Mortality analyses for rungsten miners]

OBJECTIVE: To investigate the mortality from main causes of death in 6 tungsten miners and explore the effects of cumulative dust exposure on standardized mortality ratios (SMRs) from main causes. METHODS: A cohort of 18027 workers registered in the employment record from 6 tungsten mines located in Hunan and Jiangxi province and working for at least 1 year was identified for this study. SMRs were calculated based on Chinese national mortality. Trend analysis was used to analyze the effect of cumulative dust exposure on SMRs of main causes of death. RESULTS: The cohort was followed up from 1972 to 2003 with an accumulative of 470 722.21 person-years. A total of 6135 workers died, and the mortality was 13.03 per thousand. Cardiovascular disease, respiratory disease, malignant neoplasm and pulmonary tuberculosis accounted for 79.32% of all death. The mortalities of all-causes, pneumoconiosis, pulmonary tuberculosis, nasopharyngeal carcinoma, infectious disease, respiratory disease, cardiovascular disease and liver cancer were found to be significantly higher than the national average level. Positive dose-response relationship between SMRs and cumulative dust exposure was observed in all-causes, pneumoconiosis, pulmonary tuberculosis, respiratory disease, cardiovascular disease (P < 0.01). CONCLUSION: The mortality from main causes of death for the dust-exposed workers are higher than that for non dust-exposed workers. Positive dose-response relationships are observed between cumulative dust exposure and SMRs from all-causes, respiratory disease (including silicosis), pulmonary tuberculosis and cardiovascular disease.

Mortality in miners and millers of crocidolite in Western Australia.

It is known that 6505 men and 411 women were employed in the mining and milling of crocidolite at Wittenoom in the Pilbara region of Western Australia between 1943 and 1966. Employment was usually brief (median duration four months) and exposure intense (median estimated cumulative exposure 6 fibres/cc years). The vital status of 73% of the men and 58% of the women employed in the industry was known at 31 December 1980, providing 95 264 person-years of follow up with 820 deaths in men and 4914 person-years with 23 deaths in women. The standardised mortality ratio (SMR) for all causes in men was 1.53 (95% confidence interval 1.43 to 1.64). Statistically significant excess death rates were observed in men for neoplasms, particularly malignant mesothelioma (32 deaths), neoplasms of the trachea, bronchus, and lung (SMR 2.64), and neoplasms of the stomach (SMR 1.90); respiratory diseases, particularly pneumoconiosis (SMR 25.5); infections, particularly tuberculosis (SMR 4.09); mental disorders particularly alcoholism (SMR 4.87); digestive diseases, particularly peptic ulceration (SMR 2.46) and cirrhosis of the liver (SMR 3.94); and injuries and poisonings, particularly non-transport accidents (SMR 2.36). The excess mortality from pneumoconiosis, malignant mesothelioma, and respiratory cancers, but not stomach neoplasms, was dependent on time since first exposure and cumulative exposure. There was no increase in mortality from laryngeal cancer (SMR 1.09) or neoplasms other than those listed. The SMR for all causes in women was 1.47 (95% confidence interval 0.98-2.21) and for neoplasms 1.99; there was one death from malignant pleural mesothelioma.

Mortality among North Carolina construction workers, 1988-1994

This study evaluated proportionate mortality patterns among all male construction workers in North Carolina who resided and died in North Carolina during the period 1988-1994. Proportionate Mortality Ratios (PMRs) and Proportionate Cancer Mortality Ratios (PCMRs) compared the number of deaths among male construction workers with the number of deaths expected based on the gender, race, and cause-specific mortality experience of the entire North Carolina population by five-year age groups for the same years of study. PMRs based on United States death rates also were calculated. Among all male construction workers, significantly elevated mortality was observed for several causes possibly related to work including malignant neoplasms of buccal cavity (PMR = 143), pharynx (PMR = 134), and lung (PMR = 113), pneumoconiosis (PMR = 111), transportation accidents (PMR = 106), and accidental falls (PMR = 132). Elevated mortality also was observed for causes more related to lifestyle and non-occupational factors including alcoholism (PMR = 145), cirrhosis of the liver (PMR = 129), accidental poisoning (PMR = 136), and homicide (PMR = 141). Patterns of elevated mortality for Whites and Black men were similar and PCMR mortality patterns for Blacks and Whites combined were similar to PMRs. Construction workers were at significantly increased risk for deaths resulting from falls from ladders or scaffolds, falls from or out of buildings or structures, and electrocutions. Construction trades found to have statistically elevated cancer risks include laborers and roofers (buccal cavity), painters (pharynx), laborers (peritoneum), and carpenters, painters, brick masons, and operating engineers (lung). These data are consistent with other reports demonstrating excess mortality from asbestos-related diseases (pneumoconiosis, lung cancer, and mesothelioma) among construction workers. Dry-wall workers and laborers were found to have a statistically elevated risk of death as a result of respiratory tuberculosis.     

