How is epidemiology used in environmental health?

Environmental epidemiology is one of the most important tools used in environmental management decision making owing to its capacity to assess and monitor environmental hazards in different settings and quantify their health impact on the population at risk.

How does epidemiology relate to environmental health?

Epidemiologists study the factors that cause disease and the distribution of diseases within the population. Environmental epidemiology focuses on the ways environmental factors (physical, chemical and biological) affect the health of populations.

What are some of the key uses of epidemiology in environmental health?

How is the epidemiological approach used to study health problems related to the environment?

Environmental epidemiology is the study of the distribution and environmental determinants of disease. This observational science relies upon events occurring within human populations, so-called natural experiments, from which inference is drawn to identify causes of disease.

Where do environmental epidemiologists work?

What is environmental and occupational epidemiology?

Occupational and environmental epidemiology are two sub-disciplines of epidemiology that focus on studying the potential health risks of exposures to chemicals, particulates, metals, physical factors, infectious disease agents, and psychosocial factors in the workplace and general environment.

What are the epidemiological approaches?

What epidemiology means?

By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).

What is exposure science in environmental health?

Exposure science is the study of an organism’s (usually human) contact with chemical, physical, biological agents or other health risk (e.g. accidental) occurring in their environments, and advances knowledge of the mechanisms and dynamics of events either causing or preventing adverse health outcomes.

Why epidemiology sometimes is called population medicine?

Epidemiology is sometimes called population medicine. The occurrence of diseases and other health outcomes varies in populations, with some subgroups of the populations more frequently affected than others.
