A Laboratory Study of Adolescents' Eating in the Absence of Hunger

描述（由申请人提供）：获得该博士后奖学金将有助于申请人成为青少年健康和发展领域富有成效的独立研究者的长期目标。Lauren Shomaker博士对社会能力和理解饮食失调的发展以及共病的社会情绪和行为问题特别感兴趣。拟议的培训计划将使她在儿童饮食失调及其与肥胖的重叠方面获得进一步的专业知识，并获得用于研究这些问题的先进方法的技能。这些目标将在USUHS和NIH丰富的培训环境中完成，并通过在进食障碍和儿童肥胖领域具有专业知识的两位共同赞助者(Marian Tanofsky-Kraff博士，Jack A。Yanovski博士)。Shomaker博士组建了一支强大的顾问团队，他们在肥胖治疗（Nazrat Mirza，医学博士，理学博士）、不饥饿饮食（Myles Faith，博士）、饮食失调（J. Kevin Thompson，博士）和营养（Nancy Sebring，医学博士，RD）方面拥有丰富的专业知识。儿童超重作为一个重大的公共卫生问题已经得到越来越多的认可，它带来了惊人的个人、社会和医疗成本。体重过重的青少年在当前和未来出现身体健康问题的风险增加(例如：

DESCRIPTION (provided by applicant): Receipt of this postdoctoral fellowship award would facilitate the applicant's long-term objective to become a productive, independent investigator in the area of adolescent health and development. Lauren Shomaker, PhD has particular interests in social competence and understanding development of disordered eating and co-morbid socio-emotional and behavioral problems. The proposed training plan will enable her to obtain further expertise in pediatric disordered eating and its overlap with obesity, and acquire advanced skills in the methodologies used to study these problems. These goals will be accomplished in the rich training environments of USUHS and NIH, and through research mentorship with two co-sponsors with expertise in the fields of disturbed eating and pediatric obesity (Marian Tanofsky-Kraff, PhD, Jack A . Yanovski, MD, PhD). Dr. Shomaker has put together a strong team of consultants with expertise in diversity in obesity treatment (Nazrat Mirza, MD, ScD), eating in the absence of hunger ( Myles Faith, PhD), eating disorders (J. Kevin Thompson, PhD), and nutrition (Nancy Sebring, MEd, RD). Pediatric overweight has gained increasing recognition as a major public health concern with striking personal, societal, and healthcare costs. Overweight youth are at increased risk for immediate and future physical health problems (e.g., diabetes) and socio-emotional difficulties (e.g., depression). Identification of eating behaviors such as eating in the absence of hunger and disordered eating associated with risk for obesity onset is critical for designing effective interventions. In the proposed project, Dr. Shomaker employs a laboratory design to examine whether eating in the absence of hunger is associated with weight status in adolescence. Participants will be 120 adolescents from a racially and ethnically diverse community sample. Adolescents' caloric intake will be observed during two successive test meals. Adolescents first will eat until they are full and are then presented with access to a different array of highly palatable snack foods. The primary hypothesis is that overweight adolescents will eat more during the second meal (eating in the absence of hunger) than their non-overweight counterparts. The study also aims to examine links between eating in the absence of hunger and disordered eating as assessed by interview and questionnaires. PUBLIC HEALTH RELEVANCE: Additionally, using SEM, a provisional theoretical model of proposed relations among interpersonal interactions, body image, negative affect, depressive symptoms, disordered eating, eating in the absence of hunger, and adolescent overweight will be examined. Such an investigation is a crucial step in facilitating the formation of accurate, integrated models of the temporal sequence of eating behaviors that lead to future obesity and disordered eating.
