Evaluating Innovative Weight Reduction Strategies for College Students

描述（由申请人提供）：本研究的目标是开发和测试创新策略，以帮助预防参加两年制社区或技术学院的大学生不健康的体重增加。我们为第二阶段提出的干预措施将基于社会生态和社交网络模型，并将通过我们在第一阶段的形成经验进行完善，学生将被随机分配到不同的条件。将招募BMI在18.5至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小时饮食电话召回;对于子样本，7天的加速度计数据;行为和心理社会调查;和家庭食物清单。完成基线评估后，学生将被随机分为干预条件或对照条件。研究的强化干预阶段，持续一个学期，将包括三种干预方法进行评估，包括：1）基于网络的课程（WBC），旨在作为一个1学分的大学课程提供; 2）个性化的干预（PI）使用电子，团体和个人的信息和反馈，使用生态瞬时评估;和3）增强的基于网络的课程（WBC+E）。所有干预方法的内容重点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，获得充足的睡眠和管理压力。在支助干预阶段之后，将利用Facebook或类似的在线社交网站创建虚拟社交网络支助干预，以加强、通报和鼓励三个干预分支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人领导，这些领导人将在试验第1阶段确定。对照学生将收到他们的健康评估，现有的公共卫生信息，保持健康的体重和信息，有关健康服务提供的学校的校园。将对干预办法的有效性和可持续性进行评价。.相关性（见说明）：年轻人已被确定为最危险的人群之一，不健康的体重增加。参加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，并且正在全职工作，上学，并且经常是父母。他们的饮食、活动、睡眠和压力管理模式使他们处于更大的超重风险中。(End摘要）

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)
