Cleft lip and/or palate
is a congenital abnormality that is seen frequently around the world. On average, about 1 in every 500-750 live births result in a cleft (Hardin-Jones, Karnell, & Peterson-Falzone, 2001). Furthermore, in the U.S., the prevalence
for cleft lip with or without cleft palate (CL +/- P) is 2.2 to 11.7 per 10,000 births. Cleft palate alone (CP) results in a prevalence rate of 5.5 to 6.6 per 10,000 births (Forrester & Merz, 2004). Cleft of the lip, palate, or both is one of the most common congenital abnormalities and has a birth prevalence rate ranging from 1/1000 to 2.69/1000 amongst different parts of the world (McLeod, Saeed, & Arana- Urioste, 2004).
Africans and African Americans
A look in to the prevalence rates of different cultures in the U.S. when compared to country of origin begins with Africans
and African Americans
. One per 2500 African Americans are born with a cleft (Suleiman, Hamzah, Abusalab, & Samaan, 2005). African Americans have a lower prevalence rate of CL +/- P when compared to Caucasians. A prevalence rate of 0.61 per 1,000 and 1.05 per 1,000 live births respectively was reported by Croen, Shaw, Wasserman and Tolarova (1998). In Malawi
there is a reported low prevalence rate for cleft lip and/or palate, 0.7 per 1,000 live births (Chisi, Igbibi, & Msamati, 2000). Suleiman et al. (2005) found that the prevalence rate of clefting among a group of Sudanese hospital new-borns in the city of Khartoum is 0.9 per 1,000... Read More
