How Can We Support the Use of Oral PrEP Among Young Women who Sell Sex? A PrEP Cascade Analysis.
Ontology highlight
ABSTRACT: Background
We constructed self-reported pre-exposure prophylaxis (PrEP) cascades and explored factors associated with and barriers to PrEP use to inform efforts to support PrEP use among young women who sell sex.Methods
Using self-reported data from HIV-negative young women who sell sex enrolled into a cohort study using respondent-driven sampling in Zimbabwe, we constructed PrEP cascades assessing knowledge of, ever offered, ever used, and current PrEP use in 2017 and 2019. We used logistic regression to examine factors associated with PrEP use by 2019. Through qualitative interviews with 43 women enrolled in the cohort, we investigated barriers to PrEP use.Results
At enrollment, 50% of women had heard of PrEP, 12% had ever been offered PrEP, and 7% ever used PrEP. Over time, all cascade domains: 96% of women had heard of and 55% reported an active offer of PrEP. Among women retained in the study in 2019 (56%; n = 538), 34% ever took PrEP by 2019. PrEP use was associated with, at enrollment, reporting more clients in the past month (10+: 45% vs 1-3: 27% adjOR = 1.71 95% CI: 1.06 to 2.76), duration of selling sex (24% <2 years vs 38% 2-3 years; adjOR = 0.51 95% CI: 0.32 to 0.83), and having visited a female sex worker program in the past 12 months (55% vs 27%; adjOR = 2.92 95% CI: 1.91 to 4.46). Qualitative interviews revealed fear of disclosing sex work, HIV-related/ART-related stigma, and (opportunity) costs of accessing PrEP as barriers to use.Conclusion
PrEP use was associated with factors known to increase HIV risk. Fear of stigma, disclosure, and supply-side barriers need to be addressed to increase women's ability to use PrEP.

Project description:HIV prevalence among cisgender female sex workers (FSW) and/or women who use drugs (WWUD) is substantially higher compared to similarly aged women. Consistent with PRISMA guidelines, we conducted the first systematic review on the pre-exposure prophylaxis (PrEP) continuum among FSW and/or WWUD, searching PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included: reporting a PrEP related result among FSW and/or WWUD aged 18 + ; peer-reviewed; and published in English between 2012 and 2018. Our search identified 1365 studies; 26 met eligibility requirements, across the following groups: FSW (n = 14), WWUD (n = 9) and FSW-WWUD (n = 3). Studies report on at least one PrEP outcome: awareness (n = 12), acceptability (n = 16), uptake (n = 4), and adherence (n = 8). Specific barriers span individual and structural levels and include challenges to daily adherence, cost, and stigma. Combining health services and long-acting PrEP formulas may facilitate better PrEP uptake and adherence. The limited number of studies indicates a need for more research.

Project description:Images of scantily clad women are used by advertisers to make products more attractive to men. This "sex sells" approach is increasingly employed to promote ethical causes, most prominently by the animal-rights organization PETA. Yet sexualized images can dehumanize women, leaving an unresolved paradox--is it effective to advertise an ethical cause using unethical means? In Study 1, a sample of Australian male undergraduates (N = 82) viewed PETA advertisements containing either sexualized or non-sexualized images of women. Intentions to support the ethical organization were reduced for those exposed to the sexualized advertising, and this was explained by their dehumanization of the sexualized women, and not by increased arousal. Study 2 used a mixed-gender community sample from the United States (N = 280), replicating this finding and extending it by showing that behaviors helpful to the ethical cause diminished after viewing the sexualized advertisements, which was again mediated by the dehumanization of the women depicted. Alternative explanations relating to the reduced credibility of the sexualized women and their objectification were not supported. When promoting ethical causes, organizations may benefit from using advertising strategies that do not dehumanize women.

Project description:IntroductionYoung female sex workers (FSW) are disproportionately vulnerable to HIV. Zimbabwe data show higher HIV incidence and lower engagement in services compared to older FSW. Utilizing data from a combination HIV prevention and treatment intervention, we describe engagement in the HIV services over time among FSW 18-24 years, compared to those ≥25 years of age.Materials and methodsData were collected via respondent-driven sampling (RDS) surveys in 14 communities in 2013 and 2016, with >2500 FSW per survey. They included blood samples for HIV and viral load testing. As the intervention had no significant impact on HIV care cascade outcomes, data were aggregated across study arms. Analyses used RDS-II estimation.ResultsMean age in 2013 and 2016 was 31 and 33 years, with 27% and 17% aged 18-24 years. Overall HIV prevalence was 59% at each timepoint, and 35% and 36% among younger FSW. From 2013 to 2016 there was an increase in young HIV-positive FSW knowing their status (38% vs 60%, OR = 2.51, p<0.01). Outcomes for all FSW improved significantly over time at all steps of the cascade, and the relative change over time was similar among older versus younger FSW for most cascade variables.DiscussionYoung FSW had improvements in care cascade outcomes, and proportionate improvements similar to older FSW, yet they remain less engaged in services overall. This implies that the dedicated FSW services in Zimbabwe are having a comparably positive impact across age groups, however more is likely required to address young FSW's unique vulnerabilities and needs.

