OBJECTIVES
To test
associations between non-specific low back pain and several risk
factors when definitions of low back pain vary.
DESIGN/SETTING/PARTICIPANTS
A cross
sectional study was set up in 1991, 725 workers from four occupational
sectors answered a self administrated questionnaire including the
Nordic questionnaire and questions about intensity of pain and
individual and occupational factors.
MAIN
RESULTS
Prevalence of low back pain varied from
8% to 45% according to the definition used. Psychosomatic problems,
bending or carrying loads were often associated to low back pain,
whereas other risk factors were related to some specific dimensions of
the disorder.
CONCLUSIONS
Risk
factors of low back pain vary with the definition. This could explain
inconsistencies found in literature reviews. To be able to compare
data, it seems important to be precise what definition is used and to
use comparable questionnaires.
