Trends in medically attended injuries among Czech adolescents between 2002 and 2022

Adolescence is widely recognized as a critical developmental period marked by increased independence and risk-taking behaviours, which often result in medically attended injuries. The aim of the study is to present the trends analyses of self-reported HBSC data on medically attended injuries in Czech adolescents between the years 2002 and 2022 and complement other sources of injuries data in Czech adolescents. Additional objective is to outline the possible use of the above-mentioned data for research purposes by public health professionals and researchers so they can be used for injury prevention purposes.

The overall sample of 44,817 adolescents aged 11, 13 and 15 years (50.3% girls) from the last six cycles of the Health Behaviour in School-aged Children study data collections between 2002 and 2022 was analysed.

An adjusted residual analysis of nationally representative data from 2002 to 2022 revealed a significant shift in the pattern of medically attended injuries among Czech adolescents. Across both sexes and all surveyed age groups, there was a notable increase in the prevalence of multiple (2 or more) injuries. Simultaneously, the proportion of adolescents reporting no injuries decreased significantly, particularly among girls, whose injury-free rate dropped from 61.2% in 2002 to 48.2% in 2022. While the rate of single injuries remained relatively stable - without significant change in many groups - the overall injury burden has shifted toward more frequent and potentially severe injury experiences. Logistic regression analysis revealed that the likelihood of reporting at least one injury was highest in 2022, after controlling for gender, age, and family affluence. Boys, 13-year-olds, and children from higher-income families were at increased risk.

Medically attended injuries have increased in both frequency and complexity over the last two decades among Czech adolescents. The shifting patterns underscore the urgent need for context-sensitive, age-appropriate, and equity-focused prevention strategies.
