The mayor of Baby City is interested in comparing the infant mortality rate (infants are defined as babies younger than the age of 12 months) of Baby City with the infant mortality rate of Adult City.He argues that the age distributions of these cities are very different and therefore asks you to calculate the age-adjusted infant mortality rate.What is the best approach?
A) Use direct adjustment.
B) Use indirect adjustment.
C) Calculate the standardized mortality ratio.
D) Explain that no age adjustment is needed when comparing with age-specific mortality rates.
E) Use the World Health Organization standard population to calculate an adjusted rate.
Infant Mortality Rate
is the number of deaths of infants under one year old per 1,000 live births in a given year.
Age-Adjusted
A statistical process used to compare two or more populations at one point in time or one population over time after factoring out the influence of age.
Direct Adjustment
A statistical method used to eliminate the effects of confounding variables by standardizing to a common distribution.

Final Answer :
D
Explanation :
Adjusted rates are calculated to compare the overall (all ages) mortality rates in two different places that have different age distributions.However,if age-specific mortality rates are to be compared,there is no need to adjust for age.In this example,infant mortality rates can be directly compared because both rates are age specific.
