西安市高校学生视频显示终端综合征现状及影响因素

探究西安市高校学生视频显示终端(video display terminal,VDT)综合征影响因素,为开展综合防治提供理论依据.方法 采用多阶段分层整群抽样法,随机选取西安市1 491名在校大学生进行VDT综合征相关问卷调查,应用因子分析和多因素Logistic回归分析探讨VDT综合征罹患的可能影响因素.结果 高校学生VDT综合征检出率为73.6%.自我报告的VDT操作相关健康问题中,眼干、眼痛、眼胀、视力下降、视物模糊等眼部症状的检出率最高,分别为69.4%,62.6%,62.4%,59.0%,56.1%.进一步单因素和多因素Logistic回归分析结果显示,视力异常、饮食习惯差、身体健康状况欠佳、不良VDT操作习惯可增加VDT综合征的发生风险[OR值(95%CI=1.14(1.011.29),1.15(1.011.30),1.51(1.331.71),1.18(1.041.33)]);良好的睡眠精神状态、适宜的工作环境条件与VDT综合征罹患危险性的降低有关[OR值(95%CI=0.68(0.600.77),0.67(0.590.76).结论 高校学生VDT综合征检出率较高,眼部健康、饮食习惯、睡眠精神状态、环境、个人体质及计算机使用习惯等多种因素共同参与其发展,应加强相关健康教育.

Analysis of the influencing factors of video display terminal syndrome among college students in Xi'an

Objective To investigate the related influencing factors of video display terminal (VDT) syndrome risk among college students in Xi'an, thereby providing theoretical evidence for its comprehensive prevention and treatment.Methods Totally1 491 subjects, randomly selected from Xi'an by multi-stage cluster sampling method, were surveyed in the questionnaire investigation consisting of lifestyle, dietary assessment and symptoms of VDT.Multivariate unconditional logistic regression models was used to evaluate the association between dietary patterns and VDT symptom risk.Results Among college students, the overall prevalence of VDT syndrome was 73.6%.Eye symptoms such as dry eye, eye pain, eye swelling, and vision loss (69.4%, 62.6%, 62.4%, 59.0%, 56.1%) were the highest among self-reported health problems related to VDT operations.Multivariate logistic regression analysis showed that abnormal vision, bad eating habits, poor physical status, poor VDT operation habits were significantly associated with a higher risk of VDT syndrome, the OR values (95%CI) were as follows: 1.14 (1.01, 1.29), 1.15 (1.01, 1.30), 1.51 (1.33, 1.71) and 1.18 (1.04, 1.33).In addition, the results of multivariable analysis also supported a slightly protective effect of good sleep and mental state and suitable working conditions, with the corresponding OR values (95% CI) being 0.68 (0.60, 0.77) and 0.67 (0.59, 0.76).Conclusion The prevalence of VDT syndrome is fairly high among college students.Ocular factors, dietary habits, sleep and mental state, environmental conditions, physical fitness and habit of computer usage are all involved in the development of VDT syndrome.Relevant health education should be strengthened to effectively curb the occurrence of VDT syndrome.
