Musculoskeletal symptoms (MSDs) in bus drivers have been associated to the inadequate conditions of the work station. The occurrence of MES was determined in the total population of bus drivers of a public university (N = 35), and these were related with the work station, the posture static load, age, BMI, worked days and the number of years in the position. In this study, the age range was between 27 and 56 years. The standardize Nordic Musculoskeletal Questionnaire for the determination of the MSDs, the method of the Regie National Des Usines Renault to measure the static postural load and a questionnaire to collect information of the bus working conditions were applied. The mean (X +/- SD) age was 39 +/- 1.94 years and the body mass index (BMI) was 31 +/- 1.95 Kg/m2. The MSDs were associated significantly to the BMI (rs = 0.895 and p < 0.05). There was a high incidence of MSDs (94%) with more occurrences in neck (69%), lower back (60%), superior back (57%) and knees (43%). Pain of strong intensity, located in the lower back and knees, was the main symptom. These findings can be related with the risks at the work station, such as absence of head support, lumbar support, non sliding seat and inadequate conditions of the labor environment: vibration and noise. There was neither association nor correlation of MSDs and the postural static load, or with the others variables in study. The results suggest that inadequate conditions of the work stations as well as the BMI, dominated the occurrence of MSDs.
