When mortality rates are based on vital statistics (e.g., counts of death certificates), the denominator most commonly used is the size of the population at the middle of the time period. In the United States, values of 1,000 and 100,000 are both used for 10 n for most types of mortality rates. Table 3.4 summarizes the formulas of frequently used mortality measures. Prevalence, in epidemiology, the proportion of a population with a disease or a particular condition at a specific point in time (point prevalence) or over a specified period of time (period prevalence). Prevalence is often confused with incidence, which is concerned only with the measure of new cases in a population over a given interval of time. There are two broad types of epidemiological studies: 1. Observational studies – we do not interfere in the process of the disease, but simply observe the disease and the associated factors. 2. Experimental studies – deliberate intervention is made and the effect of such intervention is observed. Observational studies include: Descriptive study and Analytical study – Case control and Types of mortality rates. (go to Outline) There are several different mortality rates used to monitor the level of mortality in populations. In humanitarian emergencies, the following are most commonly used: Crude mortality rate. Counts all deaths All causes. All ages and both sexes.

Other outcomes, such as many types of injuries, occur more often among younger people. The age distribution determines what the most common health problems  Introduction.
