Study Objective

Premenstrual dysphoric disorder (PMDD) is the most severe form for premenstrual distress. This study's objective was to understand the association among PMDD, premenstrual syndrome (PMS), and eating behaviors.

Design

Cross-sectional design. The survey was composed of validated measures.

Setting and Participants

Female students at a nursing school.

Main Outcome Measures

PMDD and PMS diagnoses were made using the Premenstrual Symptoms Screening Tool (PSST). Eating behaviors were assessed using the Eating Attitudes Test (EAT-26) and the Three-Factor Eating Questionnaire−Revised 18 (TFEQ-R18).

Results

Of the 504 participants, according to the PSST, 80 (15.9%) met the criteria for PMDD, 222 (44%) had moderate-to-severe PMS, and the remaining 202 (40%) participants showed mild or no premenstrual symptoms. The total EAT-26 scores were significantly higher in the PMDD group than in the other groups (P < .001). According to the cut-off value (20 points) of EAT-26, the total prevalence of disordered eating behaviors was also significantly higher in the PMDD group (45.5%) compared with the moderate-to-severe PMS group (16.5%) and the no/mild PMS group (13.6%) (P < .001). According to the TFEQ-R18 scores, significantly higher scores for emotional eating and uncontrolled eating were found in the PMDD group than in the other groups (P < .001 for each).

Conclusions

Given that PMDD is defined as a more severe form of PMS with more strict criteria, the findings in this study reflect that as the severity of premenstrual symptoms increase, disordered eating behaviors also increase. To the best of our knowledge, this is the first study to compare eating behaviors among PMDD, moderate-to-severe PMS, and no/mild PMS groups.

月经前烦躁障碍与护理学生进食行为的关联性：跨学科研究

研究目的

经前烦躁不安（PMDD）是经前不适的最严重形式。这项研究的目的是了解PMDD，经前综合症（PMS）和饮食行为之间的关系。

设计

横断面设计。该调查由经过验证的措施组成。

设置和参加者

女学生在一所护理学校。

主要观察指标

PMDD和PMS诊断是使用经前症状筛查工具（PSST）进行的。使用饮食态度测验（EAT-26）和三因素饮食问卷修订版18（TFEQ-R18）评估饮食行为。

结果

根据PSST，在504名参与者中，有80名（15.9％）符合PMDD的标准，其中222名（44％）患有中度至重度PMS，其余202名（40％）参与者表现出轻度或无经前症状。PMDD组的EAT-26总得分显着高于其他组（P  <.001）。根据EAT-26的临界值（20分），与中至重度PMS组（16.5％）相比，PMDD组（45.5％）的饮食失调行为总患病率也明显更高。无/轻度PMS组（13.6％）（P  <.001）。根据TFEQ-R18评分，与其他组相比，PMDD组的情感饮食和无节制饮食得分明显更高（每组P  <.001）。

结论

鉴于PMDD被定义为具有更严格标准的PMS的更严重形式，本研究的发现反映出，随着经前症状的严重程度增加，饮食失调行为也会增加。据我们所知，这是第一项比较PMDD，中至重度PMS和无/轻度PMS组进食行为的研究。
