Prevalence of School Active Commuting and Associated Factors in Chilean Children: Analysis of the National Survey on Physical Activity and Sport Habits

BACKGROUND: School active commuting is a key behavior to promote physical activity in children, yet limited evidence exists in Chile. This study examined its prevalence and associated factors among Chilean schoolchildren. METHODS: A cross-sectional study was conducted using data from the Chilean National Physical Activity and Sports Habits Survey, including a subsample of 1137 children aged 5-10 years derived from a nationally representative survey. School active commuting was defined as the dependent variable. Independent variables included sex, area of residence, socioeconomic status (SES), caregiver's education, self-rated health, leisure activities, and home-based physical or sedentary behaviors. FINDINGS: About one in three children (35%) reported commuting actively to school. Boys showed higher participation than girls, and active commuting was more common among children from lower SES households and among those whose caregivers had lower educational attainment. Children who preferred physical activities during leisure time were also more likely to commute actively. No differences were observed by geographic area, self-rated health, or home-based activity levels. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Schools and local communities should work together to ensure safe, equitable, and accessible environments that support active commuting. CONCLUSIONS: Active commuting remains low in Chilean children, emphasizing the need for multisectoral policies to promote physical activity and reduce inequalities.
