The World Health Organization (WHO) released guidelines for physical activity, sedentary behavior, and sleep for children under 5 years of age in 2019. In response to these guidelines, this pilot study aimed to (i) determine the proportion of preschool children (ages 3-4 years) who met the WHO guidelines; (ii) examine the feasibility of the proposed protocol for the SUNRISE study; and (iii) assess the impact of the COVID-19 pandemic on movement behaviors of preschool children in Bangladesh. Time spent in physical activity, sedentary behavior and sleep were objectively measured using two types of accelerometers (ActiGraph wGT3x-BT and ActivPAL4). Screen time and sleep quality were assessed via parent questionnaire. Fine and gross motor skills were measured using the Ages and Stages Questionnaire (3rd edition). Three executive functions were assessed using the Early Years Toolbox. Focus groups were conducted with parents and childcare staff to determine the feasibility of the protocol. Follow-up data during COVID-19 pandemic was collected from parents over phone. Data from 63 preschool-aged children and their parents was analyzed in this pilot study. Only three children (4.7%) met all components of the WHO guidelines. Separately, children meeting physical activity, sedentary screen time and sleep guidelines were 71.9%, 17.5%, and 59.7% respectively. The proportion of all children who were developmentally on-track for the gross and fine motor skills was 58.7% and 50.8%, respectively. Parents and educators reported that the protocol was feasible except for the activPAL-4 accelerometer. Approximately, 39% of children (14 out of 37) who wore this device developed itchy skin and rashes resulting in the suspension of using this device mid-way through data collection. During COVID-19, there was a significant decrease in children’s total physical activity (− 193 min/day), and time spent outside on weekdays (− 75 min/day) and weekend days (− 131 min/day) and a significant increase in sedentary screen time (+85 min/day). Only a low proportion of children met the WHO guidelines. Methods and devices (except ActivPAL4) used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bangladesh. Future measures should be taken to address the issue of movement behaviors of children during the time of pandemics like COVID-19.

早年 24 小时运动行为的国际研究（SUNRISE）：来自孟加拉国的试点研究

世界卫生组织 (WHO) 于 2019 年发布了 5 岁以下儿童体力活动、久坐行为和睡眠指南。根据这些指南，这项试点研究旨在 (i) 确定学龄前儿童（年龄3-4年）符合世界卫生组织指南的人；(ii) 审查 SUNRISE 研究拟议方案的可行性；(iii) 评估 COVID-19 大流行对孟加拉国学龄前儿童运动行为的影响。使用两种类型的加速度计（ActiGraph wGT3x-BT 和 ActivPAL4）客观测量体力活动、久坐行为和睡眠所花费的时间。通过家长问卷评估屏幕时间和睡眠质量。使用年龄和阶段问卷（第三版）测量精细和粗大运动技能。使用早期工具箱评估了三种执行功能。与家长和儿童保育人员进行焦点小组讨论，以确定该方案的可行性。COVID-19 大流行期间的后续数据是通过电话从家长那里收集的。这项试点研究对 63 名学龄前儿童及其家长的数据进行了分析。只有三名儿童（4.7%）符合世界卫生组织指南的所有内容。另外，符合体力活动、久坐屏幕时间和睡眠准则的儿童分别为 71.9%、17.5% 和 59.7%。粗大运动技能和精细运动技能发展正常的所有儿童比例分别为 58.7% 和 50.8%。家长和教育工作者报告说，除了 activPAL-4 加速度计之外，该协议是可行的。大约 39% 的佩戴该设备的儿童（37 名中的 14 名）出现皮肤瘙痒和皮疹，导致在数据收集过程中暂停使用该设备。在 COVID-19 期间，儿童的总体力活动量显着减少（− 193 分钟/天），工作日（− 75 分钟/天）和周末（− 131 分钟/天）的户外活动时间显着增加久坐的屏幕时间（+85 分钟/天）。只有一小部分儿童符合世界卫生组织的指导方针。该试点研究中使用的方法和设备（ActivPAL4 除外）被证明是可行的，这为在孟加拉国开展主要 SUNRISE 研究铺平了道路。未来应采取措施解决 COVID-19 等流行病期间儿童的行动行为问题。
