Item type:Publication, Impact of micronutrient supplementation on chronic childhood malnutrition in Peru(Universidad Peruana Cayetano Heredia, Facultad de Medicina Alberto Hurtado, 2020-10-16)Chronic childhood malnutrition (CCM) affects mental and physical development of children. In the long-term, a high incidence of CCM generates a vicious circle of inequality and poverty. Therefore, evaluating the impact of interventions to ameliorate CCM may be a useful indicator of implemented policies. Objective: to evaluate the impact of micronutrient supplementation on chronic childhood malnutrition in Peru from 2014-2017. Methods: Data from Encuesta Demográfica y de Salud Familiar (ENDES) from 2014-2017 including children from 6 to 59 months of age were gathered. A two-step quantitative estimation was applied. First, the sample was balanced using Entropy Balancing (EB) and Machine Learning (ML). Second, differences in two variables were estimated, probability of having CCM and the Z score among those with CCM. Results: having consumed some micronutrient increases the probability of having CCM. A positive effect on the Z score was found above 54.1 sachets consumed. Results did not change after adjusting for covariates. Conclusions: micronutrient supplementation has a negative effect in reducing CCM, a positive effect was found at bigger consumptions. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, 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.
