Multiple Birth Defects in the Same Child

An infant or fetus can have multiple birth defects. For example, an infant/fetus with a cleft lip and spina bifida is counted when cleft lip is queried and is counted when spina bifida is queried. Therefore the total of the two queries cannot be added to reach a total number of infant/fetuses.

Birth Prevalence (expressed as cases of a birth defect of interest per a standard number of live births)

Ideally, incidence rates would be used instead of prevalence to measure birth defect occurrence. Since the number of conceptions is unknown, as is the number of cases “lost” through spontaneous abortions, technically speaking we cannot determine incidence. Because of this, most individuals working in the area of birth defects use the term ‘birth prevalence’ to refer to birth defect occurrence.

The formula for birth prevalence (expressed as cases of a defect of interest per 10,000 live births):
The number of infants with the birth defect of interest in an area and time period / by the number of live births in that area and time period * 10,000

EXAMPLE: 62 cases of hypoplastic left heart syndrome statewide delivered in 2009-2013 / 266,073 live births in 2009-2013 = 2.33 cases per 10,000 live births
