Bottling workers maintain awkward postures while performing machine paced repetitive motions in many of their job tasks and therefore are predisposed to work related musculoskeletal discomfort (WMSD). There is a paucity of literature on prevalence and impact of musculoskeletal discomfort among this occupational group.
This study was conducted among Eastern Nigerian beverage factory workers to investigate prevalence of WMSD as a first step towards risk factors investigation and ergonomic future intervention.
A total of 301 workers (8 workstations) completed a modified Nordic Musculoskeletal Questionnaire in this cross sectional survey.
Twelve month prevalence of WMSD was 91.4% and 65.1% had been prevented from doing activity at home or workplace by WMSD in the past 12 months. Shoulder, neck and upper back in that order were the most common complaints. Prevalence of WMSD in body regions were associated with age but not with gender except for neck, upper back, shoulder, and ankle/foot complaints.
WMSDs are very high among beverage bottling workers. Investigation into the prevailing risk factors especially the work posture and work organization/work psychosocial factors for possible risk exposure in these workers is essential for ergonomic intervention towards work injury prevention.
瓶装工人在执行许多工作任务时，需保持笨拙姿势并进行机器节奏的重复动作，因此易患与工作相关的肌肉骨骼不适（WMSD）。关于这一职业群体中肌肉骨骼不适的患病率及影响的文献较少。
本研究在尼日利亚东部饮料厂工人中开展，旨在调查WMSD的患病率，作为危险因素调查及未来进行人体工程学干预的第一步。
在本次横断面调查中，共有301名工人（8个工作站）完成了一份改良的北欧肌肉骨骼问卷。
WMSD的12个月患病率为91.4%，在过去12个月里，65.1%的人因WMSD而无法在家或工作场所进行活动。按顺序排列，肩部、颈部和上背部是最常见的不适部位。身体各部位WMSD的患病率与年龄相关，但除颈部、上背部、肩部和脚踝/足部不适外，与性别无关。
饮料瓶装工人中WMSD的发生率非常高。调查当前的危险因素，尤其是这些工人可能面临风险的工作姿势和工作组织/工作心理社会因素，对于预防工伤的人体工程学干预至关重要。
