Correction Lucy Abel, BioMed Central 13 December 2012 After publication the authors noticed that the reference to the paper by Seghers and Rutten in this article, reference number 6, was listed incorrectly. This paper was published in 2010 instead of 2011. The correct reference is: Seghers J, Rutten C: Clustering of multiple lifestyle behaviours and its relationship with weight status and cardiorespiratory fitness in a sample of Flemish 11- to 12-year-olds. Public Health Nutrition 2010, 13:1838-1846. The authors apologize for this error. Competing interests I am the Journal Development Editor for IJBNPA.
