Background:
farming requires high physical effort and awkward postures, which are low back pain risk factors and restrain work. Low back pain, particularly chronic pain, causes a high number of sick leaves.
Objective:
to assess prevalence of work limitations due to chronic low back pain (CLBP), of low back pain in the last month (LBPLM) and of acute low back pain (ALBP), as well as the tasks farmers, owing to these injuries, are not able to cope with.
Methods:
cross-sectional study carried out in 2011 in a random sample of Brazilian tobacco farmers (2469) from São Lourenço do Sul/RS. Factors associated to limitation originated from LBPLM were evaluated via Poisson regression.
Results:
prevalence of work limitation due to CLBP, LBPLM and ALBP were respectively 37.6%, 14.4% and 7.8%. The tasks tobacco farmers most frequently had to give up were: carrying leaves, stacking firewood and harvesting bottom leaves. In the adjusted analysis, age, road tax expenses, difficulty in paying debts and minor psychiatric disorders were associated to work limitation due to LBPLM. ALBP individuals give up performing the same tasks as CLBP individuals, but CLBP individuals have higher work limitations.
