To examine the role of pain experiences in relation to work absence, within the context of other worker health factors and workplace factors among Canadian nurses with work-related musculoskeletal (MSK) injury.
Structural equation modeling was used on a sample of 941 employed, female, direct care nurses with at least one day of work absence due to a work-related MSK injury, from the cross-sectional 2005 National Survey of the Work and Health of Nurses.
The final model suggests that pain severity and pain-related work interference mediate the impact of the following worker health and workplace factors on work absence duration: depression, back problems, age, unionization, workplace physical demands and low job control. The model accounted for 14 % of the variance in work absence duration and 46.6 % of the variance in pain-related work interference.
Our findings support a key role for pain severity and pain-related work interference in mediating the effects of workplace factors and worker health factors on work absence duration. Future interventions should explore reducing pain-related work interference through addressing workplace issues, such as providing modified work, reducing physical demands, and increasing job control.
在加拿大患有与工作相关的肌肉骨骼（MSK）损伤的护士中，研究疼痛经历与工作缺勤之间的关系，考虑到其他工人健康因素和工作场所因素。
使用结构方程模型对 941 名从事直接护理工作的女性护士进行分析，这些护士因与工作相关的 MSK 损伤而缺勤至少一天，数据来自于 2005 年全国护士工作与健康横断面调查。
最终模型表明，疼痛严重程度和与疼痛相关的工作干扰中介了以下工人健康和工作场所因素对工作缺勤持续时间的影响：抑郁、背部问题、年龄、工会化、工作场所物理需求和低工作控制。该模型解释了工作缺勤持续时间方差的 14%和与疼痛相关的工作干扰方差的 46.6%。
我们的研究结果支持疼痛严重程度和与疼痛相关的工作干扰在中介工作场所因素和工人健康因素对工作缺勤持续时间的影响方面发挥关键作用。未来的干预措施应该通过解决工作场所问题来探索减少与疼痛相关的工作干扰，例如提供修改后的工作、减少体力需求和增加工作控制。
