"Project YES! has given me a task to reach undetectable": Qualitative findings from a peer mentoring program for youth living with HIV in Zambia.

The Project YES! clinic-based peer mentoring program was a randomized controlled trial (RCT) conducted among 276 youth from four HIV clinics to test the impact of the program on promoting HIV self-management and reducing internalized stigma among youth living with HIV (ages 15-24 years) in Ndola, Zambia. We conducted a qualitative sub-study involving in-depth interviews with 40 intervention youth participants (21 female, 19 male) to explore their experiences with Project YES! which included: an orientation meeting led by a healthcare provider, monthly individual and group counseling sessions over six months, and three optional caregiver group sessions. Using baseline RCT data, we used maximum variation sampling to purposively select youth by sex, age, change in virologic results between baseline and midline, and study clinic. A four-person team conducted thematic coding. Youth described their increased motivation to take their HIV care seriously due to Project YES!, citing examples of improvements in ART adherence and for some, virologic results. Many cited changes in behavior in the context of greater feelings of self-worth and acceptance of their HIV status, resulting in less shame and fear associated with living with HIV. Youth also attributed Project YES! with reducing their sense of isolation and described Project YES! youth peer mentors and peers as their community and "family." Findings highlight that self-worth and personal connections play a critical role in improving youths' HIV outcomes. Peer-led programs can help foster these gains through a combination of individual and group counseling sessions. Greater attention to the context in which youth manage their HIV, beyond medication intake, is needed to reach global HIV targets.

The association between violence victimization and subsequent unplanned pregnancy among adolescent girls in Uganda: Do primary schools make a difference?

Violence victimization is a risk factor for adolescent pregnancy in high-income, low violence prevalence countries, but longitudinal data are lacking from settings where violence and adolescent pregnancy are common, including sub-Saharan Africa. We also know little about contextual factors which modify this association. We analyzed data from the Contexts of Violence in Adolescence Cohort (CoVAC) study in Luwero District, Uganda. Primary students in 42 schools completed surveys in 2014 (Wave 1) and 2018 (Wave 2). Our outcome was unplanned pregnancy. Our exposure was violence victimization, including any violence, type of violence (physical, emotional, sexual), perpetrator group (teacher, peer, family member), and polyvictimization. We fit mixed-effects logistic regression models and examined school factors (e.g., connectedness, absenteeism) as effect modifiers, using data from students (n = 3,431) and staff (n = 591) at the 42 schools. 1,449 girls were included in analyses (78% follow-up). At Wave 1, 88% (n = 1,281/1,449) reported any violence (mean age = 12.73, SD = 1.44 years). At Wave 2, 13.9% (n = 201/1,449) reported an unplanned pregnancy. In adjusted models, compared to no violence, significant associations (p<0.05) were observed for any violence (OR = 1.99, 95%CI = 1.03-3.85), physical violence (OR = 1.96, 95%CI = 1.02-3.79), teacher violence (OR = 1.96, 95%CI = 1.01-3.79), peer violence (OR = 2.00, 95%CI = 1.00-4.03), family violence (OR = 2.23, 95%CI = 1.07-4.65), violence from one perpetrator group (OR = 2.04, 95%CI = 1.01-4.15), and violence from three perpetrator groups (OR = 2.21, 95%CI = 0.99-4.95). Sexual and emotional violence were associated in crude but not adjusted analyses. School and peer connectedness modified the association (p<0.05); girls who experienced violence had higher odds of unplanned pregnancy in schools with lower versus higher connectedness. Violence victimization in early adolescence is strongly associated with subsequent unplanned pregnancy among adolescent girls in Uganda but attending schools with more school or peer connectedness attenuated this link. Interventions should seek to reduce violence against girls to prevent unplanned pregnancy. Interventions promoting positive connections to school may be especially important for violence victims.

Preliminary effectiveness and implementation outcomes of the IMARA-South Africa sexual health intervention on adolescent girls and young women: A pilot randomized trial.

