Abstract

BACKGROUND

Mid-March 2020, Belgium went in lockdown to combat the COVID-19-pandemic. Having to provide school-based day care and adapt to online teaching, while all social, cultural and sports events and activities were cancelled, secondary school teachers' physical activity (PA) and sedentary behaviour (SB) may have been affected considerably. This study investigates the impact of the first Belgian lockdown on PA and SB in Flemish secondary school teachers.

METHODS

This prospective cohort study was conducted throughout the 2019-2020 school year. PA and SB measured in March/April 2020 were compared with a pre-lockdown measurement in January/February 2020. Other pre-lockdown measurements (September/October 2019 and November/December 2019) and one other during-lockdown measurement (May/June 2020) allowed us to control for confounding. Validated questionnaires were used to assess participants' PA and SB. Generalized linear mixed models were applied in R.

RESULTS

Among 624 participants (77·2% females, 43·3 ± 10·3 years), increases were observed for total PA (+ 108 min/week; p = 0·047), moderate PA (+ 217 min/week; p = 0·001), domestic and garden PA (+ 308 min/week; p < 0·0001) and leisure-time PA (+ 131 min/week; p < 0·0001), whereas work-related PA (-289 min/week; p < 0·0001) and active transportation (-38 min/week; p =0·005) decreased. No differences were observed for walking (p = 1·0) and vigorous PA (p = 0·570). Increases were found for total SB (+ 972 min/week; p < 0·0001), work-related SB (+ 662 min/week; p < 0·0001) and leisure-time SB (+ 592 min/week; p = 0·0004), whereas transport-related SB (-290 min/week; p < 0·0001) decreased.

CONCLUSION

During the lockdown, we found in our sample that Flemish secondary school teachers showed an increase in SB that was 9 times as high as their PA increase. As a government, education network or school, it is crucial to sensitize, promote, and facilitate sufficient MVPA and/or walking, but likewise to discourage SB during pandemic-induced lockdowns.

摘要

背景

2020 年 3 月中旬，比利时为应对 COVID-19 大流行而进入封锁状态。为了提供基于学校的日托服务，并适应在线教学，同时取消了所有社会、文化和体育活动，中学教师的身体活动（PA）和久坐行为（SB）可能受到了相当大的影响。本研究调查了第一次比利时封锁对弗拉芒语区中学教师 PA 和 SB 的影响。

方法

这是一项前瞻性队列研究，在整个 2019-2020 学年进行。2020 年 3 月/4 月测量的 PA 和 SB 与 2020 年 1 月/2 月的封锁前测量进行了比较。其他封锁前测量（2019 年 9 月/10 月和 11 月/12 月）和一次封锁期间测量（2020 年 5 月/6 月）允许我们控制混杂因素。使用经过验证的问卷评估参与者的 PA 和 SB。广义线性混合模型在 R 中应用。

结果

在 624 名参与者中（77.2%女性，43.3±10.3 岁），总 PA 增加了（+108 分钟/周；p=0.047），中等强度 PA 增加了（+217 分钟/周；p=0.001），家庭和花园 PA 增加了（+308 分钟/周；p<0.0001），休闲时间 PA 增加了（+131 分钟/周；p<0.0001），而工作相关 PA 减少了（-289 分钟/周；p<0.0001），积极交通减少了（-38 分钟/周；p=0.005）。步行（p=1.0）和剧烈 PA（p=0.570）没有差异。总 SB 增加了（+972 分钟/周；p<0.0001），工作相关 SB 增加了（+662 分钟/周；p<0.0001），休闲时间 SB 增加了（+592 分钟/周；p=0.0004），而交通相关 SB 减少了（-290 分钟/周；p<0.0001）。
