Background:
Childhood injury is a major public health issue in China, yet detailed provincial-level data are limited. This study aimed to investigate the epidemiology, determinants, and burden of injuries among children aged 0-17 years in Henan Province.
Methods:
A population-based cross-sectional survey was conducted from June 2022 to May 2023 using a multi-stage stratified cluster random sampling design. Data were collected via face-to-face questionnaires from guardians of 9,859 children aged 0-17 years. Complex sampling weights were applied, and Rao-Scott χ 2 tests and logistic regression were used for analysis.
Results:
The overall injury incidence rate was 6.88%, with a significantly higher rate in boys (8.23%) than in girls (5.32%). Multivariable logistic regression indicated that boys had higher odds of injury compared to girls (OR = 1.58, 95% CI: 1.27-1.97), and day students (returning home daily) had higher odds compared to children not enrolled in school (OR = 1.69, 95% CI: 1.16-2.46). Children under the care of their grandparents (OR = 1.33, 95%CI: 1.06-1.67) had a higher injury risk compared to those cared for by their mother. Critically, although a caregiver was present at the time of injury in 54.17% of incidents, effective supervision was lacking in 67.71% of these cases. Falls were the leading cause (53.90% of all incidents) of injury. The home was the most common injury location (41.73%), and leisure activities were the most frequent circumstance (59.30%). The most common injury type was contusion/abrasion (37.47%); the lower extremities were the most frequently injured body site (37.70%). The mean hospital stay was 18 days, with an average of 9 missed days, and the mean cost per injury was 2,713 Chinese Yuan, with road traffic injuries incurring the highest costs.
Conclusion:
This study provides key evidence for childhood injury prevention in Henan Province. Priorities include strengthening supervision (especially at home during leisure), tailored interventions for high-risk groups (boys, day students, grandparent-care children), and focusing on falls (high frequency) and road traffic injuries (high cost). Implementing these strategies is essential to reduce the burden of preventable childhood injuries.
