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.

[Development of questionnaire to assess food intake in the University of Antioquia, Colombia]. / Diseño de un cuestionario de frecuencia para evaluar ingesta alimentaria en la Universidad de Antioquía, Colombia.

OBJECTIVE: To design a self-reported semi-quantitative questionnaire of frequency of food intake (QFFI) to assess the usual intake of foods and macronutrients of the academic community from the University of Antioquia (UoA). METHODOLOGY: The design of the questionnaire was done by reviewing and analyzing previous studies on food intake and the established linings for the selling of dietary products at the UoA. For selecting the foods and defining the serving size, we applied the criterion of intake pattern and the weight or size of the most frequent serving for each food, according to what has been reported in previous studies. We undertook a descriptive exploratory study with the QFFI including 154 people of the UoA. The analysis included the comprehension, applicability and comprehensiveness of the instrument for the participants, as well as the calculation of the descriptive parameters in the exploratory component. RESULTS: A semi-quantitative QFFI compounded by 144 foods classified in 9 groups with serving sizes known by the population and 9 categories of frequencies of usual intake within the last year. The exploratory study showed differences in the pattern of intake in the population groups analyzed. CONCLUSION: The designed QFFI was adequate for the study population since it was easily understood and administered, and it allowed for assessing the usual intake in the community of the UoA.

Mapping public policy options responding to obesity: the case of Spain.

This study assesses the opinions of the main Spanish stakeholders from food and physical exercise policy networks on public policy options for responding to obesity. We followed the multi-criteria mapping methodology in the framework of the European project 'Policy options in responding to obesity' (PorGrow), through a structured interview to 21 stakeholders. A four-step approach was taken: options, criteria, scoring and weighting, obtaining in this way a measure of the performance of each option which integrates qualitative and quantitative information. In an overall analysis, the more popular policy options where those grouped as educational initiatives: include food and health in the school curriculum, improve health education to the general public, improve the training of health professionals in obesity care and prevention, incentives to caterers to provide healthier menus and improve community sports facilities. Fiscal measures as subsidies and taxes had the lowest support. The criteria assessed as priorities were grouped as efficacy and societal benefits. Obesity in Spain can be approached through public policies, although the process will not be easy or immediate. The feasibility of changes requires concerned public policymakers developing long-term actions taking into account the map of prioritized options by the stakeholders.
