Multiple Birth Defects in the Same Child

Analyses of birth defects surveillance data is based on cases. An infant or fetus can have multiple birth defects and can be counted as a separate case for each defect. Thus, an infant/fetus with anencephaly and cleft lip is counted as a case of anencephaly, and again as a case of cleft lip. When using this approach, it is important to recognize that the number of different cases cannot then be added to reach a total number of infants/fetuses.

When an infant/fetus has two or more conditions coded in the same category in an analysis, it is only counted once. For example, if an infant has atrial septal defect and ventricular septal defect. The infant is counted once in tabulations for atrial septal defect, and once in tabulations for ventricular septal defect. Additionally, the infant only is only counted once in tabulations for cardiac defects.


Rates show how often an event occurs in a group of people during a period of time. The group used when calculating rates birth defects is the total number of conceptions.

Incidence rates show the number of new cases of a condition. Prevalence rates show number of existing cases of a condition. Since the number of conceptions is unknown, as is the number of cases that cannot be counted due to spontaneous abortions, incidence cannot be calculated. Because of this, prevalence rates are calculated to show the occurrence of birth defects.

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

(the number of cases with birth defect A in an area and time period / the number of live births in that area and time period) x Standard # of live births*

*Typically, the standard number of live births used is 1,000 or 10,000 depending on the size of the population.
