HOMEWORK ASSIGNMENT 1
Researchers can quantify the occurrence of disease by making use of measures of disease frequency (MODF),
such as
● Prevalence (and variants of this MODF: point, period, and lifetime prevalence);
● Incidence (and variants of this MODF: cumulative incidence and incidence density);
● Mortality;
● Case fatality rate (CFR)
1a. Define all these MODF. How should one calculate these measures?
Prevalentie: het aantal mensen met een bepaalde ziekte in de populatie
Punt prevalentie: deel (proportie of percentage) van de populatie waarbij een bepaalde gezondheidstoestand
op een bepaald tijdstip aanwezig is.
- Formule: aantal ziektegevallen op een bepaald moment/ totale populatie op dat moment
Periode prevalentie: deel van de populatie dat de ziekte heeft gehad in een bepaalde periode
- Formule: totaal aantal zieken in een bepaalde periode/ gemiddelde van de totale populatie aan het
begin en einde van de periode (Nstart + Neind / 2)
Lifetime prevalentie: deel van de populatie dat tot een bepaald moment een bepaalde ziekte heeft gehad
- Formule: aantal ziektegevallen tot een bepaald moment/ totale populatie in de periode
*Dynamische populatie → eerst het gemiddelde aantal personen in de populatie in de periode uitrekenen.
Incidentie: deel van de populatie (populatie at risk) waarbij een ziekte in een bepaalde periode voor het eerst
optreedt
Cumulatieve incidentie: deel van de populatie dat gedurende een periode de ziekte krijgt
- Formule: totale aantal nieuwe zieken in een bepaalde periode/ totaal aantal personen at risk in de
populatie aan het begin van deze periode
