Question Answer
morbidity disease rate
mortality death rate
incidencenew cases/population at risk or person years
prevalencetotal cases new and existing/population at midpoint of a year not a rate and can not be used for etiology only burden of disease
Cumulative incidencenew cases/at risk
incidence densitynew cases/person years (time period) can tell cause or etiology of disease
Attack rateincidence rate for rare diseases with a short period of time
Fixed populationpermanent membership to the population
Open/dynamic populationmembership by location or condition as state
steady state populationleaving population is the same as the incoming population as an undergraduate class
Countnumber of cases of a disease or phenomenon usually a rare and fatal disease
proportiona count that is descriptive to a group and relative to its size addressing the magnitude of a problem
ratiorelative relationship comparing two groups that are mutually exclusive
ratefrequency of disease over time
memorize

section 2

Question Answer
crude ratesdisease or health event frequency unit of a certain population
crude birth rate# total live births/total population size at the time
crude mortality rate#deaths/population size at the time
general fertility rate#live births for that year/# of women in population between the ages of 15-44
infant mortality rate# infant deaths (those that are between 0-365 days old)/ total live births that year
neonatal mortality rate# infant deaths of those ages 0-28 days old/total # live births
postnatal mortality rate#infant deaths of those aged 28-365 days old/total live births - neonatal deaths (0-28 days old)
fetal death rate# deaths of those 20+ weeks gestation/#live births in the year + # fetal deaths (20+ weeks)
late fetal death rate# deaths of those 28+ weeks gestation/# live births + late fetal deaths (28+ weeks)
perinatal mortality rate# deaths of those 28wks+ in a year + infant deaths within 7 days of birth/#live births + #late fetal deaths
maternal mortality rate# maternal deaths due to child birth/#live births in a year
memorize

section 3

Question Answer
Gestation20-37 wks, time spent inside the mother
fetal period20+ weeks gestation
late fetal period28+ weeks gestation
perinatal period28 weeks gestation to 7 days after birth
neonatal periodbirth aka 0 to 28 days alive
infant periodbirth to 365 days old
postnatal period28 days after birth - 365 days old
prematurebefore 37 weeks gestation
memorize

section 4

Question Answer
specific ratespertain to a specific age group, COD, socioeconomic status, gender etc
age specific mortality rate#deaths of certain age group/total number of those in the age group
Cause specific mortality# of deaths from specific cause/total population at midpoint
Proportion mortality ratioPMR, shows at midpoint the rate of dying from one cause relative to other causes #deaths from specific cause/# of deaths from all causes in population at midpoint
Direct Standardized mortality ratioDSMR tells the mortality experience of two populations when adjusting them, if the amount comes up to more than 100% this means that the test population had a higher mortality experience than the standard population adjusted rate of test pop/CMR of standard population X100
Standard mortality rateobserved deaths/expected deaths X100
standard populationusually from the 2000 US census, the population used to adjust the test population
test populationthe population that is adjusted
Premature mortality rateapplies to those age 75 and under per 100000 people, covers all of the deaths that could have been avoided
SEERdisease registry for cancer incidence, mortality, and trends
BRFSSBehavioral Risk factor surveillance survey, phone survey in US to analyze risk collecting data about behaviors, chronic conditions, and use of preventative services
Youth Health SurveyYHS, run by state departments of public health in MA, tests high and middle schoolers about behaviors relating to health, questions may be skipped
Youth Risk Behavior Studyrun by the CDC and department of elementary and secondary schooling, only given to high schoolers both CDC and state questions asked
