This is untrue. Children are more likely to have recessive traits expressed, which may include health defects, but they are not likely to have them. It takes generations of inbreeding for such traits to express themselves regularly. The Habsburgs didn't go to pot all at once. Frankly, improper nourishment during pregnancy is far more likely to result in birth defects than incest, and we don't require women to take folic acid supplements, etc.

Results of inbreeding
Inbreeding may result in a far higher phenotypic expression of deleterious recessive genes within a population than would normally be expected.[1] As a result, first-generation inbred individuals are more likely to show physical and health defects, including:
* reduced fertility both in litter size and sperm viability
* increased genetic disorders
* fluctuating facial asymmetry
* lower birth rate
* higher infant mortality
* slower growth rate
* smaller adult size
* loss of immune system function.
