Behavioural and anthropometric risk factors for diabetes mellitus among newly admitted undergraduates in a Nigerian University.

BACKGROUND: Type 2 diabetes mellitus (DM) is fast becoming a global epidemic, and its prevalence is increasing in children and young adults. The aim of the study was to identify young adults who had type 2 DM or impaired fasting glucose as well as those at risk of these conditions using anthropometric data and behavioral pattern. METHODOLOGY: Two hundred and twenty newly admitted undergraduates who were randomly selected during the registration process were involved in the study. Anthropometric parameters were measured while information on demographic details, medical history, and family history were obtained using a standard questionnaire. Fasting blood glucose was measured using the glucose oxidase method. RESULTS: Two hundred and seven (94%) participants had serum glucose within reference range, 10 (4.6%) had impaired fasting glucose, and 3 (1.4%) had serum glucose> 7.1 mmol/L, which is indicative of DM. A large number (91.4%) of individuals engaged in physical activity equivalent to a walk of at least 30 min/day. Most of them (93.2%) had body mass index <25.0 while 6.8% were overweight. One hundred and three participants (46.8%) indicated that they eat 3 or more servings of whole grain per day. CONCLUSION: Most of the participants are involved in healthy lifestyle. This has resulted in very low prevalence of impaired fasting glucose and type 2 DM among the group. It will be useful to follow up the group and note if they are able to maintain this trend since the risk of developing DM is known to increase with age.

Antinociceptive profile of the methanolic extract of Neorautanenia mitis root in rats and mice.

The antinociceptive activity of the methanolic extract of Neorautenania mitis was studied in mice and rats. Five experimental models of nociception employed were: acetic acid-induced abdominal constriction and hot-plate test in mice, formalin-induced pain, analgesy-meter and Randall-Selitto tests in rats. The antinociceptive action of the extract was tested against naloxone in the hot-plate test in a bid to further elucidate probable mechanisms of antinociception. Results showed that the extract at doses of 5, 10 and 20 mg/kg body weight caused significant (P<0.05) dose-dependent antinociceptive activity in all the nociceptive models. Naloxone (2 mg/kg), significantly (P<0.05) antagonised the antinociceptive activity at the highest dose of the extract (20 mg). The study showed that the methanolic extract of Neorautanenia mitis possesses both peripherally and centrally mediated antinociceptive activity. The peripherally mediated action may be linked partly to lipoxygenases and/or cyclo-oxygenases, while the central anti-nociception is likely to be mediated via opioid receptors in the CNS.
