Associations between children's independent mobility and physical activity

Area of Science:

• Pediatric health
• Physical activity research
• Childhood development

Background:

• Independent mobility, or children's freedom to travel and play unsupervised, offers benefits like social skills and physical activity.
• However, its impact on physical activity accumulation remains under-explored.

Purpose of the Study:

• To investigate the associations between children's independent mobility and their accumulation of light, moderate-to-vigorous, and total physical activity.

Main Methods:

• A cross-sectional study of 375 Australian children (aged 8-13 years) used surveys for independent mobility and parent-child data.
• Objective physical activity was measured over four days using Actiheart monitors.
• Generalized linear models analyzed associations, controlling for covariates and sex interactions.

Main Results:

• Independent travel to school/destinations was not associated with overall physical activity levels.
• Independent walking/cycling to school positively correlated with total physical activity in boys only.
• Frequent independent outdoor play (≥3 days/week) was associated with higher light and total physical activity, particularly in girls.

Conclusions:

• Independent outdoor play may enhance children's daily physical activity, especially light-intensity activity, suggesting it as a potential intervention.
• Interventions promoting outdoor play could benefit children's physical activity, particularly girls.
• The link between independent travel and physical activity requires further research.
