“…Office staff spent more time sitting yet their low back pain was more related to some non-occupational risk factors such as driving. Similar to the current study, Plouvier et al found a relationship between low back pain and work duration, flexion, extension, rotation and driving (10). The duration of low back pain was longer in clinical and the duration of absenteeism was longer among office staff, yet these differences were not significant.…”

Background: Some occupations have risk factors for chronic low back pain; clinical staff of hospitals are good examples for encountering many risk factors yet office staff encounter a few or may be at risk of unknown factors for occupational low back pain. Objectives: The objective of this study was to compare chronic low back pain frequency and risk factors between clinical and office staff. Patients and Methods: A cross-sectional study on clinical and office staff at hospitals was done by completing a questionnaire with interviews and a checklist. Data were analyzed with the SPSS software version 16 using chi-2, T-test and regression with significance level of P < 0.05. Results: No significant difference was observed between the two groups in terms of chronic low back pain; frequency of low back pain in clinical staff was 18% (18 individuals) and in office staff this was 17% (17 individuals) (P < 0.05). Chronic low back pain in the clinical group might be related to flexion and extension, twisting, pulling or pushing, carrying, handling of patients, and sitting (P value < 0.001), and in office staff it might be related to flexion and extension, twisting and long durations of time spent driving (P value < 0.001). Conclusions: Frequency of low back pain was not significantly different between clinical and office staff. Chronic low back pain in clinical staff was related to work while in office staff it was related to some occupational and non-occupational risk factors.

“…Lotters et al 9) showed that OR for frequent bending or twisting of the trunk was 1.68 (95%CI 1.41-2.01) on Meta analysis. Another recent study 37) showed that the association between twisting posture and LBP and ORs were distributed between 1.2 and 2.2. In comparison with these reports, our study showed a higher odds ratio 3.34 (95%CI 1.03-10.81).…”

Prevalence and Risk Factors of Low Back Pain among Thai and Myanmar Migrant Seafood Processing Factory Workers in Samut Sakorn Province, Thailand

et al. 2010

Low back pain (LBP) is one of the most common health problems all over the world. The lifetime prevalence of low back pain is reported to be over 70% in European countries and the peak prevalence occurred between ages 35 and 55 in the working population 1) . Despite its benign nature, LBP is the leading cause of disability and the highest cost for workers' compensation in industrialized countries [2][3][4][5][6] . In Thailand as well, high prevalence of LBP is reported. The six month prevalence of LBP was more than 50% in the study population over 50 yr old 7) .Risk factors for LBP have not been completely elucidated. The most frequently reported risk factor for LBP is heavy physical workload such as lifting, awkward posture, and whole body vibration [8][9][10] . Life style is also considered a risk factor of LBP. Smoking behavior 8,11,12) , lack of physical exercise 8) , and short sleep hours 13) increase the risk of LBP. A systematic review showed that there was no evident relationship between alcohol consumption and LBP 14) . An association between LBP and psychosocial factors has also been reported 8,15,16) . Food processing workers are known to be a high risk population for LBP because they work in awkward postures, with lifting and manual handling of heavy Received October 30, 2009 and accepted March 12, 2010 Abstract: This study assessed the prevalence of low back pain (LBP) and investigated risk factors for LBP among seafood processing factory workers in Thailand including migrant workers. The subjects were Thai and Myanmar workers in the typical seafood processing factory. A cross-sectional study was carried out with a self-administered questionnaire. Prevalence of LBP, general characteristics, life style, and working condition were investigated. The associations between LBP and risk factors were estimated by multiple logistic regression models. Of 254 workers, 165 completed the questionnaire. Half of these workers were Thai, the others were from Myanmar. The point prevalence of LBP was 28.5%. Risk factors for LBP were age over 40 yr, poor health status, history of back injury, twisting posture at work, and slipping on wet floors. The results suggest that health promotion should focus on working conditions rather than individual life style in order to prevent LBP. Furthermore, greater attention to other risk factors such as history of back injury and perception of health status after regular health check up, especially in older age groups may be needed.

“…In accordance with previous analyses, the duration of exposure was considered a quantitative variable (35). Each potential answer in the questionnaire, proposed as a category, was replaced by the value of its class center (ie, never=0, <10 years=5, 10-20 years=15, and >20 years=25).…”

Biomechanical strains and low back disorders: quantifying the effects of the number of years of exposure on various types of pain

Abstract: This study suggests that exposure to biomechanical strains has long-term effects and a dose-response relation with duration of exposure and specific effects for some types of LBP.
