We examined changes in drive for thinness, body dissatisfaction, and dietary restraint across the menstrual cycle and associations between these symptoms and ovarian hormones in two independent samples of women (N = 10 and 8 women, respectively) drawn from the community.
Daily self-report measures of disordered eating and negative affect were completed for 35-65 days. Daily saliva samples were assayed for estradiol and progesterone in Study 2 only.
Levels of body dissatisfaction and drive for thinness were highest during the mid-luteal/pre-menstrual phases in both studies and were negatively associated with estradiol, and positively associated with progesterone. By contrast, dietary restraint showed less variation across the menstrual cycle and weaker associations with ovarian hormones.
Differential associations between ovarian hormones and specific disordered eating symptoms point to distinct etiological processes within the broader construct of disordered eating.
我们在两个独立的社区女性样本（分别为 10 名和 8 名女性）中，研究了经前期和月经期周期中对苗条的渴望、身体不满和饮食限制的变化，以及这些症状与卵巢激素之间的关联。
对饮食失调和负性情绪进行了 35-65 天的日常自我报告测量。仅在研究 2 中，每日唾液样本检测雌二醇和孕酮。
在两个研究中，身体不满和对苗条的渴望程度在中期黄体期/经前期最高，与雌二醇呈负相关，与孕酮呈正相关。相比之下，饮食限制在月经周期中变化较小，与卵巢激素的关联也较弱。
卵巢激素与特定饮食失调症状之间的差异关联表明，在饮食失调这一广泛的概念中存在不同的病因机制。
