Acceso, frecuencia y calidad del agua para aliviar la inseguridad alimentaria y el hambre Jennifer Bernal Gabriela Ávila Rosa Hernández Héctor Herrera Zilanyaid Montoya Agrociencias agua hambre Caracas nutrición Venezuela La Agencia de Naciones Unidas del Agua celebró en 2012 el día del «Agua y la Seguridad Alimentaria», destacando que las personas beben de 2 a 4 litros de agua/día; sin embargo, la mayor parte del agua se encuentra en los alimentos consumidos. El objetivo del estudio es comparar el abastecimiento, frecuencia y tratamiento del agua con los niveles de inseguridad alimentaria y hambre (IAH) en hogares. Es una investigación descriptiva y trasversal, realizada en 1.251 hogares localizados en zonas suburbanas de Caracas, Venezuela. Por medio de encuestas se obtuvo información sobre el abastecimiento, frecuencia y tratamiento del agua, además del nivel de seguridad alimentaria, clasificada según la presencia o no de inseguridad, manejo de recursos y hogares con experiencias de hambre. Se utilizó el paquete SPSS v19 para el tratamiento y hasta 61,5% problemas en la periodicidad del acceso al agua. Los hogares con IAH moderada-severa presentaron un abastecimiento y periodicidad inadecuada de 72 y 77% respectivamente (p < 0,001). A medida que aumenta la inseguridad alimentaria, el abastecimiento, la periodicidad y el tratamiento de agua resultó más inadecuada (p < 0,001). La IAH vincula el acceso, uso y calidad del agua por su estrecha relación en la producción, preparación y consumo de alimentos. Políticas de protección en el uso del agua deben complementar aquellas que alivian la IAH. El reto es producir más alimentos, de mejor calidad y con menos agua. 2015 artículo científico 1316-0354 https://www.redalyc.org/articulo.oa?id=199241170004 es http://www.redalyc.org/revista.oa?id=1992 Agroalimentaria application/pdf Universidad de los Andes Agroalimentaria (República Bolivariana de Venezuela) Num.40 Vol.21
