Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.87

OBJECTIVES
This study was performed to survey worker's demands for worksite medical care and agency's intention for offering worksite medical care in Group Health Service Agency.
METHODS
One study subjects were employers, workers and office personnels in 167 factories. They were asked for medical care utilization behavior and worksite medical care demand. 121 employers(72.5%), 145 office personnels(86.8%) and 816 workers(60.5%) answered the questionnaire. The other subjects were doctors, nurses and administrators in 66 Group Health Service Agencies nationwide. They were asked for intention of offering worksite medical care in Group Health Service Agency through the mail survey. 31 doctors(47.0%), 38 nurses(57.6%) and 34 administrators answered the questionnaire.
RESULTS
87 percentage of doctors and 94 percentage of nurses had experiences of being requested to prescribe and laboratory examination. All nurses, 94 percentage of administrators and 76 percentage of doctors thought that it was necessary to give medical treatment at worksite. Also in worksite 85 percentage of employers, 86 percentage of office personnels and 81 percentage of workers answered that they accepted the worksite medical care when it would be given.
CONCLUSIONS
Worksite medical care should be permitted because almost of all workers and employers requested worksite medical care, and doctors and nurses in Group Health Service Agency were willing to give worksite medical care and there was necessity to prevent occupational cerebrovascular disease.

The Effect of ALAD Polymorphism on the Relationship of Blood and Bone Lead with Hematologic Biomarkers in Lead Exposed Workers: Hwa Sung Kim, Sung Soo Lee, Yong Bae Kim, Young Hwangbo, Gap Soo Lee, Kyu Dong Ahn, Bong Ki Jang, Byung Kook Lee; Korean Journal of Occupational and Environmental Medicine 2001;13(1):75-86. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.75

Abstract PDF: OBJECTIVES
To evaluate the effect of ALAD polymorphism on the relationship of blood and bone lead with hematologic biomarkers in lead exposed workers, 450 lead exposed workers and 85 non-lead exposed workers were selected.
METHODS
Blood lead and tibia bone lead were selected as parameters of lead exposure and blood ZPP, urinary ALA (ALAU), hemoglobin (Hb) and hematocrit (Hct) were chosen as parameters of hematologic effect of lead exposure. Genotype of each subject was assayed and expressed as ALAD1 and ALAD2. Demographic information such as sex, age and personal habit of smoking and drinking were collected. Job duration of lead exposed workers was also obtained.
RESULTS
The overall prevalence of the variant allele, ALAD2 in lead exposed workers was 9.6 %(43 out of 450 lead workers) which was not differed from control workers (9.4 % : 8 out of 85). The means of tibial lead and blood ZPP in lead workers with ALAD2 were lower than those of lead workers with ALAD1, but the differences were not statistically significant. After adjusting for possible confounders (sex, job duration, BMI, drinking and smoking status) only blood lead and bone lead contributed negatively to the level of hemoglobin with statistical significance without any contribution of ALAD genotype. On the other hand, no significant effect of blood lead, bone lead and ALAD genotype were observed on the level of hematocrit after controlling possible confounder. ALAD genotype in the multiple regression analysis of blood lead and bone lead with log transformed urinary ALA (LogALAU) after adjusting for possible confounders showed significant main and interaction effect on LogALAU simultaneously, which resulted lower LogALAU in lead exposed workers of ALAD2 than ALAD1. It was also observed only main effect of ALAD gene type on blood ZPP after adjusting possible confounder resulting lower ZPP in lead workers of ALAD2 than ALAD1.
CONCLUSIONS
With above results, it was found that ALAD polymorphism did not affect on the level of hemoglobin and hematocrit, but ALAD polymorphism made significant effect on the association of blood and bone lead with urinary ALA and blood ZPP. The lower urinary ALA and blood ZPP in ALAD2 lead workers suggested that ALAD2 genotype may be supportive for the protective effect of lead.

The Association of Exposure to Organic Solvents with Liver Function: Chi Young Ann, Kyung Jong Lee, Jae Bum Park, Jae Yeon Jang, Moon Jong Kim; Korean Journal of Occupational and Environmental Medicine 2001;13(1):64-74. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.64

Abstract PDF

OBJECTIVES
This study was conducted to evaluate the association of cumulative exposure to organic solvent with liver function.
METHODS
We conducted a cross sectional study. 461 male workers who perform painting job at a shipyard and use organic solvents routinely and 125 workers of the same shipyard who never have been exposed to organic solvents were studied. All subjects who were confirmed not having HBsAg surveyed their age, BMI(body mass index), alcohol drinking and smoking history, and examined liver function test (SGOT, SGPT, gamma-GTP, Total protein, albumin, total bilirubin, direct bilirubin). The amount of cumulative exposure (CE) to mixed organic solvents were measured by biological monitoring method using their metabolites in urine.
RESULTS
The CE was observed as a significant variable with logistic regression analysis on abnormality of SGOT(>35IU/L), SGPT(>40IU/L) and gamma-GTP(>63IU/L), their odds ratio were 1.10 (95 %CI, 1.02-1.20), 1.10 (95 %CI, 1.01-1.19), and 1.10 (95 %CI, 1.01-1.19) each.
CONCLUSIONS
Therefore we suggest that the cumulative exposure to mixed organic solvents might be a significant variable on abnormal liver function indices (SGOT, SGPT,gamma-GTP) in male shipyard workers

Assessment of Job Related Cumulative Trauma Disorders of Dentists in Daegu Metropolitan City: Man Joong Jeon, Joon Sakong, Joong Jung Lee, Hee Kyung Lee, Jong Hak Chung; Korean Journal of Occupational and Environmental Medicine 2001;13(1):55-63. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.55

