A cross-sectional study investigated relationships among premenstrual syndrome (PMS), negative perceived stress, and emotional eating in 409 women. Participants completed three questionnaires and were grouped into PMDD and non-PMDD cohorts. The PMDD group had significantly higher scores for emotional eating, PMS, and negative perceived stress than the non-PMDD group, with no difference in BMI. Mediation analyses showed that in the non-PMDD group, only negative perceived stress had a significant effect on emotional eating. In the PMDD group, PMS had a significant effect on both negative perceived stress and emotional eating, with negative perceived stress acting as a partial or complete mediator. The study suggests managing negative perceived stress may help control emotional eating in women with PMS/PMDD.

ABSTRACT

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 2 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 t -tests and mediation analyses were performed to compare the 2 groups. RESULTS 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. CONCLUSIONS This study highlights the importance of managing negative perceived stress to control emotional eating in PMS/PMDD for improved women’s health.
