Njuieyon F, et al. - In this observational study, the researchers described the predictive factors of severe obesity in children followed in French Guiana. They prospectively included the patients from the French Guianese Childhood Obesity Group database, after giving a statement of patient’s non opposition. Results of this suggested that the data could be used to inform physicians about the heterogeneity of pediatric obesity. They showed the need to incorporate waist circumference into routine clinical practice, in addition to traditional measures of weight, height, body mass index and waist-to-height ratio.
