中年和老年人在多导睡眠图（PSG）睡眠中表现出性别差异;然而，年轻男性和女性是否也表现出这种差异尚不清楚。31名年轻的健康睡眠者（16名男性和15名女性，年龄18至30岁，平均值± SD，20.5 ± 2.4岁）在进入研究前保持稳定的睡眠-觉醒周期1周后，在睡眠实验室完成了连续3个通宵的睡眠。每晚收集标准PSG睡眠和自我评定的嗜睡数据。在夜间，女性的睡眠质量比男性更好：她们入睡更快（睡眠开始潜伏期更短），睡眠效率更高，睡眠时间更多，醒着时间更少（所有差异均显示出较大的效应量，d = 0.98至1.12）。相比之下，男性在夜间比女性更困倦。与随后的两个晚上相比，男性和女性在第一个晚上的整体睡眠质量都较差。我们的结论是，年轻健康的成年人在PSG睡眠中表现出强烈的性别差异，就像老年人一样，女性的睡眠质量比男性好。这些结果强调了性别在睡眠和昼夜节律研究中的重要性，并对与这些主题相关的女性健康问题产生了更广泛的影响。
Middle-aged and elderly populations exhibit gender differences in polysomnographic (PSG) sleep; however, whether young men and women also show such differences remains unclear. Thirty-one young healthy sleepers (16 men and 15 women, aged 18 to 30 yr, mean +/- SD, 20.5 +/- 2.4 yr) completed 3 consecutive overnight sessions in a sleep laboratory, after maintaining a stable sleep-wake cycle for 1 wk before study entry. Standard PSG sleep and self-rated sleepiness data were collected each night. Across nights, women showed better sleep quality than men: they fell asleep faster (shorter sleep onset latency) and had better sleep efficiency, with more time asleep and less time awake (all differences showed large effect sizes, d = 0.98 to 1.12). By contrast, men were sleepier than women across nights. Both men and women demonstrated poorer overall sleep quality on the first night compared with the subsequent 2 nights of study. We conclude young adult healthy sleepers show robust gender differences in PSG sleep, like older populations, with better sleep quality in women than in men. These results highlight the importance of gender in sleep and circadian rhythm research studies employing young subjects and have broader implications for women's health issues relating to these topics.
