Abstract: The number of precarious workers is increasing globally, and precarious employment is becoming a public concern in terms of workers’ health. However, sufficient research on precarious employment and its impact on musculoskeletal pain (MSP) is lacking. This study aimed to investigate the relationship between precarious employment and the risk of MSP among Korean wage workers. After merging the data from the 4th and 5th Korean Working Conditions Surveys, 59,644 wage workers were analyzed. The control group comprised full-time permanent workers, and precarious employment was defined as workers involved in temporary or daily employment, or part-time workers. The outcome variable was the summed number of MSP in three anatomical sites (back, neck and upper limb, lower limb). Zero-inflated negative binomial analyses were selected to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) between precarious employment and MSP. In adjusted models with age, sex, educational level, income level, weekly working hours, and occupation, precarious employment was significantly associated with an increased risk of both MSP (OR 1.66 95% CI 1.56–1.77) and work-related MSP (OR 1.18 95% CI 1.11–1.25). Given the job insecurity and health inequity associated with precarious employment, special attention on precarious workers’ health is needed.
