You are wasting our drugs: health service barriers to HIV treatment for sex workers in Zimbabwe

BackgroundAlthough disproportionately affected by HIV, sex workers (SWs) remain neglected by efforts to expand access to antiretroviral treatment (ART). In Zimbabwe, despite the existence of well-attended services targeted to female SWs, fewer than half of women diagnosed with HIV took up referrals for assessment and ART initiation; just 14% attended more than one appointment. We conducted a qualitative study to explore the reasons for non-attendance and the high rate of attrition.MethodsThree focus group discussions (FGD) were conducted in Harare with HIV-positive SWs referred from the ‘Sisters with a Voice’ programme to a public HIV clinic for ART eligibility screening and enrolment. Focus groups explored SWs’ experiences and perceptions of seeking care, with a focus on how managing HIV interacted with challenges specific to being a sex worker. FGD transcripts were analyzed by identifying emerging and recurring themes that were specifically related to interactions with health services and how these affected decision-making around HIV treatment uptake and retention in care.ResultsSWs emphasised supply-side barriers, such as being demeaned and humiliated by health workers, reflecting broader social stigma surrounding their work. Sex workers were particularly sensitive to being identified and belittled within the health care environment. Demand-side barriers also featured, including competing time commitments and costs of transport and some treatment, reflecting SWs’ marginalised socio-economic position.ConclusionImproving treatment access for SWs is critical for their own health, programme equity, and public health benefit. Programmes working to reduce SW attrition from HIV care need to proactively address the quality and environment of public services. Sensitising health workers through specialised training, refining referral systems from sex-worker friendly clinics into the national system, and providing opportunities for SW to collectively organise for improved treatment and rights might help alleviate the barriers to treatment initiation and attention currently faced by SW.

Engagement with HIV prevention treatment and care among female sex workers in Zimbabwe: a respondent driven sampling survey.

Objective(S) To determine the HIV prevalence and extent of engagement with HIV prevention and care among a representative sample of Zimbabwean sex workers working in Victoria Falls, Hwange and Mutare. Design Respondent driven sampling (RDS) surveys conducted at each site. Methods Sex workers were recruited using respondent driven sampling with each respondent limited to recruiting 2 peers. Participants completed an interviewer-administered questionnaire and provided a finger prick blood sample for HIV antibody testing. Statistical analysis took account of sampling method. Results 870 women were recruited from the three sites. HIV prevalence was between 50 and 70%. Around half of those confirmed HIV positive were aware of their HIV status and of those 50-70% reported being enrolled in HIV care programmes. Overall only 25-35% of those with laboratory-confirmed HIV were accessing antiretroviral therapy. Among those reporting they were HIV negative, 21-28% reported having an HIV test in the last 6 months. Of those tested HIV negative, most (65-82%) were unaware of their status. Around two-thirds of sex workers reported consistent condom use with their clients. As in other settings, sex workers reported high rates of gender based violence and police harassment. Conclusions This survey suggests that prevalence of HIV is high among sex workers in Zimbabwe and that their engagement with prevention, treatment and care is sub-optimal. Intensifying prevention and care interventions for sex workers has the potential to markedly reduce HIV and social risks for sex workers, their clients and the general population in Zimbabwe and elsewhere in the region.

Intimate partner violence and condom and diaphragm nonadherence among women in an HIV prevention trial in southern Africa.

Background:We longitudinally examined the effect of intimate partner violence (IPV) on condom and diaphragm nonadherence among women in the Methods for Improving Reproductive Health in Africa study, a phase III HIV prevention trial in southern Africa. Methods:Recent IPV (fear of violence, emotional abuse, physical violence, or forced sex, in past 3 months), condom nonadherence, and diaphragm nonadherence were assessed at baseline, 12 month, and exit visits (up to 24 months). The association between IPV and (1) condom nonadherence or (2) diaphragm nonadherence across visits was modeled using Generalized Estimating Equations adjusting for potential confounders. Results:Of 4505 participants, 55% reported recent IPV during their trial participation. Women reported fearing violence (41%), emotional abuse (38%), being physically assaulted (16%), and forced sex (15%) by their regular male partner. IPV was associated with condom nonadherence in both study arms [adjusted odds ratio (AOR): 1.41, 95% confidence interval (CI): 1.24 to 1.61 (control arm) and AOR: 1.47, 95% CI: 1.28 to 1.69, (intervention arm)] and with diaphragm nonadherence (AOR 1.24, 95% CI: 1.06 to 1.45) adjusting for age, study sites, number of sex partners, and knowledge of male partner infidelity. Modeling effects of each form of IPV separately on nonadherence outcomes yielded similar results. Conclusions:Prevalence of recent IPV was high and associated with condom and diaphragm nonadherence during the trial. Counseling in prevention trials should proactively address IPV, for its own sake, and in product and risk-reduction counseling. Strategies to encourage mens positive involvement in product use and prevent IPV perpetration should be considered.

