Occupational injuries are a growing public health problem. Approximately 1,000 workers die daily from occupational injuries globally. Artisans working in the informal sector of the construction industry in many low/middle income countries like Nigeria have a higher injury predisposition. This study will assess the determinants of occupational injuries and design a safety intervention for informal sector artisans in the Nigerian construction industry.
A sequential mixed-methods design will be employed to study 840 bricklayers and carpenters (420 per artisan group) in Osun State, Nigeria. Quantitative data will be collected first while qualitative data will be collected thereafter. Thirdly, a modified Delphi-technique will be employed to co-design a safety education intervention. For the quantitative study, artisans will be recruited via multi-stage sampling and a semi-structured questionnaire will be administered to obtain information on artisans' socio-demographics, work-patterns and occupational injuries. A multivariable regression model will be used to determine the association between injury occurrence and independent variables. Twelve to sixteen focus group discussion (FGD) sessions will be conducted for artisans to obtain group perspectives about injuries and preferred safety training topics. From the FGD and quantitative study findings, a list of items for the safety training module will be compiled for the modified-Delphi process. Thereafter, the content validation index (CVI) will be derived and items with CVI of ≥0.80 will be included in the final safety training module.
This paper describes the process required to assess the determinants of occupational injuries among artisans in the informal sector of the construction industry in Nigeria and further proposes the design of a context-relevant safety training intervention. The information from this study will be essential in promoting safe working environments for construction artisans.
职业伤害是一个日益严重的公共卫生问题。全球每天约有 1000 名工人因职业伤害死亡。在尼日利亚等许多中低收入国家，从事建筑行业非正规部门工作的工匠受伤的可能性更高。本研究将评估职业伤害的决定因素，并为尼日利亚建筑行业非正规部门工匠设计一项安全干预措施。
本研究将采用序贯混合方法，在尼日利亚奥孙州研究 840 名砌砖工和木匠（每个工匠组 420 人）。首先收集定量数据，然后收集定性数据。最后，将采用修正德尔菲技术共同设计安全教育干预措施。在定量研究中，将通过多阶段抽样招募工匠，并通过半结构式问卷收集有关工匠社会人口统计学、工作模式和职业伤害的信息。将使用多变量回归模型确定伤害发生与自变量之间的关联。将为工匠进行 12-16 次焦点小组讨论（FGD），以获取有关伤害和首选安全培训主题的小组观点。根据 FGD 和定量研究结果，将为修改后的德尔菲过程编制安全培训模块的项目清单。此后，将得出内容有效性指数（CVI），并将 CVI≥0.80 的项目纳入最终安全培训模块。
本文描述了评估尼日利亚建筑行业非正规部门工匠职业伤害决定因素的过程，并进一步提出了设计与上下文相关的安全培训干预措施的方法。本研究提供的信息对于促进建筑工匠的安全工作环境至关重要。
