Fit24: Using technology to improve activity and sleep in Hispanic youth

项目摘要 西班牙裔青少年不成比例地承受肥胖的负担，并表现出更大的2型糖尿病风险 (T2D)与非西班牙裔白色青年相比。这些差异部分是由不健康的起床时间造成的 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风险成人的T2 D风险。然而，很少有研究 为西班牙裔青年开发并测试了T2 D预防干预措施，甚至更少的人关注 改善清醒时间和睡眠行为。像Fitbit活动监视器这样的技术设备已经被 越来越多地被用作肥胖预防干预中的行为改变工具。研究利用了 结合文本消息收发的可穿戴设备在增加成年人的身体活动方面是有效的。 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 少数族裔青年的预防战略。本研究的目的是探讨12周 目标设定干预，利用Fitbit设备和基于自我决定的短信 促进西班牙裔青少年（14-16岁）健康觉醒时间（PA，SB）和睡眠行为的理论（SDT） 老年人）肥胖（BMI%≥ 95）。与西班牙裔青年（N=20）和专家小组（N=6）合作，文本 信息内容将根据先前进行的试验性研究进行调整和改进。混合方法 （调查和采访）将被应用，以确保短信内容坚持SDT，是年龄和 文化上合适。将招募不同的西班牙裔青年样本（N=48），并随机分配至 干预或等待名单对照组。在干预中，青年将接受研究团队的指导 设置每周步数/日数和睡眠时间/夜间目标，Fitbit设备可以自我监控目标的进展， 和理论告知短信，促进行为改变的自主动机。可行性将是 使用招募、数据收集、干预实施和可接受性的先验标准进行评价。 该提案以初步数据为基础，并利用强大的跨学科调查团队来解决 在高危西班牙裔青少年中进行糖尿病预防研究的关键差距。该可行性研究将 有助于提供所需的初步数据，以建立更严格，充分的功效 试验（R 01）。如果发现这种创新方法是可行的，它有可能成为一种负担得起的和可扩展的方法。 以解决方案为导向的方法来预防西班牙裔青年和其他高危青年人群的T2 D。

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.
