Despite intensive efforts to engage people living with HIV in the United States, less than half of the youth aged 13 to 24 years achieve viral suppression. There is a clear and continued need for innovative behavioral programs that support optimizing adherence among young persons with HIV.
There are 3 phases of this project. Phase 1 involves conducting focus groups to obtain feedback from youth about an existing technology-based antiretroviral therapy (ART) adherence intervention. Phase 2 will be used to conduct beta testing with youth to refine and finalize the YouTHrive (YT) intervention. Phase 3 is a randomized controlled trial (RCT) to test the efficacy of the YT intervention among youth living with HIV (YLWH).
In phase 1, we will conduct 6 focus groups with approximately 8 youths (aged 15-19 years) and young adults (aged 20-24 years), each in 3 US cities to obtain (1) feedback from YLWH about the look and feel and content of an existing adult-focused Web-based ART adherence intervention and (2) suggestions for adapting the intervention for YLWH similar to themselves. Phase 2 will involve updating the existing intervention to include features and functionality recommended by YLWH in phase 1; it will conclude with beta testing with 12 participants to gain feedback on the overall design and ensure proper functionality and ease of navigation. For phase 3, we will enroll 300 YLWH in 6 US cities (Atlanta, Chicago, Houston, New York City, Philadelphia, and Tampa) into a 2-arm prospective RCT. Participants will be randomized 1:1 to YT intervention or control group. The randomization sequence will be stratified by city and use random permuted blocks of sizes 2 and 4. Participants randomized to the control condition will view a weekly email newsletter on topics related to HIV, with the exception of ART adherence, for 5 months. Participants randomized to the YT intervention condition will be given access to the YT site for 5 months. Study assessments will occur at enrollment and 5, 8, and 11 months post enrollment. The primary outcome that will be assessed is sustained viral load (VL), defined as the proportion of participants in each study arm who have suppressed VL at both the 5- and 11-month assessment; the secondary outcome that will be assessed is suppressed VL at both the 5- and 11-month assessment between drug-using and nondrug-using participants assigned to the YT intervention arm.
Participant recruitment began in May 2017 for phase 1 of the study. The data collection for aim 3 is anticipated to end in April 2020.
The efficacy trial of the YT intervention will help to fill gaps in understanding the efficacy of mobile interventions to improve ART adherence among at-risk populations.

尽管美国为让感染艾滋病毒者参与进来付出了巨大努力,但年龄在13至24岁的青少年中,实现病毒抑制的比例不到一半。显然,持续需要创新的行为干预项目来支持优化感染艾滋病毒青少年的依从性。
本项目分为三个阶段。第一阶段包括开展焦点小组讨论,以获取青少年对现有基于技术的抗逆转录病毒疗法(ART)依从性干预措施的反馈。第二阶段将用于对青少年进行β测试,以完善并最终确定“青年茁壮成长(YT)”干预措施。第三阶段是一项随机对照试验(RCT),以测试YT干预措施对感染艾滋病毒的青少年(YLWH)的疗效。
在第一阶段,我们将在美国的3个城市分别开展6个焦点小组讨论,每组约8名青少年(年龄在15 - 19岁)和青年成人(年龄在20 - 24岁),以获取:(1)感染艾滋病毒的青少年对现有以成人为重点的基于网络的ART依从性干预措施的外观、感觉和内容的反馈;(2)针对与他们自身类似的感染艾滋病毒青少年调整该干预措施的建议。第二阶段将包括更新现有干预措施,纳入第一阶段感染艾滋病毒的青少年所建议的功能和特性;最后将对12名参与者进行β测试,以获取对整体设计的反馈,并确保功能正常且易于操作。对于第三阶段,我们将在美国的6个城市(亚特兰大、芝加哥、休斯顿、纽约市、费城和坦帕)招募300名感染艾滋病毒的青少年,进行一项双组前瞻性随机对照试验。参与者将按1:1随机分为YT干预组或对照组。随机序列将按城市分层,并使用大小为2和4的随机排列块。随机分配到对照条件的参与者将在5个月内每周查看一份关于艾滋病毒相关主题(抗逆转录病毒疗法依从性除外)的电子邮件通讯。随机分配到YT干预组的参与者将在5个月内访问YT网站。研究评估将在入组时以及入组后5个月、8个月和11个月进行。将评估的主要结局是持续病毒载量(VL),定义为每个研究组中在5个月和11个月评估时病毒载量均得到抑制的参与者比例;将评估的次要结局是在分配到YT干预组的吸毒和非吸毒参与者中,在5个月和11个月评估时病毒载量均得到抑制的情况。
该研究第一阶段的参与者招募于2017年5月开始。预计针对目标3的数据收集将于2020年4月结束。
YT干预措施的疗效试验将有助于填补在了解移动干预措施对改善高危人群抗逆转录病毒疗法依从性疗效方面的空白。
