To calculate a death rate the number of deaths recorded is divided by the number of people in the population, and then multiplied by , 1, or another convenient figure.

Measurement in epidemiology: prevalence, incidence, risk, impact measures. ISSN Measurement is essential in epidemiology, and this is why detailed knowledge of the different measures that are estimated in this discipline is necessary, since information interpretation and, most importantly, the decisions made in the care of patients depend on it. This article describes the three main groups of measures in epidemiology: frequency, association and potential impact; examples and instructions for their calculation are also provided. Incidence and prevalence are the most significant frequency measures, and can be obtained when both morbidity and mortality of diseases are studied.

Morbidity and mortality are two terms that often get confused. Morbidity refers to disease states, while mortality refers to death. Both terms are commonly used in health- and death-related statistics. Morbidity is any physical or psychological state considered to be outside the realm of normal well-being. The term is often used to describe illness, impairment, or degradation of health. Morbidity is often used in discussing chronic and age-related diseases , which can worsen over time and impact your quality of life.

Measures of disease frequency and disease burden

Epidemiology is based on two fundamental assumptions. First, the occurrence of disease is not random i. Second, the study of populations enables the identification of the causes and preventive factors associated with disease.
