      Aim: To determine the association between postural overload and low back pain in combis’ (van) drivers of a public transport company. Materials and Methods: A cross-sectional study among 208 “combi” drivers was conducted. Nordic Kuorinka Questionnaire, Bus Drivers Job Demands Scale, Rapid Upper Limb Assessment Scale (RULA) were administered. Poisson regression with robust variance and crude and adjusted Prevalence Ratios (PR) with 95% CI were compute. Results: The prevalence of low back pain was 79.33% and postural overload was associated with low back pain according to RULA, level 3 (PR 1.44 [95% CI 1.05-1.99]) and level 4 (PR 1.72 [IC 95% 1.27-2.32]) with respect to drivers with level 2, after adjustment for body mass index (BMI), age, years of work as a driver and daily hours of work. Conclusion: Drivers who had postural overload had more probability to present low back pain
