RESUMO
BACKGROUND: Emerging adults (aged 18-29) are less likely to receive the COVID-19 vaccine than any other adult age group. Black Americans are less likely than non-Hispanic white Americans to be fully vaccinated against COVID-19. This study explored factors which affect vaccine intention and attitudes in Black American emerging adults with asthma. METHODS: Participants were recruited from an NHLBI-funded clinical trial to improve asthma control. Fifty-nine Black American emerging adults completed a Qualtrics survey that assessed asthma control, intention to vaccinate, and factors which may affect the decision to vaccinate. Twenty-five participants also completed a semi-structured interview via Zoom. Bivariate correlations and descriptive statistics, including Chi Square analyses, were run using SPSS. Interview thematic analyses were conducted via QDA Miner. RESULTS: Of the 59 Black American emerging adults with asthma who completed surveys, 32.2% responded that they were highly unlikely to receive the COVID-19 vaccine, while 50.8% responded that they were highly likely to receive it. Increased asthma control was significantly correlated with a higher likelihood to discuss the COVID-19 vaccine with their healthcare provider (ρ = 0.339, α = 0.011). Concerns about immediate (ρ= -0.261, α = 0.050) and long-term (ρ= -0.280, α = 0.035) side effects were inversely correlated with intention to vaccinate. Only 17% of the participants who were unemployed stated that they were highly likely to receive the vaccines compared to 65% of the participants who were employed; however, interview participants who were unemployed stated not needing the vaccine because they were protecting themselves by social distancing. When deciding whether to receive the vaccine, safety, efficacy, and immediate side effects were the top three factors for 91%, 54%, and 49% of the participants, respectively. Beliefs about the vaccines' safety and efficacy, information gathering, personal factors, and societal factors emerged as important themes from the interviews. CONCLUSION: Only half of the surveyed Black American emerging adults with asthma were highly likely to receive the COVID-19 vaccine. Safety and efficacy were important for the majority of the participants, regardless of vaccine intention. Greater asthma control, but not access to asthma-related healthcare, was correlated with intention to discuss the vaccine with their healthcare provider.

BACKGROUND: Anxiety and depression are mental health disorders that are often comorbid with asthma. Urban African American young adults with asthma often experience increased risk of anxiety and depression. OBJECTIVE: To explore relationships between symptoms of psychological distress and asthma-related anxiety with asthma outcomes among urban African American young adults with poorly controlled persistent asthma. METHODS: A secondary analysis of baseline data from a larger study of 141 African American young adults with uncontrolled persistent asthma was examined. Participants completed the Brief Symptom Inventory (BSI-18), Youth Asthma-related Anxiety Scale, Asthma Control Test (ACT), a daily diary to assess asthma symptoms; and number of asthma attacks. Spirometry assessed airway obstruction. Generalized linear models tested associations. RESULTS: In multivariable models testing, higher somatization scores were significantly associated with lower ACT scores (adjusted ß = -0.49; 95% CI = -0.69, -0.28; p < 0.01), and higher symptoms (adjusted ß = 0.39; 95% CI = 0.14, 0.65; p < 0.01). After adding asthma-related anxiety to the model, the somatization subscale and asthma-related anxiety were significantly associated with ACT scores (adjusted ß = -0.36; 95% CI = -0.57, -0.15; p < 0.01), (adjusted ß = -0.32; 95% CI = -0.50, -0.14; p < 0.01), respectively. Asthma-related anxiety was also significantly associated with asthma attacks (adjusted ß = 0.24; 95% CI = 0.05, 0.43; p < 0.05). CONCLUSION: This study suggests, asthma-related anxiety may differ from general anxiety and be related to poorly controlled asthma among African American young adults.

