Changes in Internalized Stigma and HIV Health Outcomes in Individuals New to HIV Care: The Mediating Roles of Depression and Treatment Self-Efficacy

There is limited research on the effects of stigma on health outcomes among new-to-HIV care individuals. We examined the effect of changes in internalized stigma over time on health behaviors and outcomes such as viral suppression, antiretroviral therapy (ART) adherence, and visit adherence among new-to-HIV care individuals. We also analyzed the mediating effects of adherence self-efficacy and depressive symptoms in these associations. Participants were 186 persons living with HIV who initiated care at four HIV clinical sites in the United States and had diverse geographical and ethnic backgrounds. Baseline and 48-week follow-up assessments included measures of internalized stigma, ART adherence, depressive symptoms, and adherence self-efficacy. HIV visit adherence and viral load data were extracted from clinic records. Age, race, gender, insurance status, and site were controlled in all analyses. Logistic regression analyses were used to examine predictors of adherence and viral suppression. Change (decrease) in internalized stigma was calculated by subtracting follow-up internalized stigma scores from baseline scores and served as the main predictor. Mediation analyses included calculation of 95% confidence intervals for the indirect effects using bootstrapping. Decreases in internalized stigma over time were positively associated with viral suppression, ART adherence, and visit adherence. Adherence self-efficacy significantly mediated these effects of decrease in internalized stigma on all outcomes. Depressive symptoms only mediated the association between decrease in internalized stigma and ART adherence. Interventions that address internalized stigma and depressive symptoms, as well as adherence self-efficacy, may significantly improve adherence and viral suppression outcomes for individuals new to HIV care.

Resilience and HIV Treatment Outcomes Among Women Living with HIV in the United States: A Mixed-Methods Analysis

Resilience is defined as the ability and process to transform adversity into opportunities for growth and adaptation. Resilience may be especially important for people living with HIV (PLWH), who are susceptible to anxiety and depressive disorders, which are commonly linked to risk behaviors (i.e., alcohol and drug abuse), poor adherence to medical regimens, increased risk of morbidity and mortality, and related stigma and discrimination. To date, few studies have examined the impact of resilience on health-related behaviors and outcomes among PLWH, particularly among minority women living with HIV (WLWH) who are dealing with multiple stressors impacting their health. This study used a convergent parallel mixed-methods design to collect, analyze, and integrate qualitative and quantitative data from a subsample of WLWH enrolled in the Women's Interagency HIV Study (WIHS). The aims of the study were to (1) qualitatively examine the resilience perspectives of 76 marginalized WLWH, and; (2) quantitatively assess the associations of resilience with HIV health outcomes-adherence to antiretroviral therapy and viral suppression-in the context of differing levels of internalized HIV-related stigma and depressive symptoms (n = 420). Findings from this mixed-methods study suggest that resilience is an important resource that can aid WLWH in coping constructively with adversity by capitalizing on intrapersonal traits and states, interpersonal and institutional resources, and spiritual and/or religious practices. Given the complex medical and social needs of marginalized WLWH, intervention strategies should focus on mitigating psychosocial burdens of stigma and depression, in addition to building resilience.

Examining the Relationships Between Experienced and Anticipated Stigma in Health Care Settings, Patient-Provider Race Concordance, and Trust in Providers Among Women Living with HIV

