Relationship between Job Stress and Pulse Wave Velocity as a Cardiovascular Risk Factor: Jung Ok Kong, Sang Baek Koh, Sei Jin Chang, Bong Suk Cha, Ho Keun Chung, Hong Ryul Choi, Kyung Hee Jung-Choi, Soon Ja Jeon; Korean Journal of Occupational and Environmental Medicine 2004;16(4):450-458. Published online December 31, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.4.450

OBJECTIVE: The objective of this study was to elucidate the relationship between job stress and pulse wave velocity (PWV) as a cardiovascular risk factor.
METHOD
The study design was cross-sectional, and a total of 234 industrial workers were recruited. A structured-questionnaire was used to assess the general characteristics and job characteristics (work demand, decision latitude) using a modified Karasek model. Cuffs were applied to the extremities and a microphone for phonocardiography was placed at the second intercostal space at the margin of the sternum. The subjects rested in a supine position for 5 min, and PWV was measured using a VP-1000(Colin Waveform analyzer).
RESULTS
There were significant correlations between blood pressure, glucose, total cholesterol, coagulation factor and PWV. The group with low decision latitude and high decision latitude showed higher levels of PWV, but the differences were not significan. The PWV (left) was significantly higher in the high strain group than in the lower strain group. After adjustment for age and cardiovascular risk factors, job strain was still associated with PWV.
CONCLUSION
These result suggest that the high strain group among workers is related to an increased risk of PWV as a marker of atherosclerosis.

Abstract PDF

OBJECTIVE: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases METHODS: 11 hospitals participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted.
RESULTS
Between Apri1 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. Most of the HAVS cases came from shipbuilding, and 172 of them (92.7 %) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9 %). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6 %) and 4 (12.1 %) cases of occupational asthma, the agents included isocyanate and welding fume, respectively. 64.7 % of the cases of occupational skin diseases were contact dermatitis, and organic solvents and welding fume were the main agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10 (58.8 %) of the cases were diagnosed as squamous cell carcinoma and 5 (29.4 %) as adenoma.
CONCLUSION
This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

Job Stress, Heart Rate Variability and Metabolic Syndrome: Sei Jin Chang, Sang Baek Koh, Hong Ryul Choi, Jong Min Woo, Bong Suk Cha, Jong Ku Park, Yong Hee Chen, Ho Keun Chung; Korean Journal of Occupational and Environmental Medicine 2004;16(1):70-81. Published online March 31, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.1.70

Abstract PDF

OBJECTIVE: A growing body of literature has documented that job stress is associated with the development of cardiovascular disease. Nevertheless, the pathophysiological mechanism of this association remains unclear. Therefore, we tried to elucidate the relationship between job stress, heart rate variability and metabolic syndrome.
METHOD
The study design was cross-sectional, and 169 industrial workers were recruited. A structured-questionnaire was used to assess the general characteristics and job characteristics (work demand, decision latitude). Heart rate variability (HRV) was recorded using SA-2000 (medi-core). HRV was assessed by time-domain and by frequency-domain analyses. Time domain analysis was performed for SDNN (Standard Deviation of NN interval), and spectral analysis for low-frequency (LF), high-frequency (HF) and total frequency power. Metabolic syndrome was defined on the basis of clustering of risk factors, when three or more of the following cardiovascular risk factors were included in the fifth quintile: glucose, systolic blood pressure, HDL-cholesterol (bottom quintile), triglyceride and waist-hip ratio.
RESULTS
The results showed that job characteristics were not associated with cardiovascular risk factors. The high strain group had a less favorable cardiovascular risk profile with higher levels of blood pressure, glucose, homocysteine, and clotting factor than the lower strain group (low strain+passive+active group), but the difference was not statistically significant. The SDNN of HRV was significantly lower in the high strain group than in the low strain group. The prevalence of metabolic syndrome in the low strain, passive, active and high strain groups was 9.7%, 13.9%, 14.9% and 23.8%, respectively. In the high strain group, the metabolic syndrome was significantly related to a decreased SDNN. However, we could not find a significant association in LF/HF ratio.
CONCLUSION
This result suggests that decreased HRV does not play a role in the development of disease; however, it can induce cardiovascular abnormalities or dysfunctions related to the onset of heart disease among high risk groups.

