Passive Commuting and Dietary Intake in Fourth and Fifth Grade Students

Promoting active commuting by walking or biking to and from school could increase physical activity and reduce obesity among youth. However, exposure to the retail food environment while commuting may lead to greater dietary intake among active commuters.To examine the relationship between commute patterns and dietary intake and quality in elementary students.Fourth and fifth grade students (N=3,316) in 44 California schools reported commute modes to and from school and dietary intake for the same 24-hour period in 2012. Differences between active and passive commuters in total energy intake (kcal), energy from purchased foods, and energy from sweets and snack-type foods were compared, stratified by after-school program (ASP) participation (analysis conducted in 2013).Twenty-three percent of youth actively commuted to school; 27% actively commuted from school. Passive commuters, 87% of whom traveled by car, consumed 78 more kcal from purchased foods (p0.01) than active commuters in the 24-hour period, though total energy intake did not differ by commute mode overall or by ASP participation. Among the 72% of students who did not attend an ASP, passive commuters consumed 56 more kcal from purchased foods (p0.01) and 25 more kcal from sweets and snack-type foods (p=0.02) than active commuters.Passive commuters consumed more sweets and snack-type foods and more purchased foods than active commuters. These results, which suggest that parents are providing unhealthy foods for their children during the school commute, reinforce the need for multilevel strategies to promote energy balance in youth.
