United States Births
| Update on Zika Virus-Associated Birth Defects and Evaluation of All U.S. Infants with Congenital Zika Virus Exposure - U.S. Zika Pregnancy Registry, 2016
"During the analysis period, 1,297 pregnant women in 44 states were reported to the USZPR. Zika virus-associated birth defects were reported for 51 (5%) of the 972 fetuses/infants from completed pregnancies with laboratory evidence of possible recent Zika virus infection (95% confidence interval [CI] = 4%-7%); the proportion was higher when restricted to pregnancies with laboratory-confirmed Zika virus infection (24/250 completed pregnancies [10%, 95% CI = 7%-14%]). Birth defects were reported in 15% (95% CI = 8%-26%) of fetuses/infants of completed pregnancies with confirmed Zika virus infection in the first trimester. Among 895 liveborn infants from pregnancies with possible recent Zika virus infection, postnatal neuroimaging was reported for 221 (25%), and Zika virus testing of at least one infant specimen was reported for 585 (65%). Conclusions And Implications For Public Health Practice: These findings highlight why pregnant women should avoid Zika virus exposure. Because the full clinical spectrum of congenital Zika virus infection is not yet known, all infants born to women with laboratory evidence of possible recent Zika virus infection during pregnancy should receive postnatal neuroimaging and Zika virus testing in addition to a comprehensive newborn physical exam and hearing screen. Identification and follow-up care of infants born to women with laboratory evidence of possible recent Zika virus infection during pregnancy and infants with possible congenital Zika virus infection can ensure that appropriate clinical services are available."

- The 2014 preliminary number of U.S. births was 3,985,924 an increase of 1% from 2013 (Data are based on 99.71% of 2014 births).
- Births Resulting From Assisted Reproductive Technology: Comparing Birth Certificate and National ART Surveillance System Data, 2011. "This report compares data on births resulting from assisted reproductive technology (ART) procedures from 2011 birth certificates with data from the 2011 National ART Surveillance System (NASS) among the subset of jurisdictions that adopted the 2003 revised birth certificate as of January 1, 2011, with information on ART. Births resulting from ART procedures appear to be underreported on the birth certificate; however, the magnitude of underreporting varied by jurisdiction and maternal-infant health characteristics." Assisted Reproductive Technology
- Congenital anomalies identified at birth among infants born following assisted reproductive technology in Colorado "This study suggests that conception by means of ART is not associated with an increased risk of congenital abnormalities identified by birth certificate data in Colorado when compared with births following natural conception."
- Prevalence Estimates of Gestational Diabetes Mellitus in the United States, Pregnancy Risk Assessment Monitoring System (PRAMS), 2007-2010 "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 "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

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". 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.

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.
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.

Map shows state by state trend changes in pertussis notifications for 2014.
Pertussis (whooping cough, 100-day cough) is a highly contagious bacterial (Bordetella pertussis) infection prevented by vaccination with the pertussis vaccine. Symptoms are initially similar to the common cold. Neonatal infection can be fatal, with 1% of infected infants under one year of age dying, other complications include: pneumonia (lung infection), convulsions (violent, uncontrolled shaking), apnea (slowed or stopped breathing) and encephalopathy (disease of the brain).
