Subjective and objective assessments of sleep may be discrepant due to sleep misperception and measurement effects, the latter of which may change the quality and quantity of a person's usual sleep. This study compared sleep times from polysomnography (PSG) with self-reports of habitual sleep and sleep estimated on the morning after a PSG in adults.
Total sleep time and sleep onset latency obtained from unattended home PSGs were compared to sleep times obtained from a questionnaire completed before the PSG and a Morning Survey completed the morning after the PSG.
A total of 2,113 subjects who were > or = 40 years of age were included in this analysis.
Subjects were 53% female, 75% Caucasian, and 38% obese. The mean habitual sleep time (HABTST), morning estimated sleep time (AMTST), and PSG total sleep times (PSGTST) were 422 min, 379 min, and 363 min, respectively. The mean habitual sleep onset latency, morning estimated sleep onset latency, and PSG sleep onset latency were 17.0 min, 21.8 min, and 16.9 min, respectively. Models adjusting for related demographic factors showed that HABTST and AMTST differ significantly from PSGTST by 61 and 18 minutes, respectively. Obese and higher educated people reported less sleep time than their counterparts. Similarly, small but significant differences were seen for sleep latency.
In a community population, self-reported total sleep times and sleep latencies are overestimated even on the morning following overnight PSG.
由于睡眠感知错误和测量效应，睡眠的主观和客观评估可能存在差异，后者可能会改变一个人通常的睡眠质量和时长。本研究比较了多导睡眠图（PSG）记录的睡眠时间与成年人习惯性睡眠的自我报告以及PSG检查后早晨估计的睡眠时间。
将无人值守的家庭PSG记录的总睡眠时间和入睡潜伏期与PSG检查前完成的问卷以及PSG检查后早晨完成的早晨调查所获得的睡眠时间进行比较。
本分析共纳入了2113名年龄≥40岁的受试者。
受试者中53%为女性，75%为白种人，38%为肥胖者。习惯性平均睡眠时间（HABTST）、早晨估计睡眠时间（AMTST）和PSG总睡眠时间（PSGTST）分别为422分钟、379分钟和363分钟。习惯性平均入睡潜伏期、早晨估计入睡潜伏期和PSG入睡潜伏期分别为17.0分钟、21.8分钟和16.9分钟。调整相关人口统计学因素的模型显示，HABTST和AMTST与PSGTST分别有显著差异，相差61分钟和18分钟。肥胖者和受教育程度较高者报告的睡眠时间比其他人少。同样，入睡潜伏期也存在虽小但显著的差异。
在社区人群中，即使在夜间PSG检查后的早晨，自我报告的总睡眠时间和入睡潜伏期也被高估了。
