Modifiable behavioral factors associated with myopia among school-aged children.
Keeping screens 30+ cm from the eyes was linked to lower odds of myopia in kids.
Modifiable behavioral factors associated with myopia among school-aged children.
This study aimed to examine behavioral factors associated with myopia among school-aged children.
School physical examination records and parent-administered questionnaire data were collected from nine schools in Haizhu District, Guangzhou.
Children with eye-to-screen distance of 30 cm or more had lower odds of nearsightedness.
After adjustment for demographic, familial, anthropometric, and parental educational covariates, homework time 2-4 h per day was associated with higher odds of myopia [odds ratio (OR) = 1.24; 95% confidence interval (CI) = 1.07-1.44, P = .004].
Several modifiable behavioral factors were associated with myopia among school-aged children.
Maintaining an appropriate near-work distance, limiting prolonged after-school homework or reading time, and increasing outdoor activity may provide practical targets for school- and family-based myopia prevention.
Key messages What is already known on this topic: Previous studies have shown that prolonged near work and limited outdoor time are associated with myopia in children.
