我们的目的是在美国人口的全国代表性样本中，按性别和种族提供跨寿命的客观测量的睡眠参数。该研究包括来自2011-2014年国家健康和营养检查调查（NHANES）的11，279名6岁及以上的参与者，他们至少有3天的有效睡眠参数，这些参数是根据7天24小时加速度计记录计算的。睡眠时间与年龄呈U型关系，在40岁时达到最低点，在50岁左右开始再次增加。睡眠起始时钟时间（CTSO）随年龄增长而延迟，在20岁左右达到最大值。CTSO随后增长至50岁，直至70岁趋于平稳，然后在70岁后再次增长。睡眠效率在整个生命周期中呈整体下降趋势，但从30岁到60岁左右保持稳定。美国20多岁的年轻人最晚在午夜前后睡觉，而40至50岁的中年人睡得最少。女性的睡眠时间通常比男性长，但更有可能出现较晚的睡眠开始，特别是在年龄较大的时候。与其他种族相比，非西班牙裔黑人表现出更差的睡眠特征，即睡眠时间较晚，睡眠时间较短，睡眠效率较低。总之，这项研究提供了有价值的见解，美国居民的睡眠习惯的特点，通过使用客观测量的睡眠参数，并将有助于指导个性化的建议，睡眠卫生。
We aimed to provide objectively measured sleep parameters across lifespan by sex and race in a national representative sample of US population. The study included 11,279 participants 6 years and older from the National Health and Nutrition Examination Survey (NHANES) 2011–2014, who had at least 3 days of valid sleep parameters calculated from 7-day 24-h accelerometer recording. Sleep duration showed a U-shaped association with age and reached the minimum at age 40 and started to increase again around age 50. The clock time for sleep onset (CTSO) delayed with age and reached the maximum at about age 20. CTSO then advanced until age 50, leveled off until age 70, then advanced again after age 70. Sleep efficiency showed an overall decreasing trend across the lifespan but stabilized from age 30 to about age 60. US young adults in age 20 s are the ones who slept at the latest around midnight, while the middle aged US residents between 40 and 50 years old slept the least. Females generally present longer sleep duration than males, while more likely to have later sleep onset, particularly at older ages. Non-Hispanic Blacks showed worse sleep characteristics, i.e. sleep later, sleep shorter, and sleep less efficiently, compared to other racial groups. In conclusion, this study provides valuable insights on the characteristics of sleep habits of residents of the United States by using objectively measurements of sleep parameters and will help guide personalized advice on sleep hygiene.
