The Effect of Systemic Racism and Homophobia on Police Enforcement and Sexual and Emotional Violence among Sex Workers in East London: Findings from a Cohort Study.

There is extensive qualitative evidence of violence and enforcement impacting sex workers who are ethnically or racially minoritized, and gender or sexual minority sex workers, but there is little quantitative evidence. Baseline and follow-up data were collected among 288 sex workers of diverse genders (cis/transgender women and men and non-binary people) in London (2018-2019). Interviewer-administered and self-completed questionnaires included reports of rape, emotional violence, and (un)lawful police encounters. We used generalized estimating equation models (Stata vs 16.1) to measure associations between (i) ethnic/racial identity (Black, Asian, mixed or multiple vs White) and recent (6 months) or past police enforcement and (ii) ethnic/racial and sexual identity (lesbian, gay or bisexual (LGB) vs. heterosexual) with recent rape and emotional violence (there was insufficient data to examine the association with transgender/non-binary identities). Ethnically/racially minoritized sex workers (26.4%) reported more police encounters partly due to increased representation in street settings (51.4% vs 30.7% off-street, p = 0.002). After accounting for street setting, ethnically/racially minoritized sex workers had higher odds of recent arrest (adjusted odds ratio 2.8, 95% CI 1.3-5.8), past imprisonment (aOR 2.3, 95% CI 1.1-5.0), police extortion (aOR 3.3, 95% CI 1.4-7.8), and rape (aOR 3.6, 95% CI 1.1-11.5). LGB-identifying sex workers (55.4%) were more vulnerable to rape (aOR 2.4, 95% CI 1.1-5.2) and emotional violence. Sex workers identifying as ethnically/racially minoritized (aOR 2.1, 95% CI 1.0-4.5), LGB (aOR 2.0, 95% CI 1.0-4.0), or who use drugs (aOR 2.0, 95% CI 1.1-3.8) were more likely to have experienced emotional violence than white-identifying, heterosexual or those who did not use drugs. Experience of any recent police enforcement was associated with increased odds of rape (aOR 3.6, 95% CI 1.3-8.4) and emotional violence (aOR 4.9, 95% CI 1.8-13.0). Findings show how police enforcement disproportionately targets ethnically/racially minoritized sex workers and contributes to increased risk of rape and emotional violence, which is elevated among sexual and ethnically/racially minoritized workers.

How Can Programs Better Support Female Sex Workers to Avoid HIV Infection in Zimbabwe? A Prevention Cascade Analysis.

BACKGROUND: "HIV prevention cascades" have been proposed to support programs by identifying gaps in demand for, access to, and capability to adhere to HIV prevention tools, but there are few empirical examples to guide development. We apply a prevention cascade framework to examine prevention coverage and factors associated with condoms and/or PrEP adherence among female sex workers. SETTING: Seven sites across Zimbabwe. METHODS: Seven respondent-driven sampling surveys from the intervention sites of a pragmatic cluster-randomized trial in Zimbabwe in 2016 were analyzed, and 611/1439 women testing HIV-negative included. We operationalized key components of an HIV prevention cascade including demand, supply, and capability to adhere to 2 tools for HIV prevention: condoms and pre-exposure prophylaxis (PrEP). We used adjusted logistic regression to identify determinants of adherence to condoms and PrEP in turn, examining the effect of adherence to one tool on adherence to the other. RESULTS: There were 343/611, 54.7%, women reporting adherence to condoms and/or PrEP, leaving almost half uncovered. Although women were aware that condoms prevented HIV and reported good access to them, only 45·5% reported full adherence to condom use. For PrEP, a new technology, there were gaps along all 3 domains of demand, supply, and adherence. Alcohol use decreased adherence to PrEP and condoms. Younger and newer entrants to sex work were less likely to take PrEP every day. CONCLUSIONS: HIV prevention programming among female sex workers in Zimbabwe could consider increasing awareness of PrEP alongside supply, alcohol use interventions, and approaches to engaging younger women.

