RESUMO

Adolescent girls and young women (AGYW) in Eastern and Southern Africa face parallel epidemics of unintended pregnancy and HIV. Their sexual health decisions are often dominated by intersecting stigmas. In an implementation science project integrating delivery of daily, oral pre-exposure prophylaxis (PrEP) for HIV prevention into 14 post-abortion care (PAC) clinics in Kenya, we enrolled a subset of PrEP initiating AGYW (aged 15 to 30 years) into a research cohort. Utilizing log binomial models, we estimated the effect of PrEP stigma on PrEP continuation (measured via self-report and urine assay for tenofovir) and abortion stigma on contraceptive initiation. Between April 2022 and February 2023, 401 AGYW were enrolled after initiating PrEP through their PAC provider, of which 120 (29.9%) initiated highly-effective contraception. Overall, abortion and PrEP stigmas were high in this cohort. Abortion stigma was more prevalent among those that were adolescents, unmarried, and reported social harm. Among 114 AGYW returning for the month 1 follow-up visit, 83.5% reported continuing PrEP and 52.5% had tenofovir detected. In this subset, higher levels of PrEP stigma were significantly associated with greater likelihood of PrEP adherence, but not PrEP continuation. For abortion stigma, greater scores in the subdomain of isolation were significantly associated with greater likelihood of initiating a highly-effective contraception, while greater scores in the subdomain of community condemnation were significantly associated with reduced likelihood of initiating a highly-effective contraception. Given the burden of stigma documented by our work, PAC settings are a pivotal space to integrate stigma-informed counseling and to empower young women to optimize contraceptive and PrEP decisions.

RESUMO

Adolescent girls and young women (AGYW) in South Africa are at a three times higher risk of acquiring HIV than their male counterparts. The HIV prevention cascade is a tool which can be used to measure coverage of HIV prevention services, although there is limited empirical evidence to demonstrate its application in low-resourced settings. The unifying framework is a conceptualisation of the HIV prevention cascade which theorises that both motivation and access are required for an individual to effectively use an HIV prevention method. We applied this framework to data from a random sample of 127,951 beneficiaries of a combination HIV prevention programme for AGYW aged 15-24 in South Africa to measure the steps to, and identify key barriers to, effective use of male condoms and oral pre-exposure prophylaxis (PrEP) among this vulnerable population. Barriers to each step were analysed using univariate and multivariable logistic regression. Among self-reported HIV-negative AGYW who had sex in the past 6 months, effective use of condoms (15.2%), access to PrEP (39.1%) and use of PrEP (3.8%) were low. AGYW were: less likely to be motivated to use condoms if they believed that they had a faithful partner (aOR 0.44, 95% CI 0.22-0.90) or disliked condoms (aOR 0.26, 95% CI 0.11-0.57), less likely to access condoms if the place where AGYW accessed them was far away (aOR 0.25, 95% CI 0.10-0.64), more likely to effectively use condoms if they received counselling on how to use them (aOR 2.24, 95% CI 1.05-4.76), less likely to be motivated to use PrEP if they did not believe PrEP was efficacious (aOR 0.35, 95% CI 0.17-0.72), more likely to be motivated if they felt confident that they could use PrEP, and more likely to have access to PrEP if they had ever been offered PrEP (aOR 2.94, 95% CI 1.19-7.22). This combination HIV prevention programme and similar programmes should focus on risk-reduction counselling interventions for AGYW and their male partners to improve effective use of condoms and ensure easy access to condoms and PrEP by making them available in youth-friendly spaces. Our findings demonstrate that the application of HIV prevention cascades can inform AGYW HIV prevention programming in low-resourced settings.

