Maternal mortality has not improved in the US and appears to be increasing, according to a recent study that examined trends by socioeconomic characteristics and cause of death in several states and the District of Columbia. The observational study compared data from 2008-2009 with 2013-2014 for 27 states and the District of Columbia that had comparable reporting of maternal mortality throughout the period. Maternal mortality rates were computed per 100,000 live births. Researchers found:
- Study population included 1,687 maternal deaths and 7,369,966 live births.
- The maternal mortality rate increased by 23% from 20.6 maternal deaths in 2008-2009 to 25.4 in 2013-2014.
- The majority of the increase was among women aged ≥40 years and for nonspecific causes of death.
- Maternal mortality rates for women aged ≥40 years increased by 90% during the study period but did not increase for women aged <40 years.
