As a result, the total number of valid responses was 1,334 and the response rate was 71 percent, and the 1-wk prevalence of LBP was 20.5 percent of respondents. Regarding 275 subjects with LBP, Visual Analogue Scale (VAS) averaged 4.3. There was a positive weak correlation between VAS and Roland-Morris Disability Questionnaire score (R=0.41). And Logistic regression analysis was performed to examine the relationship between LBP and occupational factors, the results suggested following items as risk factors; such as history of LBP, suffering from fatigue, diseases other than LBP and smoking habit.
