Closing the Energy Gap To Prevent Weight Gain

描述（由申请人提供）： 全面解决与成功预防体重增加相关的研究问题的能力需要体重调节的生理和行为方面的知识。该K 01职业发展奖的主要目标是使戴维博士能够获得健康行为改变方面的高级培训，以便她可以利用她在营养和运动生理学方面的背景，开发创新的长期，基于行为理论的体重增加预防干预措施。戴维博士的长期职业目标是开发一个独立的，成功的，课外资助的研究计划，重点是长期预防体重增加。为了实现这一目标，她建议获得几个领域的知识和技术专长：1）基于理论的健康行为改变的科学和实践，2）使用先进技术进行健康行为改变干预，3）饮食摄入和身体活动评估方法，4）统计和实验设计。Davy博士在该机构的可用资源以及她的指导团队（包括Donnelly博士、Hill博士、Most博士、菲利普斯博士、兰金博士和她的主要导师Winett博士）的综合经验，确保了拟议目标的实现。结构化的课程，研讨会和实地考察的培训计划与研究计划相结合，这将使戴维博士能够获得在她的职业发展目标中确定的知识和专业知识。该研究计划的重点是“缩小能量差距”（例如，与我们人群中体重平均增加相关的过量卡路里），以防止有体重增加风险的大学生体重增加。主要目的是确定一个长期的互联网提供的体重增加预防计划在大学生中的有效性。我们将采用基于社会认知理论（SCT）的互联网干预，通过促进饮食和体育活动习惯的微小但可持续的变化来“缩小能量差距”。我们还将确定该人群中预防体重增加的潜在介质的影响，包括膳食脂肪摄入量，水果/蔬菜消费量，体育活动习惯和与自我调节相关的行为。预防体重增加的方法可以为年轻人提供长期成功管理体重的技能。如果这种通过互联网提供的体重增加预防方法在这一高危人群中有效，那么可以对其进行修改，以覆盖其他人群中的更多个体。

DESCRIPTION (provided by applicant): The ability to comprehensively address research questions related to successful weight gain prevention requires knowledge of both physiological and behavioral aspects of weight regulation. The primary objective of this K01 Career Development Award is to enable Dr. Davy to obtain advanced training in health behavior change so that she may build upon her background in nutrition and exercise physiology to develop innovative long-term, behavioral theory-based weight gain prevention interventions. Dr. Davy's long-term career goal is to develop an independent, successful, extramurally-funded research program focused upon the long-term prevention of weight gain. To achieve this goal, she has proposed to acquire knowledge and technical expertise in several areas: 1) the science and practice of theory-based health behavior change, 2) the use of advanced technology for health behavior change interventions, 3) dietary intake and physical activity assessment methodologies, 4) statistics and experimental design. The resources available to Dr. Davy at this institution and the combined experience of her mentoring team, which includes Drs. Donnelly, Hill, Most, Phillips, Rankin, and her primary mentor, Dr. Winett, ensure the proposed objectives can be met. A training plan of structured coursework, workshops, and site visits is integrated with a research plan that will enable Dr. Davy to acquire the knowledge and expertise identifed in her career development objectives. The Research Plan is focused upon "closing the energy gap" (eg, excess calories associated with the mean increase in body weight in our population) to prevent weight gain in college students at-risk for weight gain. The primary aim is to determine the efficacy of a long-term Internet-delivered weight gain prevention program in college students. We will employ a social cognitive theory (SCT)-based Internet intervention to "close the energy gap" by promoting small but sustainable changes in diet and physical activity habits. We will also determine the influence of potential mediators of weight gain prevention in this population, including dietary fat intake, fruit/vegetable consumption, physical activity habits, and behaviors related to self-regulation. A weight gain prevention approach could provide young adults with the skills to successfully manage their weight long-term. If this Internet-delivered weight gain prevention approach is effective in this at-risk population, it could be modified to reach larger numbers of individuals in other populations.