Stigma in health care settings can have negative consequences on women living with HIV, such as increasing the likelihood of missed visits and reducing trust in their clinical providers. Informed by prior stigma research and considering knowledge gaps related to the effect of patient-provider race concordance, we conducted this study to assess if patient-provider race concordance moderates the expected association between HIV-related stigma in health care settings and patients' trust in their providers. Moderation analyses were conducted using Women's Interagency HIV Study data (N = 931). We found significant main effects for patient-provider race concordance. Higher experienced stigma was associated with lower trust in providers in all patient-provider race combinations [White-White: B = -0.89, standard error (SE) = 0.14, p = 0.000, 95% confidence interval, CI (-1.161 to -0.624); Black patient-White provider: B = -0.19, SE = 0.06, p = 0.003, 95% CI (-0.309 to -0.062); and Black-Black: B = -0.30, SE = 0.14, p = 0.037, 95% CI (-0.575 to -0.017)]. Higher anticipated stigma was also associated with lower trust in providers [White-White: B = -0.42, SE = 0.07, p = 0.000, 95% CI (-0.552 to -0.289); Black patient-White provider: B = -0.17, SE = 0.03, p = 0.000, 95% CI (-0.232 to -0.106); and Black-Black: B = -0.18, SE = 0.06, p = 0.002, 95% CI (-0.293 to -0.066)]. Significant interaction effects indicated that the negative associations between experienced and anticipated HIV-related stigma and trust in providers were stronger for the White-White combination compared with the others. Thus, we found that significant relationships between HIV-related experienced and anticipated stigma in health care settings and trust in providers exist and that these associations vary across different patient-provider race combinations. Given that reduced trust in providers is associated with antiretroviral medication nonadherence and higher rates of missed clinical visits, interventions to address HIV-related stigma in health care settings may improve continuum of care outcomes.

Resilience and Optimism as Moderators of the Negative Effects of Stigma on Women Living with HIV

Resilience and optimism may not only have main effects on health outcomes, but may also moderate and buffer negative effects of stressors. We examined whether dispositional resilience and optimism moderate the associations between HIV-related stigma in health care settings and health-related outcomes (trust in HIV health care providers and depression symptoms) among women living with HIV (WLHIV). One thousand four hundred five WLHIV in nine US cities completed validated questionnaires for cross-sectional analyses. Higher self-reported experienced and anticipated stigma and lower resilience and optimism were associated with higher depression symptoms and with lower trust in HIV providers. Importantly, resilience moderated the effects of experienced stigma (but not of anticipated stigma): When resilience was high, the association of experienced stigma with higher depression symptoms and lower trust in HIV providers was weaker compared with when resilience was low. Further, significant moderation effects suggested that when optimism was high, experienced and anticipated stigma was both less strongly associated with depression symptoms and with lower trust in one's HIV care providers compared with when optimism was low. Thus, the effects of experienced stigma on depression symptoms and provider trust were moderated by both resilience and optimism, but the effects of anticipated stigma were moderated only by optimism. Our findings suggest that in addition to their main effects, resilience and optimism may function as buffers against the harmful effects of stigma in health care settings. Therefore, optimism and resilience may be valuable intervention targets to reduce depression symptoms or improve trust in providers among populations that experience or anticipate stigma, such as WLHIV.

Validation of HIV Pre-Exposure Prophylaxis (PrEP) Medication Scales with Youth on PrEP: PrEP Confidence Scale and PrEP Difficulties Scale

Pre-exposure prophylaxis (PrEP) is a lifesaving medical intervention that protects against human immunodeficiency virus (HIV), but to date, PrEP uptake has been limited. PrEP utilization and adherence among youth, including stigmatized and highly vulnerable young sexual and gender minorities, have been exceptionally low across all regions, leading to preventable HIV transmission. Considering the scientific value of measuring and understanding predictors or associations of PrEP adherence, our study team validated two scales: a PrEP Difficulties Scale and a PrEP Confidence Scale tested within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minorities who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported herein. Results for the PrEP Difficulties Scale yielded a four-factor solution (Disclosure, Health Effects, Logistics, and Cost), and results for the PrEP Confidence Scale produced a three-factor solution (Scheduling, Distraction, and Planning). Factor loadings and Cronbach's alphas suggested good internal consistency for both scales. PrEP Confidence Scale subscales were correlated with PrEP adherence, and subscales of both scales were associated with dimensions of social support and PrEP-related stigma. Given the persistence of preventable HIV infections among key populations, multi-level barriers and facilitators to medication adherence, and expansion of PrEP modalities, the PrEP Difficulties Scale and PrEP Confidence Scale have the potential to enhance intervention, exploratory, and mechanistic HIV prevention research.

