Monitoring adolescent health behaviours and social determinants cross-nationally over more than a decade: introducing the Health Behaviour in School-aged Children (HBSC) study supplement on trends

Kuntsche and Ravens-Sieberer talk about the health behaviour in school-aged children. What emerges as a general picture of the 19 contributions included in this supplement is that, across countries, contemporary adolescents are better off than their counterparts were about a decade ago. In 2010, a higher proportion of adolescents ate healthily in terms of fruit and vegetable consumption, had a good dental hygiene, did not suffer from injury, were physically active on a daily basis, communicated with friends electronically, found it easy to talk to their mother or father about important personal issues, were not victimized in terms of occasional or chronic bullying, used a condom when having sex, did not drink alcohol on a weekly basis and lived tobacco and cannabis free.
