Evaluating Innovative Weight Reduction Strategies for College Students

描述(由申请者提供)：这项研究的目标是开发和测试创新的策略，以帮助预防参加两年制社区或技术学院的大学生的不健康体重增加。我们为第二阶段提出的干预措施，将通过我们在第一阶段的形成经验进行完善，将基于社会生态和社会网络模型，学生随机选择条件。体重指数在18.5和29.9之间的学生(n=600)将被招募参加一项随机干预试验。在最初的筛查和同意程序之后，学生们将完成基线测量，其中包括：身体成分评估；抽血和血压；病史和体重史；24小时饮食电话召回；对于子样本，7天加速度计数据；行为和心理社会调查；以及家庭食物库存。在完成基线评估后，学生将被随机分为干预条件或对照条件。这项研究的强化干预阶段将持续一学期，将包括三种干预方法进行评估，包括：1)基于网络的课程(WBC)，旨在作为1学分的大学课程提供；2)使用电子、群体和个人信息以及使用生态瞬时评估反馈的个性化干预(PI)；以及3)增强的基于网络的课程(WBC+E)。所有干预方法的内容重点都针对与健康体重保持相关的四种行为，包括健康饮食、积极活动和减少久坐时间、获得充足的睡眠和管理压力。支助干预阶段之后将利用Facebook或类似的在线社交网站创建一个虚拟社交网络支助干预，以加强、通报和鼓励来自三个干预部门的所有参与者之间的交流和支助。SNS将由训练有素的同行领导人领导，他们将在试验的第一阶段确定。CONTROL学生将收到他们的健康评估，现有的关于保持健康体重的公共卫生信息，以及关于学校校园提供的健康服务的信息。将对干预方法的有效性和可持续性进行评估。。相关性(参见说明)：年轻人已被确定为最有可能出现不健康体重增加的人群之一。上两年制大学的年轻人可能特别脆弱，因为他们通常来自低收入家庭，既要全职工作，又要上学，而且往往是父母。他们的饮食、活动、睡眠和压力管理模式使他们超重的风险更大。(摘要结束)

DESCRIPTION (provided by applicant): The goal of this research is to develop and test innovative strategies to help prevent unhealthy weight gain in college students attending 2-year community or technical colleges. The intervention we propose for Phase 2, and will refine through our formative experiences in Phase 1, will be based on social ecological and social networks model with students randomized to conditions. Students (n=600) with BMIs between 18.5 and 29.9 will be recruited to participate in a randomized intervention trial. After the initial screening and consent procedures, students will complete baseline measures that include: assessment of body composition; a blood draw and blood pressure; medical and weight history; a 24-hour dietary telephone recall; and for a subsample, 7 days of accelerometer data; a behavioral and psychosocial survey; and a home food inventory. After the completion of baseline assessments, students will be randomized into intervention conditions or a control condition. The intensive intervention phase ofthe research, lasting a semester, will include three intervention approaches to be evaluated including: 1) a web-based curriculum (WBC) designed to be offered as a 1 credit college course; 2) a personalized intervention (PI) using electronic, group and individual information and feedback using ecological momentary assessment; and 3) an enhanced web based course (WBC+E). The content focus for all ofthe intervention approaches targets four behaviors related to healthy weight maintenance including eating a healthy diet, being active and reducing sedentary time, getting adequate sleep, and managing stress. The supported intervention phase will follow with the creation of a virtual social network support (SNS) intervention using Facebook or a similar on-line social networking web site to reinforce, inform and encourage exchange and support between all participants from the three intervention arms. The SNS will be led by trained peer leaders that will be identified during phase 1 ofthe trial. Control students will receive their health assessments, existing public health information on maintaining a healthy weight and information regarding health services offered on their school's campus. The effectiveness and sustainability of the intervention approaches will be evaluated. . RELEVANCE (See instructions): Young adults have been identified as one ofthe population groups at greatest risk for unhealthy weight gain. Young adults attending 2-year colleges may be particularly vulnerable as they often come from lower income homes and are juggling working full time, going to school and often are parents. They have dietary, activity, sleep ahd stress management patterns that put them at greater risk for overweight. (End of Abstract)