RESUMO

Pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV acquisition. We aimed to estimate usage of oral-PrEP, and factors associated with adherence among female sex workers (FSWs) in Nairobi, Kenya, using a novel point-of-care urine tenofovir lateral flow assay (LFA). The Maisha Fiti study randomly selected FSWs from Sex Worker Outreach Program clinics in Nairobi. Data were collected from 1003 FSWs from June-October 2019, including surveys on self-reported oral-PrEP adherence. Adherence was also measured using the LFA for HIV-negative FSWs currently taking oral-PrEP. Informed by a social-ecological theoretical framework, we used hierarchical multivariable logistic regression models to estimate associations between individual, interpersonal/community, and structural/institutional-level factors and either self-reported or LFA-assessed adherence. Overall, 746 HIV-negative FSWs aged 18-40 participated in the study, of whom 180 (24.1%) self-reported currently taking oral-PrEP. Of these, 56 (31.1%) were adherent to oral-PrEP as measured by LFA. In the multivariable analyses, associations with currently taking oral-PrEP included having completed secondary education, high alcohol/substance use, feeling empowered to use PrEP, current intimate partner, no recent intimate partner violence, having support from sex worker organisations, experiencing sex work-related stigma, and seeking healthcare services despite stigma. Associations with oral-PrEP LFA-measured adherence measured included having only primary education, experience of childhood emotional violence, belonging to a higher wealth tertile, and being nulliparous. Oral-PrEP adherence, measured by self-report or objectively, is low among FSWs in Nairobi. Programs to improve oral-PrEP usage among FSWs should work to mitigate social and structural barriers and involve collaboration between FSWs, healthcare providers and policymakers.

RESUMO

The Tu'Washindi intervention addressed intimate partner violence (IPV) and relationship dynamics to increase PrEP use among adolescent girls and young women (AGYW) in Siaya County, Kenya. We evaluated feasibility and acceptability in a cluster-randomized trial in six DREAMS Safe Spaces. The multilevel intervention, delivered over 6 months, included three components delivered by DREAMS staff with support from the study team: an 8-session structured support club; community sensitization of male partners; and a couples PrEP education and health fair ("Buddy Day"). Feasibility and acceptability assessments included implementation process measures, questionnaires, and focus group discussions with AGYWs and post-intervention questionnaires with intervention providers. The study included 103 AGYWs aged 17 to 24 (N = 49 intervention), with 97% retention. Median age was 22, 54% were married, and 84% were mothers. At enrollment, 45% used PrEP and 61% reported lifetime IPV. All intervention participants attended at least one support club session (mean = 5.2 of 8) and 90% attended Buddy Day. At 6 months, most participants perceived Tu'Washindi to be effective: all agreed (with 54% reporting "strongly agree") that the intervention improved partner communication and 60% agreed they were better able to gain partner support for their PrEP use. Providers believed the intervention resonated with community values. Tu'Washindi was highly acceptable and feasible and it was perceived by AGYW participants and providers as being effective in improving partner relationships and supporting PrEP use.

RESUMO

BACKGROUND: Zambian adolescent girls and young women (AGYW) have high HIV incidence and face barriers to the use of pre-exposure prophylaxis (PrEP). Parental support improves PrEP use and adherence in some settings, but negative parental attitudes toward HIV prevention may inhibit engagement with AGYW. We explored perceptions of future PrEP methods among AGYW and parents and parent-youth engagement on HIV prevention and PrEP use. METHODS: We conducted a qualitative descriptive study among AGYW and parents of AGYW in five provinces in Zambia in September-October 2021. We conducted 10 focus group discussions (FGDs) and four in-depth interviews (IDIs) with AGYW participants (n = 87) and seven FGDs and four IDIs among parents of AGYW (n = 62). All FGDs and IDIs were audio-recorded, transcribed verbatim, and analyzed to identify qualitative themes. RESULTS: Most AGYW participants preferred the discreet nature and longer duration of injectable PrEP compared to the PrEP ring and oral PrEP. Many AGYWs reported inability to disclose PrEP use to their parents due to lack of parental support based on cultural taboos against premarital sex. Nevertheless, AGYW participants said they would like to talk to their parents about PrEP so their parents could support their use. Many parents also described difficulties discussing PrEP with their daughters because of cultural and religious beliefs about abstinence from sex before marriage. However, parents acknowledged that the threat of HIV is real and said they need PrEP knowledge and guidance on speaking with their children about HIV prevention and PrEP. CONCLUSIONS: Although many parents are currently not playing a role in daughters' decisions about PrEP use, both parents and AGYW are willing to engage with each other on HIV prevention issues. To foster parent-child engagement, HIV prevention programs should not only provide information about PrEP but also address social norms that impede discussion of HIV prevention and equip both parents and AGYW with skills and support for such conversations. Community sensitization is also needed as new PrEP products are introduced, to create an enabling environment for parent-child engagement by increasing awareness, countering misconceptions, and reducing stigma.

