    Where is the highest rate of children with anemia in Peru? An answer using grey systems
    (Science and Information Organization, 2020-01-01)
    Anemia, or chronic malnutrition, in children under 5 is a social problem that affects the infant crucially in his or her growth and cognitive development. However, this problem presents itself in different ways in each department of Peru. Thus, in this work, the methodology of grey clustering, which is based on grey systems theory, was applied. The case study was conducted in the 25 departments of Peru, to analyze the departments most affected by chronic malnutrition in children under 5 years of age. The results of the study were that the departments of Cajamarca, Huancavelica, Loreto and Pasco have the highest rate of children with anemia; this may be due to the fact that these departments have greater poverty or negligence with respect to proper food handling. The results of this study could help local authorities such as the Ministry of Health to combat malnutrition, and also serve as a basis for future studies to evaluate the social impact of other conditions on health from a mathematical perspective.

    Impact of the Qali Warma school feeding program on chronic child malnutrition
    (Universidad del Pacífico Press, 2021-01-01)
    Este artículo aporta evidencia del impacto de Qali Warma sobre la anemia y la desnutrición crónica en niños de 3 a 5 años. Los resultados empíricos se obtienen por medio de una evaluación cuantitativa de dos pasos. Primero se usan técnicas de entropy balancing y machine learning para lograr un grupo control comparable que permita obtener estimaciones robustas. Luego se realizan regresiones para estimar el efecto del programa sobre las variables de interés. Se usan datos de la Encuesta Demográfica y de Salud Familiar de los años 2014 a 2017. Al parecer, Qali Warma no tendría efectos sobre la anemia ni sobre la desnutrición crónica, al menos en el rango de edad estudiado.
