A relationship between low back pain (LBP) and prolonged standing or prolonged sitting at work has not been clearly shown, despite its biological plausibility. Because sitting and standing postures vary as to duration and freedom to alternate postures, and standing postures vary as to mobility, associations between specific working postures and LBP were explored using multiple logistic regression. Associations between work factors and self-reported LBP during the previous 12 months that interfered with usual activities were examined among 4493 standing workers and 3237 sitting workers interviewed in the 1998 Quebec Health and Social Survey; 24.5% reported significant LBP. Since the same conditions can correspond to different physiological demands for sitting compared with standing workers, analyses were performed separately for the two groups. Standing without freedom to sit was associated with LBP. Different occupational physical and psychosocial factors were associated with LBP in sitting compared with standing populations.
尽管从生物学角度来看，工作中长时间站立或久坐与下背痛（LBP）之间存在关联，但这种关联尚未得到明确证实。由于坐姿和站姿的持续时间和交替姿势的自由度不同，站立姿势的活动度也不同，因此使用多变量逻辑回归方法探讨了特定工作姿势与 LBP 之间的关联。1998 年魁北克省健康与社会调查采访了 4493 名站立工作者和 3237 名坐姿工作者，调查了过去 12 个月中干扰日常活动的工作因素与自我报告的 LBP 之间的关系；24.5%的人报告有明显的 LBP。由于相同的条件可能对应于坐姿和站立工作者不同的生理需求，因此对这两组分别进行了分析。无法自由坐下的站立与 LBP 有关。与站立人群相比，不同的职业体力和心理社会因素与坐姿人群的 LBP 相关。
