Distribution of working position among workers with varicose veins based on the National Health Insurance and National Employment Insurance data: Saemi Jung, Youngki Kim, Dongmug Kang, Se Yeong Kim, Inah Kim, Eun Mi Kim; Ann Occup Environ Med 2020;32:e21. Published online July 1, 2020; DOI: https://doi.org/10.35371/aoem.2020.32.e21

Background

This study aimed to determine the effect of specific working postures on the development of varicose veins (VV). By using Korea's National Health Insurance (NHI) and National Employment Insurance (NEI) data, we analyzed the general characteristic and difference in proportions of VV cases according to occupational working posture.

Methods

From the NEI and NHI data, participant demographics, such as gender, age, body mass index, and number of workers in specific occupations or industries were obtained. We classified the 240 occupations into blue-collar (BC) and white-collar (WC) occupations and subdivided them into standing, sitting, and walking groups according to the dominant working posture.

Results

The number of VV patients per 100,000 individuals increased with age, with a higher number of women than men and a higher number of patients in the BC than WC groups. For the BC group, the proportion of VV cases was the highest in the standing group, followed by the walking and sitting groups, but there was no significant difference between standing and walking groups in man. For the WC group, the standing group had a higher proportion of VV cases than the sitting group, but there was no significant difference between the standing and sitting group in man. In the BC group, the proportion of VV cases was the highest among medical and welfare-related elementary workers, bakers and cookie makers, automobile assemblers, cleaning and guarding-related elemental workers, and nurses and dental hygienists. In the WC group, the proportion of VV cases was the highest among food/lodging/tourism/entertainment/sports-related managers, environment/cleaning/protective services-related managers, finance and insurance clerks, accounting book-keeping clerks, and social welfare and counseling professionals.

Conclusions

This study was performed to determine the characteristics of VV with different working posture among Korean workers. It is expected to be the basis of further studies on occupational musculoskeletal diseases.

Selection of a High Risk Group and the Effectiveness of an Exercise Program on Musculoskeletal Symptoms in Small and Medium Sized Enterprises: Bo Kyoung Kim, Chung Yill Park, Hyeon Woo Yim, Jung Wan Koo, Kang Sook Lee; Korean Journal of Occupational and Environmental Medicine 2005;17(1):10-25.

Abstract PDF

OBJECTIVES
This study was conducted to provide data for the establishment of a practical and the effective exercise program for managing the musculoskeletal symptoms of workers who are employed in small and medium sized enterprises.
METHODS
The risk factors related to musculoskeletal disease management were chosen according to the relevant literatures, and were based on advise from experts on the Delphi method. Questionnaires on selected risk factors (with a 5-point Likert scale) were given to 785 subjects who worked in small and medium sized enterprises. The subjects were then classified in the risk group when they had the symptoms and recorded at least 3 points. From those subjects in the risk group, those who had both work-related factors and general characteristics factors (with an average of at least 3 points) were further classified as the high risk group. We performed a 12-week musculoskeletal exercise program for the low and high risk groups to analyze their changes in symptoms and complaints in order to estimate the effectiveness of the exercise program.
RESULTS
Out of 785 subjects, 454(57.8%) were in the risk group of musculoskeletal diseases and 121(15.4%) were in the high risk group. According to multiple logistic regression analysis of the factors for the musculoskeletal symptoms in the low risk group, the significant risk factors were sex and personal disease related with musculoskeletal disease, while the risk factors in the high risk group were age, sex, and personal disease related with musculoskeletal disease. After the 12-week exercise program was performed by the low risk group, the number of musculoskeletal symptom complaints in the control group did not significantly changed, whereas for the intervention group, the number of musculoskeletal symptom complaints significantly declined for all parts of the body. After the 12-week exercise program performed by the high risk group, the number of musculoskeletal symptom complaints in the control group was significantly enhanced for the arm and elbow parts. In the intervention group, the complaint rate for musculoskeletal symptoms significantly declined only for the low back.
CONCLUSION
The musculoskeletal symptoms were significantly improved by the exercise program in the low risk group, but not in the high risk group. It is suggested that control measures on administrative and/or work related factors, in addition to the exercise program should be considered simultaneously for the control of musculoskeletal symptoms in groups at high risk of musculoskeletal disease.
