When the electroencephalogram-recorded (EEG) sleep of 19 healthy seniors (9 men, 10 women) aged 60-82 years was restudied after an average interval of 2.2 years, most measures of EEG sleep and sleep quality were stable over time. Both elderly men and women showed more awakenings during the second recording series, but no change in visual or computer-scored delta activity. Furthermore, gender-dependent sleep changes were noted only in phasic rapid eye movement (REM) measures (increasing in men, decreasing in women). Reports of sleep quality were also stable over time despite the increase in awakenings, with women reporting a lower sleep quality than men.
在平均间隔2.2年后，对19名年龄在60 - 82岁的健康老年人（9名男性，10名女性）的脑电图记录（EEG）睡眠进行重新研究时，EEG睡眠和睡眠质量的大多数指标随时间保持稳定。老年男性和女性在第二次记录期间的觉醒次数均有所增加，但视觉或计算机评分的δ活动没有变化。此外，仅在相位性快速眼动（REM）指标中发现了性别依赖性睡眠变化（男性增加，女性减少）。尽管觉醒次数增加，但睡眠质量报告随时间也保持稳定，女性报告的睡眠质量低于男性。
