OBJECTIVE
The causes of low back pain in China and Western countries are extremely different. We attempted to analyze the risk factors of low back pain in urban and rural patients under the dual economy with the simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ) to demonstrate that SC-RMDQ could evaluate patients with low back pain arising from different causes.
METHODS
Roland-Morris disability questionnaire was translated into SCRMDQ according to international guidelines for questionnaire adaptation. In this study, causes of low back pain of 187 outpatients and inpatients (99 urban patients and 88 rural patients) were analyzed. All patients underwent simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ), simplified Chinese Oswestry disability index (SCODI) and visual analogue scale (VAS). Reliability was tested using reproducibility (intraclass coefficient of correlation--ICC) and internal consistency (Cronbach's alpha). Validity was tested using Pearson correlation analysis.
RESULTS
The leading causes for low back pain were sedentariness (38.4%) and vibration (18.1%) in urban patients and waist bending (48.9%) and spraining (25%) in rural patients. Although causes of low back pain in the two groups of population were completely different, SCRMDQ had high internal consistency (Cronbach's α value of 0.874 in urban patients and 0.883 in rural patients) and good reproducibility (ICC value of .952 in urban patients and 0.949 in rural patients, P<0.01). SCRMDQ also showed significant correlation with Simplified Chinese version of Oswestry disability index (SCODI) and visual analogue scale (VAS) in rural areas (SCRMDQ-SCODI r = 0.841; SCRMDQ-VAS: r = 0.685, P<0.01) and in urban areas (SCRMDQ-SCODI: r = 0.818, P<0.01; SCRMDQ-VAS: r = 0.666, P<0.01).
CONCLUSIONS
Although causes of low back pain are completely different in rural and urban patients, SCRMDQ has a good reliability and validity, which is a reliable clinical method to evaluate disability of rural and urban patients.
目的
中西方腰痛的病因截然不同。我们试图通过使用简化中文版 Roland-Morris 残疾问卷（SC-RMDQ）分析城乡患者的腰痛危险因素，以证明 SC-RMDQ 可用于评估不同病因所致腰痛患者的病情。
方法
根据问卷汉化指南将 Roland-Morris 残疾问卷译为 SC-RMDQ。本研究纳入 187 例门诊和住院患者（99 例城市患者和 88 例农村患者），均采用 SC-RMDQ、简化中文版 Oswestry 残疾指数（SCODI）和视觉模拟评分法（VAS）进行评估。采用组内相关系数（ICC）评估重测信度，采用克朗巴赫系数（Cronbach's α）评估内部一致性。采用 Pearson 相关分析评估效度。
结果
城市患者腰痛的主要病因是久坐（38.4%）和振动（18.1%），农村患者腰痛的主要病因是弯腰（48.9%）和扭伤（25%）。虽然两组人群腰痛的病因完全不同，但 SC-RMDQ 具有较高的内部一致性（城市患者 Cronbach's α 值为 0.874，农村患者为 0.883）和良好的重测信度（城市患者 ICC 值为 0.952，农村患者为 0.949，P<0.01）。在农村地区，SC-RMDQ 与简化中文版 Oswestry 残疾指数（SCODI）和视觉模拟评分法（VAS）显著相关（SC-RMDQ-SCODI：r=0.841；SC-RMDQ-VAS：r=0.685，P<0.01），在城市地区也具有显著相关性（SC-RMDQ-SCODI：r=0.818，P<0.01；SC-RMDQ-VAS：r=0.666，P<0.01）。
结论
尽管城乡患者腰痛的病因完全不同，但 SC-RMDQ 具有良好的信度和效度，是评估城乡患者残疾程度的可靠临床方法。