Associations between early maladaptive schema domains of parents and their adult children: The role of defence styles

Although existing research recognized the associations between early maladaptive schemas (EMSs) of parents and their adult children, the mechanisms that underpin these associations were not fully understood. Therefore, the purpose of the current study was to explore the role of defence styles (DSs) on the associations between two EMS domains (Disconnection/Rejection and Impaired Autonomy) of parents and their adult children. Two hundred and fifteen families (i.e., mother, father, and their adult children) participated in the study. Both parents and their adult children were asked to complete Young Schema Questionnaire-Short Form (YSQ-SF) and Defence Style Questionnaire (DSQ) to assess their EMS domains and DSs. According to the results of the current study, there were significant associations between Disconnection/Rejection and Impaired Autonomy EMS domains of parents and their adult children, and these associations were mediated by only immature DS of parents and their adult children in a serial mediation model. These results contributed to our understanding of the associations between EMS domains of parents and their adult children through immature DSs. Moreover, our findings highlighted the importance of synthesizing the concepts of different theories to enhance our understanding of mental representations in families.

A Moderated Mediation Analysis of HIV and Intersectional Stigmas and Antiretroviral Adherence in People Living with HIV in the Dominican Republic

Experiencing HIV and intersectional stigmas in healthcare settings may affect antiretroviral treatment (ART) adherence among people with HIV (PWH), given their need for frequent interactions with clinical settings and healthcare providers. Considering the importance of reducing stigmas to promote well-being and the need to elucidate how stigma influences health across various settings, we examined how experienced HIV stigma in Dominican Republic healthcare settings impacts ART adherence through internalized HIV stigma and whether race or sexual orientation stigma moderates this relationship. Participants were 471 PWH (aged 17-71) who were recruited from two HIV clinics in the Dominican Republic in 2021-2022. Results revealed a significant mediation effect (B=-0.10, SE = 0.05, CI [-0.234, - 0.014]) after adjusting for effect of age and time since HIV diagnosis, suggesting that experienced HIV stigma in healthcare settings was associated with more internalized HIV stigma (B = 0.39, SE = 0.11, p = .001), subsequently linked to lower ART adherence (B=-0.26, SE = 0.11, p = .016). The indirect effect was significant at low levels of race stigma (B=-0.16, SE = 0.09, CI [-0.369, - 0.001]) but not at high levels of race stigma (B=-0.06, SE = 0.05, CI [-0.175, 0.038]). This indirect effect was also significant at low levels of sexual orientation stigma (B=-0.19, SE = 0.10, CI [-0.401, - 0.023]) but not at high levels of sexual orientation stigma (B=-0.04, SE = 0.06, CI [-0.160, 0.074]). These findings suggest that addressing experienced HIV stigma in Dominican Republic healthcare settings, along with various dimensions of HIV-related stigma (e.g., internalized stigma) and intersecting stigmas (e.g., race, sexual orientation), is vital for improving health outcomes, such as optimal ART adherence.

Development and validation of the mpox stigma scale (MSS) and mpox knowledge scale (MKS)

BACKGROUND

Few validated brief scales are available to measure constructs that may hinder mpox-related prevention and care engagement, such as knowledge and stigma. Both are highly salient barriers to infectious disease care and disease understanding, precursors to evaluating one's risk and need to, for example, accept vaccination. To address this gap, we developed and validated the Mpox Stigma Scale (MSS) and Mpox Knowledge Scale (MKS).

METHODS

As part of a full-scale clinical trial, we offered an optional mpox survey to participants who self-identified as African American or Black, were 18-29 years old, and lived in Alabama, Georgia, or North Carolina (2023, N = 330). We calculated psychometric properties through confirmatory factor analyses (CFA) and applied Comparative Fit Index (CFI), Goodness of Fit Index (GFI), and Tucker-Lewis Index (TLI) values equal to or exceeding 0.90 and Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Square Residual (SRMR) values less than 0.08 to determine adequate model fit. We computed internal reliability using Cronbach's alpha and calculated Pearson or Spearman correlation coefficients between the MSS and MKS and related variables.

