per 1000 population
Which of the following is NOT a factor influencing the Crude Death Rate?
Air pollution levels
What is the calculation for the Infant Mortality Rate?
No of deaths in the first year of life × 1000 No. of live births
What is the impact of an aging population on the Crude Death Rate?
It increases the Crude Death Rate
What does incidence measure in a population?
The frequency by which unaffected persons develop a particular disease
What is incidence usually used to measure?
The frequency of chronic diseases
How is the incidence of chronic diseases measured?
Through a follow-up survey study
What does prevalence measure in a population?
The amount of disease already present in a population
Why is incidence a good measure for chronic diseases?
Because it measures the accumulated cases by time for both new and old cases
What is the difference between incidence and prevalence?
Incidence measures the frequency of new cases, while prevalence measures the total cases
What is the formula to calculate the Under-5 Mortality Ratio (U5MR)?
Number of deaths of children in the first 5 years of life ×1000 / Number of live births
What does the Cause Specific Mortality Rate measure?
The number of deaths from a specific disease in a certain year and locality
What is the formula to calculate the Cause Specific Mortality Rate from a specific disease?
Number of deaths from a specific disease ×100,000 / Mid-year population
What does the Proportionate Death Rate measure?
The proportion of deaths from a specific disease in a certain year and locality
What is the formula to calculate the Case Fatality Rate?
Number of deaths from a specific disease ×100 / Number of cases of this disease
What is the formula to calculate the Maternal Mortality Ratio (MM Ratio)?
Number of deaths of mothers due to causes related to pregnancy, labor or puerperium / Total number of live births ×100,000
What does incidence measure in a population?
The frequency by which unaffected persons develop a particular disease
What is prevalence used to measure?

What is the incidence rate used to measure?
The frequency of chronic diseases per time
What is the main difference between incidence and prevalence?
Incidence measures new cases, while prevalence measures existing cases
What is a possible reason for a decrease in the incidence rate of a disease?
Change in the disease etiology
Which of the following is a characteristic of prevalence?
It measures the total amount of disease in a population
What is the relationship between incidence rate and prevalence?
Prevalence depends on the incidence rate and the duration of illness
Why is incidence rate a good measure for chronic diseases?
It measures the accumulated cases over time
