Pattern of Brain body Index in three West African populations

Emmanuel Igho Odokuma, Gerald Ikechukwu Eze, Augustine Egbagba.


AIM: The usefulness of brain weight in facilitating proper identification of and in emphasizing a common origin of studied populations is far reaching.
METHOD: This study involved 699 (male 361; female 338) volunteers whose age ranged 18 years and over. Respondents were selected along three ethnic groups including Urhobo (male 156; female 147), Ibo (male 141 female 145) and Edo (male 64; female 46) and it was ensured that population for the study was collected using a random stratified method.
RESULTS: Measurement of Brain body index (BBI) showed that the mean value was 21.99±3.44 with minimum values of 9.10 and maximum values of 39.16.Tribe and age both had a significant effect on Brain body index at 0.01 levels of significance. Gender had no effect on BBI at 0.05 levels of significance. Mean separation showed that the effect of tribe on Brain body index was mainly a result of the Urhobo tribe which had an average value of (21.39). The Ibo (22.51) and Edo (22.24) tribes had similar values. In spite of these observations, differences which enabled intracultural differentiation commonly occurred.
CONCLUSION: Craniometric studies involving brain body index are most essential in the study of population dynamics especially with respect to quantitative variables.
