Background: Since severe obesity in youth (BMI for age ≥120th percentile) has been steadily increasing, intensive clinical intervention is necessitated, which is often delivered in specialized pediatric obesity clinics. Since the home environment and parental behavioral modeling are two of the strongest predictors of child weight loss during behavioral weight loss interventions, a family-based treatment approach is warranted. This strategy has been moderately successful in our existing, evidence-based pediatric weight management program (Brenner FIT), but since programs such as Brenner FIT rely on face-to-face delivery of programmatic elements, the dose delivered is limited by the time constraints experienced by families enrolled in treatment. Therefore, the purpose of this study is to refine and pilot a tailored, mobile (mHealth) component to augment an existing, evidence-based pediatric weight management program (Brenner FIT) to determine acceptability from a patient and clinical staff perspective, feasibility, and economic costs relative to the established weight management protocol alone [i.e., Brenner FIT vs. Brenner FIT + mHealth (Brenner mFIT)]. Primary Aim 1: Finalize an intervention for adolescent youth with obesity, consisting of podcasts/videos and electronic self-monitoring, to promote reduced caloric intake and increase physical activity. Primary Aim 2: Pilot the intervention in dyads (n = 40) recruited from a pediatric weight loss clinic, to establish acceptability and feasibility of the intervention relative to standard care (n = 40). Secondary Aim: To establish costs associated with development and implementation of mHealth components when delivered with the Brenner FIT program. Study design: For this project, we will randomize 80 youth with obesity (13 – 18yrs) and a caregiver (dyads) to the Brenner FIT condition or the Brenner mFIT condition. All participants will complete baseline measures prior to randomization, and at three and six months. All youth participants will receive a commercially available activity monitor. Caregivers will receive podcasts with a story about a caregiver supporting weight loss in a child by providing healthy foods/activities for his/her family, including healthy eating and physical activity information. Children will receive animated videos that contain healthy eating and physical activity messaging, with an engaging story of a child losing weight. All participants will have access to a website and mobile apps where they will track weight, diet, and physical activity for themselves (youth) or their child (parents). Based on their reports of weight, eating, and physical activity, the messaging received from clinical staff by the families will be individually tailored to promote healthy behaviors and overcome perceived barriers. The proposed research is innovative in that it explicitly incorporates theory into the intervention and evaluation components of the project and builds upon an existing literature on mHealth interventions that use mobile technology.

背景：由于青少年严重肥胖（年龄BMI ≥ 120百分位数）一直在稳步增加， 需要进行强化的临床干预，这通常在专门的儿科肥胖症诊所进行。 由于家庭环境和父母的行为模式是两个最强的预测儿童 在行为减肥干预期间，需要采取以家庭为基础的治疗方法。这 在我们现有的以证据为基础的儿科体重管理中， 计划（Brenner FIT），但由于Brenner FIT等计划依赖于面对面的方案交付， 在这些要素中，所提供的剂量受到参加治疗的家庭所经历的时间限制的限制。 因此，本研究的目的是完善和试点量身定制的移动的（mHealth）组件，以增强 现有的基于证据的儿科体重管理计划（Brenner FIT）来确定可接受性 从患者和临床工作人员的角度来看，可行性和相对于既定权重的经济成本 单独的管理协议[即，Brenner FIT与Brenner FIT + mHealth（Brenner mFIT）]。 主要目标1：最后确定针对肥胖青少年的干预措施，包括播客/视频， 电子自我监测，以促进减少热量摄入和增加体力活动。 主要目的2：在从儿科减肥诊所招募的二元组（n = 40）中进行干预试验， 确定干预相对于标准治疗的可接受性和可行性（n = 40）。 次要目的：确定与移动医疗组件的开发和实施相关的成本 当与布伦纳FIT计划一起交付时。 研究设计：对于本项目，我们将随机选择80名肥胖青年（13 - 18岁）和一名照顾者（二人组）， Brenner FIT条件或Brenner mFIT条件。所有参与者将完成基线测量 在随机化之前，以及在3个月和6个月时。所有青年参与者都将获得一份 活动监控器照顾者将收到一个关于照顾者支持减肥的故事的播客， 为儿童的家人提供健康食品/活动，包括健康饮食和体育活动 信息.孩子们将收到包含健康饮食和体育活动信息的动画视频， 讲述一个孩子减肥的故事所有参与者都可以访问网站和移动的应用程序 在那里，他们将跟踪自己（青少年）或孩子（父母）的体重、饮食和体育活动。基于 他们的体重，饮食和身体活动报告，家庭从临床工作人员那里收到的信息 将为个人量身定制，以促进健康的行为和克服感知障碍。拟议 研究是创新的，因为它明确地将理论纳入干预和评估的组成部分， 该项目是在现有的关于使用移动的技术的移动保健干预措施的文献基础上进行的。
