摘要
[目的]探讨大学生视屏显示终端(VDT)操作视觉健康管理效果,建立大学生VDT操作视觉健康管理模式。[方法]选择浙江省某高校大一年级学生106名,随机分为干预组和对照组,每组53人。干预组进行为期6个月的信息收集、风险评估和实施干预三步骤的VDT操作视觉健康管理,对照组不施加任何干预措施。比较干预前后两组VDT操作视觉症状的检出率、干预组VDT操作用眼生活行为方式危险因素的发生率。[结果]干预前,干预组与对照组VDT视觉症状检出率差异无统计学意义(P>0.05)。干预组在实施6个月的健康管理后各项VDT视觉症状检出率较对照组均明显下降(P<0.01),VDT视觉症状检出率、VDT操作用眼生活行为方式危险因素发生率均较干预前明显下降(P<0.05或0.01)。干预组视觉健康管理总有效率为84.91%。[结论]大学生VDT操作视觉健康管理对改善大学生VDT操作视觉健康问题效果显著。
[ Objective ] To assess the effect of a visual health management intervention program on visual display terminal （VDT） operation behavior of university students, and to establish a management model for VDT operation among this population. [ Methods ] Totally 106 freshmen were chosen from a university in Zhejiang province and divided into an intervention group and a control group by random assignment, each with 53 students. The intervention group received a six-month-visual-health-management program on VDT operation which went through three steps, i.e. information collection, risk assessment, and implementation of intervention; while no intervention measure was given to the control group. The detection rates of VDT related visual symptoms and the prevalence of behavioral risk factors for VDT operation and lifestyle before and after the intervention were compared. [ Results ] At baseline, no statistical difference in the detection rates of visual symptoms was found between the two groups （P 〉 0.05）; but after the six-month program, the detection rates of visual symptoms in the intervention group declined obviously compared with the control group （P 〈 0.01） and also with the baseline values （P 〈 0.01）. The prevalence rates of behavioral risk factors for VDT operation and lifestyle significantly decreased after the intervention （P〈0.05 or 0.01）. The total effectiveness rate of the program reached 84.91%. [ Conclusion ] The visual health management intervention program for VDT operation demonstrates a remarkable effect on improving university students＇ VDT operation related visual health.