RESUMO

BACKGROUND: Age-mixing (age-disparate [5-9 years difference] and intergenerational [≥ 10 years difference]) partnerships are hypothesized drivers of HIV in adolescent girls and young women (AGYW; 15-24 years). These partnerships are often associated with increased gender inequities which undermine women's agency and assertiveness. We assessed whether age-mixing partnerships were associated with HIV in Malawi and if endorsement of inequitable gender norms modifies this relationship. METHODS: We analyzed data from the Malawi Population-based HIV Impact Assessment, a nationally representative household survey conducted in 2015-2016. Participants underwent HIV testing and completed questionnaires related to actively endorsed gender norms and sexual risk behavior. We used multivariate logistic regression and multiplicative interaction to assess associations among AGYW who reported the age of their primary sex partner from the last year. RESULTS: The analysis included 1,958 AGYW (mean age = 19.9 years, SD = 0.1), 459 (23.4%) and 131 (6.7%) of whom reported age-disparate and intergenerational partnerships, respectively. AGYW in age-mixing partnerships accounted for 13% of all AGYW and were older, more likely to reside in urban areas, to be married or cohabitating with a partner, and to have engaged in riskier sexual behavior compared with AGYW in age-concordant partnerships (p < 0.05). HIV prevalence among AGYW in age-disparate and intergenerational partnerships was 6.1% and 11.9%, respectively, compared with 3.2% in age-concordant partnerships (p < 0.001). After adjusting for residence, age, education, employment, wealth quintile, and ever been married or cohabitated as married, AGYW in age-disparate and intergenerational partnerships had 1.9 (95% CI: 1.1-3.5) and 3.4 (95% CI: 1.6-7.2) greater odds of HIV, respectively, compared with AGYW in age-concordant partnerships. Among the 614 (31% of the study group) who endorsed inequitable gender norms, AGYW in age-disparate and intergenerational partnerships had 3.5 (95% CI: 1.1-11.8) and 6.4 (95% CI: 1.5-27.8) greater odds of HIV, respectively, compared with AGYW in age-concordant partnerships. CONCLUSIONS: In this Malawi general population survey, age-mixing partnerships were associated with increased odds of HIV among AGYW. These findings highlight inequitable gender norms as a potential focus for HIV prevention and could inform interventions targeting structural, cultural, and social constraints of this key group.

RESUMO

In Southern and Eastern Africa, initiation of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been high among adolescent girls and young women (AGYW) offered PrEP. However, persistence and prevention-effective use of PrEP among this critical group continues to be a challenge. We conducted a qualitative sub-study of AGYW from the Community PrEP Study in Eastern Cape Province, South Africa who had high rates of pick up for monthly PrEP refills over two years, but differing levels of PrEP adherence based on tenofovir-diphosphate (TFV-DP) measurements in dried blood spots (DBS). Contrasting 22 AGYW with low versus high levels of TFV-DP in DBS, we qualitatively explored factors which influenced PrEP persistence vs. non-persistence, unique patterns of PrEP use (e.g., discarding or stockpiling), and participant recommendations for improving AGYW prevention-effective use of PrEP in the future. Results showed that PrEP misconceptions and mistrust among participants' social networks negatively influenced adherence. In comparison, supportive families and/or partners and personal trust that PrEP works positively influenced adherence. Those with low adherence described being motivated to come to the site for other study benefits (e.g., reimbursement money, snacks, sanitary pads) and discarding PrEP to avoid stigma associated with being seen with pills. Future PrEP implementation strategies should focus on involving families and partners in PrEP support for AGYW and minimizing PrEP stigma at a community level.Trial registration NCT03977181.

