dc.description.abstractLa leche humana materna tiene una composición única para proporcionar a los recién nacidos todos los nutrientes esenciales como proteínas, grasas, hidratos de carbono, minerales, vitaminas y otras substancias fisiológicamente activas, con el fin de suplir en cantidad y calidad las necesidades calóricas y nutricionales del lactante. El objetivo fue establecer las concentraciones totales de cobre y zinc en la leche materna en sus distintas etapas: calostro, de transición y madura, determinadas espectrométricamente y la influencia del estado nutricional de madres lactantes; estudio descriptivo transversal en madres entre 18 y 35 años, sanas y no fumadoras; los resultados evidencian una disminución en las concentraciones de cobre y zinc a medida que la lactancia va evolucionando, además, el promedio de índice de masa corporal de las madres en período de lactancia reflejaron sobrepeso. Concluimos que el contenido calórico de los oligoelementos de la leche materna es esencial para el crecimiento de los niños por los beneficios nutricionales e inmunológicos que proporciona, por lo que es importante que la madre se encuentre en un estado nutricional adecuado que permita suministrar los requerimientos adecuados al niño para su crecimiento y desarrollo.spa
dc.description.abstractHuman milk has a unique composition and provides newborns with all essential nutrients such as proteins, fats, carbohydrates, minerals, vitamins and other physiologically active substances, in order to supply in quantity and quality the caloric and nutritional needs of the infant. The objective of this study was to establish the total concentration of copper and zinc in breast milk in its different stages: colostrum, transitional and mature milk, determined spectrometrically and the influence of the nutritional status of nursing mothers. We conducted a descriptive cross-sectional study in healthy non-smoking mothers between 18 and 35 years of age. Lower concentrations of copper and zinc as lactation progressed were observed. The average of body mass index of nursing mothers reflected overweight. We concludes that the caloric content of the trace elements of breast milk is essential for the growth of children because of the nutritional and immunological benefits that it provides, so it is important that the mother has an adequate nutritional state that allows to supply the adequate requirements for the child to grow and develop.eng