Project description:IntroductionThere is limited understanding of how social dynamics impact pre-exposure prophylaxis (PrEP) adherence among adolescent girls and young women (AGYW) in generalized HIV-epidemic settings. We examined experiences of oral PrEP use disclosure to various social groups with the goal of identifying supportive relationships that can be leveraged to promote adherence.MethodsWe used qualitative methods to explore experiences disclosing PrEP use and the perceived impact of disclosure on adherence among 22 South African AGYW (16-25 years) taking daily oral PrEP. Serial in-depth-interviews (IDIs) were conducted 1-, 3-, and 12-months post-PrEP initiation. Respondents also self-reported their disclosures separately for various social groups and adherence was assessed using intracellular tenofovir-diphosphate levels.ResultsQualitative respondents had a median age of 20.5 years and reported disclosing their PrEP use to friends (n = 36 total disclosures), partners, siblings, other family members (n = 24 disclosures each), and parents (n = 19 disclosures). IDI data revealed that parents and partners provided the most support to respondents and a lack of support from these groups was most often perceived as negatively affecting PrEP use. AGYW described difficulties explaining PrEP to their mothers, who believed PrEP was HIV treatment or would lead to HIV infection. Disclosure to household members was notably meaningful for AGYW (both positively and negatively). Respondents reported leveraging supportive relationships for pill reminders. For respondents who perceived a household member would be unsupportive, however, non-disclosure was less feasible and PrEP use was often stigmatized. To avoid stigma, several respondents hid or discontinued PrEP.ConclusionsWhile supportive relationships may facilitate PrEP use, disclosure can also lead to stigma. Counselors should support AGYW in disclosing to key people in their social networks and provide AGYW with materials that lend credibility to explanations of PrEP. Community education is necessary to alleviate PrEP-related stigma and facilitate disclosure.

Project description:IntroductionHIV incidence remains high among African adolescent girls and young women (AGYW), who would benefit from pre-exposure prophylaxis (PrEP). Strategies to increase PrEP adherence and persistence need to be evaluated in African AGY, including incentives conditional on high adherence.MethodsThe 3Ps for Prevention Study was a 12-month prospective cohort of 200 women ages 16 to 25 initiating PrEP in South Africa from 2017 to 2018. Participants received retrospective feedback about drug levels at Months 1, 2 and 3; half was randomized to receive a 200 Rand shopping voucher ($13 US) at Months 2, 3 and 4, conditioned on high intracellular tenofovir diphosphate (TFV-DP) levels in dried blood spots (≥500 fmol/punch at Month 1, ≥700 fmol/punch at Months 2 and 3). The primary analysis was intention-to-treat, comparing the proportion with high PrEP adherence (≥700 fmol/punch) at Month 3 by randomized group, based on 100% efficacy among men who have sex with men.ResultsMedian age of the 200 women was 19 years (interquartile range [IQR] 17, 21); 86% had a primary sexual partner. At Month 3, the mean TFV-DP level was 822 fmol/punch (SD 522) in the incentive group and 689 fmol/punch (SD 546) in the control group (p = 0.11). Forty-five (56%) of 85 women in the incentive group and 35 (41%) of 85 women in the control group had TFV-DP levels ≥700 fmol/punch (RR 1.35; 95% CI 0.98, 1.86; p = 0.067), which declined to 8% and 5% in the incentive and control groups at Month 12 (no significant difference by arm). 44% refilled PrEP without gaps, 14% had a gap of ≥3 weeks in coverage subsequently restarted PrEP and 54% accepted at the final dispensing visit at Month 9. No new HIV infections were observed after PrEP initiation.ConclusionsAmong South African AGYW initiating PrEP, drug levels indicated high PrEP adherence in almost half of women at Month 3, with a non-statistically significant higher proportion with high adherence among those in the incentive group. Over half persisted with the 12-month PrEP programme although high adherence declined after Month 3. Strategies to support PrEP adherence and persistence and longer-acting PrEP formulations are needed.

