Abstract
Introduction. The pain in the lower back (BCC) has a wide distribution among the working people’s age and is a frequent cause of temporary disability.
The identification of risk factors for the back pain is necessary to address expert issues and developing measures for prevention of incidence.
Materials and methods. There were studied prevalence odds ratio (OR) for the development of the low back pain (LBP) in two thousand nine hundred fifteen working patients with different indicators of hardness of the labour process and levels of physical activity (PA).
Results. According to the special assessment of the working conditions, the harmful (3rd) class of hardness of the labour process in comparison with the 1st and 2nd classes (optimal and permissible) increased the LBP prevalence from 31.6 to 37.1% with OR = 1.27 at 95% Ci (1.03–1.43), p <0.05. No reliable differences were obtained under comparing classes separately with the 1st class. According to the International questionnaire of physical activity, the LBP prevalence under an intensive PA is 29.3% with OR = 1.5 at 95% CI (1.6–2.11), at a low PA – 37.2% with OR = 2.15 at 95% Ci (1.07–4.3). The smallest LBP prevalence was revealed in a moderate PA mode throughout the day (21.6%).
Limitations. The present study has a limitation associated with the inconsistency of cards for special assessment of working conditions and the International questionnaire cards.
Conclusion. Data were obtained about the absence of reliable differences in the distribution and odds ratio for the development of LBP between workers by classes of hardness of the labour process. Workers with moderate and low PA have reliably low LBP prevalence.
