Abstract

BACKGROUND

This study reports the accelerometer-based physical activity (PA) and sedentary behavior (SB) before and during the COVID-19 pandemic in hypertensive older adults.

METHODS

Thirty-five hypertensive older adults were included in this observational study. Accelerometer-based PA and SB measures were assessed before (January to March 2020) and during (June 2020) the COVID-19 pandemic. Linear mixed models were used to assess within-group changes in PA and SB measures, adjusted by accelerometer wear time.

RESULTS

Before COVID-19 pandemic participants presented: 5809 steps/day (SE = 366), 303.1 min/day (SE = 11.9) of light PA, 15.5 min/day (SE = 2.2) of moderate-vigorous PA, and 653.0 min/day (SE = 12.6) of SB. During COVID-19 pandemic there was a decrease in steps/day (β = -886 steps/day, SE = 361, p = 0.018), in moderate-vigorous PA (β = -2.8 min/day, SE = 2.4, p = 0.018), and a trend in light PA (β = -26.6 min/day, SE = 13.4, p = 0.053). In addition, SB increased during the COVID-19 pandemic (β = 29.6 min/day, SE = 13.4, p = 0.032). The magnitude of changes was greater on the weekend, mainly for steps/day (β = -1739 steps/day, SE = 424, p < 0.001) and the SB pattern (more time spent in bouts of ≥10 and 30 min, less breaks/day and breaks/h).

CONCLUSIONS

The COVID-19 pandemic may elicit unhealthy changes in movement behavior in hypertensive older adults. Lower PA, higher and more prolonged SB on the weekend are the main features of the behavioral changes.

摘要

背景

本研究报告了高血压老年人群在 COVID-19 大流行前后基于加速度计的身体活动（PA）和久坐行为（SB）。

方法

本观察性研究纳入了 35 名高血压老年人。使用加速度计评估 COVID-19 大流行前（2020 年 1 月至 3 月）和期间（2020 年 6 月）的 PA 和 SB 测量值。线性混合模型用于评估 PA 和 SB 测量值的组内变化，通过加速度计佩戴时间进行调整。

结果

在 COVID-19 大流行之前，参与者的表现为：每天 5809 步（SE=366）、每天 303.1 分钟（SE=11.9）的低强度 PA、每天 15.5 分钟（SE=2.2）的中高强度 PA 和每天 653.0 分钟的 SB。在 COVID-19 大流行期间，每天的步数减少了（β=-886 步/天，SE=361，p=0.018），中高强度 PA 减少了（β=-2.8 分钟/天，SE=2.4，p=0.018），低强度 PA 呈减少趋势（β=-26.6 分钟/天，SE=13.4，p=0.053）。此外，SB 在 COVID-19 大流行期间增加（β=29.6 分钟/天，SE=13.4，p=0.032）。周末的变化幅度更大，主要是每天的步数（β=-1739 步/天，SE=424，p<0.001）和 SB 模式（更多时间处于 10 分钟和 30 分钟以上的时间段，每天的休息时间和休息次数减少）。
