Study Objectives:

Persons > 65 years with short sleep duration (≤ 6 hours) are at risk for adverse outcomes, but the accuracy of self-reported sleep duration may be affected by reduced symptom awareness. We evaluated the performance characteristics of self-reported versus objectively-measured sleep duration in this age group.

Methods:

In 2,980 men from the Osteoporotic Fractures in Men Sleep Study (MrOS) and 2,855 women from the Study of Osteoporotic Fractures (SOF), we examined the agreement and accuracy of self-reported versus actigraphy-measured short and normal (> 6 but < 9 hours) sleep duration. We evaluated associations of select factors (demographics, medical, physical, and neuropsychiatric conditions, medication and substance use, and sleep-related measures) with risk of false-negative (normal sleep duration by self-report but short sleep duration by actigraphy) and false-positive (short sleep duration by self-report and normal sleep duration by actigraphy) designations, respectively, using logistic regression.

Results:

Average ages were 76.3 ± 5.5 and 83.5 ± 3.7 years in men and women, respectively. There was poor agreement between self-reported and actigraphic sleep duration (Kappa ≤ 0.24). False-negatives occurred in nearly half and false-positives in over a quarter of older persons. In multivariable models in men and women, false-negatives were independently associated with obesity, daytime sleepiness, and napping, while false-positives were significantly lower with obesity.

Conclusions:

Under- and over-reporting of short sleep is common among older persons. Reliance on self-report may lead to missed opportunities to prevent adverse outcomes or unnecessary interventions. Self-reported sleep duration should be objectively confirmed when evaluating the effect of sleep duration on health outcomes.

老年人自我报告和活动性睡眠时间短

学习目标：

65 岁以上睡眠时间短（≤ 6 小时）的人有出现不良后果的风险，但自我报告睡眠时间的准确性可能会受到症状意识降低的影响。我们评估了该年龄组自我报告与客观测量的睡眠持续时间的表现特征。

方法：

在来自男性睡眠研究 (MrOS) 的骨质疏松性骨折 (MrOS) 的 2,980 名男性和来自骨质疏松性骨折研究 (SOF) 的 2,855 名女性中，我们检查了自我报告与活动记录测量的短期和正常 (> 6 但 < 9) 的一致性和准确性小时）睡眠时间。我们评估了选择因素（人口统计学、医学、身体和神经精神疾病、药物和物质使用以及睡眠相关措施）与假阴性风险（自我报告的正常睡眠时间，但活动记录的睡眠时间短）之间的关联，以及分别使用逻辑回归进行假阳性（自我报告的短睡眠时间和活动记录的正常睡眠时间）指定。

结果：

男性和女性的平均年龄分别为 76.3 ± 5.5 和 83.5 ± 3.7 岁。自我报告的睡眠持续时间和活动性睡眠持续时间之间的一致性较差（Kappa ≤ 0.24）。近一半的老年人出现假阴性，超过四分之一的老年人出现假阳性。在男性和女性的多变量模型中，假阴性与肥胖、白天嗜睡和打盹独立相关，而假阳性与肥胖显着降低。

结论：

报告不足和过度报告短睡眠在老年人中很常见。依赖自我报告可能会导致错失预防不良后果或不必要干预的机会。在评估睡眠时间对健康结果的影响时，应客观确认自我报告的睡眠时间。