Project description:BACKGROUND:Across Sub-Saharan Africa, young women who sell sex (YSW) face institutional barriers in accessing sexual health and HIV prevention programs designed for female sex workers. In 2018, Kenya developed a national framework to guide service provision for YSW aged 14-24?years. To help inform the implementation of the framework, we estimated the burden of vulnerabilities related to the Sustainable Development Goals (SDGs related to health and gender equality) and program contact among YSW. METHODS:We used data from Transitions, a 2015 bio-behavioural cross-sectional survey of 408 YSW aged 14-24?years in Mombasa, Kenya. We estimated the prevalence of sexual (inconsistent condom use), structural (financial, violence), and reproductive health vulnerabilities; and characterized engagement with local HIV programs tailored to sex workers. We then compared the prevalence of vulnerabilities by age group (14-18?years, N?=?117; 19-24?years, N?=?291) and by program contact (ever contacted by local program for sex workers). RESULTS:47.3% reported inconsistent condom use with any partner in the previous week (no difference by age-group, p?=?1.00). Structural vulnerabilities were common and did not vary by age: 83.6% did not have a regular source of income; 29.9 and 29.2% had experienced physical and sexual violence, respectively. 26.5% reported at least one pregnancy before age 18, and 18.5% used a non-reliable form of contraception with little variability by age. 25.7% were aware of at least one program, and only 13.7% of YSW had ever been contacted by a program (8.5% of those aged 14-18?years; and 15.8% of those aged 19-24?years, p?=?0.06). Sexual, structural, and reproductive health vulnerabilities did not vary by program contact. CONCLUSIONS:SDG-related vulnerabilities begin early in the lives of YSW who are not currently reached by programs designed for female sex workers.

Project description:Although Kenya nationally scaled up oral pre-exposure prophylaxis (PrEP) in May 2017, adolescent girls' (AG, aged 15-19 years) and young women's (YW, aged 20-24 years) PrEP use remains suboptimal. Thus, we analyzed PrEP consultations-interactions with a healthcare provider about PrEP-among Kenyan AGYW. In April-June 2018, AGYW enrolled in DREAMS in Kisumu County, Kenya self-reported their HIV-related knowledge, behaviors, and service use. Among HIV negative, sexually active AG (n = 154) and YW (n = 289), we examined associations between PrEP eligibility and PrEP consultations using prevalence ratios (PR, adjusted: aPR). Most AG (90.26%) and YW (94.12%) were PrEP-eligible due to inconsistent/no condom use, violence survivorship, or recent sexually transmitted infection symptoms. Between PrEP-eligible AG and YW, more YW were ever-orphaned (58.09%), ever-married (54.41%), ever-pregnant (80.88%), and out of school (78.31%); more PrEP-eligible YW reported PrEP consultations (41.18% vs. 24.46%, aPR = 1.51 [1.01-2.27]). AG who used PEP (post-exposure prophylaxis) reported more consultations (aPR = 5.63 [3.53-8.97]). Among YW, transactional sex engagers reported more consultations (58.62% vs. 39.09%, PR = 1.50 [1.06-2.12]), but only PEP use (aPR = 2.81 [2.30-3.43]) and multiple partnerships (aPR = 1.39 [1.06-1.82]) were independently associated with consultations. Consultations were lowest among those with 1 eligibility criterion (AG = 11.11%/YW = 27.18%). Comparatively, consultations were higher among AG and YW with 2 (aPR = 3.71 [1.64-8.39], PR = 1.60 [1.07-2.38], respectively) or ≥ 3 (aPR = 2.51 [1.09-5.78], PR = 2.05 [1.42-2.97], respectively) eligibility criteria. Though most AGYW were PrEP-eligible, PrEP consultations were rare and differed by age and vulnerability. In high-incidence settings, PrEP consultations should be conducted with all AGYW. PrEP provision guidelines must be re-assessed to accelerate AGYW's PrEP access.

