Abstract: El conflicto armado en Colombia, produce desplazamiento de familias marginadas del estado, constituyéndose en tragedia humanitaria. Las mujeres en estas familias son muy vulnerables y su dieta es una expresión de miseria. Se analizó el consumo dietario en 102 madres con tres a os de desplazamiento forzado, a través de un recordatorio del consumo de las últimas 24 horas. La energía disponible es deficitaria para todas, y hay imbalance en la dieta; el 71% de la energía/día proviene de carbohidratos, 12% de proteínas y 20% de grasa. La adecuación (%) entre lo consumido y lo requerido para todos los macro y micronutrientes, esta por debajo de niveles considerados como aceptables; el mínimo para el calcio (mg) 30,8% IC (27,4 a 34,7); el máximo para el ácido ascórbico 81,5% IC (71,1 a 93,4). Las cifras de déficit según el índice de masa corporal son tres veces mayores que en la población pobre. Intervenciones por mejorar la dieta son deseables, pero es necesario además involucrar soluciones de tipo estructural, para evitar que esta tragedia se haga cada vez más crónica y endémica, violentando el derecho básico a la alimentación The armed conflict in Colombia produced a displacement of excluded families from the country, constituting a humanitarian tragedy.

Abstract: Durante los a os 2007-2008 se realizó en Lebrija, Colombia, un estudio para evaluar el impacto de dos estrategias implementadas en familias de ni os escolarizados, que tuvieron como objetivo incrementar el consumo de frutas y verduras en el hogar. Dieciséis hogares fueron intervenidos con la estrategia A. Veintitrés hogares fueron intervenidos con la estrategia B. Treinta y cuatro hogares sirvieron como controles. Las estrategias incluyeron entre otros, talleres informativos, preparación de recetas, actividades grupales y evaluación de tareas. En los hogares intervenidos el 3,0% en la línea de base consumían cinco o más porciones, al finalizar las estrategias aumentaron al 26,3%, un incremento de 8,8 veces. En el grupo control al inicio este consumo recomendado de cinco o más porciones/día fue de 2,0%, al final de 0,0%. El aumento no fue diferencial dada la estrategia de intervención, en la estrategia Apaso del 0% de hogares en la línea de base al 23,5%, en la B del 4,3 al 28,6%.

Abstract: El objetivo fue estimar la cantidad de alcohol consumida (g) por adultos de Bucaramanga, y describir el consumo por las variables derivadas del mismo; consumo problemático, riesgo de alcoholismo y tipología del consumidor. Durante 2006 un total 1.119 sujetos respondieron cinco encuestas, entre ellas, un cuestionario de frecuencia de consumo validado en esta población. Los hombres consumen en promedio 69,4 g semanales de alcohol (IC; 64,1 a 75,2), las mujeres 34,1 g (IC; 30,9 a 55,7), p=0,000. El 55,4% de la población excede el límite de consumo semanal en unidades internacionales; 70,4% los hombres y 40,9% las mujeres respectivamente, p=0,000. La cantidad de energía asociada a la ingesta de alcohol fue de 781 kilocalorías (IC; 696 a 894), de estas el 20% (159 kilocalorías, IC; 138 a 179) son derivadas de bebidas acompa antes, como las tipo cola. Seis variables explican en 33% la cantidad de alcohol consumido; el sexo, la edad, el nivel socioeconómico, la frecuencia de consumo, el gusto por las bebidas y el consumo problemático.

