Dissemination of an Adolescent Obesity Prevention Intervention to Louisiana Schools

摘要 该R15项目的目标是将循证的Switch-MS干预传播到路易斯安那州。这个 更名为路易斯安那州使用数字辅助运动和饮食预防肥胖(ProudMe)将 保留Switch-MS的有效、以学校为基础的组件，但也将收到理论知识丰富的、新颖的 调整以整合基于技术的组件，这些组件是为更具种族多样性的人口量身定做的 路易斯安那州。我们将寻求多名训练有素的学生研究人员的帮助，以实现两个目标。在目标1中，我们将 从12所学校的48个班级招募480名青少年(6-7年级11-13岁)(集群- 随机分为6所ProudMe学校和6所轮候名单对照学校)，以确定 ProudMe对肥胖预防行为和体重状况的干预。在目标2中，我们将收集混合的- 方法来自24名学校实施者(即教师、管理人员和工作人员)、96名青少年和96名 在干预的早期、中期和后期，6所ProudMe学校的家长，以捕捉适应和 执行指标。基于我们之前资助的工作(例如，R21HD090513，PI：Chen博士)，这 该项目将由一个强大的、协作的、跨学科的团队领导，团队成员来自人体运动学， 发展心理学、营养学、儿童肥胖症、计算机科学、统计学和实施 科学。我们的团队已经开发了ProudMe原型，并准备进行Beta测试，然后部署 对这一拟议项目的干预。该项目的出现将大大加强这项研究 路易斯安那州立大学(LSU)的环境--一所以本科生为主的服务机构 由美国国立卫生研究院资助不足。该项目符合路易斯安那州立大学新任校长“奖学金第一”的愿景，因为它 将创造独特的、实用的研究机会，这些机会是路易斯安那州立大学有志于此的学生所无法获得的 寻求生物医学和健康领域的高级教育或职业。我们预计ProudMe的干预将 展示良好的有效性和实施成果，为传播和 实施(D&I)青少年肥胖预防研究。干预将直接受益于 数百名路易斯安那州青少年和他们的家人以及预防肥胖的学校。这些发现将导致 对我们未来R01应用和更广泛传播的ProudMe干预。

Abstract The goal of this R15 project is to disseminate the evidence-based SWITCH–MS intervention to Louisiana. The re-branded Louisiana-based Preventing Obesity Using Digital-assisted Movement and Eating (ProudMe) will retain the effective, school-based components of the SWITCH–MS but will also receive theory-informed, novel adaptations to integrate technology-based components tailored for the more racially diverse populations in Louisiana. We will enlist the aid of multiple trained student researchers to address two aims. In Aim 1, we will recruit 480 adolescents (11-13 years old in 6th-7th grades) from 48 classes across 12 schools (cluster- randomized to 6 ProudMe schools vs 6 wait-list control schools), to determine the effectiveness of the ProudMe intervention on obesity-prevention behaviors and weight status. In Aim 2, we will collect mixed- methods data from 24 school implementers (i.e., teachers, administrators, and staff), 96 adolescents, and 96 parents at the 6 ProudMe schools in early, mid, and late phases of the intervention, to capture adaptation and implementation indicators. Building on our previously funded works (e.g., R21HD090513, PI: Dr. Chen), this project will be led by a strong, collaborative, transdisciplinary team with experts from kinesiology, developmental psychology, nutrition, childhood obesity, computer science, statistics, and implementation science. Our team has developed the ProudMe prototype and is ready to beta test and then deploy the intervention for this proposed project. The advent of the project will significantly strengthen the research environment of the Louisiana State University (LSU) – a primarily undergraduate student serving institution under-funded by the NIH. The project is in line with the new LSU president’s vision of “scholarship first”, as it will create unique, practical research opportunities that are otherwise unavailable for LSU students who aspire to seek advanced education or careers in biomedical and health fields. We expect the ProudMe intervention to demonstrate sound effectiveness and implementation outcomes, adding new insights to the Dissemination and Implementation (D & I) research on adolescent obesity prevention. The intervention will directly benefit hundreds of Louisiana adolescents and their families and schools for obesity prevention. The findings will lead to our future R01 applications and broader dissemination of the ProudMe intervention.
