Introduction: Anatomy of the human body and its measurements are affected by biological, ecological, age and sex factors. Anthropometric measurements determine the morphological characteristics of the face and head.Aim: To assess age-specific sex differences in weight, height and cephalofacial dimensions among Igbo tribe in Nigeria. Materials and methods:This research is conducted on 300 subjects, 150 males and 150 females in the age of 15-18 years. In addition to the height and weight of the subjects, cephalofacial parameters were measured and then cephalic and facial index is calculated. The cranial and prosopic indices were sharply higher in age 17 years for both sexes at level P<0.005. The weight of males was slightly higher than females at 18 years and above (P<0.005). Conclusion:There were predominantly mesoprosopic and mesocephalic face and head forms in both sexes.
