Abstract

Introduction: The current study used ecological momentary assessment (EMA) to examine whether body mass index (BMI) and weight suppression (highest minus current weight) predicted momentary body dissatisfaction and disordered eating urges, including dietary restriction, excessive exercise, binge eating, and unhealthy eating, and whether trait eating disorder (ED) symptoms moderated these associations.

Method: Data were collected from 686 adults (75% female), comprising community participants and undergraduate students, through six daily EMA surveys over seven days (42 possible assessments).

Results: Multilevel models showed that lower BMI (p = 0.005) and greater weight suppression (p = 0.004) predicted higher average state body dissatisfaction, while higher BMI (p < 0.001) and greater weight suppression (p = 0.039) predicted stronger urges for unhealthy eating.

Discussion: ED symptomatology moderated the relationship between BMI and dietary restraint, such that BMI positively predicted restraint urges at low levels of ED symptoms but negatively predicted them at high levels. No other moderating effects of ED symptomatology were observed for BMI or weight suppression on the remaining state-based outcomes. Overall, both weight-based severity indicators (BMI and weight suppression) demonstrated limited utility for indexing ED-related state-based variables in a female non-clinical sample. Future studies should examine additional weight-related severity indicators across both non-clinical and clinical ED samples.

体重抑制和体重指数能预测非临床成年人的日常身体形象和饮食冲动吗？

本研究使用生态瞬时评估（EMA）来检查体重指数（BMI）和体重抑制（最高减去当前体重）是否预测瞬时身体不满和饮食失调冲动，包括饮食限制、过度运动、暴饮暴食和不健康饮食，以及特质性饮食失调（ED）症状是否缓解了这些关联。方法：通过为期7天的每日6次EMA调查（42种可能的评估），从686名成年人（75%为女性）中收集数据，包括社区参与者和本科生。结果：多水平模型显示，较低的BMI （p = 0.005）和较强的体重抑制（p = 0.004）预示着较高的平均状态身体不满意度，而较高的BMI (p)。讨论：ED症状学调节了BMI与饮食限制之间的关系，即BMI在ED症状低水平时正预测约束冲动，而在ED症状高水平时负预测约束冲动。未观察到其他ED症状对BMI或体重抑制对剩余状态结果的调节作用。总体而言，在女性非临床样本中，基于体重的严重程度指标（BMI和体重抑制）在索引ed相关状态变量方面的效用有限。未来的研究应该在非临床和临床ED样本中检查更多与体重相关的严重程度指标。

期刊介绍： European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