Project description:BackgroundOral contraceptive use has been previously associated with an increased risk of suicidal behavior in some, but not all, samples. The use of large, representative, longitudinally-assessed samples may clarify the nature of this potential association.MethodsWe used Swedish national registries to identify women born between 1991 and 1995 (N = 216 702) and determine whether they retrieved prescriptions for oral contraceptives. We used Cox proportional hazards models to test the association between contraceptive use and first observed suicidal event (suicide attempt or death) from age 15 until the end of follow-up in 2014 (maximum age 22.4). We adjusted for covariates, including mental illness and parental history of suicide.ResultsIn a crude model, use of combination or progestin-only oral contraceptives was positively associated with suicidal behavior, with hazard ratios (HRs) of 1.73-2.78 after 1 month of use, and 1.25-1.82 after 1 year of use. Accounting for sociodemographic, parental, and psychiatric variables attenuated these associations, and risks declined with increasing duration of use: adjusted HRs ranged from 1.56 to 2.13 1 month beyond the initiation of use, and from 1.19 to 1.48 1 year after initiation of use. HRs were higher among women who ceased use during the observation period.ConclusionsYoung women using oral contraceptives may be at increased risk of suicidal behavior, but risk declines with increased duration of use. Analysis of former users suggests that women susceptible to depression/anxiety are more likely to cease hormonal contraceptive use. Additional studies are necessary to determine whether the observed association is attributable to a causal mechanism.

Project description:AimsWe aim to estimate the number of HIV pre-exposure prophylaxis (PrEP) users among men having sex with men (MSM) in Germany from 2017 through 2020, and analyse if PrEP needs expressed in 2017 might have been met by the expansion of PrEP until 2020.Subject and methodsWe estimated the number of PrEP users by using drug prescription data and information on on-demand/intermittent PrEP use from online surveys to determine the proportion of on-demand/intermittent and daily PrEP use as well as the average number of PrEP pills used.The number of MSM in need of PrEP in 2017 was estimated based on four groups defined among respondents to a large online survey, combining respondents with PrEP use intention and respondents indicating substantial sexual risks. The size of each group was estimated based on self-selection biases. MSM with PrEP need in 2017 were compared with the estimated number of persons taking PrEP by June 2020.ResultsWe estimated a total of 15,600 to 21,600 PrEP users in Germany by the end of June 2020, corresponding to 40-55% of men with PrEP use intention in 2017. A correlation between the regional distribution of PrEP use intention in 11/2017 and actual PrEP use by 06/2020 suggested an unequal regional distribution of unsatisfied needs. The number of men with unmet PrEP needs ranged between 27,500 and 93,000 in 06/2020.ConclusionPrEP use in Germany has increased considerably between 10/2017 and 06/2020, but large regional inequalities persist. PrEP is not yet readily accessible, and there is a need to expand services and encourage uptake.Supplementary informationThe online version contains supplementary material available at 10.1007/s10389-022-01699-y.

Project description:Daily oral pre-exposure prophylaxis (PrEP) is a key tool in addressing high HIV incidence among young women, and breaking the cycle of transmission. From 2017 to 2020, Médecins Sans Frontières (MSF) offered PrEP, in conjunction with contraception and risk-reduction counselling, to women aged 18-25, in a government-run clinic in Khayelitsha, a low income high HIV prevalence area in South Africa. Drawing on clinical, quantitative, and qualitative interview data, we describe participants' experiences and engagement with the PrEP program, participant adherence (measured by TFV-DP levels in dried blood spots) over time, and the indirect benefits of the PrEP program. Of 224 screened and eligible participants, 164 (73.2%) initiated PrEP, with no large differences between those who initiated and those who did not. Overall, 47 (29%) completed 18 months follow-up, with 15 (9.1%) attending all visits. 76 (46.9%) participants were lost to follow-up, 15 (9.1%) exited when leaving the area, and 28.7% of exits happened in the first month of the study. We identified two different trajectories of PrEP adherence: 67% of participants had, on average, consistently low TFV-DP levels, with the remaining 33% having sustained high adherence. Few baseline characteristics predicted good adherence. The main reported barrier to taking PrEP was forgetting to take or travel with the pills. Encouragement from others declined as a reported facilitator from month 6 to 18 (family: 93.1% vs 77.6%, p = 0.016, friends: 77.6% vs 41.4%, p ≤ 0.001, partners: 62.1% vs 46.6%, p = 0.096, other PrEP users: 89.7% vs 74.1%, p = 0.020). Disclosure to friends and family in some cases opened dialogue around sex, and helped to educate others about PrEP. Self-reported sex with more than one partner, and sex without a condom, decreased significantly after enrolment (p < 0.001, p = 0.063). In the individual interviews, participants credited their PrEP experience with changing their behaviour. Recognising the challenges with, but overall benefits from a package of care that includes the option of PrEP, lessons drawn from this study can help maximise persistence on PrEP within resource constraints. PrEP providers need to address participants' need for both convenience and social support.
