“…Las dos principales limitaciones atribuidas al R24H fueron controladas; la relacionada con la determinación de la ingesta usual fue atendida al aplicar un segundo R24H en una submuestra y utilizando el método desarrollado por la universidad de IOWA (26,27,34). La relacionada con la subjetividad de los tamaños de las porciones tradicionalmente reportadas por los sujetos, fue anulada en este estudio, al utilizar tamaños medios de porción derivados de estudios poblacionales obtenidos con base en referentes de oro -registros repetidos con pesaje de alimentos y en diferentes estaciones climáticas- (29)(30)(31). La EPSA nunca fue sometida a validaciones como esta, por lo que es imposible comparar los resultados.…”

“…La información sobre las preparaciones y alimentos consumidos fue codificada con base en una tabla de composición de alimentos y preparaciones para esta población (28). El tamaño de la porción fue asignado con base en los establecidos en estudios poblacionales (29)(30)(31). La traducción de los registros del R24H a nutrientes se realizó con FoodCalc v. 1,3 (32).…”

“…Con lo aquí presentado la respuesta es un rotundo no; no, al menos cuando se relacionan estas diecisiete variables. Colombia ha gastado importantes sumas de dinero en dos encuestas nacionales en donde la EPSA y la ELCSA fueron los métodos de elección para declarar la inseguridad alimentaria (9,10); también, ha utilizado los R24H con el fin primario de establecer la calidad de la dieta en estudios nacionales y regionales (9,35,36) y, ahora, para establecer variables asociadas a inseguridad alimentaria. Por lo aquí demostrado, no es pertinente, ni política o administrativamente útil, cualquiera de estos cinco métodos para declarar la inseguridad alimentaria con fines de elaborar la política social.…”

Introducción. La vigencia de las explicaciones cambia con las transiciones demográfica, epidemiológica y nutricional. Objetivo. Establecer la magnitud de inseguridad alimentaria y sus variables asociadas. Materiales y métodos. Se clasificaron 432 hogares mediante cinco métodos; se utilizaron las escalas de percepción de seguridad alimentaria (EPSA), la latinoamericana y caribeña (ELCSA), y otros tres: a) según el consumo usual de energía del jefe del hogar, b) según el consumo usual de energía de todos los miembros, y c) según un algoritmo basado en el consumo y la condición de los menores. Mediante regresión binomial, se establecieron las variables asociadas a la inseguridad alimentaria. Resultados. La inseguridad varió entre 35,9 y 87 %. Según la ELCSA y b), los hogares con menores tienen menor riesgo de inseguridad 0,51 (IC 95% 0,25-0,90) y 0,72 (IC 95% 0,48-0,96). Según la EPSA y la ELCSA, no pagar los servicios públicos 1,75 (IC 95% 1,23-2,28) y que el jefe del hogar declare que no accede a los alimentos 1,48 (IC 95% 1,20-1,68), aumentan la inseguridad. Obtener ingresos esporádicamente se asoció con el método a), 1,34 (IC 95% 1,04-1,53) y el método b), 1,32 (IC 95% 1,03-1,52). Pagar arriendo 1,12 (IC 95% 1,01-1,16), el tiempo de permanencia en el municipio 0,59 (IC 95% 0,23-0,93) y no contar con alcantarillado 1,13 (IC 95% 1,01-1,16), se asociaron a la inseguridad por el método c). Conclusiones.No es pertinente o útil recomendar estos métodos con fines de elaborar la política social.Palabras clave: seguridad alimentaria, consumo de energía, prevalencia, política social, pobreza, Colombia.doi: http://dx.doi.org/10.7705/biomedica.v32i4.766Food insecurity: associated variables and issues for public policy Introduction. The validity of the explanations change over time according to the state of demographic, epidemiological and nutritional transitions. Objective. Five methods were compared to establish the magnitude of food insecurity and related variables. Material and methods. Four hundred and thirty-two households in Colombia were classified using five methods, including (1) the scale of perceptions of food safety (EPSA), (2) the Latin American and Caribbean scale (ELCSA), (3) the usual intake of energy from the head of household, (4) the usual consumption of energy of all members of the home, and (5) an algorithm based on consumption and status of children. Binomial regression established variables associated with food insecurity. Results. Insecurity varied between 35.9% and 87.0%. According ELCSA and method 3, households with children have a lower risk of insecurity, 0.51 (95% CI 0.25 to 0.90) and 0.72 (95% CI 0.48 to 0.96). Under the EPSA and ELCSA, increased insecurity is associated with nonpayment of utilities, 1.75 (95% CI: 1.23 to 2.28) and the head of household declared limited access to food, 1.48 (95% CI: 1, 20 to 1.68). Sporadic income was associated with the method 3, 1.34 (95% CI 1.04 to 1.53) and method 4, 1.32 (95% CI 1.03 to 1.52). Paying rent, 1.12 (95% CI: 1.01 to 1.16), time spent in the mu...