Changes Over Time in HIV Prevalence and Sexual Behaviour Among Young Female Sex-Workers in 14 Sites in Zimbabwe, 2013-2016.

Young female sex-workers (FSW) aged 18-24 are at high risk of HIV due to high numbers of sexual partners, difficulty negotiating condom use, increased risk of gender-based violence, and limited access to services. Here we describe changes in sexual behaviours among young FSW across Zimbabwe between 2013 and 2016, and risk factors for prevalent HIV in 2013 and 2016. FSW ≥ 18 years were recruited using respondent-driven sampling in 14 sites across Zimbabwe in 2013 and 2016 as part of the SAPPH-IRe trial. We collected data on socio-demographics and sexual behaviour and offered HIV testing. Statistical analyses were RDS-II weighted. Characteristics of young FSW aged 18-24 were described, stratified by age. Logistic regression was used to assess difference in sexual behaviours by reported HIV status between 2013 and 2016, and to explore associations with prevalent HIV in 2013 and 2016. 656 young FSW were recruited in 2013 and 503 in 2016. Characteristics of young FSW were similar across both surveys. HIV prevalence was similar at both time points (35% vs 36%) and rose steeply with age. Compared to young FSW in 2013, reported condom-less sex with a steady partner and condom-less sex with clients was higher in 2016 among women self-reporting HIV negative status (OR = 6.41; 95%CI: 3.40-12.09; P<0.001) and (OR = 1.69; 95%CI: 1.14-2.51, P = 0.008), respectively, but not among young FSW self-reporting HIV positive status (OR = 2.35; 95%CI: 0.57-9.76; P = 0.236) and (OR = 1.87; 95%CI: 0.74-4.74; P = 0.186). After adjusting for age in 2016, young FSW who had ever been married had increased odds of testing HIV positive (OR = 1.88; 95% CI 1.04-3.39; P = 0.036) compared with those who had never married. Young FSW who completed secondary education or higher were less likely to test HIV positive (OR = 0.41; 95% CI 0.20-0.83; P = 0.012) compared with those with primary education or less. Young FSW remain at very high risk of HIV. Strategies to identify young FSW when they first start selling and refer them into services that address their economic, social and sexual vulnerabilities are critical.

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.

INTRODUCTION: 'Sisters with a Voice', Zimbabwe's 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. METHODS: We used mixed methods to collect data at three sites: in-depth interviews (n = 22) in 2015, routine clinical data from 2010 to 2015, and two respondent driven sampling surveys in 2011 and 2015, in which participants completed an interviewer-administered questionnaire and provided a finger prick blood sample for HIV antibody testing. Estimates were weighted using RDS-1 and estimate convergence assessed in both years. We assessed differences in six indicators between 2011 and 2015 using logistic regression adjusted for age, duration in sex work and education. RESULTS: 870 FSWs were recruited from the three sites in 2011 and 915 in 2015. Using logistic regression to adjust for socio-demographic differences, we found higher estimates of the proportion of HIV-positive FSWs and HIV-positive FSWs who knew their status and reported being on ART in Mutare and Victoria Falls in 2015 compared to 2011. Reported condom use with clients did not differ by year; however, condom use with regular partners was higher in 2015 in Mutare and Hwange. Reported HIV testing in the last six months among HIV-negative FSWs was higher in 2015 across sites: for instance, in Victoria Falls it was 13.4% (95% CI 8.7% to 19.9%) in 2011 and 80.8% (95% CI 74.0 to 87.7) in 2015. FSWs described positive perceptions of the Sisters programme, ease of engaging with health services, and improved solidarity among peers. Programme data showed increases in service use by 2015 across all sites. CONCLUSIONS: Improvements in key HIV care engagement indicators were observed among FSWs in two sites and in testing and prevention indicators across the three sites after implementation of an intensified community mobilization intervention. Engagement with services for FSWs is critical for countries to reach 90-90-90 targets.

Engagement in HIV Care Among Young Female Sex Workers in Zimbabwe.

