PROJECT SUMMARY Hispanic adolescents are disproportionately burdened by obesity and exhibit greater risk for type 2 diabetes (T2D) compared to non-Hispanic white youth. These disparities are driven in part by unhealthy wake time physical activity (PA) and sedentary behaviors (SB), and short sleep durations. Lifestyle interventions that address these behaviors have effectively reduced T2D risk in high-risk adults. However, few studies have developed and tested T2D prevention interventions for Hispanic youth and even fewer have focused on improving both wake time and sleep behaviors. Technology-based devices like Fitbit activity monitors have been increasingly used as behavior change tools in obesity prevention interventions. Studies that have utilized wearable devices in conjunction with text-messaging have been effective in increasing physical activity in adults. However, more research is needed to test the feasibility of wearable devices as a health promotion and disease prevention strategy among minority youth. The purpose of this study is to examine the feasibility of a 12-week goal-setting intervention that utilizes a Fitbit device and text messages grounded in the Self-Determination Theory (SDT) to promote healthy wake time (PA,SB) and sleep behaviors in Hispanic adolescents (14-16 years old) with obesity (BMI%≥95th). In collaboration with Hispanic youth (N=20) and an expert panel (N=6), text message content will be adapted and refined from a previously conducted pilot study. A mixed methods approach (surveys and interviews) will be applied to ensure that text message content adheres to the SDT and is age and culturally appropriate. A different sample of Hispanic youth (N=48) will be recruited and randomized to the intervention or a wait-list control group. In the intervention, youth will receive guidance from the research team on setting weekly steps/day and hours of sleep/night goals, a Fitbit device to self-monitor progress towards goals, and theory informed text messages that promote autonomous motivation for behavior change. Feasibility will be evaluated using a priori criteria for recruitment, data collection, intervention implementation, and acceptability. This proposal builds on preliminary data and leverages a strong, transdisciplinary investigative team to address critical gaps in diabetes prevention research among high-risk Hispanic adolescents. This feasibility study will be instrumental in providing the preliminary data needed to build towards a more rigorous, fully powered efficacy trial (R01). If this innovative approach is found to be feasible, it has the potential to be an affordable and scalable solution-oriented approach to T2D prevention in Hispanic youth and other populations of high-risk youth.

项目总结 西班牙裔青少年肥胖负担不成比例，患2型糖尿病的风险更大 (T2D)与非西班牙裔白人青年相比。这些差异在一定程度上是由不健康的清醒时间造成的 体力活动(PA)和久坐行为(SB)，以及睡眠时间短。生活方式干预 解决这些行为有效地降低了高危成年人的T2D风险。然而，很少有研究表明 为西班牙裔青年开发和测试了T2D预防干预措施，更少的人专注于 改善醒觉时间和睡眠行为。像Fitbit活动监测器这样基于技术的设备已经 在肥胖预防干预中越来越多地被用作改变行为的工具。已经利用了 可穿戴设备与短信相结合，有效地增加了成年人的体力活动。 然而，还需要更多的研究来测试可穿戴设备作为健康促进和疾病的可行性 在少数族裔青年中实施预防战略。这项研究的目的是检查为期12周的 目标设定干预，利用Fitbit设备和以自决为基础的文本消息 促进西班牙裔青少年(14-16岁)健康清醒时间(PA、SB)和睡眠行为的理论(SDT) 肥胖(BMI%≥第95位)。与西班牙裔青年(N=20)和一个专家小组(N=6)合作，案文 报文内容将根据之前进行的试点研究进行改编和提炼。一种混合方法方法 (调查和访谈)将用于确保短信内容符合SDT，并具有时效性 在文化上是合适的。一个不同的西班牙裔青年样本(N=48)将被招募并随机分配到 干预组或等待名单对照组。在干预中，青少年将接受研究团队的指导 在设定每周步数/白天和睡眠/夜间小时目标时，Fitbit设备可以自我监控实现目标的进度， 理论上提供了短信信息，促进了行为改变的自主动机。可行性将是 使用招聘、数据收集、干预实施和可接受性的先验标准进行评估。 该建议建立在初步数据的基础上，并利用一支强大的跨学科调查团队来解决 高危西班牙裔青少年在糖尿病预防研究方面的严重差距。这项可行性研究将是 有助于提供所需的初步数据，以实现更严格、更充分的功效 试验(R01)。如果这种创新的方法被发现是可行的，它有可能成为一种负担得起和可扩展的 在西班牙裔青年和其他高危青年群体中采取以解决方案为导向的T2D预防方法。
