项目摘要

DESCRIPTION (provided by applicant): Dr. Nicole Nollen is a counseling psychologist and Assistant Professor in the Department of Preventive Medicine and Public Health at the University of Kansas Medical Center. The candidate's long-term goal is to function as an independently funded clinical investigator focusing on adolescent health risk reduction through behavioral weight control interventions. To accomplish this goal, the candidate has assembled an exceptional mentoring team and proposed a 4 year career development plan focused on coursework, seminars, independent study, expert consultation, and conference attendance to address gaps in her general and content specific research knowledge. Areas to be addressed include the design and conduct of randomized trials (Ellerbeck, Primary Mentor), adolescent nutrition and nutrition assessment (Carlson, Co- Mentor), and the design and implementation of technology-based (Rapoff, Co-Mentor) and adolescent health risk reduction (Goggin, Co-Mentor) behavioral interventions. To further enhance her career development training, the candidate has proposed a pilot study of 50 adolescents (25 per arm) randomized to a handheld computer behavioral intervention (HHC) addressing fruits and vegetables (FV), sweetened beverages, and TV/screen time or a handheld computer assessment only comparison condition (C). The primary aim is to test the feasibility and acceptability of a 3 month intervention delivered to adolescents via handheld computer. Secondary aims are to: 1) explore 3 and 6 month changes in the primary outcome, body mass index (BMI), and obtain effect size estimates for a full-scale R01 trial, 2) explore 3 and 6 month changes in secondary outcomes, FVs, sweetened beverages, TV/screen time, and physical activity, and 3) to evaluate the role of potential mediators on BMI, FV, TV/screen time, physical activity, and sweetened beverages. RELEVANCE (See instructions): Of relevance to public health, the study presents a novel approach to adolescent obesity prevention that may enhance reach and reduce key obstacles (e.g., stigma) to adolescents' participation in obesity prevention trials. If successful, the intervention has the potential to alter the trajectory of overweight and reduce obesity- related morbidity and mortality. Finally, once developed, the intervention could be sustained at little additional cost and extended to other obesity-related lifestyle factors (e.g., physical activity, dietary fat).

描述（由申请人提供）： Nicole Nollen 博士是堪萨斯大学医学中心预防医学和公共卫生系的咨询心理学家和助理教授。候选人的长期目标是作为一名独立资助的临床研究者，专注于通过行为体重控制干预措施降低青少年健康风险。为了实现这一目标，候选人组建了一支出色的指导团队，并提出了一个为期 4 年的职业发展计划，重点是课程作业、研讨会、独立研究、专家咨询和参加会议，以解决她在一般和内容特定研究知识方面的差距。需要解决的领域包括随机试验的设计和实施（Ellerbeck，主要导师）、青少年营养和营养评估（Carlson，共同导师），以及基于技术的（Rapoff，共同导师）和青少年营养评估的设计和实施。降低健康风险（Goggin，共同导师）行为干预。为了进一步加强她的职业发展培训，候选人提议对 50 名青少年（每组 25 名）进行一项试点研究，随机接受手持电脑行为干预 (HHC)，处理水果和蔬菜 (FV)、含糖饮料和电视/屏幕时间或手持电脑仅评估比较条件（C）。主要目的是测试通过手持电脑向青少年提供为期 3 个月的干预的可行性和可接受性。次要目标是：1) 探索主要结局、体重指数 (BMI) 的 3 和 6 个月变化，并获得全面 R01 试验的效应大小估计值，2) 探索次要结局 3 和 6 个月的变化， FV、含糖饮料、电视/屏幕时间和身体活动，以及 3) 评估潜在调节因素对 BMI、FV、电视/屏幕时间、身体活动和含糖饮料的作用。相关性（参见说明）：与公共卫生相关，该研究提出了一种预防青少年肥胖的新方法，可以扩大青少年参与肥胖预防试验的范围并减少主要障碍（例如耻辱）。如果成功，干预措施有可能改变超重轨迹并降低肥胖相关的发病率和死亡率。最后，一旦开发出来，干预措施可以以很少的额外成本持续进行，并扩展到其他与肥胖相关的生活方式因素（例如体力活动、膳食脂肪）。（摘要完）