Family-based interventions may help reduce the risk of HIV and other sexually transmitted infections (STI) among adolescent girls and young women (AGYW) in sub-Saharan Africa but few have been tested. We examined the preliminary effectiveness and implementation outcomes of Informed, Motivated, Aware, and Responsible Adolescents and Adults-South Africa (IMARA-SA), an evidence-based intervention for South African AGYW (15-19 years) and their female caregivers. We piloted IMARA-SA in the Western Cape using an individually randomized experimental design and average follow-up at 11 months. Primary outcomes were HIV Testing and Counselling (HTC) uptake, STI incidence (gonorrhea, chlamydia), and pre-exposure prophylaxis (PrEP) uptake. Secondary outcomes were self-reported sexual risk behavior (condom use at last sex, consistency of condom use, substance use during sex, and number of sexual partners) and PrEP adherence. We examined four implementation outcomes: reach, feasibility, acceptability, and fidelity. Data from 59 AGYW (mean = 17.2 years) were analyzed at baseline (n = 29 from IMARA-SA, 30 from a health promotion control group). At follow-up, 51 (86%) completed surveys and 39 (66%) presented for HTC, STI testing, and/or PrEP. Compared to controls, fewer IMARA-SA participants tested positive for an STI (22% versus 38%), more IMARA-SA participants took up PrEP (68% versus 45%), and four of five secondary outcomes favored the IMARA-SA group at follow-up. These differences did not reach statistical significance. HTC uptake at follow-up was 100% in both groups. All AGYW-FC dyads agreed to participate in the study (reach). In the IMARA-SA group, 76% of dyads completed the intervention (feasibility), and over 76% of acceptability ratings from AGYW and their FC had the highest Likert rating. Fidelity of intervention delivery was 95%. IMARA-SA is a promising strategy for reducing HIV/STI risk among South African AGYW. We found strong evidence of reach, feasibility, acceptability, and fidelity. A fully powered randomized controlled trial is warranted.

Harmonizing Implementation and Outcome Data Across HIV Prevention and Care Studies in Resource-Constrained Settings.

Harmonizing measures across studies can facilitate comparisons and strengthen the science, but procedures for establishing common data elements are rarely documented. We detail a rigorous, 2-year process to harmonize measures across the Prevention And Treatment through a Comprehensive Care Continuum for HIV-affected Adolescents in Resource Constrained Settings (PATC3H) consortium, consisting of eight federally-funded studies. We created a repository of measured constructs from each study, classified and selected constructs for harmonization, and identified survey instruments. Measures were harmonized for implementation science, HIV prevention and care, demographics and sexual behavior, mental health and substance use, and economic assessment. Importantly, we present our harmonized implementation science constructs. A common set of implementation science constructs have yet to be recommended in the literature for low-to-middle-income countries despite increasing recognition of their importance to delivering and scaling up effective interventions. Drawing on RE-AIM (Reach Effectiveness Adoption Implementation Maintenance) and the Implementation Outcomes Framework, items were harmonized for staff/administrators and study participants to measure reach, adoption, implementation, maintenance, feasibility, acceptability, appropriateness, and fidelity. The process undertaken to harmonize measures and the codified set of implementation science measures developed by our consortium can inform future data harmonization efforts, critical to strengthening the replication and generalizability of findings while facilitating collaborative research-especially in resource-limited settings. We conclude with recommendations for research consortia, namely ensuring representation from all study teams and research priorities; adopting a flexible, transparent, and systematic approach; strengthening the literature on implementation science harmonization; and being responsive to life events (e.g., COVID-19).

"It must start with me, so it started with me": A qualitative study of Project YES! youth peer mentor implementing experiences supporting adolescents and young adults living with HIV in Ndola, Zambia.

BACKGROUND: Little is known about youth-led approaches to addressing HIV-related outcomes among adolescents and young adults (AYA) living with HIV. In response, Project YES! hired and trained youth living with HIV as peer mentors (YPMs) in four HIV clinics in Ndola, Zambia to hold meetings with 276 15-24-year-olds living with HIV. Within this randomized controlled trial, a qualitative sub-study was conducted to explore YPMs' implementing experiences. METHODS: In-depth interviews were conducted with the eight YPMs (50% female) ages 21-26 years. YPMs were asked about their experiences working with clients, their feedback on program components, and what the experience meant to them personally and professionally. Interviews were audio-recorded, transcribed verbatim, and thematic analysis was performed. RESULTS: YPMs connected with AYA clients by discussing shared struggles, modeling positive health behaviors, and establishing judgement-free environments. YPMs experienced powerful personal transformations in HIV-related health behaviors, conceptions of self, and plans for the future. Many expressed now seeing themselves as community leaders-"ambassadors", "game changers"-and "not just alone in this world." They described newfound commitments to reaching personal and professional goals. YPMs were adamant that Project YES! should expand so other HIV-positive AYA might benefit. CONCLUSION: Well-trained and compensated YPMs who are integrated into HIV clinics can support AYA in unique and important ways due to their shared experiences. The transformational experience of becoming YPMs empowers youth to see themselves as role models and leaders. Future programs should engage youth living with HIV as partners in efforts to end the HIV epidemic.

'So hurt and broken': A qualitative study of experiences of violence and HIV outcomes among Zambian youth living with HIV.

