Musculoskeletal disorders in welders may influence their health-related quality of life. However, few studies have addressed this issue and their results were inconclusive. This study investigates whether there are musculoskeletal disorders with a higher incidence in welders compared to non-welders, and whether these disorders lead to an increase in bodily pain which in turn decreases their health-related quality of life. analyses of statistical power were conducted to determine the sample size needed to find medium to large statistical effects, for a 0.05 alpha, and critical sampling, combined with snowball sampling, was carried out. The study was cross-sectional, and participants were asked to respond to a survey using validated instruments ( = 40, = 42). As expected, a higher incidence of symptoms of musculoskeletal disorders in the cervical, dorsal, lumbar, and wrists and hands was found in welders in comparison to non-welders. Furthermore, the presence of musculoskeletal disorders, particularly in the lumbar area, was related to an increased bodily pain and decreased health-related quality of life. Welders are exposed to a higher incidence of musculoskeletal disorders that decrease their quality of life. It is essential to increase the awareness of welders, organizations, and regulatory institutions toward this issue in order to motivate the development and implementation of prevention strategies. The need for primary and secondary prevention-type strategies, which have already proven their effectiveness in the context of welding, is highlighted.
焊工的肌肉骨骼疾病可能会影响他们的健康相关生活质量。然而，很少有研究涉及这个问题，其结果也不一致。本研究旨在调查焊工是否比非焊工更容易出现肌肉骨骼疾病，以及这些疾病是否会导致身体疼痛增加，从而降低他们的健康相关生活质量。为了找到具有中等至较大统计效果的样本量，进行了统计功效分析，设定了 0.05 的 alpha 水平和临界抽样，结合雪球抽样进行了分析。该研究为横断面研究，要求参与者使用经过验证的工具（n = 40，n = 42）对调查进行回应。不出所料，与非焊工相比，焊工的颈部、背部、腰部、手腕和手部的肌肉骨骼疾病症状发生率更高。此外，肌肉骨骼疾病的存在，特别是在腰部，与身体疼痛增加和健康相关生活质量下降有关。焊工更容易出现肌肉骨骼疾病，从而降低他们的生活质量。提高焊工、组织和监管机构对这一问题的认识至关重要，以便激励制定和实施预防策略。突出强调了初级和二级预防型策略的必要性，这些策略在焊接环境中已经证明了其有效性。
