The effect of weight stigma on daily disordered eating and potential resilience factors

项目总结 饮食失调，包括认知(例如，身体不满意，追求苗条，全神贯注 减肥)和行为因素(例如，使用泻药、暴饮暴食等反生产行为，以及 呕吐以控制体重)，尤其有害，因为它与代谢风险因素有关。重量 耻辱已经成为饮食失调的一个危险因素，超过2亿美国人有体重 这一指数使他们面临体验体重污名的风险。然而，文献中有三个主要的空白。 先前的工作研究了体重歧视和饮食失调行为之间的关系，通过 观察法和纵向法，因此体重歧视是否会导致进食障碍尚不清楚。 此外，研究还没有检查日常生活中是否存在饮食失调症状 暴露在体重污名之下。最后，潜在的社会复原力因素仍未被发掘。因此，当前 研究将实验操作与日常日记方法学相结合，以评估 日常饮食失调症状的体重污名和测试归属感和群体认同感 弹性因素，提供对饮食紊乱的保护。这个项目将利用 赞助商富山母公司R01(R01HL158555)的基础设施，并将增加全面的测量 从大洛杉矶招募的300名超重(体重指数28)成年参与者的进食障碍症状 洛杉矶地区解决两个目标：1)评估体重污名对饮食紊乱的因果影响 日常生活中的症状和2)调查对混乱提供保护的社会复原力因素 进食症状。这项研究将有助于理解体重污名的影响，并确定弹性因素 以防止饮食紊乱。目前的提案可能有助于识别那些可能更脆弱的人 由于体重歧视而导致的饮食紊乱，或确定未来的干预策略，进而， 促进新陈代谢健康。 在整个奖学金期间，在赞助商A.Janet Tomiyama博士和合作者Dr. 克雷格·恩德斯、西奥多·罗伯斯和肯德林·桑内维尔，我将努力实现四个培训目标：1) 掌握高级定量分析技能，特别是在多水平建模和增长曲线分析方面，2) 扩大饮食失调方面的知识，特别是在成年阶段，3)发展社会适应能力方面的专业知识 因素，以及4)为独立研究人员的职业生涯做准备。我将通过参加以下活动实现这些目标 参加实验室会议和研讨会，在学术会议上展示我的工作，并报名参加 在功课上。此外，我将专注于四个子目标，这将为我的职业生涯做好准备。 在一家R1机构资助的研究人员，包括从事开放科学，执行循证 指导、培养基金撰写技巧和实践科学传播的实践。

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.
