 Many variables used by ﬁeld epidemiologists can be Categorical variables
 Are three frequency measures that are used to characterize the occurrence of health events in a population. Incidence, prevalence, mortality rates
 Categorical variables have to be summarized with Frequency measure
 Common frequency measures are: Absolute count, ratio, proportion, rate
 A measure of central location provides a single value that summarizes an entire distribution of data. Frequency measure
 Frequency measure also known as Tools of demography
 Simple counts of events Absolute count
 A number that shows the relationship between two numbers in which one is divided by the other. Ratio
 In the language of indicators, the term _______ is reserved for measures wherein the numerator is not a part of denominator. Ratio
 When a proportion is multiplied by 100, it is called a Percentage
 A special type of ratio in which the numerator is part of the denominator Proportion
 Refers to the occurrence of events over a given interval of time relative to the total person time of exposure/ at risk. Rate
 Crude rates denominator is Total population
 Specific rates denominator is Population of subgroups
 Constructed to permit fair comparison between 2 groups which diﬀer in some important characteristics Adjusted Standardized rates
 The rate describes the total population, which is used as the denominator in the computation Crude rates
 Describes only a speciﬁc sub – group of the total population. Specific rates
 The denominator include only those belonging to the sub – group being studied. Specific rates
 Population who become ill Incidence
 Ill at the given time Prevalence
 Also known as attack rate Incidence proportion or cummulative incidence
 It is the proportion disease of free individuals who contract the disease within a speciﬁed period of time. Incidence proportion or cummulative incidence
 Measures the average risk of developing the disease. Incidence proportion
 Assume a ﬁxed population and no completing risks Incidence proportion
 The period/ duration of exposure of all subjects to the exposure factor are the same for all subjects. Fixed population
 It measures the rate at which new cases occur Incidence rate or incidence density
 Incidence rate or density answer the question? How fast the disease occur
 Measures the proportion of existing cases of a disease in the population at a particular point in time. Point prevalence
 Useful in describing the magnitude of chronic conditions existing in a population at a point in time Point prevalence
 Measures the residuals of an illness Point prevalence
 Does not measure the risk of developing the disease Point prevalence
 Refers to prevalence measured over an interval of time Period prevalence
 It is the proportion of persons with a particular disease or attribute at any during the interval. Period prevalence
 It measures the frequency of occurrence of death in a deﬁned population during a speciﬁed interval Mortality rate
 Is the mortality rate from all causes of death for a population. Crude mortality
 It is mortality rate from specified cause for a population. Cause-specific mortality rate
 Measures the proportion of total deaths occurring in a particular population group or from particular cause. Proportionate mortality
 Aﬀected by the nature of the disease, diagnostic ascertainment and level of reporting in the population. Case fatality rate
 Time element not annual duration of the particular disease Case fatality rate
 Maternal mortality ratio reflects the level of Obstetric risk
 Measures the occurrence of maternal deaths. Maternal mortality ratio
 Include deaths from 28 days of life to less than one year. Post – neonatal Mortality Ratio
 Deaths under 28 days of life. Neonatal mortality ratio
