The prevalence of low back pain showed increment in the point prevalence of 57.9%, 49.5%, and 35.1 % for 12 months, one month, and of 7 days respectively. Working hour, frequency of overtime, stress at work, work pace, and faster movement were found to be significantly associated with the 12 months prevalence for low back pain.
Conclusions
This finding indicates that psychosocial risk factors are associated to the occurrence of low back pain.
