P-315 Occupational Risk Assessment of Lower Back Pain for Industry Workers

Abstract Introduction To estimate the influence of occupational factors on prevalence and risks of development of lower back pain (LBP). Methods Occupational risk related to LBP has been analyzed based on the results of medical examinations of 3215 industry workers and odds ratio (OR) for LBP has been calculated. Results Male workers in the age of 30 to 50 with a length of service of 10-15 years have greater risk of developing LBP. Other important factors contributing to the development of lower back pain disorders are weight lifted, body tilt (OR =1,89 (95% CI 1,39-2,56), whole-body vibration (OR =2,9 (95% CI 2,3-3,8). Although the most damaging impact is made by continuous workload during workshift, lifting and carrying heavy loads by hand (OR =2,2 (95% CI 1,8-2,7), continuous sitting or standing in the same working posture are also considered to be risk factors for LBP (OR= 1,42 (95% CI 1,20- 1,67). Discussion We have determined that the sitting posture per se does not affect the prevalence of LBP whereas a combination of continuous sitting posture of more than 180 minutes per day, awkward working posture and exposure to whole-body vibration increase the risk of back pain considerably. Conclusion Furthermore, an IPAQ-based study of physical activity at leisure and work shows that the prevalence of LBP is affected by both - by insufficient or vigorous physical activity at work, as well as physical inactivity at leisure, which increases the risk of LBP (OR= 1.5 (95% CI 1.1-2.1).
