Objective:
To describe the rate and pattern of unintentional school injuries among primary and middle school students and to explore the major risk factors involved.
Study Design:
A cross-sectional survey of more than 10,000 students attending 6 primary and 4 middle schools selected randomly from all schools in Maanshan City of Anhui Province in eastern China was conducted to collect information on school injuries occurring in the 12-month period before the survey. Rate ratios for risk factors were estimated using the negative binomial regression analysis.
Results:
The annual person-based school injury rate was 5.22 (95% CI: 3.90-6.53) percent. The annual event-based injury rate was 5.40 (95% CI: 4.04-6.76) per 100 students. Most injuries in school were relatively mild and only 1.53% (9/590) of the episodes resulted in hospitalization. The most frequent injures were falls (73%), and the most commonly injured sites were the upper limbs (46%). Male sex, primary school grades, poor health status, poor ability to concentrate, bad risk-taking behavior and high study-related stress were important risk factors.
Conclusion:
This study provided useful baseline information on school injuries in China and identified important risk factors that would be important in planning prevention strategies.
