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.

Background: Healthcare workers infected with Hepatitis B (HBV) or Hepatitis C virus (HCV) may undertake patient care activities if provider-to-patient transmission risks have been assessed in terms of viral load and clinical procedures. The present study investigated potential barriers to the acceptance of colleagues infected with HBV/HCV in healthcare settings after appropriate risk assessment. Methods: We conducted an anonymous, internet-based survey of Japanese nurses. Multivariate logistic analysis was used to assess factors associated with willingness to accept colleagues infected with HBV/HCV after risk assessment. Results: In total, 992 nurses responded to the survey, with 16% indicating that colleagues infected with HBV/HCV should not have patient contact after risk assessment. Willingness to accept HBV/HCV-infected colleagues was negatively associated with attitudes regarding the avoidance of contact with HBV/HCV-infected colleagues (OR: 0.49; 95% CI: 0.28-0.85). Previous professional contact with HBV/HCV patients (OR: 1.73; 95% CI: 1.36-2.12), experience of accidental injection from or personal exposure to HBV/HCV patients (OR: 2.00; 95% CI: 1.42-2.61), knowledge of HBV/HCV (OR: 2.00; 95% CI: 1.52-2.49), and female sex (OR: 1.60; 95% CI: 1.17-2.09) were positively associated with a willingness to accept HBV/HCV-infected colleagues. Conclusions: This study suggests that attitudes regarding the avoidance of contact with HBV/HCV-infected colleagues may be barriers to accepting these colleagues even after risk assessment has been performed. To protect the employment of nurses infected with HBV/HCV, employers should provide comprehensive education for nurses to reduce stigma and improve understanding about the management of staff infected with infectious diseases, such as HBV or HCV.

This study aimed to determine the prevalence and risk factors associated with respiratory symptoms. A cross-sectional study with random sampling method was employed and 300 home-based garment workers (HBGWs) were recruited. Risk factors, including personal factors; knowledge, health preventive behaviors, and skill of self-health surveillance, working condition, and respiratory symptoms were assessed. Data were collected using self-reported questionnaires. Prevalence of respiratory symptom was 22.3%. Majority of participants were female (78%). Mean age and working experience were 37.38 years (SD = 10.70) and 13.58 years (SD = 8.71), respectively. Allergic respiratory symptoms (odds ratio [OR] = 16.5; 95% confidence interval [CI] = 8.61-31.7) and garment dust exposure (OR = 12.3; 95% CI = 6.49-23.3) were significantly associated with respiratory symptoms (P < .001). Logistic regression analysis indicated history of allergic predicted the respiratory symptoms (OR = 12.96; 95% CI = 4.24-39.55). HBGWs who had serious allergic symptoms and high exposure to dust were at risk of respiratory symptoms. Therefore, preventive program for garment dust exposure among HBGWs is needed.
