Translation of social media obesity treatment into two college campus communities

描述（由申请人提供）：从青春期后期到成年早期的过渡期是体重增加的脆弱时期，在这一生命过渡期间，超重/肥胖增加了两倍。在50%上大学的青少年中，从入学到毕业，体重平均增加1.7公斤（女性）和4.2公斤（男性）。这些增加是由大约三分之一的大学生已经超重或肥胖的事实加剧。超重和肥胖对健康的影响是众所周知的;然而，在这一人群中，代谢风险在很大程度上未被研究，未诊断的代谢功能障碍值得关注：26-40%的大学生已经有一个代谢综合征的异常成分。尽管存在这些公共健康风险和负面健康后果，但针对新兴成年人（18- 26岁）和大学校园的循证肥胖治疗计划存在差距。大学校园是开展肥胖治疗项目的理想场所。截至2009年，70.1%的高中毕业生，包括GED获得者，进入大学。此外，18-19岁的青少年中有50%就读于大学。这项研究是基于一项有希望的随机对照试验（RCT）的57名大学生的初步数据，该试验证明了社交媒体提供的减肥治疗的初步疗效。据我们所知，我们的RCT是第一个研究大学生社交媒体减肥治疗的。这项研究的下一步是研究这种类型的计划是否可以翻译到其他大学校园社区。因此，我们建议随机分配450名超重/肥胖的大学生（年龄18- 26岁）就读于两所大学（乔治华盛顿大学和马萨诸塞大学波士顿分校）的两个社交媒体减肥治疗（定制或有针对性）或接触控制。社交媒体治疗包括Facebook群组，以提供社会支持，连通性和干预内容，以及每日短信。我们认为，使用社交媒体作为干预工具将吸引这个习惯于使用技术的年龄组。将在基线、基线后6、12和18个月进行评估，主要结局为18个月时的体重减轻。第二个目的是评估那些在18个月内保持至少5%体重减轻的参与者的代谢危险因素的变化。最后，我们将进行额外的形成性工作，以评估在大学校园实施这种干预措施的可行性，包括评估成本以及使用PRISM（实用，稳健的实施和可持续性模型）模型作为指导的可持续性基础设施。这项研究的结果有可能对大学校园肥胖治疗服务的提供产生重大影响。

DESCRIPTION (provided by applicant): The transitional period from late adolescence to early adulthood is a vulnerable period for weight gain, with a twofold increase in overweight/obesity during this life transition. Among the 50% of adolescents who attend college, weight gain averages 1.7 kg (females) and 4.2 kg (males) from matriculation to graduation. These increases are compounded by the fact that about one-third of college students are already overweight or obese. The health consequences of overweight and obesity are well established; however, metabolic risks are largely unstudied in this population, with undiagnosed metabolic dysfunction of concern: 26-40% of college students already have one abnormal component of the Metabolic Syndrome. Despite these public health risks and negative health consequences, a gap exists for evidence-based obesity treatment programs targeted to emerging adults (18-26y) and available on college campuses. College campuses make ideal locations from which to launch obesity treatment programs. As of 2009, 70.1% of recent high school completers, including GED recipients, enrolled in college. Additionally, 50% of all adolescents ages 18-19 years old are enrolled in college. The proposed study is based on promising pilot data of a randomized controlled trial (RCT) of 57 college students which demonstrated the initial efficacy of a social media delivered weight loss treatment. To our knowledge, our RCT was the first to examine social media weight loss treatments for college students. The next step in this research is to examine whether this type of program can be translated to other college campus communities. Thus, we propose to randomly assign 450 overweight/obese college students (ages 18- 26) enrolled at two colleges (George Washington University and University of Massachusetts-Boston) to one of two social media weight loss treatments (Tailored or Targeted) or a contact control. The social media treatments consist of Facebook groups to provide social support, connectedness and intervention content, as well as daily text messages. We posit that the use of a social media as an intervention tool will appeal to this age group who are accustomed to technology use. Assessments will be conducted at baseline, 6, 12, and 18 months post baseline, with the primary outcome being weight loss at 18 months. The secondary aim is to evaluate changes in metabolic risk factors among those participants who have maintained at least 5% weight loss at 18 months. Finally, we will conduct additional formative work to evaluate the implementation feasibility of this intervention on college campuses, including an assessment of costs as well as the sustainability infrastructure using the PRISM (Practical, Robust Implementation and Sustainability Model) model as a guide. The results of this study have the potential to significantly impact the delivery of obesity treatment services on college campuses.
