FRANCKE, Pedro  and  ACOSTA, Gustavo. Impact of micronutrient supplementation on chronic childhood malnutrition in Peru. Rev Med Hered [online]. 2020, vol.31, n.3, pp.148-154. ISSN 1018-130X.

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.


: to evaluate the impact of micronutrient supplementation on chronic childhood malnutrition in Peru from 2014-2017.


: Data from Encuesta Demografica 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.


: 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.

Keywords : Micronutrients; child nutrition disorders; nutrition programs and policies; infant nutritional physiological phenomena; Peru.
