EPIDEMIOLOGY1
Answer to the question number 1:
Prospective Cohort Study
Answer to the question number 2:
Absolute Risk = (755/ 7550) X 100
= 10 %
Answer to the question number 3:
Absolute Risk = (378/ 7570) X 100
= 5.0 % (After rounding off)
Answer to the question number 4:
Relative Risk
Answer to the question number 5:
Relative Risk = (Absolute risk in lowest quintile/ Absolute risk in Highest quintile)
= (10/ 5)
= 2.0
Answer to the question number 6:
Absolute risk difference = Absolute risk in lowest quintile - Absolute risk in Highest quintile
= (10 % - 5 %)
= 5 %
Hence, the answer is 0.05 [5.0 %]
Answer to the question number 7:

EPIDEMIOLOGY2
The risk of developing Hearing loss is “x-times” higher in men with the lowest intake of
dietary Niacin compared to men with the highest intake of dietary Niacin.
Answer to the question number 8:

Answer to the question number 9:
Confounder
Answer to the question number 10:
Effect Modifier
Answer to the question number 11:
Total number of people = (2542+ 3267+ 2725+ 1403) = 9937
Total number of death = (6+ 17+ 25+ 122) = 170
∴Crude death rate in population A per 1000 = (170/ 9937) X 1000
= 17.1
Answer to the question number 12:
Age- specific death rate for 0 -20 years age group (per 1000) in Population A,
= (6 / 2542) X 1000
= 2.4 (After rounding off)
Answer to the question number 13:
BOTH a and c are correct.
Answer to the question number 14:
