Question

A specific kind of colon cancer known as colon cancer X was the focus of research on how a vegetarian diet affected its growth. They enlisted 1,500 vegetarians between the ages of 35 and 40. All participants were checked prior to the study's start, and 29 of them tested positive for colon cancer X. They continued to be treated. A second screening was held five years later with all 1,500 participants continuing following a vegetarian diet, and at that time, 58 more persons had been diagnosed with colon cancer X.

At the beginning of the investigation, what was the prevalence of colon cancer X in the sample? Add the right formula in your answer along with your calculations and conclusions.

Answer 1

The prevalence of colon cancer X at the beginning of the study was 1.93%, calculated by dividing the number of existing cases (29) by the total number of participants (1,500).

Step-by-step explanation:

To calculate the prevalence of colon cancer X in the study group at the beginning of the research, one would use the following formula:

Prevalence = (Number of existing cases at the start of the study) / (Number of people in the study group)

In this case, there were 29 existing cases of colon cancer X among the 1,500 participants. Thus, the calculation would be:

Prevalence = 29 cases / 1,500 participants

Prevalence = 0.0193

Expressed as a percentage, the prevalence of colon cancer X at the beginning of the study was 1.93%. This means that out of every 100 participants, approximately 1.93 were diagnosed with colon cancer X at the start of the investigation.
