Social Marketing Perspective on Participant Recruitment in Informatics-Based Intervention Studies.

Effective recruitment strategies are pivotal for informatics-based intervention trials success, particularly for people living with HIV (PLWH), where engagement can be challenging. Although informatics interventions are recognized for improving health outcomes, the effectiveness of their recruitment strategies remains unclear. We investigated the application of a social marketing framework in navigating the nuances of recruitment for informatics-based intervention trials for PLWH by examining participant experiences and perceptions. We used qualitative descriptive methodology to conduct semi-structured interviews with 90 research participants from four informatics-based intervention trials. Directed inductive and deductive content analyses were guided by Howcutt et al.'s social marketing framework on applying the decision-making process to research recruitment. The majority were male (86.7%), living in the Northeast United States (56%), and identified as Black (32%) or White (32%). Most participants (60%) completed the interview remotely. Sixteen subthemes emerged from five themes: motivation, perception, attitude formation, integration, and learning. Findings from our interview data suggest that concepts from Howcutt et al.'s framework informed participants' decisions to participate in an informatics-based intervention trial. We found that the participants' perceptions of trust in the research process were integral to the participants across the four trials. However, the recruitment approach and communication medium preferences varied between older and younger age groups. Social marketing framework can provide insight into improving the research recruitment process. Future work should delve into the complex interplay between the type of informatics-based interventions, trust in the research process, and communication preferences, and how these factors collectively influence participants' willingness to engage.

Neighborhood-level characteristics as effect modifiers on the efficacy of the MyPEEPS mobile intervention in same-sex attracted adolescent men.

To estimate the effect of neighborhood-level modification on the efficacy of the MyPEEPS Mobile intervention on the reduction of condomless anal sex acts among same-sex attracted adolescent men. A series of generalized linear mixed model was used to examine if the effect of the MyPEEPS Mobile intervention on condomless anal sex acts was moderated by neighborhood-level factors using data from the 2019 American Community Survey US Census Bureau. "The magnitudes of intervention were significantly smaller at both 6- and 9-month follow-up among adolescents living in neighborhood with high proportions of Hispanic or Latino residents (IRR6M = 1.02, 95 % CI: 1.01, 1.02; IRR9M = 1.03, 95 % CI: 1.01, 1.05) and high proportions of families with income below the poverty level (IRR6M = 1.07, 95 % CI: 1.01, 1.12; IRR9M = 1.05, 95 % CI: 1.01, 1.10), which indicated that living in communities with a higher concentration of residents living under poverty or of Hispanic/and Latino ethnicity significantly modified the effective of program intervention on condomless sex among adolescent MSM. Understanding how neighborhood characteristics modify the effect of HIV prevention interventions may be useful in better targeting delivery and tailoring content of interventions based on neighborhood level characteristics such as the ones identified in this study.

Laboratory Changes During Gender-Affirming Hormone Therapy in Transgender Adolescents.

OBJECTIVES: Guidelines for monitoring of medications frequently used in the gender-affirming care of transgender and gender-diverse (TGD) adolescents are based on studies in adults or other medical conditions. In this study, we aimed to investigate commonly screened laboratory measurements in TGD adolescents receiving gender-affirming hormone therapy (GAHT). METHODS: TGD adolescents were recruited from 4 study sites in the United States before beginning GAHT. Hemoglobin, hematocrit, hemoglobin A1c, alanine transaminase, aspartate aminotransferase, prolactin, and potassium were abstracted from the medical record at baseline and at 6, 12, and 24 months after starting GAHT. RESULTS: Two-hundred and ninety-three participants (68% designated female at birth) with no previous history of gonadotropin-releasing hormone analog use were included in the analysis. Hemoglobin and hematocrit decreased in adolescents prescribed estradiol (-1.4 mg/dL and -3.6%, respectively) and increased in adolescents prescribed testosterone (+1.0 mg/dL and +3.9%) by 6 months after GAHT initiation. Thirteen (6.5%) participants prescribed testosterone had hematocrit > 50% during GAHT. There were no differences in hemoglobin A1c, alanine transaminase, or aspartate aminotransferase. There was a small increase in prolactin after 6 months of estradiol therapy in transfeminine adolescents. Hyperkalemia in transfeminine adolescents taking spironolactone was infrequent and transient if present. CONCLUSIONS: Abnormal laboratory results are rare in TGD adolescents prescribed GAHT and, if present, occur within 6 months of GAHT initiation. Future guidelines may not require routine screening of these laboratory parameters beyond 6 months of GAHT in otherwise healthy TGD adolescents.

