BACKGROUND
During the 2020 UK COVID-19 lockdown restrictions, children spent almost all of their time at home, which had a significant influence on their physical activity (PA) and sedentary behaviour. This study aimed to: 1) determine changes to the social and physical environment at home and children's home-based sitting, PA, standing and sitting breaks as a result of the COVID-19 restrictions; and 2) examine associations between changes at home and children's movement behaviours.
METHODS
One hundred and two children had their PA and sitting, standing and sitting breaks at home objectively measured pre-COVID-19 and during the first COVID-19 lockdown (June-July 2020). Children's parents (n = 101) completed an audit of their home physical environment and a survey on the home social environment at both time points. Changes in the home physical and social environment and behavioural outcomes were assessed using Wilcoxon signed ranked tests, paired t-tests, or chi-square. Repeated linear regression analyses examined associations between changes in homes and changes in the home-based behavioural outcomes.
RESULTS
During COVID-19, households increased the amount of seated furniture and electronic media equipment at home. The number of books and PA equipment decreased and fewer parents enforced a screen-time rule. Children's preference for physical activities and socialising at home decreased. Time at home and sitting at home increased during COVID-19, whilst PA, standing and sitting breaks decreased. Both MVPA and TPA were positively associated with child preference for PA, and negatively associated with attending school. Sitting was negatively associated with child preference for PA and child preference for socialising at home. Media equipment was negatively associated with sitting breaks, whilst PA equipment was positively associated with standing.
CONCLUSION
The COVID-19 restrictions forced children to spend almost all their time at home. Children's PA, standing, and sitting breaks at home declined during the restrictions, while sitting increased. Mostly negative changes occurred in homes, some of which impacted children's behaviours at home. To avoid the changes persisting post-lockdown, interventions are needed to reset and promote children's PA and discourage prolonged sitting time.
背景
在 2020 年英国 COVID-19 封锁限制期间，儿童几乎所有时间都待在家里，这对他们的身体活动（PA）和久坐行为产生了重大影响。本研究旨在：1）确定由于 COVID-19 限制，家庭环境和儿童在家中久坐、PA、站立和坐姿休息时间的变化；2）研究家庭变化与儿童运动行为之间的关系。
方法
102 名儿童在 COVID-19 之前和第一次 COVID-19 封锁期间（2020 年 6 月至 7 月）在家中进行了 PA 和坐姿、站立和坐姿休息的客观测量。在这两个时间点，孩子们的父母（n=101）完成了家庭物理环境的审计和家庭社会环境的调查。使用 Wilcoxon 符号秩检验、配对 t 检验或卡方检验评估家庭物理和社会环境以及行为结果的变化。重复线性回归分析检查了家庭变化与家庭内行为结果变化之间的关系。
结果
在 COVID-19 期间，家庭增加了在家中使用的坐姿家具和电子媒体设备的数量。书籍和 PA 设备的数量减少，更少的父母执行了屏幕时间规则。儿童对在家进行身体活动和社交的偏好减少。在家时间和在家坐姿在 COVID-19 期间增加，而 PA、站立和坐姿休息时间减少。MVPA 和 TPA 与儿童对 PA 的偏好呈正相关，与上学呈负相关。坐姿与儿童对 PA 的偏好和儿童对在家社交的偏好呈负相关。媒体设备与坐姿休息时间呈负相关，而 PA 设备与站立时间呈正相关。
结论
COVID-19 限制迫使儿童几乎所有时间都待在家里。在限制期间，儿童在家中的 PA、站立和坐姿休息时间减少，而坐姿时间增加。家庭发生了大多是负面的变化，其中一些变化影响了儿童在家中的行为。为了避免限制结束后这些变化持续存在，需要采取干预措施来重置和促进儿童的 PA，减少长时间久坐。