Abstract PDF

OBJECTIVE: To investigate the symptom prevalence and aspects of symptoms for cumulative trauma disorders in dentists and elucidate their associated factors.
METHODS
A questionnaire-based investigation on demographic factors, work-related characteristics, psychosocial factors and symptoms of 512 dentists practicing in Daegu metropolitan city was conducted. Subsets of psychosocial characteristics, including job demand(5 items), psychosomatic strain(5 items), job insecurity, and type A behavior were also assessed. For the evaluation of symptoms early developed questionnaire by Song(1997)was used to investigate the parameters related to pains in the neck, shoulder, arm and elbow, wrist, finger, back or discomforts, such as pricking and numbing.
RESULTS
The symptom prevalence of cumulative trauma disorders, calculated based on NIOSH criteria, was high at 63.3 %; the most frequent site of complaint was the shoulder, followed by neck, back, hand and wrist, knee, foot and ankle. The most common approach position was direction of 9 to 10 o'clock. Most subjects had 5-10 years of work experience and those with such years of experience also complained most frequently of symptoms in the neck and shoulder areas. As to rate of symptom complaint according to the type of dental procedure, the highest rate was associated to periodontic treatment. According to age, those between the age of 30-40 had the highest symptom prevalence rate at 70 %. According to sex, women had the higher symptom prevalence rate. Unmarried subjects also had higher symptom prevalence rate. The results of logistic analysis showed that the higher the psychosomatic strain and job demand, the higher the symptom prevalence rate of cumulative trauma disorders. Moreover, the higher the score of type A behavior, the higher the symptom prevalence rate, and even those who changed the location of their practice for the last three months also showed high symptom prevalence rate.
CONCLUSIONS
The results of multiple logistic regression analysis, which incorporated demographic, work-related and psychosocial characteristics as independent variables, showed that women were at a higher risk than men in developing cumulative trauma disorders; and that the higher the psychosomatic strain and more frequent type A behavior, the higher the risk of developing cumulative trauma disorders. The above results seem to suggest that not only continual, repeated fine and skillful musculoskeletal movements and lengthy hours in an uncomfortable position but also the psychological stress related to patient satisfaction, can lead to cumulative trauma disorders.

Effect of Occupational Lead on Male Sex Hormones: Hyeong Su Kim, Soung Hoon Chang, Won Jin Lee, Jae Wook Choi, Jong Tae Park, Nam Won Paik, Rok Ho Kim; Korean Journal of Occupational and Environmental Medicine 2001;13(1):44-54. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.44

Abstract PDF: OBJECTIVES
This study was performed to evaluate the relationship between biological markers of lead exposure and level of sex hormones in men occupationally exposed to lead.
METHODS
In this study, 33 male workers who employed at smelting and battery factories were compared with 33 male workers who were not exposed to lead. As biological markers of lead exposure, hemoglobin, ZPP, blood lead and urine lead were measured. As sex hormones, FSH, LH, testosterone, SHBG and FTI were determined.
RESULTS
Hemoglobin level was significantly lower in exposed than in nonexposed group. Level of ZPP, blood lead, and urine lead were significantly higher in exposed than in nonexposed group. There was a trend that level of FSH, testosterone, SHBG, and FTI was lower in exposed than in nonexposed group respectively, but there were no statistical significance. In exposed group, FSH level was correlated with age, ZPP, and blood lead; testosterone level was correlated with hemoglobin, blood lead, urine lead, and SHBG; and FTI level was correlated with age.
CONCLUSIONS
Level of some sex hormones were lower in exposed than in nonexposed group but there were no statistical significance between the exposed and the nonexposed group. But level of sex hormones were correlated with several biological markers of lead in exposed group. It suggests that occupational lead exposure might affect sex hormones.

Assessment of Job Related Factors as Determinants of Incidence of Herniated Lumbar Disc: Joong Jung Lee, Jong Hak Chung; Korean Journal of Occupational and Environmental Medicine 2001;13(1):31-43. Published online March 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.1.31

Abstract PDF: OBJECTIVES
A case-control study was conducted on 2,323 male soldiers(771 herniated nucleus pulposus patients and 1542 controls) to identify risk factors for cumulative trauma disorders especially lower back.
METHODS
The collecting data included individual physical, psychological, and work environmental factors. Korea Military Personality Inventory(KMPI) was used to examine the assess trait that have been associated with clinically with herniated nucleus pulposus. A measurement of the workplace support system was obtained by using of the modified work APGAR, a brief, seven-item workplace function questionnaire.
RESULTS
The herniated nucleus pulposus patients were more common among Artillerymen and Engineer than among infantrymen. In logistic regression analysis of military occupational specialties, Artillerymen, Engineer, radio operator, driver were higher risk of herniated nucleus pulposus than infantrymen. Multivariate analysis of KMPI scales found hypochondriasis scale, hysteria scale, hypomania scale, social introversion scale to have strong relationship to incidence of herniated nucleus pulposus. And 'can communicate with peers' and 'enjoy job task' item of modified work APGAR to have strong relationship to incidence of herniate nucleus pulposus CONCLUSIONS: Study of the relative contributions of many physical and non physical variable shows that evaluations of back problems in workplace that exclude these highly significant work perception and psychosocial variables are of limited value. Simple, unidimensional approaches that ignore the effect of work perceptions and psychological factors on back problems reporting oversimplify a multifaceted problem. These findings emphasize the importance of adopting a broader approach to the multifaceted problem of back complaint in workplace.

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.
