The Canadian 24-Hour Movement Guidelines for Adults, released in October 2020, recommend 7 to 9 hours of good-quality sleep for adults aged 18 to 64 and 7 to 8 hours for adults aged 65 and older, on a regular basis, with consistent sleep and wake times for health benefits. This study assesses the sleep behaviours of Canadian adults and how these behaviours align with the recommendations.
This cross-sectional study uses nationally representative data from the 2020 Canadian Community Health Survey healthy living rapid response module (N = 9,248), collected from January to March 2020. Sleep behaviours were self-reported by respondents, and descriptive statistics were used to calculate means or percentages for sleep duration, guideline adherence, physical activity and screen time, sleep timing, and sleep variability in the full sample. This was done by age, sex, household education, household income adequacy and employment status.
Mean sleep duration was 7.9 hours for adults aged 18 to 64, with 77% meeting sleep duration recommendations, and 8.1 hours for adults aged 65 and older, with 55% meeting sleep duration recommendations. Among adults aged 18 to 64, 61% reported high sleep quality, compared with 71% among adults aged 65 and older. High sleep variability (≥30-minute difference between work and free days) and poor sleep-facilitating behaviours were prevalent. Adults who reported high sleep quality and high sleep variability were more likely to meet sleep duration recommendations.
To maximize health benefits, continued efforts are needed to promote good sleep behaviours among Canadian adults. Device-based measures of sleep could improve surveillance and research.
2020 年 10 月发布的《加拿大 24 小时身体活动指南》建议，18 至 64 岁成年人应定期获得 7 至 9 小时的高质量睡眠，65 岁及以上成年人应定期获得 7 至 8 小时的高质量睡眠，同时保持一致的睡眠和醒来时间，以促进健康。本研究评估了加拿大成年人的睡眠行为以及这些行为与建议的吻合程度。
本横断面研究使用了 2020 年加拿大社区健康调查健康生活快速反应模块（N=9248）的全国代表性数据，该数据于 2020 年 1 月至 3 月收集。睡眠行为由受访者自我报告，使用描述性统计方法计算了全样本中睡眠时间、指南依从性、身体活动和屏幕时间、睡眠时间和睡眠可变性的平均值或百分比。这是根据年龄、性别、家庭教育、家庭收入充足率和就业状况进行的。
18 至 64 岁成年人的平均睡眠时间为 7.9 小时，其中 77%符合睡眠时间建议，65 岁及以上成年人的平均睡眠时间为 8.1 小时，其中 55%符合睡眠时间建议。在 18 至 64 岁的成年人中，61%报告睡眠质量高，而 65 岁及以上的成年人中，71%报告睡眠质量高。高睡眠可变性（工作日和休息日之间相差≥30 分钟）和不良的睡眠促进行为普遍存在。报告睡眠质量高和睡眠可变性高的成年人更有可能符合睡眠时间建议。
为了最大限度地提高健康效益，需要继续努力促进加拿大成年人的良好睡眠行为。基于设备的睡眠测量方法可以提高监测和研究水平。
