Answer 1

Answer

i: It should be prevalence given as number of women in town of Framingham who reported having heart disease in recent health survey /estimated number of women residents of Framingham during same period because as per definition prevalence is the proportion of a population which is affected by a medical condition and It is calculated by comparing the number of people having the condition with the total number of people studied which is shown in option i.

ii: It should be incidence density/incidence rate as Number of women in Framingham study who have developed heart disease in last year is representing incidence density and number of person-years contributed through last year by women initially enrolled in Framingham study is representing incidence rate

iii: It should be mortality rate as we are measuring the number of deaths in a particular population.
