Sitting Less, Moving More: A Compositional Data Analysis of Movement Behaviours and Adolescent Health-Related Quality of Life.

Key Points

• To examine the relationship between movement behaviours and health-related quality of life (HRQoL) in adolescents.
• Conducted compositional data analysis on movement behaviours.
• Evaluated the effects of sitting, standing, and movement intensity on HRQoL.
• Analyzed data separately for girls and boys.
• Sitting less and moving more correlates with improved HRQoL in adolescents.
• Replacing sitting with standing does not affect HRQoL.
• Girls benefit from light intensity movement while boys benefit from moderate-to-vigorous intensity.
