Work conditions in agriculture as risk factors of spinal pain in postmenopausal women.

The aim of the study was to evaluate the risk factors for spinal pain in Polish, postmenopausal women, working in agriculture. The study included 1751 randomly selected postmenopausal women aged 45-65. The women were exposed to hazardous work conditions, in particular the use of force, heavy lifting, often more than 10 kg and with frequency of at least once a day. Two-thirds of them suffered from spinal pain, mostly in the lumbar, less frequently in cervical and thoracic spine. The prevalence of spinal pain depended on exposure to health risks associated with overwork, early onset of menopause and increasing age. The prevalence of pain in lumbar spine correlated positively with higher frequency of heavy lifting and using excessive force during agricultural work. The severity of spinal pain correlates positively with the age of pain onset and negatively with level of education.