RESULTS

For the MSS, CFA results showed that the one-factor model fit the data well (χ2(df = 5, N = 330) = 34.962, CFI = 0.97, GFI = 0.99, TLI = 0.94, RMSEA = 0.13, SRMR = 0.03). For the MKS, the one-factor model provided a good fit to the data (χ2(df = 6, N = 330) = 8.44, CFI = 0.99, GFI = 0.99, TLI = 0.95, RMSEA = 0.15, SRMR = 0.02). Cronbach's alphas were MSS = 0.91 and MKS = 0.83, suggesting good to excellent reliability. The MSS was correlated with the MKS (r = .55, p < .001), stigmatizing attitudes (r = .24, p < .001), attitudes towards mpox vaccination (r=-.12, p = .030), and worry about contracting mpox (r = .44, p < .001). The MKS was correlated with worry about contracting mpox (r = .30, p < .001) and mpox disclosure (r=-.16, p = .003).

CONCLUSIONS

The MSS and MKS are reliable and valid tools for public health practice, treatment and prevention research, and behavioral science. Further validation is warranted across populations and geographic locations.

Mpox Knowledge Among Black Young Adults in the Southern United States

PURPOSE

Mpox disproportionately impacts Black people and young adults, yet the beliefs and knowledge of mpox among groups at elevated risk remain unclear. Therefore, we assessed mpox knowledge among Black young adults to inform public health efforts.

METHODS

We surveyed a sample (n = 330) of young Black adults (aged 18-29 years) in Alabama, Georgia, and North Carolina using nine true-or-false questions to assess their mpox knowledge.

RESULTS

Correct response rates varied (26%-96%). Approximately 26% were unaware of the mpox vaccine, and almost 21% incorrectly thought the chickenpox vaccine conferred protection against mpox. Females demonstrated statistically significantly higher mpox knowledge than males across 33% of indicators.

DISCUSSION

There were no statistically significant differences between states, suggesting that a regional approach may be suitable to improve knowledge. Findings underscore the importance of education and public health initiatives to address mpox knowledge gaps, particularly among Black young adults, to improve public health preparedness.

HIV and intersectional stigma among people living with HIV and healthcare workers and antiretroviral therapy adherence in the Dominican Republic

BACKGROUND

HIV-related stigma, discrimination, and social marginalization undermines optimal HIV care outcomes. More research examining the impact of HIV-related stigma, discrimination, other interlocking forms of oppression, and antiretroviral therapy (ART) adherence is needed to optimize HIV treatment programming. This study uses data from two clinics in the Dominican Republic to examine client and healthcare worker (HCW) perceptions of HIV and intersectional stigmas among people living with HIV.

METHODS

Surveys exploring demographics, HIV-related stigma, various dimensions of discrimination (race/ethnicity, HIV status, sexual orientation), healthcare engagement, and medication adherence were collected from 148 clients and 131 HCWs. Analysis of variance was conducted to examine differences in stigma by clinic and logistic regressions were used to determine predictors of optimal client medication adherence.

RESULTS

Perceived discrimination in healthcare facilities due to clients' sexual orientation retained significance in crude and multivariable logistic regression models and was negatively associated with ART adherence (aOR:0.79; 95% CI:0.66, 0.95).

DISCUSSION

Findings highlight the importance of implementing strategies to address stigma, discrimination, and social marginalization, particularly within healthcare facilities.

Associations Between PrEP Stigma, PrEP Confidence, and PrEP Adherence: Conditional Indirect Effects of Anticipated HIV Stigma

BACKGROUND

Research has linked stigma surrounding preexposure prophylaxis (PrEP) to poor HIV prevention outcomes, including PrEP adherence. However, there remains a limited understanding of the mechanisms through which PrEP stigma affects PrEP adherence, specifically among sexual and gender minority (SGM) youth. In this study, we aimed to investigate the indirect effect of PrEP stigma on PrEP adherence through PrEP confidence and the moderating role of anticipated HIV stigma.