Considering the lack of validated stigma reduction interventions for youth living with HIV (YLWH), we evaluated effects of the Healthy Choices intervention on HIV-related stigma among YLWH. We analyzed data from the Adolescent Medicine Trials Network protocol 129, multi-site randomized controlled trial, applying latent growth curve modeling with two linear slopes estimating changes in Berger's Stigma Scale pre-intervention, 16, 28, and 52 weeks post-intervention, as well as the trajectory of stigma scores over the follow-up period (N = 183). Expected value for the growth intercept was statistically significant (Bintercept = 2.53; 95% CI 2.32, 2.73; p < 0.001), as were differences in the change from baseline to 16-week follow-up (Bintercept slope1 = - 0.02; 95% CI - 0.04, 0.01; p = 0.034). Expected value of the slope factor measuring growth over the follow-up period was non-significant suggesting that stigma scores were stable from 28 to 52 weeks. Our findings warrant replication and additional research comparing effects of this intervention to counterfactual controls.
RESUMEN: Teniendo en cuenta la falta de intervenciones validadas de reducción del estigma para los jóvenes que viven con el VIH (PVVS), evaluamos los efectos de la intervención Healthy Choices sobre el estigma entre los PVVS. Analizamos los datos del ensayo controlado aleatorio de múltiples sitios del protocolo 129 de Adolescent Medicine Trials Network, aplicando un modelo de curva de crecimiento latente con dos pendientes lineales que estiman los cambios de Berger's Stigma Scale antes de la intervención, ya a las 16, 28 y 52 semanas después de la intervención, así como la trayectoria de los niveles de estigma durante el período de seguimiento (N = 183). El valor esperado para el intercepto de crecimiento fue estadísticamente significativo (Bintercept = 2.53 IC del 95%: 2.32, 2.73 p < 0.001), así como las diferencias en el cambio desde el inicio hasta el seguimiento de 16 semanas (Bintercept slope 1 = -0.02 IC del 95% IC: -0.04, 0.01 p = 0.034). El valor esperado del factor que mide el crecimiento durante el período de seguimiento no fue significativo, sugiere que los niveles de estigma se mantuvieron estables de 28 a 52 semanas. Nuestros resultados justifican la replicación y la investigación adicional al comparar la intervención con comparativos.

Youth living with HIV (YLWH; aged 16-24) are at elevated risk of alcohol and drug use. Studies in older populations have identified patterns or profiles of multiple substance use differentially associated with mental health and anti-retroviral therapy (ART) adherence. No studies of YLWH have yet examined such patterns. A sample of 179 YLWH, reporting ART non-adherence and alcohol use, were recruited at five Adolescent Trials Network clinics in urban areas of the US between November 2014 and August 2017. Participants completed the Alcohol Smoking and Substance Involvement Screening Test (ASSIST) to assess substance use involvement scores, and the Brief Symptom Inventory. Latent Profile Analysis identified three substance use patterns: minimal illicit drug use (15.1%), cannabis only (56.4%), and global polysubstance use (28.5%). Global polysubstance users experienced more mental health problems compared to the minimal illicit drug use group. The co-occurrence of drug use with alcohol was common among these YLWH-all of whom reported ART adherence problems-indicating the importance of interventions capable of addressing multiple substance use rather than alcohol alone.

Objective: The goal of the current study was to determine how a set of social cognitive factors predict antiretroviral therapy (ART) medication adherence in youth living with HIV in an era of newer highly active ART medications using a conceptual model. Methods: Behaviorally infected youth living with HIV ages 13-24 (N = 822) from 14 sites within the Adolescent Medicine Trials Unit (AMTU) were included in the study. Structural equation modeling was used to explore predictors of ART medication adherence. Results: Results found that motivational readiness for ART was related to higher ART medication adherence, which was associated with lower viral load. Higher social support and higher self-efficacy had an indirect relationship with higher adherence through increased motivational readiness. Fewer psychological symptoms were associated with higher social support and higher self-efficacy. Lower substance use was directly associated with lower adherence. Conclusions: The results provide insight into factors that may be related to adherence in youth living with HIV. Findings suggest focusing on motivational readiness to increase adherence. Improving the patients' ART self-efficacy and strengthening their social support networks during treatment can increase motivational readiness for ART treatment. Furthermore, programs maybe more effective with the inclusion of risk reduction components especially those related to substance use.

OBJECTIVE: To test social cognitive predictors of medication adherence in racial/ethnic minority youth living with HIV using a conceptual model. METHODS: Youth were participants in two descriptive studies by the Adolescent Trials Network for HIV/AIDS Interventions. Minority youth ages 16-24 years who were prescribed antiretroviral medication were included (N = 956). Data were collected through chart extraction and/or laboratory testing and by Audio Computer-Assisted Self-Interview. RESULTS: 39% of youth reported suboptimal adherence. Path analysis was used to explore predictors of medication adherence. Higher self-efficacy predicted higher readiness and adherence. Greater social support predicted higher self-efficacy. Psychological symptoms and substance use were associated with several predictors and lower adherence. CONCLUSIONS: The model provided a plausible framework for understanding adherence in this population. Culturally competent, but individually tailored, interventions focused on increasing self-efficacy to take medication and reducing risk behaviors (e.g., substance use) may be helpful for racial or ethnic minority youth with HIV.

