Maternal mortality ratio
Maternal Mortality Ratio
The Maternal Mortality Ratio (MMR) (pronunciation: məˈtɜːrnəl mɔːˈtælɪti ˈreɪʃɪoʊ) is a measure of the number of deaths of women due to pregnancy-related causes per 100,000 live births.
Etymology
The term is derived from the Latin word 'mater' meaning 'mother', and the Latin word 'mors' meaning 'death'. The word 'ratio' is derived from the Latin word 'ratiō', meaning 'reason' or 'calculation'.
Definition
The Maternal Mortality Ratio is a key performance indicator for efforts to improve the health and safety of mothers before, during, and after childbirth. It measures the risk of death once a woman has become pregnant.
Calculation
The Maternal Mortality Ratio is calculated by dividing the number of maternal deaths by the total number of live births in the same period and multiplying the result by 100,000.
