RESUMO
Resumen Introducción: la inseguridad alimentaria (INSA) ha sido asociada a la generación de enfermedad crónica y como barrera en el tratamiento del cáncer. Ante la ausencia de estudios, establecimos a nivel ecológico la relación entre INSA y la tasa de incidencia de cáncer de colon, recto y ano x 100.000 habitantes (ICCRA). Objetivo: el objetivo fue establecer el grado de asociación entre la inseguridad alimentaria y la tasa de incidencia de cáncer colorrectal x 100.000 habitantes. Materiales y métodos: estudio ecológico realizado con información secundaria que producen regularmente las agencias del estado y que miden el nivel de desarrollo humano, social y económico en el territorio en las 33 unidades geodemográficas que conforman a Colombia. Utilizando regresión lineal múltiple con la ICCRA como la variable dependiente, la INSA como principal explicatoria y otras variables del contexto, establecimos la relación entre INSA y la ICCRA y ecuaciones predictivas de la ICCRA por sexo. La bondad de ajuste en los modelos se garantizó mediante el coeficiente de determinación (R2) y el método de Bland y Almant. Resultados: la INSA se relaciona de manera inversa y el IDH de manera directa con la ICCRA. Dos ecuaciones predicen la ICCRA; En hombres, [ICCRA=-6,38+-0,25*INSA+35,5*IDH]. En Mujeres, [ICCRA=6,47+-0,23*INSA+19,1*IDH]. El coeficiente de determinación R2 (%) en hombres es de 88 y en mujeres de 72. La diferencia media entre ICCRA observada versus la estimada fue de -0,00 en hombres (IC95 %: -3,13 a 3,13), y en mujeres de -0,00 (IC95 %: -4,08 a 4,08) Conclusión: la INSA puede estar en la vía causal de la ICCRA. La INSA y el IDH predicen con precisión la ICCRA.
Abstract Introduction: food insecurity (FI) has been associated with the generation of chronic disease and as a barrier in the treatment of cancer. Food insecurity leads to nutrient-poor diets, including dietary fiber. Colon cancer in Colombia is the third cause of death and its incidence is increasing. Objective: the objective was to establish the degree of association between food insecurity and the incidence rate of colorectal cancer x 100.000 inhabitants. Methods: ecological study carried out with information that measure the level of human, social and economic development in the territory of the 24 geodemographic units that make up Colombia. Using multiple linear regressions with colorectal cancer as the dependent variable, food insecurity as the main explanatory and other variables of the context, we established the relationship between food insecurity and colorectal cancer and predictive equations of colorectal cancer. The goodness of fit in the models was the coefficient of determination (R2) and the Bland and Alman method. Results: food insecurity is related in an inverse manner, and the human development Index is directly related to colorectal cancer. Two equations predict colorectal cancer with precision; Men, [colorectal-cancer = -6.38 + -0.25 * food-insecurity + 35.5 * human development Index]. Women, [colorectal-cancer = 6.47 + -0.23 * food-insecurity + 19.1* human development index]. The average difference between colorectal cancer observed versus the estimated, was -0.00 in men (95% CI: -3.13 to 3.13), and in women of -0.00 (95% CI: -4.08 to 4.08). Conclusion: food insecurity may be in the causal pathway of colorectal cancer. Food insecurity and the human development Index predict colorectal cancer.

BACKGROUND: The role that diet plays in the development of breast cancer is unclear and breast cancer continues to increase in Colombia and worldwide. The objective of this study was to assess the association between patterns of dietary consumption and the incidence of breast cancer. METHODS: An ecological study was conducted in 24 geodemographic units in which 95% of the women of Colombia live. The association between breast cancer rate (dependent variable) and three dietary patterns established with factor analysis (traditional/starch, fiber/dairy and snack) was investigated using simple and multiple linear regression. The use of variables related to socioeconomic context and the duration of breastfeeding allowed for the control of possible confounding. All information was derived from concurrent national surveys or was obtained directly over a period of time close to the period during which the study was conducted. RESULTS: There is an inverse relationship between breast cancer rate and illiteracy rate (ß=-2808.3), duration of breastfeeding (ß=-3354.1), adherence to traditional/fiber dietary patterns (ß=-30467) and adherence to the snack dietary pattern (ß=-43612). The goodness of fit for the model was R2=84%. CONCLUSIONS: Increasing the duration of breastfeeding, ensuring education to promote health and following traditional food consumption patterns, regardless of what foods are consumed, can protect against the development of breast cancer.
