NCBDDD History

Activities of The National Center on Birth Defects and Developmental Disabilities (NCBDDD) have a long history that spans from 1946 with the establishment of CDC to the present. As NCBDDD begins its second decade as a national Center, we have provided an in-depth reflection of what we have accomplished through the years through a timeline of milestones.

NCBDDD Timeline


Picture of CDC building in 1946
  • The Communicable Disease Center (CDC) is established in Atlanta (the precursor of the current Centers for Disease Control and Prevention). CDC’s goal is to protect the public by quickly identifying diseases brought into the United States by soldiers returning from out of the country.


  • CDC expands its reach into chronic disease with investigation of a cancer cluster in Niles, Illinois. Because of the connection between cancer and birth defects, CDC begins to explore birth defects research issues.


  • After the thalidomide tragedy in Europe, the Metropolitan Atlanta Congenital Defects Program (MACDP)–the first population-based birth defects surveillance system in the United States―is born through the collaborative efforts of CDC, the Georgia Mental Health Institute, and the Emory University School of Medicine.


  • President Richard M. Nixon signs the National Sickle Cell Anemia Control Act providing for the establishment of voluntary sickle cell screening and counseling programs.


hospital records
  • CDC begins the national Birth Defects Monitoring Program with grants from the National Institute for Child Health and Human Development and the March of Dimes Birth Defects Foundation, using hospital discharge records of newborns from about 800 hospitals around the nation.  
  • The International Clearinghouse for Birth Defects Monitoring Systems is established with financial support from the March of Dimes and technical support from CDC.


group of people all ages
  • Congress passes the Individuals with Disabilities Education Act (IDEA), mandating that all children with disabilities receive a free, public education, regardless of the level of severity of their disability. 
  • Congress mandates establishment of a network of federally supported hemophilia treatment centers in the United States to provide comprehensive care for people with bleeding disorders.


baby drinking from a baby bottle
  • CDC sends an Epidemic Intelligence Service officer to investigate a cluster of infant deaths, which subsequently is linked to chloride-deficient infant formula. This investigation leads swiftly to public health action for regulation of infant formula ingredients, culminating with the Infant Formula Act of 1980.


red ribbon
  • January is declared Birth Defects Prevention Month. Tragically, during the period 1981 through 1984, many hemophilia patients transfused with clotting factor in the United States become infected with HIV and eventually die of AIDS. Many also are infected with the yet-to-be-identified hepatitis C virus, which results in chronic liver disease.


pill bottles
  • Researchers in France find that valproic acid, a drug used to treat epilepsy, causes spina bifida. It is the first teratogen discovered by a birth defect surveillance system. CDC quickly works with the U.S. Food and Drug Administration (FDA) to re-label the drug to warn women and their health care providers about this serious risk.


sickle cells
  • President Ronald W. Reagan designates September as National Sickle Cell Awareness Month. CDC receives funding for HIV risk reduction services for people with hemophilia and others using blood products.


  • CDC confirms that the acne medication isotretinoin (Accutane®) is linked with serious birth defects. 
  • CDC and the Georgia Department of Human Resources initiate the Metropolitan Atlanta Developmental Disabilities Study (MADDS) to provide population-based prevalence data on developmental disabilities. 
  • A CDC study supported by Congress and funded by the then-U.S. Veterans Administration (currently the U.S. Department of Veterans Affairs) shows that Vietnam veterans are at no higher risk than other men for fathering babies with birth defects, and produces the first of many publications on risk factors for birth defects.


  • Heat-treated, blood-based clotting factor products used by people with hemophilia are introduced and shown to eliminate the transmission of HIV through infusion of clotting factor products.


toxic waste
  • CDC establishes cooperative agreements with seven states to track the occurrence of birth defects and low birth weight potentially related to toxic waste exposure. 
  • The National Council on Disability publishes a report on addressing the needs of people with disabilities in the United States. As 1 of 10 top priorities, the council identifies the creation of a program to address public health needs and the effects of people with disabilities on society, as well as the effects of society on people with disabilities.

  • Congress appropriates $3.8 million to CDC to provide technical assistance and short-term financial support for states and communities to establish programs for the prevention of disabilities. 
  • A disabilities prevention program is created within the CDC National Center for Environmental Health. 
  • CDC funds the first three disabilities prevention program research projects, all focusing on determining the prevalence of secondary conditions. 
  • A CDC study shows that periconceptional use of a multivitamin containing folic acid is associated with a reduced risk for neural tube defects (NTDs).


cut-out of heart
  • CDC publishes a report that identifies birth defects as a leading cause of infant mortality. This report also notes that heart defects account for 38% of birth defects-related infant mortality.

