Abstract
Background: The construction workers are vulnerable to fatigue due to high physical workload. This study aimed to investigate the relationship between overwork and heart rate in construction workers and propose a scheme to prevent overwork in advance.
Methods: We measured the heart rates of construction workers at a construction site of a residential and commercial complex in Seoul from August to October 2021 and develop an index that monitors overwork in real-time. A total of 66 Korean workers participated in the study, wearing real-time heart rate monitoring equipment. The relative heart rate (RHR) was calculated using the minimum and maximum heart rates, and the maximum acceptable working time (MAWT) was estimated using RHR to calculate the workload. The overwork index (OI) was defined as the cumulative workload evaluated with the MAWT. An appropriate scenario line (PSL) was set as an index that can be compared to the OI to evaluate the degree of overwork in real-time. The excess overwork index (EOI) was evaluated in real-time during work performance using the difference between the OI and the PSL. The EOI value was used to perform receiver operating characteristic (ROC) curve analysis to find the optimal cut-off value for classification of overwork state.
Results: Of the 60 participants analyzed, 28 (46.7%) were classified as the overwork group based on their RHR. ROC curve analysis showed that the EOI was a good predictor of overwork, with an area under the curve of 0.824. The optimal cut-off values ranged from 21.8% to 24.0% depending on the method used to determine the cut-off point.
Conclusion: The EOI showed promising results as a predictive tool to assess overwork in real-time using heart rate monitoring and calculation through MAWT. Further research is needed to assess physical workload accurately and determine cut-off values across industries.
期刊介绍：
Annals of Occupational and Environmental Medicine (AOEM) is an open access journal that considers original contributions relevant to occupational and environmental medicine and related fields, in the form of original articles, review articles, short letters and case reports. AOEM is aimed at clinicians and researchers working in the wide-ranging discipline of occupational and environmental medicine. Topic areas focus on, but are not limited to, interactions between work and health, covering occupational and environmental epidemiology, toxicology, hygiene, diagnosis and treatment of diseases, management, organization and policy. As the official journal of the Korean Society of Occupational and Environmental Medicine (KSOEM), members and authors based in the Republic of Korea are entitled to a discounted article-processing charge when they publish in AOEM.
