Standing at work has been associated with discomfort and cardiovascular symptoms. Because standing postures vary in duration, mobility, and constraint, we explored associations between specific postures and pain in the lower extremities.
We used multiple logistic regression to analyze associations between work factors and pain in the lower extremities during the previous 12 months that interfered with usual activities. We used data from among 7757 workers who were interviewed in the 1998 Quebec Health and Social Survey.
Among all respondents, 9.4% reported significant ankle or foot pain, and 6.4% had lower-leg or calf pain. Significantly more women than men had pain at both sites. Both leg or calf and ankle or foot pain were strongly associated with standing postures, whole-body vibration, psychological distress, female gender, and being aged 50 years or older. Constrained standing postures were associated with increased ankle or foot pain for both men and women and with leg or calf pain for women, compared with standing with freedom to sit at will.
Freedom to sit at work may prevent lower-extremity pain. The effects of specific sitting and standing postures on cartilage, muscle, and the cardiovascular system may help explain discomfort in the lower extremities.
站立工作与不适和心血管症状相关。由于站立姿势在持续时间、活动度和受限程度上存在差异，我们探讨了特定姿势与下肢疼痛之间的关联。
我们使用多元逻辑回归分析工作因素与过去12个月内干扰日常活动的下肢疼痛之间的关联。我们使用了1998年魁北克健康与社会调查中7757名工人的访谈数据。
在所有受访者中，9.4%报告有明显的脚踝或足部疼痛，6.4%有小腿或小腿肚疼痛。女性在这两个部位疼痛的比例明显高于男性。小腿或小腿肚疼痛以及脚踝或足部疼痛均与站立姿势、全身振动、心理困扰、女性性别以及年龄在50岁及以上密切相关。与可以随意就坐的站立姿势相比，受限的站立姿势会增加男性和女性的脚踝或足部疼痛，以及女性的小腿或小腿肚疼痛。
工作时能够就坐可能预防下肢疼痛。特定的坐立姿势对软骨、肌肉和心血管系统的影响可能有助于解释下肢的不适。
