Maternal death is defined by the World Health Organization (WHO) as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes."
There are two performance indicators that are sometimes used interchangably: maternal mortality ratio and maternal mortality rate, which confusingly both are abbreviated "MMR". The world maternal mortality rate has declined 44% since 1990, but still every day 830 women die from pregnancy or childbirth related causes. According to the United Nations Population Fund (UNFPA) this is equivalent to "about one woman every two minutes and for every woman who dies, 20 or 30 encounter complications with serious or long-lasting consequences. Most of these deaths and injuries are entirely preventable."
UNFPA estimated that 289,000 women died of pregnancy or childbirth related causes in 2013. These causes range from severe bleeding to obstructed labour, all of which have highly effective interventions. As women have gained access to family planning and skilled birth attendance with backup emergency obstetric care, the global maternal mortality ratio has fallen from 380 maternal deaths per 100,000 live births in 1990 to 210 deaths per 100,000 live births in 2013, and many countries halved their maternal death rates in the last 10 years.
Worldwide mortality rates have been decreasing in modern age. High rates still exist, particularly in impoverished communities with over 85% living in Africa and Southern Asia. The effect of a mother's death results in vulnerable families and their infants, if they survive childbirth, are more likely to die before reaching their second birthday.
Factors that increase maternal death can be direct or indirect. Generally, there is a distinction between a direct maternal death that is the result of a complication of the pregnancy, delivery, or management of the two, and an indirect maternal death. that is a pregnancy-related death in a patient with a preexisting or newly developed health problem unrelated to pregnancy. Fatalities during but unrelated to a pregnancy are termed accidental, incidental, or nonobstetrical maternal deaths.
The most common causes are postpartum bleeding (15%), complications from unsafe abortion (15%), hypertensive disorders of pregnancy (10%), postpartum infections (8%), and obstructed labour (6%). Other causes include blood clots (3%) and pre-existing conditions (28%). Indirect causes are malaria, anaemia,HIV/AIDS, and cardiovascular disease, all of which may complicate pregnancy or be aggravated by it.
