The purpose of this study was to investigate the time dependent effects among factors affecting duration of work disability after compensated low-back pain. A postal survey involving 238 compensated workers at 39 companies was performed between January 5, 2004, and March 23, 2004. Cox proportional hazard regression analysis was used to model the effect of demographic, work-related, and injury factors affecting the duration of work disability. The variables that significantly affected the duration of work disability were age, company size, compensation benefit, pain radiation, and diagnosis. In addition, company size and pain radiation showed statistically significant time dependent effect. Consequently, this study found that there were time dependent factors affecting the duration of work disability. A phase-specific analysis would be useful to make policy for the prevention of long-term disability after back injury.
本研究的目的是调查影响代偿性下背痛后工作残疾持续时间的因素之间的时间依赖性效应。2004年1月5日至2004年3月23日期间，对39家公司的238名获得赔偿的工人进行了邮政调查。采用Cox比例风险回归分析来模拟影响工作残疾持续时间的人口统计学、工作相关和损伤因素的效应。显著影响工作残疾持续时间的变量有年龄、公司规模、赔偿福利、疼痛放射和诊断。此外，公司规模和疼痛放射显示出统计学上显著的时间依赖性效应。因此，本研究发现存在影响工作残疾持续时间的时间依赖性因素。特定阶段分析对于制定预防背部受伤后长期残疾的政策将是有用的。
