  • Prevalence Estimates of Gestational Diabetes Mellitus in the United States, Pregnancy Risk Assessment Monitoring System (PRAMS), 2007-2010[1] "Gestational diabetes mellitus (GDM) prevalence in 2010 was 4.6% as reported on the birth certificate, 8.7% as reported on the PRAMS questionnaire, and 9.2% as reported on either the birth certificate or questionnaire. The agreement between sources was 94.1% (percent positive agreement = 3.7%, percent negative agreement = 90.4%). There was no significant difference in GDM prevalence between 2007-2008 (8.1%) and 2009-2010 (8.5%, P = .15). Our results indicate that GDM prevalence is as high as 9.2% and is more likely to be reported on the PRAMS questionnaire than the birth certificate. We found no statistical difference in GDM prevalence between the 2 phases. Further studies are needed to understand discrepancies in reporting GDM by data source." Maternal Diabetes
  • Searching for the Definition of Macrosomia through an Outcome-Based Approach[2] "Macrosomia has been defined in various ways by obstetricians and researchers. The purpose of the present study was to search for a definition of macrosomia through an outcome-based approach. In a study of 30,831,694 singleton term live births and 38,053 stillbirths in the U.S. Linked Birth-Infant Death Cohort datasets (1995-2004), we compared the occurrence of stillbirth, neonatal death, and 5-min Apgar score less than four in subgroups of birthweight (4000-4099 g, 4100-4199 g, 4200-4299 g, 4300-4399 g, 4400-4499 g, 4500-4999 g vs. reference group 3500-4000 g) and birthweight percentile for gestational age (90th-94th percentile, 95th-96th, and ≥97th percentile, vs. reference group 75th-90th percentile). There was no significant increase in adverse perinatal outcomes until birthweight exceeded the 97th percentile. A birthweight greater than 4500 g in Whites, or 4300 g in Blacks and Hispanics regardless of gestational age is the optimal threshold to define macrosomia. A birthweight greater than the 97th percentile for a given gestational age, irrespective of race is also reasonable to define macrosomia. The former may be more clinically useful and simpler to apply." Birth - Macrosomia | Birth Weight

  • Crude death rates for children aged 1 to 19 years did not change significantly between 2010 and 2011.
  • Unintentional injuries and homicide were the first and second leading causes of death, respectively, in this age group.

Intended and Unintended Births

The following data is from the National Center for Health Statistics report "Intended and unintended births in the United States: 1982-2010".[4] Data used in report primarily from the 2006-2010 National Survey of Family Growth (NSFG), conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The 2006-2010 NSFG included in-person interviews with 12,279 women aged 15-44. Some data in the trend analyses are taken from NSFG surveys conducted in 1982, 1988, 1995, and 2002.

  • About 37% of births in the United States were unintended at the time of conception.
  • The overall proportion unintended has not declined significantly since 1982.
  • The proportion unintended did decline significantly between 1982 and 2006-2010 among births to married, non-Hispanic white women.
  • Large differences exist between groups in the percentage of births that are unintended. For example, unmarried women, black women, and women with less education or income are still much more likely to experience unintended births compared with married, white, college-educated, and high-income women.

Congenital Abnormalities

PRAMS is the cronym for the Pregnancy Risk Assessment Monitoring System, is a surveillance project of the United States Centers for Disease Control and Prevention (CDC) and state health departments. PRAMS collects state-specific, population-based data on maternal attitudes and experiences before, during, and shortly after pregnancy.


Estimated annual number of United States children with long-term sequelae caused by various disease conditions.[5]

  • Congenital cytomegalovirus data are from a literature review, with varying collection periods spanning multiple years.
  • Down syndrome data are from the National Birth Defects Prevention Network, 1999-2001.
  • Fetal alcohol syndrome data are from a literature review of studies from the 1980s and 1990s.
  • Spina bifida/anencephaly data are from 23 population based surveillance systems from 1999-2000.
  • Pediatric HIV/AIDS data are from the HIV/AIDS Surveillance Report, 2001.
  • Haemophilus influenza b data are from the National Notifiable Disease Surveillance Report, 2002.
CDC Congenital abnormality graph.jpg

Assumes 4 million live births per year and 20 million children less than 5 years of age. Where applicable, numbers represent means of published estimates. All estimates should be considered useful for rough comparisons only since surveillance methodology, time periods, and diagnostic accuracy varied by study.
