[The coverage of work injury insurance and its affecting factors in Zhejiang province, China].

OBJECTIVE
In China, the coverage rate of work injury insurance was 23.2%in 2011, which was far lower than expected. The factors affecting the insurance's enrollment has very little known. This paper aims to study the existing coverage of work injury insurance scheme and its influencing factors.


METHODS
The data were collected from 2 836 workers who came from 9 industries in three cities of Zhejiang province using face-to-face questionnaire interview.


RESULTS
Of these 2836 workers, the work injury insurance coverage was 50.1%, and 29.6% were not sure if they were covered or not. The results showed that the awareness of occupational disease and industrial injury insurance was helpful in increasing the coverage rate. Besides, the logistic regression analysis showed that in certain circumstances working population shared higher coverage of work injury insurance. For examples, male workers with local household registration and longer working years; people who had been informed about occupational risk factors, and thus gained more training on the issue; people who had exposed to occupational hazards or involved in administrative duties; and people who had already insured by a medical insurance scheme. In the contrary, the heavier family burden with longer working hours per week they needed, the lower possibility they joined the insurance scheme.


CONCLUSIONS
The coverage of work injury insurance is higher than native average level but much lower than the average international level. The awareness of occupational disease and injury insurance was closely associated with the coverage of work injury insurance. Therefore, it is imperative to popularize the knowledge on OHS for migrant workers, as well as to reinforce the supervision and management of the issue would have been an effective way to elevate the coverage rate of work injury insurance.
