The construction industry in Pakistan employs 8% of the labour force, contributing 3% to the national GDP. This study aimed to determine the prevalence and associated factors of occupational injuries among construction workers in Karachi. We conducted a cross-sectional survey among 448 men from 10 construction sites in Karachi between June and October 2022. Workers aged ≥18 years involved in masonry, cleaning, machine operating, and supervision tasks were recruited and completed a structured, interviewer-administered questionnaire. Occupational injury was defined as "any injury at work over the last year for which the worker sought medical care or took time off work". We found the prevalence of occupational injury to be 26% (n = 116). Workers from small construction were more likely to report injuries, with an OR of 2.01 (95% CI: 1.30-3.12). Additionally, those working more than 8 hours daily had greater odds of injury, with an OR of 2.30 (95% CI: 1.45-3.67). This study found a high prevalence of injuries among construction workers in Karachi, Pakistan, emphasizing the need for preventive measures and interventions for improving health and safety at construction sites.
巴基斯坦的建筑业雇佣了8%的劳动力，对国家GDP的贡献率为3%。本研究旨在确定卡拉奇建筑工人职业伤害的患病率及相关因素。2022年6月至10月期间，我们对卡拉奇10个建筑工地的448名男性进行了横断面调查。招募了年龄≥18岁、从事砌砖、清洁、机器操作和监督任务的工人，并完成了一份由访谈员管理的结构化问卷。职业伤害被定义为“工人在过去一年中因工作受伤而寻求医疗护理或请假”。我们发现职业伤害的患病率为26%（n = 116）。小型建筑企业的工人更有可能报告受伤情况，比值比为2.01（95%置信区间：1.30 - 3.12）。此外，每天工作超过8小时的工人受伤几率更高，比值比为2.30（95%置信区间：1.45 - 3.67）。本研究发现，巴基斯坦卡拉奇的建筑工人受伤患病率很高，强调需要采取预防措施和干预措施，以改善建筑工地的健康与安全状况。
