Objective\ Low level of exposures to residential radon and dosimetric uncertainties due to mobility have hampered the evaluation of lung cancer risk and the comparison to radon\|exposed miners.To address these limitations,the authors conducted a case\|control study in a predominantly rural area of China with low mobility and high radon levels. Methods\ Cases studied including all lung cancer patients diagnosed between Ja nuary 1994 and April 1998,aged 30\|75 years,and resided in two prefectures of Gansu...

Objective\ Low level of exposures to residential radon and dosimetric uncertainties due to mobility have hampered the evaluation of lung cancer risk and the comparison to radon\|exposed miners.To address these limitations,the authors conducted a case\|control study in a predominantly rural area of China with low mobility and high radon levels. Methods\ Cases studied including all lung cancer patients diagnosed between Ja nuary 1994 and April 1998,aged 30\|75 years,and resided in two prefectures of Gansu Province.Controls were randomly selected from census lists and matched on age sex and prefecture.Radon detectors were placed in all houses having been occupied two or more years in the past 5\|30 years prior to enrollment.Measurements covered 77% of the possible exposure time. Results\ Mean radon concentrations were 230 4 Bq/m\+3 for the cases( n =768) and 222.2 Bq/m\+3 for the controls( n =1 659).Lung cancer risk increased along with increase of the radon level( P <0.001).Based on a linear model,the excess odds ratio(EOR)at 100 Bq/m\+3 was 0.19(95% CI:0.05,0 47)for all subjects,and 0.31(95%CI:0.10,0.81)for subjects with 100% coverage of the exposure interval.Adjusting for exposure uncertainties increased estimates about 70%. Conclusion\ The results support increased lung cancer risks with indoor radon exposures,which may equal to or exceed extrapolation\|based risks from miner data.

目的 直接调查居室水平氡浓度对居民肺癌危险度的影响 ,并与由矿工受照结果推导的结论相比较。方法 在甘肃省平凉、庆阳两地区进行病例 对照研究。该地区居民稳定而室内氡水平较高。肺癌病例必须是在 1994年 1月至 1998年 4月期间诊断 ,年龄在 30~ 75岁之间 ,居住在平凉和庆阳两地区的居民。根据人口调查资料随机选取对照 ,对照要在年龄、性别、地区方面与病例相匹配。在过去 5~ 30年期间 ,凡住过两年以上的房间都布放了氡探测器。氡测量涵盖了 77%的照射周期。结果 病例居室的平均氡浓度为 2 30 4Bq m3 (n =76 8) ,对照为 2 2 2 2Bq m3 (n =16 5 9)。居民肺癌危险度随室内氡水平的增高有所上升 (P <0 0 0 1)。根据线性模型 ,对全部研究个体而言 ,在 10 0Bq m3 情况下 ,附加比值比 (EOR)为 0 19(95 %CI:0 0 5 ,0 47)。对测量涵盖了 10 0 %照射周期的个体 ,为 0 31(95 %CI:0 10 ,0 81)。在对照射的不确定度进行调整后 ,估算值可增加70 %。结论 研究结果证明室内水平氡照射会...

Objective To investigate effect of cooking oil fumes to lung cancer risk of Chinese women. Method A population - based case - control study in Gansu Province is conducted for investigating the association between lung cancer and locally made rapeseed and linseed oils. Two hundred thirty - three incident, female lung cancer cases diagnosed from 1994 - 1998 were identified.

Objective To investigate effect of cooking oil fumes to lung cancer risk of Chinese women. Method A population - based case - control study in Gansu Province is conducted for investigating the association between lung cancer and locally made rapeseed and linseed oils. Two hundred thirty - three incident, female lung cancer cases diagnosed from 1994 - 1998 were identified. A control group of 459 women was selected from census lists and were frequency matched on age and prefecture. Interviewers obtained information on cooking practices and cooking oil use. Result The odds ratio (OR) for lung cancer associated with ever - use of rapeseed oil, alone or in combination with linseed oil, was 1.67 (95% CI 1.0 - 2.5) , compared to use of linseed oil alone. ORs for stir- frying with either linseed or rapeseed oil 15 - 29, 30 and≥31 times per month were 1.96, 1.73, and 2.24, respectively (trend, P = 0.03) , relative to a lower frequency of stir - frying. Conclusion Women exposed to cooking fumes from rapeseed oil appeared to be at increased risk of lung cancer, and there was some evidence that linseed oil may have also contributed to the risk. Lung cancer risks also increased with total number of years cooking (trend, P < 0.09) .

目的 研究不同类食用油油烟对妇女肺癌危险度的影响。方法 在甘肃东部进行一项以人群为基础的病例-对照流行病学研究,以对肺癌与当地产菜子油和胡麻油的关系进行调查。在1994~1998年期间诊断出妇女肺癌233例。根据人口调查资料随机选出459名妇女作为对照,对照在年龄和地区方面与病例频数匹配。调查中获得了做饭情况和食用油使用方面的资料。结果 单独使用菜子油、混用莱子油和胡麻油与单独用胡麻油相比,肺癌比值比(OR)为1.67(95% CI 1.0~2.5)。与炒菜次数少的相比,每月用胡麻油或菜子油炒菜15~29次,30次和30次以上时,其OR值分别为1.96,1.73和2.24(趋势检验,P<0.03)。结论 妇女受来自菜子油的油烟暴露,会使肺癌危险度增加,胡麻油也可能有部分贡献。肺癌危险度也随做饭年数的增加而升高(趋势检验,P
