Does the ICDS Improve Children’s Diets? Some Evidence from Rural Bihar
利用比哈尔邦农村调查数据，评估印度最大学前教育项目ICDS对儿童热量、蛋白质等营养素摄入的影响，发现对3-6岁儿童有效，但对领取口粮的幼儿无显著改善。
Although there are several studies documenting the impact of the Integrated Child Development Scheme (ICDS) – the largest preschool intervention – in India, few have documented to what extent it improves the quantity and quality of food consumed by young children. This paper attempts to provide causal estimates of the impact of the ICDS on calories, protein, iron, and Vitamin A intakes of children. Using matching techniques to define an appropriate counterfactual, and a primary survey in four villages in rural Bihar, our results suggest that: (a) for older children three to six years who benefit from cooked meals, the ICDS did result in higher intakes of calories, protein, and iron, and no substantive evidence that as a consequence there was substitution away from food at home. However, there was no impact on vitamin A intake; (b) for younger children whose mothers are given take-home rations, there is no evidence the ICDS improved intakes of calories or any other nutrients. Thus, even though the monetary value of the transfer was the same across both age groups, there is evidence to suggest the mode of transfer does seem to matter to ICDS effectiveness, consistent with other literature.
