Changes in pregnancy mortality ascertainment: United States, 1999-2005.

Objective: To estimate mortality ratios for all reported pregnancy deaths in the United States, 1999-2005, and to estimate the effect of the 1999 implementation of International Classification of Diseases, Tenth Revision (ICD-10) and adoption of the U.S. Standard Certificate of Death, 2003 Revision, on the ascertainment of deaths resulting from pregnancy.

Sexual and reproductive health of persons aged 10-24 years - United States, 2002-2007.

This report presents data for 2002-2007 concerning the sexual and reproductive health of persons aged 10-24 years in the United States. Data were compiled from the National Vital Statistics System and multiple surveys and surveillance systems that monitor sexual and reproductive health outcomes into a single reference report that makes this information more easily accessible to policy makers, researchers, and program providers who are working to improve the reproductive health of young persons in the United States. The report addresses three primary topics: 1) current levels of risk behavior and health outcomes; 2) disparities by sex, age, race/ethnicity, and geographic residence; and 3) trends over time.

Overview of maternal morbidity during hospitalization for labor and delivery in the United States: 1993-1997 and 2001-2005.

Objective: To assess progress toward meeting the U.S. Healthy People 2010 objective of reducing the rate of maternal morbidity at delivery hospitalization by comparing National Hospital Discharge Survey data from two time periods.

Identification of severe maternal morbidity during delivery hospitalizations, United States, 1991-2003.

Objective: This investigation aimed to identify pregnancy complications and risk factors for women who experienced severe maternal morbidity during the delivery hospitalization and to estimate severe maternal morbidity rates.

Study Design: We used the National Hospital Discharge Survey for 1991-2003 to identify delivery hospitalizations with maternal diagnoses and procedures that indicated a potentially life-threatening diagnosis or life-saving procedure.

Results: For 1991-2003, the severe maternal morbidity rate in the United States was 5.

Pregnancy-related mortality among women with multifetal pregnancies.

Objective: To examine the relative risk of pregnancy-related mortality between multifetal pregnancies and singleton pregnancies.

Methods: We used data from the Centers for Disease Control and Prevention's Pregnancy Mortality Surveillance System to examine singleton and multifetal pregnancy-related deaths among women with a live birth or fetal death from 1979-2000. The plurality-specific (singleton or multifetal) pregnancy-based mortality ratio was defined as the number of pregnancy-related deaths per 100,000 pregnancies with a live birth.

An assessment of pregnancy-related mortality in the United States.

Deaths from pregnancy complications remain an important public health concern. Nationally, two systems collect information on the number of deaths and characteristics of the women who died from complications of pregnancy. The Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS) reports maternal mortality through the National Vital Statistics System (NVSS); CDC National Center for Chronic Disease Prevention and Health Promotion's Pregnancy Mortality Surveillance System (PMSS) conducts epidemiological surveillance of pregnancy-related deaths.
