早期干预在校大学生视屏终端性眼病效果评价

Early Intervention Effect on Visual Display Terminal(VDT) Among Undergraduates

目的探讨在校大学生视屏终端性眼病(VDT综合征)早期干预的效果,为VDT的防治提供依据。方法选择丽水学院医学院大一、大二年级在校学生200名,随机分为2组,每组100人。干预组进行为期5个月针对VDT综合征的早期干预,对照组学生不进行干预,比较干预前后2组学生VDT综合征的发生情况。结果干预前2组学生VDT综合征发生率差异无统计学意义。经过5个月的早期干预后,干预组VDT综合征发生率为10.0%,较干预前的36.0%显著下降,差异有统计学意义(P<0.01)。结论早期干预对预防在校大学生VDT综合征的发生具有显著效果。

Objective To explore the effect of lowing the incidence rate of visual display terminal（VDT） among undergraduates by early prevention, and to provide evidence for the prevention. Methods Two hundred undergraduates of grade one and two were chosen from Medical School of Lisbui College. They were divided into the intervention group and control group at random, each with 100. The intervention group received five months＇ early intervention against VDT, while no intervention was given to the control group. The prevalence rate was compared with each other between the two groups. Results Before the intervention, no statistical significance of VDT prevalence was found between the two groups. After the five months＇ early intervention, the incidence rate of VDT of the intervention group were 10.0%, which was significantly decreased before early intervention（36.0%, P 〈0.01 ）. Conclusion Early intervention has a remarkable effect on the prevention of VDT.
