Zusammenfassung: | OBJECTIVE: Occupational low back pain (LBP) is considered to be the
most expensive form of work disability, with the socioeconomic costs of
persistent LBP exceeding the costs of acute and subacute LBP by far. This makes
the early identification of patients at risk of developing persistent LBP
essential, especially in working populations. The aim of the study was to
evaluate both risk factors (for the development of persistent LBP) and
protective factors (preventing the development of persistent LBP) in the same
cohort.
PARTICIPANTS: An inception cohort of 315 patients with acute to
subacute or with recurrent LBP was recruited from 14 health practitioners
(twelve general practitioners and two physiotherapists) across New Zealand.
METHODS: Patients with persistent LBP at six-month follow-up were
compared to patients with non-persistent LBP looking at occupational,
psychological, biomedical and demographic/lifestyle predictors at baseline
using multiple logistic regression analyses. All significant variables from the
different domains were combined into a one predictor model.
RESULTS: A final two-predictor model with an overall predictive
value of 78% included social support at work (OR 0.67; 95%CI 0.45 to 0.99) and
somatization (OR 1.08; 95%CI 1.01 to 1.15).
CONCLUSIONS: Social support at work should be considered as a
resource preventing the development of persistent LBP whereas somatization
should be considered as a risk factor for the development of persistent LBP.
Further studies are needed to determine if addressing these factors in
workplace interventions for patients suffering from acute, subacute or
recurrent LBP prevents subsequent development of persistent LBP. |
