The relationships between occupational characteristics and symptoms of varicose veins and nocturnal leg cramps and their gender differences were explored in a Korean population. The study population was 2165 workers from various occupations (55.6% female). Multiple logistic regression analyses were conducted to reveal factors related to symptoms of varicose veins and nocturnal leg cramps. The prevalence of varicose veins and nocturnal leg cramps was higher among women than men. The characteristics of standing work were different according to gender. In gender stratified analysis, the odds ratio of varicose veins was significantly high for prolonged standing for male and female workers. However, the odds ratio of nocturnal leg cramps was only significant among prolonged standing male workers. The models including gender, prolonged standing and occupations in this order presented that gender is not significantly associated with varicose veins after occupations were added to the model. Prolonged standing at work may be a more important risk factor for varicose veins and nocturnal leg cramps than biological differences between women and men. Therefore, effective interventions to interrupt or reduce prolonged standing at work should be implemented for the prevention of varicose veins and nocturnal leg cramps.
This paper shows associations between occupational characteristics and symptoms of varicose veins and nocturnal leg cramps and their gender differences. These findings will contribute to knowledge of gender-specific occupational risk factors for symptoms in the distal lower extremities.
在韩国人群中探讨职业特征与静脉曲张和夜间腿部痉挛症状之间的关系及其性别差异。
本研究人群为来自不同职业的 2165 名工人(55.6%为女性)。采用多因素逻辑回归分析方法揭示与静脉曲张和夜间腿部痉挛症状相关的因素。
女性静脉曲张和夜间腿部痉挛的患病率均高于男性。站立工作的特点因性别而异。在性别分层分析中,对于男性和女性工人,长时间站立的静脉曲张比值比显著较高。然而,只有长时间站立的男性工人夜间腿部痉挛的比值比才有统计学意义。按照性别、长时间站立和职业的顺序纳入模型后,模型显示职业纳入模型后,性别与静脉曲张之间无显著相关性。工作中长时间站立可能是静脉曲张和夜间腿部痉挛比男女之间的生物学差异更为重要的危险因素。因此,应实施有效的干预措施来中断或减少工作中的长时间站立,以预防静脉曲张和夜间腿部痉挛。
本研究表明职业特征与静脉曲张和夜间腿部痉挛症状之间存在关联,且存在性别差异。这些发现将有助于了解下肢远端与性别相关的职业危险因素。