African American emerging adults (age 18-29 years) tend to have poor asthma outcomes, possibly due to poor adherence to medication. Few studies have explored barriers to controller adherence in this population. This study utilized electronic daily diaries to assess barriers to adherence and asthma symptoms among 141 African American emerging adults with uncontrolled persistent asthma and poor adherence. Participants reported symptoms M = 3.43 days (of 7 days). They reported unintentional (e.g., forgetting) and intentional (e.g., choosing not to take) barriers to adherence, but forgetting, being too busy, and sleeping through a dose were the most common. Significant correlations were found between symptoms and barriers, as well as asthma control and medication adherence in the expected directions. Asthma symptoms and number of barriers were significant predictors of asthma control. Existing intervention strategies such as text-messaging may prove effective to address these barriers, but measuring and addressing adherence remains complex.

HIV is now a chronic condition that can be managed. Adolescents and emerging adults represent a large proportion of new diagnoses, but struggle with many aspects of HIV-related self-management. Self-management of HIV is critical to maintaining health and involves retention in HIV care, medication adherence to achieve viral suppression, managing substance use, and sexual and general health-related behaviors. This article describes theoretic frameworks for HIV self-management as adapted for youth and reviews self-management interventions developed to improve health outcomes in youth living with HIV identified from a recent systematic review.

BACKGROUND: Vulnerable adolescents and emerging adults (aged 18-29 years), particularly young transgender women, are among the fastest-growing HIV positive populations worldwide. Thailand has the highest adult HIV seroprevalence in Asia, with a rate of infection among this population of 18%. Widespread technology offers opportunities for innovative mobile health (mHealth) interventions. Pre-exposure prophylaxis (PrEP) is an efficacious HIV prevention strategy recommended for at-risk individuals. PrEP is highly effective when taken as prescribed, but uptake and adherence have been low, with high discontinuation rates among youth. OBJECTIVE: We propose to develop and pilot a multi-component, technology-based intervention to promote PrEP usage. We will adapt an existing 2-session, technology-delivered, motivational interviewing-based intervention to focus on PrEP use in transgender women in Thailand. We call this the Motivational Enhancement System for PrEP Uptake and Adherence (MES-PrEP). We will also refine and enhance YaCool, a mobile app with integrated text messaging developed and used clinically by our Thai team. The new version of the app is called Enhanced YaCool, and it enables self-management of gender and sexual health (including PrEP). Our primary aim is to develop and assess the preliminary efficacy of this mHealth intervention. METHODS: We will utilize a multiphase optimization strategy (MOST) to identify the most effective intervention component or combination of components to improve PrEP usage in Thai transgender women. The study includes two phases: phase I (R21) includes qualitative interviews with key stakeholders to explore barriers and facilitators of PrEP usage through thematic analysis to inform intervention adaptation. Following this, we will adapt and beta-test MES-PrEP and Enhanced YaCool for functionality and feasibility using a community advisory board of HIV-negative Thai transgender women. In phase II (R33), we will conduct a MOST design-based trial to evaluate the feasibility, acceptability, and preliminary efficacy of MES-PrEP and Enhanced YaCool. Eighty HIV-negative participants who are currently taking PrEP and 80 participants who are not will be randomized to four conditions: (1) standard PrEP counseling (the control condition); (2) MES-PrEP and standard PrEP counseling; (3) Enhanced YaCool and standard PrEP counseling; and (4) MES-PrEP, Enhanced YaCool, and standard PrEP counseling. Feasibility and acceptability of the intervention will be assessed through usage patterns and the System Usability Scale. Preliminary impact will be assessed by evaluating the proportion of participants who initiate PrEP and their level of adherence to PrEP. Assessments will be at baseline and 1, 3, 6, 9, and 12 months postintervention. Biomarkers of adherence to PrEP, HIV, and other sexually transmitted infections will be collected. RESULTS: Upon project completion, we will have an optimized mHealth intervention to support the use of PrEP by transgender women that will be ready for testing in a larger efficacy trial. CONCLUSIONS: Even though transgender women in Thailand face increasing risks of HIV, few interventions have targeted them. Effective developmentally and culturally tailored interventions are needed to prevent HIV transmission in this high-risk population.

