Maternal mortality

Levels of maternal mortality

The number of women and girls who died each year from complications of pregnancy and childbirth declined from 451,000 in 2000 to 287,000 in 2020. These improvements are particularly remarkable in light of rapid population growth in many of the countries where maternal deaths are highest. Still, almost 800 women are dying each day from complications in pregnancy and childbirth, which is equivalent to one every two minutes.

There are large inequalities in maternal survival between regions of the world and countries within those regions. In 2020, sub-Saharan Africa had 545 maternal deaths per 100,000 live births as compared to 4 in Australia and New Zealand. In fact, sub-Saharan Africa alone accounted for 70% of global maternal deaths in 2020.

Progress has stalled, and has been uneven. Regions with the highest burden of maternal mortality will require additional attention and investment to accelerate the rate of reduction. Improvements will be needed in both access and quality, for antenatal care, delivery, and postpartum care. Partnerships between political and community leaders, the health system, and other stakeholders will be needed to reach global goals and reduce these inequities.

Causes of maternal death

Maternal death can be caused directly by postpartum haemorrhage, pre-eclampsia and hypertensive disorders, pregnancy-related infections, and complications of unsafe abortion, as well as indirectly by pre-existing medical conditions aggravated by the pregnancy.

The complications leading to maternal death can occur without warning at any time during pregnancy and childbirth. However, some can be screened and prevented. That is why UNICEF and the partnering organizations are working to ensure that monitoring and identifying high risk pregnancies through antenatal care are available for every pregnant girl and woman.

Most maternal deaths can also be prevented if births are attended by skilled health personnel such as doctors, nurses or midwives. As complications require prompt access to quality obstetric services, these skilled health personnel, who are regularly supervised and have the proper equipment and supplies, can avert maternal death by providing life-saving drugs such as antibiotics, blood transfusions, caesarean sections, and other surgical interventions.

The causes of maternal death are mostly preventable

There are many social, economic, and environmental factors which influence the risk of maternal mortality. This includes social determinants of health, such as income, education, and environmental exposures; access to high-quality health care with sufficient numbers of competent, skilled providers, equipment, and medication; gender norms that devalue women and girls and limit their access to sexual and reproductive health care; and external factors such as political instability, conflicts, and climate change. These factors require intersectoral collaboration to improve maternal health and well-being at every stage.

Lifetime risk of maternal death

The lifetime risk of maternal death is the probability that a 15-year-old girl will die from complications of pregnancy or childbirth over her lifetime; it takes into account both the maternal mortality ratio and the total fertility rate (average number of births per woman during her reproductive years under current age-specific fertility rates). Thus, in a high-fertility setting, a woman faces the risk of maternal death multiple times, and her lifetime risk of death will be higher than in a low-fertility setting. Similar to maternal mortality ratio, the lifetime risk of maternal death varies largely across countries. In 2020, the lifetime risk of maternal death in low income countries as a whole was 1 in 49, compared to 1 in 5,300 in high-income countries. Among regions, women in sub-Saharan Africa face the highest lifetime risk (1 in 41), which is approximately 268 times higher than in Western Europe (1 in 11,000).

The lifetime risk of maternal death ranges from 1 in 5,300 in high income countries to 1 in 49 in low income countries