RESUMO

BACKGROUND: Access and use of contraception services by adolescent girls and young women (AGYW) remains suboptimal, exposing AGYW to early and often unexpected pregnancy. Unexpected pregnancies are a public health concern, associated with poor neonatal and maternal health outcomes, as well as school dropout, which may result in economic hardships. This study aimed to explore (a) AGYW perceptions and experiences of receiving contraception services from health care providers and (b) health care providers' perceptions and experiences of providing contraception services to AGYW. METHODS: Data were collected through semi-structured individual interviews with AGYW aged 15-24 years old and health care providers working in eight health care facilities around the Cape Town metropolitan area, in South Africa's Western Cape Province. Thematic analysis was used to analyse the data. RESULTS: AGYW and health care providers voiced varying, and often contrasting, perceptions of some of the barriers that hinder AGYW's access to contraception services. AGYW indicated that provider-imposed rules about when to access contraceptive services hindered access, while health care providers felt that these rules were necessary for coordinating their work. In addition, AGYW highlighted health care providers' hostile attitudes towards them as an important factor discouraging access. On the contrary, health care providers did not think that their attitudes hampered AGYW's access to and use of contraception services, instead they emphasised that challenges at the health system level were a major issue, which they feel they have little control over. Such challenges made health care providers' work unpleasant and frustrating, impacting on their work approach and how they receive and offer services to AGYW. CONCLUSION: The expectation of negative attitudes from health care providers continues to be at the centre of AGYW discouragement towards accessing contraception services. System challenges are among some of the key drivers of health care provider's hostile attitudes, posing challenges to the efficient provision of services. In order to improve AGYW's access to and use of contraception services, and subsequently achieve the country's SDGs, conscious efforts need to be directed towards improving the workload and working conditions of health care providers.

RESUMO

Low perceived HIV risk is a barrier to effective pre-exposure prophylaxis (PrEP) use among African adolescent girls and young women (AGYW). Single-item risk perception measures are stigmatizing and alienating to AGYW and may not predict PrEP use. There is a need for a tool capturing domains of perceived HIV risk and salience that align with PrEP use among AGYW. This HIV PrEP study was conducted in Kampala, Uganda. We developed and piloted the 9-item "HIV Salience and Perception" (HPS) scale (range: 9-36); higher scores indicate beliefs of higher vulnerability to HIV. We administered the scale to Ugandan AGYW participating in an ongoing cohort study at enrollment, one, three and six months. PrEP dispensing was measured quarterly and adherence was measured daily via Wisepill (high adherence: ≥80% of expected pill bottle openings). We assessed scale performance and used generalized estimating equations to determine associations between scale score and PrEP use. Among 499 AGYW, 54.1% of our sample was ≥ 20 years (range:16-25). The median HPS score was 18 (range:8-33; α = 0.77). Higher score was associated with PrEP dispensing (aRR = 1.07 per point increase; 95% CI = 1.01-1.13; p-value = 0.02) in the overall cohort and among only those ≥ 20 years (aRR = 1.10; 95% CI = 1.03-1.19; p-value = 0.01). We did not observe an association between scale score and PrEP adherence. AGYW scoring higher on a novel HPS scale were more likely to initiate and obtain PrEP refills through 6 months. This scale may capture drivers of PrEP dispensing and could inform PrEP delivery and counseling for AGYW.

RESUMO

Daily oral pre-exposure prophylaxis (PrEP) is highly efficacious for HIV prevention. Adolescent girls and young women (AGYW) have been prioritised for PrEP delivery in South Africa. A combination HIV prevention intervention providing integrated biomedical, behavioural and structural interventions for AGYW aged 15-24 in twelve districts in South Africa characterised by high HIV prevalence, was implemented 2019-2022. We conducted qualitative interviews to explore PrEP implementation experiences with 38 individuals involved in the implementation of the combination HIV prevention programme, including programme managers and project coordinators, health care providers / nurses, social workers, counsellors, peer group trainers and outreach workers. Narratives included various challenges associated with PrEP uptake, adherence and acceptability experienced by implementers. Barriers to PrEP acceptability included AGYW fears of side effects and preference for injectable versus daily oral PrEP; resistance towards PrEP from AGYW, communities and parents due to a lack of accurate information; PrEP stigma linked to associations with antiretrovirals and assumptions of promiscuity; and issues pertaining to parental consent. Additionally, implementers faced logistical challenges related to procurement, stockouts, and supply of PrEP. Findings highlighted the critical role of parental and community acceptability of PrEP for successful implementation. Overall, PrEP was perceived by implementers as a valuable HIV prevention tool. In order to ensure the accessibility of PrEP for AGYW in South Africa, efforts to reduce stigma and foster social support for PrEP use, campaigns to raise awareness, ensure positive framing of PrEP, and build community acceptability of PrEP, are needed.

