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)

描述（由申请人提供）：这项研究的目的是制定和测试创新策略，以帮助防止参加2年社区或技术学院的大学生体重增加不健康。我们针对第2阶段提出的干预措施将通过我们在第1阶段的形成性经验来完善，将基于社会生态和社交网络模型，学生随机地将学生与条件随机分配。将招募具有18.5至29.9之间的BMI的学生（n = 600）参加随机干预试验。在初始筛选和同意程序之后，学生将完成包括：身体成分评估的基线措施；抽血和血压；医疗和体重历史； 24小时的饮食电话召回；对于子样本，加速度计数据为7天；行为和社会心理调查；和家庭食品清单。完成基线评估后，学生将被随机分为干预条件或控制条件。持续一个学期的研究的密集干预阶段将包括三种要评估的干预方法，包括：1）基于Web的课程（WBC），旨在作为1个学分的大学课程提供； 2）使用电子，组和个人信息以及使用生态时刻评估的个性化干预（PI）； 3）一个增强的基于Web的课程（WBC+E）。所有干预方法的内容都针对与健康体重维持有关的四种行为，包括吃健康的饮食，积极和减少久坐的时间，足够的睡眠和管理压力。受支持的干预阶段将遵循使用Facebook或类似的在线社交网站来创建虚拟社交网络支持（SNS）干预措施，以加强，鼓励所有参与者在三个干预组中的交流和支持。 SNS将由受过训练的同伴领导者领导，这些领导者将在试验的第1阶段中确定。控制学生将获得他们的健康评估，现有的公共卫生信息，以保持健康体重以及有关学校校园提供的健康服务的信息。将评估干预方法的有效性和可持续性。 。相关性（请参见说明）：年轻人被确定为最大风险体重增加风险的人群之一。参加2年大学的年轻人可能特别容易受到伤害，因为他们经常来自低收入的家园，并且正在全职工作，上学，通常是父母。他们有饮食，活动，睡眠AHD压力管理模式，使他们面临超重的风险。 （抽象的结尾）
