Comparación entre variables antropométricas auto reportadas y mediciones reales

El objetivo de este estudio fue valorar el autoreporte de peso, estatura y perímetro de cintura, y comparar dicha percepción con los valores reales en estudiantes universitarios participantes de la Cohorte MESPYN, -Medellín, Salud Pública y Nutrición- de la Universidad de Antioquia (UdeA) - Colombia. Se realizó un estudio transversal a partir de la primera medición de la Cohorte MESPYN 2009-2010. La muestra incluyó estudiantes voluntarios de las diferentes áreas académicas. La autovaloración de peso, estatura y perímetro de cintura se registró antes de la toma de los datos reales. Se calcularon coeficientes de correlación intraclase (CCI) para todas las variables (α=0,05); la concordancia entre medidas reales y autoreferidas se valoró según el método de Bland y Altman. Se incluyeron 424 estudiantes voluntarios. El peso promedio real de hombres (kg) fue 67,4±10,4 y autoreportado: 67,0±11,0; en mujeres el valor real: 55,7±10,1 y autoreportado: 55,0±9,0. La estatura promedio real (m) en hombres fue 1,73±6,1 y autoreportada: 1,73±6,0; en mujeres el valor real: 1,60±5,9 y autoreportado: 1,61±6,0. En hombres el perímetro de cintura promedio real (cm) fue 76,6±8,0 y autoreportado: 75,0±14,0; en mujeres el valor real: 69,9±8,0 y autoreportado: 70,0±9,0. El CCI para peso: 0,956, IC95% (0,95; 0,97), (p<0,01); CCI para estatura: 0,953, IC95% (0,91; 0,97), (p<0,01) y CCI para perímetro de cintura: 0,593, IC95% (0,55; 0,65), (p<0,01). En conclusión, la evaluación nutricional antropométrica de estudiantes de la UdeA puede realizarse por datos autoreportados para peso y estatura, pero la evaluación de obesidad abdominal requiere la toma directa del perímetro de cintura.

Comparison of self-reported anthropometric variables and real measurement data . The objectives of this study were to evaluate self-reporting of weight, height, and waist circumference, and to compare that perception with the real measurements in college students of the MESPYN cohort -- Medellin, Salud Pública y Nutrición -- from the University of Antioquia (UdeA), Colombia. A cross-sectional study was conducted starting with the first measurement of the MESPYN Cohort 2009-2010. The sample included volunteer students from different academic areas. Self-perception of weight, height, and waist circumference were recorded before the real measurements were performed. Intraclass correlation coefficients (ICC) were calculated for all the variables, and an alpha of 0.05 was used. The concordance between real measurements and self-referred values was evaluated with the Bland and Altman method. 424 volunteer students were included. The average real weight (kg) in males was 67.4±10.4 and self-reported: 67.0±11.0; in females the real value was 55.7±10.1 and self-reported: 55.0±9.0. The average real height (m) in males was 1.73±6.1 and self-reported: 1.73±6.0; in females the real value was 1.60±5.9 and self-reported: 1.61±6.0. In males, the average real waist circumference (cm) was 76.6±8.0 and self-reported: 75.0±14.0; in females the real value was 69.9±8.0 and self-reported: 70.0±9.0. Weight ICC: 0.956, 95%CI (0.95; 0.97), (p<0.01); height ICC: 0.953, 95%IC (0.91; 0.97), (p<0.01), and waist circumference ICC: 0.593, 95%IC (0.55; 0.65), (p<0.01). In conclusion, anthropometric nutritional evaluation of UdeA students can be performed with self-reported data for weight and height, but the evaluation of abdominal obesity requires direct measurement of waist circumference.
