EATING HABIT AND NUTRITIONAL STATUS OF A NIGERIAN PRIVATE UNIVERSITY STUDENTS

The study aimed at determining the eating habit and nutritional status of Babcock university undergraduate students. Multiple stage random technique and systematic sampling was used to select 288 respondents and a structured questionnaire was used to elicit information on the socio-demographic data and eating habit. The BMI of the respondents was determined using weight and height squared and the 24- hour dietary recall was analyzed using Total Dietary Assessment software. The relationship between eating habit and nutritional status was determined using Chi- square.  Most of the respondents in the study were between 18-21 years (73.6 %) consisting of 45.6 % male and 53.7 % female. The respondents (54.8 %) consumed two meals in a day, 63.9 % eats in response to hunger while others eat due to different factors. Consumption of fruits and vegetables was poor as only 17.0 % and 14.9 % consumed fruits and vegetable daily. Many of the respondents consume snack regularly (85.4 %) with 33.7 % consuming in- between meals and 14.2 % snacking late in the night. Prevalence of overweight and obesity was high among the respondents as 30.4 % were overweight and 27.1 % were obese. Mean calorie intake and % RDA being 3223.04± 687.66 and 111.14 for males and 2429.45 ± 243.14 and 110.43 for females.   Frequency of consumption, snacking, period of snacking, soft drink consumption and, poor fruit and vegetable consumption all had significant (P< 0.05) effect on the nutritional status.                               &nbsp

Ocular morphology of the fruit bat, Eidolon helvum, and the optical role of the choroidal papillae in the megachiropteran eye: a novel insight

Background: This work was designed to provide a morphologic, morphometric and histochemical description of the eye of the African straw-coloured fruit bat (Eidolon helvum). An explanation of the optical role of the choroidal papillae in the vision of megachiropteran bats was provided. Materials and methods: Enucleated eyes of captured fruit bats were measured and processed for light microscopy. Results: Typical gross features of the mammalian eye including an anterior transparent cornea, posterior whitish sclera and a golden-brown iris surrounding a round pupil were observed in the eye. Presence of undulating retina typically found in megachiropterans were also seen. The ratio of mean corneal diameter to mean axial eye diameter was 0.58 ± 0.08. The histochemical investigation of the eye indicated the presence of mucins, proteoglycans, hyaluronic acid, glycogen and/or glycoproteins in the corneal, scleral, choroidal and retinal tissues. Conclusions: The presence of reflective materials of the tapetum lucidum on the undulating retina was shown to be a morphological adaptation for increased light sensitivity as each parabolic surface of the choroidal papillae served as a convex mirror, reflecting the light rays to the adjacent parabolic surface, thus sensitizing photoreceptors in affected regions. This phenomenon thus empowers megachiropteran bats with improved scotopic visual capability and could explain why most of them are reliant on their vison without the need for echolocation
