M1: frequentiematen van ziekte

Opgave 1
a.
CI = (aantal nieuwe ziektegevallen in periode P/ totale populatie at risk) x 100%
Jaar 1:
Aantal nieuwe ziektegevallen: 34
Totale populatie at risk: 120.852
(34/ 120.852) x 100% = 0,0281% per jaar
Jaar 2:
Aantal nieuwe ziektegevallen: 40
Totale populatie at risk: 120.852 -34
(40/ (120.852 - 34)) x 100% = 0,0331% per jaar
Jaar 3:
Aantal nieuwe ziektegevallen: 41
Totale populatie at risk: 120.852 -34 -40
(41/ (120.852 – 34 – 40)) x 100% = 0,0339% per jaar
Jaar 4:
Aantal nieuwe ziektegevallen: 48
Totale populatie at risk: 120.852 -34 -40 -41
(48/ (120.852 – 34 – 40 – 41)) x 100% = 0,0398% per jaar
Jaar 5:
Aantal nieuwe ziektegevallen: 51
Totale populatie at risk: 120.852 -34 -40 -41 -48
(51/ (120.852 – 34 – 40 – 41 – 48)) x 100% = 0,0423% per jaar
Jaar 6 en 7:
Aantal nieuwe ziektegevallen: 68
Totale populatie at risk: 120.852 -34 -40 -41 -48 -51
(68/ (120.852 – 34 – 40 – 41 – 48 – 51))/ 1,3 x 100% = 0,0434% per jaar

b.
Aantal nieuwe ziektegevallen: 282
Totale populatie at risk: 120.852
(282/ 120.852)/ 6,3 x 100% = 0,037% per jaar

c.
Nee, er wordt juist wel uitval verwacht omdat het over een lange periode gemeten wordt
dus er een grote kans is dat er mensen uitvallen.

D.
ID = Aantal nieuwe ziektegevallen tijdens follow up/ totaal geobserveerde personen tijdens
follow up
Dus een verandering in het totaal aantal personen is niet belangrijk voor de formule
