Valores críticos do índice de massa corporal para classificação do estado nutricional de crianças e adolescentes brasileiros

Abstract: Objective: To delineate a classification system, comprising reference curves and cutoff points, based on the distribution of body mass index (BMI) across a national reference population and designed for the assessment of the nutritional status of Brazilian children and adolescents.Methods: Data from 13,279 males and 12,823 females aged from 2 to 19 years, extracted from the National Nutrition and Health Survey dataset (1989), were used to construct a reference curve. The LMS method was employed to calculate th… Show more

“…23,a The body mass index (BMI) was obtained from the ratio between weight (kg) and square of the height (m 2 ), based on self-reported measures. The following cut-off points, derived from the Brazilian population, 6 were used to classify the BMI: "normal weight" (low weight and normal weight) and "overweight" (overweight and/ or obesity). Self-reported measures of weight and height show a high agreement with the objective evaluation and they are frequently employed in studies conducted with adolescents.…”

“…Dessa forma, o presente estudo configura-se como a primeira tentativa nacional de proposição de pontos de corte (12), os resultados de sensibilidade e especificidade encontrados apresentaram valores que podem ser considerados satisfatórios para triagem de escolares com risco aumentado para a presença de fatores de risco para DCV. Resultados prévios corroboram com os achados do presente estudo, indicando que tais propostas de pontos de corte para o IMC apresentam adequada capacidade de identificar indivíduos portadores de fatores de risco para DCV (9).…”

“…Contudo, algumas considerações devem ser feitas. Do ponto de vista metodológico, as propostas foram baseadas nos valores que em adultos apresentam maiores chances de desenvolvimento de DCV (6,12), ou em escolhas arbitrárias na distribuição dos valores do IMC da população (7). Mesmo com adequada concordância com a adiposidade, os valores dos pontos de corte desses estudos não garantem que indivíduos que ultrapassam seus valores tenham maior probabilidade de apresentar fatores de risco para DCV.…”

“…Para a classificação do IMC utilizou-se como referência as curvas de percentis, recomendado por Conte e Monteiro (13) que indicaram como ponto de corte valores < 17,5kg/m 2 para baixo peso, > 25kg/ m 2 para sobrepeso e >3 0kg/m 2 para obesidade.…”
