Assessment of Overweight, Obesity and the Dietary Habits of Undergraduate Students of Lagos State University

Aims: To determine the prevalence of overweight, obesity and dietary habits of under graduate students of Lagos State University.

Study Design: The study was a descriptive cross-sectional survey.

Place and Duration of Study: Lagos State University, Lagos, Nigeria, between June 2016 and July 2016.

Methodology: 150 undergraduate students were selected through multistage random sampling. Information on socio-demographic characteristics, dietary habit and physical activity was obtained using structured questionnaire. Weight, height, Percentage Body Fat (PBF), waist and hip circumferences were measured according to standard procedures to compute Body Mass Indices (BMI), Waist Hip Ratio (WHR) and finally determine nutritional status. The data were presented as frequencies, percentages, mean and standard deviations. Chi square was used to test for significant differences and level of significance set at 0.05.

Results: The mean BMI, PBF and WHR of the participants were 23.4 ± 2.3 kg/m2, 23.1 ± 5.0% and 0.83 ± 0.09, respectively. Majority of the participants (86.7%) were of normal weight while 8% (10.4% males and 5.5% females) and 5.3% (5.2% males and 5.5% females) were overweight and obese, respectively. Using WHR, more number of students were overweight/obese (34%) compared to BMI (13.3%) and PBF (8.7%), all indicated higher abnormal status among males than females. Few students exhibited poor eating (15%) and physical inactivity (16%) habits. Majority of the students (75.3%) skipped breakfast and the least daily consumed food group was legume/nut group (0.5%). Snacks (42%) and processed (20%) foods were consumed more than roots/tubers (14%) which are staple foods.

Conclusion: Central obesity was high among undergraduate students of Lagos State University. Breakfast skipping and low legume meal consumption were major dietary problems. Healthy lifestyle should be promoted among the university students to prevent overweight/obesity and its associated diseases.
