Introduction A great number of studies describe reciprocal associations between unhealthy behaviours, such as poor sleep and nutrition and lack of physical activity, and mental health problems. Aims To investigate the relationship between unhealthy behaviours and depression, anxiety and well-being among Italian adolescents. Methods The sample comprised 1195 high-school pupils (mean age 15.3±0.6; 68% females) participating to the SEYLE (Saving and Empowering Young Lives in Europe) study, a randomized controlled trial, co-funded by the EU. Depression, anxiety and well-being were assessed using the Beck Depression Inventory II, the Zung Self-Assessment Anxiety Scale and the WHO-5 index. Unhealthy behaviours, such as short or long sleep, physical inactivity, skipping breakfast and not eating fruit and vegetables were also investigated. Results Controlling for age and gender, the unhealthy behaviours, with the exception of not eating fruit and vegetables, were all associated with poor level of well-being ( P P P Conclusions Unhealthy behaviours are often established early in life and are likely to be maintained during adulthood implying negative consequences for both physical and psychological well-being. Early combined health and mental health promotion programme should be implemented in order to boost their effectiveness.
