COVID-19 大流行扰乱了全世界日常生活的几乎所有方面。遏制疾病传播所需的公共卫生干预措施可能会产生意想不到的后果，除了短期死亡率之外，还会对长期健康结果产生不利影响。 1 例如，步数（身体活动的指标2）在 COVID-19 大流行初期明显低于大流行前。 3 尽管有疫苗，全球大流行仍然持续存在，了解其对身体活动（健康的重要决定因素4）的长期影响至关重要，并且可能有助于为公共卫生和区域政策决策提供信息。我们研究了自新冠肺炎 (COVID-19) 大流行爆发以来 2 年来全球体力活动趋势（以步数衡量）。我们假设全球身体活动量仍低于 COVID-19 之前的水平。我们使用了 2019 年 1 月 1 日至 2022 年 2 月 17 日的去识别个人数据，这些数据是从免费提供的 Azumio Argus 智能手机应用程序（一款流行的健康保健应用程序）收集的。每日步数是使用智能手机加速计和 Apple 或 Android 步数计数算法确定的。 5 用户位置由智能手机 IP 地址确定。使用 2019 年 1 月 1 日至 2019 年 12 月 31 日的数据计算每个区域的大流行前基线平均步数。COVID-19 区域病例数是从公开来源获得的。使用 Kruskal-Wallis 和 Conover 检验以及 Bonferroni 校正（p < 0·001）检查了不同时间窗口的平均步数的显着差异。这项研究由加州大学旧金山分校机构审查委员会 (20-30 539) 审查和豁免。研究期间，来自 200 多个国家和地区的 1,255,811 位唯一用户提供了总计 140,424,429 次每日步数测量数据； 92% 的智能手机是 iOS 系统，8% 是 Android 系统。在全球范围内，体力活动有所恢复，但与 2019 年疫情爆发前每天 5323 步的基线相比仍然较低（图）。与 2019 年至 2020 年大流行前相同的 90 天相比，所有大洲在研究期结束前（2021 年 11 月至 2022 年 2 月）的 90 天内的平均步数显着较低（p < 0·001）。同样的2020-2021年大流行中期90天期间也明显较低
The COVID-19 pandemic has disrupted nearly all aspects of daily life worldwide. Public health interventions necessary to curb disease spread could have unintended consequences that adversely influence long-term health outcomes beyond near-term mortality. 1 For example, step counts—a proxy for physical activity2—were markedly lower early in the COVID-19 pandemic than pre-pandemic. 3 As the global pandemic persists despite vaccines, understanding its long-term ramifications on physical activity—an important determinant of health4—is crucial, and might help to inform public health and regional policy decisions. We examined worldwide trends in physical activity, measured by step counts, 2 years since the onset of the COVID-19 pandemic. We hypothesised that worldwide physical activity remains lower than pre-COVID-19.We used deidentified individual-level data from Jan 1, 2019, to Feb 17, 2022, collected from the freely available Azumio Argus smartphone app, a popular health-wellness app. Daily step counts are determined using smartphone accelerometers and Apple or Android algorithms for step counting. 5 User location was determined by smartphone IP address. Pre-pandemic baseline mean steps were calculated per region using data from Jan 1, 2019, to Dec 31, 2019. COVID-19 regional case counts were obtained from publicly available sources. Significant differences in mean step counts for various time windows were examined using the Kruskal–Wallis and Conover’s tests with Bonferroni correction at p< 0· 001. This study was reviewed and exempted by the University of California, San Francisco Institutional Review Board (20–30 539). A total of 140 424 429 daily step count measurements were provided by 1 255 811 unique users from more than 200 countries and territories during the study period; 92% of smartphones were iOS, 8% were Android. Worldwide, physical activity has somewhat recovered but remains depressed compared with the pre-pandemic baseline of 5323 steps per day during the 2019 calendar year (figure). The mean step count in the 90 days preceding the end of the study period (November 2021–February 2022) was significantly lower for all continents compared with the same 90-day, 2019–2020 prepandemic period (p< 0· 001). The same 2020–2021 midpandemic 90-day period was also significantly lower
