Digital Media Usage Trends Among Children Aged 8-11 Years Before and After the COVID-19.

Objective: The coronavirus disease-2019 (COVID-19) pandemic has significantly altered daily life, potentially impacting children's digital media usage. This study investigates changes in smart device usage among children in South Korea, considering the pandemic's effects.

Methods: A longitudinal analysis was conducted on a cohort of 313 children aged 8-11 years from 2018 to 2021. The study measured weekly usage of personal computers (PCs), tablet PCs, and smartphones, comparing pre-pandemic (up to 2020) and post-pandemic periods. Partial correlation analysis was employed to assess the impact of COVID-19, controlling for covariates such as age, household income, and parental education.

Results: The analysis revealed a significant increase in smart device usage time following the onset of the pandemic. This increase remained statistically significant even after accounting for covariates. Notably, both age and maternal education level were significant factors influencing device usage.

Conclusion: This study demonstrates a significant shift in the digital behavior of children aged 8-11 in the context of the COVID-19 pandemic. The increase in smart device usage underscores the pandemic's far-reaching impact on children's daily routines and suggests a need for further research into its long-term effects. The findings highlight the importance of considering external societal changes when analyzing trends in digital media usage among children.
