The number of youth living with HIV continues to rise, and they are disproportionately represented at each stage of the care continuum. Most relevant to this application, it is estimated that less than half of HIV-infected youth in the United States (US) have been diagnosed with HIV, and AIDS-related deaths among youth have increased over the past decade despite decreased death rates among all other age groups, pointing to the urgent need for increased testing among youth. Black and Latino youth are at increased risk of poor HIV-related outcomes and have disparate testing rates as compared to White youth. Mobile Health (mHealth) technology is a powerful and relevant tool which represents a promising approach for improving outcomes among youth living with HIV. Youth are avid adopters and heavy users of smartphones and digital technologies, and these technologies offer opportunities to tailor interventions to developmental stages and personal needs. Importantly, these technologies are capable of delivering interventions in real-time and in ecologic settings. This creates an opportunity to remotely reach youth through mobile and connected health approaches to strengthen their HIV care continuum engagement and treatment outcomes. In response, our study team has developed the mLab App, an innovative mobile and connected technology that combines HIV prevention information with push notifications/reminders to complete HIV testing and an automated image processing feature to provide accessible, objective, secure, and real-time feedback on home-based OraQuick (lateral flow assay) HIV test results. The mLab App also contains an innovative automated data collection and a results reporting feature. Findings from our preliminary work in New York City indicate that youth perceive the mLab App as useful, easy to use, and effective at improving health outcomes and intend to use the technology. Findings from our preliminary work in Africa support the sensitivity and specificity of the imaging algorithm for interpreting lateral flow assay results. Theoretically-guided by the Health Information Technology Usability Evaluation Model (Health-ITUEM), the proposed project will refine and test a next- generation diagnostic intervention delivered on a mobile platform to improve HIV testing and linkage-to-care outcomes among youth living with and at-risk for HIV. Well in line with the objectives of RFA-MH-18-606, we will conduct a careful, iterative process of technology refinement based on input from end users, experts, and our youth advisory board. We will then enroll 500 high-risk youth (age 17-29 years) in a 12-month RCT to assess differences in HIV testing rates and linkage to care between the intervention (mLab App) and control arm. Finally, we will analyze paradata, defined as auxiliary data that capture details about the process of interaction with the technology, to understand the effect of user engagement of the mLab App on improving HIV testing rates and linkage to care. Interventions delivered through mHealth technology represent a promising approach for improving outcomes among youth. Given the pervasiveness, low cost, and convenience of mobile technology, the mLab App holds promise to help achieve the goals of the National HIV/AIDS Strategy in the US by increasing the number of persons living with HIV who know their serostatus, decreasing HIV-related disparities, and ultimately reducing the risk of HIV transmission and acquisition.

感染艾滋病毒的青年人数继续增加，他们在艾滋病毒/艾滋病的每个阶段所占比例都不成比例。 关怀连续体与此应用程序最相关的是，据估计，在美国， 美国各州被诊断出感染艾滋病毒，在过去十年中，青年人中与艾滋病有关的死亡人数有所增加 尽管所有其他年龄组的死亡率都有所下降，这表明迫切需要增加青年人的检测。 黑人和拉丁裔青年艾滋病毒相关结果不佳的风险增加，与黑人相比， 白色青年。移动的健康（mHealth）技术是一种强大的相关工具，代表了一种有前途的方法 改善感染艾滋病毒的青年的成果。年轻人是智能手机的狂热采用者和重度用户， 数字技术，这些技术提供了机会，使干预措施适应发展阶段， 个人需要。重要的是，这些技术能够实时和生态地提供干预措施。 设置.这创造了一个机会，通过移动的和互联的健康方法远程接触青年， 加强其艾滋病毒护理连续体的参与和治疗成果。作为回应，我们的研究团队开发了 mLab App，一种创新的移动的互联技术，将艾滋病预防信息与推送相结合 通知/提醒以完成HIV检测，以及自动图像处理功能， 客观、安全和实时反馈基于家庭的OraQuick（侧流检测）HIV检测结果。mLab App 还包含创新的自动数据收集和结果报告功能。我们初步工作的结果 在纽约市进行调查表明，年轻人认为mLab App有用、易于使用，并能有效改善健康状况 结果并打算使用该技术。我们在非洲的初步工作结果支持敏感性和 用于解释侧流测定结果的成像算法的特异性。以健康为理论指导 信息技术可用性评估模型（健康-ituem），拟议的项目将完善和测试下一个- 在移动的平台上提供一代诊断干预措施，以改善艾滋病毒检测和与护理结果的联系 在感染艾滋病毒和有感染风险的青年中。根据RFA-MH-18-606的目标，我们将进行 根据最终用户、专家和我们的青年顾问委员会的意见，对技术进行仔细、反复的改进。 然后，我们将招募500名高危青年（年龄17-29岁）参加为期12个月的RCT，以评估艾滋病毒检测率的差异 以及干预（mLab App）和控制臂之间的护理联系。最后，我们将分析paradox，定义为 辅助数据，捕获与技术交互过程的详细信息，以了解用户的影响 移动实验室应用程序参与提高艾滋病毒检测率和与护理的联系。通过以下途径采取的干预措施 移动保健技术是改善青年人成果的一个有前途的办法。鉴于普遍性，低 成本和移动的技术的便利性，mLab应用程序有望帮助实现国家目标， 美国艾滋病毒/艾滋病战略，增加了解其血清状况的艾滋病毒感染者人数，减少 消除与艾滋病毒有关的差距，并最终减少艾滋病毒传播和感染的风险。
