Demographic Trends and Gender Preferences

The study involved 400 subjects, 200 each of the two ethnic groups(100 males and 100 females).The age range was 18-35years.Subjects with facial deformities or surgeries that involved the nasal region were excluded from the study.Subjects that have both parents and grandparents of each ethnic group and who have lived in that environment for at least the first 18years of their lifetime were selected for the study.The nasal length and width were measured using spreading calipers and nasal indices deducted from these measurements.Test for significance was done using the students' t-test.Results showed the nasal indices of the Ibibio males and females to be 86.58±1.20 and 81.75±1.14respectively and for the Yakurr males and females, it was 77.76±0.82 and 102.27±1.13respectively.There was significant ethnic and gender differences in all the nasal parameters (nasal length, nasal width and nasal indices) at p<0.05.From the nasal indices the nose type of the Ibibio males is platyrrhine while that of the Ibibio females is mesorrhine, the Yakurr males also have mesorrhine nose type while the Yakurr females have platyrrhine nose type.With this result, nasal parameters could be a useful tool in gender and ethnic differentiation between the Ibibio and Yakurr ethnic groups.
