Body mass index and blood pressure pattern of students in a Nigerian university

Abstract

Purpose: Reports in Nigeria and other developing countries have indicated a rise in the prevalence of obesity among adults. In identifying at what age in our environment obesity starts becoming a problem, we measured the burden of overweight and obesity among young adults. Methods: Four hundred and sixty four undergraduate students, who were undergoing medical examination as part of admission process, were recruited. Their weight, height and blood pressure (BP) were measured and their body mass index (BMI) was calculated. The prevalence of obesity, overweight and under-nutrition among these students were determined according to international guidelines. Results: The prevalence of obesity (3.4%) and undernutrition (3.1%) among the students, were similar. Female students had higher prevalence of obesity (4.02%) and under-nutrition (3.1%) than the males. Overweight was found to be commoner in male subjects (26.78%) than in females (20.98%). The prevalence of hypertension was 3.4% in the study population and was commoner in males (5.9%) than in females (0.89%). Mean systolic blood pressure and diastolic blood pressure were significantly higher in males than females (p < 0.05). Conclusion: Obesity and under-nutrition are prevalent among the fresh undergraduate students. As part of the orientation programme for fresh undergraduate students in Nigerian Universities, nutrition education should be carried out. The need to always conduct blood pressure monitoring for all University students is also recommended. Keywords: Body mass index; Blood pressure; Obesity; University students; Nigeria.
