What is the prevalence of Spina bifida?

Spina bifida is a complex neural tube defect with a global prevalence estimated at approximately 1 in 1,000 live births, though rates vary significantly by region and ethnicity. While often classified as a common birth defect rather than a rare disease in many parts of the world, its long-term management requires lifelong specialized care for patients ranging from infancy through adulthood.

What is the global prevalence and incidence of Spina bifida?

Estimating the exact number of people living with Spina bifida is challenging due to variations in healthcare reporting and the spectrum of disease severity, ranging from spina bifida occulta to myelomeningocele. According to the CDC and NIH GARD, the incidence of Spina bifida in the United States is approximately 1,400 to 1,500 births per year. Because it is a lifelong condition, the total prevalence includes both new pediatric cases and the growing population of adults managing the condition's long-term impacts.

Are there geographic or demographic differences in Spina bifida?

Research indicates that Spina bifida prevalence is influenced by both genetic and environmental factors, including maternal folic acid intake. Certain populations, particularly those of Hispanic descent, historically show higher rates of neural tube defects. Furthermore, the condition affects both males and females, though some clinical studies suggest a slightly higher prevalence among females.

What are the challenges in tracking Spina bifida statistics?

Accurate data collection for Spina bifida is often hindered by the following factors:

• Variability in Severity: Mild forms (spina bifida occulta) may be asymptomatic and never formally diagnosed.


• Reporting Discrepancies: Data collection methods vary between countries and state registries.


• Underdiagnosis: In some regions, access to prenatal screening is limited, leading to gaps in birth defect surveillance.

How does the DiseaseMaps community reflect these statistics?

While global statistics provide a broad overview, the Spina bifida community at DiseaseMaps.org offers a unique, real-world perspective. Currently, 207 people with Spina bifida have joined our community to share their lived experiences, underscoring that behind every statistical figure is a person navigating the challenges of this condition, from neurosurgical needs to executive function support.

Next steps

• Consult with a multidisciplinary team including a urologist, neurosurgeon, and orthopedist for comprehensive care.


• Connect with the 207 members of the Spina bifida community at DiseaseMaps.org to share resources and support.


• Stay informed on the latest clinical research through the Spina Bifida Association or NIH GARD.
