[Low back pain prevalence of female workers in flat-grained veneer wood industry].
OBJECTIVE
To study the low back pain(LBP) and its cause on female workers in flat-grained veneer wood industry.


METHODS
Bending posture was analyzed by observation and the prevalence of low back pain was investigated by physical examination and questionnaire among 299 female workers.


RESULTS
The prevalence of fatigue compliant in selecting, remending and sticking workers was 68.8%, 66.7% and 59.0%, respectively, which mainly involved in the part of low back. The prevalence of low back pain in selection (53.8%) and remending (58.7%) workers was higher than that in sticking workers (30.1%), which was in accordance with the tenderness between L4/L5 or L5/L6 and on the psoas major. Posture analysis indicated that the biggest bending range of selecting and remending workers (80 degrees ) was larger than that of sticking workers (60 degrees ), as well as the daily bending times[(4396+/-817), (1696+/-286), (1094+/-476)] and the time they kept bending[(6.5+/-0.6), (6.2+/-1.3), 4.5+/-0.9) h].


CONCLUSIONS
Bending posture is common among female workers especially those who work in selecting and remending and might be the major causes for the high prevalence of LBP in flat-grained veneer wood industry.
