Question

Consider a group of 1,000 newborn infants. 100 infants were born with serious birth defects and 20 of these 100 developed general complications during the first year of life. 90 of the 900 remaining infants without any birth defects also developed general complications during the first year of life.

Calculate the incidence of general complications in this population

Answer 1

The incidence of general complications in this population is 11%.

Step-by-step explanation:

The incidence of general complications in this population can be calculated by dividing the total number of infants who developed general complications by the total number of newborn infants.

Given that 20 infants with birth defects and 90 infants without birth defects developed general complications, the total number of infants who developed general complications is 20 + 90 = 110.

The total number of newborn infants is 1000.

Therefore, the incidence of general complications in this population is 110/1000 = 0.11 or 11%.
