Abstract

295 male Finnish concrete reinforcement workers, aged 19-64 years and engaged in heavy physical work including prolonged stooping, were clinically examined in a cross-sectional study. A history of sciatica was reported by 42% of the men, and a history of lumbago by 33%. The prevalence of the reported experience of sciatica and lumbago doubled in the two decades from age 25-34 onward. Half of those with a history of sciatica had also experienced lumbago; two-thirds of those who reported a history of lumbago had also suffered from sciatica. Back symptoms during an ordinary workday were reported as follows: ache 51%, fatigue 47%, stiffness 41% and sharp pain 13%. The correlation between the four symptoms was slight. Ache (χ2 = 23.5, p<0.001) and stiffness (χ2 12.0, p<0.001) were more common in workers with a history of sciatica than in workers without a history of lumbago or sciatica. In the analysis of the results for a possible effect of reinforcement work on back morbidity, the occurrence of back symptoms and syndromes was not found to be associated with length of reinforcement work, while comparison of a history of low-back pain syndromes between reinforcement workers and computer technicians showed experience of sciatica to be somewhat more common in the reinforcement workers (χ2 = 5.2, p<0.05).
