In which patient population are umbilical hernias most commonly found?

Umbilical hernias are most commonly found in full-term African American infants, primarily due to a combination of anatomical and demographic factors. In this population, the incidence of umbilical hernias is higher compared to other ethnic groups. This can be attributed to variations in the strength of the abdominal wall and genetic predispositions that may contribute to the likelihood of hernia formation.

While umbilical hernias can occur in newborns of all ethnicities, the distinctive prevalence in full-term African American infants makes this group particularly noteworthy. Premature infants also have a higher risk of complications due to their underdeveloped tissues; however, they are not the most commonly associated group for umbilical hernias when considering overall incidence. Adults over 50 may experience hernias due to factors like age-related tissue weakness or obesity, but the question specifically pertains to a pediatric population where the highest rates have been observed in full-term African American infants. This context solidifies the selection of the correct answer regarding the typical demographics most affected by umbilical hernias.