Emerging data show associations between violence victimisation and negative HIV outcomes among youth in sub-Saharan Africa. We conducted in-depth interviews with adolescents and young adults living with HIV (aged 15-24 years) in Ndola, Zambia, to better understand this relationship. We purposively selected 41 youth (24 females, 17 males) with varied experiences of violence and virologic results. Analysis used thematic coding. Two-thirds of participants said violence affected their medication adherence, clinic attendance, and/or virologic results. They focused on the negative effects of psychological abuse from family members in homes and peers at schools, which were the most salient forms of violence raised, and sexual violence against females. In contrast, they typically depicted physical violence from caregivers and teachers as a standard discipline practice, with few impacts. Youth wanted HIV clinic settings to address verbal abuse and emotional maltreatment, alongside physical and sexual violence, including through peer mentoring. Violence - especially verbal and emotional forms - must be recognised as a potential barrier to HIV self-management among youth living with HIV in the region. Further testing of clinic, home, and school-based interventions may be critical to reducing levels of violence and improving HIV outcomes in this vulnerable but resilient population.Trial registration: ClinicalTrials.gov identifier: NCT04115813.

Mental health outcomes of a pilot 2-arm randomized controlled trial of a HIV-prevention program for South African adolescent girls and young women and their female caregivers.

BACKGROUND: South African adolescent girls and young women (AGYW) report significant mental distress and sexual and reproductive health concerns. Mental health problems and trauma symptoms are consistently associated with sexual and reproductive health behavior. Despite their intersection, few interventions address them simultaneously or engage female caregivers (FC) as collaborators. This study presents findings from a pilot test of an empirically supported culturally adapted family-based HIV-prevention program, Informed Motivated Aware and Responsible Adolescents and Adults- South Africa (IMARA-SA), on AGYW anxiety, depression, and trauma. METHODS: Sixty 15-19-year-old AGYW (mean age = 17.1 years) and their FC from outside Cape Town were randomized to IMARA-SA or a health promotion control program. AGYW reported their anxiety using the GAD-7, depression using the PHQ-9, and trauma using the PC-PTSD-5 at baseline and follow-up (6-10 months post). Both interventions were delivered by Xhosa-speaking Black South African women in groups over 2 days for approximately 10 h. We examined intervention effects using zero-inflated negative binomial regression for anxiety, multinomial logistic regression for depression, and logistic regression for trauma. RESULTS: At baseline, groups did not differ in demographic characteristics but AGYW randomized to IMARA-SA had higher depression scores than controls (p = 0.04) and a greater proportion screened positive for PTSD (p = .07). Controlling for baseline mental health scores, AGYW who received IMARA-SA compared to controls had significantly fewer anxiety symptoms at follow-up (adjusted incidence rate ratio for count model = 0.54, 95% CI = 0.29-0.99, p = 0.05), were less likely to report at least one depressive symptom relative to no symptoms (relative risk ratio = 0.22, 95% CI = 0.05, 0.95, p = 0.04), and were less likely to report symptoms of PTSD relative to no symptoms, but this difference was not statistically significant. CONCLUSIONS: Mental health is implicated in risky sexual behavior, and reducing emotional distress can mitigate exposure to poor sexual and reproductive health outcomes. This pilot study yielded promising findings for the mental health impact of IMARA-SA, justifying replication in a larger randomized trial.

Can the 'Learn in peace, educate without violence' intervention in Cote d'Ivoire reduce teacher violence? Development of a theory of change and formative evaluation results.

OBJECTIVES: To gather evidence on whether a brief intervention (Apprendre en paix et éduquer sans violence, developed by the Ivorian Ministry of Education and Graines de Paix) to promote peace in primary schools by reducing teacher violence perpetration and improving pedagogical techniques was acceptable to teachers and affected change in intermediate outcomes. DESIGN: Mixed-methods formative research. SETTING: Primary schools in Tonkpi region, Cote d'Ivoire. PARTICIPANTS: 160 teachers participating in the peace training, surveyed three times during implementation; qualitative in-depth interviews with 19 teachers and teacher-counsellors. INTERVENTIONS: Learn in peace, educate without violence-a brief intervention with primary school teachers designed to promote peace in primary schools. OUTCOMES: For survey data, we generated composite measures of intermediate outcomes (teachers' awareness of consequences of violence, self-efficacy in applying positive classroom management methods, acceptance of physical discipline practices in school) and used random intercept linear mixed-effects models to compare responses over time. Qualitative research included open-ended questions about acceptability and perceived need for such an intervention. A framework analysis was undertaken. RESULTS: Four-months post-training (vs pretraining), teachers had higher self-efficacy in applying positive classroom management methods (pre-mean=26.1; post-mean=27.5; p<0.001) and borderline lower acceptance of physical discipline practices (premean=4.2; postmean=3.6; p=0.10). We found no change in teacher awareness of the consequences of violence. Qualitatively, teachers found the intervention acceptable and understandable, perceiving it as useful because it provided methods for non-violent discipline. Teachers had mixed views about whether the techniques improved classroom dynamics. CONCLUSIONS: Data suggest that the intervention is acceptable and leads to change in intermediate outcomes for teachers. Further evaluation in a randomised controlled trial is warranted.

