Abstract
INTRODUCTION Adolescent girls and young women (AGYW), a priority population for HIV prevention in Africa, show high interest but difficulty in sustained effective use of pre-exposure prophylaxis (PrEP). With ongoing PrEP scale-up focused on increasing access, it is important to understand what influences AGYW's choice of PrEP delivery platforms. METHODS The POWER implementation study in Cape Town provided PrEP between 2017 and 2020 to AGYW (16-25 years) from four differentiated delivery platforms: mobile clinic, government facility, courier delivery or community-based youth club. Healthcare providers at government and mobile clinics provided PrEP (initiation and refills) as part of comprehensive, integrated sexual and reproductive health services. Courier and youth club platforms provided light-touch PrEP refill services incorporating rapid HIV self-testing. We conducted in-depth interviews with a purposive sample of AGYW who had ≥3 months of PrEP-use and accessed ≥2 PrEP delivery platforms. The thematic analysis explored AGYW's preferences, decision-making and habits related to PrEP access to inform market segmentation. RESULTS We interviewed 26 AGYW (median age 20) PrEP-users between November 2020 and March 2021. AGYW PrEP-users reported accessing different services with, 24 accessing mobile clinics, 17 courier delivery, 9 government health facilities and 6 youth clubs for their PrEP refills. Qualitative findings highlighted four potential behavioural profiles. The "Social PrEP-user" preferred PrEP delivery in peer spaces, such as youth clubs or adolescent-friendly mobile clinics, seeking affirmation and social support for continued PrEP use. The "Convenient PrEP-user" favoured PrEP delivery at easily accessible locations, providing quick (courier) or integrated contraception-PrEP refill visits (mobile and government clinic). The "Independent PrEP-user" preferred PrEP delivery that offered control over delivery times that fit into their schedule, such as the courier service. The "Discreet PrEP-user" highly valued privacy regarding their PrEP use (courier delivery) and avoided delivery options where unintentional disclosure was evident (youth club). Comfort with HIV self-testing had minimal influence on PrEP delivery choice. CONCLUSIONS Market segmentation of AGYW characterizes different types of PrEP-users and has the potential to enhance tailored messaging and campaigns to reach specific segments, with the aim of improving sustained PrEP use and HIV prevention benefits.

Abstract
INTRODUCTION Adolescent girls and young women (AGYW) face barriers that jeopardize their prevention-effective use of daily oral pre-exposure prophylaxis (PrEP). We sought to understand factors that influence AGYW's prolonged breaks in PrEP use, and their decisions to re-initiate or discontinue using PrEP in the context of a community-based adherence support intervention. METHODS In-depth interviews (IDIs) were conducted between December 2019 and April 2021 with purposively selected AGYW (aged 16-25) enrolled in the Community PrEP Study (CPS) in Buffalo City Metro Health District, Eastern Cape Province, South Africa. AGYW were offered monthly PrEP for 24 months at two community-based study sites. Interview guides were informed by the Information-Motivation-Behavioural Skills Model, and data were analysed using illustrative code reports and a case analysis. RESULTS A total of 603 participants were enrolled and initiated on PrEP in the parent study. Fifty-three IDIs were conducted with 50 CPS participants. Findings revealed that external factors (e.g. local movement, school holidays and medication side-effects) and social conflicts (e.g. discretion and partner mistrust) directly influenced breaks in PrEP usage. A decrease in one's self-perception of HIV risk prolonged the duration of these "PrEP breaks." Once PrEP refill visits were missed, some AGYW delayed returning for refills out of fear of being scolded by study staff. The differences between those participants who eventually re-initiated PrEP and those who disengaged from PrEP use can be attributed to social support and encouragement, level of familiarity with PrEP, risk perceptions, self-initiated discussions with staff and diminishing side effects. CONCLUSIONS Despite implementing a community-based PrEP delivery platform and behavioural intervention that included support for daily oral PrEP adherence and disclosure, participants struggled with consistent daily oral PrEP use. Unpredictable life events, including local movement and schooling schedules, in addition to being judged for their perceived behaviours, pose a challenge for consistent pill pick-up for AGYW and habit formation. Long-acting injectable PrEP may mitigate a number of these external barriers. Interventions that integrate long-term planning skills, how to navigate existing social judgements and how to access sources of social support may further improve habit formation for PrEP use, regardless of its formulation.

Abstract
INTRODUCTION HIV pre-exposure prophylaxis (PrEP) significantly reduces the risk of HIV acquisition. However, studies have demonstrated discordance between self-reported measures and biomedical benchmarks of PrEP adherence. We estimated the correlation between self-reported PrEP adherence and PrEP biomarkers and explored factors associated with adherence among men who have sex with men (MSM) in Nigeria. METHODS TRUST-PrEP, an open-label, prospective study; conducted in Abuja between April 2018 and May 2019. MSM ≥ 18 years with substantial HIV risk were enrolled. Participants reported PrEP adherence in the last month using a 4-point scale from "poor" to "perfect" and serum samples for PrEP biomarkers were collected at months 3 and 9. Serum tenofovir concentration was measured by liquid chromatography-tandem mass spectrometry and considered protective for adherence if ≥ 4.2 ng/ml. Spearman's rank correlation was used to estimate correlation between self-reported adherence and measured tenofovir levels. Generalized estimating equations with a logit link was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for associations between self-reported adherence and laboratory-measured adherence. RESULTS A total of 219 MSM with median age 23 (interquartile range 20-27) years had at least one PrEP biomarker assay. Only 66/219 (30%) had at least one record of protective tenofovir concentration. Correlation between tenofovir and self-reported adherence at 3 and 9 months were 0.1 and 0.02 respectively. Furthermore, 17/219 (8%,) and 49/219 (22%) had serum tenofovir of 4.2-35.4 ng/mL and ≥ 35.5 ng/mL, corresponding to at least 4 and 7 days' PrEP use in a week, respectively. PrEP adherence was higher among participants introduced to PrEP in the clinics compared with communities (aOR: 8.35, 95%CI: [3.24, 21.5]) and those with same-sex practices family disclosure (aOR: 3.60 95% CI: [1.73, 7.51]). CONCLUSION Self-reported PrEP adherence poorly correlated with biomarkers. Facilitating clinic-based PrEP introduction and disclosure of same-sex practices to family among MSM may improve PrEP adherence.

Abstract
This meta-analysis synthesized the proportion of adolescents and young adults (AYAs) who are adherent to pre-exposure prophylaxis (PrEP) and factors moderating adherence. A systematic search was conducted of studies published through May 2020 using PubMed, PsycInfo, Cochrane, EMBASE, and CINAHL. Included studies reported the proportion of AYAs (mean age ≤ 29 years) who were PrEP adherent. PrEP adherence was meta-analyzed using random-effects models. Secondary analyses evaluated potential moderating variables. A total of 41 individual samples, from 29 studies, of 8,679 AYA (weighted average age = 23.8 years) were synthesized. The proportion of AYA who met study-defined thresholds for PrEP adherence was .64 (95% confidence interval .57-.71) across studies. Subgroup analyses revealed that adherence was lower in young cisgender women (.46) than young men who have sex with men (.65) and serodiscordant heterosexual couples (.98). Adherence was higher in studies initiated after 2012 (.70) than earlier studies (.47). No differences based on participant age, country, or strategies to promote adherence were found. Across published studies to date, 64% of AYA demonstrate adequate PrEP adherence. Findings can be used to guide PrEP adherence interventions and also provide directions for future research on PrEP among AYA.

Abstract
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.
