Effect of MyopiaEd Messaging on Improving Eye-use Behavior and Myopia Control Among Primary School Students in China: A Randomized Controlled Trial

Not Applicable
Not yet recruiting
Conditions
Myopia
Registration Number
NCT07211893
Lead Sponsor
Zhongshan Ophthalmic Center, Sun Yat-sen University
Brief Summary

Myopia represents a significant global public health challenge, with China experiencing particularly high myopia prevalence among children and adolescents. The World Health Organization (WHO) acknowledges the critical role of health education in eye care and has collaborated with the International Telecommunication Union (ITU) to launch the Be He@lthy, Be Mobile (BHBM) initiative, which includes MyopiaEd-a mobile health project specifically designed to address myopia. Developed in partnership with international experts and informed by evidence-based guidelines, MyopiaEd provides standardized, scientifically validated content for effective myopia control. The MyopiaEd library has been translated and adapted by the Zhongshan Ophthalmic Center for use in China. Therefore, we aim to investigate whether the Chinese version of MyopiaEd can improve eye care behaviors among primary school students and enhance parental knowledge regarding myopia prevention and control in China.

Primary Outcome Measures
NameTimeMethod
The proportion of children having improved eye-use behaviors after 1 year.12 months

Children are considered to have improved behaviors if they meet three or more of the following criteria after 12 months:

Outdoor Time: Increase of ≥ 30 minutes for those initially \< 2 hours; maintain ≥ 2 hours for those initially ≥ 2 hours.

Near Work Time: Reduce ≥ 30 minutes for those initially ≥ 1 hour; maintain \< 1 hour for those initially \< 1 hour.

Screen Time: Reduce ≥ 30 minutes for those initially ≥ 1 hour; maintain \< 1 hour for those initially \< 1 hour.

Eye Exam Frequency: Increase of ≥ 1 exam for those with \< 2 exams initially; maintain ≥ 2 for those with ≥ 2 exams.

Sitting Posture: Increase of ≥ 1 point for those with ≤ 3; maintain ≥ 4 for those with ≥ 4.

Resting Behavior During Near Work: Increase of ≥ 1 point for those with ≤ 3; maintain ≥ 4 for those with ≥ 4.

Spectacle-Wearing: Children not wearing glasses begin after 12 months. Daily Spectacle Wear for Myopic Children: Increase of ≥ 1 hour for those wearing ≤ 8 hours; maintain \> 8 hours for those wearing \> 8 hour.

Secondary Outcome Measures
NameTimeMethod
Difference in the change of spherical equivalence between baseline and 12 months in the two groups12 months

Difference in the change of spherical equivalence between baseline and 12 months in the two groups. Spherical equivalence is calculated as sphere plus half of cylindrical power, as assessed by auto-refraction.

Change in myopia-related knowledge score of students' guardians between baseline and 12 months12 months

Change in myopia-related knowledge score of students' guardians between baseline and 12 months, assessed via questionnaire

Difference in incidence of myopia between the two groups after 12 months12 months