Experiences with a violence and mental health safety protocol for a randomized controlled trial to support youth living with HIV.

BACKGROUND: Safety protocols are an essential component of studies addressing violence and mental health but are rarely described in the published literature from Sub-Saharan Africa. We designed and implemented a safety protocol within Project YES! (Youth Engaging for Success), which enrolled 276 youth living with HIV (ages 15-24 years) in a randomized controlled trial of a peer-mentoring intervention across four HIV clinics in Ndola, Zambia. METHODS: Youth who reported severe violence and/or suicidal thoughts on research surveys or during meetings with youth peer mentors (YPM) were referred to designated healthcare providers (HCP). We explored experiences with the safety protocol using: a) monitoring data of referrals, and b) in-depth interviews with youth (n = 82), HCP (n = 10), YPM (n = 8), and staff (n = 6). Descriptive statistics were generated and thematic analysis of coded transcripts and written memos performed. RESULTS: Nearly half of youth enrolled (48% of females, 41% of males) were referred to a HCP at least once. The first referral was most often for sexual violence (35%) and/or suicidal ideation/depression (29%). All referred youth aged 15-17 years and over 80% of referred youth aged 18 + agreed to see a HCP. HCP referred 15% for additional services outside the clinic. Twenty-nine youth, all HCP, all YPM, and all staff interviewed discussed the safety protocol. Most youth felt "encouraged," "helped," "unburdened," and "relieved" by their meetings with HCP; some expressed concerns about meeting with HCP. The safety protocol helped HCP recognize the need to integrate care for violence and mental health with medication adherence support. HCP, YPM, and study staff raised implementation challenges, including youth choosing not to open up to HCP, time and resource constraints, deficiencies in HCP training, and stigma and cultural norms inhibiting referrals outside the clinic for emotional trauma and mental health. CONCLUSIONS: Implementing a safety protocol within an HIV clinic-based research study is possible and beneficial for youth and HCP alike. Implementation challenges underscore that HCP in Zambia work in over-stretched healthcare systems. Innovative strategies must address deficiencies in training and resources within HIV clinics and gaps in coordination across services to meet the overwhelming need for violence and mental health services among youth living with HIV.

An individually randomized controlled trial of a mother-daughter HIV/STI prevention program for adolescent girls and young women in South Africa: IMARA-SA study protocol.

BACKGROUND: South Africa has the world's largest HIV epidemic, but South African adolescent girls and young women (AGYW) acquire HIV at twice the rate of and seroconvert on average 5-7 years earlier than their male peers. Female caregivers (FC) are an untapped resource for HIV/STI prevention in South Africa and offer a novel opportunity to strengthen AGYW prevention efforts. This study will evaluate the effectiveness and cost-effectiveness of an evidence-based mother-daughter HIV/STI prevention program tested in the United States and adapted for South Africa, Informed Motivated Aware and Responsible Adolescents and Adults (IMARA), to decrease STI incident infections and increase HIV testing and counseling (HTC) and PrEP uptake in AGYW. METHODS: This is a 2-arm individually randomized controlled trial comparing IMARA to a family-based control program matched in time and intensity with 525 15-19-year-old Black South African AGYW and their FC-dyads in Cape Town's informal communities. AGYW will complete baseline, 6-, and 12-month assessments. Following randomization, AGYW-FC dyads will participate in a 2-day group workshop (total 10 h) that includes joint and separate mother and daughter activities. Primary outcomes are AGYW STI incidence, HTC uptake, and PrEP uptake at 6 months. Secondary outcomes are AGYW STI incidence, HTC uptake, and PrEP uptake at 12 months, sexual behavior (e.g., condom use, number of partners), HIV incidence, and ART/PrEP adherence and intervention cost-effectiveness. AGYW who test positive for a STI will receive free treatment at the study site. HIV positive participants will be referred to ART clinics. DISCUSSION: Primary prevention remains the most viable strategy to stem new STI and HIV transmissions. HIV and STI disparities go beyond individual level factors, and prevention packages that include supportive relationships (e.g., FC) may produce greater reductions in HIV-risk, improve HTC and PrEP uptake, and increase linkage, retention, and adherence to care. Reducing new HIV and STI infections among South African AGYW is global public health priority. TRIAL REGISTRATION: ClinicalTrials.gov Number NCT04758390 , accepted 02/16/2021.

