Question

A total of 2,123,323 deaths were recorded in the United States in 1987. The mid-year population was estimated to be 243,401,000. HIV-related mortality and population data by age for all races and for black males are shown in Table 3. Note: Population figures are “x1,000 (example black males population for 0-4 is 1,393,000).   (5 points)

b. HIV-(cause)-specific mortality rate for the entire population?

c. HIV-specific mortality among 25- to 34-year-olds?

d. HIV-specific mortality among 25- to 34-year-old black males?

Answer 1

b. HIV (cause)-specific mortality rate for the entire population

HIV specific mortality rate = Number of HIV deaths / population X 10ⁿ

HIV specific mortality rate = 13 468 / 243,401,000 X 100,000

= 5.5

HIV (cause) specific mortality rate is 5.5 per 100,000 population.

c. HIV-specific mortality among 25- to 34-year-olds

HIV related mortality rate = No.of HIV death in 25 to 34 year old / Population of 25 to 34 year olds X 10ⁿ

HIV related mortality rate = 5026 / 43315,000 X 100,000

= 11.6

HIV related mortality rate among 25 to 34-year-olds is 11.6 per 100,000 population.

d. HIV-specific mortality among 25- to 34-year-old black males

HIV related mortality rate = No.of HIV death in 25 - 34 years old in black males / Population of 25 -34-year-old black males X 10ⁿ

HIV related mortality rate = 1326 / 2549000 X 100,000

= 52.02

HIV related mortality rate among 25-34-year-old black males is 52.02 per 100,000 population.
