Multiple lifestyle risk behaviours and excess weight among adolescents in Barcelona, Spain.
OBJECTIVE
We aimed to analyse the prevalence of having multiple lifestyle risk behaviours (LRB) and the potential relationship between excess weight (including overweight and obesity) and cumulative multiple LRB among adolescents in Barcelona, Spain.


METHODS
A cross-sectional study was performed among a representative sample of 3,114 secondary school students in Barcelona. Height and weight were objectively measured and excess weight was defined in accordance with World Health Organization criteria. Information on screen time, breakfast, physical activity and sleep duration was obtained through a self-administered questionnaire.


RESULTS
More than 80% of the students had at least two LRBs. In compulsory schooling, the adjusted prevalence ratio (aPR) of excess weight increased with a higher number of reported LRBs (four LRBs: aPR=1.56; 95% confidence interval: 1.19-2.05).


CONCLUSIONS
These results highlight the importance of a multiple-behaviour approach in preventive programmes aimed at reducing adolescent obesity.
