Epidemiology

Epidemiology has been defined as the study of the distribution and determinants of health related states or events in human populations, and the application of this study to the prevention and control of health problems. Thus, epidemiologists are concerned not only with studying health, disease and death but also with devising means to prevent illness and improve health." Ray M. Merrill, Introduction To Epidemiology.

Occupational Epidemiology involves the application of epidemiologic methods to populations of workers. Occupational epidemiologic studies may involve looking at workers exposed to a variety of chemical, biological or physical (e.g. noise, heat, radiation) agents to determine if the exposures result in the risk of adverse health outcomes. Alternatively, epidemiologic studies may involve the evaluation of workers with a common adverse health outcome to determine if an agent or set of agents may explain their disease. (OSHA)
