What are the characteristics of environmental epidemiology?

To make a reasonable inference of causation in environmental epidemiology, eight basic characteristics of the findings should be considered: the strength, specificity, and consistency of the association; the period of exposure; the biologic gradient or the relationship between the dose and the response; the effects of …

What are the characteristics of epidemiology?

Epidemiology is the study (scientific, systematic, data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (patient is community, individuals viewed collectively), and the application of (since …

What is the basis for environmental epidemiology?

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.

Why is environmental epidemiology important?

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.

What are the characteristics of environmental health?

Environmental health refers to aspects of human health (including quality of life) that are determined by physical, chemical, biological, social and psychosocial factors in the environment.

What are the three characteristics of epidemiology?

Descriptive epidemiology searches for patterns by examining characteristics of person, place, & time . These characteristics are carefully considered when a disease outbreak occurs, because they provide important clues regarding the source of the outbreak.

What are the key 6 characteristics of epidemiology?

It extracts six types of epidemiological characteristic: design of the study, population that has been studied, exposure, outcome, covariates and effect size.

What is environment and environmental pollution?

Environmental pollution is defined as “the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected. From: Environmental Management, 2017.

Where do environmental epidemiologists work?

Epidemiologists are public health workers who investigate patterns and causes of disease and injury. Epidemiologists work in offices and laboratories, usually at health departments for state and local governments, in hospitals, and at colleges and universities.

What are environmental contaminants?

Environmental contaminants are chemicals that accidentally or deliberately enter the environment, often, but not always, as a result of human activities. Some of these contaminants may have been manufactured for industrial use and because they are very stable, they do not break down easily.

What are the benefits to health when environmental epidemiology strategies are used?

It can also contribute to chronic disease epidemiology the better identification and measurement of independent variables when these are environmental exposures and conditions. Environmental epidemiology has the advantage of being able to study and possibly prevent health impairment which has not yet led to disease.

Why is epidemiology important to the study of environmental health problems?

Epidemiology is important to the study of environmen- tal health problems because (1) many exposures and health effects associated with the environment occur at the popula- tion level; (2) the epidemiologic methods of natural experi- ments and observational techniques are appropriate; (3) the study designs used in …

What is the epidemiological triangle?

The Epidemiologic Triangle, sometimes referred to as the Epidemiologic Triad, is a tool that scientists use for addressing the three components that contribute to the spread of disease: an external agent, a susceptible host and an environment that brings the agent and host together.
