Violence. Enough already: findings from a global participatory survey among women living with HIV.

Orza L, Bewley S, Chung C, Crone ET, Nagadya H, Vazquez M, Welbourn A. J Int AIDS Soc. 2015 Dec 1;18(6 Suppl 5):20285. doi: 10.7448/IAS.18.6.20285. eCollection 2015.

Introduction: Women living with HIV are vulnerable to gender-based violence (GBV) before and after diagnosis, in multiple settings. This study's aim was to explore how GBV is experienced by women living with HIV, how this affects women's sexual and reproductive health (SRH) and human rights (HR), and the implications for policymakers.

Methods: A community-based, participatory, user-led, mixed-methods study was conducted, with women living with HIV from key affected populations. Simple descriptive frequencies were used for quantitative data. Thematic coding of open qualitative responses was performed and validated with key respondents.

Results: In total, 945 women living with HIV from 94 countries participated in the study. Eighty-nine percent of 480 respondents to an optional section on GBV reported having experienced or feared violence, either before, since and/or because of their HIV diagnosis. GBV reporting was higher after HIV diagnosis (intimate partner, family/neighbours, community and health settings). Women described a complex and iterative relationship between GBV and HIV occurring throughout their lives, including breaches of confidentiality and lack of SRH choice in healthcare settings, forced/coerced treatments, HR abuses, moralistic and judgemental attitudes (including towards women from key populations), and fear of losing child custody. Respondents recommended healthcare practitioners and policymakers address stigma and discrimination, training, awareness-raising, and HR abuses in healthcare settings.

Conclusions: Respondents reported increased GBV with partners and in families, communities and healthcare settings after their HIV diagnosis and across the life-cycle. Measures of GBV must be sought and monitored, particularly within healthcare settings that should be safe. Respondents offered policymakers a comprehensive range of recommendations to achieve their SRH and HR goals. Global guidance documents and policies are more likely to succeed for the end-users if lived experiences are used.

Abstract  Full-text [free] access

Editor’s notes: Violence against women who are living with HIV is common globally. This paper reports on a study of 832 women living with HIV from 94 countries who participated in an online survey, recruited through a non-random snowball sampling model. The survey comprised quantitative and qualitative (free text) components. Participants included women who had ever or were currently using injection drugs (14%), who had ever or were currently selling sex (14%), and who had ever or were currently homeless (14%). Lifetime experience of violence among respondents was high (86%). Perpetrators included: intimate partner (59%), family member / neighbour (45%), community member (53%), health care workers (53%) and police, military, prison or detention services (17%). Findings suggest that violence is not a one off occurrence and cannot easily be packaged as a cause or a consequence of HIV. Instead violence occurs throughout women’s lives, takes multiple forms, and has a complex and iterative relationship with HIV.

The study population did not represent all women living with HIV, and was biased towards women with internet access who have an activist interest. Nonetheless, the study provides further evidence of the breadth and frequency of gender based violence experienced by women living with HIV. Key recommendations for policy makers include training of health care workers working in sexual and reproductive services to offer non-discriminatory services to women living with HIV and to effectively respond to disclosures of gender based violence (such as intimate partner violence) as part of the package of care.

Expanding ART access: increasing costs

The HIV treatment gap: estimates of the financial resources needed versus available for scale-up of antiretroviral therapy in 97 countries from 2015 to 2020.

Dutta A, Barker C, Kallarakal A. PLoS Med. 2015 Nov 24;12(11):e1001907. doi: 10.1371/journal.pmed.1001907. eCollection 2015.

Background: The World Health Organization (WHO) released revised guidelines in 2015 recommending that all people living with HIV, regardless of CD4 count, initiate antiretroviral therapy (ART) upon diagnosis. However, few studies have projected the global resources needed for rapid scale-up of ART. Under the Health Policy Project, we conducted modeling analyses for 97 countries to estimate eligibility for and numbers on ART from 2015 to 2020, along with the facility-level financial resources required. We compared the estimated financial requirements to estimated funding available.

Methods and findings: Current coverage levels and future need for treatment were based on country-specific epidemiological and demographic data. Simulated annual numbers of individuals on treatment were derived from three scenarios: (1) continuation of countries' current policies of eligibility for ART, (2) universal adoption of aspects of the WHO 2013 eligibility guidelines, and (3) expanded eligibility as per the WHO 2015 guidelines and meeting the Joint United Nations Programme on HIV/AIDS "90-90-90" ART targets. We modeled uncertainty in the annual resource requirements for antiretroviral drugs, laboratory tests, and facility-level personnel and overhead.

