| الوصف: | Background: This study aimed to explore the distribution of spherical equivalent (SE) and its association with age, BMI, sex in a non-myopic Chinese children population aged 6 to 12 years. Alarming threshold values were proposed to predict the future onset of myopia, and relationship between alert values and myopia related factors was explored.Methods: Demographic information was gathered from an ophthalmic examination taken by a total of 6362 students. SE value was obtained by the application of autorefractors. Some of the parents filled in a questionnaire of factors related to myopia among children.Results: Among 6362 students, 3900 (61.3%) were non-myopic. The prevalence of myopia is 38.0% for boys and 39.5% for girls. The average SE values were 0.50±0.70 D for boys and 0.60±0.80 D for girls. The mean SE values decreased with age, and the value of height and BMI took on a stable trend. Alarming threshold values for myopia were set as follows: for children aged 6 years, 0.40-0.60 D for boys and 0.80-1.00 D for girls; for children aged 7 years, 0.40-0.60 D for boys and 0.30-0.50 D for girls; for children aged 8 years, 0.20-0.40 D for boys and 0.30-0.50D for girls; for children aged 9 years, 0.20-0.40 D for boys and 0.30-0.40D for girls; for children aged 10 years, 0.10-0.30 D for boys and 0.30D for girls; for children aged 11 years, 0.10-0.30 D for boys and -0.30-0.30 D for girls; for children aged 12, -0.10-0.10 D for boys and -0.30-0.10 D for girls. Paternal myopia (OR: 1.22, 95%CI: 1.01-1.48), near work on weekends (OR: 2.56, 95%CI: 1.17-5.61), and outdoor activities (OR: 0.68, 95%CI: 0.54-0.86) had an impact on non-myopic students with myopic alarming threshold.Conclusion: This study described a distribution of refraction for non-myopic students in Jiangsu Province, China. A series of alert values were proposed to provide early warning reference for Chinese children aged 6 to 12 years. Paternal myopia, near work, and outdoor activities had an impact on non-myopic students with myopic alert threshold, and sensitive continuous data concerning risk factors mentioned above should be explored to be used as an early alert value in the future. |
