The nurse researches the relationship between frequent ingestion of fast foods and obesity. The nurse finds that in a population that eats at least five fast food meals per week on average, the incidence rate of people who are obese is 735/1,000 population. In the population that eats only one fast food meal per week on average, the incidence rate of people who are obese is 245/1,000 population. Based on these findings, what is the relative risk of developing obesity in those who eat at least five fast food meals per week?

The relative risk of developing obesity for those who eat at least five fast food meals per week compared to those who eat only one is calculated by dividing the incidence rate in the exposed group (735/1,000) by the incidence rate in the non-exposed group (245/1,000), which equals 3. This indicates that individuals in the first group are three times more likely to develop obesity than those in the second group.