METHODS

Participants included 235 SGM youth, assigned male sex at birth, aged 16-24, and self-reported HIV-negative, with an active PrEP prescription from the Prepared, Protected, emPowered randomized controlled trial. Participants were recruited from 9 clinics in the United States between 2019 and 2021. Using baseline data, we tested cross-sectional indirect and conditional indirect effects using the Statistical Package for the Social Sciences Process with confidence intervals and 2000 resamples.

RESULTS

We found significant indirect effects, suggesting that PrEP stigma was negatively associated with PrEP confidence, which in turn resulted in both monthly and weekly optimal PrEP adherence (Indirect effects: B = -0.11, Standard Error [SE] = 0.05, CI: [-0.244 to -0.032]; B = -0.09, SE = 0.04, CI: [-0.191 to -0.014], respectively). Anticipated HIV stigma moderated these indirect effects (B = -0.11, SE = 0.08, CI: [-0.315 to -0.001]; B = -0.09, SE = 0.06, CI: [-0.245 to -0.001], respectively), suggesting that the conditional indirect effects were significant at high but not low levels of anticipated HIV stigma.

CONCLUSION

Results suggest that SGM youth who are on PrEP anticipating HIV stigma experience a compounding effect of PrEP stigma on PrEP confidence, consequently leading to suboptimal adherence. Interventions addressing the intersectionality of PrEP and HIV stigmas and enhancing confidence could improve PrEP adherence, particularly among SGM youth.

Patient Health Literacy and Communication with Providers Among Women Living with HIV: A Mixed Methods Study

In this mixed-methods study, we examine the relationship between provider communication and patient health literacy on HIV continuum of care outcomes among women living with HIV in the United States. We thematically coded qualitative data from focus groups and interviews (N = 92) and conducted mediation analyses with quantitative survey data (N = 1455) collected from Women's Interagency HIV Study participants. Four qualitative themes related to provider communication emerged: importance of respect and non-verbal cues; providers' expressions of condescension and judgement; patient health literacy; and unclear, insufficient provider communication resulting in diminished trust. Quantitative mediation analyses suggest that higher health literacy is associated with higher perceived patient-provider interaction quality, which in turn is associated with higher levels of trust in HIV providers, improved antiretroviral medication adherence, and reduced missed clinical visits. Findings indicate that enhancing provider communication and bolstering patient health literacy could have a positive impact on the HIV continuum of care.

Adolescent Youth Survey on HIV Prevention and Sexual Health Education in Alabama: Protocol for a Web-Based Survey With Fraud Protection Study

BACKGROUND

In Alabama, the undiagnosed HIV rate is over 20%; youth and young adults, particularly those who identify as sexual and gender minority individuals, are at elevated risk for HIV acquisition and are the only demographic group in the United States with rising rates of new infections. Adolescence is a period marked by exploration, risk taking, and learning, making comprehensive sexual health education a high-priority prevention strategy for HIV and sexually transmitted infections. However, in Alabama, school-based sexual health and HIV prevention education is strictly regulated and does not address the unique needs of sexual and gender minority teenagers.

OBJECTIVE

To understand knowledge gaps related to sexual health, HIV prevention, and pre-exposure prophylaxis (PrEP), we conducted the Alabama Youth Survey with individuals aged 14-17 years. In the survey, we also evaluated young sexual and gender minority individuals' preferences related to prevention modalities and trusted sources of health information.

