OBJECTIVE: Injury proneness is common in adolescents, but the role of individual factors has received little attention. This study assessed the relationships of a number of individual characteristics with frequency of school injuries. METHODS: This prospective study was conducted on 2396 students from middle schools and high schools in an urban area in France over one school year. A questionnaire was completed by each student at the beginning of the school year, and an injury questionnaire was completed for all injuries that occurred at school during the year. Data were analysed using the chi2 independence test and logistic models. RESULTS: Over the study year, 10.6% of the students had a single injury. Frequent injuries (two or more) were common (2.3%) and were strongly related to younger age [adjusted odds ratio (aOR) 1.52, 95% confidence interval (95%CI) 1.28-1.79], frequent use of psychotropic drugs (aOR 2.03, 95%CI 1.06-3.86) and a poorer average school mark (<10/20, aOR 2.58, 95%CI 1.30-5.12). The occurrence of a single injury was less strongly related to younger age (aOR 1.20, 95%CI 1.11-1.30) and frequent use of psychotropic drugs (aOR 1.43, 95%CI 1.04-1.96), and was also associated with parental absence (aOR 1.33, 95%CI 1.00-1.77), not being calm (aOR 1.41, 95%CI 1.03-1.89) and not being easily irritated (aOR 1.56, 95%CI 1.14-2.13). CONCLUSIONS: This study identified a number of factors associated with injury frequency. This information could be useful for injury prevention. Physicians could help students, parents, teachers and school staff to be more aware of the risks and to find remedial measures.