"Adolescents do not only require ARVs and adherence counseling": A qualitative investigation of health care provider experiences with an HIV youth peer mentoring program in Ndola, Zambia.

INTRODUCTION: Adolescents and young adults (AYAs) living with HIV face unique challenges and have poorer health outcomes than adults with HIV. Project YES! was a youth-led initiative to promote HIV self-management and reduce stigma among AYAs in four Ndola, Zambia clinics. Clinic health care providers (HCPs) were involved in multiple intervention aspects, including serving as expert resources during AYA and caregiver group meetings, facilitating resistance test-based AYA antiretroviral drug changes, meeting with participants referred through a safety protocol, and guiding a subset of participants' physical transition from pediatric to adult clinic settings. This study aimed to understand HCP insights on facilitators and barriers to implementing Project YES! and scaling up a clinic-based, youth-focused program. METHODS: A trained interviewer conducted ten in-depth interviews with participating HCPs from November-December 2018 and analyzed data, identifying key themes. These themes were examined in terms of two implementation science outcomes-acceptability and feasibility-to inform scalability. RESULTS: HCPs found peer mentoring valuable for AYAs with HIV and the bimonthly caregiver meetings beneficial to AYA caregivers. HCPs voiced a desire for more involvement in specific processes related to patient clinical care, such as drug changes. HCPs' experiences with the study safety protocol, including referrals for youth experiences of violence, shifted their views of AYAs and informed their understanding of key issues youth face. Considering this, many HCPs requested more resources to support AYAs' varied needs. HCPs noted limited time and clinic space as implementation barriers but felt the program was valuable overall. CONCLUSIONS: HCPs concluded youth peer mentoring was highly acceptable and feasible, supporting scale-up of youth-led interventions addressing the multi-faceted needs of AYAs living with HIV. Continued provider involvement in resistance test-based antiretroviral drug changes, considered in the context of health system and clinic policy, would enhance long-term success of the program at scale.

Missed Opportunities for Addressing Intimate Partner Violence Through Microcredit: Qualitative Findings From Bangladesh.

Microcredit has shown mixed results when used to reduce intimate partner violence (IPV). This study explored microcredit and IPV in Bangladesh by conducting 12 focus groups with married men and women. Participants described challenges to microcredit participation highlighting "missed opportunities" for reducing IPV, including needs to (a) prevent violence sparked by loan disputes, (b) incorporate skill development to improve women's agency as a means of reducing IPV, and (c) mindfully engage men in the loan process to help address men's unequal gender ideologies. These modifications to microcredit programs are proposed to maximize positive change on gender and IPV.

Past-Year Violence Victimization is Associated with Viral Load Failure Among HIV-Positive Adolescents and Young Adults.

We examined the relationship between past-year violence victimization and viral load (VL) failure among consecutively-sampled male and female adolescents and young adults, aged 15-24, in four HIV clinics in Ndola, Zambia. Measures of past-year physical violence, psychological abuse, and forced sex were adapted from the ICAST-C and WHO Multi-Country Study. Using logistic regression, we derived associations between VL failure (≥ 1000 copies/mL) and: any victimization; cumulative victimization; and types and perpetrators of violence. Among 272 youth (59.2% female, 72.8% perinatally infected), 73.5% (n = 200) experienced past-year violence and 36.8% (n = 100) had VL failure. Higher odds of VL failure were observed for participants who reported high frequency of any violence versus no violence victimization (adjusted OR, aOR: 3.58; 95% CI 1.14-11.27), high frequency of psychological abuse versus no psychological abuse (aOR: 3.32; 95% CI 1.26-8.70), any versus no violence from a family member other than a parent/caregiver for physical violence (aOR: 2.18, 95% CI 1.05-4.54) and psychological abuse (aOR: 2.50; 95% CI 1.37-4.54), and any versus no physical violence from a friend/peer (aOR: 2.14, 95% CI 1.05-4.36). Past-year violence victimization was associated with VL failure when considering the frequency, type, and perpetrator of violence. Programs addressing violence among youth living with HIV may be critical to improving viral suppression and preventing onward transmission.

Measuring violence perpetration: Stability of teachers' self-reports before and after an anti-violence training in Cote d'Ivoire.

