目的：研究健康老年人和年轻人在白天小睡、夜间睡眠和24小时睡眠/觉醒模式方面的差异。第二个目标是确定是否老年人与更多和更少的频繁午睡不同，在他们的临床特征或夜间sleep.Design：睡眠/唤醒日志和多导睡眠图调查。设置：睡眠/觉醒日志在受试者家中完成。多导睡眠图研究是在一个睡眠和时间生物学研究实验室的门诊基础上进行的。（21例男性，24例女性）和33例20 - 30岁的健康成人（20男，13女）。主要结果测量：使用自我报告，我们估计白天小睡的频率和时间;夜间睡眠的时间，持续时间和质量;以及24小时的睡眠和清醒模式。结果：与年轻人相比，老年受试者报告了更大的平均日间小睡次数（P = .004），更短的夜间睡眠，更多的觉醒和更早的睡眠时间（P < .003），以及更短的24小时睡眠分数的趋势。在老年人中，更频繁和更少的午睡者在临床评分，自我报告的睡眠测量或多导睡眠图测量方面没有差异。有一个趋势，更频繁nappers.Conclusions睡眠呼吸障碍和周期性肢体运动的昼夜节律睡眠倾向节律的振幅与年龄相关的下降，或与半昼夜（12小时）嗜睡节律的表达是一致的。然而，我们不能排除另一种可能性，即午睡是由生活方式因素和老年人夜间睡眠病理学引起的。
Objective: To examine differences between healthy elderly and young adults in daytime napping, nocturnal sleep, and 24-hour sleep/wake patterns. A second objective was to determine whether elderly subjects with more and less frequent naps differed in their clinical features or nocturnal sleep.Design: Survey by sleep/wake logs and polysomnography. Comparison by age.Setting: Sleep/wake logs were completed in the subjects' homes. Polysomnographic studies were conducted on an outpatient basis in a sleep and chronobiology research laboratory.Subjects: Convenience samples of forty-five healthy subjects over 78 years of age (21M, 24F) and 33 healthy adults between 20 and 30 years of age (20M, 13F).Main Outcome Measures: Using self-reports, we estimated the frequency and timing of daytime naps; timing, duration, and quality of nocturnal sleep; and 24-hour patterns of sleep and wakefulness. Also polysomnographic sleep measures.Results: Compared to young adults, elderly subjects reported a greater mean number of daytime naps (P = .004), shorter nocturnal sleep with more wakefulness and earlier sleep hours (P < .003 for each), and a trend for a shorter 24-hour sleep fraction. Among the elderly, more-frequent and less-frequent nappers did not differ in clinical ratings, self-report sleep measures, or polysomnographic measures. There was a trend for more sleep-disordered breathing and periodic limb movements in more frequent nappers.Conclusions: These findings are consistent with an age-related decrease in amplitude of the circadian sleep propensity rhythm, or with the expression of a semi-circadian (12-hour) sleepiness rhythm. However, we cannot exclude the additional possibility that napping results from lifestyle factors and nocturnal sleep pathologies in a subset of the elderly.
