Proportionate mortality rate = (Number of deaths due to MVA / Total number of deaths) x 100 Proportionate mortality rate = (122 / 452) x 100 Proportionate mortality rate = (0.269) x 100 Proportionate mortality rate = 26%
The Correct Answer and Explanation is:
The Proportionate Mortality Rate (PMR) is a measure used to determine the proportion of deaths attributed to a specific cause in relation to the total number of deaths in a given population over a defined period. In this case, you’re looking at the number of deaths due to Motor Vehicle Accidents (MVA) and comparing them to the total number of deaths.
Formula:
The formula to calculate PMR is: Proportionate Mortality Rate=(Number of deaths due to MVATotal number of deaths)×100\text{Proportionate Mortality Rate} = \left(\frac{\text{Number of deaths due to MVA}}{\text{Total number of deaths}}\right) \times 100Proportionate Mortality Rate=(Total number of deathsNumber of deaths due to MVA)×100
Given:
- Number of deaths due to MVA = 122
- Total number of deaths = 452
Calculation:
Now, we can plug the values into the formula: Proportionate Mortality Rate=(122452)×100\text{Proportionate Mortality Rate} = \left(\frac{122}{452}\right) \times 100Proportionate Mortality Rate=(452122)×100 Proportionate Mortality Rate=0.269×100\text{Proportionate Mortality Rate} = 0.269 \times 100Proportionate Mortality Rate=0.269×100 Proportionate Mortality Rate=26.9%\text{Proportionate Mortality Rate} = 26.9\%Proportionate Mortality Rate=26.9%
So, the Proportionate Mortality Rate due to Motor Vehicle Accidents is 26.9%.
Explanation:
The Proportionate Mortality Rate (PMR) is important because it helps public health authorities understand the relative importance of different causes of death in a population. In this case, a PMR of 26.9% indicates that approximately 27% of all deaths in the studied population were due to Motor Vehicle Accidents.
This statistic is often used in epidemiology to identify the burden of specific diseases or causes of death, which can help in the allocation of resources for prevention and health interventions. For example, a high PMR for MVAs might prompt increased efforts toward road safety, traffic law enforcement, or public education about driving hazards.
The Proportionate Mortality Rate is not an absolute measure of risk or disease burden; it only provides a snapshot of how one cause compares to others in terms of overall mortality. It is essential to complement PMR with other measures, such as the mortality rate or cause-specific mortality rate, to get a fuller picture of the public health landscape.
