An international comparison of childhood injuries in Hong Kong
Insights
Childhood injuries in Hong Kong predominantly involve falls, with fewer poisonings and burns compared to international data. Prevention strategies should be tailored to different developmental stages and injury causes.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- Childhood injuries represent a significant public health concern globally.
- Understanding injury patterns is crucial for developing effective prevention strategies.
- Hong Kong's specific injury profile requires detailed investigation.
Purpose of the Study:
- To analyze the characteristics of 7813 childhood injuries in Shatin, Hong Kong.
- To examine the developmental specificity of external injury causes.
- To compare Hong Kong's childhood injury data with international statistics.
Main Methods:
- Analysis of attendance records from the Prince of Wales Hospital's accident and emergency department.
- Inclusion of children aged 0-15 years.
- Data collection on injury details (ICD-9 E and N codes, AIS, ISS), age, and gender.
Main Results:
- Males (65.7%) and fall-related injuries (44.2%) were most common; contusions (34.6%) were the prevailing injury nature.
- Correspondence analysis revealed age-specific external causes: 0-1 year olds (falls, poisoning, scalds, machinery) and 12-15 year olds (motor, animal, cuts/piercings).
- Hong Kong data showed more falls but fewer poisonings and burns than international comparisons.
Conclusions:
- The childhood injury profile in Hong Kong is characterized by a high proportion of falls and a low proportion of poisonings and burns.
- Developmentally specific prevention strategies are recommended based on age-related external causes of injury.
- Targeted interventions are needed to address the unique injury risks across different childhood age groups.
Objectives:
This study describes 7813 childhood injuries in Shatin, Hong Kong. Supplementary analyses include developmental specificity of external causes and comparison with international childhood injury data.
Methods:
Children aged 0-15 attending the accident and emergency (A&E) department of the Prince of Wales Hospital in Hong Kong were recruited for the study. Attendance records of participants from the A&E department were analyzed. Details concerning the injury, including the International Classification of Diseases, ninth revision, external cause of injury (E code), nature of injury (N code), abbreviated injury scale, and injury severity scale constitute core measurements, along with participants' age, gender, and respective A&E procedural data.
Results:
Males (65.7%) and fall related injuries (44.2%) predominate, while contusion (34.6%) is the prevailing nature of injury. Two age external cause dimensions are derived from a correspondence analysis. Children 0-1 years old are associated with falls, poisoning, scalds, and machinery related injury. Adolescents aged 12-15 are associated with motor related injury, animal related injury, and cuts/piercings. In comparison with international data, unintentional child injuries in Hong Kong comprised more falls but fewer poisonings and burns.
Conclusion:
A large proportion of falls, along with low proportion of poisonings and burns, are characteristics of childhood injury profile in Hong Kong. From the results of age external cause correspondence analysis, prevention strategies for different external cause should be developmentally specific.
