Abstract

Background: The 24-h activity cycle (24H-ACT) (sleep, sedentary behavior, light physical activity, and moderate to vigorous physical activity) may have deleterious or beneficial associations with 24-h blood pressure (24H-BP).

Purpose: Estimate the short-term associated changes in 24H-BP with acutely replacing 30 min/d from one behavior of the 24H-ACT to other behaviors in employed adults.

Methods: Participants (N = 659) wore an ambulatory blood pressure monitor and two accelerometers (waist and wrist) to measure 24H-BP and the 24H-ACT.

Results: Replacing 30 min of sedentary behavior with 30 min of sleep was associated with lower 24-h mean systolic [ß = -0.32 mm Hg per 0.5 h (95% CI: -0.58, 0.06)] and diastolic [ß = -0.31 mm Hg per 0.5 h (95% CI: -0.50, -0.12)] blood pressure. Replacing 30 min of light physical activity with 30 min of sleep was associated with lower 24-h mean systolic [ß = -0.30 mm Hg per 0.5 h (95% CI: -0.62, 0.03,)] and diastolic blood pressure [ß = -0.34 mm Hg per 0.5 h (95% CI: -0.58, -0.11)]. No other time reallocations between 24H-ACT behaviors were associated with changes in 24H-BP.

Conclusion: Replacing time in sedentary behavior or light physical activity with sleep may provide small short-term reductions in that day's 24H-BP.

睡眠、久坐行为和体育锻炼之间的时间重新分配及其与 24 小时血压的关系。

背景：24小时活动周期（睡眠、久坐不动、轻体力活动、中度至剧烈体力活动）可能与24小时血压有有害或有益的关联。目的：估算在职成年人每天从24小时活动周期的一种行为急性替换为其他行为30分钟后，24小时血压的短期相关变化：方法：参与者（N=659）佩戴流动血压计和两个加速度计（腰部和腕部），测量 24 小时血压和 24 小时活动周期：用 30 分钟睡眠取代 30 分钟久坐不动的行为与降低 24 小时平均收缩压[ß=-0.32 mmHg/0.5小时（95% CI：-0.58, 0.06）]和舒张压[ß=-0.31 mmHg/0.5小时（95% CI：-0.50, -0.12）]有关。用 30 分钟睡眠代替 30 分钟的轻体力活动与降低 24 小时平均收缩压[ß=-0.30 mmHg/0.5小时（95% CI：-0.62，0.03）]和舒张压[ß=-0.34 mmHg/0.5小时（95% CI：-0.58，-0.11）]有关。24小时活动周期行为之间的其他时间重新分配与24小时血压变化无关：结论：以睡眠取代久坐不动或轻体力活动的时间，可在短期内小幅降低当天的 24 小时血压。
