Objective: To investigate associations of daily breakfast consumption (DBC) with demographic and lifestyle factors in 41 countries. Methods: Design: Survey including nationally representative samples of 11–15 year olds (n = 204,534) (HBSC 2005–2006). Statistics: Multilevel logistic regression analyses Results: DBC varied from 33 % (Greek girls) to 75 % (Portuguese boys). In most countries, lower DBC was noticed in girls, older adolescents, those with lower family affluence and those living in single-parent families. DBC was positively associated with healthy lifestyle behaviours and negatively with unhealthy lifestyle behaviours.