Assessing Preferences for Long-Acting Injectable Pre-Exposure Prophylaxis Among Young Adult Sexual Minority Men and Transgender Women.

OBJECTIVE: Oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV transmission. However, oral PrEP uptake is low, particularly among sexual and gender minority youth who are vulnerable to HIV infection. Alternative methods of PrEP delivery, such as long-acting injectable (LAI) PrEP may overcome barriers and be preferred. However, attitudes and preferences of younger sexual and gender minorities towards LAI PrEP have not been well studied. The purpose of this study is to describe preferences for initiating LAI PrEP among sexual and gender minority youth. METHODS: We analyzed data collected as part of an HIV prevention randomized trial from January 2022 to February 2023, using multiple regression to identify factors associated with a preference for LAI PrEP. RESULTS: The study sample (N = 265) was 50% youth of color, mean age 25 years (SD=3.4, range=18-31), and primarily identified as gay (71%) and male (91%). Forty two percent had heard of LAI PrEP and 31% preferred LAI PrEP over other prevention methods. In multiple regression analysis, LAI PrEP preference was associated with identifying as White, previous PrEP experience, and perceived LAI PrEP efficacy. CONCLUSIONS: We conclude that gaps in awareness exist for LAI PrEP, however it may be preferred over other prevention methods especially in White youth, those with PrEP experience and higher perceptions of its efficacy. More education and outreach are needed to prevent extension of existing race and ethnicity disparities in use of oral daily PrEP to LAI PrEP.

Social/Sexual Networks of People Newly Diagnosed with HIV in Ibadan, Nigeria.

Young men who have sex with men (YMSM) in Nigeria are ten times more likely to be living with HIV-1 than other young men. Due to stigma and criminalization of same-sex sexual behavior, YMSM sexual networks are likely to overlap with those of the general population, leading to a generalized HIV-1 epidemic. Due to limited research on social/sexual network dynamics related to HIV-1 in Nigeria, our study focused on YMSM and sought to assess the feasibility and acceptability of collecting social and sexual network data in Network Canvas from individuals newly diagnosed with HIV-1 in Ibadan, Nigeria. The Network Canvas software was piloted at three sites in Ibadan, Nigeria to collect social/sexual network data from 151 individuals newly diagnosed with HIV-1. Our study sample included 37.7% YMSM; participants reported a mean of 2.6 social alters and 2.6 sexual alters. From the 151 egos and 634 alters, 85 potential unique individuals (194 total) were identified; 65 egos/alters were collapsed into 25 unique individuals. Our success collecting network data from individuals newly diagnosed with HIV-1 in Ibadan demonstrates clear feasibility and acceptability of the approach and the use of Network Canvas to capture and manage these data.

Successful Implementation Strategies in iCARE Nigeria-A Pilot Intervention with Text Message Reminders and Peer Navigation for Youth Living with HIV.

