THE EFFECTIVENESS OF REFRACTION INTERVENTIONS IN STUDENTS IN JUNIOR HIGH SCHOOLS IN DANANG
Objective: The study aimed to evaluate the results of interventions refraction in junior high school students in Da Nang. Methods: A community intervention study was designed in comparison with the control group.The interventions based on junior high schools in Da Nang were implemented in two years in order to prevent school refraction and focused on 3 groups of basic solutions which were based on such evidence like positive communicative interventions to change behaviors, applying learner centered problem solving approach LEPSA, improving the school’s sanitary conditions and supporting medical services using proper techniques. Results: The intervention models have achieved the results as follows: The refraction rate of the intervention group decreased by 8.6% (from 37.0% to 28.4%). The refraction rate of the non-intervention group increased 17.7% (from 39.7% to 57.4%). Performance Index reached 67.8%. Conclusions: Intervention models based on community involvement and having community attendance through stable solutions such as positive communicative interventions that combined with the solutions to improve school-based sanitary conditions on the mobilization of schools and families as well as proper technical supports in medinice that are suitable with the community have helped reduce the refraction prevalence of students. Key words: refractive errors, the effectiveness of refraction interventions.
