Area of Science:

  • Epidemiology
  • Public Health
  • Data Science

Background:

  • Childhood injuries pose a significant public health concern.
  • Effective prevention requires identifying high-risk groups.
  • Data-driven approaches are crucial for targeted interventions.

Purpose of the Study:

  • To explore epidemiological data of school children injuries.
  • To define specific risk groups for targeted prevention measures.
  • To propose a pruning procedure for entropy classification trees.

Main Methods:

  • Entropy classification of injury data from Koprivnica district, Croatia.
  • Development of a pruning procedure for classification trees, addressing uniformly populated and zero-populated classes.
  • Analysis of injury events based on multiple attributes.

Main Results:

  • Four distinct prevention groups were identified through entropy classification.
  • Group 1: Leg dislocations, sprains, and strains in boys (7-14 years) during home activities.
  • Group 2: Arm fractures in boys during home activities.
  • Group 3: Head open wounds in younger boys at school and road traffic incidents.
  • Group 4: Arm contusions in older girls at school and older boys in road traffic accidents.
  • These identified groups account for 57.2% of all analyzed injury cases.

Conclusions:

  • Entropy classification effectively identifies specific risk groups for childhood injuries.
  • The proposed pruning method enhances the accuracy of classification trees.
  • Findings provide a basis for developing targeted injury prevention strategies for school children.