Degrees of disclosure: a study of women's covert use of the diaphragm in an HIV prevention trial in sub-Saharan Africa.

In sub-Saharan Africa more women are infected with HIV/AIDS than men and new prevention methods are urgently needed. One major attribute of female-initiated HIV prevention methods is that they can be used covertly, without a male partners knowledge. Using mixed methods, we explored the predictors and dimensions of covert use of the diaphragm in a randomized controlled trial that tested its effectiveness for HIV prevention. The Methods for Improving Reproductive Health in Africa (MIRA) trial was conducted in Zimbabwe and South Africa, and data collection took place between September 2003 and January 2007. This study is a secondary analysis of quantitative and qualitative data from participants randomized to the intervention group, and their male partners. It includes survey data from 2316 women (mean age=28.3), 14 focus group discussions (FGD) conducted with 104 women, and 7 FGD and 10 in-depth interviews with 37 male partners. The median follow-up for trial participation was 21 months (range: 12-24). At their final visit, approximately 9% of women had never disclosed to their primary partners that they were using the diaphragm (covert use). In multivariate analysis, predictors of covert use included being older, not co-habiting with the partner, having a partner who did not use condoms, and being from South Africa. Qualitative analysis revealed that covert use was not dichotomous, but ranged along a continuum, which we categorized into five levels (i.e. full disclosure; mostly open use; occasional covert use; mostly covert use; and completely covert use). We discuss the critical role of the option of covert use for many women in the context of an HIV prevention trial, as well as gender power dynamics which may influence womens decisions about disclosure.

User experiences and acceptability attributes of the diaphragm and lubricant gel in an HIV prevention trial in southern Africa

Abstract Methods for Improving Reproductive Health in Africa (MIRA), a phase III HIV prevention trial, was conducted among 5039 Zimbabwean and South African women to test the Ortho All-Flex diaphragm and Replens® lubricant gel. Among the 2418 intervention group participants, 105 women who had completed the trial and 41 male partners participated in focus group discussions and in-depth interviews about the acceptability of the diaphragm and gel and their experiences using the study products. Women who participated in the qualitative study had exited the trial in the prior nine months, were HIV negative, and used the diaphragm and gel for 12–24 months. The comprehensive and flexible conceptual framework was applied to investigate the salient attributes for acceptability of the products as potential HIV prevention methods, and emerging themes for acceptability were framed within three categories of attributes (product, relationship, and sexual intercourse attributes). Both diaphragm and gel were found to be highly acceptable in the study group, and the gel was popular due to its effect of enhancing sexual pleasure. Some of the important product attributes influencing acceptability as reported by users were convenience, ease of use, dual use potential for contraception and disease prevention, and being female-initiated. It was also noted that some elements (such as sexual pleasure, couple communication, and the necessity of diaphragm negotiation) could be more important than others in terms of influencing product acceptability and use. Acceptability attributes reflective of the broader contextual environment (beliefs generated in the trial community suggesting preventive efficacy – preventive method optimism – and gendered norms favoring male superiority in sexual decision making) also emerged as important themes. The high level of acceptability of the diaphragm and gel among MIRA trial participants and their male partners is an indicator of the continued need for an effective female-initiated product.

Finger Prick Dried Blood Spots for HIV Viral Load Measurement in Field Conditions in Zimbabwe

Background In the context of a community-randomized trial of antiretrovirals for HIV prevention and treatment among sex workers in Zimbabwe (the SAPPH-IRe trial), we will measure the proportion of women with HIV viral load (VL) above 1000 copies/mL (“VL>1000”) as our primary endpoint. We sought to characterize VL assay performance by comparing results from finger prick dried blood spots (DBS) collected in the field with plasma samples, to determine whether finger prick DBS is an acceptable sample for VL quantification in the setting. Methods We collected whole blood from a finger prick onto filter paper and plasma samples using venipuncture from women in two communities. VL quantification was run on samples in parallel using NucliSENS EasyQ HIV-1 v2.0. Our trial outcome is the proportion of women with VL>1000, consistent with WHO guidelines relating to regimen switching. We therefore focused on this cut-off level for assessing sensitivity and specificity. Results were log transformed and the mean difference and standard deviation calculated, and correlation between VL quantification across sample types was evaluated. Results A total of 149 HIV-positive women provided DBS and plasma samples; 56 (63%) reported being on antiretroviral therapy. VL ranged from undetectable-6.08 log10 using DBS and undetectable-6.40 log10 using plasma. The mean difference in VL (plasma-DBS) was 0.077 log10 (95%CI = 0.025–0.18 log10; standard deviation = 0.63 log10,). 78 (52%) DBS and 87 (58%) plasma samples had a VL>1000. Based on plasma ‘gold-standard’, DBS sensitivity for detection of VL>1000 was 87.4%, and specificity was 96.8%. Conclusion There was generally good agreement between DBS and plasma VL for detection of VL>1000. Overall, finger prick DBS appeared to be an acceptable sample for classifying VL as above or below 1000 copies/mL using the NucliSENS assay.

