Odds ratios (OR) with 95% confidence interval (CI) for measures of physical activity by age groups among boys and girls. The age groups on the x-axis are ≤16 years (n = 14,313), 17 years (n = 23,614), 18 years (n = 21,313) and ≥19 years (n = 11,434) and the reference group is ≤16 year old boys. P-values represent the log likelihood test for the model including the interaction between sex and age category compared to the model without