METHODS

Between September 2023 and March 2024, we conducted a web-based survey with 14- to 17-year-olds who are assigned male at birth, are sexually attracted to male youth, and lived in Alabama. Half of the study's participants were recruited through community partners, the Magic City Acceptance Academy and Magic City Acceptance Center. The other half were recruited on the web via social media. A 7-step fraud and bot detection protocol was implemented and applied to web-based recruitment to reduce the likelihood of collecting false information. Once data are ready, we will compute frequencies for each measure and construct summary scores of scales, such as HIV and PrEP knowledge, to determine internal consistency. Using multivariable logistic regression, we will examine associations between personal characteristics of survey respondents and key constructs using SPSS 29 (IBM Corp) or SAS 9.4 (SAS Institute).

RESULTS

Analyses are ongoing (N=206) and will conclude in June 2025. Preliminary results include a sample mean age of 16.21 (SD 0.88) years; about a quarter identified as transgender or gender nonconforming, with 6% stating their gender as a transgender woman. A total of 30% self-reported their race as African American or Black; 12% were Hispanic or Latinx. More than half reported being sexually active in the past 6 months. Primary data analyses will be completed in mid-2025. If findings are promising, results will be used as preliminary data to support the development of an intervention to address knowledge gaps and prevention preferences.

CONCLUSIONS

If the study is successful, it will yield information on HIV knowledge, PrEP awareness, PrEP preferences, and related outcomes among sexual and gender minority teenagers in Alabama, an underserved, hard-to-reach, but also high-priority population for public health efforts to Ending the HIV Epidemic.

Association of experienced stigma in healthcare settings with health outcomes among Black women living with HIV: Mediating roles of internalized stigma, anticipated stigma, and trust in HIV care

BACKGROUND

Black women living with HIV (WLHIV) often have suboptimal ART adherence due to a multitude of social and structural barriers, including HIV-related stigma. Trust in healthcare providers plays a significant role in adhering to ART and is likely lower among Black WLHIV compared to their White counterparts. This study examined the relationship between experienced stigma in healthcare settings and ART adherence and viral suppression through anticipated stigma in healthcare settings, internalized stigma, and medical mistrust.

PARTICIPANTS/PROCEDURES

Participants included Black WLHIV from the Women's Interagency HIV Study (WIHS). We conducted serial mediation analyses where experienced HIV stigma in healthcare settings is associated with higher anticipated or internalized HIV stigma, leading to higher mistrust in HIV care providers, and ultimately, to lower ART adherence and viral suppression, adjusting for demographic and clinical covariates.

RESULTS

Of the 1,060 WLHIV, approximately 84% achieved optimal ART adherence, and 65% had an undetectable viral load. Serial mediation analyses suggested significant indirect associations between experienced stigma in healthcare settings and ART adherence or viral suppression. Specifically, experienced stigma was associated with higher anticipated or internalized stigma, which was associated with mistrust in HIV care providers, resulting in lower ART adherence and reduced likelihood of undetectable viral load.

CONCLUSIONS

Interventions could focus on training healthcare providers to address implicit biases and create supportive healthcare environments. Integrating mental health support to reduce internalized stigma and using community engagement and education to address anticipated stigma may further improve trust in providers, leading to better health behaviors and outcomes.

Relationships Between Vaccine Knowledge, Hesitancy, and Conspiracy Beliefs on COVID-19, Influenza, and HPV Vaccination

INTRODUCTION

The COVID-19 pandemic highlighted the centuries old issue of vaccine hesitancy and exposed healthcare inequities harming Black young adults. Despite vaccines being able to reduce COVID-19, human papillomavirus (HPV), and influenza morbidity and mortality, they are underutilized. An examination of socio-behavioral factors to understand motivators and barriers to vaccine uptake within Black communities is necessary to improve preventative health.

METHODS

We conducted an online survey of 360 Black young adults, aged 18 and 29 years in the southern United States. Participants were part of a larger randomized-controlled trial which evaluated a digital health intervention for receiving the COVID-19 vaccine. A correlation analysis and a series of logistic regressions were performed to examine the relationships between vaccination knowledge, hesitancy, and conspiracy beliefs for vaccination status for COVID-19, HPV, and influenza.

