Objectives: The objective of this study was to investigate the experience and point prevalence rate and factors related with Low Back Pain (LBP) in bus drivers. Methods: Questionnaires were completed by 200 drivers at 2 bus companies in Andong city in October, 2000. The information was used to estimate odds ratio (OR) and 95% confidence intervals (CI) for factors relation to LBP. A cross-section study design was used. Results: The experience rate for LBP was 53.5%, point prevalence rate was 31.5%. Variables significantly associated with LBP experience were employ duration and stress related occupation. The higher subjects had experienced stress, the higher experience for LBP was (OR=2.9, 95% CI 1.2-7.2). The longer subjects had employ duration in bus company, the higher experience for LBP was (OR=1.3, 95% C1 1.2-7.2). Significant factors relation to a week point prevalence for LBP were obesity and employ duration. LBP increased as weight increased (OR=4.1, C1 1.6-10.7). The longer subjects has employ duration at bus company, the higher LBP is (OR=1.4, 95% C1 1.6-2.9). Conclusions: Results from this study indicated that a statistically significant factor relation to LBP was stress related occupation, employ duration, and obesity.
