in calculating the incidence of diabetes among the males, do we use the total of male and females for the mid year population or we use only the total male population for the mid year population?

Answer 1

Incidence rate is defined as the measure of the number of new cases divided by total number of population × 1000

In calculating the incidence rate of diabetes among the males only the population of males will be considered because it's apecific about diabetes among males .

For age group less than 35years , number of new cases ( males ) = 2

Total number of population( males ) less than 35years = 10000

Incidence rate = 2/10000× 1000

= 0.2 %

For age group 35-54 , number of new cases ( males ) = 10

Total number of population males with age between 35-54 = 5000

Incidence rate = 10/5000× 1000

= 2%

For age group 54-64 , number of new cases ( males ) = 7

Total number of males population with age between 54-64= 2200

Incidence rate = 7/2200× 1000

= 3.1%

For age group more than 65, number of new cases ( males ) = 53

Total number of males population with age more than 65 of years = 4780

Incidence rate = 53/4780 × 1000

= 11.08%
