Age related changes in sleep result in an increasing prevalence of poor sleep in mid-aged and older adults. Although physical activity has shown to benefit sleep in studies in controlled settings, this has not yet been examined in a real-life lifestyle program. The aims of this study were to: 1) examine the effects of a lifestyle program on moderate-to-vigorous physical activity and objective and subjective sleep in adults aged 55+ years; and 2) examine if the effects differed between good and poor sleepers.
This controlled pretest-posttest trial examined the effects of the 12-week group-based real-life lifestyle program 'Lekker Actief' on moderate-to-vigorous physical activity (measured using accelerometers) and sleep (measured using accelerometers and the Pittsburgh Sleep quality Index, PSQI). The main component of the program was a 12-week progressive walking program, complemented by an optional muscle strengthening program and one educational session on healthy nutrition. Of the 451 participants who were tested pre-intervention, 357 participants completed the posttest assessment (200 in the intervention group and 157 in the control group). Effects on moderate-to-vigorous physical activity and on objective sleep (sleep efficiency, total sleep time, wake time after sleep onset (WASO) and number of awakenings) as well as subjective sleep (sleep quality) were examined in crude and in adjusted multiple regression models. An interaction term between program (control versus intervention) and sleep category (good and poor) was included in all models.
Moderate-to-vigorous physical activity levels significantly increased in the intervention group compared with the control group (43,02 min per day; 95%CI: 12.83-73.22; fully adjusted model). The interaction terms revealed no differences between good and poor sleepers regarding the effect of the intervention on moderate-to-vigorous physical activity. There were no significant effects on sleep, except for good sleepers who showed an increase in number of awakenings/night by 1.44 (CI 95% 0.49; 2.24).
Although this program was effective in increasing physical activity, it did not improve sleep. Lifestyle programs should be promoted to increase physical activity, but more is needed to improve sleep as well. This trial was registered at ClinicalTrials.gov (Trial registration NCT03576209).
与年龄相关的睡眠变化导致中老年人群中睡眠质量差的患病率不断上升。尽管在对照研究中体育活动已被证明对睡眠有益，但在现实生活方式项目中尚未对此进行研究。本研究的目的是：1）研究一项生活方式项目对55岁及以上成年人中度至剧烈身体活动以及客观和主观睡眠的影响；2）研究睡眠状况良好者与睡眠状况不佳者之间的影响是否存在差异。
这项对照的前测-后测试验研究了为期12周的基于小组的现实生活方式项目“Lekker Actief”对中度至剧烈身体活动（使用加速度计测量）和睡眠（使用加速度计和匹兹堡睡眠质量指数（PSQI）测量）的影响。该项目的主要组成部分是一项为期12周的渐进式步行计划，并辅以一项可选的肌肉强化计划和一次关于健康营养的教育课程。在干预前接受测试的451名参与者中，357名参与者完成了后测评估（干预组200名，对照组157名）。在原始和调整后的多元回归模型中，研究了对中度至剧烈身体活动以及客观睡眠（睡眠效率、总睡眠时间、睡眠开始后的清醒时间（WASO）和觉醒次数）以及主观睡眠（睡眠质量）的影响。所有模型中均纳入了项目（对照组与干预组）和睡眠类别（良好与不佳）之间的交互项。
与对照组相比，干预组的中度至剧烈身体活动水平显著增加（每天43.02分钟；95%置信区间：12.83 - 73.22；完全调整模型）。交互项显示，在干预对中度至剧烈身体活动的影响方面，睡眠状况良好者与睡眠状况不佳者之间没有差异。除了睡眠状况良好者夜间觉醒次数增加1.44次（95%置信区间0.49；2.24）外，对睡眠没有显著影响。
尽管该项目在增加身体活动方面有效，但并未改善睡眠。应推广生活方式项目以增加身体活动，但还需要更多措施来改善睡眠。本试验已在ClinicalTrials.gov注册（试验注册号NCT03576209）。
