BACKGROUND/OBJECTIVES: Emotional eating is one of the eating behaviors in which negative emotions affect eating. During the luteal phase, premenstrual syndrome (PMS) and its associated psychological and physical symptoms can appear in some women, and a few of them suffer from premenstrual dysphoric disorder (PMDD), a severe form of PMS. Some women diagnosed with PMS/PMDD experience emotional eating during the luteal phase, which may be a coping mechanism for psychological stress. This study aimed to investigate how PMS/PMDD and negatively perceived stress are related to emotional eating.
SUBJECTS/METHODS: A total of 409 women aged 20 to 39 yrs with a body mass index (BMI) ranging from 18.5 to 29.9 kg/m participated in this study. Participants who responded to all the questions of the Shortened Premenstrual Assessment Form, Negative Perceived Stress Scale, and Emotional Eater Questionnaire were divided into a PMDD and a non-PMDD group according to the cut-off value for PMDD diagnosis. Independent -tests and mediation analyses were performed to compare the 2 groups.
No significant differences between the 2 groups were found in terms of BMI; however, the average values for emotional eating, PMS, and negative perceived stress of the PMDD group were significantly higher than those of the non-PMDD group. Only negative perceived stress had a significant effect on emotional eating in the non-PMDD group. In the PMDD group, PMS was statistically significant for both negative perceived stress and emotional eating mediated by negative perceived stress. Consequently, it appeared to have a partial or complete mediation depending on the independent variable for the PMDD group.
This study highlights the importance of managing negative perceived stress to control emotional eating in PMS/PMDD for improved women's health.
背景/目的：情绪化进食是一种负面情绪影响进食的饮食行为。在黄体期，一些女性会出现经前综合征（PMS）及其相关的心理和生理症状，其中少数人患有经前烦躁障碍（PMDD），这是PMS的一种严重形式。一些被诊断为PMS/PMDD的女性在黄体期会出现情绪化进食，这可能是应对心理压力的一种机制。本研究旨在调查PMS/PMDD和负面感知压力与情绪化进食之间的关系。
受试者/方法：共有409名年龄在20至39岁之间、体重指数（BMI）在18.5至29.9kg/m之间的女性参与了本研究。根据PMDD诊断的临界值，将对简化经前评估表、负面感知压力量表和情绪化进食问卷所有问题都做出回答的参与者分为PMDD组和非PMDD组。进行独立样本t检验和中介分析以比较两组。
两组在BMI方面未发现显著差异；然而，PMDD组的情绪化进食、PMS和负面感知压力的平均值显著高于非PMDD组。在非PMDD组中，只有负面感知压力对情绪化进食有显著影响。在PMDD组中，PMS对负面感知压力以及由负面感知压力介导的情绪化进食均具有统计学意义。因此，根据PMDD组的自变量，它似乎具有部分或完全中介作用。
本研究强调了管理负面感知压力对于控制PMS/PMDD中的情绪化进食以改善女性健康状况至关重要。
