Strength and Limitation
The key strength of this study lies in the fact that it is the first empirical study assessing quality of life among quarry workers across Nigeria using a valid and reliable tool. The use of standard tool is the major strength of this study in that it avoided trial and error chance and its findings are reliable [45]. It is also the first empirical study that modelled the socio-demographic factors, workplace factors and WRMSDs with quality of life among the quarry workers in Nigeria.
The key limitation of this study lies in the cross-sectional design employed which may not have allowed for detailed exploration of the quality of life among the quarry workers. This study also focused on the quarry workers in Ebonyi state, Nigeria and therefore, the result may not be generalized to other quarry workers in other states in Nigeria.
