Hand screen-printing (HSP) plays a predominant role in textile industries in developing countries. Workers from HSP industry were mostly affected by musculoskeletal injury due to monotonous, and prolonged work nature and poor workplace environment.
The present study aims to investigate the prevalence of work-related musculoskeletal disorder (MSD) symptoms and risk factors associated among the HSP industry workers.
Cochran's sample size for categorical data was used to select 385 HSP workers of 1000 samples from various provinces of Tamil Nadu, INDIA. Modified Nordic based questionnaire was used to assess the musculoskeletal injuries and risk factors among HSP workers.
The statistical analysis revealed that 62.5% workers are prone to MSD symptoms with lower back (75.1%), shoulder (66.2%), knees (58.7%), and ankle/feet (55.6%). Age, experience, marital status, stress in the job were the risk factors which significantly (p < 0.05) associated with the reported MSDs. Further, this study result infers that the subjects with higher age and experience are exposed higher levels of MSD prevalence of 85.5% and 92.0% respectively in past 12 months than other groups. Among the different work categories in HSP task, the workers reported with the maximum discomfort during printing work (63.1%) with Odds ratio as 10.38 and 95% CI is 6.18-17.4. than the material handling and drying task.
Study results infer that HSP workers are prone to lower back and shoulder pain followed by knees and ankle feet regions. Socio-demographic factors, awkward posture and repetitive movements contribute to cause MSD among hand screen-printing workers.
手工丝网印刷（HSP）在发展中国家的纺织工业中起着主导作用。由于工作性质单调、工作时间长以及工作环境恶劣，HSP行业的工人大多受到肌肉骨骼损伤的影响。
本研究旨在调查HSP行业工人中与工作相关的肌肉骨骼疾病（MSD）症状的患病率及其相关危险因素。
采用Cochran分类数据样本量计算方法，从印度泰米尔纳德邦各省份的1000名样本中选取385名HSP工人。使用基于改良北欧问卷评估HSP工人的肌肉骨骼损伤和危险因素。
统计分析显示，62.5%的工人容易出现MSD症状，以下部位较为常见：下背部（75.1%）、肩部（66.2%）、膝盖（58.7%）和脚踝/足部（55.6%）。年龄、工作经验、婚姻状况、工作压力是与报告的MSD显著相关（p<0.05）的危险因素。此外，本研究结果推断，年龄较大和工作经验较丰富的受试者在过去12个月中MSD患病率分别高达85.5%和92.0%，高于其他组。在HSP任务的不同工作类别中，印刷工作期间报告不适程度最高的工人比例为63.1%，优势比为10.38，95%置信区间为6.18 - 17.4，高于物料搬运和干燥任务。
研究结果表明，HSP工人容易出现下背部和肩部疼痛，其次是膝盖和脚踝/足部区域。社会人口统计学因素、不良姿势和重复动作是导致手工丝网印刷工人MSD的原因。
