Following publication of this article, the authors noticed an error in the conclusion. The sentence: ‘The cut-points for moderate-to-vigorous PA were defined as ≥7503 for women and 9415 for men vector magnitude counts per minute (VMC) for PP and ≥4887 VMC/min for TP’, has now been corrected to: ‘The cut-points for moderate-to-vigorous physical activity were defined as ≥9515 for PP and ≥4887 VMC/min for TP’. This has been corrected in both the PDF and HTML versions of the article.
