| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
|---|---|
| journal article | The predominant publication type for articles and other items indexed for nlm databases. (12 Dec 1998) |
| environmental pollutants, noxae, and pesticides | Substances capable of producing a harmful or deadly effect on living organisms as well as the environment. (12 Dec 1998) |
| classical epidemiology | <epidemiology> Our term for the varieties of epidemiology primarily concerned with the statistical relationships between disease agents, both infectious and non-infectious; for example a study to establish the relative risk of lung cancer associated with smoking. We contrast this with ecological epidemiology. (05 Dec 1998) |
| clinical epidemiology | The field concerned with applying epidemiological principles in a clinical setting.Whereas classical epidemiology studies populations in an attempt to assess causes and distribution of disease and to formulate statistical measures of risk, clinical epidemiology focuses on medically defined populations (patients). (05 Mar 2000) |
| ecological epidemiology | <epidemiology> A branch of epidemiology which views disease as a result of the ecological interactions between populations of hosts and parasites; what we do. We contrast this with classical epidemiology. (05 Dec 1998) |
| epidemiology | <study> The study of the distribution and determinants of health-related states and events in populations and the control of health problems, the study of epidemic disease. (27 Sep 1997) |
| epidemiology, classical | The study of populations in order to determine the frequency and distribution of disease and measure risks. (12 Dec 1998) |
| epidemiology, clinical | Epidemiology focused specifically upon patients. (12 Dec 1998) |
| epidemiology, molecular | The application of molecular biology to the answering of epidemiological questions. The examination of patterns of changes in DNA to implicate particular carcinogens and the use of molecular markers to predict which individuals are at highest risk for a disease are common examples. (12 Dec 1998) |
| costs and cost analysis | Absolute, comparative, or differential costs pertaining to services, institutions, resources, etc., or the analysis and study of these costs. (12 Dec 1998) |
| task performance and analysis | The detailed examination of observable activity or behaviour associated with the execution or completion of a required function or unit of work. (12 Dec 1998) |
| maternal exposure | Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure. (12 Dec 1998) |
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| paternal exposure | Exposure of the male parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. (12 Dec 1998) |