  • A group of individuals involved in birth defects surveillance meets and begins to develop the National Birth Defects Prevention Network(NBDPN), an incorporated organization with participants from all 50 states. 
  • The Interagency Coordinating Committee on Fetal Alcohol Syndrome is created to coordinate federal FAS activities in response to a recommendation of an expert committee of the Institute of Medicine. 
  • CDC holds a national workshop on the benefits and risks of screening newborns for cystic fibrosis, leading to recommendations for public health policies for such screening. 
  • CDC convenes a group of organizations that becomes the National Council on Folic Acid (NCFA), dedicated to advocacy and education about folic acid-preventable birth defects. 
  • CDC begins Early Hearing Detection and Intervention activities as part of a national effort to promote the early detection of hearing loss, tracking of infants and children who have hearing loss, and initiation of effective intervention systems. This results in funding for programs in fiscal year 2000. 
  • CDC and the NBDPN publish the first annual Congenital Malformations Surveillance Report, with data on 47 categories of birth defects from 21 states. This is the first time population-based birth defects surveillance data from a number of states are presented together. NBDPN functions as a national clearinghouse on birth defects information. 
  • CDC partners with three universities to develop and test Project CHOICES (Changing High-Risk Alcohol Use and Increasing Contraception Effectiveness Study), a motivational intervention aimed at preventing alcohol-exposed pregnancies. Study results show that a brief motivational intervention can reduce the risk of an alcohol-exposed pregnancy. Project CHOICES becomes a model program embraced by researchers and used in other federal initiatives.

  • The Fetal Alcohol Syndrome Surveillance Network is created in October and develops a multisource surveillance methodology to determine the prevalence of FAS within certain regions of the United States. 
  • A citizen’s group in Brick Township, New Jersey, contacts the New Jersey Department of Health and Senior Services about what seems to be a larger-than-expected number of children with autism in Brick Township. CDC and the Agency for Toxic Substances and Disease Registry work together to find out how common autism is in Brick Township and to study the possible relationship of environmental factors to autism in the community. At this time, the prevalence of ASDs in the United States is 6.7 per 1,000 children. The prevalence of autism in Brick Township seems to be higher than that in other studies, particularly other studies conducted in the United States, but within the range of a few recent studies among smaller populations that used more thorough case-finding methods.

  • CDC begins collaborating with approximately 140 federally funded hemophilia treatment centers in the United States and its territories through the Universal Data Collection (UDC) Program to monitor blood product safety and outcomes of care for people with bleeding disorders. 
  • The FDA approves hydroxyurea. It becomes the first drug proven to prevent complications of SCD. 
  • President William J. Clinton signs into law the Rehabilitation Act Amendments of 1998. These amendments provide details on access to federally funded programs and services. The law strengthens section 508 of the Rehabilitation Act of 1973 and requires access to electronic and information technology provided by the federal government. The law applies to all federal agencies when they develop, acquire, maintain, or use electronic and information technology. Federal agencies must ensure that this technology is accessible to employees and members of the public with disabilities to the extent it does not pose an "undue burden".

The study finds that children with an implant are 30 times more likely to get a type of bacterial meningitis than are children of the same age among the general population. The studies also find that children with an implant with a positioner (used with some implant models) are more likely to get meningitis than children who have an implant without the positioner. The implant model with a positioner voluntarily is removed from the market by the manufacturer in July 2002. Vaccination recommendations are changed to include cochlear implant recipients in the high-risk group for bacterial meningitis. 
  • NCBDDD convenes its first national conference.

Amazing Me also encourages the parent-reader to look for milestones in their own child, provides parents a tool to track their child’s development, and encourages parents to talk with their child’s doctor about their child’s development.
  • In 2012, NCBDDD publishes Alcohol use and binge drinking among women of childbearing age – United States, 2006-2010 in CDC’s Morbidity and Mortality Weekly Report (MMWR). The report describes findings from CDC’s Behavioral Risk Factor Surveillance System (BRFSS) examining any alcohol use and binge drinking among pregnant and nonpregnant women of childbearing age (18-44 years) in the U.S. from 2006 to 2010. Findings from these data include that 7.6% of pregnant women (or 1 in 13) and 51.5% of nonpregnant women (or 1 in 2) reported drinking alcohol in the past 30 days.
  • NCBDDD received funding to enhance and expand public health tracking of congenital heart defects (CHD) across the lifespan. With this new funding, CDC is working on a project with the New York State Department of Health, Emory University in Atlanta, Georgia, and the Massachusetts Department of Public Health to develop population-based tracking of adolescents and adults with CHD. These tracking activities will help us better understand the survival, healthcare use, and long term outcomes of adolescents and adults affected by CHD. Understanding health issues and needs across the lifespan is vital to improving the lives of individuals born with these conditions.
  • NCBDDD conducted the first study to look at the costs and health outcomes (cost-effectiveness) of newborn screening for early identification of children with a critical congenital heart defect (CCHD). This information is helpful for state officials considering adding this condition to their existing newborn screening programs.

