Latino STYLE: Preliminary Findings From an HIV Prevention RCT Among Latino Youth

Meta-analysis of the effectiveness of educational programs about HIV prevention on knowledge, attitude, and behavior among adolescents

The prevalence of human immunodeficiency virus (HIV) among adolescents is on the rise due to a lack of comprehensive knowledge, leading to suboptimal attitudes and behaviors, which emphasizes the critical need for targeted interventions. The aim of this review study was to evaluate the effectiveness of educational interventions for HIV prevention among adolescents by assessing their impact on knowledge, attitude, and behavior. A systematic review of seven databases: PubMed, Science Direct, Cochrane, JSTOR, Embase, Scopus, and EBSCO were identified, and 14 eligible randomized controlled trials published until June 2023 were included. Two independent authors assessed quality appraisal using the Risk of Bias 2.0. Outcomes were measured using the standard mean difference (SMD) with random effects model and a 95% confidence interval. Subgroup analyses and meta-regression were performed to explore heterogeneity. The results showed significant improvements in participants' knowledge (SMD: 1.13, 95%CI: 0.78-1.49), behavior intentions (SMD: 1.22, 95%CI: 0.37-2.07), and attitude (SMD: 0.48, 95%CI: 0.02-0.95) after receiving HIV prevention education programs. Interventions grounded in theoretical principles and incorporating technology, group settings, and audio-visual aids were found to be effective in enhancing knowledge of HIV prevention and promoting behavioral intentions. Peer-led education positively impacted both knowledge and attitude. Moreover, excluding parents from these programs was identified as a crucial factor in improving adolescents' knowledge of HIV prevention. In conclusion, educational programs focused on HIV effectively enhance adolescents' knowledge, attitudes, and behavioral intentions among adolescents. Professionals planning interventions should consider these impactful components in designing comprehensive strategies.

Factors Associated with HIV Testing Among Spanish and English-Speaking Latino Adolescents Aged 13-18

Adolescent Latino men who have sex with men (LMSM) in the U.S. are disproportionately impacted by HIV. However, there has been limited focus on their HIV prevention and risk behaviors. In this study, we examine the rates of HIV testing and explore the significant demographic and healthcare factors that influence HIV prevention among adolescent LMSM. The analysis for this study utilized data collected during the baseline assessment of SMART, a pragmatic trial aimed at evaluating the effectiveness of an online HIV prevention intervention for adolescent LMSM (N = 524). Only 35.5% of participants had ever had an HIV test in their lifetime. Rates of testing increased among adolescent LMSM who had a doctor with whom they spoke about their sexual health (odds ratio: 4.0; 95% confidence interval: 2.1-8.4; P < 0.001) or HIV testing (odds ratio: 5.8; 95% confidence interval: 3.1-10.7; P < 0.001). Out of the 61 participants who took part in the survey conducted in Spanish, only 26% reported ever having an HIV test. Additionally, 24.5% stated that they had discussed their sexual orientation with a doctor, and only 8.2% had undergone HIV testing. Spanish-speaking adolescents who completed the SMART survey were less likely to openly discuss their sexual orientation or sexual health with most people or have a doctor with whom they discussed these topics, compared to those who completed the survey in English. These findings suggest that Spanish-speaking adolescent LMSM may face obstacles in accessing HIV prevention services in the U.S.

Family-based interventions in youth to prevent HIV/AIDS: A systematic review

Parents are primary sex educators of their teenagers and also function as resources for advice and information about sexual decision-making and partner selection. So far, various family-based programs were carried out to prevent HIV infection in young people; however, their findings are contradictory and inconclusive. Therefore, we carried out the current systematic review to critically review the available literature regarding the role of family-based interventions among young people to prevent HIV infection. The available online databases including ISI Web of Science, Scopus, and PubMed were searched systematically up to November 2022. The risk of bias in the eligible studies was examined by two independent authors using the Cochrane Collaboration Risk of Bias tool. A total of 7 studies including 4952 participants were enrolled in the current study. They were conducted between 2006 and 2020. On the basis of the available literature, family-based HIV prevention interventions seem to be effective in terms of improving HIV/AIDS knowledge and also parent-youth communication. It seems that family-based interventions in youth to prevent HIV/AIDS are effective; however, further well-designed studies are needed to help the researchers reach a firm conclusion on this issue. The current systematic review may be used by investigators for future studies in terms of settings and the selection of educational approaches. Moreover, it strongly suggested that further studies investigating the role of family-based education in the prevention of HIV/AIDS utilize more sample size and also a more robust educational framework.

Causally Interpretable Meta-analysis: Application in Adolescent HIV Prevention

Endowing meta-analytic results with a causal interpretation is challenging when there are differences in the distribution of effect modifiers among the populations underlying the included trials and the target population where the results of the meta-analysis will be applied. Recent work on transportability methods has described identifiability conditions under which the collection of randomized trials in a meta-analysis can be used to draw causal inferences about the target population. When the conditions hold, the methods enable estimation of causal quantities such as the average treatment effect and conditional average treatment effect in target populations that differ from the populations underlying the trial samples. The methods also facilitate comparison of treatments not directly compared in a head-to-head trial and assessment of comparative effectiveness within subgroups of the target population. We briefly describe these methods and present a worked example using individual participant data from three HIV prevention trials among adolescents in mental health care. We describe practical challenges in defining the target population, obtaining individual participant data from included trials and a sample of the target population, and addressing systematic missing data across datasets. When fully realized, methods for causally interpretable meta-analysis can provide decision-makers valid estimates of how treatments will work in target populations of substantive interest as well as in subgroups of these populations.

Design and rationale for ADAPT+: Optimizing an intervention to promote healthy behaviors in rural, Latino youth with obesity and their parents, using mindfulness strategies

Latino youth living in rural areas represent an ethnic and geographical minority population at increased risk for obesity and obesity-related complications. We previously modified our child obesity intervention to be a multi-family behavioral intervention, Adaptando Dieta y Acción Para Todos (ADAPT), to better meet the needs of our target population, rural Latino youth with obesity (8-12 years old) and their parents. Recognizing the role of parent stress on obesity, the main goal of this study is to 1) further refine and optimize the original ADAPT multi-family behavioral obesity intervention protocol to include mindfulness parent stress reduction strategies (now called ADAPT+) and then 2) assess the feasibility of ADAPT+ implementation via a small randomized control trial (RCT) with rural Latino families. Two aims guide the study. For Aim 1 we conduct a series of focus groups with stakeholders and parents, and then conduct a one-arm trial with both parents and their children to obtain feedback for further refining each of our eight integrated ADAPT+ sessions. Aim 2 tests the acceptability and feasibility of our intervention with multi-family groups of Latinos in two rural communities over time (pre-intervention, post-intervention, 3-month follow-up) in a randomized pilot trial (ADAPT+ vs. Enhanced Usual Care [EUC] comparison). This study is intended to set the groundwork for a larger clinical trial to test ADAPT+'s efficacy to improve rural Latino families' eating and physical activity behaviors.
