School start time and the healthy weight of adolescents (Canada)


posted by WM Admin on 1 August 2018

Studies have found that an early school start time is detrimental to the sleep, health, and well-being of youth, but its association with body weight remains unclear. The authors examined this association in 29,635 Canadian adolescents (ages 10-18) at 362 schools.

The authors found that a "later school start time was linked to lower BMI in Canadian adolescents". They suggest that delaying school start time may be an additional strategy to support the healthy weight of adolescents, but that future intervention and impact studies would be needed to confirm these findings.