To address poor outcomes among adolescents and young adults living with HIV (AYA-HIV), iCARE Nigeria successfully piloted two-way text message antiretroviral therapy (ART) reminders together with peer navigation. Study participants had significant improvement in ART adherence and viral suppression at 48 weeks. Understanding facto of this intervention. We used explanatory, mixed methods to assess implementation outcomes (feasibility, acceptability, and adoption) and identify implementation strategies used or adapted to promote intervention success. Quantitative data included participant surveys, program records, and back-end mHealth data, and were summarized using descriptive statistics. Qualitative data were collected from key informants and focus group discussions with program staff and summarized using directed content analysis. iCARE Nigeria was feasible as evidenced by ease of recruitment, high retention of patients and peer navigators (PN), and successful deployment of initial text message reminders (99.9%). Most participants (95%) and PN (90%) found text message reminders were not bothersome or intrusive. Implementation strategies employed to facilitate intervention success included: (1) selecting, training, supervising, and matching of PN to patients; (2) tailoring frequency (daily to weekly) and mode of communication between PN and patients according to patient need; (3) routine screening for adherence challenges; (4) changing phone airtime stipends from monthly to weekly in response to rapid depletion; and (5) conducting telecommunication needs assessments, to identify and troubleshoot implementation barriers (issues with mobile devices, power availability). iCARE Nigeria was feasible and acceptable with high adoption by stakeholders. The implementation strategies identified here can be tailored for intervention scale-up in similar environments to promote ART adherence for AYA-HIV.

Mixed methods implementation research to understand success of intensive combination approach to roll back the epidemic in Nigerian adolescents) (iCARE Nigeria) HIV testing uptake and linkage to care among young men focusing on young men who have sex with men in Ibadan.

BACKGROUND: HIV seroprevalence in Nigeria is increasing among men who have sex with men (MSM) from 14% to 2007 to 23% in 2014, threatening progress towards ending the epidemic in the country. Expanding access to HIV testing and linkage to care for key populations, like young MSM (YMSM), is critical to end the HIV epidemic in Nigeria. The Intensive Combination Approach to Roll Back the Epidemic in Nigerian Adolescents (iCARE Nigeria) pilot intervention successfully implemented a combination of evidence-based interventions utilizing peer navigators and popular social media apps and platforms to reach young men at risk for HIV exposure, including YMSM. We conducted sequential mixed methods explanatory implementation research to expand on the previously reported effectiveness and implementation outcomes and to explore the determinants and strategies which contributed to primary study results. METHODS: We conducted key informant interviews and focus group discussions with 2 peer navigators and 3 study staff at the end of the pilot. We used directed content analysis to understand the quantitative results from the pilot. Using the Implementation Research Logic Model, we were able to identify and map strategies through mechanisms of action from barriers addressed to the reported implementation outcomes including feasibility, acceptability fidelity and adoption. RESULTS: We found that iCARE Nigeria's pilot intervention implementers reported high feasibility, acceptability fidelity and adoption were associated with implementation of strategies which addressed many challenging contextual factors, including social stigma, online social networking, legal barriers surrounding MSM behavior, and the COVID-19 pandemic. These strategies included integration of stakeholders' interests, selection of experienced peer navigators including from the targeted population, training and supportive supervision using an implementation guide, ensuring safety (COVID and legal) and identification of clinics serving the targeted population. CONCLUSION: Mixed methods using implementation research frameworks provided insights into the strategies and barriers and facilitators they addressed which may explain the success of the pilot. These results can inform strategies needed to scale-up the intervention to youth including YMSM in other areas in Nigeria and the region.

Mental Health and Gender Affirmation of Black and Latine Transgender/Nonbinary Youth Compared to White Peers Prior to Hormone Initiation.

