prevalence

number of new cases of a disease or condition that occur in a population during a specified period.

incidence

simple relationship between two quantities

ratios

the relationship between a specific characteristic or event and the total population

proportion

a measure of the frequency of an event, characteristic, or outcome in a population over a specific time period

Rates

a specic type of ration the compare a part as a whole

proportion

AKA incidence proportion

cumulative incidence

MEASURES OF ASSOCIATION

RELATIVE RATIO, ODDS RATIO, RISK DIFFERENCE, ATTRIBUTABLE RISK PERCENT, HAZARD RATIO

relative risk ratio is primarily used in what study?

cohort studies

odds ratio is primarily used in what study?

case control studies

AKA the risk ratio

relative risk

compare the risk of an outcome, susch as disease or a condition, between two groups

relative risk

compare the odds of an outcome occurring in one group versus another

odds ratio

AKA absolute risk reduction

risk difference

compare the risk of a certain event or outcome

risk difference

AKA risk attributable percent

attributable risk percent

determine the proportion of the incidence of a disease in the exposed group due to the exposure

attributable risk percent

used in survival analysis

hazard ratio

compare hazard rates

hazard ratio

a very common and important activity in public health departments

epidemiology

descriptive study types

case reports, case series, ecological studies, cross sectional or prevalence surveys

observational study types

case control, cohort , ecological, cross sectional or prevalence survey

experimental study

clinical trial, preventive teial, community intervention trials

study of distribution of disease, health condition, or events in a population

desceiptive epidemiology

provides a comprehensive understanding of the patterns and trends of health events in terms of person time and place

descriptive epidemiology

type of analytic studies

experimental studies, observational studies

a study follows a group of individual OVER TIME, tracking ther exposure to certain factors

cohort study

collected from participants at a SINGLE POINT IN TIME

cross sectional study

a study that identify a group of individuals with a specific outcome and a group without the outcome

case control study

examines the relationship between exposures and outcomes at the population level rather that the individual level

ecological study

looks at persons with a disease or condition and a suitable control group of persons without the condition of interest, and comparing how frequently a suspected attribute or risk factor is present in each group

case control study

flactuations around a true value

random error

occurs when there is a difference betweer the true value

systematic error

occurs when the study subjects are selected

selection bias

arrising from a systematic error

information bias

usually present in a community

endemic

occurs infrequently and irregularly

sporadic

the constant presentor usual prevalence on a disease in a population within a geographic area

endemic

high levels of disease occurence

hyperendemic

an increase and sudden offenabove what is normally expected in that population

epidemic

same definition of epidemic but is often used for more limited geographic area

outbreak

aggregation of cases grouped in place and time

cluster

epidemic that spread over several countries

pandemic