We estimate that 25.7 (95% CI 25.5, 26.0) million adults and 1.57 (95% CI 1.55, 1.60) million children could receive ART by 2020 if countries maintain current eligibility plans and increase coverage based on historical rates, which may be ambitious. If countries uniformly adopt aspects of the WHO 2013 guidelines, 26.5 (95% CI 26.0 27.0) million adults and 1.53 (95% CI 1.52, 1.55) million children could be on ART by 2020. Under the 90-90-90 scenario, 30.4 (95% CI 30.1, 30.7) million adults and 1.68 (95% CI 1.63, 1.73) million children could receive treatment by 2020. The facility-level financial resources needed for scaling up ART in these countries from 2015 to 2020 are estimated to be US$45.8 (95% CI 45.4, 46.2) billion under the current scenario, US$48.7 (95% CI 47.8, 49.6) billion under the WHO 2013 scenario, and US$52.5 (95% CI 51.4, 53.6) billion under the 90-90-90 scenario. After projecting recent external and domestic funding trends, the estimated 6-y financing gap ranges from US$19.8 billion to US$25.0 billion, depending on the costing scenario and the U.S. President's Emergency Plan for AIDS Relief contribution level, with the gap for ART commodities alone ranging from US$14.0 to US$16.8 billion. The study is limited by excluding above-facility and other costs essential to ART service delivery and by the availability and quality of country- and region-specific data.

Conclusions: The projected number of people receiving ART across three scenarios suggests that countries are unlikely to meet the 90-90-90 treatment target (81% of people living with HIV on ART by 2020) unless they adopt a test-and-offer approach and increase ART coverage. Our results suggest that future resource needs for ART scale-up are smaller than stated elsewhere but still significantly threaten the sustainability of the global HIV response without additional resource mobilization from domestic or innovative financing sources or efficiency gains. As the world moves towards adopting the WHO 2015 guidelines, advances in technology, including the introduction of lower-cost, highly effective antiretroviral regimens, whose value are assessed here, may prove to be "game changers" that allow more people to be on ART with the resources available.

Abstract Full-text [free] access

Editor’s notes: This is a complex and important paper that seeks to understand the financial requirements necessary to: a) continue countries’ current policies of eligibility for ART, b) roll out universal adoption of certain aspects of WHO 2013 eligibility guidelines, and c) expand eligibility as per WHO 2015 guidelines and meeting the Joint United Nations Programme on HIV/AIDS ‘90-90-90’ targets.

The authors estimated the number of adults and children eligible for and receiving HIV treatment, as well as the cost of providing ART in 97 countries across six regions, covering different income levels. They estimated that 25.7 million adults and 1.57 million children could receive ART by 2020 if countries maintain the current eligibility strategies. If countries adopted WHO 2013 eligibility guidelines, 26.5 million adults and 1.53 million children would be on ART by 2020, and if they adopted the 90-90-90 scenario, 30.4 million adults and 1.68 million children could receive treatment by then. The financial resources necessary for this scale up are estimated to be US$ 45.8 billion under current eligibility, US$ 48.7 billion under WHO 2013 scenario and US$ 52.5 billion under the 90-90-90 scenario. The estimated funding gap for the six year period ranges between US$ 20 and US$ 25 billion. In this study, the costs of commodities were taken directly from data collated by other organisations.  No empirical cost estimates of service delivery were made.  Nor was there an attempt to understand the cost implications of the development synergies and social and programme enablers that may be needed to increase the number of people living with HIV knowing their status.  The new WHO recommendations need to be actively pursued if we are to meet targets, rather than passively continuing with “business as usual”. 

Nonetheless, the findings of this study highlight the gap between guidelines written by WHO and very real programmatic obstacles on the ground. There is evidence to suggest that universal test-and-treat strategies could lead to substantially improved health outcomes at the population level, as well as potentially being cost-saving in the long-term. However, as the authors have illustrated, it would require increased levels of funding. What needs to be explored further now is how to overcome the logistical hurdles of rolling out such an initiative. Changing systems and practices is costly and takes time. Health workers will have to be retrained, data collection strategies will have to be revised. Expanding treatment may also mean increasing the number of health staff working on this initiative, which has an opportunity cost that may reverberate in other parts of the health system. Substantially altering health service provision, particularly in weak health systems, may have knock-on effects with unexpected and unintended consequences.

