Low back pain (LBP) is a common and major health problem. Although it is known that psychosocial factors are important predictors of LBP outcome, some factors, including financial compensation, have not been fully studied in Japan. This cross-sectional study aimed to examine the association between LBP compensation (workers' compensation and automobile insurance claims) and lifetime experience of chronic LBP and back pain disability (chronic disabling LBP) in a Japanese adult population.
In February 2011, 1,063,083 adults aged 20-79 years registered as Internet research volunteers were invited to complete an online questionnaire. We analyzed the data from 52,650 respondents who had ever experienced LBP. Multiple logistic regression analysis was used to examine the association between LBP compensation and lifetime experience of chronic disabling LBP, adjusting for age, sex, smoking habits, educational level, cause of LBP, history of radiating pain below the knee, and history of low back surgery.
Among the respondents, 2,039 (3.9 %) had experienced chronic disabling LBP. The prevalence of a history of receiving workers' compensation or automobile insurance claims was 1.1 % for each. In multiple logistic regression, the odds of chronic disabling LBP were significantly higher among those who received LBP-related compensation (workers' compensation or automobile insurance claims) compared with respondents who did not receive compensation.
The prevalence of compensated LBP was low. However, a history of compensated LBP was significantly associated with experiencing chronic disabling LBP.
腰痛是一种常见且主要的健康问题。尽管已知社会心理因素是腰痛预后的重要预测因素，但包括经济补偿在内的一些因素在日本尚未得到充分研究。这项横断面研究旨在探讨日本成年人群中腰痛补偿（工伤补偿和汽车保险索赔）与慢性腰痛的终生经历及背痛残疾（慢性致残性腰痛）之间的关联。
2011年2月，邀请了1063083名年龄在20 - 79岁之间注册为互联网研究志愿者的成年人完成一份在线问卷。我们分析了52650名曾经历过腰痛的受访者的数据。采用多元逻辑回归分析来检验腰痛补偿与慢性致残性腰痛的终生经历之间的关联，并对年龄、性别、吸烟习惯、教育水平、腰痛原因、膝以下放射性疼痛史以及腰椎手术史进行了调整。
在受访者中，2039人（3.9%）曾经历过慢性致残性腰痛。接受工伤补偿或汽车保险索赔的历史患病率均为1.1%。在多元逻辑回归中，与未获得补偿的受访者相比，获得与腰痛相关补偿（工伤补偿或汽车保险索赔）的受访者发生慢性致残性腰痛的几率显著更高。
获得补偿的腰痛患病率较低。然而，有获得补偿的腰痛病史与经历慢性致残性腰痛显著相关。
