Objectives: to estimate the influence of occupational factors on prevalence and risks of development of LBP.
Мethods: Investigation of prevalence and occupational risk factors (odds ratio (OR) of development of LBP syndrome has been based on the results of medical examination of 2887 industry workers. International Physical Activity Questionnaire was filled with 1478 patients  (IPAQ) (AinsworthB.E., etal. 2000). 
Results: The results show a significant effect of length of service and age on the prevalence of LBP. Workers aged 40 to 50 have a greater risk of developing LBP. The greatest risk of LBP was detected in workers with a length of service more than 15 years. With cervical spine pain (OR =3.37 (95% CI 2.8-4.06), joint disorders (OR= 4.83 (95% CI 3.95-5.91) or respiratory diseases (OR= 3.3 (95% CI 2.55-4.26) present, the risk of developing LBP increases dramatically. Another important factor contributing to the development of lower back pain disorders is the exposure to whole-body vibration (OR =1.84 (95% CI 1.47-2.29) or local vibration (OR =1.87 (95% CI 1.50-2.33). The biggest impact is made by work-related dynamic activity (OR =5,22 (95% CI 3,5-7,81), lifting and carrying heavy loads by hand (OR =3,01 (95% CI 2,41-3,75). 
An IPAQ-based study of  work-related and leisure-time physical activity has yielded interesting results: the prevalence of LBP is affected by insufficient or vigorous physical activity. 
Insufficient physical activity (hypodynamia) at work comparatively increases the risk of developing back pain as well as physical overstrain (OR= 1,82 (95% CI 1,33-2,49).
Combination between leisure-time physical inactivity (hypodynamia) and high-level work-related physical activity (physical overstrain) definitely increases the risk of LBP (OR= 2.95 (95% CI 1.592-5.488). 
At the same time, there was found no evidence that the co-occurring conditions of endocrine system, gastrointestinal tract, urinary system or cardiovascular diseases interfere with the probability of lumbar pain syndromes in industry workers.