Changing patterns of pneumoconiosis mortality--United States, 1968-2000

Pneumoconioses are caused by the inhalation and deposition of mineral dusts in the lungs, resulting in pulmonary fibrosis and other parenchymal changes. Many persons with early pneumoconiosis are asymptomatic, but advanced disease often is accompanied by disability and premature death. Known pneumoconioses include coal workers' pneumoconiosis (CWP), silicosis, asbestosis, mixed dust pneumoconiosis, graphitosis, and talcosis. No effective treatment for these diseases is available. This report describes the temporal patterns of pneumoconiosis mortality during 1968-2000, which indicates an overall decrease in pneumoconiosis mortality. However, asbestosis increased steadily and is now the most frequently recorded pneumoconiosis on death certificates. Increased awareness of this trend is needed among health-care providers, employers, workers, and public health agencies.     

Time trends in mortality in forestry and construction workers in Finland 1970-85 and impact of adjustment for socioeconomic variables.

STUDY OBJECTIVE--This study aimed firstly to describe the development of cause-specific mortality in forestry workers, farmer/forestry workers, and skilled and semiskilled construction workers between 1970 and 1985 in Finland, and to compare this with mortality in the total working male population. The second aim was to evaluate how well the cause-specific mortality differences between the occupations could be explained by differences in socioeconomic status, marital status, or in the region of residence. DESIGN AND SETTING--This is a follow up study based on the 1970, 1975, and 1980 census records in Finland linked with all death certificates for 1971-75, 1976-80, and 1981-85 respectively. Log-linear regression analysis was used. SUBJECTS--All economically active men in Finland aged between 35 and 64 years in 1971-85 were studied. The number of person-years in the period totals about 10 million. MAIN RESULTS--Semiskilled construction workers had the highest mortality rate almost independent of the cause of death. The mortality of forestry workers was the second highest. Compared with the reference population, however, the differences were small with regard to neoplasms and cardiovascular diseases. With regard to other diseases, only the mortality of semiskilled workers was fairly high. Differences in mortality as a result of accidents were the highest. Both suicide and accidental death rates were high in semi-skilled construction workers and forestry workers. During the study total mortality fell by about 30% but mortality differences between groups did not decline. CONCLUSIONS--The high mortality of forestry and semiskilled construction workers is partly explained by socioeconomic factors such as marital status and housing conditions. These factors do not, however, explain the high suicide and accident mortality rates of forestry workers or semiskilled construction workers. More research is needed to explain these findings.

Analysis of mortality patterns in an area supplying tunnel workers away from home. Part 2. Mortality patterns among tunnel workers

In order to clarify the long-term effect of tunnel work on the health of its workers, we examined its cause-specific mortality pattern. The subjects were 418 males who died after the age of 30 in 1977 in the southern part of Oita Prefecture, where many men come and work away from home as tunnel workers. Death certificates, 418 in number, presented to the health center were used to examine the causes of death. Occupational careers and life histories of the subjects were obtained by interviewing their families or relatives in 1980. The interviews were successfully carried out with 356 subjects (85.2%). The subjects were divided into two groups. One group was consisted of 73 males who had engaged in the tunnel work (tunnel workers) and the other was of 283 males without experience of tunnel work (others). Proportional mortality ratio (PMR) and proportional mortality classified by age were compared between the two groups. The mean ages at death were also compared among these two groups and all Japanese males over 30 years of age. The results were as follows. The proportion of the deaths of "tunnel workers" among the total deaths in the area surveyed was correlated to the regional rate of tunnel workers and the distribution of pneumoconiosis due to tunnel work. These results show that many tunnel workers suffering from pneumoconiosis had returned to their home area before they died. Excess deaths from the ICD category I; infective and parasitic diseases (000-136), tuberculosis (010-019) and silicotuberculosis (010) were found among the "tunnel workers."(ABSTRACT TRUNCATED AT 250 WORDS)     

Retrospective mortality cohort study of Italian workers compensated for silicosis

Objectives

To estimate cause specific mortality in a large cohort of Italian workers compensated for silicosis.

Methods

The cohort included 14 929 subjects (14 098 men and 831 women) compensated for silicosis between 1946 and 1979, alive on 1 January 1980, and resident in Tuscany (a region of central Italy with 3 547 000 inhabitants). Mortality follow up ranged from 1980 to 1999. Vital status and the causes of death were determined by linkage with the regional mortality registry and with the national mortality database. The cohort mortality rates were compared to the rates of the local reference population. SMRs and their 95% confidence intervals were computed assuming a Poisson distribution of the observed deaths. Specific SMR analyses were performed according to the level of disability, the year of compensation assignment, and the job type.

Results

A significant excess mortality was observed in male silicotics for cancer of the lung, trachea, and bronchus and cancer of the liver, respiratory diseases (silicosis, asbestosis, antracosilicosis, and other pneumoconiosis), and for tubercolosis. Statistically significant mortality excess was observed in female silicotics for respiratory diseases (specifically silicosis and other pneumoconiosis) and tuberculosis. Analyses for period of compensation assignment showed a twofold increased SMR for biliary tract cancer among female workers and for liver cancer among male workers compensated before 1970.

Conclusions

The excess mortality from respiratory tract cancers and respiratory tract diseases detected in Italian compensated silicotics are in agreement with previous epidemiological studies. Although the twofold increased risk for liver cancer among males is suggestive of a possible association with silica dust exposure, the finding needs to be confirmed.
