Background: Body Mass Index (BMI) which is often calculated by dividing the weight (kg) by height squared (m2), was chosen as a simple measurement of body weight in relation to height. Waist circumference (WC) and Waist-hip-ratio (WHR) are important indices to assess abdominal obesity. Waist circumference (WC) is an expedient and easy measurement of intra-abdominal fat mass and total body bulk.Methods: This cross-sectional study was conducted on 130 undergraduate students of University of Maiduguri (comprising of 65 male students and 65 female students), with their ages ranging from 18-30 years. A written or verbal consent was obtained from the subjects after explaining to them the objectives as well as the methodology of the study.  Information about age and socioeconomic status was collected from each student in a pre-designed questionnaire. The height, weight, waist circumference, hip circumference were also taken on each individual using standard anthropometric methodology.Results: The prevalence of abdominal obesity in the present study, according to waist circumference (WC), and waist-hip-ratio (WHR) was 24.6% and 67.7% in males respectively, while 66.2% and 92.3% in female students respectively. Conclusion: The females in the same age group as males showed a tendency towards higher BMI and were classified as overweight and this could be attributed to reduced physical exercise and diet compared to their male counterparts.Keywords: body mass index, hip circumference, obesity, waist circumference, waist-hip ratio

Introduction Knowledge of the evolutionary relationship between different classes of vertebrates can be obtained through a comparative study of their structures, forms, functions, and of the mode of development of the structures. Birds and mammals are vertebrates with different modes of reproduction, that is, oviparity in birds and viviparity in mammals. The aim of the present study is to compare the histomorphology of the ovaries and of the oviducts/uterine tubes in rabbits and pigeons. The present study highlights the histological and morphological differences that bring about the production of eggs in birds and the production of fully developed fetuses in mammals. Materials and Methods Five rabbits and five domestic pigeons were anesthetized with chloroform and sacrificed. The ovaries and the oviducts/uterine tubes were dissected and fixed in Bouin fluid and processed for a light microscopic study. Results The result showed paired ovaries and uterine tubes in rabbits that unite at the isthmus to form a single uterus that opens into the vagina, with only the left ovary and oviduct appearing as a compact body with distinct infundibulum, magnum, isthmus, uterus and vagina in pigeons. Photomicrographs of the ovaries of rabbits showed parenchyma cells with primary follicles, while the ovaries of pigeons showed developing follicles and yolk granules. Both the oviducts of rabbits and of pigeons showed a highly folded mucosa with a thick muscular wall. Conclusion The differences observed in the structures of the ovaries and of the oviducts of rabbits and pigeons might be due to their different reproductive functions in parturition (viviparity and oviparity, respectively).
