Like languages, facial features have been linked to ethnicities. Basically, nasal index is ratio of nasal breadth to nasal length, which varies greatly among different anthropometric groups and climate regions. Aim: to investigate sexual dimorphic characterization in nasal parameters of the Ikwo population in South-east, Nigeria.
The study recruited 250 Ikwo samples (males = 130, females = 120), after ethical approval gotten from University Research Committee and informed consents signed by the participants. Nasal length, width and indices were measured.
Age and nasal indices appeared positively correlated but with weak R 2 Adjusted value (Age = 146 + 1.91 × Nasal indices, 35%). Also, sex and nasal indices were positive and very strong adjusted level (NI = 61+0.24 × Male and 61 + 0.084 × Female, and 82%).
The mean nasal indices for both sexes in Ikwo population belong to platyrrhine nose classification, with predictive power that can be helpful in forensic science, craniofacial surgery, neurosurgery and developmental biology.
探究尼日利亚东南部伊克伍人群的鼻部参数的性别二态性特征。
本研究招募了 250 名伊克伍样本（男性=130，女性=120），在获得大学研究委员会的伦理批准和参与者签署的知情同意书后进行。测量了鼻长、鼻宽和鼻指数。
年龄和鼻指数呈正相关，但调整后的 R 2 值较弱（年龄=146+1.91×鼻指数，35%）。此外，性别和鼻指数呈正相关，且调整后的相关性非常强（NI=61+0.24×男性和 61+0.084×女性，82%）。
伊克伍人群中男女的平均鼻指数属于扁鼻类分类，具有预测能力，有助于法医学、颅面外科、神经外科和发育生物学。