RESUMO

Adolescent girls and young women (AGYW) in sub-Saharan Africa are disproportionately affected by the human immunodeficiency virus (HIV) due to socio-cultural gender, power, and economic disparities. This scoping review examined the literature to explore what is known about AGYW's everyday personal, relational, and social experiences of HIV to help shape future protective HIV policy and practice. Six databases were searched: Medline, CINAHL, Scopus, ASSIA, Google Scholar, and ProQuest, resulting in a total of 12,581 articles. Of these, 40 articles were included in the review. Key themes generated from the thematic analysis were relational and psychosocial challenges, inhibiting sexual expression, poverty, stigma, and discrimination; managing health in everyday life; agency and resilience; and personal space and social support. In conclusion, the review found a lack of understanding of AGYW's everyday experiences of living with HIV from their own perspectives. There was also little consideration of the role of patriarchal culture and how this constrains AGYW's ability to negotiate their relationships. Further research is needed to reveal AGYW's perspectives on living with HIV in sub-Saharan Africa.

RESUMO

Adolescent girls and young women (AGYW) living with HIV have poor antiretroviral therapy (ART) outcomes. We examined the relationship between psychosocial factors with knowledge of HIV-positive status and antiretroviral therapy exposure among AGYW living with HIV in South Africa. Participants 15-24 years responded to a survey including socio-demographics, psychosocial factors, and HIV testing. Blood was collected to determine HIV status and ART exposure. Multivariable analyses were conducted using R. Of 568 participants with HIV, 356 had knowledge of their HIV-positive status. Social support from family [aOR 1.14 (95% CI 1.04-1.24)] or from a special person [aOR 1.12 (95% CI 1.02-1.23)] was associated with knowledge of HIV-positive status. Resilience [aOR 1.05 (95% CI 1.01-1.08)] was the only psychosocial factor associated with a higher odds of ART exposure. Social support and resilience may increase knowledge of HIV-positive status and ART exposure among South African AGYW.

RESUMO

To develop effective PrEP adherence interventions, it is important to understand the interplay between disclosure of pre-exposure prophalxis (PrEP) use, social support, and PrEP adherence. We leveraged the HPTN 082 study conducted among 451 adolescent girls and young women (AGYW) (ages 16 to 25 years, 2016 to 2019) in South Africa and Zimbabwe. Among the 349 who had month three disclosure and PrEP adherence data, 60% (n = 206) felt supported by adults, and 89% (n = 309) disclosed PrEP use to at least one person. PrEP disclosure was not associated with increased adherence, measured by intracellular tenofovir-diphosphate concentrations in dried blood spots. Women who reported having supportive adults, and disclosed to their parents, had higher adherence at 6 months with an increase of 177 fmol/punch (95% CI 12 to 343, t = 2.11, p = 0.04). PrEP interventions that help AGYW identify supportive relationships and effectively communicate the benefits of PrEP may improve PrEP adherence.Clinicaltrials.gov ID number: NCT02732730.

RESUMO

Adolescent girls and young women (AGYW) account for 25% of new HIV infections in South Africa. Pre-exposure prophylaxis (PrEP) is approved by the South African Government, but the factors that promote PrEP uptake among AGYW are not well understood. This study examines multilevel factors associated with PrEP uptake among AGYW in six clinic catchment areas in Tshwane (Pretoria), South Africa. After consent/assent, PrEP-eligible AGYW (n = 448) completed a questionnaire assessing factors at the individual, network/interpersonal, and community levels and were prescribed PrEP in study clinics, if interested. A multivariable model, adjusting for clustering, assessed factors associated with PrEP uptake over a 9-month period. At the individual level, multiple partners in the past 3 months (OR = 0.47), perceived risk of HIV (OR = 0.71), and PrEP-related shame (OR = 0.63) were correlated with lower odds of PrEP uptake (ps ≤ 0.05). The findings highlight modifiable factors that should be addressed to support PrEP uptake efforts.

