Resumo: | ObjectiveThis study assessed the agreement between self-reported and measured weight and stature in adolescents. MethodsNinety-seven students from public and private high schools of Cuiabá, in the state of Mato Grosso, Brazil (14 to 19 years old), were examined to assess the validity of self-reported weight and stature. The adolescents reported their weight and stature, which were subsequently measured by standard procedures. The body mass index was calculated from both self-reported and measured data. Weight status was classified according to body mass index Z-score and World Health Organization criteria. The differences between the self-reported and measured means were tested by the Student’s paired t-test. Weighted Kappa’s coefficient of agreement wasused to assess the variations in weight status categorization using informed and measured data. Agreement between measurements was assessed by the Bland-Altman method and intraclass correlation coefficient. ResultsThe means of self-reported and measured weights (p=0.30), statures (p=0.76) and body mass index (p=0.47) were not significantly different. There was high agreement between self-reported and measured measurements according to intraclass correlation coefficient (weight: r=0.99; stature: r=0.96; body mass index: r=0.97) and the mean agreements estimated by the Bland-Altman method were 99% for weight and 100% for stature. ConclusionGiven the excellent agreement with measured data, self-reported weight and stature are considered valid to be used in epidemiological studies on adolescents of Cuiabá, Mato Grosso, Brazil. |

ObjetivoAvaliar a concordância entre as medidas de peso e estatura autorreferidas e aferidas em adolescentes. MétodosNoventa e sete estudantes de 14 a 19 anos de idade do ensino médio público e privado de Cuiabá, (Mato Grosso) foram examinados a fim de se avaliar a validade de medidas de peso e estatura autorreferidas. Os adolescentes referiram o peso e a estatura e, na sequência, as respectivas medidas foram aferidas com base em procedimentos padronizados. O índice de massa corporal foi determinado a partir das medidas estimadas e aferidas. O status de peso foi classificado com base no escore-Z do índice de massa corporal segundo proposta da Organização Mundial da Saúde. Utilizou-se o teste t de Student pareado para avaliar as diferenças entre as médias das medidas autorreferidas e aferidas. O coeficiente de concordância Kappa ponderado foi utilizado para se avaliarem as variações na categorização do status de peso estimado a partir de medidas informadas e aferidas. A concordância entre as medidas foi avaliada pelo método de Bland-Altman e pelo coeficiente de correlação intraclasse. ResultadosNão se observaram diferenças entre as médias das medidas autorreferidas e aferidas de peso (p=0,30), estatura (p=0,76) e índice de massa corporal (p=0,47). Houve elevada concordância entre as medidas autorreferidas e aferidas de acordo com o coeficiente de correlação intraclasse (peso: r=0,99; estatura: r=0,96; índice de massa corporal; r=0,97) e segundo o método de Bland-Altman (concordância média: peso=99%; estatura=100%). ConclusãoDada a excelente concordância com as medidas aferidas, o peso e a estatura autorreferidos são considerados válidos para serem utilizados em estudos epidemiológicos com adolescentes de Cuiabá.