PURPOSE: To compare baseline mental health symptoms and gender affirmation between Black/Latine versus White transgender/nonbinary youth (BLTY vs. WTY) and examine relationships between gender affirmation and mental health symptoms, and whether associations differed by race/ethnicity subgroup. METHODS: Baseline data were analyzed from the gender-affirming hormone cohort of the Trans Youth Care United States Study-a 4-clinic site, observational study. Mental health symptoms assessed included depression, suicidality, and anxiety. Gender affirmation measures included the parental acceptance subscale from the perceived Parental Attitudes of Gender Expansiveness Scale-Youth Report; non-affirmation, internalized transphobia, and community connectedness subscales from the Gender Minority Stress and Resilience Measure-Adolescent; and self-reported living full time in affirmed gender. Fisher exact tests and independent sample t tests compared mental health symptoms and gender affirmation between subgroups. Logistic regression analyses evaluated associations between gender affirmation and mental health symptoms. Interaction analyses assessed differences in associations between subgroups. RESULTS: The sample (mean age 16 years, range 12-20 years) included 92 BLTY (35%) and 170 WTY (65%). Subgroups had comparable prevalence of depression and anxiety symptoms. WTY had higher prevalence of lifetime suicidality (73% vs. 59%; p = .02). There were no differences in gender affirmation. Among the whole sample, higher parental acceptance decreased odds of depression symptoms. Not living in affirmed gender increased odds of depression symptoms. Higher non-affirmation and internalized transphobia increased odds of depression and anxiety symptoms and suicidality. Associations did not vary by subgroup. DISCUSSION: BLTY and WTY had comparable mental health symptoms. For both subgroups, gender affirmation decreased odds of those symptoms.

A randomized stepped wedge trial of an intensive combination approach to roll back the HIV epidemic in Nigerian adolescents: iCARE Nigeria treatment support protocol.

BACKGROUND: Nigeria is one of six countries with half the global burden of youth living with HIV. Interventions to date have been inadequate as AIDS-related deaths in Nigeria's youth have remained unchanged in recent years. The iCARE Nigeria HIV treatment support intervention, a combination of peer navigation and SMS text message medication reminders to promote viral suppression, demonstrated initial efficacy and feasibility in a pilot trial among youth living with HIV in Nigeria. This paper describes the study protocol for the large-scale trial of the intervention. METHODS: The iCARE Nigeria-Treatment study is a randomized stepped wedge trial of a combination (peer navigation and text message reminder) intervention, delivered to youth over a period of 48 weeks to promote viral suppression. Youth receiving HIV treatment at six clinical sites in the North Central and South Western regions of Nigeria were recruited for participation. Eligibility criteria included registration as a patient at participating clinics, aged 15-24 years, on antiretroviral therapy for at least three months, ability to understand and read English, Hausa, Pidgin English, or Yoruba, and intent to remain a patient at the study site during the study period. The six clinic sites were divided into three clusters and randomized to a sequence of control and intervention periods for comparison. The primary outcome is plasma HIV-1 viral load suppression, defined as viral load ≤ 200 copies/mL, in the intervention period versus the control period at 48 weeks of intervention. DISCUSSION: Evidence-based interventions to promote viral load suppression among youth in Nigeria are needed. This study will determine efficacy of a combination intervention (peer navigation and text message reminder) and collect data on potential implementation barriers and facilitators to inform scale-up if efficacy is confirmed.

A Cross-sectional Study of Perceived Stress and Racial Discrimination Among a National Sample of Young Men Who Have Sex With Men.

ABSTRACT: Research regarding the impact of racism on stress among young men who have sex with men (YMSM) is sparse. Secondary data were assessed from a 2018-2020 national mHealth prevention trial for YMSM aged 13-18 years (N = 542). Linear regression models examined associations between perceived stress and interpersonal and vicarious racism, adjusting for covariates. Stratified models by race/ethnicity were included. A subanalysis (n = 288) examined associations between nine interpersonal racial discriminatory events and perceived stress. Over 50% of participants experienced racial discrimination. In the multivariable models, exposure to interpersonal (ß = 1.43, p-value: .038) and vicarious (ß = 1.77, p-value: .008) racism was associated with perceived stress because there were four interpersonal racial discriminatory events. Stratified analysis by race/ethnicity found significant associations between interpersonal and vicarious racism and perceived stress among some racial/ethnic groups. Racial discrimination was common among YMSM, making them susceptible to the possible effects of vicarious and interpersonal racism on stress.

High Internalized Transphobia and Low Gender Identity Pride Are Associated With Depression Symptoms Among Transgender and Gender-Diverse Youth.

