No. Author (year) Purpose No. of participants Instrument of QOL Influencing factors Key findings
1 Kwak, Jee, Nam & Lee (2005) Health habits related to HRQoL and overall health 386 HRQoL (SF-36) Health habits, sleep time and breakfast, exercise, maintenance of normal weight Health habits, sleep time per day, breakfast, exercise, and maintenance of normal weight are the most important factors related to HRQoL.
2 Eom & Lee (2009) Predict the influencing factors by identifying the characteristics of the subject, job stress, self-esteem, depression, health-promoting lifestyle and quality of life 213 Quality of life (WHOQOL-100) Health promotion lifestyle, depression, self-esteem, working hours The predictors of the quality of life were high in the order of health-promoting lifestyle, depression, self-esteem, and working hours.
3 Lee & Jung (2011) To propose and to test a predictive model that could explain the workers' quality of life 901 Quality of life (SWLS) Behavioral factors, environmental factors, health level Behavior, environment, and health were found to have significant direct effect on quality of life. Indirect factors were perceived biological, predisposing, reinforcing, and enabling.
4 Ko, Lee & Ko (2013) To investigate the effect of general office workers' musculoskeletal symptoms on job stress, self-efficacy, depression, and HRQoL. 80 HRQoL (SF-36) Job stress, self-efficacy, depression There were significant differences in job stress, self-efficacy, depression and HRQoL according to the degree of subjective musculoskeletal symptoms. Depression, self-efficacy, job stress were significantly correlated; however, HRQoL can be affected by musculoskeletal pain for office workers.
5 Hwang & Park (2015) To investigate Korean blue-collar workers' HRQoL and influencing factors in Korean blue-collar workers. 109 HRQoL (SF-36) Depression, self-efficacy, education level The significant predictors for HRQoL were education level, depression and self-efficacy.
6 Park et al. (2015) To identify the effects of sleep quality and occupational stress on HRQoL among a university's security workers. 128 HRQoL (SF-12v2) Academic background, overtime work and interruption of breaks are job stress The interrupted rest time was significantly negatively related to occupational stress. The occupational stress significantly affected sleep quality. The significant variable affecting Physical Component Score (PCS) and Mental Component Score (MCS) was sleep quality and occupational stress, respectively.
7 Lee & Phee (2016) To investigate female labor workers' occupational stress and musculoskeletal symptom on their HRQoL. 112 HRQoL (SF-36) Job stress, degree of pain, duration of pain, frequency of pain, physical burden Factors significantly affecting HRQoL were found to be: occupational stress, degree of pain, with medium pain and extremely severe pain, duration of pain, with more than 1 week-less than 1 month and more than 6 months, frequancy of pain, with once per 2~3 months, responses to pain such as medical leave. use of workers' compensation insurance, and task change.
8 Park, Chae & Kim (2017) To investigate the effects of overtime work on the HRQoL of Korean blue-collar workers. 229 Euro-QOL-5 Dimension (EQ-5D) Overtime, depression, night work The significant predictors for HRQoL were overtime work, depression and night shift work.
9 Jeong, Jeong & Han To examine factors influencing HRQoL in women workers using the dataset of the Korean National Health and Nutritional Examination Survey. 955 Euro-QOL-5 Dimension (EQ-5D) Education level, arthritis diagnosis A positive relationship was found between education and HRQoL in women workers and non-osteoarthritis and HRQoL in women workers.
10 Jung, Yeo & Chai (2018) To investigate the effects of physical environment in the workplace on the HRQoL and sleeping hours of workers in low-income household, and examined the process of stress mediation effect. 531 Euro-QOL-5 Dimension (EQ-5D) Harmful work environment factors, stress at work The higher the perceived harmful work environment factors in the workplace, the higher the stress and the lower the HRQoL.
11 Sohn (2018) To examine factors influencing HRQoL of waged worker 10,806 Euro-QOL-5 Dimension (EQ-5D) Job stress, subjective health status, degree of pain, duration of pain, frequency of pain, physical burden The significant predictors of HRQoL were depression, subjective health status, age, activity limitation, education, worker status, monthly income, drinking, smoking, physical injury, stress, and moderate physical activity.
12 Kim & Kim (2019) To investigate variables affecting HRQoL of life of manufacturing industry workers. 200 HRQoL (SF-36) Job stress, sleep quality Occupational stress, depression, and religion were statistically significant variables of the mental component score with an explanatory power of 43.3%.
13 Lee & Noh (2020) To identify factors associated with the mental HRQoL of Korean workers. 192 HRQoL (SF-36) Resilience, anxiety, depression, subjective stress A common predicting factor associated with the four domains of HRQoL was identified as perceived stress symptoms.
14 Jung & Kim (2020) To identify the mediating effect of health promoting behavior in the relationship between depression and HRQoL, and between social support and HRQoL among migrant workers 152 World health organization quality of life (WHOQOL-BREF) Depression, social support, health promotion behavior Health promoting behavior showed partial mediating effects in the relationship between depression and HRQoL, and showed partial mediating effects in the relationship between the social support and HRQoL.
