Confounding in air pollution epidemiology: when does two-stage regression identify the problem?
A two-stage approach has recently been proposed to assess confounding by copollutants or other variables in time-series epidemiology studies for airborne particulate matter (PM), using independent series from different cities. In the first stage of the proposed method, two regression models are fitted for each city in the analysis. The first relates the health effect to the putative causal vari...
متن کاملConfounding and exposure measurement error in air pollution epidemiology
Studies in air pollution epidemiology may suffer from some specific forms of confounding and exposure measurement error. This contribution discusses these, mostly in the framework of cohort studies. Evaluation of potential confounding is critical in studies of the health effects of air pollution. The association between long-term exposure to ambient air pollution and mortality has been investig...
متن کاملA simulation study of confounding in generalized linear models for air pollution epidemiology.
Confounding between the model covariates and causal variables (which may or may not be included as model covariates) is a well-known problem in regression models used in air pollution epidemiology. This problem is usually acknowledged but hardly ever investigated, especially in the context of generalized linear models. Using synthetic data sets, the present study shows how model overfit, underf...
متن کاملCritical issues in air pollution epidemiology.
The epidemiological studies which have had significant impact on the setting of National Ambient Air Quality Standards (NAAQSs) were performed more than twenty years ago. Most of the more recent studies have been seriously flawed in their design and/or execution because they neglected to account for important variables such as: pollutant exposures other than those from ambient air; the influenc...
متن کاملCase-crossover design in air pollution epidemiology.
The case-crossover design was developed to study the effects of transient, short-term exposures on the risk of acute events, such as myocardial infarction, in the early 1990s. This paper illustrates how the principles of case-crossover design are related to the principles of crossover and case-control designs and stipulates the possibilities of case-crossover design in air pollution epidemiolog...