BACKGROUND: Epidemiological studies of interpersonal violence commonly use self-reported violence perpetration as an outcome measure, but few studies have investigated the stability of and influences on self-reports. OBJECTIVE: To assess changes in teachers' self-reported use of physical violence against students before and after a one-day violence prevention training, and factors associated with changed reports in Cote d'Ivoire. METHODS: Before and after the training, 157 teachers completed surveys containing 32 questions adapted from the ICAST-CI. Changes in physical violence usage were summarized over lifetime, past school term, and past-week timeframes, and the consistency in responses assessed via intraclass correlation coefficients (3,k), percent agreement, and kappa statistics. Factors associated with changed reports were assessed using robust multiple linear regression with 1,000 bootstrapped replications. RESULTS: Although reports before and after the training should have remained constant, the proportion of teachers reporting 1+ act of violence dropped substantially (lifetime: 73% to 47%). Most teachers (73%) changed 1+ response. Kappa for individual items showed ranging disagreement (lifetime: 0.275-0.795). Variables significantly associated with greater numbers of changed reports included: greater mental health distress (lifetime: beta = 1.061, 95% CI = 0.229, 2.404), older age (past school term: beta = 0.067, 95% CI = 0.018, 0.113); and variables targeted during training, including increasing awareness of consequences of violence (past week: beta = 0.241, 95% CI = 0.046, 0.435) and decreasing acceptance of physical discipline practices in schools (past school term: beta= -0.169, 95% CI= -0.338, -0.045). CONCLUSIONS: Interpreting self-reports of violence perpetration requires caution. Formal investigations into reliability and validity of self-reported violence perpetration and victimization are needed.

Prevalence of physical and sexual violence and psychological abuse among adolescents and young adults living with HIV in Zambia.

BACKGROUND: Little is known about violence against HIV-positive adolescents and young adults (AYA) in sub-Saharan Africa. This analysis examines experiences of violence victimization, and the perpetrators of this violence, among AYA living with HIV, aged 15-24 years, in Zambia. METHODS: We analyzed baseline data from 272 AYA (60.1% female, 71.0% perinatally infected) enrolled in Project YES! (Youth Engaging for Success), a randomized controlled trial conducted in four HIV clinics in Ndola, Zambia. Violence measures were adapted from the ICAST-C and the WHO Multi-Country Study on Women's Health and Domestic Violence. Youth could report up to 12 perpetrator types for past-year experiences of violence. We estimated lifetime and past-year prevalence of physical violence, psychological abuse, and forced sex, disaggregated by sex and age group. Estimates were weighted using sex and age data from the 2013-14 Zambian Demographic and Health Survey to be representative of HIV-positive AYA in Zambia. RESULTS: Estimated lifetime prevalence of any violence victimization was 78.2%. Past-year prevalence was 72.0% among males and 74.5% among females. Almost half of AYA (46.1%) had ever experienced polyvictimization (2+ types of violence). Psychological abuse was most common (70.4% lifetime, 65.3% past-year), followed by physical violence (50.8% lifetime, 44.7% past-year) and forced sex (10.4% lifetime, 4.7% past-year). Among past-year victims, males experienced more violence than females from a friend/peer (74.3% vs. 45.1%, p<0.001); females experienced more violence than males from a romantic partner (33.3% vs. 5.0%, p<0.001), parent/caregiver (32.4% vs. 17.6%, p = 0.02), and stranger (19.7% vs. 5.2%, p<0.001). CONCLUSION: The widespread and overlapping prevalence of multiple types of violence highlights the critical need for prevention and response efforts that are tailored to youths' sex and the perpetrator type. Future research should explore violence victimization and HIV outcomes, and the measurement of psychological abuse and sexual violence, among HIV-positive AYA in the region.

Correction: Project YES! Youth Engaging for Success: A randomized controlled trial assessing the impact of a clinic-based peer mentoring program on viral suppression, adherence and internalized stigma among HIV-positive youth (15-24 years) in Ndola, Zambia.

Project YES! Youth Engaging for Success: A randomized controlled trial assessing the impact of a clinic-based peer mentoring program on viral suppression, adherence and internalized stigma among HIV-positive youth (15-24 years) in Ndola, Zambia.