Abstract: Introduction. The consequences of alcohol intake can be public health problems. A well-constructed classification system of alcohol consumers will assist in designing strategies for mitigation and control of alcohol-induced behaviors. Objective. A categorization of alcohol consumers was developed based on a set of consumer-associated variables. Material and methods. A set of 1,199 subjects between 18 and 60 years old was selected and each subject classified in three categories of alcohol intake: type A, intake desirable; type B, excessive consumption without related problems; and type C, problematic consumption or dependence. Using multinomial logistic regression model, the decisive variables of each category were fixed. Results. Subject with positive expectations associated with consumption such as “increase in expressivity and the sexuality” have 1.6 (95% CI; 1.0 - 2.5) times greater probability to be placed in the C category that those without those expectations. For relationships associated with “inhibition and feelings of power”, this risk even greater- 2.2 (95%CI; 1.1- 4.3). Age is in an inverse relationship and a protective factor to be classified type B or C. Men have a greater probability than women to be classes in B or C; this probability is the same as subjects who indicate having moderate pleasure or a rise in pleasure induced by the alcoholic drinks. Discussion. The results can be translated into programs for interventions at the population level directed to groups of higher risk, such as scholars and preteens, and with a gender focus. The personality element on which to focus the intervention is that of self-esteem. This is an element built from a behavioral-cognitive perspective within the context of the social and cultural learning process. Introducción. En Colombia algunas consecuencias del consumo de alcohol son problemas de salud pública. Es necesario clasificar adecuadamente a los consumidores para dise ar estrategias de mitigación y control. Objetivo. Establecer los tipos de consumidores de alcohol y sus variables asociadas. Material y métodos. Se clasificaron 1.199 sujetos entre 18 y 60 a os en tres tipos de consumo de alcohol: tipo A, consumo deseable; tipo B, consumo excesivo sin problemas relacionados; y tipo C, consumo problemático o dependencia. Mediante regresión logística multinomial, se establecieron las variables asociadas a los diferentes tipos. Se discute sobre la implicación de los resultados. Resultados. Los sujetos con expectativas positivas hacia el consumo ligadas con la expresividad y la sexualidad tienen 1,6 (IC9

Abstract: the incorrect measurement of the diet produces an attenuation or dilution of epidemiologic measures. the variation within-person and between-person are the main determinant of this effect. to describe the variability of the diet of a colombian city, the record of the dietary intake survey of 167 adults carried out during seven days and in different seasons, during 1998-2003, was analyzed. using analysis of variance (anova), error within-person and between-person, was calculated the reason within-person/between-person, and the variation coefficients for the absolute values, transformed and adjusted by the energy using lineal regression. the reason within-person/between-person is not different for sex and smaller than 1 for all the nutritional variables, except for dietary fiber, iron and manganese. the error between-person was explained by the subjects, sex and the day of the week. with an error margin between 10% and 15%, it is viable in this population to study the diet correctly. the drop variability within-person will attenuate little the measures of absolute effect calculated in epidemic studies. however, the diet is homogeneous and characteristic of a poor country, what will hinder to find relationships between diet and illness

Abstract: the aim of this study was to assess reproducibility in four colombian cities of the results obtained on food insecurity (insa) comparing it with the factorial and criterion validity of the food security perceptions scale (epsa) and the latin american and caribbean (elcsa) methods in homes from urban and rural area based on the usual consumption of energy for all household members. the reproducibility was 051 for epsa and 056for elcsa . the sensitivity of the epsa was between 39.6% and 40.5% and for the elcsa between 62.6% and 622%. the agreement against the reference for the epsa was between 0.10 and 018for elcsa was between 0.09 and 0.13. the efficiency of the two tests as a global measure of reliability is just greater than the probability in a coin toss. the results of these scales should be used conservatively.

Abstract: the measurement of dietary intake is complex. the analysis methods, when used incorrectly, can distort reality generating a waste of resources and opportunities to intervene appropriately at the individual and population level. the intake records of seven consecutive days of 167 subjects were analyzed using the methods proposed by the university of iowa and compared with the values of reference of dietary intake (dri's). the variation in energy consumption compared with recommendations was 15%. ninety two % of the men and 80% of the women's consumed protein above the recommendation (rda). the average consumption of total fiber was half of the recommendation and all the people had intakes below the rda. seventeen % consumed total fats above the rda regardless of differences in body mass index (bmi). the intake of saturated fat was twice that of polyunsaturated fat. the consumption of monounsaturated, polyunsaturated and saturated fat also did not change for different bmi. the socioeconomic level was associated to the intake of proteins and fats. it is evident that the diet is not healthy and represents a risk factor for cancer development, cardiovascular events and other chronic illnesses
