introduction Several studies have examined how confinement restrictions imposed to stop the spread of COVID-19 have affected the movement behaviors of children and adolescents, but there is a need to synthesize these findings. Therefore, we conducted this systematic review to examine the impact of COVID-19-related confinement on the movement behaviors of children and adolescents.
Methods We searched eight databases and gray literature for relevant studies of all study designs; and performed a narrative analysis of the results after synthesis without meta-analysis guidelines. We used appropriate tools to assess risk of bias in quantitative and qualitative studies. We compared changes in physical activity, screen time, and sleep duration and quality from before to during the COVID-19 lockdown.
Results This review included 71 studies reporting data from 35 countries and territories, mostly high-income economies. The majority of studies used a cross-sectional design and had fair to poor quality ratings. Most studies have reported reduced physical activity, increased screen time, and longer hours of sleep in children and adolescents. Children and teens facing strict lockdowns experienced greater declines in physical activity and greater increases in screen time than those under light restrictions.
Conclusion COVID-19 related lockdowns have been detrimental to the movement behaviors of children and adolescents, with stricter lockdowns tending to have a greater impact. Children and teens under COVID-19 restrictions are likely to be less active, spend more screen time, and sleep longer than before the lockdown. More studies in low- and middle-income countries could provide a clearer picture of impact
