COVID-1 9 大流行导致社会层面的睡眠和其他行为模式发生变化。客观数据将有助于更好地了解人口层面与睡眠相关的变化。来自美国 6 个主要城市的约 163,524 名 Fitbit 活跃用户贡献了数据，代表了受疫情影响特别严重的地区（芝加哥、休斯顿、洛杉矶、纽约、旧金山和迈阿密）。提取的睡眠变量包括每晚和每周的平均睡眠持续时间和就寝时间，以及睡眠持续时间和就寝时间的变异性（标准差）。研究人员检查了 2018 年和 2019 年类似时间范围的偏差，以及大流行期间这些睡眠指标的变化、与静息心率变化的关系，以及 5 月和 6 月重新开放期间的变化。总体而言，与 2019 年相比，2020 年几乎所有组的平均睡眠持续时间都较高，几乎所有组的平均睡眠时相均推迟，几乎所有组的平均睡眠持续时间和就寝时间变异性均下降（由于工作日与周末的差异减少）。 2020 年 1 月至 4 月期间，平均睡眠时间增加，平均就寝时间推迟，平均睡眠时间变异性减少。观察到的静息心率变化与睡眠变化呈正相关，与活动水平呈负相关。在接下来的几个月（5 月和 6 月）中，许多变化开始回归历史正常水平。(c) 2021 年由 Elsevier Inc. 代表国家睡眠基金会发布。
The COVID-1 9 pandemic has resulted in societal-level changes to sleep and other behavioral patterns. Objective data would allow for a greater understanding of sleep-related changes at the population level. About 163,524 active Fitbit users from 6 major US cities contributed data, representing areas particularly hard-hit by the pandemic (Chicago, Houston, Los Angeles, New York, San Francisco, and Miami). Sleep variables extracted include nightly and weekly mean sleep duration and bedtime, and variability (standard deviation) of sleep duration and bedtime. Deviation from similar timeframes in 2018 and 2019 were examined, as were changes in these sleep metrics during the pandemic, relationships to changes in resting heart rate, and changes during re-opening in May and June. Overall, compared to 2019, mean sleep duration in 2020 was higher among nearly all groups, mean sleep phase shifted later for nearly all groups, and mean sleep duration and bedtime variability decreased for nearly all groups (owing to decreased weekday-weekend differences). Over the course of January to April 2020, mean sleep duration increased, mean bedtime shifted later, and mean sleep duration variability decreased. Changes in observed resting heart rate correlated positively with changes in sleep and negatively with activity levels. In later months (May and June), many of these changes started to drift back to historical norms.(c) 2021 Published by Elsevier Inc. on behalf of National Sleep Foundation.