BACKGROUND: Youth-led strategies remain untested in clinic-based programs to improve viral suppression (VS) and reduce stigma among HIV-positive adolescents and young adults (AYA) in sub-Saharan Africa. In response, Project YES! placed paid HIV-positive youth peer mentors (YPM) in four HIV clinics in Ndola, Zambia including a Children's Hospital (pediatric setting), an adult Hospital and two primary care facilities (adult settings). METHODS: A randomized controlled trial was conducted from December 2017 to February 2019. Consecutively recruited 15 to 24-year-olds were randomly assigned to an intervention arm with monthly YPM one-on-one and group sessions and optional caregiver support groups, or a usual care comparison arm. Survey data and blood samples were collected at baseline and at the six-month midline. Generalized estimating equation models evaluated the effect of study arm over time on VS, antiretroviral treatment (ART) adherence gap, and internalized stigma. RESULTS: Out of 276 randomized youth, 273 were included in the analysis (Intervention n = 137, Comparison n = 136). VS significantly improved in both arms (I:63.5% to 73.0%; C:63.7% to 71.3.0%) [OR:1.49, 95% CI:1.08, 2.07]. In a stratified analysis intervention (I:37.5% to 70.5%) versus the comparison (C:60.3% to 59.4%) participants from the pediatric clinic experienced a relative increase in the odds of VS by a factor of 4.7 [interaction term OR:4.66, 95% CI:1.84, 11.78]. There was no evidence of a study arm difference in VS among AYA in adult clinics, or in ART adherence gaps across clinics. Internalized stigma significantly reduced by a factor of 0.39 [interaction term OR:0.39, 95% CI:0.21,0.73] in the intervention (50.4% to 25.4%) relative to the comparison arm (45.2% to 39.7%). CONCLUSIONS: Project YES! engaged AYA, improving VS in the pediatric clinic and internalized stigma in the pediatric and adult clinics. Further research is needed to understand the intersection of VS and internalized stigma among AYA attending adult HIV clinics. TRIAL REGISTRATION: ClinicalTrials.gov NCT04115813.

Intimate partner violence polyvictimisation and HIV among coupled women in Zambia: Analysis of a population-based survey.

Women in sub-Saharan Africa are disproportionately at risk for the dual epidemics of intimate partner violence (IPV) and HIV. Little is known about how specific violence profiles affect women's HIV risk, limiting effective intervention. We analysed couples' data from the Zambia Demographic and Health Survey 2013-2014 to evaluate relationships among IPV, male partner HIV status and women's HIV status. We considered the individual and combined effects of physical, sexual, emotional, and high controlling behaviour violence and accumulated violence exposure, respectively. Among partnered women, 48.9% (n = 2,812) experienced IPV victimisation, of whom 52.1% (n = 1,465) reported polyvictimisation (experiencing two or more violence types). Female HIV prevalence was 13.2%. Adjusted for demographics, HIV was significantly higher for women who experienced three (17.3%, aPR 1.33, 95%CI: 1.04-1.69, p = 0.02) or four (22.1%, aPR 1.66, 95%CI: 1.23-2.26, p ≤ 0.01) types versus no IPV. Violence including emotional and/or high controlling victimisation was associated with female HIV infection (aPR: 1.31, 95%CI: 1.09-1.57, p = 0.01). Physical and/or sexual violence victimisation in the absence of other victimisation was not associated with HIV (aPR: 0.92, 95%CI:0.73-1.15, p = 0.46). IPV and HIV interventions are incomplete without addressing emotional and controlling IPV and the role of coercive relationship dynamics in transmission risk.

Violence against children in Latin America and the Caribbean: What do available data reveal about prevalence and perpetrators?

OBJECTIVE: To describe the prevalence of recent physical, sexual, and emotional violence against children 0 - 19 years of age in Latin America and the Caribbean (LAC) by age, sex, and perpetrator. METHODS: A systematic review and analysis of published literature and large international datasets was conducted. Eligible sources from first record to December 2015 contained age-, sex-, and perpetrator-specific data from LAC. Random effects meta-regressions were performed, adjusting for relevant quality covariates and differences in violence definitions. RESULTS: Seventy-two surveys (2 publications and 70 datasets) met inclusion criteria, representing 1 449 estimates from 34 countries. Prevalence of physical and emotional violence by caregivers ranged from 30% - 60%, and decreased with increasing age. Prevalence of physical violence by students (17% - 61%) declined with age, while emotional violence remained constant (60% - 92%). Prevalence of physical intimate partner violence (IPV) ranged from 13% - 18% for girls aged 15 - 19 years. Few or no eligible past-year estimates were available for any violence against children less than 9 years and boys 16 - 19 years of age; sexual violence against boys (any age) and girls (under 15 years); IPV except for girls aged 15 - 19 years; and violence by authority figures (e.g., teachers) or via gangs/organized crime. CONCLUSION: Past-year physical and emotional violence by caregivers and students is widespread in LAC across all ages in childhood, as is IPV against girls aged 15 - 19 years. Data collection must be expanded in LAC to monitor progress towards the sustainable development goals, develop effective prevention and response strategies, and shed light on violence relating to organized crime/gangs.

