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.
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.
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.
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.
本研究旨在确定特定工作姿势对静脉曲张（VV）发病的影响。通过使用韩国国民健康保险（NHI）和国民就业保险（NEI）数据，我们分析了根据职业工作姿势划分的VV病例的一般特征和比例差异。
从NEI和NHI数据中获取参与者的人口统计学信息，如性别、年龄、体重指数以及特定职业或行业的工人数量。我们将240种职业分为蓝领（BC）和白领（WC）职业，并根据主要工作姿势细分为站立、坐着和行走组。
每10万人中VV患者的数量随年龄增加，女性患者数量多于男性，BC组患者数量多于WC组。对于BC组，站立组VV病例的比例最高，其次是行走组和坐着组，但男性站立组和行走组之间无显著差异。对于WC组而言，站立组VV病例的比例高于坐着组，但男性站立组和坐着组之间无显著差异。在BC组中，医疗和福利相关初级工人、面包师和饼干制作工、汽车装配工、清洁和保安相关初级工人以及护士和牙科保健员中VV病例的比例最高。在WC组中，食品/住宿/旅游/娱乐/体育相关经理、环境/清洁/保护服务相关经理、金融和保险职员、会计簿记员以及社会福利和咨询专业人员中VV病例的比例最高。
本研究旨在确定韩国工人中不同工作姿势下VV的特征。预计这将成为进一步研究职业性肌肉骨骼疾病的基础。
