卷烟厂男性职工恶性肿瘤死亡回顾性队列研究   总被引:1,自引:0,他引:1  
为分析烟草尘对卷烟厂男性职工恶性肿瘤死亡专率的影响,采用回顾性队列研究的方法,对河南、黑龙江两省某两卷烟厂1982~1994年间在册的男性职工进行恶性肿瘤死因分析。以队列成员中的非暴露于烟草尘组为内对照,比较两组间的恶性肿瘤死亡专率的差异。结果表明男性职工暴露组的恶性肿瘤死亡专率显著高于非暴露组,且可能存在剂量-效应关系。提示接触烟草尘可能是恶性肿瘤死亡的危险因素,且吸烟和接触烟草尘对上述疾病可能存在协同作用。  相似文献

在皮毛加工业中存在某些职业性危害因素,可能损害职工的身体健康。如职业性炭疽,皮毛工尘肺,非特异性肺部疾病以及动物皮屑变态反应等。此外还有肿瘤高发的报导。天津市于1980年经对159家工厂企业的初步调查,皮毛行业职工的肿瘤死亡粗率确实高于其他行业。为了验证皮毛行业的肿瘤高发是否与职业因素有联系,对本市皮毛、绒毛、尾毛三家皮毛加工厂进行了职工肿瘤死亡调查。三家工厂的加工过程不尽相同。绒毛加工厂主要是对羊毛、兔毛进行水洗、烘干、梳毛、分选、整理、包装等。尾毛加工主要是对各种尾毛进行水洗、烘干、分选、整理、包装等。以上两厂的加工过程基本不使用任何化学物。而皮毛厂除接触原皮、原毛外,还有鞣皮、染色、裁制等作业,其中使用了多种化学物质。经采用回顾性队列调查,选定1961年1月至1975  相似文献

This retrospective cohort mortality study examined 2,467 workers in lubrication products blending and packaging (B&P) operations at two refineries of Mobil Corporation between January 1, 1945 and December 31, 1978. Ninety-seven percent were male. Compared with U.S. males, there were significantly fewer deaths observed among males due to all causes, external causes, and diseases of the circulatory, respiratory, digestive, and genitourinary systems. Deaths observed from all cancer were fewer than expected, although not statistically significant. No statistically significant excess cause-specific mortality occurred at B&P facilities combined or separately. Nonsignificant increases in mortality were observed for cancers of the stomach, large intestine, prostate, the category of "other lymphatic tissue" cancer, and leukemia and aleukemia. Analyses demonstrated a statistically significant pattern of increasing SMR with employment duration for "other lymphatic tissue" cancer. Within the highest cumulative duration of employment category, the excess was confined to workers after 30 or more years since first employment. Although the interpretation of cancer mortality patterns is limited due to small numbers of deaths, the absence of associations with specific B&P departments is evidence against a causal interpretation.  相似文献

We have studied the mortality between 1950 and 1980 of a cohort of 1,143 workers in an electrochemical plant producing cobalt and sodium. The mortality of the whole cohort is significantly lower than in the French population for all causes of death (SMR = 0.77), and especially for deaths from circulatory system diseases (SMR = 0.59). However, among cobalt production workers, there is a relative over-mortality, especially from lung cancers (SMR = 4.66, 4 cases). The relationship between cobalt production and lung cancer mortality was supported by a case-control study nested in the cohort study. The authenticity of the occupational origin of this risk could not be established due to the low number of cases and because the role of tobacco consumption could not be taken into account. Other studies should be carried out in plants producing or using cobalt.  相似文献

This report presents a mortality study among the 17,344 members of the Construction Workers' Health Insurance Society of Mie Prefecture in Japan. The study period was between 1973 and 1993. During this period, 480 members died. Age-specific mortality rates of Mie Prefecture were used as comparison standards. Significantly elevated standardized mortality ratio (SMR) and proportionate mortality ratio (PMR) were observed for “accidents and adverse effects.” In addition, the PMRs of all cancers and “cancers of trachea, bronchus and lung” were also significantly elevated. The job classifications were reorganized into three groups, according to the frequency of asbestos exposure the workers experienced on the construction sites. The asbestos exposure was based on job classifications among 7,411 workers who had completed a self-administered survey questionnaire. In the frequent-exposure group, the PMR was significantly elevated for all cancers. In the medium-exposure group, the SMRs were significantly elevated for all cancers and “cancer of trachea, bronchus and lung.” The PMR was significantly elevated for “cancer of trachea, bronchus and lung.” In the less-exposure group, the PMR was significantly elevated for “accidents and adverse effects.” This study provided support for the hypothesis that working in the construction industry might be associated with high risks for asbestos-associated cancers and accidental deaths.

The mortality of 461 workers who were employed 10 or more years in a Midwest engine and construction equipment plant was examined, using the method of proportional mortality ratios. Both state and national deaths were used as the standard population. Major exposures in this plant included solvents, cutting oils, and metal fumes and dusts. However, precise exposure data were not available. Among white males, no significant deviations from expected deaths were found. Among black males, significant excess deaths were found for all malignant neoplasms combined, for cancer of the pancreas, and for non-Hodgkin's lymphomas. Proportional cancer mortality ratios produced similar results, although the excess of pancreatic cancer in blacks was only significant among those with 20 or more years of service. Although complete occupational histories were not available, these results may provide hypotheses for future studies of workers in heavy machinery production.  相似文献

A study of pulp and paper mill workers indicated low risks of death from all causes (standardized mortality ratio (SMR) = 0.74) and all cancers (SMR = 0.81) compared with U.S. rates. The leukemia death rate in workers was not higher than the U.S. rate but was higher than the rate in county populations surrounding mills. Workers whose last jobs were in the finishing areas of the mills had an elevated SMR for liver cancer. An internal comparison of occupational characteristics indicated that workers employed in mills using other chemical pulping operations had significantly elevated mortality from all causes, all cancers, heart disease, lymphomas, and brain cancers. Lung cancer mortality was elevated in mills using kraft pulping. The internal comparisons confirmed the association between work in finishing and the risk of liver cancer. This study was designed to investigate whether pulp and paper mill workers have any risks that would indicate the need for studies detailing exposures. Am. J. Ind.

A proportional mortality study of the acting profession   总被引:1,自引:0,他引:1  
Proportional mortality of actors and actresses was studied because cancers of many sites have been linked to hair dyes and cosmetics of which actors have been frequent users. Death records (1950-1978) for 2,618 white male and 838 white female members of Actors Equity and the Screen Actors Guild were compared with the U.S. mortality rats. Among males, significantly elevated proportional mortality ratios (PMR) were found for suicide (1.58), cirrhosis of the liver (1.99), all malignancies (1.15), and cancers of the colon/rectum (1.32), pancreas (1.51), and testes (2.37). Colon/rectum and pancreas cancers were not significantly elevated by proportional cancer mortality. Among females, significantly elevated PMRs were found for suicide (2.02) and lung cancer (2.20). Suicide in either sex was much more common in California than in New York. The elevated lung cancer in females was confined to Equity members. No elevations were found for cancers that have been related to hair dye or cosmetic use--ie, breast, ovary, bladder, leukemia, and lymphomas.  相似文献
