If D equals the number of deaths in 2009 and P equals the population at the midpoint of 2009 and A equals the number of persons aged 15-24, then the crude death rate per 100,000 population would be: A. (D/P) × 100,000 B. (A/P) × 100,000 C. (P/D) × 100,000 D. (P/A) X 100,000 The number of deaths due to a disease that occurs among persons who are afflicted with the condition is known as: A.

Incidence and prevalence rates can also be used to compare the rates of disease across different...
Incidence and prevalence rates can also be used to compare the rates of disease across different settings (places), people, or time. We therefore need measures of comparison. The ratio of two measures of disease frequency is called the relative risk. The difference between two measures of disease frequency is called the risk difference, or rate difference. In some cases, it involves a measure in an exposed group (or groups) and a measure in an unexposed or comparison group. In other...
