Objective:
To investigate the prevalence of malignant tumor and its influencing factor among rubber workers in Hainan Province of China, and to study the high incidence of cancer and type of work.
Methods:
A retrospective cohort study on registered workers over 1 working age among partial rubber factories in Hainan Province in the period from 2005 to 2010.
Result:
There was a remarkable difference in the incidence between nature exposed rubber group and non-exposed group (χ(2) = 52.13,P < 0.01). Occupational exposure induced a high risk in malignant tumors (OR = 2.47, P < 0.05). The incidence of tumor may be associated with occupational exposure: the longer occupational exposure time, the higher was the incidence of tumor (χ(2) = 11.40, P < 0.05).
Conclusions:
The occupational exposure in rubber workers can induce a high incidence of malignant tumor.
