Resumo: | The aim of this study was to evaluate the use of self-reported measures for calculating body mass index (BMI) and nutritional status. A cross-sectional quantitative study was conducted on 1,000 students. Body weight and height were measured by a trained evaluator and were obtained by self-report of the participants. There was a trend towards underestimation of body weight by 0.3 kg and overestimation of height by 1.0 cm, which resulted in lower self-reported BMI compared to measured BMI (p <0.001; r = 0.34). Analysis of agreement with measured BMI showed very high reliability of self-reported BMI. The evaluation of nutritional status based on measured BMI resulted in an increase in the percentage of eutrophic individuals (+2.3%) and a decrease in obese individuals (-3.2%). This decrease was greater among men (-6.1%). A change in nutritional status classification occurred in 14.5% of the participants when evaluated by self-reported BMI. In conclusion, there is good agreement between self-reported and measured BMI, but the results suggest caution in the use of self-reported BMI alone or as a continuous variable. Categorized information seems to be more appropriate for the classification of nutritional status. |

Foi realizado um estudo quantitativo transversal com amostra constituída de 1000 estudantes avaliados quanto ao peso e estatura aferida e informada. Foi identificada uma subestimação do peso e superestimação da altura o que resultou em uma mediana das medidas informadas menor que a das medidas aferidas. A confiabilidade do IMC informado, foi considerada muito alta e moderada. Foi observado um incremento do percentual de voluntários eutróficos e diminuição de obesos. A concordância da classificação do estado nutricional foi considerada boa com alta especificidade quanto à categorização do estado nutricional. Apesar da boa concordância, os resultados sugerem cautela em seu uso de forma isolada ou como uma variável contínua, parecendo ser mais adequada a utilização da informação categorizada, enquanto classificação de estado nutricional.
