Abstract
Objective:
The
objective was
to
evaluate
the
efficacy
of
the
Revised
National Institute for Occupational Safety and Health (
NIOSH
)
lifting
equation
(RNLE)
to
predict
risk
of
low back
pain
(LBP). Background: In 1993,
NIOSH
published
the
RNLE as a
risk
assessment method for LBP
associated
with
manual
lifting
.
To
date, there has been little research evaluating the RNLE as a predictor
of
the
risk
of
LBP using a
prospective
design. Methods: A total
of
78 healthy industrial workers' baseline LBP
risk
exposures and self-reported LBP at
one-year
follow-up were investigated.
The
composite
lifting
index (CLI),
the
outcome measure
of
the
RNLE for analyzing multiple
lifting
tasks, was used as
the
main
risk
predictor.
The
risk
was estimated using
the
mean and maximum CLI variables at baseline and self-reported LBP during
the
follow-up. Odds ratios (ORs) were calculated using a logistic regression analysis adjusted for covariates that included personal factors, physical activities outside
of
work, job factors, and work-related psychosocial characteristics. Results:
The
one-year
self-reported LBP incidence was 32.1%. After controlling for history
of
prior LBP, supervisory support, and job strain,
the
categorical mean and maximum CLI above 2 had a significant relationship (OR = 5.1-6.5)
with
self-reported LBP, as compared
with
the
CLI below or equal
to
1.
The
correlation between
the
continuous CLI variables and LBP was unclear. Conclusions:
The
CLI > 2 threshold may be useful for predicting self-reported LBP. Research
with
a larger sample size is needed
to
clarify
the
exposure-response relationship between
the
CLI and LBP.
