The Effect of Shift Work on the Level of Self-Rated Health: Daehee Noh, Jong Ho Wang, Hyunrim Choi, Sinye Lim, Keunwhoe Kim, Chang Won Won, Kyunghee Jung-Choi; Korean Journal of Occupational and Environmental Medicine 2010;22(3):200-209. Published online September 30, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.3.200

OBJECTIVES
The present study was designed to determine the characteristics of shift work and the relationship between shift work and the level of self-rated health using the Korean Labor and Income Panel Study (KLIPS) data, which represents urban households in Korea.
METHODS
Using the 9th wave of KLIPS, this study analyzed 2,087 male workers aged 25 to 64 years; participants missing data were excluded from analysis. To determine the impact of shift work on the level of self-rated health, logistic regression analysis was applied that controlled for socio-demographic characteristics, labor environment, and health-related behaviors.
RESULTS
Shift workers comprised 13.4% of study subjects overall. The majority(69.2%) of participants were in 2-teams and in 2-shifts. Week 1 shift cycle changes were the highest, 56.3%. The risk of poor self-rated health was not significantly higher among shift workers compared to non-shift workers (OR=1.08, 95% CI=0.79~1.48). When divided by tenure, shift workers with more than 10-years experience (OR=1.79, 95% CI=0.91~3.50) tended to show greater risk than non-shift workers at marginal significance.
CONCLUSIONS
In the present study, a significantly higher risk of self-rated poor health among shift workers was not observed. However, shift workers with more than 10-years experience tended to show increased health risk compared to non-shift workers. Further studies are required to determine time-series data and to consider both healthy worker effect and information bias.

RELATED FACTORS OF DIAGNOSIS OF CHRONIC CARBON DISULFIDE POISONING: Byung Sung Kim, Hyun Rim Choi, Chang Won Won; Korean Journal of Occupational and Environmental Medicine 1997;9(1):1-11. Published online February 28, 1997; DOI: https://doi.org/10.35371/kjoem.1997.9.1.1

Abstract PDF

The purpose of this study was to compare the characteristics between chronic CS2 poisoning group and non-poisoning group, to find out major factors for decision of chronic CS2 poisoning, to describe the characteristics of cerebral infarctions, and to find out the related factors of cerebral infarctions. The study subjects were 220 ex-employees from W company and the study period was from August, 1993 to November, 1995. The proportion rate of chronic CS2 poisoning was higher in older age groups and longer work duration groups. The rate differed by cerebral infarction, microaneurysm, other retina lesions, polyneuropathy, psychiatric lesions, and sensorineural hearing loss. The cerebral infarction was found to be mainly multiple and the frequently occurred locations were periventricular white matter, frontal lobe and basal ganglia. The logistic regression for chronic CS2 poisoning showed that the major factors were microaneurysm, cerebral infarction, polyneuropathy, other retina lesions, diastolic blood pressure, and sensorineural hearing loss. Among the approved group 117 patients were followed up continuously at the outpatient clinic, 62.4% of the patients had hypertension, 61.5% had polyneuropathy, 52.1% had cerebral infarction, 35.0% had hyperlipidemia, 29.9% had liver disease, 15.4% had psychiatric diseases, 6.0% had angina, and 4.3% had anemia. For the hypertensive patients, 1.9 kinds of antihypertensive drugs were needed to control the blood pressure, and the BP decreased from 164/101 mmHg to 131/81 mmHg.
