Shifts in Self-Reported Physical Activity, Sedentary Behavior, and Play Among Lower-Socioeconomic Children During the COVID-19 Pandemic: A Repeated Cross-Sectional Study.

Purpose: The lack of in-person schooling and participation in structured recreation activities during the COVID-19 pandemic may have altered children's movement behaviors. This study assessed changes in children's self-reported in school and out of school physical activity, sedentary behavior, and play before and during the pandemic.

Design: A repeated cross-sectional online survey was administered in February 2020 (pre-pandemic, in-person) and 2021 (during pandemic, remote).

Setting: Children attended an urban public school district in Phoenix (AZ) serving a low-income population.

Subjects: Students in grades 4-8 completed the survey in 2020 ( = 253, 62% response rate) and 2021 ( = 261, 77% response rate).

Measures: The survey included items from the Youth Activity Profile and three additional questions about play.

Analysis: Differences in mean scores and mean scores by gender were analyzed using one-way and two-way ANOVAs.

Results: Students reported less physical activity during remote recess in 2021 (M = 3.42, SD = .80 v. M = 2.99, SD = .86, < .05). Physical activity outside of school decreased during the pandemic (M = 2.76, SD = 1.26 v. M = 2.53, SD = 1.18, < .05). Most students (55%) reported playing less during the pandemic, but playing in new ways (67%).

Conclusion: Children may benefit from interventions to counter reduced movement experienced during the pandemic, particularly in under-resourced areas.
