Association between occupational health and safety knowledge and behaviours among migrant workers: Results from a cross-sectional study in China

Objectives To assess the relationship between occupational health and safety (OHS)-related behaviours of migrating workers in China and their knowledge regarding OHS laws and regulations (LRs) Materials and methods We sampled 1282 migrant workers from 12 labour-intensive manufacturers in Guangdong, China, with a response rate of 98.6%. Self-reported questionnaires were completed by the participants. Logistic regression models were used to examine the association between OHS-related behaviours and knowledge among migrant workers adjusting for their demographic features and the survey sites. Results Migrant workers' behaviour of seeking occupational disease (OD) diagnosis and treatment was found to be statistically significantly correlated with their knowledge of all three OHS LRs. A higher score of knowledge regarding these OHS LRs is associated with a better chance to seek OD diagnosis and treatment. The ORs of the high-score group (subjects correctly answered more than one question) versus the low-score group (subjects correctly answered less than or equal to one question) are 2.02 (95% CI: 1.33 to 3.07) for Law of Occupational Disease Prevention and Treatment, 2.89 (95% CI: 1.65 to 5.09) for Regulations on Safe Management of Dangerous Chemicals and Regulations on Labor Protection for Using Toxic Substances in Workplace and 2.25 (95% CI: 1.34 to 3.77) for Work-Related Injury Insurance Regulations. However, knowledge about these LRs is not statistically significantly associated with OHS-related protective behaviours such as wearing a mask or gloves at work. Conclusions Knowledge of OHS LRs helps migrant workers in China to seek OD diagnosis and treatment.
