Question

For numbers 1-5, name and calculate the appropriate measure of frequency (prevalence, cumulative incidence, or incidence rate) given the following information. 1. Out of 100 people surveyed, 32 had a BMI indicating that they were obese. 2. Of 80 people who traveled to Brazil, 15 developed malaria. 3. Of 120 mothers with breast cancer, 7 breastfed their infants. 4. During the 24 hours after the picnic, 25 of the 100 attendees who ate the peanut butter dessert developed Salmonella infection. 5. Of the 1,400 people with suspected or confirmed Ebola in Liberia, Africa, 700 die from the disease.

Explanation / Answer

1) prevalence = 32/100 = 0.32

2) incidence rate = 15/80 = 0.1875

3) prevalence = 7/120 = 0.0583

4) cumulative incidence = 25/100 = 0.25 per day = 0.01 per hour

5) incidence rate = 700/1400 = 0.5
