橡胶制品工业恶性肿瘤死亡率流行病学调查

An epidemiological survey of the mortality of malignancy in the rubber industry

本文报告橡胶制品工业恶性肿瘤死亡率情况。采用回顾性队列流行病学研究方法,共调查3 573人,3 455人进入队列,失访率为3.3％,得67 693人年。1965～1984年间共死亡346人,其中恶性肿瘤占33.2％,为全部死因之首。全部职工和男性职工全癌死亡、肝癌死亡、膀胱癌死亡与当地居民比较相差具有显著意义。按工种分析,压胶工种恶性肿瘤SMR191,P<0.05。将全部职工分为直接接触组和间接接触组分析比较,直接接触组肝癌和膀胱癌的死亡率高于间接接触组。

The method of retrospective cohort studiesis applied to survey the mortality of malig-nant tumours in the rubber industry. Therewere 3573 workers investigated. The cohort con-sisted of 3455 workers, and had an accumula-tion of 67693 person-years. Missing follow-uprate was 3.3 per cent. There were 346 deaths from 1965 to 198433.23 per cent died of malignancies and werethe first cause of death. Deaths of total can-cers, liver cancer, and bladder cancer amongall workers and male workers comparedwith the inhabitant were statistically signifi-cant, Analysis by the kinds of working, SMRfrom the malignancy among compressed rubber's workers was 191 (P<0.05). All wrkeorswere classified into direct exposed group andindirect exposed group. The results showedthat the mortatities of liver cancer and bladdercancer in direct exposed group were higherthan in indirect exposed group.
