Child Motor Development before and after the COVID-19 Pandemic: Are There Social Inequalities?

Background: COVID-19 pandemic has influenced all children's motor development. We examine whether this differs by social circumstances. We hypothesise that socially disadvantaged children experienced more pronounced motor problems compared with better-off children.

Methods: Our trend study includes three representative waves of preschoolers (school years 2018/19, 2019/20, 2023/24) from a German school enrolment medical screening. Based on logistic regressions, we computed predicted prevalences of motor problems separately for children in different social circumstances (neighbourhood, migration background, family status).

Results: Motor development of preschoolers slightly worsened by 2023 compared to pre-pandemic level (6.3 percent 2018 to 7.4 percent 2023). Results by neighbourhood highlight that preschoolers from well-off districts experienced a deterioration of motor development (4.9 percent 2018-6.4 percent 2023). The prevalence of motor problems is, however, below that of children from deprived neighbourhoods with consistently high prevalence (9.2-10 percent). Results by migration background show a worsening trend for children without migration background and the gap between the groups disappears in 2023. Results by family status do not indicate significant differences.

Conclusion: Contrary to our hypothesis, socially disadvantaged children experienced smaller change in motor problems. However, our results highlight the potential of structured physical activities in daycare centres and sports facilities to enhance the motor development of these children.
