Overall Rates

Rates for selected birth defects

Diaphragmatic Hernia: 43% of babies with posterolateral diaphragmatic defects have other structural defects; heart defects occur in 26% of these infants. Only 29% of those with additional birth defects survive to age 1; whereas 55% of liveborn babies with isolated diaphragmatic hernia are alive at 1 year.

Neural Tube Defects: Hispanics have 50% higher risk for all NTD subtypes than Whites. Parents' ages do not affect risks, but anencephaly is more common in babies born to women who have previously given birth.

Teen Mothers: Compared to mothers 25-29, teen mothers have an 11% higher birth defects risk. Teens are at higher risk for birth defects involving nearly every organ system but major heart defects.
