At least 47% to 90% people will get low back pain in whole of his life. Most people ignored the influence and the impacts of the health that cause by the LBP. Actually, people will not die because of the LBP. But it will influence widely, especial the quality of life (QOL). The chronic LBP usually comes from acute stage. About 30% LBP patients will spend more than 80% of the costs that used on low back pain. The researches of chronic LBP will focus 4 aims: The severity of disease, the impact of the emotion, the disability that cause by LBP, and the influences of the QOL. The LBP has many risk factors and these assessments of the chronic LBP divides into 5 parts: the QOL, psychological factors, work relates, pain relates, physical factors. The Oswestry Disability Index, (ODI), Pain assessment of visual analog scale (P-VAS), 36-item short-form health survey (SF-36), Chinese Health Questionnaire (CHQ-12) are included. The data were for evaluating and finding the correlations between the quality of life, some scales and chronic LBP with multiple linear regressions and clustering technologies. The thresholds of these scales that define the chronic LBP are also presented. It included that ODI≧30, SF-36<375, CHQ-12≧2, GDS≧18 with significance (p<0.01). Build a model with these scales to predict the chance of being chronic LBP (R2=0.39). Including year-mean pain scale, the grades of feeling numbness, social functioning factor of SF-36 (SF-SF) and CHQ-12, these can well predict the chronic LBP with significance (p<0.1). And the ODI, CHQ-12 and P-VAS can present the QOL who has LBP (R2=0.59). We can almost confirm that the patient is only acute LBP if all of these scales remain near normal. Most patients (>80%) with LBP will not last for more than 7 days. The times of pregnant and BMI are both of the most important risk factors. The patients will more easy to have chronic LBP if you delivered the baby more than 3 times and BMI is higher than normal. Smoking is also another risk factors but there is no significant different between the chronic and acute LBP (p>0.1). Chronic LBP drink more tea or coffee than acute LBP with significant different (p<0.01). The less exercise and entertainments with chronic LBP compares with acute LBP and it is significant different (p<0.01). So it will decrease the chance of getting chronic LBP with regular exercise and proper entertainment.