RESUMO
BACKGROUND: Adolescent asthma is highly prevalent and frequently uncontrolled despite control being achievable with good self-management. Anxiety, depression, and stress are associated with worse asthma outcomes, and may impact self-management; no previous review has examined this relationship. AIM: This scoping review assessed the nature of the current literature on mental health and asthma self-management among adolescents ages 11 to 24 and synthesized their relationships. METHODS: Guided by the PRISMA-ScR guidelines, we systematically searched the literature using MEDLINE, Embase, CINAHL, PsycInfo, and Scopus in September 2020 and updated it in June 2021. Included studies examined associations between anxiety, depression, and/or stress and asthma self-management in adolescents ages 11-24. We did not restrict study design, location, or date. RESULTS: Out of 1559 records identified, 14 met inclusion criteria. Types of self-management included trigger control, healthcare adherence, and overall symptom prevention and management. Anxiety symptoms were associated with poorer asthma self-management in four studies, but better in three. Depressive symptoms were associated with poorer asthma self-management in five studies, but better in two. Stress was associated with poorer self-management in one study. Mental health symptoms were nearly universally associated with poorer trigger control, but associations with healthcare adherence and overall symptom prevention and management varied. CONCLUSION: Mental health symptoms may facilitate or hinder asthma self-management depending on the types of mental health and self-management. Further research is needed to better understand this relationship and inform future interventions. Providers might assess mental health as a potential barrier to adolescent asthma self-management.

BACKGROUND: Asthma causes substantial morbidity and mortality in the United States, particularly among African American emerging adults (AAEAs; aged 18-30 years), but very few asthma programs have targeted this population. Interventions that provide education and address underlying motivation for managing asthma may be the most effective. However, intensive face-to-face interventions are often difficult to implement in this population. OBJECTIVE: The purpose of this study is to develop an effective mobile asthma management intervention to improve control among AAEAs. METHODS: We will assess the ability of multiple technologic components to assist and improve traditional asthma education. The first component is the Motivational Enhancement System for asthma management. It is a mobile 4-session intervention using supported self-regulation and motivational interviewing. Personalized content is based on each participant's activity level, daily experiences, and goals. The second component is supportive accountability. It is administered by asthma nurses using targeted mobile support (Skype/voice calls) to provide education, promote self-efficacy, and overcome barriers through a motivational interviewing-based framework. The third component is SMS text messaging. It provides reminders for asthma education, medication adherence, and physical activity. The fourth component is physical activity tracking. It uses wearable technology to help meet user-defined physical activity goals. Using a multiphase optimization strategy (MOST) framework, we will test intervention components and combinations of components to identify the most effective mobile intervention. The MOST framework is an innovative, and cost- and time-effective framework that uses engineering principles to produce effective behavioral interventions. We will conduct a component selection experiment using a factorial research design to build an intervention that has been optimized for maximum efficacy, using a clinically significant improvement in asthma. Participants (N=180) will be randomized to 1 of 6 intervention arms. Participants will be recruited from multiple sites of the American Lung Association-Airway Clinical Research Centers network and ambulatory care clinics at the Detroit Medical Center. Data collections will occur at baseline, and 3, 6, and 12 months. RESULTS: At study completion, we will have an empirically supported optimized mobile asthma management intervention to improve asthma control for AAEAs. We hypothesize that postintervention (3, 6, and 12 months), participants with uncontrolled asthma will show a clinically significant improvement in asthma control. We also hypothesize that improvements in asthma management behaviors (including physical activity), quality of life, symptoms, adherence, and exacerbation (secondary outcomes) will be observed. CONCLUSIONS: AAEAs are disproportionately impacted by asthma, but have been underrepresented in research. Mobile asthma management interventions may help improve asthma control and allow people to live healthier lives. During this project, we will use an innovative strategy to develop an optimized mobile asthma management intervention using the most effective combination of nurse-delivered asthma education, a smartphone app, and text messaging.

