Sleep quality in university students with Premenstrual Dysphoric Disorder

BACKGROUND: Up to 8% of women in their reproductive years are affected by Premenstral Dysphoric Disorder (PMDD). Sleep disturbances such as insomnia or hypersomnia are one of the DSM-IV-TR's defining criteria for the diagnosis of PMDD and are found in about 70% of women with the disorder. However, studies are lacking that specifically address the effects of PMDD on quality of sleep. 目标: 本研究旨在评估女大学生中PMDD 的患病率及 其对睡眠质量的影响。. METHODS: We developed an 18-item PMDD scale based on The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) to diagnose PMDD in female university studentswho ranged in age from 18 to 30 years and had regular menstrual cycles.Participants were categorized into a PMDD group or a No/PMDD group and sleep quality was compared between the two groups. The evaluation tool used to measure sleep quality was the Pittsburgh Sleep Quality Index (PSQI). 结果: 女大学生PMDD 的患病率为25.5%。PSQI 分析 表明PMDD 组中80.5% 的女大学生PSQI 得分＞ 5， 而非 PMDD 组中相应的比例只有56.4%（χ2=12.459, p<0.001）。PMDD 组PSQI 平均分（标准差）为8.2 (3.4) 而非PMDD 组为6.5 (3.1)（t=3.648, p<0.001）。. CONCLUSIONS: Female university students who experience PMDD are deeply affected by sleep problems. Lower sleep quality, daytime dysfunction, and sleep disturbance are common sleep problems among female university students with PMDD. 关键词: 经前期烦躁障碍；睡眠质量；匹兹堡睡眠质 量指数；女大学生.
