Umbilical hernias are most common in infants — especially premature babies and those with low birth weights. Black infants appear to have a slightly increased risk of umbilical hernias. The condition affects boys and girls equally.

For adults, being overweight or having multiple pregnancies may increase the risk of developing an umbilical hernia. This type of hernia tends to be more common in women in their 50s or 60s.
