本研究报告了高血压老年人在COVID-19大流行之前和期间基于加速度计的身体活动（PA）和久坐行为（SB）。35名高血压老年人被纳入这项观察性研究。基于加速度计的PA和SB测量在COVID-19大流行之前（2020年1月至3月）和期间（2020年6月）进行了评估。使用线性混合模型评估PA和SB测量值的组内变化，并通过加速度计佩戴时间进行调整。2019冠状病毒病疫情前，与会者介绍：5809步/天（SE = 366），303.1分钟/天（SE = 11.9）轻度PA，15.5 min/天中度-剧烈PA（SE = 2.2），653.0 min/d（SE = 12.6）。在COVID-19大流行期间，每日步数减少（β = −886步/天，SE = 361，p = 0.018），中度-剧烈PA（β = −2.8分钟/天，SE = 2.4，p = 0.018），轻度PA（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，主要是步数/天（β =-1739步/天，SE = 424，p < 0.001）和SB模式（≥10和30分钟的发作时间更多，休息/天和休息/小时更少）。COVID-19大流行可能会导致高血压老年人的运动行为发生不健康的变化。行为改变的主要特征是周末PA降低、SB升高和延长。于COVID-19疫情期间，观察到运动行为出现不健康的变化。高血压老年人减少了每天的步数和体力活动时间。观察到久坐行为（SB）所花费的时间增加。延长SB的时间增加，SB的中断减少。运动行为的不健康变化在周末发生较大。
This study reports the accelerometer-based physical activity (PA) and sedentary behavior (SB) before and during the COVID-19 pandemic in hypertensive older adults. 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. 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). 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. Unhealthy changes in movement behavior were observed during the COVID-19 pandemic. Hypertensive older adults decreased steps/day and time spent in physical activities. An increase in time spent in sedentary behavior (SB) was observed. The time spent in prolonged SB increased and the breaks in SB decreased. Greater unhealthy changes in movement behavior occurred on weekend.
