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 prevalence of serious birth defects in this population at the time of birth

Answer 1

The prevalence of serious birth defects in this population at the time of birth is 10%.

Step-by-step explanation:

The prevalence of serious birth defects in this population at the time of birth can be calculated by dividing the number of infants born with serious birth defects by the total number of newborn infants. From the information given, there are 100 infants born with serious birth defects out of 1000 newborn infants.

Prevalence = (Number of infants with serious birth defects / Total number of newborn infants) x 100%

Prevalence = (100 / 1000) x 100% = 10%