Job instability of Labor Market and Preplacement Health Examination: the Case of Hearing Loss: Sang Baek Koh, Kyoo Sang Kim, Sei Jin Chang, Bong Suk Cha, Jong Ku Park, Dong Mug Kang, Jai Young Kim, Soo Keun Kim, Hong Ryul Choi; Korean Journal of Occupational and Environmental Medicine 2002;14(1):57-68. Published online March 31, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.1.57

Abstract PDF: OBJECTIVES
This study examines the problem of the preplacement health examination in terms of hearing loss case, where workers have been experiencing job instability in the labor market.
METHODS
In order to measure the 2-year job retention rate of employees in 79 shipbuilding subcontracted companies in Kyongnam province, we utilized the same methods as those used by Neumark et al(1999), and Bernhardt et al(1999). We surveyed 79 heath and safety personnel from the companies with a questionnaire to evaluate the present status of the preplacement health examination. We reviewed the preplacement health certificates(result of audiometric hearing thresholds) of 1,818 recruits issued by Daewoo hospital from January 1 to June 30, 2001.
RESULTS
The job retention rate was 40.3 %(male 38.53 %, female 52.01 %). Of the 79 health and safety personnel of companies, 44(55.7 %) perceived the preplacement health examination as a tool for the selection of recruits, 3(3.8 %) as a procedure for job fitting and 31(39.2 %) as both. Most of them were against the acceptance of recruits with hearing loss, spinal disease and hepatitis. Among the 1,818 workers who underwent the preplacement health examination, 530(29.1 %) were examined after employment, but 1,096(60.3 %) were examined before employment. The number with previous job experience was 1,591(87.5 %). In the audiometric hearing threshold results, the prevalence of hearing loss was positively correlated with age. There was a significant difference in the prevalence of hearing loss depending on previous job and number of quitting at 4,000 Hz.
CONCLUSIONS
The comparison of 2-year job retention rates before and after the Korean economic crisis of 1997 suggests that job stability has been aggravated especially for cohorts of long tenure, irregular job, and old age. This evidence shows that previous job and age play a role in determining worker employment based on perceived results from the preplacement health examination. This result suggests that a pre-employment health examination be substituted for the preplacement health examination based on the essential job functions and reasonable accommodation. Because it has little relevance in a wide range of employment and minor health problems, the results of this examination should not debar applicants from employment.

The Similar Exposure Group and Exposure Variation in Ship-Building Painters: Focused on Xylene Exposure: Sang Baek Koh, Young Man Roh, Hyeon Woo Yim, Yong Chul Shin, Soo Keun Kim, Hong Ryul Choi, Jai Young Kim, Soung Hoon Chang; Korean Journal of Occupational and Environmental Medicine 2001;13(4):413-422. Published online December 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.4.413

Abstract PDF

OBJECTIVES
This study was conducted to assess the concentration of xylene exposure and exposure variability of a similar exposure group(SEG) in accordance with job title and confined space.
METHOD
The study subjects included 28 workers working in the painting process in the ship-building industry. Measurement of subjects were repeated three times. Within and between-worker exposure variance components were estimated from log-transformed exposure concentrations employing a one-way nested random effects analysis of variance model. A uniformly exposed group was defined as one where the between-worker variance(sigmaB2) was less than or equal to 0.031 or bwR95 RESULT
The results indicated that, contrary to popular belief, similar exposed groups based on job title were heterogeneous. The between-worker variance(sigmaB 2) is large(>or=0.031) and the ratios of the 97.5th and 2.5th percentile workers of the log normally distributed exposures of each group of workers was more than 2. However dividing job title into confined space(in-block, out-block, in/out-block) decreased the between-worker exposure variability.
CONCLUSION
This study focused on the quantitative aspects of exposure in painters in the ship-building industry. We cannot accept the assumption that SEG are uniformly exposed, as a major component of variation in exposure relates to differences in tasks or other factors. Therefore, the observational schemes can be improved by investigating jobspecific task and practice.

