Anthropological characteristics of young Nigerian adults

Abstract

Anthropological analyses of Nigerian adult in the age bracket 25-30 years were conducted. The
investigation considered height, weight, waist circumference, auricular morphology and carrying angle in both sexes.
The aim was to characterize these parameters and establish any correlation among them.
Eight hundred and twenty subjects were considered. These comprised 420 males and 400 females. Average values
of 174 ± 0.1 cm, 64.0 ± 0.2 kg, 31.0 ± 0.1 cm and 169 ± 2.67o for height, weight, waist circumference and carrying
angle respectively, were recorded for males. Means values of 165 ± 0.2 cm, 55.0 ± 0.1 kg, 30.0 ± 0.1 cm and 164 ±
4.00o respectively were obtained for females. Statistical analysis for correlation coefficient, showed no correlation
among the parameters taken, for males. However, some degree of correlation existed for females, indicating that
height, weight and waist size may have some bearing on carrying angle.
Gross examination of the auricle showed that 42% of the males had free lobules, compared to 47% in females.
Attached lobules occurred in 58% and 53% of males and females respectively, while depressed and protruded
antihelices were presented in 8% and 92% of males respectively and 12% and 88% respectively of females. The
palpebral line corresponded to the apex of helix in 69% of males and 76% of females. The remainder either lies a little
above or below this line.
We therefore conclude that Nigerian males have higher percentages of attached lobules, protruded antihelix and
curved helix compared to the females. Conversely, more females have helical apices located in line with the palperal
fissure. The auricular features reported for females probably help to enhance their feminine and cosmetic values