RESUMO
Importance: Youth living with HIV make up one-quarter of new infections and have high rates of risk behaviors but are significantly understudied. Effectiveness trials in real-world settings are needed to inform program delivery. Objective: To compare the effectiveness of the Healthy Choices intervention delivered in a home or community setting vs a medical clinic. Design, Setting, and Participants: This randomized clinical trial was conducted from November 1, 2014, to January 31, 2018, with 52 weeks of follow-up. Participants, recruited from 5 adolescent HIV clinics in the United States, were youths and young adults living with HIV aged 16 to 24 years who were fluent in English, were currently prescribed HIV medication, had a detectable viral load, and had used alcohol in the past 12 weeks. Individuals with an active psychosis that resulted in an inability to complete questionnaires were excluded. Data were analyzed from May to December, 2019. Interventions: Participants were randomized to receive the Healthy Choices intervention in either a home or clinic setting. Four 30-minute individual sessions based on motivational interviewing to improve (1) medication adherence and (2) drinking behavior were delivered during 10 weeks by trained community health workers. In session 1, participants chose which behavior to discuss first. Using motivational interviewing strategies, the community health worker elicited motivational language, guided the development of an individualized change plan while supporting autonomy, delivered feedback, and addressed knowledge gaps. Session 2 focused on the second target behavior. In subsequent sessions, community health workers reviewed the individualized change plan, monitored progress, guided problem solving, and helped maintain changes made. Main Outcomes and Measures: Primary outcomes were viral load and alcohol use change trajectories during 52 weeks of follow-up. Alcohol use severity and frequency were measured using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) (scores range from 0 to 33, with higher scores indicating greater severity of alcohol-related problems) and number of drinks consumed each day over a 30-day period, with timeline followback. Results: A total of 183 young people living with HIV (145 male [79.2%]; mean [SD] age, 21.4 [1.9] y) were randomized to the home setting (n = 90) or clinical setting (n = 93). Using growth-curve analysis, both groups showed declines in viral load after the intervention: among participants with available viral load information, in the home group, 12 participants (21%) had an undetectable viral load at 16 weeks, 12 (22%) at 28 weeks, and 10 (20%) at 52 weeks; in the clinic group, 16 participants (24%) had an undetectable viral load at 16 weeks, 20 (39%) at 28 weeks, and 18 (35%) at 52 weeks. However, the clinic group maintained gains, whereas those counseled at home had a significantly different and increasing trajectory during follow-up (unstandardized ß = -0.07; 95% CI,-0.14 to -0.01; P = .02). A similar pattern was observed in ASSIST scores during follow-up, with reduced ASSIST scores in the clinic group (unstandardized ß = -0.44; 95% CI,-0.81 to -0.07; P = .02). Conclusions and Relevance: In this trial, the Healthy Choices intervention resulted in improvements in viral load and alcohol use over 12 months. Unexpectedly, the clinic setting outperformed home-based delivery for viral suppression. Although cross-sectional differences in ASSIST scores were nonsignificant, clinic delivery did improve the trajectory of ASSIST scores during follow-up. Thus, clinics may be the more effective site for interventions aimed at viral load reduction for young people living with HIV. Trial Registration: ClinicalTrials.gov Identifier: NCT01969461.

BACKGROUND: Youth living with HIV (YLH) aged 13 to 24 years made up over a fifth (21%) of new HIV diagnoses in 2016, yet only 27% of YLH are virally suppressed. YLH have been shown to be poorly adherent to antiretroviral therapy (ART); however, there has been limited research investigating how to increase adherence in YLH. Mobile health (mHealth) interventions may be one promising way to do this. OBJECTIVE: This study (ATN [Adolescent Trials Network] 144 SMART) aimed to compare adaptive interventions that could increase ART adherence in YLH aged 15 to 24 years. This includes mHealth initiatives, the tapering of interventions, and the use of incentives. Cost-effectiveness of sequencing the interventions without incentives before providing incentives and the savings on societal costs due to suppressed viral loads will be determined. This protocol is part of the ATN Scale It Up program described in this issue by Naar et al. METHODS: This study uses a Sequential Multiple Assignment Randomized Trial design. Approximately 190 participants are being recruited, enrolled, and randomized to either cell phone support or text message support. Both intervention groups receive 3 months of intervention, followed by a second randomization based on response to the intervention. Responders test tapering their intervention, and nonresponders test receiving incentives. RESULTS: Data collection for this study is projected to begin in August 2018 and last until June 2020. CONCLUSIONS: This is an innovative study, particularly in terms of population, intervention types, focus on cost-effectiveness, and recruitment. This study could be particularly effective in improving adherence in YLH while reducing long-term individual and societal costs.

RESUMO
Reducing tobacco use among adolescents in China represents a significant challenge for global tobacco control. Existing behavioral theories developed in the West - such as the Protection Motivation Theory (PMT) - may be useful tools to help tackle this challenge. We examined the relationships between PMT factors and self-reported cigarette smoking behavior and intention among a random sample of vocational high school students (N=553) in Wuhan, China. Tobacco-related perceptions were assessed using the PMT Scale for Adolescent Smoking. Among the total sample, 45% had initiated cigarette smoking, and 25% smoked in the past month. Among those who never smoked, 15% indicated being likely or very likely to smoke in a year. Multiple regression modeling analysis indicated the significance of the seven PMT constructs, the four PMT perceptions and the two PMT pathways in predicting intention to smoke and actual smoking behavior. Overall, perceived rewards of smoking, especially intrinsic rewards, were consistently positively related to smoking intentions and behavior, and self-efficacy to avoid smoking was negatively related to smoking. The current study suggests the utility of PMT for further research examining adolescent smoking. PMT-based smoking prevention and clinical smoking cessation intervention programs should focus more on adolescents' perceived rewards from smoking and perceived efficacy of not smoking to reduce their intention to and actual use of tobacco.