INTRODUCTION: Young female sex workers (FSWs) are at greater HIV risk than their older counterparts. Yet, the extent of their engagement with HIV services is largely unknown. We compared engagement among FSWs aged 18-24 years with those 25 years and older. METHODS: We used respondent-driven sampling to recruit FSWs from 14 communities in Zimbabwe from November to December 2013. We collected data on demographics, behavior, service uptake, and HIV and viral load testing. Data were pooled and weighted using respondent-driven sampling-2 estimation. We analyzed HIV care cascade variables by age group. To identify potential drivers of younger FSW service use, we explored factors associated with knowing one's HIV status. RESULTS: Among 2617 participants, mean age was 31 years and 26% were 18-24 years. Over half of FSWs initiated sex work before the age of 25 years. Overall HIV prevalence was 59% but was lower among younger FSWs (35% vs 67%, P < 0.01). Younger HIV-infected FSWs were significantly less engaged at each step of the care cascade. Among younger FSWs reporting antiretroviral therapy use, 62% had an undetectable viral load compared with 79% in older FSWs. In multivariable regression, young FSWs encouraged to have an HIV test by another FSW (adjusted odds ratio = 2.54; 95% confidence interval: 1.44 to 4.50), and those with no recent clients (adjusted odds ratio = 4.31; 95% confidence interval: 1.30 to 14.33) were more likely to report knowing their status. CONCLUSIONS: The high proportion of FSWs initiating sex work before the age of 25 years and their lower engagement in HIV services highlights the importance of considering this vulnerable population in HIV programming. Implementing targeted services tailored to the unique needs of young FSWs is a public health imperative.

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

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.

Implementation and Operational Research: Cohort Analysis of Program Data to Estimate HIV Incidence and Uptake of HIV-Related Services Among Female Sex Workers in Zimbabwe, 2009-2014.

BACKGROUND: HIV epidemiology and intervention uptake among female sex workers (FSW) in sub-Saharan Africa remain poorly understood. Data from outreach programs are a neglected resource. METHODS: Analysis of data from FSW consultations with Zimbabwe's National Sex Work program, 2009-2014. At each visit, data were collected on sociodemographic characteristics, HIV testing history, HIV tests conducted by the program and antiretroviral (ARV) history. Characteristics at first visit and longitudinal data on program engagement, repeat HIV testing, and HIV seroconversion were analyzed using a cohort approach. RESULTS: Data were available for 13,360 women, 31,389 visits, 14,579 reported HIV tests, 2750 tests undertaken by the program, and 2387 reported ARV treatment initiations. At first visit, 72% of FSW had tested for HIV; 50% of these reported being HIV positive. Among HIV-positive women, 41% reported being on ARV. 56% of FSW attended the program only once. FSW who had not previously had an HIV-positive test had been tested within the last 6 months 27% of the time during follow-up. After testing HIV positive, women started on ARV at a rate of 23/100 person years of follow-up. Among those with 2 or more HIV tests, the HIV seroconversion rate was 9.8/100 person years of follow-up (95% confidence interval: 7.1 to 15.9). CONCLUSIONS: Individual-level outreach program data can be used to estimate HIV incidence and intervention uptake among FSW in Zimbabwe. Current data suggest very high HIV prevalence and incidence among this group and help identify areas for program improvement. Further methodological validation is required.

Competition is not necessarily a barrier to community mobilisation among sex workers: an intervention planning assessment from Zimbabwe.

