This report by the Maternal Mortality Estimation Inter-agency Group (MMEIG) provides an overview of trends in maternal mortality from 1990 to 2008, based on data from 172 countries. It highlights the progress made in reducing maternal deaths, but also emphasizes the need for further efforts to achieve the Millennium Development Goal target. The report includes definitions, methodological approaches, and findings on maternal mortality rates and measurement challenges.

Maternal Mortality Estimation Inter-agency Group (MMEIG) The 2008 UN inter-agency estimates were produced by the Maternal Mortality Estimation Inter-agency Group (MMEIG): • WHO • UNICEF • UNFPA • The World Bank • Technical Advisory Group
Definition of maternal death • 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. WHO International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, 1992 (ICD-10),
Maternal mortality ratio (MMR) • The MMR is the… Number of maternal deaths per 100,000 live births MDG Target 5.A: Reduce by three-quarters, between 1990 and 2015, the maternal mortality ratio
Measurement challenges • To accurately categorize a death as maternal information is needed regarding: • cause of death • pregnancy status • timing of death in relation to the pregnancy • Large confidence intervals
Sources of maternal mortality data • Maternal mortality data can come from a variety of sources: • Civil registration systems • Household surveys • Censuses • Reproductive-age mortality studies (RAMOS) • Sisterhood methods • Verbal autopsies
Interagency approach to measuring maternal mortality • Civil registration – data adjusted and used directly for estimating MMR • Lacking civil registration data – multilevel regression model developed using available national level data
Interagency approach to measuring maternal mortality • Civil registration – data adjusted and used directly for estimating MMR • Lacking civil registration data – multilevel regression model developed using available national level data % of countries in each category
Interagency approach to measuring maternal mortality • Civil registration – data adjusted and used directly for estimating MMR • Lacking civil registration data – multilevel regression model developed using available national level data % of countries in each category
Overview of the model • Multilevel regression model (for 113 countries) • Three covariates selected from larger list of potential indicators: • Gross domestic product per capita (GDP) • General fertility rate (GFR) • Skilled attendant at delivery (SAB)
Approximately 9 in every 10 maternal deaths in sub-Saharan Africa or South Asia 358,000 maternal deaths worldwide Global distribution of maternal deaths, 2008
Maternal mortality is declining 34% decline
MMRs decline across all developing regions Maternal deaths per 100,000 live births
Conclusion • Substantial progress made: • 34% decline in developing world • 188,000 fewer deaths today than in 1990 • 58 countries are making progress or on-track • But more needs to be done • MDG target requires 5.5% annual decline, but current rate is 2.3% to date • 358,000 maternal deaths, mostly preventable • Every year 45,000 births are not attended by skilled health personnel
