缺乏身体活动和睡眠障碍是老龄化社会的主要问题。越来越多的证据表明，身体活动与睡眠质量有关。然而，日常步行步数与睡眠之间的关系仍不清楚。这项前瞻性研究探讨了日本社区居住的老年人客观测量的每日步行步数和睡眠参数之间的关系。共招募了855名65岁及以上的社区居民，从2015年8月至2016年3月进行了不间断的随访。参与者平均每三个月佩戴腕带传感器7.8天。采用多元线性回归分析方法，分析每日步行步数与睡眠总时间、睡眠效率、入睡后觉醒时间（WASO）、夜间觉醒时间和午睡时间的关系。参与者的中位数（四分位距，IQR）年龄为73（69-78）岁，其中男性317（37.1%），女性538（62.9%）。中位（IQR）教育水平为12（11-12）年，中位（IQR）简易精神状态检查评分为29（27-30）分。在校正协变量和错误发现率后，每日步行步数与睡眠效率呈正相关，与WASO、觉醒时间计数和午睡时间呈负相关（β = 0.098，95%置信区间[CI]：0.034至0.162，p = 0.003; β = −0.107，95% CI：−0.172至−0.043，p = 0.001; β = −0.105，95% CI：-0.17至-0.04，p = 0.002; β =-0.31，95%CI：-0.371至-0.249，p < 0.001）。我们的研究结果可以帮助促进步行作为预防社区居住老年人睡眠障碍的干预措施。
Physical inactivity and sleep disturbances are major problems in an ageing society. There is increasing evidence that physical activity is associated with sleep quality. However, the association between daily walking steps and sleep remain unclear. This prospective study examined the relationship between objectively measured daily walking steps and sleep parameters in Japanese community-dwelling older adults. In total, 855 community-dwelling individuals aged 65 and above, with an uninterrupted follow-up from August 2015 to March 2016, were enrolled. The participants wore a wristband sensor for an average of 7.8 days every three months. Multiple linear regression analysis was performed to examine the relationship between daily walking steps and sleep parameters, including the total sleep time, sleep efficiency, time awake after sleep onset (WASO), awakening time count during the night, and naptime. The median (interquartile range, IQR) age of the participants was 73 (69–78) years, with 317 (37.1%) men and 538 (62.9%) women. The median (IQR) educational level was 12 (11–12) years, and the median (IQR) Mini-Mental State Examination score was 29 (27–30) points. The number of daily walking steps showed a positive correlation with sleep efficiency and an inverse correlation with WASO, awakening time count, and naptime, after adjusting for covariates and correcting for the false discovery rate (β = 0.098, 95% confidence interval [CI]: 0.034 to 0.162, p = 0.003; β = −0.107, 95% CI: −0.172 to −0.043, p = 0.001; β = −0.105, 95% CI: −0.17 to −0.04, p = 0.002; and β = −0.31, 95% CI: −0.371 to −0.249, p < 0.001, respectively). Our results can help promote walking as an intervention for preventing sleep disturbances in community-dwelling older adults.
