项目摘要
DESCRIPTION (provided by applicant): Dr. Unick is an Assistant Professor (Research) at the Warren Alpert Medical School at Brown University and an exercise physiologist at The Miriam Hospital's Weight Control and Diabetes Research Center. She received her PhD in exercise physiology from the University of Pittsburgh, where she also gained valuable experience in behavioral weight loss treatment. Her long-term goal is to become an independent exercise/obesity investigator, with a line of research focused on understanding the psychological factors through which exercise may assist in long-term weight control. The current application would add to the scant literature in this area by examining whether exercise reduces stress-induced overeating. An understanding of the basic mechanisms through which exercise influences weight control, is important for the future of obesity treatment. As part of this Mentored Research Scientist Development Award (K01), Dr. Unick will gain extensive training in the areas of (1) stress responses and stress methodology, (2) stress as it specifically affects obesity, (3) the psychological benefits of exercise as observed in the treatment of addictions, (4)
ecological momentary assessment (EMA) and statistical analyses, (5) the responsible conduct of research, and (6) professional development focused on becoming an independent investigator. This training will occur in the form of didactics and hands-on experiences gained under the guidance and supervision of a highly qualified team of mentors. Dr. Unick will work closely with her primary mentor, Dr. Rena Wing, an internationally recognized obesity researcher, as well as her multidisciplinary team of co-mentors [Dr. Laura Stroud (stress methodology), Dr. Elissa Epel (stress and obesity), Dr. Rick Brown (exercise in addictions), and Drs. Ross Crosby and Graham Thomas (EMA and statistical analyses)]. The research will be conducted at The Miriam Hospital & Brown Medical School, an environment well-suited for developing junior investigators and fully equipped with the resources to carry out the proposed research plan. Given that stress contributes to overeating and poor dietary choices and a separate body of literature demonstrating that exercise reduces stress, the current application seeks to examine the novel question of whether exercise training reduces stress-induced eating. We will begin by examining this in a tightly controlled laboratory setting (Study 1) and then transition to the examination of this research question in a free-living environment (Study 2). In Study 1, 48 sedentary and overweight/obese women will be randomized to a 10- week supervised exercise training program (EX) or a no-exercise control condition (CON). Participants will come to the lab on two separate occasions at both baseline and 10 weeks. On one day they will be exposed to a psychosocial stressor while the other day will serve as a no-stress, control day. "Stress-induced eating" will be defined as the energy intake (measured via a buffet meal) following exposure to the stressor on the stress day minus the energy intake on the no-stress day. It is hypothesized that EX will reduce "stress-induced eating" relative to CON. Given that exposure to a psychosocial stressor and buffet meal in a laboratory setting may not mimic real world conditions, Study 2 will focus on whether exercise reduces stress-induced overeating using smart phones and EMA data collection methods, designed to obtain 'real-time' responses in a free living environment. Forty-eight sedentary, overweight/obese women will be randomized to 10 weeks of supervised exercise training (EX) or a no-exercise control condition (CON). Participants will be asked to log their stress, mood, hunger, dietary temptations/lapses, and "overeating" episodes via a smart phone for 10 days before and after the training period. It is hypothesized that EX will reduce the proportion of "overeating" and "stress-induced overeating" episodes, relative to CON. The proposed studies are the first to examine the effects of exercise training on stress-induced overeating, addressing an important research gap in the area of exercise and obesity. The rigorous methodology, randomized design, and novel use of dual methodologies (lab to life generalization) make this application both significant and innovative. Moreover, these studies will provide rich data sets, enabling Dr. Unick to conduct additional exploratory and hypothesis generating analyses, which will also help facilitate her transition to an independent investigator. It is expected that through the formal coursework, hands-on training, and excellent mentorship, Dr. Unick will gain the knowledge and skills necessary to develop an independent, extramurally funded research career in the area of exercise and obesity.
描述(由申请人提供):Unick 博士是布朗大学沃伦阿尔珀特医学院的助理教授(研究),也是米里亚姆医院体重控制和糖尿病研究中心的运动生理学家。她在匹兹堡大学获得运动生理学博士学位,并在行为减肥治疗方面获得了宝贵的经验。她的长期目标是成为一名独立的运动/肥胖调查员,其一系列研究重点是了解运动可能有助于长期体重控制的心理因素。目前的应用程序将通过检查运动是否可以减少压力引起的暴饮暴食来补充该领域的稀缺文献。了解运动影响体重控制的基本机制对于肥胖治疗的未来非常重要。作为指导研究科学家发展奖 (K01) 的一部分,Unick 博士将获得以下领域的广泛培训:(1) 压力反应和压力方法,(2) 压力,因为它特别影响肥胖,(3) 压力的心理益处在成瘾治疗中观察到的锻炼,(4)
生态瞬时评估(EMA)和统计分析,(5)负责任的研究行为,以及(6)专注于成为独立研究者的专业发展。该培训将以在高素质导师团队的指导和监督下获得的教学和实践经验的形式进行。 Unick 博士将与她的主要导师 Rena Wing 博士(国际公认的肥胖研究人员)以及她的多学科合作导师团队密切合作 [Dr. Unick]。 Laura Stroud(压力方法)、Elissa Epel 博士(压力和肥胖)、Rick Brown 博士(成瘾运动)和 Drs. Ross Crosby 和 Graham Thomas(EMA 和统计分析)]。该研究将在米里亚姆医院和布朗医学院进行,该环境非常适合培养初级研究人员,并完全配备了实施拟议研究计划的资源。鉴于压力会导致暴饮暴食和不良饮食选择,并且有大量文献证明运动可以减轻压力,本申请旨在研究运动训练是否可以减少压力引起的饮食这一新问题。我们将首先在严格控制的实验室环境中检查这一问题(研究 1),然后过渡到在自由生活环境中检查该研究问题(研究 2)。在研究 1 中,48 名久坐和超重/肥胖的女性将被随机分配接受为期 10 周的监督运动训练计划 (EX) 或无运动控制条件 (CON)。参与者将在基线和 10 周期间两次来到实验室。有一天,他们将面临社会心理压力,而另一天将成为无压力的控制日。 “压力引起的饮食”将被定义为在压力日暴露于压力源后的能量摄入量(通过自助餐测量)减去无压力日的能量摄入量。据推测,相对于 CON,EX 会减少“压力诱发的饮食”。鉴于在实验室环境中暴露于社会心理压力源和自助餐可能无法模拟现实世界的情况,研究 2 将重点研究运动是否可以使用智能手机和 EMA 数据收集方法来减少压力引起的暴饮暴食,这些数据收集方法旨在获得“实时”数据在自由的生活环境中做出反应。 48 名久坐、超重/肥胖的女性将被随机分配接受 10 周的监督运动训练 (EX) 或无运动控制条件 (CON)。参与者将被要求在训练前后 10 天内通过智能手机记录他们的压力、情绪、饥饿、饮食诱惑/失误以及“暴饮暴食”事件。据推测,相对于 CON,EX 将减少“暴饮暴食”和“压力诱发的暴饮暴食”事件的比例。拟议的研究首次探讨了运动训练对压力引起的暴饮暴食的影响,填补了运动和肥胖领域的一个重要研究空白。严格的方法、随机设计和双重方法(实验室到生活的推广)的新颖使用使该应用既具有重要意义又具有创新性。此外,这些研究将提供丰富的数据集,使 Unick 博士能够进行额外的探索性和假设生成分析,这也将有助于促进她向独立研究者的过渡。预计通过正式课程、实践培训和出色的指导,尤尼克博士将获得在运动和肥胖领域发展独立的、校外资助的研究职业所需的知识和技能。