RESUMO

Effective use of oral pre-exposure prophylaxis (PrEP) has been low among adolescent girls and young women (AGYW) in Eastern and Southern Africa, partly due to stigma and opposition from key influencers. Understanding AGYW's experiences of disclosure of different PrEP modalities to key influencers may inform strategies to motivate uptake and adherence. We analyzed qualitative in-depth interviews and focus group discussions data from 119 participants in the MTN-034/REACH (Reversing the Epidemic in Africa with Choices in HIV Prevention) study of oral PrEP and the dapivirine vaginal ring (ring) to explore AGYW's disclosure experiences. We found that AGYW disclosure experiences varied across influencers and product type. The ring was disclosed less often to most influencers, except partners, because it was discreet. Oral PrEP was disclosed more often, because pills were more common and to avoid HIV stigma given that oral PrEP resembled HIV treatment. Ultimately, disclosure typically led most key influencers to support product use through reminders and encouragement. While disclosure yielded positive support from influencers, further community awareness of both PrEP products is essential to reduce potential opposition and perceived stigma.Clinical Trial Number: NCT03593655.

RESUMO

Adolescent girls and young women (AGYW) engaging in sex-for-money transactions are at risk of HIV infection. A better understanding of the demographic, socio-economic factors and risks of HIV acquisition is required to guide appropriate public health interventions targeting young sex workers in South Africa. A cross-sectional survey of Female Sex Workers (FSWs), using a chain referral sampling method, was conducted across 12 sites in South Africa in 2019. Three thousand and five participants were enrolled and interviewed assessing demographic characteristics, sexual behaviour, substance use and HIV testing and treatment. Of 3005 women, 13.3% were ≤24 years old (young FSWs); of these, 60.0% entered sex work aged ≤19 years. Economic factors were the primary drivers of entry into sex work. HIV prevalence amongst young FSWs was 40.4%, with 12.4% recently infected. Younger FSWs were significantly less likely to know they were HIV positive (87.6% versus 92.1%), to report any ART exposure (75.2% versus 87.6%) and to be virally suppressed (58.1% versus 75.2%) compared to older FSWs. Our findings highlight that many FSWs enter sex work at a young age. It is essential to develop tailored services and interventions that improve access to HIV prevention and treatment services addressing specific needs.

RESUMO

BACKGROUND: Adolescent girls and young women (AGYW) have a high incidence of unplanned pregnancies, especially in low-resource settings. AGYW assess the overlapping risks of pregnancy, contraception, and STIs as they navigate relationships. Few studies have examined how AGYW consider the comparative risks of their decisions around sexual and reproductive health in this context or how risk perception influences contraceptive use. METHODS: Twenty in-depth interviews (IDIs) and 5 focus group discussions (FGDs) were conducted with a subset of sexually active AGYW enrolled in the Girls Health Study (GHS), a longitudinal cohort study in Thika, Kenya, assessing HSV-2 incidence in a cohort of AGYW aged 16-20. Interview questions were focused on perspectives and decision-making around sexual and reproductive health. Interviews were conducted in both English and Kiswahili, transcribed, and coded using inductive and deductive approaches to identify emerging themes. RESULTS: Misconceptions about long-acting reversible contraceptives (LARCs), injectables, and daily oral contraceptive pills strongly disincentivized their use among AGYW. Participants described pregnancy as undesirable, and AGYW reported prioritizing contraceptive methods that were effective and reliable in pregnancy prevention, even if not effective in preventing STI/HIV infection. Participants reported that AGYW relied heavily on emergency contraceptive (EC) pills for pregnancy prevention. CONCLUSIONS: Though the goal of avoiding unintended pregnancy was common, this did not suffice to motivate the uptake of long-term contraceptives among AGYWs. Given the convenience, cost-effectiveness, and lower perceived risk of side effects, EC pills were more likely to be accepted as a form of contraception. Understanding the reasons for AGYW's acceptance of certain contraceptive methods over others can help future interventions better target communication and counseling about contraception and influence key drivers of AGYW behavior and decision-making around sexual and reproductive health.

