The present study aimed to determine whether the momentary severity of women's somatic symptoms was concurrently and prospectively associated with their engagement in binge eating in naturalistic settings.
Thirty women (M = 34.13, SD = 13.92) who had engaged in binge eating at least once over the month prior to study entry completed a 14-day ecological momentary assessment (EMA) protocol. During each of the 14 days, participants received five semi-random surveys via text message that assessed momentary somatic symptom severity (i.e., headaches, stomachaches/pain, chest/heart pain, faintness/dizziness, shortness of breath, fatigue) and disordered eating behaviors. Generalized estimating equations were used to determine whether momentary somatic symptoms were concurrently and prospectively (i.e., by participants' next assessment) associated with the occurrence of binge eating behavior, while controlling for age and body mass index.
At the within-person level, more severe stomachaches/pain, faintness/dizziness, shortness of breath, and fatigue were concurrently associated with an increased likelihood of engaging in binge eating. Further, at the between-person level, more severe stomachaches/pain, chest/heart pain, shortness of breath, and fatigue in general were associated with binge eating across the EMA protocol. Momentary stomachache/pain severity also prospectively predicted women's engagement in binge eating behavior at the next assessment.
The present results provide initial evidence that multiple somatic symptoms may serve as momentary correlates or proximal antecedents of binge eating behavior in women's daily lives. Somatic symptoms may consequently prove useful to target in eating disorder treatments, perhaps via interoceptive exposure interventions.
本研究旨在确定女性躯体症状的即时严重程度是否与她们在自然环境中暴食的参与度具有同时性和前瞻性关联。
30 名女性（M=34.13，SD=13.92）在研究入组前至少有一次暴食行为，她们完成了为期 14 天的生态瞬间评估（EMA）方案。在 14 天中的每一天，参与者都会通过短信收到五次半随机调查，评估即时躯体症状严重程度（即头痛、胃痛/疼痛、胸痛/心痛、晕厥/头晕、呼吸急促、疲劳）和饮食障碍行为。广义估计方程用于确定即时躯体症状是否与暴食行为的发生具有同时性和前瞻性（即通过参与者的下一次评估）关联，同时控制年龄和体重指数。
在个体内水平上，更严重的胃痛/疼痛、晕厥/头晕、呼吸急促和疲劳与暴食行为的发生几率增加具有同时相关性。此外，在个体间水平上，一般来说，更严重的胃痛/疼痛、胸痛/心痛、呼吸急促和疲劳与 EMA 方案中的暴食行为相关。即时胃痛/疼痛严重程度也可预测女性在下一次评估时参与暴食行为。
本研究结果初步表明，多种躯体症状可能是女性日常生活中暴食行为的即时相关因素或近期前因。因此，躯体症状可能在饮食障碍治疗中具有潜在的应用价值，例如通过内感受暴露干预。