PURPOSE: Prior studies have identified a significant relationship between internalized transphobia and poor mental health among transgender and gender-diverse (TGD) adults; however, this relationship has not been extensively examined among youth. Further, little research has sought to explore protective factors, such as identity pride, and their influence on this relationship. We examined the association between internalized transphobia and depression and anxiety symptoms among TGD youth and explored the moderating role of gender identity pride on these associations. METHODS: Participants were 315 TGD youth ages 12-20 years (mean = 16; standard deviation = 1.89) seeking gender-affirming hormone treatment at one of four major pediatric hospitals across the United States. At the time of enrollment, participants were naïve to gender-affirming hormone treatment. Participants self-reported mental health, internalized transphobia, and identity pride. Multiple regression models were used with depression and anxiety symptoms as outcomes and age, designated sex at birth, and perceived parental support included as covariates. RESULTS: Greater internalized transphobia was associated with greater depressive symptoms, and gender identity pride moderated this relationship, such that greater gender identity pride was associated with fewer depressive symptoms. Greater internalized transphobia was significantly associated with greater anxiety symptoms; no moderation effect was observed for this relationship. DISCUSSION: Gender identity pride influenced mental health symptoms for youth experiencing internalized transphobia and represents a potential key protective factor. These results support efforts to further develop, test, and implement clinical inventions to bolster identity pride for TGD youth.

A cross-sectional analysis of psychosocial and structural barriers and facilitators associated with PrEP use among a sample of transgender women in Chicago, IL.

BACKGROUND: Expanding pre-exposure prophylaxis (PrEP) among transgender women in the United States is an important strategy to meet national HIV prevention goals, however self-reported use of PrEP is low in this group. METHODS: This study reports the findings of a cross-sectional analysis of the relationship of barriers as well as facilitators to recent PrEP use among transgender women enrolled in an evaluation of the TransLife Care project (Chicago, Illinois), a structural intervention designed to meet basic needs. We computed multivariable prevalence ratios for barriers, facilitators and recent PrEP use, controlling for demographics. RESULTS: Findings suggest that psychosocial and structural barriers, including moderate/high alcohol use, stimulant use, and history of incarceration were all positively associated with recent PrEP use among urban transgender women. In addition, a psychosocial facilitator, gender affirmation, was positively associated with recent PrEP use, while, while collective self-esteem, a was negatively associated with it. Finally, common indications for PrEP have high sensitivity, but low specificity and predictive value for identifying those on PrEP. CONCLUSION: We conclude that despite a large gap in PrEP use among those with indications, individuals experiencing psychosocial and structural barriers are more likely to use PrEP, and facilitators, such as psychological sense of affirmed gender may support its use.

Findings From the Step Up, Test Up Study of an Electronic Screening and Brief Intervention for Alcohol Misuse in Adolescents and Young Adults Presenting for HIV Testing: Randomized Controlled Efficacy Trial.

BACKGROUND: Substance use, particularly binge drinking of alcohol and noninjection substance use, is associated with increased risk for HIV infection among youth, but structured substance use screening and brief intervention are not often provided as part of HIV risk reduction. OBJECTIVE: The purpose of the study was to test the efficacy of a fully automated electronic screening and brief intervention, called Step Up, Test Up, to reduce alcohol misuse among adolescents and young adults presenting for HIV testing. Secondary objectives were reduction in sexual risk and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention. METHODS: Youth aged 16 years to 25 years who presented for HIV testing at community-based locations were recruited for study participation. Those who screened at moderate to high risk on the Alcohol Use Disorders Identification Test were randomized (1:1) to either an electronic brief intervention or a time-attention control. The primary outcome was change in alcohol use at 1, 3, 6, and 12-month follow-ups. Negative binomial and log binomial regression analyses with generalized estimating equations were conducted to evaluate the intervention efficacy. RESULTS: Among a sample of 329 youth, there were no significant differences in alcohol use outcomes between conditions over time or at the 1, 3, 6, or 12-month time points. In terms of secondary outcomes, there was evidence of reduction in condomless insertive anal sex under the influence of alcohol and drugs at 12 months compared with 3 months in the intervention versus the attention control condition (incidence rate ratio=0.15, 95% CI 0.05-0.44); however, there were no other significant differences in sexual risk and no difference in PrEP engagement. CONCLUSIONS: We found no effect of electronic brief intervention to reduce alcohol use and some effect on sexual risk among youth aged 16 years to 25 years who present for HIV testing. TRIAL REGISTRATION: ClinicalTrials.gov number NCT02703116; https://clinicaltrials.gov/ct2/show/NCT02703116. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.1186/s12889-020-8154-6.