The Association of Workplace Cumulative Noise Exposure and Blood Pressure: Sang Yun Lee, Jai Young Kim, Hyoung June Im, Ki Jung Yoon, Hong Ryul Choi, Sang Baek Koh, Dae Hee Kang, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 2001;13(2):200-208. Published online June 30, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.2.200

Abstract PDF

OBJECTIVES
The association of workplace cumulative noise exposure and blood pressure was investigated in this study using cross-sectional design.
METHODS
The study population comprised 852 manufacturing male workers of whom occupational health examination data, questionnaire and personnel records were available. Workplace ambient noise monitoring data was used for calculating individual cumulative noise exposure level. Mean of each systolic and diastolic blood pressure of occupational health examination data was used for individual systolic and diastolic blood pressure level. Possible confounding variables including family history of hypertension, smoking habit, alcohol drinking habit were collected by questionnaire. On the basis of job location and duration of work at the location, a cumulative time-weighted average noise level was calculated for each workers. According to this cumulative noise exposure level, each study subject was categorized as low noise exposure group, moderate noise exposure group, high noise exposure group, very high noise exposure group. Among noise exposure groups, mean of systolic and diastolic blood pressure was compared after adjusting possible confounding variables such as age, body mass index, serum cholesterol level, family history of hypertension, smoking history, alcohol drinking habit.
RESULTS
After adjusting possible confounding variables, noise exposure group was significant explanatory variables for both systolic and diastolic blood pressure, and mean of both systolic and diastolic blood pressure of very high exposure group was higher than that of low exposure group.
CONCLUSIONS
These findings suggested that the high cumulative noise exposure might elevate the blood pressure.

The Health Status Assessment of Subcontracted Workers: Hong Ryul Choi, Sang Baek Koh, Sei Jin Chang, Bong Suk Cha, Hyoung June Im, Sang Yun Lee, Jai Young Kim, Dong Mug Kang, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 2001;13(1):18-30. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.18

Abstract PDF

OBJECTIVES
The strategy for the labor flexibility through subcontracted labor have brought a negative effect on the lives of the workers, such as the increase of the unstable employment. This study was conducted to analyze the relationship between the employment of subcontracted firms and the health status of them, and to find out some problems which have been caused in the process of health evaluation and the characteristics of social exclusion.
METHODS
We reviewed the periodical health examination and preemployment health examination in order to compare health status of the subcontracted workers with those of the parent firm workers. The SF-36 questionnaire was administered to assess the self-perceived health status.
RESULTS
The result shows that compared to the working duration of the parent firm workers, those of the subcontracted workers were shorter, and the job transfer rate was higher. In the periodical health examination, the prevalence of occupational and general disease was higher in the parent firm(10%) than in the subcontracted firms(6%). Preemployment health examination plays an important role in worker's health management. Among 6,260 workers who received preemployment health examination, the prevalence of disease was 37.9%. Mean scores of health status measured by SF-36 were lower in the subcontracted firm than in the parent firm.
CONCLUSIONS
Due to social exclusion of the subcontracted workers from the periodical health examination, there is a possibility that the periodical health examination have the healthy worker effect. These results suggests that the preemployment health examination could be a more appropriate indicator which is able to assess the health status of the subcontracted workers than the periodical health examination.

