Impact of Virtual Education Versus Traditional Learning Modalities on the Body Mass Index of Students During the COVID-19 Pandemic in Western Saudi Arabia: A Cross-Sectional Study.

Objective:  The emergence of the coronavirus disease has forced governments worldwide to implement non-pharmaceutical interventions that imposed strict confinement policies on their populations, including children and adolescents. Subsequently, the education system has shifted from traditional to online classroom settings, introducing physical and lifestyle changes in students. This study aimed to determine the impact of virtual education in comparison with that of traditional education on body weight among school-age students in western Saudi Arabia.

Methods:  This cross-sectional study was carried out between March 2020 and May 2021 and assessed pediatric patients at the Pediatric Endocrine Clinic at King Abdulaziz Hospital, Jeddah, Saudi Arabia. A clinical interview was performed to collect data on sociodemographic characteristics, physical activity levels, and electronic device usage. Body mass index (BMI) was determined using the Center for Disease Control and Prevention standards.

Results:  In total, 518 participants (262 female and 256 male students) aged six to 18 years were assessed. The BMI significantly increased from a mean of 19.24, before the pandemic, to 20.08, after the commencement of the virtual study modality (p<0.001) that involved the increased use of electronic devices. Moreover, the proportion of physical inactivity significantly increased during weekdays (39%) and weekends (37.5%).

Conclusion:  Due to the many obesogenic factors influenced by the coronavirus disease 2019 (COVID-19) pandemic, the findings indicate the need for further research and interventions to avoid the incidence of overweight and obesity among students. Many obesogenic factors are influenced by the COVID-19 pandemic, which affect the student's physical activity and lifestyle by increasing the risk of overweight and obesity. Therefore Further research and interventions are needed.
