The iron and steel industries are among the most dangerous workplaces in the world compared to other manufacturing industries. Workers are exposed to multiple occupational hazards, which predispose them to high risks of both fatal and non-fatal injuries. Currently, the data on the global prevalence and associated risk factors for occupational injuries in the iron and steel industries is fragmented and incomplete. This study was undertaken to address this issue by pooling data relating to the prevalence of occupational injuries and its associated factors among workers in iron and steel industries studies around the world.
The search was conducted systematically using PubMed, HINARI, EMBASE and Google Scholar for published studies in English that reported on occupational injuries and associated risk factors among workers in iron and steel industries. MetaXL version 5.3 software was used in the meta-analysis to estimate the pooled prevalence of occupational injuries and associated risk factors among workers in the iron and steel industries. The study protocol has been registered with PROSPERO, number CRD42022344258.
Of the 447 articles identified, 15 studies from 9 countries met the inclusion criteria. The pooled prevalence estimate of occupational injury was 0.55 (95% CI: 0.15, 0.93). The pooled results indicated that the odds of having an occupational injury were 4.06 times higher among workers who did not use personal protective equipment compared to those who used such equipment. Likewise the odds of occupational injuries was increased by 1.65 among night shift workers compared to the counterpart.
The global prevalence of occupational injuries in iron and steel industries was 55%. The results indicate that night work shift and the lack of use of personal protective equipment has a higher impact than other factors in the occurrence of occupational injuries in the iron and steel industries.
与其他制造业相比，钢铁行业是世界上最危险的工作场所之一。工人面临多种职业危害，使他们面临致命和非致命伤害的高风险。目前，全球钢铁行业职业伤害的流行率和相关危险因素的数据分散且不完整。本研究旨在通过汇总全球钢铁行业工人职业伤害流行率及其相关因素的研究数据来解决这一问题。
使用 PubMed、HINARI、EMBASE 和 Google Scholar 系统地搜索了以英语发表的报告钢铁行业工人职业伤害及其相关危险因素的研究。MetaXL 版本 5.3 软件用于荟萃分析，以估计钢铁行业工人职业伤害和相关危险因素的总流行率。该研究方案已在 PROSPERO 上注册，编号为 CRD42022344258。
在 447 篇文章中，有 15 项来自 9 个国家的研究符合纳入标准。职业伤害的总流行率估计为 0.55（95%CI：0.15，0.93）。汇总结果表明，与使用个人防护设备的工人相比，未使用个人防护设备的工人发生职业伤害的几率高 4.06 倍。同样，与对照组相比，夜班工人发生职业伤害的几率增加了 1.65 倍。
全球钢铁行业职业伤害的流行率为 55%。结果表明，夜班工作和缺乏使用个人防护设备比其他因素对钢铁行业职业伤害的发生有更大的影响。
