Early Stimulation and Nutrition: The Impacts of a Scalable Intervention
通过集群随机对照试验评估了一项在哥伦比亚现有育儿项目中嵌入的儿童刺激干预措施，发现该干预改善了儿童发展（效应量0.16个标准差）并降低了5.8个百分点的身高不足风险，对发展中国家可扩展的早期干预政策有参考价值。
Abstract Early childhood development is becoming the focus of policy worldwide. However, the evidence on the effectiveness of scalable models is scant, particularly when it comes to infants in developing countries. In this paper, we describe and evaluate with a cluster-Randomized Controlled Trial an intervention designed to improve the quality of child stimulation within the context of an existing parenting program in Colombia, known as FAMI. The intervention improved children’s development by 0.16 of a standard deviation (SD) and children’s nutritional status, as reflected in a reduction of 5.8 percentage points of children whose height-for-age is below -1 SD.
