Number of deaths occurring in a given population at risk during a specified time period also known as the recall period.

Usually expressed as deaths per 1, persons per month or per year. World Health Organization. This comparison of two proportionate mortalities is called a proportionate mortality ratio ,or PMR for short. A PMR greater than 1. For example, construction workers may be more likely to die of injuries than the general population.

However, PMRs can be misleading, because they are not based on mortality rates. Those workers with a high injury-related proportionate mortality very likely have lower proportionate mortalities for chronic or disabling conditions that keep people out of the workforce.

In other words, people who work are more likely to be healthier than the population as a whole — this is known as the healthy worker effect. Using the data in Table 3. Data Sources: CDC. MMWR ;2 No. Deaths: Preliminary data for National Vital Statistics Reports; vol.

Years of potential life lost YPLL is one measure of the impact of premature mortality on a population. Additional measures incorporate disability and other measures of quality of life. YPLL is calculated as the sum of the differences between a predetermined end point and the ages of death for those who died before that end point. The two most commonly used end points are age 65 years and average life expectancy.

The use of YPLL is affected by this calculation, which implies a value system in which more weight is given to a death when it occurs at an earlier age. In , the remaining life expectancy was Because different populations may also have different age distributions, YPLL rates are usually age-adjusted to eliminate the effect of differing age distributions.

The YPLL rate represents years of potential life lost per 1, population below the end-point age, such as 65 years. YPLL rates should be used to compare premature mortality in different populations, because YPLL does not take into account differences in population sizes. Use the data in Tables 3.

Section 3: Mortality Frequency Measures Mortality rate A mortality rate is a measure of the frequency of occurrence of death in a defined population during a specified interval. The formula for the mortality of a defined population, over a specified period of time, is: Deaths occurring during a given time period Size of the population among which the deaths occurred. Unintentional-injury-specific mortality rate for the entire population This is a cause-specific mortality rate.

This is an age-specific mortality rate. This is a sex-specific mortality rate. Exercise 3. Calculate the homicide-related death rates for males and for females. What type s of mortality rates did you calculate in Question 1? Calculate the ratio of homicide-mortality rates for males compared to females. Interpret the rate you calculated in Question 3 as if you were presenting information to a policymaker.

Number of deaths attributed to a particular disease during specified period Number of new cases of the disease identified during the specified period. Number of cause-specific deaths among the incident cases Total number of incident cases.

Deaths caused by a particular cause Deaths from all causes. Years of potential life lost Population under age 65 years.
