项目摘要

PROJECT SUMMARY Disordered eating, encompassing both cognitive (e.g. body dissatisfaction, drive for thinness, preoccupation with losing weight) and behavioral factors (e.g. counterproductive behaviors like laxative use, binge eating, and vomiting for weight control), is particularly harmful given its association with metabolic risk factors. Weight stigma has emerged as a risk factor for disordered eating, and over 200 million Americans have a body mass index that puts them at risk for experience weight stigma. However, there are three major gaps in the literature. Prior work has examined associations between weight stigma and disordered eating behaviors via observational and longitudinal methods, and thus whether weight stigma causes disordered eating is unknown. Moreover, research has not examined the presence of disordered eating symptoms in everyday life after exposure to weight stigma. Finally, potential social resilience factors remain unexplored. Therefore, the current study will combine experimental manipulation with daily diary methodology to evaluate the causal effect of weight stigma on daily disordered eating symptoms and test belonging and group identification as social resilience factors that confer protection against disordered eating. This project will capitalize on the infrastructure of Sponsor Tomiyama’s parent R01 (R01HL158555) and will add comprehensive measurement of disordered eating symptoms in 300 overweight (BMI  28) adult participants recruited from the greater Los Angeles area to address two aims: 1) Assess the causal effects of weight stigma on disordered eating symptoms in daily life and 2) Investigate social resilience factors that provide protection against disordered eating symptoms. This study will help to understand the impact of weight stigma and identify resilience factors to prevent disordered eating. The current proposal could aid in identifying those who may be more vulnerable to disordered eating as a consequence of weight stigma, or identify future intervention strategies, and in turn, promote metabolic health. Throughout the fellowship period, with the support of Sponsor Dr. A. Janet Tomiyama and Collaborators Drs. Craig Enders, Theodore Robles, and Kendrin Sonneville, I will be working to achieve four training aims: 1) Master advanced quantitative analysis skills, specifically in multilevel modeling and growth curve analysis, 2) Expand knowledge in disordered eating, specifically in adulthood, 3) Develop expertise in social resilience factors, and 4) Prepare for a career as an independent researcher. I will accomplish these goals by attending and participating in lab meetings and workshops, presenting my work at academic conferences, and enrolling in coursework. Further, I will be focusing on four subaims that will prepare me for a career as an extramurally funded researcher at an R1 institution, including engaging in open science, executing evidence-based practices in mentoring, building grant writing skills, and practicing scientific dissemination.

项目概要饮食失调，既有认知方面的（例如对身体的不满、对瘦身的渴望、全神贯注）减肥）和行为因素（例如适得其反的行为，如使用泻药、暴饮暴食和考虑到呕吐与体重风险因素的相关性，呕吐对于控制体重尤其有害。耻辱已成为饮食失调的一个危险因素，超过 2 亿美国人的体重然而，文献中存在三个主要空白。之前的工作已经通过以下方式研究了体重耻辱与饮食失调行为之间的关联：观察和纵向方法，因此体重耻辱是否导致饮食失调尚不清楚。此外，研究尚未检验术后日常生活中是否存在饮食失调症状。最后，潜在的社会弹性因素尚未得到探索。研究将实验操作与每日日记方法相结合，以评估因果效应体重耻辱对日常饮食失调症状的影响以及测试归属感和群体认同的社会性该项目将利用这一成果来防止饮食失调。赞助商富山母公司 R01 (R01HL158555) 的基础设施，并将添加综合测量从大洛杉矶地区招募的 300 名超重 (BMI ≥ 28) 成人参与者中饮食失调症状的情况安吉利斯地区致力于实现两个目标：1）评估体重耻辱对饮食失调的因果影响日常生活中的症状，以及 2) 调查可预防紊乱的社会复原力因素这项研究将有助于了解体重耻辱的影响并确定弹性因素。防止饮食失调，目前的提议可以帮助识别那些可能更容易受到伤害的人。因体重耻辱而导致的饮食失调，或确定未来的干预策略，反过来，促进代谢健康。在整个研究金期间，在赞助商 A. Janet Tomiyama 博士和合作者 Drs. 的支持下。 Craig Enders、Theodore Robles 和 Kendrin Sonneville，我将努力实现四个培训目标：1) 掌握高级定量分析技能，特别是多层次建模和增长曲线分析，2) 扩展有关饮食失调的知识，特别是在成年期，3) 发展社会复原力方面的专业知识因素，以及 4) 为独立研究员的职业生涯做准备我将通过参加来实现这些目标。参加实验室会议和研讨会，在学术会议上展示我的工作，并注册此外，在课程作业中，我将重点关注四个子目标，这将为我的校外职业生涯做好准备。资助 R1 机构的研究人员，包括从事开放科学、执行基于证据的研究指导、培养资助写作技巧和实践科学传播方面的实践。
