AGUILAR CORDERO, Mª J. et al. Comparative study of the effectiveness of body mass index and the body-fat percentage as methods for the diagnosis of overweight and obesity in children. Nutr. Hosp. [online]. 2012, vol.27, n.1, pp.185-191. ISSN 1699-5198.

The World Health Organization (WHO) regards obesity as one of the most serious public health problems in the world that can affect young children and adolescents. Accordingly, a major priority is to find ways to more effectively study and analyze the various methods used to diagnose and evaluate the nutritional state of the pediatric and adolescent population. The nutritional indicators currently employed for this purpose are the body mass index and body-fat percentage. However, there is a certain controversy related to the body-fat percentage since it tends to overestimate overweight and obesity. The main objectives of this study were the following: (i) to determine the prevalence of overweight and obesity in a population of primary and secondary school children between 9-17 years of age at 13 educational centers in the city and province of Granada; (ii) to verify possible differences regarding the accuracy of the body mass index and the body-fat percentage in the diagnosis of overweight and obesity.