“…For the three alcohol intake estimation methods (30-DR, AFQ-A, AFQ-B), the individual intake of alcohol per type of source drink was estimated by summing the products of the volume of drink consumed and the quantity of alcohol contained in the beverage, using FoodCalc 15 together with the food composition table 13 . To calculate the alcohol consumed from the AFQ-B, the specific means of alcohol intake were used, by sex, in each of the five items.…”

Objective: To determine the relative validity and reproducibility of two alcohol intake frequency questionnaires (AFQ-A; AFQ-B), designed to classify subjects according to their alcohol intake level, in Bucaramanga, Colombia. Method: One hundred and nine randomly selected subjects, aged between 20 and 60 years, completed three 30-day semi-quantitative alcohol intake records (30-DR). The AFQs were applied three months after the last 30-DR. AFQ-A contained 53 items; AFQ-B contained five items, with the alcoholic drinks for AFQ-B selected by Max_r. The correlation and agreement between alcohol intake assessed with the AFQs and the 30-DR were obtained using Pearson's correlation coefficient (r), Lin's concordance correlation coefficient (r C ), Spearman's rank correlation coefficient (r S ), Bland and Altman's limits of agreement (LOA) and Cohen's weighted kappa statistic (K w ). Results: The reproducibility of the 30-DR was poor; r S ranged from 0.33 to 0.41. The reproducibility of the AFQs was higher, with r S between 0.50 and 0.73. The agreement (K w ) of the 30-DR and the AFQs was 0.40. The lower and upper LOA were between 2 56.4% and 211.0%. The AFQs and 30-DR were well correlated. Assessment of relative validity between the two methods yielded r values for alcohol between 0.52 and 0.60, which reduced to 0.20-0.29 after energy adjustment. Conclusions: These AFQs may be useful to rank subjects according to their alcohol intake. The AFQ-B is easy and quick to apply, and is also highly cost-effective. Keywords Alcohol consumption Food-frequency questionnaire Max_r ColombiaDuring the last 50 years, Colombia -like many other countries of the world -has experienced demographic and epidemiological transitions. The changes attributed to these transitions include ageing of the population, changed dietary habits to high intakes of foods rich in fats, sugar and salt, and increased alcohol consumption 1 -3 . The prevalence of alcohol consumption has increased in Colombia during the last 15 years, reaching 86% among the population older than 12 years in 1997, and also the age at which consumption begins has decreased to 9 years old 4 -6 . Despite the need to quantify alcohol intake and establish whether or not it is related to dietary habits, chronic diseases, trauma and social or mental diseases, there are no valid instruments available for this purpose in Colombia.Even when alcohol is not a nutrient, methods used in the study of diet can be applied in the quantification of alcohol consumption 7 . The research on dietary intake and its relationship with chronic diseases has been carried out with simplified questionnaires that ask about the dietary pattern before the disease. Alcohol frequency questionnaires (AFQs) have been the most useful tool in epidemiological research 7 -9 , not only for their low cost but also because they result in good classification of subjects based on their intake. Moreover, the level of intake can be measured with more validity 10 . However, alcohol consumption is a difficult-to-m...
