Abstract

Objective To analyze the mechanism of the influencing factors of myopia for junior high school students in China. Methods Based on the follow-up to 7 119 students in the 3 waves of questionnaire survey of the Chinese Education Panel Survey in junior high school stage, and the variables on students' myopia status, myopia influencing factors, and two kinds of risk behaviors of myopia including near visual activities and outdoor activities, the mediation effects of the myopia risk behaviors were tested by Logistic regression model. Results The myopia prevalence of 9th graders before junior high school graduation was 66.36%. Time on writing homework significantly increased the risk of myopia, the odds ratio (OR) was 1.17, the 95% confidence interval (CI) was 1.13-1.21, and the time on outdoor sports significantly decreased the risk of myopia (OR=0.80, 95% CI: 0.75-0.86). Before and after including the risk behaviors into the model, the myopia risk OR(95% CI) of female centralized from 1.84(1.66-2.04) to 1.69(1.51-1.88), the myopia risk OR(95% CI) of urban students'centralized from 1.19(1.03-1.37) to 1.16(1.00-1.34), the myopia risk OR(95% CI) of only children'centralized from 1.20(1.06-1.36) to 1.18(1.04-1.33). With reference to not myopic for both parents, the myopia risk OR(95% CI) of students having one myopic parent centralized from 2.47(2.12-2.88) to 2.44(2.09-2.85), the myopia risk OR(95% CI) of students having parent without myopic centralized from 4.25(3.09-5.86) to 4.13(3.00-5.69). Conclusions Gender, urban and rural, only child, and myopic parents are influencing factors of myopia. These factors have effects on myopia via two kinds of risk behaviors including outdoor activities and near visual activities.
- Myopia,
- Near visual activity,
- Outdoor activity,
- Mediation effect
