Background Workers in the brick manufacturing industries require to carry heavy loads, do repetitive work and remain in awkward postures for extended periods of time. These activities may cause them to develop work-related musculoskeletal symptoms and disorders. Objective To investigate the epidemiology of musculoskeletal symptoms and disorders among brick manufacturing workers as well as similar exposure groups among brick kiln workers. Method An analytical cross-sectional study was conducted during February - March 2015 in the Kathmandu Valley. From 16 brick kilns, 400 interviewees involving green brick molding, green brick stacking/carrying, red brick loading/carrying, coal crushing/ carrying and firing were recruited. An unmatched equal size of reference group of grocery workers was maintained for comparison. Prevalence of all musculoskeletal symptoms and disorders were computed and compared among brick workers and grocery workers as well as similar exposure groups among brick kiln workers. Result The musculoskeletal symptoms and disorders were prevalent in 90.5% of the exposed and 82.2% of the reference group. Brick kiln workers were about two times more likely to experience musculoskeletal symptoms and disorders compared to the reference group. When the associations among similar exposure groups were evaluated, there were significantly high prevalence of musculoskeletal symptoms and disorders among green brick molders, red brick loaders/carriers and coal crushers/ carriers in comparison to firemen. Conclusion This study showed a high prevalence of musculoskeletal symptoms and disorders among brick kilns workers. Among all similar exposure groups, coal crushing/carrying task significantly elevated with all types of musculoskeletal symptoms and disorders.
背景 砖制造业的工人需要搬运重物、从事重复性工作并长时间保持不良姿势。这些活动可能导致他们出现与工作相关的肌肉骨骼症状和疾病。目的 调查砖制造业工人以及砖窑工人中类似暴露组的肌肉骨骼症状和疾病的流行病学情况。方法 2015年2月至3月在加德满都谷地进行了一项分析性横断面研究。从16个砖窑中招募了400名受访者，他们涉及青砖成型、青砖堆放/搬运、红砖装载/搬运、煤炭粉碎/搬运和烧制工作。维持一个规模相等的杂货店工人对照组进行比较。计算并比较砖窑工人和杂货店工人以及砖窑工人中类似暴露组的所有肌肉骨骼症状和疾病的患病率。结果 暴露组中90.5%的人以及对照组中82.2%的人存在肌肉骨骼症状和疾病。与对照组相比，砖窑工人出现肌肉骨骼症状和疾病的可能性约为两倍。在评估类似暴露组之间的关联时，与烧窑工人相比，青砖成型工、红砖装载/搬运工和煤炭粉碎/搬运工中肌肉骨骼症状和疾病的患病率显著较高。结论 本研究表明砖窑工人中肌肉骨骼症状和疾病的患病率很高。在所有类似暴露组中，煤炭粉碎/搬运任务与所有类型的肌肉骨骼症状和疾病显著相关。
