Abstract: Background: Children overweight/obesity is an important risk factor for many health problems and an indicator of heart problems and diabetes mellitus later in life. There are numerous methods of assessing overweight and obesity. Children overweight is most commonly described by using BMI which does not adequately describe regional (central) adiposity, other indices of body fatness are being explored. The possible role of NC in screening for high BMI in children is not well characterized. The aims of this study were to examine the correlation between BMI and NC in children and to determine the best NC cutoff that identiﬁes children with high BMI. Methods: Cross sectional study included 2762 preparatory school children, trained research assistants collected clinical data and anthropometric measurements from all children. Pearson correlation coefficients were calculated between NC and other obesity indices, then receiver operating characteristic analyses were done to determine the optimal NC cutoff for identifying children with high BMI. Results: among 2762, overweight and obesity were 15.1%. NC was signiﬁcantly correlated with age, BMI, and waist circumference in both boys and girls. Optimal NC cutoff indicative of high BMI in boys ranged from 29.3 to 31.7 cm, while corresponding values in girls ranged from 28.6 to 30.8 cm. NC was a good indicator for BMI and even as good as WC. Conclusions:NC is signiﬁcantly correlated with overweight/obesity and can reliably identify children with high BMI. NC is a simple technique that has good inter-rater reliability and could be used to screen for overweight and obesity in children.