A QUALITATIVE STUDY OF OBSTACLES TO DIAPHRAGM AND CONDOM USE IN AN HIV PREVENTION TRIAL IN SUB-SAHARAN AFRICA

Consistent condom use and the substitution of condoms with potential HIV prevention methods of lower or unknown effectiveness are important concerns in the development of new prevention technologies. This qualitative study explored obstacles to consistent condom use with the diaphragm in MIRA, an HIV prevention trial in South Africa and Zimbabwe. We conducted 26 focus group discussions (FGDs) with 206 women and 7 FGDs and 10 in-depth interviews with 41 male partners of intervention-arm women. The belief that the diaphragm/gel prevented HIV, womens difficulties negotiating condom use, and mens unawareness that using the products together was recommended were obstacles to consistent condom use with the diaphragm/gel. Concerns about protection from HIV and pregnancy, recognition that the diaphragm was not yet proven to prevent HIV or sexually transmitted infections, and the trial context were facilitators. Understanding selective study product use in HIV prevention trials may inform improved adherence counseling and male involvement strategies.

Underage and underserved: reaching young women who sell sex in Zimbabwe

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.

Meeting family planning needs. PATH provides solutions to expand access to products and services.

This fact sheet describes PATHs work to expand access to family planning products and services in low-resource settings.The diaphragm is slowly but continuously losing ground against modern, industry-backed methods of contraception. It carries the odium of being oldfashioned, complicated to use, and unreliable. The diaphragm has a long history. Casanova (1725 – 1798) is often said to have used lemons for contraceptive purposes: after having been halved and squeezed, the rind was placed over the cervix as a diaphragm or a cervical cap. The citric acid (pH 2.4) released from the remaining pulp might have acted as a spermicide. The diaphragm, as we know it, is of much more recent origin. Made originally of rubber, later of latex, and now mostly of silicone, it is fi tted with a spring in its rim, that keeps the device in place. In 1882, the Dutch-born gynaecologist Wilhelm J. P. Mensinga (1836 – 1910), who was working in Germany, published (under the pseudonym of Dr Carl Hasse) the fi rst description of a rubber contraceptive device for vaginal use, consisting of a domeshaped membrane surrounded by a thicker ring. Later, a spring was molded into the rim. Diaphragms were introduced in the Netherlands in the following years by Aletta Jacobs (1854 – 1929) who distributed them to poor women in Amsterdam. So it has been with us nearly as long as the condom, which is not considered to be old-fashioned. The size of the diaphragm should be such that it fi ts the vagina comfortably. The woman is instructed how to insert it before coitus (Figure 1), so that it is correctly placed behind the symphysis and covers the cervix (Figure 2). It should be left in place after coitus for at least 6 – 8 hours, when the low pH of the vagina, in combination with the spermicidal gel or cream with which the diaphragm has been coated, will have incapacitated the sperm. Then the diaphragm is removed, washed and dried, and stowed away with corn fl our until the next sexual encounter. It is not more complicated to use than a tampon. Research about the effectiveness of the method is scant and only data from the USA are available1. According to Trussell the Pearl index for perfect use is 4.5 – 6 but the data upon which his calculation is based are rather limited 1 . It would be very useful to have more extensive data concerning women who have made a well-founded choice for a diaphragm and have been properly instructed. Among the patients whom I have seen the diaphragm appeared to be as reliable as the condom and it was usually preferred over the latter as a single method of contraception.

Changes in engagement in HIV prevention and care services among female sex workers during intensified community mobilization in 3 sites in Zimbabwe, 2011 to 2015

‘Sisters with a Voice’, Zimbabwes nationally scaled comprehensive programme for female sex workers (FSWs), intensified community mobilization activities in three sites to increase protective behaviours and utilization of clinical services. We compare indicators among FSWs at the beginning and after implementation.
