Assessment of the level of exposure to work-related musculoskeletal disorders (WMSDs) risk factors can be an appropriate basis for planning and implementing an interventional ergonomics program in the workplace. This study was conducted among workers of an Iranian sugar-producing factory to determine WMSD prevalence rate among production workers and to assess the level of exposure to WMSD risks.
In total, 116 workers were randomly selected from production workshops and included in the study. The Nordic musculoskeletal questionnaire was used to study prevalence of WMSDs and a quick exposure check (QEC) was used to assess physical exposure to risks. Required data were videotaped.
Most workers (87.1%) suffered from some kind of MSD symptoms during the 12 months prior to the study. The highest prevalence was reported in knees (58.6%) and the lower back (54.3%). In 99.1% of the workers, the level exposure to MSD risks established with QEC was high and very high. Awkward postures, manual material handling, and long hours of standing were the major ergonomics problems.
There was a high rate of WMSDs in this factory. The level of exposure to WMSD risk factors was high and corrective measures for reducing risk level were essential.
评估与工作相关的肌肉骨骼疾病（WMSD）危险因素的暴露水平，可以为在工作场所规划和实施干预性人体工程学计划提供适当的依据。本研究在一家伊朗制糖厂的工人中进行，旨在确定生产工人中 WMSD 的患病率，并评估接触 WMSD 风险的程度。
总共从生产车间随机选择了 116 名工人，并将其纳入研究。使用北欧肌肉骨骼问卷研究 WMSD 的患病率，使用快速暴露检查（QEC）评估身体对风险的暴露程度。所需数据被录像。
在研究前的 12 个月内，大多数工人（87.1%）患有某种 MSD 症状。膝盖（58.6%）和下背部（54.3%）的患病率最高。在 99.1%的工人中，使用 QEC 确定的 MSD 风险暴露水平较高且很高。不舒适的姿势、手动搬运物料和长时间站立是主要的人体工程学问题。
该工厂 WMSD 的发病率很高。接触 WMSD 危险因素的程度很高，必须采取纠正措施来降低风险水平。
