Accelerometer-based sedentary time and physical activity with incident and progressive tobacco smoking in 2503 children: A 13-year mediation and temporal longitudinal study

In the present study, engaging in MVPA from age 11 years may prevent 9 in 1000 children from starting smoking at the age of 13 years when smoking prevalence was 15 in 1000 children, i.e potentially preventing 60% of children from initiating smoking. However, the MVPA preventive approach diminished as children grew into young adults.