  • CDC Public Health Grand Rounds:  Preventing Venous Thromboembolism. 
  •  NCBDDD publishes Prevalence of cerebral palsy, co-occurring autism spectrum disorders, and motor functioning – Autism and Developmental Disabilities Monitoring Network, USA, 2008. Findings indicate that about 1 in 323 children in multiple communities in the United States has been identified with cerebral palsy. 
  • NCBDDD collaborates with NCCDPHP in the publication of a CDC Vital Signs report on binge drinking among women and girls. The report finds that binge drinking is a serious, under-recognized problem among women and high school girls. Some of the key findings include that 1 in 8 adult women and 1 in 5 high school girls binge drink. Binge drinking increases a woman’s chance of breast cancer, heart disease, sexually transmitted diseases, unintended pregnancy, and many other health problems. Drinking during pregnancy can lead to miscarriage, sudden infant death syndrome (SIDS) and fetal alcohol spectrum disorders (FASDs).  
  • NCBDDD launches Birth Defects COUNT, a global initiative to reduce death and lifelong disability due to neural tube defects. Worldwide, more than 300,000 neural tube defects occur each year. Birth Defects COUNT aims to increase folic acid intake among women of reproductive age through fortification and other means. These efforts can help prevent the majority of neural tube defects globally each year. The initiative is supported by three main goals: improve the science base (surveillance, epidemiology, laboratory and prevention capacity) to support prevention efforts; educate and inform on the benefits of fortification policies and other interventions; and enhance strategic partnerships and communication to support prevention strategies. Currently, we are only preventing about 10% of neural tube defects globally through folic acid fortification. The initiative aims to reduce infant and child disability and death resulting from neural tube defects. Birth Defects COUNT will continue to engage key partners in these efforts.  
  • NCBDDD met with partners from other federal agencies, public and private organizations and the public to collaborate on the Treating for Two Initiative: Safer Medication Use in Pregnancy.  February 2013 – NCBDDD sent Epidemic Intelligence Service (EIS) officers to investigate a birth defects cluster in Washington State. From January 2010 to January 2013, a three-county area of central Washington had four times as many pregnancies affected by anencephaly than were expected based on the most recent U.S. estimates. To look for potential causes, researchers compared women who had a pregnancy affected by anencephaly and those who did not have a pregnancy affected by a birth defect. Researchers did not find differences between the groups. 
  • September 2013 – The Birth Defects Study To Evaluate Pregnancy exposureS (BD-STEPS) is publicly announced. BD-STEPS builds upon the foundation of birth defects research from the National Birth Defects Prevention Study (NBDPS). This new study further examines findings from the NBDPS and follows up on leads to understand more about what causes birth defects and how to prevent them. CDC coordinates the Centers for Birth Defects Research and Prevention (CBDRP) to collaborate on BD-STEPS. Participating sites are located in Arkansas, California, Georgia (CDC), Iowa, Massachusetts, New York, and North Carolina.

  • Began the next generation of birth defects prevention research with BD-STEPS.
  • Collaborated with federal and external partners to develop a national strategy to improve the health of mothers and babies through better research, reliable guidance, and informed decisions related to safer medication use in pregnancy. Launched a new Treating for Two website.
  • Shared new prevalence estimates from the Autism and Developmental Disabilities Monitoring (ADDM) Network indicating that about 1 in 68 eight-year-old children living in multiple communities in 2010 were identified with autism spectrum disorder.
  • Launched a “Webinar Series on Bleeding and Clotting Disorders” to provide evidence-based information on new research, interventions, emerging issues of interest in blood disorders, as well as innovative approaches in collaborations and partnerships.
  • Launched a website on Vitamin K Deficiency Bleeding.
  • Launched a nationwide report on adults with disabilities and physical activity. CDC’s Vital Signs™ : “Adults with Disabilities – Physical Activity is for Everybody” presented data showing that 1 in 2 adults (18-64 years of age) with a disability get no aerobic physical activity and that people with disabilities who had a recommendation from a doctor or health professional were more likely to be physically active.
  • Published an important scientific article, which documented for the first time that adults with specific types of disabilities are more likely to have measured high blood pressure compared with adults without disabilities.