WHO guidelines serve a vital purpose of giving us a goal to aim for. But studies like this one help us know if and how we can get there.

Combination harm reduction may be more effective and cost-effective than partial approaches alone

The cost-effectiveness of harm reduction.

Wilson DP, Donald B, Shattock AJ, Wilson D, Fraser-Hurt N. Int J Drug Policy. 2015 Feb;26 Suppl 1:S5-11. doi: 10.1016/j.drugpo.2014.11.007. Epub 2014 Dec 1.

HIV prevalence worldwide among people who inject drugs (PWID) is around 19%. Harm reduction for PWID includes needle-syringe programs (NSPs) and opioid substitution therapy (OST) but often coupled with antiretroviral therapy (ART) for people living with HIV. Numerous studies have examined the effectiveness of each harm reduction strategy. This commentary discusses the evidence of effectiveness of the packages of harm reduction services and their cost-effectiveness with respect to HIV-related outcomes as well as estimate resources required to meet global and regional coverage targets. NSPs have been shown to be safe and very effective in reducing HIV transmission in diverse settings; there are many historical and very recent examples in diverse settings where the absence of, or reduction in, NSPs have resulted in exploding HIV epidemics compared to controlled epidemics with NSP implementation. NSPs are relatively inexpensive to implement and highly cost-effective according to commonly used willingness-to-pay thresholds. There is strong evidence that substitution therapy is effective, reducing the risk of HIV acquisition by 54% on average among PWID. OST is relatively expensive to implement when only HIV outcomes are considered; other societal benefits substantially improve the cost-effectiveness ratios to be highly favourable. Many studies have shown that ART is cost-effective for keeping people alive but there is only weak supportive, but growing evidence, of the additional effectiveness and cost-effectiveness of ART as prevention among PWID. Packages of combined harm reduction approaches are highly likely to be more effective and cost-effective than partial approaches. The coverage of harm reduction programs remains extremely low across the world. The total annual costs of scaling up each of the harm reduction strategies from current coverage levels, by region, to meet WHO guideline coverage targets are high with ART greatest, followed by OST and then NSPs. But scale-up of all three approaches is essential. These interventions can be cost-effective by most thresholds in the short-term and cost-saving in the long-term.

Abstract   Full-text [free] access

Editor’s notes: The spread of HIV among people who inject drugs has driven epidemics throughout regions of eastern Europe, and central and South-East Asia. In eastern Europe and central Asia, the majority of HIV infections have been attributed to injecting drug use. Some countries in the Middle East and North Africa region have also been experiencing rapidly emerging HIV epidemics among people who inject drugs. Harm reduction refers to methods of reducing health risks when eliminating them may not be possible. This paper provides a comprehensive review of evidence on the effectiveness and cost-effectiveness of different harm reduction approaches. These include needle- syringe programmes, opioid substitution therapy (OST), and antiretroviral therapy (ART), when implemented in different settings. Importantly, alongside considering the potential benefits of each approach separately, it makes the case that combination  prevention strategies are synergistic, and may achieve multiple impacts. Sadly still however, the coverage of harm reduction remains very low across the world. An estimated 90% of people who inject drugs worldwide are not accessing needle-syringe programmes, despite this being a highly effective and cost-effective programme. Along with the need for a greater investment in harm reduction, there are socio-political and legislative reasons for poor coverage of harm reduction. This cannot be improved without first addressing the stigma, discrimination and intolerance that restricts the expansion of harm reduction programmes in many settings. Addressing these barriers remains of paramount importance for facilitating effective harm reduction programmes. Encouragingly however, high OST coverage has been reported in Iran, Czech Republic and western Europe, and several countries in Asia and the Middle East have begun to scale-up their programmes. China has recently had the largest OST scale-up programme in the world. Uptake of ART by people living with HIV who inject drugs illustrates the largest disparities with what is required or deemed to be appropriate access. Only 14% of people living with HIV who inject drugs globally, have access to ART, with the largest gaps in ART provision in eastern Europe and central Asia. The further expansion of harm reduction is urgently needed, both to meet WHO targets, and to achieve the UNAIDS 90-90-90 target.
