Updated Birth Defects Data and State Profiles

The state-level data on birth defects from the National Birth Defects Prevention Network (NBDPN) has been updated to the most current data available. The NBDPN, in collaboration with the Centers for Disease Control and Prevention (CDC), collects and reports data on major birth defects from state birth defects surveillance systems. Birth defects are generally referred to as abnormalities of structure, function or metabolism (body chemistry) present at birth that result in physical or mental disabilities, or death.

Through a cooperative agreement with the CDC, NBDPN birth defects data for 2010-2014 are available on PeriStats. Data from 40 states are presented including the newly added states of Indiana and Alaska. Prevalence rates for 50 conditions are displayed and are provided by maternal race/ethnicity. Chromosomal defects (Trisomy 13, 18 and 21) and gastroschisis are also provided stratified by maternal age, a known risk factor for these defects. Most prevalence rates are reported as a prevalence per 10,000 live births.

March of Dimes and CDC have coordinated with NBDPN to provide State Birth Defect Profiles, which describe in impact of birth defects in each state and the importance of birth defects monitoring to understanding and addressing the needs of families affected. The state profiles can be used by policy makers and non-research professionals in framing the issues around birth defects surveillance for each state. This new resource can be found on the right hand side of Peristats website under State Summaries (Select: Birth Defects Profile).

Poverty Data Update

PeriStats has been updated with data on the proportion of women and children living in poverty for each state, the District of Columbia, and the U.S. during 2013-2015. The updated data are from The Current Population Survey (CPS) which is sponsored by the U.S. Census Bureau and the U.S. Bureau of Labor Statistics (BLS). The data were retrieved from IPUMS.org, Minnesota Population Center at the University of Minnesota.

Poverty is defined as those who make less than 100% of the poverty threshold established by the US Census Bureau. The poverty threshold for a family of three was $18,552 in 2013, $18,850 in 2014 and $18,871 in 2015. Data are available for the percent of women (15-44 years) and percent of children (18 years and younger) living in poverty.

These data are available under the "Population" topic accessible from the selection tool on the left hand side of PeriStats.

          Updated Data and PeriStats Enhancements

          Updated data on births

          PeriStats has been updated with 2014 natality data from the National Center for Health Statistic (NCHS), as compiled from birth certificate data provided by the 57 vital statistics jurisdictions through the Vital Statistics Cooperative Program.

          The topics updated include

          • Births
          • Preterm Birth
          • Birthweight
          • Prenatal Care
          • Singletons and Multiples
          • Delivery Method

          This data update includes a change in the gestational age data shown on PeriStats. Beginning with the 2014 natality data, NCHS switched the primary measure of gestational age from last menstrual period (LMP) to obstetric estimate (OE). Preterm birth rates, very preterm birth rates, and other percentages of births by gestational age calculated using OE are not comparable to LMP data, and therefore PeriStats will only be showing OE data beginning with this data update. Because of this switch in measurement, the March of Dimes reset its preterm birth goal for 2020 to 8.1%. These data are presented on PeriStats for the first time. More information on the transition to OE data and trend data by state back to 2007 are available from NCHS. View our preterm birth calculations page for more information.

          Enhancements

          We are pleased to announce enhancements have been made to PeriStats to improve the user experience.

          • Upgraded mapping and charting software now provides an expanded interactive experience for the user. New charts and maps allow the user to hover and view the rates and category names or geographic tags.
          • A new map type has been added for preterm birth, showing each county's preterm birth rate in comparison to the March of Dimes 2020 goal of 8.1%. Counties in purple have met or exceeded the MOD 2020 goal, and red counties are those with the highest rates of preterm birth in the state.
          • An updated PowerPoint slide template allows users to download charts and maps and seamlessly integrate them into their own presentations.

          Expanded PRAMS Data Now Available

          In collaboration with the Centers for Disease Control and Prevention’s (CDC) Division of Reproductive Health, the March of Dimes has expanded the number of Pregnancy Risk Assessment Monitoring System (PRAMS) indicators available on PeriStats.

          The 13 new indicators largely encompass preconception and interconception care and include data on pregnancy intention and contraception use at time of conception, pre-pregnancy morbidities like diabetes and hypertension, and postpartum contraception use, checkups, and depressive symptoms, among others.

          Data for the new indicators are available for 2000-2011, depending on the state, and are available stratified by maternal race/ethnicity and age, household income, and Medicaid status.

          PRAMS is a system of state and population based surveys that routinely collect information about maternal behaviors and experiences before, during, and shortly after pregnancy. Participating PRAMS states survey a sample of women who have had a recent live birth and link survey responses to medical information collected on birth certificates to produce statewide estimates of maternal health indicators. To find out more information about PRAMS in your state, click on the link for the PRAMS website on each PeriStats state summary page.

          MMWR Article About Tdap Vaccine Coverage

          May 26, 2015 A recent article published by the Centers for Disease Control and Prevention (CDC) describes Tdap vaccine coverage among women who were recently pregnant. The authors of the article, published in the May 22nd edition of Morbidity and Mortality Weekly, analyzed data from the Pregnancy Risk Assessment Monitoring System (PRAMS) data in 16 states and New York City (NYC).

          The Tdap vaccine provides protection from three diseases: tetanus, diphtheria and pertussis. The protection offered by this vaccine against pertussis is particularly important for newborns, who are most vulnerable to the highly contagious disease. The number of cases of pertussis has been increasing since the 1980s. In 2012, more than 48,000 cases were reported. When a woman is vaccinated with the Tdap vaccine during pregnancy (in the 3rd trimester) she passes on her immunity to her baby before birth.

          The CDC study estimates that in 2011, 55.7% of women in the US received the Tdap vaccine before, during, or after their most recent pregnancy. This percentage varied widely across states from 38.2% in NYC to 76.6% in Nebraska. Women who started prenatal care earlier were more likely to report they received the vaccine. Among women who reported being vaccinated most reported receiving the vaccine after delivery.

          The article is available on the CDC website or by clicking here.

          PeriStats has data by maternal race/ethnicity and maternal age for 17 pregnancy related topics from PRAMS. For additional PRAMS data and Tdap coverage in your state go to the CDC PRAMStat website.

          Special Care Nursery Admissions

          WHITE PLAINS, N.Y., Oct. 19, 2011- The March of Dimes Perinatal Data Center has partnered with the National Perinatal Information Center/Quality Analytic Services (NPIC/QAS) to describe special care nursery admissions among NPIC/QAS member hospitals.

          Specialty care was defined as any time spent by the infant in a neonatal intermediate care unit (NINT, Level II nursery) or a neonatal intensive care unit (NICU, Level III nursery) bed at any time during the hospital stay. Key findings from the analyses included:

          • 14.4% of newborns delivered at or transferred to NPIC/QAS member hospitals were admitted to a special care nursery.
          • Among all special care nursery admissions, 49.1% were preterm, 50.4% were term (37-41 weeks) and less than 1% were post-term.
          • The average length of the hospital stay for newborns admitted to a special care nursery was 13.2 days, with an average hospital charge of $76,000.