Psychosocial Functioning in Transgender Youth after 2 Years of Hormones.

BACKGROUND: Limited prospective outcome data exist regarding transgender and nonbinary youth receiving gender-affirming hormones (GAH; testosterone or estradiol). METHODS: We characterized the longitudinal course of psychosocial functioning during the 2 years after GAH initiation in a prospective cohort of transgender and nonbinary youth in the United States. Participants were enrolled in a four-site prospective, observational study of physical and psychosocial outcomes. Participants completed the Transgender Congruence Scale, the Beck Depression Inventory-II, the Revised Children's Manifest Anxiety Scale (Second Edition), and the Positive Affect and Life Satisfaction measures from the NIH (National Institutes of Health) Toolbox Emotion Battery at baseline and at 6, 12, 18, and 24 months after GAH initiation. We used latent growth curve modeling to examine individual trajectories of appearance congruence, depression, anxiety, positive affect, and life satisfaction over a period of 2 years. We also examined how initial levels of and rates of change in appearance congruence correlated with those of each psychosocial outcome. RESULTS: A total of 315 transgender and nonbinary participants 12 to 20 years of age (mean [±SD], 16±1.9) were enrolled in the study. A total of 190 participants (60.3%) were transmasculine (i.e., persons designated female at birth who identify along the masculine spectrum), 185 (58.7%) were non-Latinx or non-Latine White, and 25 (7.9%) had received previous pubertal suppression treatment. During the study period, appearance congruence, positive affect, and life satisfaction increased, and depression and anxiety symptoms decreased. Increases in appearance congruence were associated with concurrent increases in positive affect and life satisfaction and decreases in depression and anxiety symptoms. The most common adverse event was suicidal ideation (in 11 participants [3.5%]); death by suicide occurred in 2 participants. CONCLUSIONS: In this 2-year study involving transgender and nonbinary youth, GAH improved appearance congruence and psychosocial functioning.

A feasibility study of the use of HIV self-tests in young men who have sex with men.

Studies on HIV self-testing (HIV-ST) have been limited to adults (age 18+). The study assessed use of HIV-ST among a diverse group of young men who have sex with men (YMSM) in the United States (US) and assessed differences in uptake by demographic characteristics and requirements for parental consent. This study demonstrated feasibility of HIV-ST for YMSM as young as 14 years of age, which suggests potential for increasing HIV testing in this young age group and promoting health equity.

Physical Inactivity and the Role of Bullying Among Gender Minority Youth Participating in the 2017 and 2019 Youth Risk Behavior Survey.

PURPOSE: Evidence from small-scale studies suggests that transgender youth are less physically active than nontransgender youth, putting them at risk for worse health outcomes. This study examined the relationship between gender modality and participation in physical activity, physical education (PE), and sports teams in a multistate sample of high school youth and assessed whether bullying impacted this relationship. METHODS: Multiple regression was used to analyze data from the state and local Youth Risk Behavior Survey from 2017 to 2019 to examine the relationship between the gender modality and participation in physical activity, PE, and sports teams. The sample was stratified by sex and adjusted for demographics and in-school and online bullying victimization. RESULTS: Transgender participants who reported a male or female sex, respectively, reported lower odds of physical activity (adjusted odds ratio [aOR] 0.46, p < .001; aOR 0.46, p < .001, respectively) but similar odds of PE participation. Female transgender students were less likely to participate in sports (aOR 0.55, p = .007); however, this relationship was not seen in adjusted models. Adjusting for demographics, male transgender students were significantly more likely to participate in sports (aOR 2.1, p = .002). Adjusting for bullying experiences did not significantly change these results. DISCUSSION: Transgender youth are less likely to participate in physical activity but participate similarly or more than cisgender peers in PE and sports. Factors other than bullying may limit physical activity among transgender youth, and the Youth Risk Behavior Survey may not capture experiences of trans-specific victimization. Increased inclusion and safety may help increase physical activity and amplify its benefits for transgender students.

