Trends in maternal mortality in the United States

Maternal mortality is a major global concern. Although a notable decline in maternal mortality in the United States occurred during the mid-20th century, this progress stalled during the late 20th century. Furthermore, maternal mortality rates have increased during the early 21st century. Around the year 2000 the maternal mortality rate began to rise and has since nearly doubled. Given that at least half of maternal deaths in the U.S. are preventable, the rise in maternal deaths in the U.S. is historic and worrisome. This overview will try to provide a context for understanding the problem of this rise in maternal mortality in the U.S. by briefly discussing how maternal mortality rates are reported from National Vital Statistics data and from a National Surveillance system. Trends and causes of maternal deaths and the difficulty with interpreting these trends will be discussed. (C) 2016 Elsevier Inc. All rights reserved.
