1Epidemiology Section, Jiangmen Sanitary and Anti-epidemic Station, Jiangmen, Guangdong 529050, China.
Objective:
To explore the intervention measures for prevention and control of injuries and evaluation for their effectiveness in students of middle and primary schools.
Methods:
Effectiveness of intervention was evaluated by comparison of incidence of injury before and after intervention in 3,896 students of nine middle and primary schools and comparison with a non-intervention group in 651 students of four primary schools in Jiangmen City, Guangdong Province during January to December, 1999.
Results:
Incidence of injury dropped to 11.78% after intervention from 50.55% before intervention in the intervention group, with 76.70% of reduction. Proportion of severe injury dropped to 0.65% after intervention from 7.84% before intervention. Incidence of multiple injuries dropped to 3.15% from 19.16%, with 83.56% of reduction. But, in the control group, incidence of injury dropped to 49.00% from 52.67%, with 6.97% of reduction only, with a ratio of reduction of intervention to control of 11.02% and a ratio of cost to benefit of 1:13.9.
Conclusion:
Intervention measures focusing on health promotion can prevent and control the occurrence of injury in students of middle and primary schools cost-effectively.
