BACKGROUNDS AND AIM
Unhealthy eating behaviours increase with age and have been associated with adverse health consequences in adulthood. We examined the influence of screen-based sedentary behaviours (SBs) on unhealthy food consumption, such as energy-dense foods and sweetened drinks, among a representative sample of nearly 60 000 adolescents and assessed the role of possible modifiers.

METHODS
Data come from the Italian 2009-10 Health Behaviour in School-aged Children (HBSC) survey. Data on Eating patterns, SBs, physical activity, peers network, BMI and socio-economic status (SES) were collected following the HBSC study protocol. Hierarchical logistic regression models were used.

RESULTS
Unhealthy food consumption was significantly associated with a lower intake of fruit and vegetables and with the increase of SBs in both sexes and in all ages. The risk was interestingly higher in normal weight adolescents, in those with wider relationships with peers and in low SES children.

CONCLUSIONS
This study adds evidence to support the importance of investing more resources in educational initiatives both to increase parents' awareness to support adolescents on dietary choices and on time spent in screen-based behaviours, independently of their adiposity status; and to develop youth's ability to access and appropriately use media and technologies. Policy makers should also increase their attention on introducing regulatory policies on television food advertising to which youth are exposed.