RESULTS

Vaccine hesitancy and conspiracy beliefs were negatively associated with COVID-19 vaccination (adjusted odds ratio (AOR) = .45, confidence interval (CI) [.284, .722], p < .001; AOR = .37, CI [.217, .628], p < .001, respectively, but vaccination knowledge was not (p = .295). Vaccination hesitancy was negatively associated with ever having accepted HPV vaccination (AOR = .66, CI [.477, 1.56], p = .011). Vaccination hesitancy, conspiracy beliefs, and knowledge were not significantly associated with influenza vaccination.

CONCLUSIONS

Vaccine hesitancy remains a pertinent factor affecting southern Black young adults. Vaccine-related conspiracy beliefs emerged amidst the COVID-19 pandemic and was significant for refusal of the COVID-19 vaccine. Results indicate the need for continued public health efforts to address vaccine hesitancy and conspiracies among southern Black young adults and providing reputable information from trusted sources recognized by this population.

Greater Improvements in Vaccination Outcomes Among Black Young Adults With Vaccine-Resistant Attitudes in the United States South Following a Digital Health Intervention: Latent Profile Analysis of a Randomized Control Trial

Background

Negative attitudes toward vaccines and suboptimal vaccination rates among African American and Black (Black) Americans have been well documented, due to a history of medical racism and human rights violations in the United States. However, digital health interventions (DHI) have been shown to address racial disparities in several health outcomes, such as cardiovascular disease, HIV, and maternal health. The Tough Talks COVID (TT-C) study was a randomized controlled trial of a DHI designed to empower Black young adults in the United States South to make informed, autonomous decisions about COVID-19 vaccine uptake by addressing structural barriers and misinformation about vaccines.

Objective

Our objective was to identify subgroups of Black young adults with various vaccine attitudes at baseline and determine the subgroups for which the TT-C DHI was most impactful.

Methods

Black young adults aged 18-29 years in Alabama, Georgia, and North Carolina who were unvaccinated or insufficiently vaccinated against COVID-19 completed three online surveys over three months (N=360). Latent profile analysis was used to identify subgroups based on general vaccine attitudes at baseline, including hesitancy, confidence, knowledge, conspiracy beliefs, and mistrust. Logistic regression was used to examine the associations between latent profiles and vaccine uptake, and linear regression was used to examine changes in vaccine attitudes at three months post-randomization. Modification of the TT-C DHI's effects was assessed by latent profiles.

Results

Three latent profiles emerged: vaccine-receptive (n=124), vaccine-neutral (n=155), and vaccine-resistant (n=81). Political affiliation, income, social support, and recent flu vaccination differed significantly between the three subgroups (P<.05). Vaccine uptake was not significantly different by subgroup, and the TTC-DHI did not have differing effects on uptake across subgroups. However, the DHI had the strongest effect-with statistically significant measures of association (P<.05) and interaction P values (P<.10)-among the baseline vaccine-resistant and vaccine-neutral subgroups compared to the vaccine-receptive subgroups at three months in improving vaccine hesitancy, confidence, and conspiracy beliefs at three months: vaccine-resistant difference: -0.40 (-0.76 to -0.37), 0.39 (0.02 to 0.75), and -0.47 (-0.86 to -0.09); vaccine neutral difference: -0.36 (-0.52 to -0.19), 0.35 (0.18 to 0.51), and -0.24 (-0.44 to -0.03). The DHI had no effects on these outcomes among the vaccine-receptive subgroup.

Conclusions

Our findings revealed subgroups of Black young adults in the United States South with different vaccination attitudes, for which the TT-C intervention had differing effects. Black young adults who are vaccine-resistant or vaccine-neutral may experience larger gains from a digital vaccine intervention. Future work aimed at improving vaccination outcomes could target these populations to maximize resource efficiency and drive the greatest improvements in vaccine outcomes.

