Which group is more commonly affected by cleft lip and palate?

The group that is more commonly affected by cleft lip and palate is Native Americans. This condition tends to show varying prevalence rates among different ethnic groups, with research indicating that Native American populations exhibit higher incidence rates compared to other groups. Factors contributing to these disparities can include genetic predispositions, environmental influences, and variations in maternal health and nutrition.

In contrast, while cleft lip and palate do occur across all ethnicities, the prevalence rates among European Americans, African Americans, and Latino Americans are generally lower than those found in Native American communities. Understanding these epidemiological differences is crucial for public health strategies, early intervention programs, and targeted support for affected populations.
