背景在健康的老年受试者中，睡眠不佳的主观抱怨并不像人们从明显的客观年龄相关睡眠障碍中预期的那样频繁。这种差异可能取决于他们对睡眠感到满意所需的睡眠特征，这可能与年轻受试者不同。为了验证这一假设，我们的研究旨在确定睡眠满意度预测因子随年龄的变化。（睡眠潜伏期，睡眠持续时间，夜间觉醒的频率和持续时间）和定性（睡眠平静度、入睡难易度、睡眠满意度、觉醒难易度、觉醒后清新度和睡眠充足度），以及下午午睡的习惯进行了调查，在整个预先安排的采访健康的人：117例老年受试者（47名男性，70名女性，65-99岁）和120名年轻人（48名男性，72名女性，19-28岁）。定量睡眠特征随着年龄的增长而恶化，而定性睡眠特征在老年组中相当或甚至有所改善;只有“睡眠平静度”随着年龄的增长而下降。午睡习惯在老年人中增加，但似乎与睡眠满意度无关。睡眠满意度的预测因素不同年龄组：新鲜后觉醒，但不是夜间觉醒的频率是相关的老年人，而相反的是在年轻adults. CONCLUSIONSSThese研究结果强调，睡眠满意度是保存在健康的老年人，尽管定量夜间睡眠功能恶化，也反映了下午午睡的增加。这种差异可以解释为睡眠满意度的决定因素，对自发的适应性调整可能会发生在老年受试者的变化。与年轻人相比，老年人注意到清醒后的新鲜感，而很少注意夜间频繁的觉醒。
BACKGROUNDIn healthy aged subjects, subjective complaints of poor sleep are not as frequent as one would expect from the notable objective age-related sleep impairments. This discrepancy could depend on the sleep characteristics they require to feel satisfied about their sleep, which could be different from younger subjects. In order to verify this hypothesis, our study aims to identify changes in sleep satisfaction predictors as a function of age.METHODSSleep features, both quantitative (sleep latency, sleep duration, frequency and duration of night-time awakenings) and qualitative (calmness of sleep, ease of falling asleep, satisfaction with sleep, ease of awakening, freshness after awakening and sufficient sleep), as well as afternoon-nap habits were investigated throughout a pre-arranged interview in healthy individuals: 117 elderly subjects (47 men, 70 women, 65–99 years) and 120 young adults (48 men, 72 women, 19–28 years).RESULTSQuantitative sleep features worsen with age, whereas qualitative ones are equivalent or even improved in the aged group; only “calmness of sleep” decreases with age. Afternoon-nap habit increases in elderly subjects, but it does not appear to be linked to sleep satisfaction. Predictors of sleep satisfaction differ between age groups: freshness after awakening but not night-time awakenings frequency were relevant for elderly subjects, whereas the opposite was observed in young adults.CONCLUSIONSThese findings highlight that sleep satisfaction is preserved in healthy elderly individuals despite the worsening of quantitative night-time sleep features, also reflected by the increase of afternoon-naps. This discrepancy could be explained by changes in sleep satisfaction determinants, towards which a spontaneous adaptive adjustment is likely to occur in aged subjects. In contrast with young adults, elderly subjects heed the freshness perceived after the awakening and pay little attention to frequent night-time awakenings.
