2019冠状病毒病大流行影响了日常生活的多个方面，包括与职业、交通和健康相关的行为。目前还不清楚这些日常生活的变化是如何影响身体活动和久坐行为的。在这项研究中，我们通过研究参与加州圣地亚哥正在进行的减肥试验的超重或肥胖年轻人中客观测量的日常身体活动和久坐行为的纵向变化，为COVID-19大流行对健康影响的研究增添了新的内容。在2019年11月1日至2020年10月30日期间，使用Fitbit Charge 3 （Fitbit LLC）收集了315名年龄在18至35岁之间的超重或肥胖（BMI范围：25.0-39.9 kg/m2）参与者的数据。经过严格筛选，找到持续磨损（每天10小时，≥250天）的有效数据后，对来自97名参与者的数据进行分析，以检测身体活动和久坐行为时间序列的多重结构变化。设计了一种检测多种结构变化的算法。这允许在ci的线性回归模型中自动识别和确定这些变化的日期。利用贝叶斯信息准则和残差平方和估计回归模型的断点个数；最优分割对应于最小贝叶斯信息准则和残差平方和。为了量化确定期间每个结果的变化，进行了线性混合效应分析。在关键人口统计学特征方面，纳入我们分析的97名参与者与被排除的210名参与者没有差异。2021年3月19日，加州开始实施“就地避难”命令后，步数显著减少（每天- 2872步，95% CI为- 2734至- 3010），轻度体育活动时间（- 41.9分钟，95% CI为- 39.5至- 44.3），中度至剧烈体育活动时间（- 12.2分钟，95% CI为- 10.6至- 13.8），久坐行为时间显著增加（+52.8分钟，95% CI为47.0-58.5）。下降幅度大于冬季假期期间观察到的预期下降幅度，截至2020年10月30日，它们尚未恢复到启动就地避难命令之前观察到的水平。在超重或肥胖的年轻人中，随着COVID-19缓解战略的实施，身体活动时间减少，久坐行为时间增加。与久坐不动的生活方式相关的健康状况可能是COVID-19大流行的额外意外后果。
The COVID-19 pandemic has impacted multiple aspects of daily living, including behaviors associated with occupation, transportation, and health. It is unclear how these changes to daily living have impacted physical activity and sedentary behavior. In this study, we add to the growing body of research on the health impact of the COVID-19 pandemic by examining longitudinal changes in objectively measured daily physical activity and sedentary behavior among overweight or obese young adults participating in an ongoing weight loss trial in San Diego, California. Data were collected from 315 overweight or obese (BMI: range 25.0-39.9 kg/m2) participants aged from 18 to 35 years between November 1, 2019, and October 30, 2020, by using the Fitbit Charge 3 (Fitbit LLC). After conducting strict filtering to find valid data on consistent wear (>10 hours per day for ≥250 days), data from 97 participants were analyzed to detect multiple structural changes in time series of physical activity and sedentary behavior. An algorithm was designed to detect multiple structural changes. This allowed for the automatic identification and dating of these changes in linear regression models with CIs. The number of breakpoints in regression models was estimated by using the Bayesian information criterion and residual sum of squares; the optimal segmentation corresponded to the lowest Bayesian information criterion and residual sum of squares. To quantify the changes in each outcome during the periods identified, linear mixed effects analyses were conducted. In terms of key demographic characteristics, the 97 participants included in our analyses did not differ from the 210 participants who were excluded. After the initiation of the shelter-in-place order in California on March 19, 2021, there were significant decreases in step counts (−2872 steps per day; 95% CI −2734 to −3010), light physical activity times (−41.9 minutes; 95% CI −39.5 to −44.3), and moderate-to-vigorous physical activity times (−12.2 minutes; 95% CI −10.6 to −13.8), as well as significant increases in sedentary behavior times (+52.8 minutes; 95% CI 47.0-58.5). The decreases were greater than the expected declines observed during winter holidays, and as of October 30, 2020, they have not returned to the levels observed prior to the initiation of shelter-in-place orders. Among overweight or obese young adults, physical activity times decreased and sedentary behavior times increased concurrently with the implementation of COVID-19 mitigation strategies. The health conditions associated with a sedentary lifestyle may be additional, unintended results of the COVID-19 pandemic.
