The study population was 499 (the response rate was 92%). 27 questionnaires were excluded due to incomplete or missed information. The rest were 472 drivers, 141 of them disclose back pain in the previous 3.12 month, giving prevalence of 29.9%. From those with back pain 92% deny any other health problems that affect their back. 82% of them described their pain as mild. 80.9% mentioned that minor physical activity does not make their pain worse. 87.2% declare that, they can do light work for an hour without pain being a problem.In this study some occupational factors have been investigated with relation to back pain in professional drivers. It shows that, working hours >8 hours per day, working days >5 days per week and years of driving >10 years, are significantly associated with increased back pain in professional drivers (p value 0.004) less than 0.05. It also shows that prevalence of back pain increases with long distance driving (p value 0.001). Other factors such as BMI >25 is also associated with increased risk of back pain in professional drivers.
