Differentiate between morbidity and mortality rates and incidence and prevalence. Explain what is meant by the epidemiologic terms: attack rate and years of potential life lost.

Question

Quizplus · Accepted Answer

The Answer is Morbidity relates to having an illness, injury, or disability. Morbidity measures quantify a population's likelihood of developing or having an illness, injury, disability, or other adverse health condition.
Mortality rates (death rates) are an estimate of the frequency of occurrence of death among a defined population during a specified period.
Incidence is the rate at which new events (e.g., new cases of disease) occur among a population during a specified period.
Prevalence is the proportion of persons among a population who have a particular disease or attribute at a specific point in time or during a specified period.
Attack rate (cumulative incidence) is a measure of incidence most often calculated during the investigation of an acute outbreak of disease. It represents the proportion of a population that experienced a specific illness during a defined time period.
Years of potential life lost is a measure of the impact of premature mortality (death before age 75 or before the average life expectancy is reached) on a population.
