title: [A comprehensive evaluation on intervention measures for injuries in primary and middle school students].
abstract: 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.
  
  
  CONCLUSIONS
  Intervention measures focusing on health promotion can prevent and control the occurrence of injury in students of middle and primary schools cost-effectively.
