The purpose of this study was to develop a conceptual model for the association between various biopsychosocial factors and nonspecific low back pain (LBP) in a sample of office workers.
A 1-year prospective cohort study of 669 healthy office workers was conducted. At baseline, a self-administered questionnaire and standardized physical examination were employed to gather biopsychosocial data. Follow-up data were collected every month for the incidence of LBP. A regression model was built to analyze factors predicting the onset of LBP. Path analysis was performed to examine direct and indirect associations between identified risk factors and LBP.
The onset of LBP was predicted by history of LBP, frequency of rest breaks, and psychological demand, measured by the Job Content Questionnaire. All 3 factors directly related to LBP; history of LBP was the strongest effector on the onset of LBP. History of LBP and frequency of rest breaks had indirect effects on LBP that were mediated through psychological demand, and frequency of rest breaks was the most influential effector on psychological demand.
Three risk factors were identified to predict onset LBP, including history of LBP, frequency of rest breaks, and psychological demand. Each factor had direct effects on the development of LBP. Also, history of LBP and frequency of rest breaks had indirect effects on LBP that were mediated through psychological demand.
本研究旨在为办公室工作人员样本中各种生物心理社会因素与非特异性下背痛（LBP）之间的关联建立一个概念模型。
对669名健康办公室工作人员进行了为期1年的前瞻性队列研究。在基线时，采用自我管理问卷和标准化体格检查来收集生物心理社会数据。每月收集随访数据以了解LBP的发病率。建立回归模型以分析预测LBP发作的因素。进行路径分析以检查已确定的风险因素与LBP之间的直接和间接关联。
LBP的发作可通过LBP病史、休息频率和心理需求来预测，心理需求通过工作内容问卷进行测量。所有这三个因素都与LBP直接相关；LBP病史是LBP发作的最强影响因素。LBP病史和休息频率对LBP有间接影响，这种影响通过心理需求介导，休息频率是对心理需求最有影响的因素。
确定了三个预测LBP发作的风险因素，包括LBP病史、休息频率和心理需求。每个因素对LBP的发展都有直接影响。此外，LBP病史和休息频率对LBP有间接影响，这种影响通过心理需求介导。
