Globally, computer is one of the common office tools used in various institutions. Using computer for prolonged time led to the users at greater health risk of computer vision syndrome (CVS). Computer vision syndrome is the leading occupational health problem of the twenty-first century. About 70 percent of computer users are suffered from CVS. Besides the health problems, CVS causes inefficiency at workplace and deteriorate quality of work. The problem of CVS and its risk factors are not well known in Ethiopia.
A cross-sectional study was conducted to assess the prevalence of CVS and associated factors among computer user government employees in Debre Tabor town from February to March, 2016. Multistage random sampling method was applied to select 607 study participants, and the data were collected by using a structured questionnaire. Computer vision syndrome was measured by self-reported method. Bivariate and multivariable binary logistic regression analyses were performed using SPSS version 20. Significance level was obtained at 95% CI and value < 0.05.
The prevalence of CVS was 422 (69.5%) with 95% CI of 65.60, 73.0%. Blurred vision, eyestrain, and eye irritation were the commonest reported symptoms of CVS with proportion of 62.60%, 47.63%, and 47.40%, respectively. Occupation: officer (adjusted odds ratio (AOR) = 4.74) and secretary (AOR = 9.17), daily computer usage (AOR: 2.29), and preexisting eye disease (AOR = 3.19) were risk factors for CVS. However, computer users with high payment, who took regular health break, and with good knowledge on computer safety measures were less impacted by CVS.
The prevalence of computer vision syndrome was found to be higher in Debre Tabor town. Monthly income, occupation, daily computer usage, regular health break, knowledge, and preexisting eye disease were predictor variables for CVS. Optimizing exposure time, improving awareness on safety measures, and management support are important to tackle CVS.
在全球范围内，计算机是各类机构常用的办公工具之一。长时间使用计算机使用户面临更高的患计算机视觉综合征（CVS）的健康风险。计算机视觉综合征是21世纪主要的职业健康问题。约70%的计算机用户患有CVS。除了健康问题，CVS还会导致工作场所效率低下和工作质量下降。在埃塞俄比亚，CVS问题及其风险因素尚不为人所知。
2016年2月至3月，在德布雷塔博尔镇对政府部门计算机用户雇员进行了一项横断面研究，以评估CVS的患病率及相关因素。采用多阶段随机抽样方法选取607名研究参与者，并使用结构化问卷收集数据。通过自我报告法测量计算机视觉综合征。使用SPSS 20版进行二元和多变量二元逻辑回归分析。显著性水平在95%置信区间且P值<0.05时获得。
CVS的患病率为422（69.5%），95%置信区间为65.60，73.0%。视力模糊、眼睛疲劳和眼睛刺激是CVS最常见的报告症状，比例分别为62.60%、47.63%和47.40%。职业：官员（调整比值比（AOR）=4.74）和秘书（AOR=9.17）、每日计算机使用时间（AOR：2.29）以及既往眼部疾病（AOR=3.19）是CVS的风险因素。然而，高收入、定期进行健康休息且对计算机安全措施有良好认知的计算机用户受CVS的影响较小。
德布雷塔博尔镇计算机视觉综合征的患病率较高。月收入、职业、每日计算机使用时间、定期健康休息、认知以及既往眼部疾病是CVS的预测变量。优化接触时间、提高对安全措施的认识以及管理支持对于应对CVS至关重要。
