This study has been conducted in Sénégal, where Video Display Terminals (VDT) constitute for more than one decade an occupational tool for thousands of workers. Its objectives were to identify symptoms on VDT operators and to state the hazards related to its use. The methodology consists of a Cross sectional study using questionnaire based on the model proposed by the National Research and Security Institute of Paris (INRS). The study target was workers in 4 industries of the capital city Dakar, where VDT have been widely used. 152 persons have been questioned; 50.7% were male. 82.9% of complaints are related to musculosqueletic disorders mainly located in the low back, the neck, and the shoulders. Ergonomics problems appears to be the main cause of these symptoms; no replacement medical examination was performed and as the result, 23.6% did benefit from an ophthalmologic check-up in the 2 years following the use of VDT. Ergonomic evaluation of the working environment as well as medical surveillance are necessary to prevent occurrence of symptoms on VDT users in our country.
本研究在塞内加尔进行，在那里视频显示终端（VDT）十多年来一直是数千名工人的职业工具。其目的是识别VDT操作人员的症状，并阐述与使用VDT相关的危害。该方法包括一项横断面研究，使用基于巴黎国家研究与安全研究所（INRS）提出的模型的问卷。研究对象是首都达喀尔4个行业中广泛使用VDT的工人。共对152人进行了询问；其中50.7%为男性。82.9%的投诉与肌肉骨骼疾病有关，主要位于下背部、颈部和肩部。人体工程学问题似乎是这些症状的主要原因；未进行替代医学检查，因此，在使用VDT后的两年内，23.6%的人受益于眼科检查。对工作环境进行人体工程学评估以及进行医学监测对于预防我国VDT使用者出现症状是必要的。