[RESUMEN]. Objetivo. Describir la prevalencia de la violencia física, sexual y emocional infligida recientemente en niños y niñas de 0 a 19 años en América Latina y el Caribe (ALC) según la edad, el sexo y el agresor. Métodos. Se llevó a cabo una revisión y un análisis sistemáticos de la bibliografía publicada en los grandes conjuntos de datos. Las fuentes desde los primeros registros hasta diciembre del 2015 que cumplían los criterios fueron las que contenían datos específicos de América Latina y el Caribe en función de la edad, el sexo y el agresor. Se realizaron metarregresiones de los efectos aleatorios, con ajustes pertinentes para las covariables de calidad y las diferencias en las definiciones de violencia. Resultados. Setenta y dos encuestas (2 publicaciones y 70 conjuntos de datos) cumplieron los criterios de inclusión, que representaban 1.449 estimaciones de 34 países. La prevalencia de la violencia física y emocional infligida por cuidadores fue del 30% al 60% y disminuyó al aumentar la edad. La prevalencia de la violencia física infligida por estudiantes (17% a 61%) disminuyó con la edad, mientras que la violencia emocional se mantuvo constante (60% a 92%). La prevalencia de la violencia física infligida por la pareja fue de 13% a 18% para las niñas en edades de 15 a 19 años. Fueron pocas o inexistentes las estimaciones que cumplieran los criterios realizadas el año pasado sobre: la violencia de todo tipo contra los niños y las niñas menores de 9 años y los niños entre los 16 y 19 años; la violencia sexual contra los niños de cualquier edad y las niñas menores de 15 años; la violencia infligida por la pareja, salvo en niñas de 15 a 19 años; y la violencia infligida por figuras de autoridad (por ejemplo profesores) o por pandillas o el crimen organizado. Conclusión. La violencia emocional y física infligida por los cuidadores y estudiantes es generalizada en América Latina y el Caribe en todas las edades en la niñez, al igual que la violencia infligida por la pareja hacia niñas en edades entre los 15 y 19 años. Se debe ampliar la recopilación de datos en América Latina y el Caribe para dar seguimiento al progreso hacia los objetivos de desarrollo sostenible, elaborar estrategias eficaces de prevención y respuesta, y arrojar luz sobre la violencia en relación con el crimen organizado y las pandillas.

[RESUMO]. anos de idade na América Latina e no Caribe (ALC), discriminada por idade, sexo e autor da agressão. Métodos. Foi realizada uma revisão sistemática e análise da literatura publicada e de grandes conjuntos de dados internacionais. As fontes qualificadas do primeiro registro de dezembro de 2015 continham dados provenientes da ALC, discriminados por idade, sexo e autor da agressão. Foi usada a técnica de metarregressão de efeitos aleatórios, com ajuste para covariáveis de interesse de qualidade e para diferenças nas definições de violência. Resultados. Setenta e dois levantamentos (2 publicações e 70 conjuntos de dados) satisfizeram os critérios de inclusão, representando 1.449 estimativas provenientes de 34 países. A prevalência da violência física e emocional por cuidadores variou de 30% a 60%, sendo que este percentual diminuiu com o aumento da idade. A prevalência da violência física escolar (17% a 61%) diminuiu com a idade e a prevalência da violência infantil emocional ficou constante (60% a 92%). A prevalência da violência física por parceiro íntimo variou de 13% a 18% nas adolescentes entre 15 e 19 anos de idade. Foram encontradas poucas estimativas para o ano precedente, ou as estimativas existentes não satisfizeram os critérios, quanto à violência infantil em crianças menores de 9 anos e adolescentes do sexo masculino entre 16 e 19 anos de idade, à violência sexual contra meninos (em qualquer idade) e meninas (menores de 15 anos), à violência por parceiro íntimo, exceto em meninas entre 15 e 19 anos de idade e à violência infligida por figuras de autoridade (como professores) ou gangues/crime organizado. Conclusão. A violência física e emocional no ano precedente praticada por cuidadores e na escola é generalizada na ALC e ocorre em todas as faixas etárias na infância, assim como a violência por parceiro íntimo contra as adolescentes entre 15 e 19 anos de idade. A coleta de dados deve ser ampliada na ALC para monitorar o progresso rumo ao alcance dos objetivos de desenvolvimento sustentável, criar estratégias efetivas de prevenção e resposta à violência e identificar a violência relativa ao crime organizado/quadrilhas.
