Abstract

OBJECTIVE

Associations between within-person changes in ovarian hormones and dysregulated eating (binge eating, emotional eating) have been observed across the menstrual cycle. However, studies have not examined moderators that may contribute to differential associations between individuals. We investigated body-weight regulation variables [body mass index (BMI), dietary restraint] that have theoretical relevance by virtue of their associations with both phenotypes.

METHOD

Women (N = 196) provided emotional eating ratings and saliva samples for 45 days. BMI and restraint were assessed at three time points and averaged.

RESULTS

Results showed significant estradiol × progesterone interactions in the prediction of within-subject changes in emotional eating. Neither BMI nor restraint moderated these relationships, although a trend-level dietary restraint × estradiol interaction was observed where estradiol's effects were enhanced in high restraint scorers.

DISCUSSION

Findings confirm a role for hormones in changes in emotional eating and suggest that restraint might enhance hormone effects in severegroups.

摘要

目的

在整个月经周期中,观察到个体内卵巢激素变化与饮食失调(暴食、情绪性进食)之间存在关联。然而,研究尚未探讨可能导致个体之间关联存在差异的调节因素。我们研究了体重调节变量[体重指数(BMI)、饮食抑制],这些变量与两种表型都有关联,因此具有理论意义。

方法

196 名女性提供了 45 天的情绪性进食评分和唾液样本。BMI 和抑制在三个时间点进行评估并取平均值。

结果

结果显示,在预测情绪性进食的个体内变化时,雌二醇和孕酮存在显著的交互作用。BMI 和抑制都没有调节这些关系,但观察到饮食抑制和雌二醇之间存在趋势水平的交互作用,即高抑制得分者的雌二醇作用增强。

讨论

研究结果证实了激素在情绪性进食变化中的作用,并表明抑制可能会增强严重组激素的作用。