Systematic Review of mHealth Interventions for Adolescent and Young Adult HIV Prevention and the Adolescent HIV Continuum of Care in Low to Middle Income Countries.

Adolescents and young adults (AYA) in low to middle income countries (LMIC) have poorer outcomes along each step in the HIV continuum of prevention and care compared to younger children or older adults. The use of mHealth technology provides a potentially promising implementation strategy for interventions to remedy these disparities. We therefore conducted a systematic review of the English literature and conference proceedings from January 1, 2000 to April 1, 2021 evaluating mHealth interventions targeting AYA along each step of the HIV continuum of care in LMIC. We identified 27 mHealth interventions across the HIV continuum, with no interventions addressing transition from pediatric to adult care. The majority of studies were single arm, uncontrolled or underpowered, with few randomized trials resulting in mixed and inconclusive outcomes. mHealth interventions have potential to remedy disparities along the HIV continuum of care for AYA in LMIC but larger, powered randomized trials are needed.

RESUMEN: Los adolescentes y adultos jóvenes (AYA) en países de ingresos bajos a medianos (LMIC) tienen peores resultados en cada paso del continuo de prevención y atención del VIH en comparación con los niños más pequeños o los adultos mayores. El uso de la tecnología mHealth proporciona una estrategia de implementación potencialmente prometedora para las intervenciones para remediar estas disparidades. Por lo tanto, realizamos una revisión sistemática de los resúmenes y artículos publicados en inglés desde el 1 de enero de 2000 hasta el 1 de abril de 2021 para evaluar las intervenciones de mHealth dirigidas a AYA a lo largo de cada paso del continuo de atención del VIH en LMIC. Identificamos 27 intervenciones de mHealth en todo el continuo del VIH, sin intervenciones que abordaran la transición de la atención pediátrica a la de adultos. La mayoría de los estudios fueron de un solo brazo, no controlados o con bajo poder estadístico, con pocos ensayos aleatorios que dieron resultados mixtos y no concluyentes. Las intervenciones de mHealth tienen el potencial de remediar las disparidades a lo largo de la continuidad de la atención del VIH para AYA en LMIC, pero se necesitan ensayos aleatorios más grandes y potentes.

Using the Implementation Research Logic Model as a Lens to View Experiences of Implementing HIV Prevention and Care Interventions with Adolescent Sexual Minority Men-A Global Perspective.

Adolescents and sexual minority men (SMM) are high priority groups in the United Nations' 2021 - 2016 goals for HIV prevention and viral load suppression. Interventions aimed at optimizing HIV prevention, testing and viral load suppression for adolescents must also attend to the intersectional realities influencing key sub-populations of SMM. Consequently, there is not a robust evidence-base to guide researchers and program partners on optimal approaches to implementing interventions with adolescent SMM. Using a multiple case study design, we integrated the Implementation Research Logic Model with components of the Consolidated Framework for Implementation Research and applied it as a framework for a comparative description of ten HIV related interventions implemented across five countries (Ghana, Kenya, Nigeria, Tanzania and United States). Using self-reported qualitative survey data of project principal investigators, we identified 17 of the most influential implementation determinants as well as a range of 17 strategies that were used in 90 instances to support intervention implementation. We highlight lessons learned in the implementation research process and provide recommendations for researchers considering future HIV implementation science studies with adolescent SMM.
