The Impact of Improving Nutrition During Early Childhood on Education among Guatemalan Adults
基于危地马拉农村的纵向调查，发现早期营养干预对成年后教育成果有显著长期影响：女性多完成1.2年学业，男女阅读和认知测试得分提高四分之一标准差。
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.
