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.
项目摘要
饮食失调,包括认知(例如,对身体的不满,对苗条的渴望,专注
与减肥)和行为因素(例如,适得其反的行为,如泻药的使用,暴饮暴食,
呕吐以控制体重),由于其与代谢危险因素有关,特别有害。重量
耻辱已经成为饮食失调的一个危险因素,超过2亿美国人的体重
指数,使他们处于风险的经验重量耻辱。然而,文献中存在三大空白。
先前的工作已经通过以下方式研究了体重耻辱和饮食失调行为之间的关系:
观察和纵向的方法,因此,体重耻辱是否导致饮食失调是未知的。
此外,研究还没有检查饮食失调症状在日常生活中的存在,
暴露在体重的耻辱。最后,潜在的社会复原力因素仍未得到探索。因此目前
研究将结合联合收割机实验操作和每日日记方法来评价
对日常饮食失调症状和测试归属感和群体识别的重量耻辱作为社会
抵抗力因素,保护人们不受饮食失调的影响。该项目将利用
申办方Tomiyama母公司R01(R01HL158555)的基础设施,并将增加全面测量
在从洛杉矶招募的300名超重(BMI> 28)成年参与者中,
洛杉矶地区解决两个目标:1)评估体重耻辱对饮食失调的因果影响
2)调查社会弹性因素,提供保护,以防止疾病
进食症状本研究将有助于了解体重污名的影响,并确定弹性因素
防止饮食失调目前的提议可以帮助确定那些可能更脆弱的人
饮食失调作为体重耻辱的结果,或确定未来的干预策略,反过来,
促进新陈代谢健康。
在整个研究期间,在申办者Dr. A. Janet Tomiyama和合作者Dr.
克雷格恩德斯,西奥多罗伯斯,肯德林索内维尔,我将努力实现四个培训目标:1)
掌握先进的定量分析技能,特别是在多层次建模和增长曲线分析,2)
扩大饮食失调的知识,特别是在成年期,3)发展社会适应能力的专业知识
因素,和4)准备作为一个独立的研究人员的职业生涯。我将通过参加
参加实验室会议和研讨会,在学术会议上展示我的工作,
在课程上。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R1机构资助的研究人员,包括从事开放科学,执行循证医学,
指导实践,建立赠款写作技巧,并实践科学传播。
