[Investigation on the health status of workers exposed to dimethylformamid].

Objective: By analyzing the examination results of physical examination of workers exposed to DMF among 32 factories in some areas of a province, to investigate the working years of dimethylformamide (DMF) poisoning and the impact on the health status of exposed workers, and to explore the targeted intervention strategies. Methods: From February to May 2018, 2, 457 workers exposed to DMF in some areas of Jiangsu Province were selected as survey targets. Cross-sectional survey was conducted to investigate the health status of workers exposed to health, And the health surveillance data, detection data of occupational disease risk factors in the workplace were collected and analyzed, respectively. Results: The positive rate of abnormal liver function and B-ultrasound of males exposed to DMF was significantly higher than that of females. The abnormal rates of liver function, blood pressure and B-ultrasound in workers aged between 60 and 69 were higher in contrast to those in any other age groups. And the differences was statistically significant. In particular, the highest rate of abnormal blood pressure was found in workers exposed 21-30 years (39.2%) , the highest rate of abnormal liver function was found in workers exposed 11-20 years (44.3%) , and the highest rate of abnormal B-ultrasound was found in workers exposed 0-10 years (60.4%) . Conclusion: Long-term exposure to dimethylformamide can affect workers' liver function and blood pressure. Specifically, with the increase of contact age, the degree of chronic damage to liver, cardiovascular and other organs also increases.
