abstract
The aim is to investigate and describe the health conditions of workers who are employed in precarious work settings in Mexico. Specifically, the study aims to provide insight on the health status of workers who are vulnerable due to the informal nature of their employment. Through the evaluation of three different scenarios of precarious employment (n = 110), including workers in mercury miner (workers A), brick-kilns (workers B), and quarries workers (workers C). The study analyzes clinical parameters to determine the workers\%27 renal health condition and assesses their pulmonary function using spirometry. Multivariate analyses and Spearman correlation are performed to determine the contribution of length of service to workers\%27 health parameters. Workers B have the highest incidence of clinical health alterations, with the highest BMI and prediabetes/diabetes index, albumin creatinine ratio, and eGFR. Moreover, pulmonary function parameters show a decrease in %25FEV1/FVC in workers B and C compared to workers A, while workers A demonstrate a more significant decrease in %25FEV1. Additionally, a negative correlation is observed between the length of service in precarious work settings and lung parameters (r = -0.538, p < 0.001). In conclusion, this study highlights the need to address the issue of precarious employment in Mexico by improving working conditions, access to healthcare and promoting social protection for workers, which can reduce the number of work-related illnesses and deaths and ensure the safety and health of workers.
