Ethical clearance was obtained for the study from the Senate Research and Innovation Ethics Committee of the Vaal University of Technology (20130520-3) and the Council of Scientific and Industrial Research (CSIR) (75/2013). Written permission was obtained from the School Management Board in Eastern Cape. The research was conducted according to the Medical Research Council’s guidelines for research on human beings as well as the Helsinki Declaration agreement guidelines. Prior to the study a meeting was held with the parents of the children and they were informed about the purpose of the study and the assessment to be conducted on their wards. Those that agreed signed written informed consent (parents and adolescents) and assent (children) forms, respectively.

N2 - Background: Childhood obesity has become a growing global epidemic. In South Africa, overweight and obesity during childhood and adolescence are rising. The objectives of this study were (i) to estimate the prevalence of overweight and obesity among selected students in Cofimvaba, a rural settlement in Eastern Cape province, South Africa, and (ii) to assess the accuracy of the mid-upper arm circumference (MUAC) and ultrasound triceps skin-fold thickness (TSF) methods of predicting these health parameters Methods: A cross-sectional study was conducted on 211 students (109 girls and 102 boys) selected randomly from five public schools in Cofimvaba and aged 6–19 years. The weight, height, MUAC and TSF were determined by standard techniques. Data obtained were subjected to descriptive statistics, Pearson correlations and receiver operating characteristic (ROC) curve analysis. P < 0.05 was considered statistically significant. Result: Overall 1.9% (1.8% girls and 2.0% boys) of the respondents were underweight, 14.8% (21.1% and 7.8% boys) were overweight and 2.8% (4.6% girls and 1.0% boys) were obese. The prevalence of overweight and obesity was significantly higher (p < 0.05) in girls than boys during adolescence but there was no gender difference in children (6–9 years). Most of the students (80.6%) had a healthy weight, with boys being significantly (p < 0.05) healthier than girls. The BMI showed significant strong correlations with MUAC (r = 0.926; p < 0.001) and TSF (r = 0.643; p < 0.001). ROC curve analysis gave an area under the curve (AUC) of 0.795 (95% CI, 0.761–0.889) and 0.835 (95% CI, 0.771–0.899) for MUAC and TSF respectively. Conclusion: The study found a high prevalence of overweight children in the sample and a low prevalence of stunting and underweight. The adolescent girls are at a higher risk of being overweight and obese than the boys. MUAC and TSF can adequately predict overweight and obesity among the selected students.
