Manual Handing as Risk Factor of Low Back Pain Among Workers
Disorders of the musculoskeletal system constitute a comsiderable health problem in industrialized societies. Low back pain (LBP) remain a comon and costly problem among the workers. Worplace injuries, primarily musculoskeletal disorder, are a pesistent problem for nursing. A cross-sectional study was conducted to invesgate prevalence of LBP as well as the potential risk factors associated with LBP. These potential risk factors include individual characteristics,job duratio, type of work, and manual handling knowledge and practice. Severy-six subjects consisting of 30 nurses and 46 administrative workers were recruited into the study. Symptoms of LBP cases were assessed by means of a simple questionnaire, and the diagnosis of LBP was confirmed by clinical examination. The study showed that the overall point prevalence rate of LBP was 42.1% while the overall 12 month prevalence rate was 69.7%. Occupational group and manual handling practice were independent predictors for point prevalence of LBP. Nursing occupation significantly the risk of point prevalence rate of LBP by 2.703 (95% C.I. OR 1.046-6.984) compared to administrative workers Nurses with frequent manual hendling practice had a 2.917-fold hugher risk of developing a point prevalence of LBP, although this risk was statistically not significant (OR=2.917,95% C.I. 0.094-3.003). The study indicates that an association exists between manual handing pracice and LBP prevalence.
