How do you calculate age-specific mortality?

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.

What is age-specific mortality?

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 risk of dying?

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.

How do you calculate IMR?

Infant mortality rates are calculated as the number of deaths in the first year of life divided by the number of live births, multiplied by 1000.

What is the formula of specific death rate?

1 can be used to compute the age-cause-specific death rates by simply dividing the number of deaths by cause in a particular age group by the corresponding mid-year population and multiplying by 1000.

Age Specific Death Rate [ASDR]

What is specific death rate?

Definition: CAUSE-SPECIFIC DEATH RATE is the number of deaths from a specified cause per 100,000 person-years at risk. The numerator is typically restricted to resident deaths in a specific geographic area (country, state, county, etc.).

How is MMR and IMR calculated?

Maternal mortality ratio = (Number of maternal deaths / Number of live births) X 100,000 The maternal mortality ratio can be calculated directly from data collected through vital registration systems, household surveys or other sources.

What is IMR and MMR?

Infant Mortality Rate (IMR) and Maternal Mortality Ratio (MMR), 1981 - 2020. The infant mortality rate has decreased from 9.7 per 1000 live births in 1981 to 2.0 in 2020 while the maternal mortality ratio has fluctuated between 0 and 11.2 per 100000 live births in the past 40 years.

How is MMR rate calculated?

To compute the rate per 100,000 live births, the numerator is divided by the denominator and multiplied by 100,000. The numerator requires information on number of maternal death (3). The denominator should include only live births.

How do you calculate age-specific incidence?

C.

An age-specific rate is calculated by dividing the total number of health events for the specific age-group of interest by the total population in that age group.

How do you calculate lifetime risk of maternal death?

It can be approximated by multiplying the maternal mortality rate by the length of the reproductive period (around 35 years). Thus, the lifetime risk is calculated as [1-(1-maternal mortality rate)35].

Is IMR and MMR same?

Various health care schemes of the Indian government are aimed at reducing the maternal mortality ratio (MMR) and intact mortality rate (IMR) in the country. Special focus is being given to states with poor public health indicators and high numbers of people living below the poverty line.

What is the infant mortality rate IMR?

About Infant Mortality

The infant mortality rate is the number of infant deaths for every 1,000 live births. In addition to giving us key information about maternal and infant health, the infant mortality rate is an important marker of the overall health of a society.

What is IMR and NMR?

Abstract. Neonatal mortality rate (NMR) or infant mortality rate (IMR) are the rate of deaths per 1,000 live births at which babies of either less than four weeks or of one year of age die, respectively. The NMR and IMR are commonly accepted as a measure of the general health and wellbeing of a population.

Why is MMR a ratio?

Definition: The maternal mortality ratio (MMR) is defined as the number of maternal deaths during a given time period per 100,000 live births during the same time period.

What is MMR report?

Maternal Mortality Rate (MMR) is defined as the number of maternal deaths per 100,000 live births due to pregnancy or termination of pregnancy, regardless of the site or duration of pregnancy. The maternal mortality rate is used to represent the risk associated with pregnancy among women.

Why is age specific mortality rate important?

Rates Important? Age-adjusted rates allow you to compare health statistics (like death rates) between population groups, even though the size of the groups or the age of group members might be very different.

What is IMR stands for?

Infant mortality rate (per 1000 live births)

What does the IMR denote?

Infant mortality rate (IMR) is the number of deaths per 1,000 live births of children under one year of age. The rate for a given region is the number of children dying under one year of age, divided by the number of live births during the year, multiplied by 1,000.

Is infant mortality rate a ratio?

Infant mortality rate is strictly speaking not a rate (i.e. the number of deaths divided by the number of population at risk during a certain period of time) but a probability of death derived from a life table and expressed as rate per 1000 live births.

What is the current MMR?

India's maternal mortality ratio (MMR) has improved to 103 in 2017-19, from 113 in 2016-18. This is according to the special bulletin on MMR released by the Registrar General of India March 14, 2022.

What is the difference between maternal mortality rate and maternal mortality ratio?

The pregnancy-related mortality ratio (PRMR) and the maternal mortality ratio (MMR) are calculated by dividing the total pregnancy-related mortality rate and the total maternal mortality rate by the general fertility rate for the same period and are expressed per 100,000 births.

What is an example of maternal mortality rate?

Example: The town of Fecundaville has 1,000 people. Each woman has ten children over her lifetime. The probability of dying from pregnancy is 1 out of 1,000. The lifetime risk of maternal death is 10 * (1/1,000) = 1%.

What is lifetime risk of maternal mortality?

A woman's lifetime risk of maternal death is the probability that a 15 year old woman will eventually die from a maternal cause. In high income countries, this is 1 in 5400, versus 1 in 45 in low income countries.

What is the difference between maternal death and pregnancy related death?

Maternal death and maternal mortality mean the same thing. Pregnancy-related death is when a pregnant or birthing person dies during pregnancy or within 1 year after the end of their pregnancy from health problems related to pregnancy.
