In the Original Article [1], the values for the BMI groups " < 18.5" and "18.5-23.9" were mistakenly swapped. The correct values should be as follows:

Moreover, the 4th paragraph of the ‘Movement behaviours analysis’ section in ‘Results’ mentioned incorrect statement as follows: "In addition, people with a lower BMI were on average more likely to have higher overall activity levels and were more frequently involved in physical activity (both MVPA and LIPA)."

The correct sentence should have been: "In addition, people with a normal BMI were on average more likely to have higher overall activity levels and were more frequently involved in physical activity (both MVPA and LIPA)."

Lastly, in the Supplementary, the first sentence of the “Evaluation of the model” was “The refined model achieved a Cohen’s kappa score of 0.667 (0.605, 0.749) and an accuracy of 0.811 (0.787, 0.853) on the CAPTURE-24CN dataset”.

The correct statement should have been: "The refined model achieved a Cohen’s kappa score of 0.674 (0.614, 0.743) and an accuracy of 0.814 (0.783, 0.851) on the CAPTURE-24CN dataset. "

The original article has been updated.
