Female athletes with menstrual abnormalities have poor sleep quality. However, whether female athletes with poor sleep quality based on subjective assessment have distinctive changes in objective measures of sleep in association with menses remains unclear. This study aimed to compare changes in objective sleep measurements during and following menses between collegiate female athletes with and without poor subjective sleep quality.
Female collegiate athletes (age range/mean ± standard deviation: 18-22/ 22.2±1.1) with regular menstrual cycles were recruited. The participants underwent home electroencephalogram monitoring during the first and second nights after the onset of menses and one night between the seventh and 10th nights after menses onset (mid-follicular phase). The Pittsburgh Sleep Quality Index (PSQI) was used to assess the subjective sleep quality. Interactions between the presence of poor subjective sleep quality (ie, PSQI ≥6) and changes in objective measures of sleep in association with menses were analyzed.
Data of 45 athletes, including 13 with poor subjective sleep quality, showed that changes in arousal index in athletes with poor subjective sleep quality were distinctive from those in athletes without poor subjective sleep quality (p = 0.036 for interaction). In athletes with poor subjective sleep quality, the arousal index was significantly increased in menses (p for analysis of variance, 0.015), especially on the first night after the onset of menses compared with during the mid-follicular phase (p = 0.016).
Collegiate female athletes with regular menstrual cycles are likely to have poor subjective sleep quality in association with more frequent arousal during the first night after the onset of menses than during the mid-follicular phase.
月经异常的女运动员睡眠质量较差。然而，基于主观评估睡眠质量差的女运动员在与月经相关的客观睡眠指标上是否有明显变化仍不清楚。本研究旨在比较主观睡眠质量差和不差的大学女运动员在月经期间及月经后客观睡眠指标的变化。
招募月经周期规律的大学女运动员（年龄范围/平均±标准差：18 - 22/22.2±1.1）。参与者在月经开始后的第一晚和第二晚以及月经开始后第七至第十晚之间的一个晚上（卵泡中期）进行家庭脑电图监测。匹兹堡睡眠质量指数（PSQI）用于评估主观睡眠质量。分析主观睡眠质量差（即PSQI≥6）与月经相关的客观睡眠指标变化之间的相互作用。
45名运动员的数据，包括13名主观睡眠质量差的运动员，显示主观睡眠质量差的运动员的觉醒指数变化与主观睡眠质量不差的运动员不同（交互作用p = 0.036）。在主观睡眠质量差的运动员中，月经期间觉醒指数显著增加（方差分析p = 0.015），尤其是月经开始后的第一晚与卵泡中期相比（p = 0.016）。
月经周期规律的大学女运动员在月经开始后的第一晚比卵泡中期更容易出现主观睡眠质量差且觉醒更频繁的情况。
