Maternal Mortality Ratio (MMR)
Maternal Mortality Ratio (MMR), often incorrectly referred to as the Maternal Mortality Rate, is the ratio of the number of maternal deaths per 100,000 live births from any cause related to or aggravated by pregnancy or its management, excluding accidental or incidental causes. According to the CIA World Factbook, the MMR includes deaths during pregnancy, childbirth or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, for a specified year. The MMR is used as a measure of the quality of a health care system.
In 2010, countries with highest maternal mortality were: Chad (1,100), Somalia (1,000), Central African Republic, (890), Sierra Leone (890) and Burundi (800).
Lowest rates included Estonia at 2 per 100,000 and Singapore at 3 per 100,000. In the United States, the maternal death rate was 21 maternal deaths per 100,000 live births in 2010. "Lifetime risk of maternal death" accounts for number of pregnancies and risk. In sub-Saharan Africa the lifetime risk of maternal death is 1 in 16, for developed nations only 1 in 2,800.

Famous quotes containing the words maternal, mortality and/or ratio:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
“Antiquity breached mortality with myths.
Narcissus is vocabulary. Hermes decorates
A cornice on the Third National Bank.”
—Allen Tate (1899–1979)
“Personal rights, universally the same, demand a government framed on the ratio of the census: property demands a government framed on the ratio of owners and of owning.”
—Ralph Waldo Emerson (1803–1882)
