Chapter 1 - History And Scope Of Epidemiology Flashcards
Biostatistics
A field of statistics that is applied to living organisms
Chronic disease
A long lasting illness that is difficult to eradicate
Communicable Disease
An illness cause by an infectious agent that can be transmitted from one person to another
Demography
The study of data (e.g., births, deaths, and socioeconomic status) related to the structure of human populations.
Distribution
Differential frequency in the occurrence of disease and mortality among population groups (or among sub-groups of a population)
Endemic
A disease or infectious agent that is habitually present in a community, geographic area, or population group. Often an endemic disease maintains a low but continuous incidence.
Epidemic
Occurrence of a disease in excess of normal expectancy.
Epidemiology
Study of the distribution and determinants of health and disease, morbidity, injuries, disability, and mortality in populations. Epidemiologic studies are applied to the control of health problems in populations.
Genetic epidemiology
Field of epidemiology concerned with inherited factors that influence risk of disease
Levels
Denotes the hierarchy of tasks that epidemiology studies seek to accomplish.
Lifestyles
Habits, behaviors (smoking, drinking, and exercise levels), or dietary practices that influence health.
Molecular epidemiology
Field of epidemiology that uses bio markets to establish exposure-disease associations. Examples of biomarkers are serum levels of micronutrients and DNA fingerprints.
Morbidity
Occurrence of an illness or illnesses in a population
Mortality
Occurrence of death in a population
Natural Experiment
A type of research design in which the experimenter does not control the manipulation of a study factor(s). The manipulation of the study factor occurs as a result of natural phenomena or policies that impact health, an example being laws that control smoking in public places.
