张家港市1980年前从事放射工作人员肿瘤流行病学调查结果分析

Analysis of epidemiological findings of tumor among workers engaged in radiation work before 1980 in Zhangjiagang City

目的通过对张家港市1980年前从事放射工作人员肿瘤流行病学调查结果进行分析,旨在为放射性疾病的防治提供依据。方法采用病例对照的方法,通过问卷调查,探索该市从事放射工作人员的肿瘤的发生及死亡情况与射线接触的关系。结果放射组和对照组肿瘤发生率及死亡率没有统计学上的差异(P>0.05)。总体上,由于接触放射因素,使得放射组肿瘤和死亡发生的危险性提高;按照性别分层,使得男性肿瘤和死亡的危险性会增加;按照年龄分层,在对照组人群中,≤69岁者肿瘤及死亡的发生危险性较高,而放射组人群≤69岁者死亡发生的危险性较高,>69岁的肿瘤发生的危险性较高。结论由于接触放射因素,使得放射组肿瘤发生和死亡发生的危险性都较对照组高。

[ Objective] To analyze the epidemiological findings of tumor among workers engaged in radiation work before 1980 in Zhangjiagang City, and provide evidence for prevention and treatment of radiation sickness. [ Methods ] Case-control study was a- dopted to explore the association between ray exposure and tumor morbidity and mortality among radiation workers in Zhangjiagang City via questionnaire survey. [ Results ] The tumor morbidity and mortality was not significantly different between radiation group and control group （ P 〉 0.05 ）. In general, due to exposure to radiation factors, the risk of tumor morbidity and mortality was signifi- cantly increased. Stratified according to gender, the risk of male tumor morbidity and mortality was increased. Stratified by age, the risk of tumor morbidity and mortality was relatively high among workers ≤ 69 years in control group, while in radiation group the risk of tumor mortality and morbidity was relatively high in workers ≤ 69 years and workers 〉 69 years, respectively. [ Conclusion] Due to exposure to radiation factors, the risk of tumor morbidity and mortality is higher in radiation group than in control group.
