Abstract
Epidemiology is the study of the occurrence of disease in populations. It originates from an observational discipline that describes changes in the prevalence or incidence of a specific disease — changes that may be observed over time, between geographical regions, or between populations. Thus, basic epidemiology delivers numbers with no explanation. Prevalences or incidences are, however, only really useful if associated with explanatory variables. These variables may relate to genetics, lifestyle, age, gender, occupation, environment, etc. Environmental epidemiology is therefore the study of associations between environmental exposures and the occurrence of disease within a population.
