Maternal Mortality Rate is calculated by:
|A|| Maternal deaths/1000 total birth|
|B|| Maternal deaths/1000 live births|
|C|| Maternal deaths/100000 live births|
|D|| Maternal deaths/100000 total birth|
MATERNAL MORTALITY RATE
According to WHO, a maternal death is defined as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incident ill causes".
Maternal mortality rate measures the risk of women dying from "puerperal causes" and is defined as :
Ideally the denominator should include all deliveries and abortions.,
The maternal mortality rate should be expressed as a rate per 1000 live births. In developed countries, MMR has declined significantly. Because of this decline, they use the multiplying factor 100,000 instead of 1000 to avoid fractions in calculating MMR.
