When applying epidemiology and demography to the practice of community health, how is the prevalence rate calculated?
A) (Number of new cases of specified health condition during time interval/Estimated midinterval population at risk) × 1,000
B) (Number of current cases of a specified health condition at a given point in time/Estimated population at risk at same point) × 1,000
C) (Number of deaths of infants aged < 1 year during time interval/Total live births during time interval) × 1,000
D) (Number of deaths from puerperal cases during 1 year/Number of live births during same year) × 100,000
Ans: B
Prevalence rate is calculated as (Number of current cases of a specified health condition at a given point in time/Estimated population at risk at same point) × 1,000. Incidence rate is calculated as (Number of new cases of specified health condition during time interval/Estimated midinterval population at risk) × 1,000. Infant mortality rate is calculated as (Number of deaths of infants aged < 1 year during time interval/Total live births during time interval) × 1,000. Maternal mortality rate is calculated as (Number of deaths from puerperal cases during 1 year/Number of live births during same year) × 100,000.
