5. In a baseline mass screening of 9000 adults in Gilbert, AZ, 720 were found to have diabetes, 1020 had high blood pressure, and 3,700 were categorized as obese. During the next 5 years, 190 more of the initially examined adults developed diabetes. Assume that the 190 new cases of diabetes were diagnosed evenly across the 5-year period. a. (5 points) What was the prevalence of diabetes (per 100 adults) at the time of screening? Interpret this number in a sentence. b. (5 points) What was the cumulative 5-year incidence rate of diabetes in previously screened adults? Interpret this number in a sentence. c. (5 points) What was the average annual incidence of diabetes? (1) estimate by using the cumulative 5-year incidence (risk), and then (2) using person-years at risk to calculate a true rate. Interpret both measures in a sentence. The average annual incidence of diabetes using the cumulative 5-year incidence 190 l 5 = 38% The average annual incidence of diabetes using person-years at risk 190 \"(9,000-720) x 5) = 0.0045893
