Little is known about the sick-leave experiences of workers who make a workers' compensation claim for back pain. Our objective is to describe the 1-year patterns of sick-leave and the health outcomes of a cohort of workers who make a workers' compensation claim for back pain. We studied a cohort of 1,831 workers from five large US firms who made incident workers' compensation claims for back pain between January 1, 1999 and June 30, 2002. Injured workers were interviewed 1 month (n = 1,321), 6 months (n = 810) and 1 year (n = 462) following the onset of their pain. We described the course of back pain using four patterns of sick-leave: (1) no sick-leave, (2) returned to worked and stayed, (3) multiple episodes of sick-leave and (4) not yet returned to work. We described the health outcomes as back and/or leg pain intensity, functional limitations and health-related quality of life. We analyzed data from participants who completed all follow-up interviews (n = 457) to compute the probabilities of transition between patterns of sick-leave. A significant proportion of workers experienced multiple episodes of sick-leave (30.2%; 95% CI 25.0-35.1) during the 1-year follow-up. The proportion of workers who did not report sick-leave declined from 42.4% (95% CI 39.0-46.1) at 1 month to 33.6% (28.0-38.7) at 1 year. One year after the injury, 2.9% (1.6-4.9) of workers had not yet returned to work. Workers who did not report sick-leave and those who returned and stayed at work reported better health outcomes than workers who experienced multiple episodes of sick-leave or workers who had not returned to work. Almost a third of workers with an incident episode of back pain experience recurrent spells of work absenteeism during the following year. Our data suggest that stable patterns of sick-leave are associated with better health.
对于因背痛提出工伤赔偿申请的工人的病假经历，我们知之甚少。我们的目标是描述一组因背痛提出工伤赔偿申请的工人的1年病假模式和健康状况。我们研究了来自美国五家大公司的1831名工人组成的队列，这些工人在1999年1月1日至2002年6月30日期间因背痛提出了工伤事故赔偿申请。受伤工人在疼痛发作后的1个月（n = 1321）、6个月（n = 810）和1年（n = 462）接受了访谈。我们使用四种病假模式描述了背痛的病程：（1）无病假，（2）返回工作岗位并继续工作，（3）多次病假，（4）尚未返回工作岗位。我们将健康状况描述为背部和/或腿部疼痛强度、功能受限以及与健康相关的生活质量。我们分析了完成所有随访访谈的参与者（n = 457）的数据，以计算病假模式之间转换的概率。在1年的随访期间，相当一部分工人经历了多次病假（30.2%；95%CI 25.0 - 35.1）。未报告病假的工人比例从1个月时的42.4%（95%CI 39.0 - 46.1）降至1年时的33.6%（28.0 - 38.7）。受伤1年后，2.9%（1.6 - 4.9）的工人尚未返回工作岗位。未报告病假的工人以及返回工作岗位并继续工作的工人报告的健康状况优于经历多次病假的工人或尚未返回工作岗位的工人。几乎三分之一的首次出现背痛的工人在接下来的一年中经历了反复旷工。我们的数据表明，稳定病假模式与更好的健康状况相关。
