Impact of COVID-19 on health status of self-employed workers.

OBJECTIVES

This study assessed the impact of the COVID-19 pandemic on the health status of self-employed workers by comparing their status before and during the pandemic, using nationwide data from the Korean Working Conditions Survey.

METHODS

The final study included 16 620 and 14 342 self-employed participants in the fifth (2017) and sixth (2020-2021) surveys, respectively. Musculoskeletal symptoms, systemic fatigue, headache, and eye strain, as well as mental health status, such as anxiety, depression, and insomnia, were assessed using a structured questionnaire. Gender, age, education level, and income were adjusted for the multivariable logistic regression analysis to assess pre- and peri-pandemic changes in the health status based on working conditions.

RESULTS

Compared with the pre-pandemic period, all aspects of the health status of self-employed individuals surveyed during the peri-pandemic period showed deterioration. Back pain increased 3.4 times (adjusted odds ratio [OR] 3.44; 95% CI: 3.15-3.75) compared with the pre-pandemic period, followed by anxiety, which increased 2.1 times (adjusted OR 2.13; 95% CI: 1.79-2.54). For single-person businesses, the overall health status showed statistically significant deterioration, highlighting the heightened vulnerability of these groups during this period.

CONCLUSIONS

This study confirmed that the physical and mental health status of self-employed individuals significantly deteriorated during the COVID-19 pandemic period compared with the pre-pandemic period. These findings suggest the need for government health protection policies for vulnerable groups, such as self-employed individuals, during future pandemics when social control measures are implemented.
