Question

A city contains 100,000 people (45,000 males and 55,000 females), and 1,000 people die per year (600 males and 400 females). There were 50 cases (40 males and 10 females) of lung cancer per year, of whom 45 died (36 males and 9 females). Compute:
a. Crude mortality rate
b. Sex-specific mortality rate
c. Cause-specific mortality rate for lung cancer
d. Case fatality rate for lung cancer
e. PMR for lung cancer

Answer 1

Answer:a)0.001

b) males=1.

Females = 1

c) 0.9

d) 4×10^-5

e)0.045

Step-by-step explanation:a) crude death= Number of death/Number of individuals = 1000/100000= 0.001

b)sex specific death rate= numbered deaths of males/ number of deaths of males= 600/600= 1

c)case specific = 45/50=0.9

d)cause specific= Number of people dying from lung cancer/number of people with disease=45/100000=4×10^-5

e) pmr= number of deaths from specific disease÷total number of death=45/1000=0.045
