| Abstract:: |
| Objective To investigate the basic data of risk estimation of lung cancer among non-uranium miners in China. Methods 2836 workers from 24 mines in 9 provinces/regions were face-to-face interviewed to collect information including age at exposure, exposure duration, cigarette smoking among others. Results Age of the investigated non-uranium miners ranged from 17 to 72 (36.9±8.0) years. The miners received low and poor education, 3% of them were illiterate, 58% with primary and middle school education, only 7% with junior college and higher education. Seventy-five percent of the uranium miners are migrant rural workers. Ethnic minority miners accounted for 16% of all the investigated miners. Among the migrant rural workers age at initial exposure was estimated to be 29.6±8.0 years. By the time of the investigation, 46.7% of the miners had worked in the mine for five years and longer, working years in the mine was 6.7±6.8 years with a median of 4.1years. 3.4% of the non-uranium miners began the initial radon exposure in mines before their 18 years of old. 17.5% of the investigated miners reported working more than 8 h every working day. Among the males, 58.0% were current smokers with a median of 16 cigarettes per day. Age to begin the cigarette smoking was 20 years on average. Current smoking rate was age-dependent, the rate as high as 69.2% for the males aged 15-19 years. Current smoking rate was significantly statistically lower in coal mines than that in other mines, 49.0% vs 62.5%. Compared with other miners, more frequent mechanical ventilations were reported by coal miners.Conclusion In China non-uranium mines, 75% were migrant rural workers, by the time of the investigation about half of them had worked in the mines for at least five years. Non-uranium miners began their mining at 30 years on average, with a very small percentage of 3%, exposed to the mining radon before their 18 years. Current cigarette smoking rate in non-uranium male miners was the same as the general male population in China. |
