The Impact of Improving Nutrition During Early Childhood on Education among Guatemalan Adults

Abstract

Using a longitudinal survey from rural Guatemala, we examine the effect of an early childhood nutritional intervention on adult educational outcomes. An intent-to-treat model yields substantial effects of an experimental intervention that provided highly nutritious food supplements to children, a quarter century after it ended: increases of 1.2 grades completed for women and one quarter SD on standardised reading comprehension and non-verbal cognitive ability tests for both women and men. Two-stage least squares results that endogenise the actual supplement intakes corroborate these magnitudes. Improving the nutrient intakes of very young children can have substantial, long-term, educational consequences. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
