What is age-specific mortality rate?

What is age-specific mortality rate?

An age-specific mortality rate is a mortality rate limited to a particular age group. The numerator is the number of deaths in that age group; the denominator is the number of persons in that age group in the population.

How do you calculate age-specific mortality rate?

To calculate the age-standardized mortality rate (ASMR), we must first calculate the age-specific (mortality) rates for each age group by dividing the number of deaths by the respective population, and then multiplying the resulting number by 100,000: Age-specific rate, 0 to 39 years.

How do you calculate specific mortality rate?

1 to compute the age-specific death ratios. They are computed by dividing the number of deaths due to a specific cause by the total deaths in the same interval (and multiplying by 100).

What does high mortality rate mean?

When an event or a disease causes more deaths than expected, it’s called “excess mortality.” COVID-19 is a good example of an illness causing excess mortality. In some hard-hit countries, data shows that COVID-19 caused 50% more deaths than were expected in a specific period of time.

Why is age-specific mortality rate important?

An age-adjusted rate is the best summary statistic for comparing the impact of dis- eases like heart disease, cancer, stroke and diabetes that are heavily influenced by age. Age-adjusted rates are useful for identify- ing differences that are due to environmen- tal or behavioral risk factors instead of age.

What is the difference between morbidity and mortality?

Morbidity and mortality are two terms that often get confused. Morbidity refers to an illness or disease. Mortality refers to death. Both terms are often used in statistics.

What is the disease specific mortality rate?

Definition: CAUSE-SPECIFIC DEATH RATE is the number of deaths from a specified cause per 100,000 person-years at risk.

How do you calculate deaths per 100k?

CRUDE DEATH RATE is the total number of deaths to residents in a specified geographic area (country, state, county, etc.) divided by the total population for the same geographic area (for a specified time period, usually a calendar year) and multiplied by 100,000.

What is age-adjusted mortality rate?

CDRs are usually expressed as a rate per 1,000 or 100,000 population. CDRs for individual age cohorts, called age-specific death rates (ASDRs), are the ratio of the number of deaths in a given age group to the population of that age group, again usually expressed per 1,000 or 100,000 population.

What are the 10 leading causes of morbidity and mortality?

According to the CDC , the top 10 causes of death in the United States for the year 2018 were:

  • heart disease.
  • cancer.
  • unintentional injury.
  • chronic lower respiratory diseases.
  • stroke.
  • Alzheimer’s disease.
  • diabetes.
  • influenza and pneumonia.

How is the age specific death rate calculated?

This results in an age-specific death rate (ASDR) per 100,000 population for each age group. That is, for each age group, ASDR = deaths in age group ÷ estimated population of that age group × 100,000.

What’s the typical mortality pattern for all age groups?

The typical mortality pattern over all age groups has a J-shape. Mortality is high among infants and young children, after which it declines rapidly, reaching its lower level usually between ages 5-14. As a general rule,mortality rates start to increase exponentially beyond age 35 or so.

Which is the correct definition of cause specific mortality?

Cause-specific mortality rate The cause-specific mortality rate is the mortality rate from a specified cause for a population. The numerator is the number of deaths attributed to a specific cause. The denominator remains the size of the population at the midpoint of the time period.

How are mortality rates used to compare populations?

Mortality rates can be used to compare the rates in one area with the rates in another area, or to compare rates over time. However, because mortality rates obviously increase with age, a higher mortality rate among one population than among another might simply reflect the fact that the first population is older than the second.