Living with HIV during COVID-19: knowledge and worry about COVID-19, adherence to COVID-19-related precautions, and HIV health outcomes

The COVID-19 pandemic has been profound impacts on mental and physical health of individuals with chronic diseases. Thus, it is important to understand the effects of the COVID-19 pandemic on people living with HIV. We aimed to assess the association between COVID-19-related knowledge and worry, HIV-related health practices and outcomes, and adherence to precautions related to COVID-19, and possible associations of these factors with HIV treatment outcomes (ART adherence and viral load). A cross-sectional survey was conducted between October 2020 and February 2021 among 291 PLWH at two large university hospital HIV clinics in Izmir, Turkey. Additionally, the most recent HIV-RNA load, CD4 count was recorded using medical records. Logistic regression analyses were performed to determine predictors of self-reported adherence to COVID-19-related precautions, ART adherence and undetectable viral load. COVID-19-related worry, COVID-19-related knowledge, and ART adherence were significant predictors of adherence to COVID-19-related precautions. Furthermore, adherence to COVID-19-related precautions was a significant predictor of both ART adherence and undetectable viral load. Findings provide a unique aspect of the interrelations of COVID and living with HIV. Since health behaviors and outcomes for COVID-19 and HIV seem to be interrelated, treatment practices and interventions that address these simultaneously may enhance their efficacy.

Evaluating concurrency and gaps between self-report and vaccine card data for COVID-19 vaccination

We compared self-reported vaccination to vaccine card data to assess concurrency in a sample of Black young adults in Georgia, Alabama, and North Carolina. We described vaccine card versus self-reported data over time and examined discrepancies in reporting between these two sources. Results indicated strong currency suggesting collection of self-reported data may be an acceptable proxy to requiring official vaccine documentation. However, since 58 % of participants did not upload a vaccine card, finding should be applied with caution. Minor differences were found and were generally due to boosters that were self-reported but were not on cards. The discrepancy in number of vaccines and boosters was likely because COVID-19 vaccination has become routine and vaccine cards are not being updated regularly. At this stage in the pandemic and for other vaccinations that become routine and are administered at pharmacies, self-report may be a reliable indication of the number of vaccinations received.

Prepared, Protected, EmPowered (P3): Primary Results of a Randomized Controlled Trial Using a Social Networking, Gamification, and Coaching App to Promote Pre-exposure Prophylaxis (PrEP) Adherence for Sexual and Gender Minority (SGM) Youth Living in the United States

The population-level reductions in HIV incidence attributed to pre-exposure prophylaxis (PrEP) have not been fully realized among sexual, gender, and racial/ethnic minority youth. P3 (Prepared, Protected, emPowered) is a comprehensive mobile application (app) intervention developed to support PrEP adherence through gamification, medication tracking, and social engagement. A randomized controlled trial was conducted with 246 young men who have sex with men (YMSM) and young transgender women who have sex with men (YTWMSM) currently on or planning to begin PrEP. Participants were randomized in a 1:1:1 ratio to: standard of care (SOC), P3 app (P3), or P3 app plus in-app adherence coaching (P3+). Adherence was measured at 3- and 6- months post enrollment by emtricitabine-triphosphate (FTC-TP) and tenofovir-diphosphate (TFV-DP) levels in dried blood spots consistent with PrEP use > 4 days/week. The primary outcome was the difference in the proportion adherent comparing P3/P3+ to SOC. P3/P3+ was associated with a higher proportion adherent compared to SOC for both outcome measures. At 3 months, the estimated increase in the proportion adherent was 0.13 (95% CI: 0.00, 0.27, p: 0.05) and 0.12 (95% CI: -0.03, 0.26, p: 0.11) for TFV-DP and FTC-TP, respectively. Estimated adherence was higher, but not statistically different, in P3+ compared to P3, for both TFV-DP and FTC-TP. Receipt of P3 (P3 or P3+) is associated with an increase in PrEP adherence among YMSM and YTWSM at 3 months. Additional analyses to discern the role of app usage and sociodemographic and behavioral factors on intervention effects are warranted.
