Abstract: Aim: to estimate the population attributable risk of consumption of red and processed meat for colorectal cancer in Colombia. Methods: to model the expected incidence of colorectal cancer in the hypothetical situation of no red and processed meat consumption in Colombia, for the year 2010. A dynamic macrosimulation model, PREVENT 3.01, was used to integrate available cancer incidence, meat consumption prevalence and associated risk data and to evaluate the impact of eliminating red and processed meat from the Colombian diet on national colorectal cancer incidence. Results: Eliminating consumption of red meat altogether from the Colombian diet resulted in reductions in age-standardized colorectal cancer incidence, translating in reductions of 331 males (PAF 13%) and 297 female cases (PAF 10%). Eliminating processed meats had slightly stronger effects, with decreases of 362 males (PAF 14%) and 388 female cases (PAF 13%). Conclusions: A substantial proportion of the burden of colorectal cancer in Colombia can be attributed to the consumption of red and processed meat.
Resumen: Objetivo: estimar la fracción atribuible poblacional de consumo de carne roja y procesada para el cáncer colorrectal en Colombia. Métodos: modelación de la incidencia esperada de cáncer colorrectal en la situación hipotética de no consumo de carne roja y procesada en Colombia para el año 2010. Se utilizó un modelo dinámico de macrosimulación, PREVENT 3.01, para integrar los datos disponibles sobre incidencia de cáncer y evaluar el impacto de la eliminación de la dieta colombiana de la carne roja y procesada sobre la incidencia nacional de cáncer colorrectal. Resultados: La eliminación del consumo total de carne roja de la dieta colombiana dio lugar a reducciones en la incidencia estandarizada por edad de cáncer colorrectal, traduciéndose en la disminución de 331 casos en hombres (FAP 13%) y 297 en mujeres (FAP 10%). La eliminación de carnes procesadas tuvo efectos ligeramente más fuertes, con disminución de 362 casos en hombres (FAP 14%) y 388 en mujeres (FAP 13%). Conclusiones: Una proporción sustancial de la carga de cáncer colorrectal en Colombia puede atribuirse al consumo de carne roja y procesada.

Objetivos Evaluar durante 2007-2008 el desempeño la Escala de Percepción de Seguridad Alimentaria (EPSA) frente a la inseguridad alimentaria (IA) determinada con base en la energía usualmente consumida. Métodos Participaron 211 hogares. El responsable de la preparación de los alimentos contestó la EPSA, otro integrante del hogar contestó dos veces un recordatorio del consumo de veinticuatro horas (R24H). El referente fue la IA por el R24H y la prueba la EPSA. Resultados La IA por el R24H fue del 48,8 por ciento, con la EPSA de 19,4 por ciento. La sensibilidad de la EPSA fue de 16,5 por ciento, la especificidad de 77,8 por ciento. El acuerdo según la Kappa fue de -0,06 (IC; -0,20 a -0,03). Conclusiones Bajo el supuesto de equivalencia de métodos, la EPSA subestima la inseguridad alimentaria en el hogar. Los resultados de la EPSA comparados con los del R24H no son coherentes.
Objective Establishing the performance of the US Environmental Protection Agency (EPA) household food security scale (EPSA) which is being used in Latin-America and the Caribbean, compared to a traditionally-used method (food insecurity scale) which has led to establishing food security at individual and population level. The performance of the household food security scale (EPSA) was evaluated during 2007-2008 and compared to that of the food insecurity (FI) scale based on the energy usually consumed. Methods Two hundred and eleven household participated in the study. The person responsible for preparing food in the home answered the EPSA questionnaire. Another household member filled in a form recording the last twenty-four hours' household consumption (R24H) (on two different occasions). The study was validated by food insecurity from R24H and supposed food security from the EPSA questionnaire. Results Food insecurity by R24H was 48.8 percent and 19.4 percent on the EPSA. The EPSA had 16.5 percent sensitivity and 77.8 percent specificity. Agreement between both methods according to Cohen's Kappa was -0.06 (-0.20-0.03 CI). Conclusion Assuming equivalence of methods, the EPSA greatly underestimated household food insecurity. The EPSA results compared to those arising from the R24H were not very coherent. Some implications are discussed regarding related public policy.
