Calculations Flashcards
Crude birth rate
Preterm births rate
Low birth weight rate
General fertility rate (GFR)
Age-specific fertility rate
Total fertility rate (TFR)
- Age-specific fertility rate calculation
- Fertility rate x 5 = N of children/woman in 5 years
- Average of the number of children a woman would bear during her productive lifetime (15-49) in 5 years
TFR > 2 means growing population
TFR < 2 means decreasing population
Crude death (mortality) rate
Age and sex related mortality rate
General infant mortality rate
NOT A GOOD MEASUREMENT AS A BABY MAY DIE THE YEAR AFTER EVEN IG IT’S WITHIN THE 365 DAYS
Perinatal infant mortality rate
Postnatal infant mortality rate
Neonatal infant mortality rate
Post-neonatal infant mortality rate
Fetal death rate
It may be related to the number of live births of the number of fertile female population.
Maternal mortality rate
It represents the death cases of women who die during pregnancy and childbirth including the first 42 days after the delivery.
Population growth
Comparative mortality ratio (CMR)
(=Relative mortality risk)
Standardized mortality rate of diseased population/standardized mortality rate of healthy population
Standardized mortality ratio (SMR)
For indirect standardization
Standardized mortality rate
(Observed deaths/Expected deaths) x 1000
For direct standardization
Defining risk (formulas)
Incidence
Prevalence
Validity measurements of screening tests (sensitivity and specificity)
Predictive value of screening tests (PPV and NPV)
Measure of risk in case-control study
Ageing index
Old age dependency ratio
