The Sooner The Better But It’s Never Too Late: The Impact of Nutrition at Different Periods of Childhood on Cognitive Development

This paper investigates the impact of nutrition at different periods from conception to middle childhood

Abstract

Although it has been argued that undernutrition and its consequences for child development are irreversible after the age of 2, the evidence in support of these hypotheses is inconclusive. This working paper investigates the impact of nutrition at different periods from conception to middle childhood on cognitive achievement in early adolescence using data from Ethiopia, India, Peru, and Vietnam. In order to address estimation problems the paper develops a conceptual framework that delineates the channels through which child health impacts cognitive development and uses exogenous variation in nutritional status arising from weather shocks.

Young Lives is an international study of childhood poverty, following the lives of 12,000 children in 4 countries (Ethiopia, India, Peru and Vietnam) over 15 years. Young Lives is funded by the UK Department for International Development.
