我们的研究提供了一个大的英国人口为基础的队列主观睡眠概况。报告的卧床时间（TIB）比睡眠时间长1.5小时以上。所有社会人口学因素随TIB和睡眠时间而变化。睡眠比例可能是这一人群睡眠模式的一个有用指标。睡眠模式与各种健康结果有关，但英国人口的睡眠模式尚未得到广泛报道。我们的目的是描述欧洲癌症前瞻性调查（EPIC）-诺福克参与者报告的睡眠特征，特别强调睡眠量测量的比较。从2006年到2007年，共有8480名45-90岁的参与者报告了睡眠时间，夜间睡眠时间和睡眠困难。根据起床时间与就寝时间之差计算卧床时间（TIB），睡眠比例定义为睡眠时间与TIB的比值。平均而言，报告的TIB比睡眠持续时间长1.5小时以上。与男性相比，女性在床上的时间长15分钟，但睡眠时间短11分钟，睡眠困难更多。在多变量分析中，睡眠时间和TIB随社会经济因素而变化，但女性，非工作者和老年人以及丧偶，分居或离婚的人的睡眠比例始终较低;那些报告睡眠困难和更频繁使用睡眠药物的人;以及那些受教育程度较低，总体健康状况较差或重度抑郁症（MDD）的人。自我报告的睡眠时间和TIB对健康有不同的意义和影响。睡眠比例可能是一般人群睡眠模式的一个有用指标。
Our study provides a subjective sleep profile of a large British population–based cohort. The reported time in bed (TIB) was more than 1.5 h longer than sleep duration. All sociodemographic factors varied with TIB and sleep duration. Sleep proportion may be a useful indicator of sleep patterns in this population. Sleep patterns have been linked to various health outcomes, but sleep patterns in the British population have not been extensively reported. We aimed to describe the sleep characteristics reported by the European Prospective Investigation of Cancer (EPIC)-Norfolk participants, with a particular emphasis on the comparison of measures of sleep quantity. From 2006 to 2007, a total of 8480 participants aged 45–90 years reported sleep timing, nighttime sleep duration, and sleep difficulties. Time in bed (TIB) was calculated from the difference between rise time and bedtime, and sleep proportion was defined as the ratio of sleep duration and TIB. On average, the reported TIB was more than 1.5 h longer than sleep durations. Compared to men, women spent 15 min longer in bed, but they slept for 11 min less and reported more sleep difficulties. In multivariate analysis sleep duration and TIB varied with socioeconomic factors, but sleep proportion was consistently lower among women, nonworkers, and older individuals, as well as those who were widowed, separated, or divorced; those who reported sleep difficulties and more frequently used sleep medication; and those who had lower education, poorer general health, or a major depressive disorder (MDD). Self-reported sleep duration and TIB have different meanings and implications for health. Sleep proportion may be a useful indicator of sleep patterns in the general population.
