Figure 5.

Two line graphs show annual trends from 2020 to 2024. Panel A uses blue circular markers to display age-, sex-, and grade-adjusted composite fitness scores, increasing in 2021, falling in 2022, and rising again in 2023 and 2024. Panel B uses red square markers to show sex- and grade-standardized BMI-defined abnormality prevalence, which increases continuously across the five years. Error bars represent 95% confidence intervals. The panels use separate y-axes because the two indicators are measured on different scales.

Annual trajectories of the composite fitness score and BMI-defined abnormality, 2020–2024. Panel (A) shows age-, sex-, and grade-adjusted composite-score estimates (non-monotonic: An increase in 2021, a decline in 2022, and a further increase in 2023–2024). Panel (B) shows BMI-defined abnormality prevalence directly standardised to the pooled sex and grade distribution (a monotonic rise from 23.6 to 31.1%). Error bars are 95% confidence intervals. Separate panels are presented because the indicators are measured on different scales and should not be interpreted as directly interchangeable.
