The Effect of Breath Hold Diving on Bone Mineral Density of Women Fishery Diver: Hwan Sik Hwang, Hyun Rim Choi; Korean Journal of Occupational and Environmental Medicine 2003;15(4):411-421. Published online December 31, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.4.411

Abstract PDF: OBJECTIVES
The aim of this study was to determine the effect of breathhold diving on female diver's bone mineral density (BMD).
METHODS
A cross-sectional observational study was carried out utilizing a health checkup of divers and controls at a hospital in Jeju city, Korea. Female divers (n=61) were matched with non-diver controls (n=61) by age, weight and postmenopausal year. BMD of the proximal femur(femoral neck, trochanter and Ward's triangle) was assessed by dual-energy X-ray absorptiometry (DEXA).
RESULTS
The average diving duration of the female divers was 34+/-13 years. The BMD of the divers was higher than that of the controls in the femur neck and trochanter (p<0.05). On correlations analysis, the status of menopause, age, body weight and age at menarche were significantly correlated with proximal femur BMD in the divers (p<0.05). On multiple regression analysis, age and body weight were predictors of proximal femur BMD in the divers. On linear regression analysis of proximal femur BMD according to age in the divers and controls, regression coefficients of the divers were lower in all 3 areas of the proximal femur than the controls.
CONCLUSIONS
BMD of the divers was higher than that of the controls in the femur neck and trochanter. There was a tendency for BMD of the divers to decrease faster than that of the controls with increasing age.

Health Evaluation of ex-workers occupationally exposed to Carbon disulfide: Subjective Symptoms and Related Factors according to compensation for CS2 poisoning: Kyung Jae Lee, Joo Ja Kim, Hyun Rim Choi, Gil Seong Yang, Ho Kim, Shang Hyuk Yim, Yun Geun Lee; Korean Journal of Occupational and Environmental Medicine 2003;15(2):150-161. Published online June 30, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.2.150

OBJECTIVES
To investigate the chronological subjective symptoms and related factors in ex-workers who were occupationally exposed to Carbon disulfide.
METHODS
One hundred and seventy-seven subjects (147 males and 30 females) were randomly selected among ex-workers and interviewed by well trained doctors, who filled out a structured questionnaire developed by authors on the subjective symptoms. The questionnaire was composed of symptoms in the head and neck, and those of the neuro-psychological, respiratory, endocrine, musculoskeletal, and reproductive systems. Other factors such as general and occupational characteristics including work department, work duration, duration since cessation of exposure, and compensation for occupational disease were also investigated.
RESULTS
The mean subject age was 55.4 years. The mean cumulative exposure index (CEI) was 38.96 +/- 31.18. CEI was significantly higher in the compensated group (47.61 +/- 32.51) than in the non-compensated group (26.81 +/- 24.75)(p=0.000). Symptom complaints were significantly higher in the compensated group in all organ systems, and their incidence increased gradually until 10 years after cessation of work, and then decreased. The mean duration for cessation of exposure at the time of compensation was 10.97 years. The significantly different factors between the compensated group and the non-compensated group were total cumulative exposure index and the time interval between the cessation of work and the time of compensation.
CONCLUSION
Our findings suggest that total cumulative exposure index and the time interval between the cessation of work and the time of compensation may be important factors affecting the compensation for occupational disease. Therefore, further studies will be necessary.

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.

Knowledge and Attitude towards the Noise-Induced Hearing Loss of the Workers with Hearing Impairment in the Noisy Workplace: Hyun Rim Choi, Won Chul Lee; Korean Journal of Occupational and Environmental Medicine 1996;8(1):105-118. Published online February 29, 1996; DOI: https://doi.org/10.35371/kjoem.1996.8.1.105

Abstract PDF

This study was designed to survey the knowledge and attitude towards the noise-induced hearing loss (NIHL) of the workers with hearing impairment who are working at the noisy workplaces. The subjects were 423 workers selected from noisy workplaces, where the noise level was 85dB and over, and whose hearing impairment was 30 dB and over at 1,000 Hz or 40 dB and over at 4,000 Hz in the primary screening auditory test. For this study, a questionnaire was applied to the study subjects studying their knowledge and attitude towards the noise-induced hearing loss including their personal characteristics. Only 379 workers completed the questionnaires sincerely except 18 workers who did not show hearing impairment, and they were divided into three groups according to their status of hearing impairment: noise-induced hearing loss (Di), suspected hearing loss (0, hearing loss with medical reasons (D2), for their comparison of their knowledge and attitude towards the noise-indueed hearing loss. The workers who took auditory test at employment were 47.8% and who took auditory test last year after employment were 76.8%. The workers who put on protection device after the; test in 77.1%. The workers did not know the fact that they would work at the noisy workplace in 31.9%. The disturbance of daily communication is significantly different symtom among 3 groups (P<0.01). The workers answered that noise did not affect the body adversely in 4.7% and NIHL was not problem if it did not disturb daily life in 31.9%.In case they were diagnosed as NIHL, 68.6%-of the subjects answeredi-that they would put on protection devices thoroughly and 20.8% answered that they would ask for, medical care. And 39. 3% of them answered that they would want to stay at their present work-places even though they were ordered to change their workplaces to the another less noisy workplaces. The proportion of right answer in the article related NIHL was 61.2% in average. For the protection of NIHL, an effective hearing, conservation. program should be developed and provided to the labor working in the noisy workplace.
