摘要:In the last decades, the obesity prevalence has increased in worldwide, and is necessary to be followed. The aim of the presented study was to analyze the efficiency of Brazilian body mass index cutoffs in the nutritional status indication. A sample of 1384 subjects was evaluated, with age ranging from 10 to 17 years old. Were assessed the body weight, stature (body mass index), and the triceps skinfold. For the male gender, the sensibility’s scores were 43.8% (overweight/obesity) and 5.6% (malnutrition). For the female gender, the sensibility’s scores were 31.4% (overweight/obesity) and 5.7% (malnutrition). The specificity’s scores were 72.5% (overweight/obesity) and 99.1% (malnutrition) for the male gender, and equal to 84.2% (overweight/obesity) and 96.1% (malnutrition) for the female gender. The analyzed body mass index cutoffs are more specific than sensitive in the nutritional status identification.
