A Ban on Smartphone Usage during Recess Increased Children's Physical Activity

Area of Science:

• Pediatrics
• Public Health
• Behavioral Science

Background:

• School recess is a critical period for children's physical activity.
• Smartphone use during recess is perceived as a significant barrier to physical activity.
• Understanding factors influencing recess physical activity is crucial for child health.

Purpose of the Study:

• To investigate the impact of a smartphone ban during recess on children's physical activity levels.
• To determine if restricting smartphone use affects the frequency and intensity of physical activity during school breaks.

Main Methods:

• A four-week smartphone ban was implemented during recess in six Danish schools (grades 4-7).
• Data were collected from 814 children at baseline and 828 at follow-up using questionnaires and systematic observation (SOPLAY).
• Statistical analysis, including odds ratios, was used to compare physical activity levels before and after the intervention.

Main Results:

• The mean frequency of physical activity significantly increased post-intervention (OR = 1.370).
• Moderate-intensity physical activity also significantly increased (OR = 1.387).
• Vigorous physical activity showed a significant decrease (OR = 0.851).

Conclusions:

• Banning smartphone usage during recess can enhance overall and moderate-intensity physical activity in schoolchildren.
• The positive effects were observed across different school settings (indoor/outdoor), genders, and grade levels.
• Further research is needed to fully understand the relationship between recess physical activity and smartphone use.