Incidence and Risk Factors for Occupational Low Back Pain Among Shipyard Workers: Sang Baek Koh, Hyong Sik Kim, Hong Ryul Choi, Ji Hee Kim, In Hyok Song, Jun Han Park, Jong Ku Park, Sei Jin Chang, Bong Seok Cha; Korean Journal of Occupational and Environmental Medicine 2000;12(1):1-11. Published online March 31, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.1.1

Abstract PDF

OBJECTIVES
This study was conducted to estimate the incidence rate, and to identify the risk factors for the occupational low back pain among shipyard workers.
METHODS
The study subjects consisted of 9,784 workers who were employed in a ship-building industry(excluded workers who had a history of low pack pain before 1995 or did not take periodic health examination in 1995). The cases were 220 people who experienced back pain from January 1, 1996 to December 31, 1998. To assess risk factors for occupational low back pain, Cox propotional hazard model was used.
RESULTS
During the recent three years from 1996 to 1998, the incidence rate per 1,000 persons was 7. 8 in 1996, 8. 8 in 1997, and 3. 1 in 1998. The main causes of work-related low back pain were sprain, strain and disc herniation. Lifting was the most common cause of back pain(35. 3%), and carrying(10.2%) and pulling(8.0%) were followed. In Cox proportional harzard model, independent risk factors for back pain were body mass index(R.R.; 1.54, 959o C.I.: 1.06-2.25), shift work(R.R.; 1.65, 95% C.I.: 1.19-2.28), and lifting heavy material(R.R. ; 3.95, 95% C.I: 2.29-6.82).
CONCLUSIONS
This study suggests that the risk factors of back pain in shipyard workers were body mass index, shift work and lifting.

Evaluation of Health Exams on Local Vibration Illness among Shipyard Workers: Yeong Su Ju, Hong Ryul Choi, Mi Kyung Kim, Hong Sohn, Sun Ja Jeon, Sung Il Cho, Hyong Sik Kim; Korean Journal of Occupational and Environmental Medicine 1998;10(4):413-427. Published online December 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.4.413

Abstract PDF

A hand-arm vibration syndrome, local vibration illness, occurs in some workers who use hand held vibration tools. It consists of white fingers, diffusely distributed finger neuropathy, pain in the hand and arm, and a small excess risk of osteoarthritis. This study is aimed to identify effective methods to confirm local vibration illness among various health exams, which are mentioned in worker's special health exam regulation. In addition, this study is aimed to quantitatively assess the daily vibration exposure level as a major determinant of vibration illness. The subjects, 46 vibration workers, were selected according to the results of the first special health exam about vibration hazards at shipbuilding industry in 1997. They all had experiences of work related blanching of fingers. Fifteen controls, who had no vibration exposure at all, were also recruited to compare their test results with the results of vibration workers. We adopted 1 subjective and 6 objective tests to evaluate the effectiveness and feasibility for confirming local vibration illness. These tests were history taking of subjective symptoms according to the Stockholm classification, checking blood pressure of finger, checking grasp power, checking finger skin temperature, nail-bed pressing test, vibration perceptional threshold test, and skin prick test for pain perception. Among these, checking skin temperature, nail-bed pressing test, and vibration perception test included cold water provocations. We also estimated some vibration exposure levels of hand held vibration tools by using previously published data from one automobile company. In conclusion, history taking of subjective symptoms according to the Stockholm classification, nail-bed pressing test, and vibration perceptional threshold test were discovered to be effective to diagnose local vibration illness. Furthermore, vibration perceptional threshold on right fingers showed a dose-response relationship to daily vibration exposure levels. The parameter beta was 0.0005(+/-0.0002), and statistically significant by REM (random effects model).

Study on Perceived Occupational Psychosocial Stress and Work-related Musculoskeletal Disorders among VDT Works: Yeong Su Ju, Ho Jang Kwon, Dong Gyu Kim, Jai Yong Kim, Nam Jong Baek, Hong Ryul Choi, In Keun Bae, Jong Man Park, Jong Du Kang, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 1998;10(4):463-475. Published online December 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.4.463

Abstract PDF

It has been hypothesized that jobs that have both high psychological demands and low decision latitude ('job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome (MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model (16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects (n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-strain group, and OR of musculoskeletal disorder was 2.446 (95% C.I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.
