[Accidental morbidity in adolescence: a retrospective study in 12 to 15 year-old school children in Switzerland] .

Mortality and morbidity from injuries in the adolescent population is substantial in Switzerland as all over the world. The estimation of morbidity from injuries is difficult and depends on the design of the study. Little information is available on morbidity between ages 12 and 15. The Health Behaviour in School-Aged Children (HBSC) study is an international survey based on a self-administered questionnaire for which the Swiss Institute for Prevention of Alcohol and Drug Problems (SIPA) is responsible in Switzerland. 7196 schoolchildren aged 12 to 15 participated in the 1998 survey. Questions covered subjects such as health and health behaviour. A few questions covered injuries, with reference to frequency, context and consequences. 45.3% of adolescents have been treated at least once by a nurse or a doctor for an injury during the past 12 months. It can be deduced that nearly 149,000 adolescents aged between 12 and 15 are injured in more than 260,000 accidents in Switzerland. The rate of injury is 793 per 1000 adolescents per year. Furthermore, one adolescent out of ten injures himself three times or more per year. In conclusion, morbidity due to injuries in adolescents aged 12 to 15 in Switzerland is therefore considerable. This study demonstrates the high prevalence of repeated injuries in adolescents.
