BMJ子刊:证据来了——每天的运动、久坐和睡眠时间与全因死亡率之间的关

2021-07-07 MedSci原创 MedSci原创

睡眠, 久坐和LIPA对健康也有重要影响。

据估计,全球每年有390万-530万人过早死亡,全球医疗保健系统因此每年花费675亿美元。尽管我们都知道,缺乏运动与许多慢性疾病发生有关,但很少有人真正达到建议的身体活动水平。白天,我们主要花时间睡眠、久坐行为和轻度身体活动(LIPA),如散步。

每天进行中强度的身体活动(MVPA)对健康的益处是众所周知的,但越来越多的证据表明,睡眠, 久坐和LIPA对健康也有重要影响。继几年前加拿大、澳大利亚和英国推出儿童24小时运动指南后,加拿大最近发布了首个针对成年人和老年人的24小时综合公共卫生指南。

这些24小时指南结合了关于睡眠、久坐和身体活动的建议,但主要基于独立研究每种行为的影响得出的证据。且世卫组织2020年指南仅关注体力活动和睡眠不足。目前还没有证据表明睡眠时间、睡眠不足和体力活动与健康结果之间的联合联系。

为了回答这个问题,我们应将一天的24小时考虑在内——一天是有限的。为了研究每天花在不同强度体力活动、久坐行为和睡眠上的时间与全因死亡率之间的关联,来自英国格拉斯哥大学健康与生命科学学院的专家开展了相关研究,结果发表在BMJ子刊《英国运动医学杂志》(British Journal of Sports Medicine)上。

研究人员采用标准化的成分Cox回归分析,对六个前瞻性队列进行联合汇总分析,这些队列使用不同的设备测量参与者不同强度的体力活动、久坐行为和睡眠的市场。共纳入来自英国、美国和瑞典三国的参与者130239人,平均年龄54岁。主要的测量结局是全因死亡率(随访4.3-14.5年)。

使用手腕和髋部加速度计的研究提供了统计学上不同的结果(I2=92.2%,Q检验p<0.001)。总的来说,两者均没有看到睡眠时间和全因死亡率之间的关联,HR=0.96 (95%CI:0.67-1.12)。

使用手腕加速度计的汇总研究结果

但中度至剧烈体力活动的时间比例与全因死亡率较低显著相关。其中腕部加速计提示全因死亡降低37%(HR=0.63,95% CI 0.55-0.71),髋部则降低7%(HR=0.93,95% CI :0.87-0.98)。

与醒着时的其他行为相比,在MVPA度过的时间越长,全因死亡率的风险就越低。而醒着时的其他行为在大约20分钟/天之后趋于平缓,两者呈曲线剂量-反应关系。但这种益处因久坐时间延长而削减。对于每天超过11-12小时的久坐时间,益处完全减弱。

使用髋关节加速度计的汇总研究结果

同时髋关节加速度计研究发现,轻度体力活动时间与久坐时间存在显著相关性(HR=0.5)。在基于髋部加速度计的研究中,中度至剧烈体力活动与死亡率之间的关系通过轻度体力活动时间与久坐时间的平衡进行了修正。

综上,每天不同强度体力活动和久坐行为与全因死亡率之间存在联合剂量反应关系,但睡眠时间似乎并不显著。其中,中度到剧烈体力活动的时间能降低全因死亡。

J Pediatr:青少年们,出去玩吧

世界卫生组织建议青少年每天参加不低于60分钟的中等体力活动。研究显示,课后户外活动可以增加中等体力活动。在J Pediatrics发表的一项新研究中,研究者证实课后户外活动时间与中等体力活动成正相关。亚伯达大学的Lee Schaefer和Jonathan McGavock教授及其同事将306名青少年纳入健康心脏保护队列研究中来。在2008-2009学年,研究人员让受试者在网上填写一份调查问卷,自我
