影响青少年近视的因素分析

Analysis of influence factors of adolescent myopia

摘要:

目的：探讨引起青少年视力下降的主要影响因素，以便采取有效的预防或及时干预。

方法：对11所学校连续6a的2 050名体检学生的体检结果进行总结分析，就引起近视的常见原因对比、统计，采用Logistic回归分析，从中选出较明显的致近视因素。

结果：在诸多致青少年近视的因素中，作业过多及光源闪烁的系数分别为1.132和1.254，危险度为3.590和3.681，逐步回归模型结果显示作业过多分值为(OR=2.054)、光源闪烁(OR=2.036)。

结论：作业过多及光源闪烁的持续存在是引起青少年视力下降的主要影响因素。

Abstract:

AIM: To explore the major factors causing adolescent eyesight decline, so as to take effective prevention or timely intervention.

METHODS: The myopic teenagers(n=2 050)were followed up for 6 consecutive years. The common causes of myopia were compared and the statistics were processed using logistic regression analysis, then the factors more obvious in inducing myopia were selected.

RESULTS: In many factors causing adolescent myopia, operating coefficient of excessive homework and scintillating light source were respectively 1.132 and 1.254. Risk of the two factors were 3.590 and 3.681. Result of the stepwise regression model was(OR=2.054)for excessive homework and(OR=2.036)for scintilating light source.

CONCLUSION: The excessive homework and persistent flickering light source are the main influence factors causing adolescent myopia.
