Evaluating Innovative Weight Reduction Strategies for College Students

描述（由申请人提供）：本研究的目的是开发和测试创新策略，以帮助预防两年制社区或技术学院的大学生不健康的体重增加。我们在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来完善，将基于社会生态和社会网络模型，学生随机分配到不同的条件。将招募bmi在18.5 - 29.9之间的学生（n=600）参加随机干预试验。在初步筛选和同意程序之后，学生将完成基线测量，包括：身体成分评估；抽血和血压；病史和体重史；24小时膳食电话召回；对于子样本，7天的加速度计数据；行为和社会心理调查；还有一份家庭食品清单。基线评估完成后，学生将被随机分为干预组和对照组。研究的密集干预阶段持续一个学期，将包括三种干预方法进行评估，包括：1)设计为1学分的大学课程的网络课程（WBC）；2)利用电子、群体和个人信息的个性化干预（PI），以及利用生态瞬时评估的反馈；3)增强的网络课程（WBC+E）。所有干预方法的内容重点都是针对与健康体重维持相关的四种行为，包括健康饮食、积极活动并减少久坐时间、充足睡眠和管理压力。支持性干预阶段随后将使用Facebook或类似的在线社交网络网站创建虚拟社交网络支持（SNS）干预，以加强、告知和鼓励来自三个干预部门的所有参与者之间的交流和支持。SNS将由经过培训的同行领导者领导，这些领导者将在试验的第一阶段确定。控制组学生将收到他们的健康评估、关于保持健康体重的现有公共卫生信息以及他们所在学校校园提供的卫生服务信息。将评估干预方法的有效性和可持续性。相关性（见说明）：年轻人已被确定为不健康体重增加风险最大的人群之一。上两年制大学的年轻人可能特别容易受到影响，因为他们通常来自低收入家庭，要兼顾全职工作、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面临更大的超重风险。（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)