RESUMO

BACKGROUND: Trust is an important cornerstone of patient-provider communication. Accurate reporting of pre-exposure prophylaxis (PrEP) adherence is vital for providers to determine who needs adherence support, especially adolescent girls and young women (AGYW) disproportionately affected by newly diagnosed HIV. METHODS: This is a secondary analysis of the HPTN 082 open-label PrEP demonstration trial. From 2016-2018, 451 AGYW aged 16-25 years were enrolled in South Africa (Cape Town and Johannesburg) and Zimbabwe (Harare). PrEP was initiated by 427, and 354 (83%) had month three patient-reported adherence responses and intracellular tenofovir diphosphate (TFV-DP) measurements. The patient-reported adherence response to 'In the past month, how often did you take the tablet?' was dichotomized as 'high' if the response was every day or most days, and 'low' if some days or not many days or never. The biomarker marker evidence of adherence in dried blood spots was defined as 'high' if TFV-DP ≥ 700, and 'low' if < 350 fmol/punch. We used multinomial logistic regression to examine if trust in the PrEP provider was associated with concordance between patient-reported adherence and intracellular tenofovir-diphosphate (TFV-DP). RESULTS: AGYW who reported trust in their providers were almost four-fold (aOR 3.72, 95% CI 1.20-11.51) more likely to have concordant adherence (high self-reported adherence and high TFV-DP concentrations) compared to discordant non-adherence (high self-reported adherence and low TFV-DP concentrations). CONCLUSION: Education and training of providers to build trusting relationships with AGYW may lead to more accurate reporting of PrEP adherence. With accurate reporting, adequate support can be provided to bolster adherence. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02732730.

RESUMO

INTRODUCTION: Adolescent girls and young women (AGYW) in Nepal have disproportionately poor reproductive and maternal health outcomes. In response, Save the Children, the Nepal government, and local partners designed and implemented Healthy Transitions for Nepali Youth, a multi-level integrated intervention. The intervention aimed to improve reproductive, maternal, and newborn health knowledge, attitudes, and behaviors among AGYW, and address gender attitudes and norms in four districts of Karnali Province, Nepal. METHODS: Married and unmarried AGYW aged 15-24 were engaged in a small group, curriculum-based intervention; husbands and families received home visits, using short videos to catalyze discussion; communities were engaged through dialogue-based activities; and the health system was made more adolescent-responsive through quality assessments, training, and supervision. An external organization conducted a quantitative survey with a sample of 786 AGYW intervention participants at baseline and 565 of the same AGYW at endline. Pooled linear regressions were estimated for each indicator to assess the statistical significance of differences between baseline and endline. Focus group discussions and key informant interviews were conducted with AGYW, husbands, families, community leadership, and program implementers. Data analysis was done through STATA 14th version and NVivo. RESULTS: The percentage of AGYW currently using a modern contraceptive method increased significantly, and more AGYW believed that their family was supportive of delaying marriage and motherhood at the endline. Young women's knowledge of danger signs during labor increased, and there was a significant improvement in essential newborn care practices immediately after birth. AGYW reported shifts towards more gender equitable attitudes and behaviors, including related to decision-making about reproductive and maternal health. CONCLUSION: Positive shifts in reproductive, maternal, and newborn health and gender knowledge, attitudes, and behavior were observed among AGYW, their male partners, and families. The results can inform the design of future interventions to effectively reach this critical population. TRAIL REGISTRATION: Not applicable.

RESUMO

BACKGROUND: Condom use among young people in South Africa has declined in recent years and adolescent girls and young women continue to bear the highest incidence of HIV in the country. Young women who have dropped out of school may be more at risk because of traditional gender norms that create substantial power imbalances and a lack of power to negotiate condom use with their male partners, especially when using alcohol and other drugs. METHODS: This study presents an analysis of baseline data provided by 500 adolescent girls and young women (AGYW) from Cape Town communities between November 2016 and November 2018 who were reached for a cluster-randomised trial conducted to assess the efficacy of an evidence-based, young woman-focused intervention seeking to reduce HIV risk and substance use behaviours. The analysis focuses on associations between binge drinking, condom use, and sexual negotiation, including impaired sex (any substance use at last sex). RESULTS: AGYW who reported frequent condom negotiation with their partners were 8.92 times (95% CI: [4.36, 18.24]) as likely to use a condom when alcohol or other drugs were not used at last sex and 5.50 times (95% CI: [2.06, 14.72]) as likely when alcohol or other drugs were used at last sex (p < 0.05). AGYW who reported frequent binge drinking in the past month (n = 177) had significantly reduced odds of condom use at last sex, irrespective of whether the sex was impaired (OR 0.60, 95% CI: [0.49, 0.73]) or not impaired (OR 0.69, 95% CI: [0.60, 0.81]). DISCUSSION: The findings highlight the need for interventions that reach AGYW in South Africa by specifically aiming to educate AGYW about the effect of binge drinking on negotiating power in their relationships, thus providing them with the knowledge and skills to increase agency regarding condom use.
