Abstract
Objective: The objective of this study was to evaluate the prevalence of low back pain among bus drivers and to investigate the existence of a relationship between low back pain and psychosocial factors. Methods: We used an epidemiologic self-administered questionnaire, validated and adapted from the Quebec Back Pain Disability Scale. The sample included 78 male bus drivers, with mean age of 32.5 years. Results were analyzed through descriptive statistical methods (mean, median, standard deviation, standard error and coeffi cient of variation). Inferential analyses were performed with the Kolmogorov-Smirnov test, to analyze normality and with the Spearman correlation to determine the correlation among variables, with a confi dence level of p<0.05. Results: Low back pain showed a prevalence of 33.4%, and a low average correlation was observed among the variables. Conclusion: Around 34% of urban bus drivers reported low back pain, and the variables analyzed showed medium low correlation.
