Cumulative trauma disorders of the hand and wrist in the auto industry.

Surveillance for cumulative trauma disorders (CTDs) of the hand and wrist was carried out in five US automotive plants from 1985 to 1986, using Occupational Safety and Health Administration (OSHA) Form 200 injury and illness logs and medical insurance claims. Results using both record sources indicated that hand and wrist disorders may be more common in foundries than in other types of automotive plants. Similarly, in assembly plants, employees in certain departments appeared to be at higher risk for CTDs. Although our results are based on small numbers of cases, they suggest plants and departments that might be targeted for more detailed investigation.

Use of medical insurance claims for surveillance of occupational disease. An analysis of cumulative trauma in the auto industry.

Medical insurance claims, linked with work histories for a large automotive manufacturer over a 3-year period, identified large numbers of cases of potentially work-related diseases, including 30,600 episodes of probable cumulative trauma disorders (CTD). CTD incidence rates were calculated within five plants, and high-risk areas identified, however, unknown differences in medical insurance coverage by exposure group limited interpretation. Case-control analyses, with controls also identified by insurance claims, addressed coverage and produced age-adjusted and sex-adjusted estimates of risks. All five plants had departments with statistically significant, elevated risks for one or more of the diagnoses carpal tunnel syndrome, CTD of other upper extremities, rotator cuff syndrome, CTD of the neck and of the lower back. Medical insurance claim data linked with work history provide the basis for practical and comprehensive surveillance for CTD and potentially a variety of other occupational diseases.

Brain cancer mortality at a manufacturer of aerospace electromechanical systems.

Standardized proportional mortality ratios and mortality odds ratios were calculated for 583 deaths between 1950 and 1986 among employees who had worked for at least 10 years at a facility manufacturing missile and aircraft guidance systems. There was a statistically significant excess of brain cancer proportional mortality (PMR = 16/3.8 = 4.2, p = .0001). Among hourly employees, 12 brain cancer deaths occurred for 2.7 expected (PMR = 4.4, p = .00005). The PMR for brain cancer increased from 1.8 (p = .45) among hourly workers with less than 20 years to 8.7 (p = .000003) in those with more than 20 years employment. Work in "clean rooms," where gyroscopes were assembled, was associated with the brain cancer excess but did not fully account for it. Among 105 deceased hourly women, all three brain cancer deaths occurred among gyro assemblers working in clean rooms, and the risk increased with duration in clean rooms. Although the proportion of brain cancer deaths among hourly men with clean-room experience was similar to that for women, only three of the seven male brain cancer deaths occurred in this group. The suspect agents include gyro fluids and chlorofluorocarbon solvents.

Causes of death among workers in a bearing manufacturing plant.

Recent studies identify digestive cancer excesses among workers exposed to cutting fluids, abrasive dusts, and oil smoke. Standardized proportional mortality and mortality odds ratio studies were carried out for a ball bearing plant. Cause of death and work histories were obtained for 702 of 768 hourly employees with ten or more years' service who died between 1969 and 1982. Union and company records were used to define exposure measures. The major findings were significant excesses in proportional mortality ratios (PMR) from stomach cancer (PMR = 2.0) and rectal cancer (PMR = 3.1) among white men. After control for age at death, there was a significant association between stomach cancer and precision grinding exposures, consisting primarily of direct contact with water-based cutting fluids (usually emulsified oils) and their aerosols. Some straight oils and synthetic cutting fluids were used as well. The pattern of stomach cancer is consistent with previous findings and suggests an association with the soluble oil cutting fluids.

Occupational cancer in metalworking and transportation equipment industries.

Hazardous chemical exposures may be a more important public health problem in chemical-using industries, such as the metalworking and transportation equipment industries, than in chemical manufacturing plants. Recent studies have identified excess mortality from cancer among groups of workers in model and patternmaking, plating and die-cast, foundry, machining, electronics operations and vehicle assembly plants. The chemical agents or levels of exposure associated with these findings have not previously been thought to pose a cancer risk. Therefore, estimates of the fraction of cancers associated with workplace exposure may understate the importance of exposure in this setting.
