Physical and mental health problems of self-employed small business owners in South Korea

Self-employed business owners in Korea make up one-quarter of the working population, and half of those who are self-employed are in micro and small businesses. Compared to the significant research interest in business management and economics, to date, there has been little interest in the health of small business owners. We investigated the health status of self-employed small business owners compared to standard workers.

The third Korean Working Conditions Survey, which included a total of 32 630 adults aged 20 to 59 years, was analyzed. A small business was defined as an enterprise with between 0 and 4 workers. Standard employment included full-time employment with a permanent or 1-year contract. Health outcomes included eight types of physical health and mental health problems assessed using the WHO-5 Wellbeing Index.

Small business groups were found to have an increased prevalence of depression after controlling for all potential covariates (odds ratio [OR] = 1.37; 95% confidence interval [CI] 1.29-1.47). In addition, the prevalence of work-related physical health problems was significantly higher among self-employed small business owners in a full adjusted model: backache (OR = 1.16; 95% CI, 1.06-1.26), muscular pains in upper limbs (OR = 1.19; 95% CI, 1.12-1.27), and muscular pains in lower limbs (OR = 1.14; 95% CI, 1.07-1.22).

We found a positive association between small business entrepreneurs and increased prevalence of mental and physical illness in adults in the Republic of Korea.
