Overall Mortality and Cancer Mortality of Coal Miners: Attempts to Adjust for Healthy Worker Selection Effects
نویسندگان
چکیده
The presumption of a possibly elevated cancer risk in coalminers is based mainly on two hypotheses. Firstly most coalmine dusts include a relevant quartz dust fraction. With a view to the possibly causal relationship between pure quartz dust exposure/ silicosis and lung cancer excess risk it is of interest to investigate whether there exists an elevated lung cancer risk in coalminers. Secondly a fraction of the inhaled coalmine dust particles is cleared from the lung. It is probable that some of the cleared dust is swallowed, which then interacts with the acidic environment in the stomach and finally may cause an elevated gastric cancer risk in coalminers. To explore whether such elevated cancer risks exist, we organised a mortality follow up study on German hard coal miners.

Does exposure to coal dust prevent or cause lung cancer?
Research published in this journal and elsewhere has demonstrated an increased risk of pneumoconiosis and more recently chronic obstructive pulmonary disease among coal miners. Despite this extensive research base, many puzzles remain such as the deficit of lung cancer reported in many studies of coal miners. These findings are surprising since in addition to coal dust, miners are exposed to ot...
متن کاملCoal dust exposure and mortality from ischemic heart disease among a cohort of U.S. coal miners.
BACKGROUND Particulate exposure from air pollution increases the risk of ischemic heart disease (IHD) mortality. Although coal miners are highly exposed to coal dust particulate, studies of IHD mortality risk among coal miners have had inconsistent results. Previous studies may have been biased by the healthy worker effect. METHODS We examined the dose-response relationship between cumulative...
متن کاملHealthy worker survivor bias in the Colorado Plateau uranium miners cohort.
Cohort mortality studies of underground miners have been used to estimate the number of lung cancer deaths attributable to radon exposure. However, previous studies of the radon-lung cancer association among underground miners may have been subject to healthy worker survivor bias, a type of time-varying confounding by employment status. We examined radon-mortality associations in a study of 4,1...
متن کاملAirway responsiveness and job selection: a study in coal miners and non-mining controls.
BACKGROUND It has been suggested that health related job selection is a major cause of the healthy worker effect, and may result in inaccurate estimates of health risks of exposures in the working environment. Improved understanding of self selection, including the role of airway hyperresponsiveness, should improve accuracy in estimating occupational risks. METHODS We evaluated symptoms of th...
متن کاملMobility of diesel versus non-diesel coal miners: some evidence on the healthy worker effect.
Workers who are particularly susceptible to the effects of their occupational exposure, from the perspective of the healthy worker effect, soon leave the workplace. The result of this mobility, called survival bias, is that cross sectional studies based on the survivors underestimate the true risk of occupational exposures. Two questions are addressed in this empirical study of the "survival bi...
