Epidemiology - answer the study of what falls upon the people
epidemiology classical definition - answer study of the distribution and determinants of
disease frequency in human populations
newer definition - answer study of the distribution and determinants of health-related
states or events in specified populations and the application of this study to control of
health problems
key characteristics of epidemiology - answer-distribution
-determinants & exposures
-outcomes
-quantification
-population focus
-control of health problems
distribution - answerhow the occurrence of diseases and other health outcomes varies
in populations
-with some subgroups of the populations more frequently affected than other subgroups
determinants - answerany factor that brings about change in a health condition or other
defined characteristic
examples: biologic agents, environmental exposures, cigarettes
exposures - answercontact with a disease-causing factor
amount of the factor that impinges upon a group or individuals
outcomes - answerall the possible results that may stem from exposure to a causal
factor
outcomes are expressed as types and measures of - answermorbidity (illness) and
mortality (death)
quantification - answercounting cases of illnesses or other health outcomes
quantification denotes the use of statistics to - answerdescribe the occurrence of health
outcomes and measure their association with exposures
epidemiology is a - answerquantitative discipline
