Introduction: Although shift work is an inevitable form of labor in modern society, it has been identified as a cause of many ailments, such as cancer and musculoskeletal disorders. Meanwhile, previous studies have also shown that musculoskeletal disorders account for a large proportion of total industrial accidents and a high prevalence rate of these ailments has been found in shift workers.
Methods: Among the respondents to the 5th Korea Working Conditions Survey (KWCS) 3,916 shift workers (2,658 of whom have not experienced musculoskeletal pain and 1,258 who have experienced musculoskeletal pain) were asked how the work regularity of shift workers affected musculoskeletal pain.
Results: The results of a dichotomous logistic regression by correcting the demographic characteristics of the study subjects showed a lower prevalence of musculoskeletal pain in the ‘High’ regularity group compared to the ‘Intermediate’ regularity group for the criterion ‘Regularity of Time Fixation’. A lower prevalence of musculoskeletal pain was shown in the ‘High’ and ‘Moderate’ regularity group compared to the ‘Very Low’ regularity one.
Conclusions: Based on these findings, it was found that musculoskeletal pain occurs less when the work regularity of shift workers is ‘Very high’ or ‘Intermediate’, and the effect of working regularity on musculoskeletal pain varies for each shift type of work. It is deemed that more precise observation and understanding are required when managing the working environment of shift workers, and further study of regarding this issue is needed.
