虽然自我报告的长时间睡眠与发病率和死亡率增加有关，但对长睡眠者的客观睡眠模式和日间功能知之甚少，特别是那些年龄≥50岁的人。我们的主要目的是比较客观和主观睡眠模式的样本（n = 35）的中老年成人谁报告睡眠≥8.5小时每晚。第二个目的是描述样本的情绪和功能。在2周的时间内，通过活动记录仪和每日日记记录睡眠。每天评估嗜睡。在2周结束时，评估日间嗜睡、情绪和生活质量。睡眠和功能的测量与现有的代表性数据进行了比较。在样本中，活动记录总睡眠时间（TST; 7.35 ± 0.97 h）比年龄相关的代表性值大约多60 min，但显著低于日记评估的TST（8.59 ± 0.74 h）和调查评估的TST（8.92 ± 0.78 h）。与TST相比，基于调查和日记的主观TST评估与活动记录的卧床时间（TIB; 9.11 ± 0.72 h）更接近，主观TST与活动记录的TIB之间的相关性与主观和活动记录的TST之间的相关性相似。情绪、嗜睡和日间功能的测量值与人群代表值相似。这些结果表明，在中老年人中，自我报告的长时间睡眠主要是长TIB的指示，但它也代表了长的客观睡眠持续时间，特别是与年龄匹配的数据相比。小功能障碍的调查结果证实了以前的描述老年长睡眠者。
Although self-reported long sleep is associated with increased morbidity and mortality, little is known about the objective sleep patterns and daytime functioning of long sleepers, particularly those aged ≥50 years. Our primary aim was to compare the objective and subjective sleep patterns of a sample (n = 35) of middle- to older-aged adults who reported sleeping ≥8.5 h per night. A secondary aim was to characterize the mood and functioning of the sample. Over a 2-week period, sleep was recorded via actigraphy and a daily diary. Sleepiness was assessed daily. At the conclusion of the 2-week period, daytime sleepiness, mood, and quality of life were assessed. Measures of sleep and functioning were compared with available representative data. In the sample, actigraphic total sleep time (TST; 7.35 ± 0.97 h) was approximately 60 min greater than age-related representative values but substantially less than diary-assessed TST (8.59 ± 0.74 h) and survey-assessed TST (8.92 ± 0.78 h). Survey and diary-based subjective TST assessments agreed more closely with actigraphic time in bed (TIB; 9.11 ± 0.72 h) than TST, and correlations between subjective TST and actigraphic TIB were similar to those between subjective and actigraphic TST. Measures of mood, sleepiness, and daytime functioning were similar to population-representative values. These results suggest that, among middle- to older-aged adults, self-reported long sleep is primarily indicative of long TIB, but it also represents long objective sleep duration, particularly in comparison to age-matched data. Findings of little functional impairment corroborated previous descriptions of older long sleepers.
