Este trabalho tem por objetivos (i) estudar a correlação das medidas antropométricas com a idade
tendo em consideração o género; e (ii) verificar se há concordância entre as diversas medidas
antropométricas. Para o efeito, desenvolveu-se um estudo transversal com uma amostra de 290
adolescentes matriculados no agrupamento de escolas Emídio Garcia de Bragança. No estudo, foram
avaliados vários parâmetros antropométricos. O tratamento de dados foi realizado no SPSS 22.0
(Statistical Package for Social Sciences) e envolveu, numa primeira fase, a utilização do teste de Spearman.
Posteriormente, para avaliar a concordância entre as classificações das diversas medidas
antropométricas, efetuou-se um teste estatístico para averiguar a significância do Kappa. Por último,
efetuou-se a comparação das diversas medidas antropométricas em função do género com recurso ao
teste de Friedman. O percentil IMC e o perímetro da cintura correlacionam-se negativa e
significativamente (p<0,05) com a idade. Em contrapartida existe uma correlação positiva na
percentagem de massa gorda total com o percentil IMC e com o perímetro da cintura. Somente a
percentagem de massa gorda total e o percentil IMC apresentaram uma concordância moderada (Valor
de Kappa de 0,440). Nos demais indicadores verificou-se uma discordância de valores. Devem utilizarse
vários indicadores para avaliação do estado nutricional e não apenas um único indicador
antropométrico.
These research objectives are: (i) to study the correlation between anthropometric measures and age according to gender; and, (ii) to analyze the concordance of different anthropometric measures. This is a cross-sectional study that was conducted in 290 adolescents enrolled at the Emídio Garcia school in Bragança. In this study various anthropometric parameters were assessed. Data analysis was performed using SPSS 22.0 (Statistical Package for Social Sciences) and involved the use of Spearman’s test. Then, to evaluate the concordance between the various anthropometric measures, a statistical test to determine Kappa’s significance was performed. Finally, the comparison of various anthropometric measures according to gender, using the Friedman test, was carried out. The BMI percentile and waist circumference were negatively and significantly correlated with age. In contrast, there is a positive correlation in the percentage of fat mass with BMI percentile and waist circumference. The same correlation was found between BMI percentile and waist circumference. Only the percentage of fat mass and BMI percentile showed a moderate agreement (Kappa = 0.440), in the other indicators there was a discrepancy of values. Several indicators should be used to assess nutritional status and not just a single anthropometric indicator.
