PURPOSE: The Recess Outside Classroom (ROC711) intervention program initiated and supported by Taiwan Health Promotion Administration, aimed to investigate the effectiveness of increasing outdoor time in myopia prevention.

METHODS: This was a cluster randomized controlled trial on myopia prevention. Elementary schools in Taiwan were stratified into 4 areas in northern, middle, southern and western. Within each area, schools were randomly selected as intervention or control group. In the intervention group, the grade 1 schoolchildren were encouraged to go outdoors during the recess time and parents were also suggested to have more outdoor activities with their children. Outcome measurements included eye examination, cycloplegic refraction, wearing light meter recorder and questionnaire.

RESULTS: A total of 16 schools completed the 1-year ROC711 program. There were 7 schools (n=285) in the intervention group and 9 schools (n=431) in the control group. The intervention group spent 1 hour more than the control group did in the weekdays and weekend respectively, and had statistical significant less myopic shift than the control group (0.09D, 95%CI=0.02~0.15, p=0.008). In addition, it also had statistically significant less myopic shift and less axial length elongation than the control group (0.12D and 0.04mm, p = 0.001 and 0.016 respectively) with adjustment of covariates.

CONCLUSION: The results of this ROC711 intervention program suggest that 1 year course of this program could have the effect to reduce myopia progression and axial length elongation. The implementation of this program can be promoted for myopia prevention in Taiwan elementary school system.