BACKGROUND: Community mobilization among female sex workers (SWs) is recognized as an effective strategy to empower SWs and increase their uptake of health services. Activities focus on increasing social cohesion between SWs by building trust, strengthening networks, and encouraging shared efforts for mutual gain. Several studies, however, suggest that high levels of interpersonal competition between SWs can pose a barrier to collective action and support. We conducted a study to examine levels of perceived competition between SWs in Mutare, Hwange and Victoria Falls in Zimbabwe in order to inform development of a community-based intervention for HIV prevention and treatment. This paper focuses on our qualitative findings and their implications for the design of HIV programming in the Zimbabwean context. METHODS: Following a respondent driven sampling (RDS) survey, we explored issues related to social cohesion amongst SWs in Mutare, Hwange and Victoria Falls through in-depth interviews conducted with 22 SWs. Interviews examined dynamics of SWs' relationships and extent of social support, and were analyzed using thematic content analysis using the constant comparative method. Findings are contextualised against descriptive data extracted from the survey, which was analysed using Stata 12, adjusting for RDS. RESULTS: Across all sites, women described protecting each other at night, advising each other about violent or non-paying clients, and paying fines for each other following arrest. In Mutare, women gave additional examples, including physically attacking problem clients, treatment adherence support and shared saving schemes. However, interviews also highlighted fierce competition between women and deep mistrust. This reflects the reported mix of competition and support from the survey of 836 women (Mutare n = 370, Hwange n = 237, Victoria Falls n = 229). In Mutare, 92.8 % of SWs agreed there was a lot of competition; 87.9 % reported that SWs support each other. This contrasted with Victoria Falls and Hwange where fewer agreed there was competition between SWs (70.5 % and 78.0 %), but also fewer reported that SWs support each other at work (55.2 % and 51.2 %). CONCLUSIONS: Women reported being most likely to support each other when confronted with serious danger but maintained high levels of competition for clients, suggesting competition at work does not represent a barrier to support. Examples of practical assistance between SWs provide entry points for our planned community mobilization activities, which aim to broaden trust and support among SWs while acknowledging their professional competition.

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.

Triple jeopardy: adolescent experiences of sex work and migration in Zimbabwe.

Adolescence, migration and sex work are independent risk factors for HIV and other poor health outcomes. They are usually targeted separately with little consideration on how their intersection can enhance vulnerability. We interviewed ten women in Zimbabwe who experienced sex work and migration during adolescence, exploring implications for their health and for services to meet their needs. For most, mobility was routine throughout childhood due to family instability and political upheaval. The determinants of mobility, e.g. inability to pay school fees or desire for independence from difficult circumstances, also catalysed entry into sex work, which then led to further migration to maximise income. Respondents described their adolescence as a time of both vulnerability and opportunity, during which they developed survival skills. While these women did not fit neatly into separate risk profiles of "sex worker" "migrant" or "adolescent", the overlap of these experiences shaped their health and access to services. To address the needs of marginalised populations we must understand the intersection of multiple risks, avoiding simplified assumptions about each category.

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

OBJECTIVES: 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 men's positive involvement in product use and prevent IPV perpetration should be considered.

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

BACKGROUND: Although 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. METHODS: Three 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. RESULTS: SWs 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. CONCLUSION: Improving 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.

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, women's difficulties negotiating condom use, and men's 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.

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

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.

Feasibility and potential acceptability of three cervical barriers among vulnerable young women in Zimbabwe.

BACKGROUND: We explored the potential acceptability of three cervical barriers (CB) (Ortho All-Flex diaphragm, SILCS diaphragm, FemCap cervical cap) among sexually experienced Zimbabwean young women. METHODS: Forty-five young women (aged 16-21 years) received an individual CB educational session. Participants were then randomly assigned to one of the three CBs in a 1:1:1 ratio, and practised insertion and removal of their device at the clinic. Next, participants were interviewed on their practice experiences, and their post-practice attitudes towards CB. RESULTS: All 45 young women were willing and able to insert their assigned device. The majority reported "easy" insertion and removal and 93% "liked" the device they tried. All showed interest in participating in future CB studies: when asked which device they would like to try in the future, over half (58%) chose SILCS, regardless of the device they had tried. The majority felt comfortable touching their genitals to insert/remove the CB and most participants favoured methods' attributes associated with female-control and non-interference with sex. Over half the participants said they would prefer to use a CB continuously compared to episodic use. Two-thirds of them expressed interest in CB for dual protection. CONCLUSION: The concept of CB, and initial insertion experience, were well accepted in this selected, small group of Zimbabwean young women. Evaluating CB in larger studies seems feasible in this population.

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 partner's 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 women's decisions about disclosure.
