IT has revolutionized economies throughout the world, more so in India. West Bengal has also got its share of IT boom. But with this, it has brought in the class of human resource of Video Display Terminal workers operators that and along with that can cause a host of occupational problems in them namely musculoskeletal, ocular and psychological systems. The current study had assessed some of the musculoskeletal disorders occurring due to VIDEO DISPLAY TERMINAL use.
An analytical cross-sectional study was done in a Software Company of Sector V, Kolkata, the IT hub of West Bengal. Of all the employees, required sample size of 206 was selected by Simple Random Sampling. After proper permissions and consent, socio-demographic variables were collected by standardized instruments, musculoskeletal morbidity was collected by Nordic questionnaire, and ergonomic practices were obtained by checklists.
90.78% of population showed some form of musculo skeletal symptoms. They were highest in fingers, elbows, wrist, shoulder, upper, while legs and lower back showed low morbidities. Increasing age, female sex, increasing years of work, repetition of work, poorer ergonomic scores all showed to have increased the symptoms. The regionwise ergonomic scores revealed how the poorer scores affected the musculo skeletal systems adversely. Several individual adverse ergonomic practices were also elicited.
The study goes hand to hand with many other studies throughout the world and also in India. However, a much higher morbidity has been found in this study probably due to a symptom based questionnaire. The adverse practices obtained here goes well with other relevant studies.
This study puts occupational health problems of VIDEO DISPLAY TERMINAL users, and upholds the need of future multicentric cohort studies along with implementation of proper measures to ameliorate the effects of this occupational hazard.
信息技术彻底改变了全球经济,在印度更是如此。西孟加拉邦也经历了信息技术的繁荣。但随之而来的是视频显示终端操作人员这一人力资源群体,同时也给他们带来了一系列职业问题,即肌肉骨骼、眼部和心理系统方面的问题。本研究评估了因使用视频显示终端而出现的一些肌肉骨骼疾病。
在西孟加拉邦的信息技术中心加尔各答第五区的一家软件公司进行了一项分析性横断面研究。通过简单随机抽样从所有员工中选取了所需的206个样本。在获得适当许可和同意后,使用标准化工具收集社会人口统计学变量,通过北欧问卷收集肌肉骨骼发病率,并通过清单获取人体工程学实践情况。
90.78%的人群表现出某种形式的肌肉骨骼症状。手指、肘部、手腕、肩部和上肢的症状最为严重,而腿部和下背部的发病率较低。年龄增长、女性、工作年限增加、工作重复性、人体工程学得分较低均显示会加重症状。按地区划分的人体工程学得分揭示了较差的得分如何对肌肉骨骼系统产生不利影响。还发现了一些个体不良的人体工程学实践情况。
本研究与世界其他地区以及印度的许多其他研究结果一致。然而,本研究中发现的发病率要高得多,这可能是由于采用了基于症状的问卷。这里发现的不良实践情况与其他相关研究结果相符。
本研究揭示了视频显示终端用户的职业健康问题,并支持未来进行多中心队列研究以及采取适当措施来减轻这种职业危害影响的必要性。
