Question

Researchers were interested in the relationship between the consumption of diet soda and blood pressure. They interviewed 2,000 people—1,000 people who drank 1 or more diet sodas per day and 1,000 people who did not drink diet soda. Among those that drank diet soda, 90 people had high blood pressure; in the non-soda drinking group, there were 10 cases of high blood pressure.

Based on this information, what is the prevalence rate of high blood pressure in non-diet soda drinkers?

Answer 1

The prevalence rate of high blood pressure in non-diet soda drinkers is calculated to be 1%, derived from 10 cases of high blood pressure among 1,000 non-diet soda drinkers.

Step-by-step explanation:

The prevalence rate of high blood pressure in non-diet soda drinkers, based on the information provided, can be calculated by dividing the number of non-diet soda drinkers with high blood pressure by the total number of non-diet soda drinkers, and then multiplying the result by 100 to get a percentage. In this case, there are 10 cases of high blood pressure among the 1,000 non-diet soda drinkers.

Prevalence Rate = (Number of Non-Diet Soda Drinkers with High Blood Pressure / Total Number of Non-Diet Soda Drinkers) x 100

Prevalence Rate = (10 / 1,000) x 100 = 1%.

The prevalence rate of high blood pressure among individuals who do not drink diet soda is therefore 1%.
