Poor physical activity (PA) and sleep behaviors in Hispanic adolescents contributes to increased risk for type 2 diabetes. Commonly owned digital devices and services like smartphones and text-messaging are highly used among adolescents and are promising intervention tools for reaching this age group. Personal activity trackers assess activity and sleep, making them ideal tools for addressing these behaviors. We propose to examine the feasibility of a 12-week intervention that uses theoretically grounded text messages and a Fitbit device to improve PA and sleep among Hispanic adolescents with obesity, as compared to a wait-list control group with a Fitbit device only.
Participants (N = 48; 14-16 years) will be randomized (1:1) to the intervention or wait-list control group. Youth in the intervention will receive a Fitbit Charge 5 and daily text messages. Youth in the wait-list control group will receive a Fitbit Charge 5 and information on PA and sleep guidelines.
Feasibility will be examined by collecting process evaluation data on the following criteria: (1) recruit 48 Hispanic adolescents 14-16 years; (2) retain 85% of participants for post-assessments; (3) Fitbit wear ≥4 days/week and respond to 80% of text messages when prompted; (4) ≤10% technical issues; and (5) obtain 80% satisfaction from participants.
This study will advance our knowledge on the feasibility of digital prevention strategies to promote PA and sleep behaviors to reduce T2D risk among Hispanic youth. If feasible, this approach has the potential to be a scalable, cost-effective diabetes prevention strategy among high-risk youth.

西班牙裔青少年的身体活动（PA）和睡眠行为不佳会增加患 2 型糖尿病的风险。智能手机和短信等常用的共同拥有的数字设备和服务在青少年中广泛使用，是接触这一年龄段的有前途的干预工具。个人活动追踪器可评估活动和睡眠情况，因此非常适合解决这些行为问题。我们拟检验一项为期 12 周的干预措施的可行性，该措施使用基于理论的短信和 Fitbit 设备来改善肥胖的西班牙裔青少年的 PA 和睡眠，与仅使用 Fitbit 设备的等待名单对照组相比。
将参与者（N=48；14-16 岁）随机（1:1）分配到干预组或等待名单对照组。干预组的青少年将获得 Fitbit Charge 5 和日常短信。等待名单对照组的青少年将获得 Fitbit Charge 5 和有关 PA 和睡眠指南的信息。
将通过收集以下标准的过程评估数据来评估可行性：（1）招募 48 名 14-16 岁的西班牙裔青少年；（2）保留 85%的参与者进行后期评估；（3）Fitbit 佩戴时间≥每周 4 天，并在提示时回复 80%的短信；（4）技术问题≤10%；（5）参与者满意度达到 80%。
本研究将增进我们对数字预防策略促进 PA 和睡眠行为以降低西班牙裔青少年 2 型糖尿病风险的可行性的认识。如果可行，这种方法有可能成为高风险青少年的一种可扩展、具有成本效益的糖尿病预防策略。
