Introduction: Obesity is a multifactorial, chronic public health problem with concomitant diseases; since the increase in abdominal adipose tissue leads to greater synthesis and release of adipoquins and other substances, which can impair lipid and glucidic metabolism through increased insulin resistance, and increase cardiovascular risk. Objectives: analyze the effectiveness of the waist/height index and waist/hip index to diagnose abdominal obesity in children and adolescent Methods: cross-sectional descriptive study, sample 118 schoolchildren, from 5 to 15 years old who attend a sports complex. Nutritional satus was evaluated using the anthropometric technique ISAK, using the Waist/Hip index (WHI) where according to Rodriguez (2015) obesity: men 0.91, women 0.89, Overweight: men 0.83, women 0.85 and the waist/height index (WHtI) where according to Hernandez (2015) obesity: women 0.50, men 0.51, overweight: women 0.47 and men 0.48 Results: 58.5% male, 41.5% female, average age of: 8.3 , waist 62.9 cm, hip 72.69 cm, size 131.7 cm WHtI 0.67, WHI .87 , The prevalence of obesity is higher in 98.6% males vs 91.8% female, being the most predominant age group in school according to WHtI, while WHI 41.2% overweight and 26.1% obesity, the combined analysis of overweight and obesity according to sex was presented more in male population with 76.8%. The WHI was the best predictive indicator for abdominal obesity (area under the ABC curve=0.61 (95% CI, 0.48-0.73), with sensitivity 0.6, while WHtI is more predictive [area under the ABC curve=0.59 (95% IC .0.46 – 0.73) when sensitivity is < 0.6 Conclusions: The literature shows that indicators of central obesity such as WHI are related and/or better predict the metabolic risk, since it indirectly evaluates abdominal fat, in addition to indicating the type of obesity, therefore it is an excellent nutritional index to be used as a diagnostic measure of nutritional status, in addition to being simple to apply, low cost and easy to interpret, favouring the prevention of chronic degenerative non-transmissible diseases.
